Transporting (more) luggage with a Brompton

The Brompton rear carrier

• Custfold, Nov 1997:
  My original chrome plated steel carrier died after about a year, and the white (7 speed) bike has the cast alloy job [...]
• Ruud van Tol, Sep 1998:
  My 5-year-old Brompton has a much stronger back-carrier than my 1-year-old. I have transported many people of 60 to 80 kg, standing on the back-carrier of the old one. When I tried that on the new one, it broke almost instantaniously. My father-in-law managed to re-weld it.
• Clive Page, May 2000:
  I've just got a new Brompton to replace my old one (~13 years old and with rather a lot of bits needing replacement). It's an L5 plus a rear carrier (which I need to carry my briefcase to/from work) which is essentially a T5 less the dynamo lighting as I prefer to rely on batteries. [...]
  The rear carrier is now made of light alloy: no doubt lighter and it seems strong enough but when negotiating stairs I need to grasp the carrier in my right hand, and the new one is much sharper on the fingers. I've now wrapped some tape around the critical bit.

Stowing luggage on the rear carrier

• Channell Wasson:
  I use a barBQ grill bought at the local Iron Monger's (hardware shop)
• Simon Shearn:
  I've carried a box containing a self-assembly office chair on my T3. The box was an 80cm cube. It fitted quite nicely on the rear carrier and I secured in using bungees around the seat post. I wouldn't have been able to carry it on any of my "conventional" bikes. I've found that the large gap at the back, between the tiny wheel and the long seatpost, allows the Brompton to carry really bulky loads.
• Martin Whitfield:
  We often carry a spare Brompton to the railway station on a Bike-Hod trailer attached to either another Brompton or a large-wheeled bike.
• Dave Lyons:
  A couple of weeks ago I bought an 8' long white melamine shelf from a DIY superstore. I found that the corner of one end slotted into the rear rack on my T5 while the other rested on the handlebars and protruded out front, almost like a sail. I made slow but steady progress on the 2 miles journey home but had to be careful not to let the shelf interfere with the stearing. As you can imagine, I got a lot of looks from passers by!
• john_carss, Feb 1999:
  I've just read in a 'Cycling Plus' March issue, a review of 'Radical Design Brompton Rear Rack Bag' £65. Has anyone seen or used it? How big is it?
  The review reads as follow:

  Along with this firms's newly developed panniers for recumbents comes this bag,designed specifically for use with the award winning Brompton folding bike. The bag is made from tough Cordura proofed material and most of it is padded to add structural stiffness. The bag is secured to the rack by sliding the seatpost through the nylon hoop at the front. A snap closure ensures the rear part of the bag stays put.
  It was good to see a large, easy to use zip here, and there is a mesh upper portion for placing wet outer garments in. Natty finishing details include a hoop for attaching a rear Knightlite and hooks to accommodate a shoulder strap. (Paul Vincent)
  Cycling Plus verdict 4/5

• Custfold, Mar 1999:
  The secret is to get a ratchet down webbing unit (chandlers store) as used to tie down boats, and a miniature version of those things you see on curtainsider trucks or holding down loads on flat bed vehicles. Bungees are terrible for most load securing as they have too much stretch - webbing and the right buckle is much safer.
• Simon Risley, May 1999:
  Underneath the two rails that form the sides of the rack, and about two thirds of the way towards the front, are two small downward-pointing squarish lugs - one on each rail. They are of suffucient size and strength to use as "stoppers" to prevent any loads you carry from sliding forward and hitting your heels. Either by ensuring that the bungees' two plastic hooks are hooked in BEHIND the two lugs or, if your load is smaller, by attaching the hooks to the horizantal bar that has the two plastic castors (the way the bike normally looks) and just hooking the two cords on each side - or even just one of them - under the lugs. You can also cross one or both of the bungees on either side over your load and catch them onto the lugs on the opposite side, so producing an "X" pattern which holds your load more securely. It works very well.
  • David Hansen, May 1999:
    Sometimes I cynically think [the lugs] are for a different reason. If for some reason the seat is difficult to get up then they are excellently placed to put a hole in the bottom of one's shoe as one pulls it up:-(
• Custfold, Aug 2000:
  For waterproof luggage that takes A4/foolscap sheets flat you can't go far wrong with a UKP 2.99 Sainsbury box, with UKP0.99 lid, on our large carrier frame - waterproof but not watertight (ie will sink eventually if chucked into river). Or for watertight luggage get the frame with a top box (waterproof at 70+mph on a motorbike).

The rear carrier's bungee straps

• Martin Whitfield, Apr 98:
  No, it sounds as if you have some dodgy bungees. Mine (on two Bromptons over very long distances - one is five-years-old) have showed signs of stress when stretched over very large objects, but have bounced back to life in a couple of days. They are replaceable so I'd ask for some more.

Weight capacity

• Dave Holladay, Aug 2000:
  The rear carrier will carry 1 average size adult - say 70Kg.
• Stein Somers, Aug 2000:
  Hmm... I've seen you abduct Linette Chiang at Folder Forum III, but I bet she's under 50kg. A girl who cannot weigh more than 70kg (I couldn't ask, obviously) once placed her foot on mine, without fully standing on it, and already one of the stays broke. I broke once of the four bars by misplacing my foot while the bike was folded.

Heal hindrance

• Channell Wasson:
  If one is carrying a box or bag on the rack, the load generaly comes sliding forward so that one's heels hit the load on the rack. Quite an anoyance! Therefore it is important to adjust the rack load so that it does not cover the last two inches of the rack nearest the seat post. To accomplish this I have installed two small plastic T fittings (1/4 or 3/8ths id) [T fittings are plumbing or conduit 90 degree tees] secured to the rails of the rack with zip ties. When carrying a load I simply turn the fittings up so that the rack load can not come forward. A simple light weight solution that works like a charm. Another tip is to run the stretch rubber lines (elastic shock cord assembly) under the rack. When using them they can be pulled up from inside the rack. This will also help prevent the load from moving forward.
• Custfold, Nov 1997:
  The rear rack does work if you have small feet, with the Brompton front pannier placed with pockets facing down, either side of the rack, and well to the rear. alternatively the 4 litre panniers I have sit clear of my size 10 feet, hooked right at the back of the rack, and no further forward than the axle. If I could get the right glue I've a watertight floation/stuff bag from a canoe, which will clip onto the seatpost, and hold around 40 litres, and others have used roll stuff sacs up to 9" diameter sitting vertically.

Adding a rear carrier to an L-model

• Andrew Henry:
  Its quite a lot of hassle to add the rack from an T5 to an L5. The rear mudguard and the front mudguard stay have to be changed. A dealer can order all these bits from Brompton, but they certainly wouldn't keep them in stock. If you want the rear rack, its probably cheaper to buy a T5 and remove the dynamo. Its certainly less hassle for your Brompton dealer.
• Channell Wasson:
  Racks are available as an after market item, but the are tricky and time consumming to instal. The fender must also be changed in the process and the brake assembly must be readjusted. It takes over an hour to do the job.
• Custfold, Jan 1998:
  The rack fitted to the Raleigh 20 (available as a spare can be fitted to the Brompton but will require butchery and extra bits made - it will be less rigid (only 1 set of stays) and will not incorporate the means of wheeling/and parking which the standard rack offers. The conversion kit is expensive because you get the proper mudguard (different between T & L) and the elastics, rollers etc on the rack. It's worth the money - but note that the lights and dynamo are not supplied - but the D Toplight Standlicht makes a much neater job of a rear light & reflector set than the 2 pieces used as OEM kit (and it stays on when you stop)
  We make the D Toplight up with a bracket to fit the T type rack as a kit.
• Frank Tompson, Feb 98:
  Having mulled over the options I decided to have a bash at diy. I used one of my favourites, half inch angle aluminium (light, easy to work), joints drilled/bolted/Araldited. Painted with black enamel - should have used Hammerite.
  Maintaining foldability meant a very tricky escapade but in the end success, albeit very time consuming, what with designing, buying in bits, modifying, etc.
• David Henshaw, Feb 98:
  Many years ago, thinking like many others that the Brompton rack was on the pricey side, I set to work with an oxy-acetelene torch, an old toasting rack and two Hillman Imp (that's Sunbeam in the US) battery mounting stays and built a serviceable rack. It's lighter than the kosher job, much cheaper, has little wheels to drag it around on, and it looks horrible. If anyone should want to inspect it closely (why?), it's on Jane's Number One Brompton - still giving good service after five years.

Reparing the carrier

• David Hansen, Jan 2000:
  [...] waiting for some new struts for the rear rack. Two have broken and Brompton want to sell me a new rack rather than just the struts (which they buy in). When I buy a bike for that price from a small manufacturer I expect to be able to get spare parts for it.
• Custfold, Jan 2000:
  I needed longer struts for the Nexus 7 conversion, as the old ones are too short to reach the widened rear end. I took off both the old ones and fitted one new strut made from 1/2" U section aluminium which had the ends drilled to take 4mm bolts in place of the rivets, and slotted out to clear the casting web and the drop out stamping.

Alternative front/rear luggage racks

• Channell Wasson:
  I have worked out two solutions. I have a double deck rack system for rear of Brompton. I use a Moulton Model 20 APB rack raised 2 feet above the Brompton rack.This rack is available from Bromptonite Roger Grigsby of Santa Cruz, California. A clamp I had made grips the seat post and a strut (Moulton strut) goes from rear of Moulton rack to nut on seat post quick release fitting. This is a wide and ample rack which was designed to carry the Moulton suitcase. Now on the Brompton bottom rack I have attached an 18 inch diameter circular barbeque lightweight grill. It is just the right size to support my Moulton canvas suitcase. The rack is quite sturdy enough and as a bonus it is chrome plated and I think looks mysteriously smart. Loaded racks do eliminate the rear wheel fold under feature of the Brompton.
• gert de jong, Aug 1997:
  I'd like to mount Karrimor front/rear panniers on the Brompton rear carrier. I have an old version Brompton with the steel rear carrier instead of the alu carrier fitted nowadays.
  The (only ?) good thing about the steel carrier is that the diameter of the steel bars are is in correspondence with the clamps of the Karrimor panniers. The remaining question is: how do I keep the panniers away from the hub bolts and gear control chain(s)?
  Refraining from doing so causes excessive wear on the panniers where they rest on the bolts and makes changing gears difficult.
• Chris Eacock, Jun 1998:
  [...] use one of the racks that clamp-on to the seat post. This would be placed high enough to install panners and be clear of one's heels. I have the Topeak model (with a quick-release).
• Scoman, Aug 1999:
  I use one of these [Top Peak Luggage Rack offered by Brompton USA] occasionally for my L5. When I attach it to the seat post and slide it down just right, I can attach full size ortlieb panniers. The top hooks clip onto the luggage rack, and the bottom hook slides right into one of the stays that hold on the rear fender. Works great for when you want to carry some extra stuff.

Stowing luggage on the front

• Custfold, Sep 1997:
  Took 100 Primos to the carrier today for a shop delivery, and used the Brompton, with the large carrier rack. Total on front c.25Kg - bit of a pig to handle with load extending so far forward, but otherwise OK. Speed limited by load swinging around rather than total load.
  The groceries I picked up on way home seemed easy in comparison.
• Custfold, Nov 1998:
  We shop with our bikes - and the local Somerfield is especially bike friendly. Normally (must fix the bracket) I go down to the shop with the front carrier rack (large size with 20cm supports) empty. On arriving I place a store basket on the rack - which it could have been made for - the fit is so good. I place shopping in the store basket just like any other customer - except I'm not burdened with the weight. If it is a very large shopping I might put a basket on the T type rack but it needs to be tied on (elastics) or carefully balanced.
  Once we have finished we take a walk past the fresh fruit island, and pick out a grape, tomato, melon, orange, or apples box of the nice stacking cardboard variety, or if it really is a big shopping 2 or 3 of these. The box is tied on to the front rack, and the shopping loaded, if a second box is needed the stacking system helps to locate it. 2 apple boxes is usually a weeks shopping for us, and pushes the limit well over the recommended 16Kg for the front carrier bracket.
  We usually find plenty of uses for the boxes once we get home as stacking filing trays or tool boxes - even Brompton spares (16" tyres fit into apple boxes just nicely). Here is a picture of the system carrying home the filing system (8 tomato boxes stacked on the front).
  Racks are £24 and £26 for 6" and 8" support sizes.
  We've also made a bag which takes the store basket inside, and you then take the basket out and load the bag. The ubiquitous Newspaper sack on the Brompton frame is also a very cheap option for those who whinge about spending money on anything!
  
• Len Rubin, Nov 1998:
  I used to shop at Rainbow all the time (I assume you are referring to the S.F. store by that name), in the old days, before the big move -- how weird to hear about that new rule! Well, I designed and made a couple of huge front bags that hold two grocery bags each and we shop with them all the time (Real Foods, Whole Foods and Mollie Stone's). We usually fold up the Bromptons and stick them in a shopping cart (trolley for you Brits!), wheeling about the store to surprised (and sometimes familiar) smiles.

The Brompton front carrier block

• Channell Wasson:
  The carrier block seem very sturdy and I can only say I have often carried 10 to 15 kg in the pannier or basket.
• Doug Faunt:
  A bit of anecdotal evidence about the strength of the front block. I broke mine, by "tripping up" the front wheel in a cross rut when riding very slowly on a cowpath, and going headover. The block broke, and the carrier frame bent slightly, because I went over the front, and my whole 180 pound weight was pushing the right hand end of the frame.
  I have been unable to straighten out the frame using simple techniques, which means it wasn't easy to bend, and seems to indicate that the block is quite strong.
• Phil Gough:
  I and someone else mentioned the mounting of Samsonite-type briefcases, when filled with the usual clutter the weight upon the mounting block was I should think up to 15 pounds. In over 8 years of daily use the only effect this had on the block was for the mounting screws to loosen, this happened twice only. This could be because the case being rigid and taller than the Brompton bag vibrated and rattled a lot.
• Custfold:
  I have carried considerable unknown loads, on the front block, and equally experienced screw loosening. As an insurance I cut a slot, and threaded a jubilee clip [for Americans: hose clamp] through the block, and around the back of the head tube - result less frequent loosening. The critical issue is not I expect the total load, but the moment forces from a wide load swinging from side to side, the block happily took a 56lb weight in the child seat, for testing, but made the bike heavy to steer.
• Phil Gough, Oct 1998:
  There is a front bag carrier block available which can be fitted to several different kinds of bike, including early Moultons or even the average gas-pipe shopper. It is modelled on the Brompton block and is sold by Cyclecare. [54 Earls Court Rd, tel. (0171) 460 0495] The cost is about ukpounds 30. Cyclecare is a major London Brompton dealer.

The Brompton cloth front pannier

• Bruce Boysen:
  [ contemplating his babe magnet (Stories featuring Bromptons (all true) - Babe magnet) ] Anyway, the basket is great, it pops on the headtube in a second, holds a lot & doesn't impact on the handling much at all. Much easier to use than panniers for shopping runs & also holds large stuff you couldn't put in panniers.
• Stein Somers:
  I bought the pannier and block and was instantly satisfied. Easier, quicker, neater, even safer as it constitutes a kind of bumper.
• Andew Henry:
  Its moderately weather-proof. [...] The metal handle can be a bit cold in the winter, so I wrapped it in tape. The balance of the bag is fine. The only problem with it is that the handle is a little narrow, so it can dig into your hand if you carry a lot of weight in it (ie fill it full of books). Of course if you have your Brompton with you, and you need to carry it for a long way, then you can unfold the bike and clip it onto that. Overall, though I don't find it a problem to carry.
• Dave Lyons:
  It is much easier to carry fully laden with a shoulder strap fitted on the red loops on the top. With the corner pockets facing inwards (towards you) the bag is comfortable and does not slide around.
• Custfold:
  There is a solution to the waterproofing of the front pannier bag available now and potentially free. Just ambush the local paperboy/girl and hijack the excellent plasticised sack in which the papers are carried. Turn this upside down, and it will slip over the Brompton pannier almost perfectly. The top flap can be either tucked up, fitted with velcro tags to connect onto the rear, or the shoulder strap shortened to hold it up under the Brompton Pannier rack. All of these allow the pannier to be detached without removing the rain protection.
  These bags come in excellent bright orange or yellow colours, and if you find reading the name of a local paper upside down, as you ride, a nuisance, then a couple of good hot wash cycles usually cleans the bag spotless of print and all but the worst tar spots.
  Custom Folder does have a source for these bags, but there is a minimum order quantity, so let me know if you want one and don't wish to mug the news delivery kid.
• Martin Whitfield, Apr 98:
  While on the subject of Jane Henshaw's bag products, may I recommend her waterproof front bag cover.
  I was surveying a map for Leicester during the two wettest days of the year (Thursday and Good Friday) of Easter week, when rivers were rising and floods were everywhere. Not a drip penetrated my Brompton bag and its contents. Maps, being paper products, are particularly sensitive to water and they were dry as a bone. Head to foot Gortex helped me keep dry too, but my shoes were soaked and I could pour water out of them.
• Channell Wasson, Oct 1998:
  If you want to be waterproofed in the front pannier area, then get on of Jane Henshaw's pannier covers. They slip over the entire pannier assembly. They are of waterproof fabric and come with sealed seams. They look very good to me. Contact her at A2B Magazine.
• Rob Cope, Oct 1998:
  Yes, the A2B covers are very good: have had one for a while, tucked in the pocket under the handle. Improve the basic bag design & it might not need its own showercap.
• Rob Cope, Oct 1998:
  Since some of its shortcomings have come up for discussion:
  I am rather disappointed with the details of this. It is a fairly expensive bag made principally of high-grade Cordura but to my mind shows definite "spoil a ship for a ha'perth of tar" characteristics.
  It is never going to be totally waterproof, but could be a great deal better if the flap over all 3 zips was extended by about 2 cm & possibly fastened down eg with Velcro. The present short flaps do little to prevent water seepage via the zips (which on mine are pretty poor quality: I trust Carradice now specifies better zips). It would also help if the base was not pop-riveted right where road-splash is likely to hit.
  The 2 loops are useful, but are fixed to the bag, not the frame, so should be used with caution if contents are heavy or precious.
  It really is about time it got some reflectors fitted as standard: you can buy stick-on tape etc but Cordura is hard to stick things to. Carradice used to do the bag to order in non-standard colours: is there such a thing as a retroreflective Cordura?
  The materials are good & Carradice does offer an excellent repairs service. But I do think the design is in dire need of updating.
• Willi Mindak, Oct 98:
  All valid points. While we're re- designing the bag: couldn't it be made bigger? I believe in increase in depth would be problematical because the bike's handling may be affected. But an increase in height (and possibly in width) is possible, even if it were only a couple of inches. In addition to that 2 adjustable loops with quick releases should be added to the flap, so that it's possible to tie an additional item (i.e. waterproof jacket) 'rucksack style' to it.
• Custfold, Oct 1998:
  If you lift out (or when it falls out) the plastic stiffener you will find very basic seams which are not - IIRC the right term - overlocked.
• Tom Bennett, Aug 1999:
  I used the Pannier system regularly. It works great on the bike, but it's a bit heavy to lug around museums etc, and the aluminum frame digs into you and innocent bystanders. But I found it to be an absolute necessity for day trips outside of Paris. We would leave our apartment in the shadow of the Eiffel Tower, bike up to Gare Nord, fold up the bikes, hop on the train to Chantilly, and bike up to the medieval village of Senlis. In our Panniers: Water, sweaters, maps, tire kits, a book, binoculars, camera, sunscreen etc.

Is it waterproof?

• Larry Chinn, Dec 1999:
  I've ridden my Brompton a few times in the rain and haven't noticed the bag to leak. I have to admit, I was only out for maybe fifteen minutes at a time and it's been a pretty dry winter here in San Francisco.
• Robert Payne, Dec 1999:
  I've had the bag leak for me. The leaks really seem to start when enough water starts to pile up on the top of the bag. Once this happens the fabric becomes saturated and water eventually goes through.
• Rob Cope, Dec 1999:
  This is usually the stitching, more than the zip leaking (though better flaps covering the zips would not go amiss). Use the sort of sealer camping shops sell for tents etc (tube better than spray). Helps a lot (not as much as a cover though).

Making it waterproof

• Jane Thomas, Oct 1998:
  Actually you can make it almost waterproof with a tube of Grainger's liquid seam sealant (or similar)- I found most of the leakage was through the top seam, not the zip. A liberal application of aformentioned seam sealant to all exposed seams made a vast improvement.
• Rob Cope, Dec 1999:
  You can buy [a cover for the front bag that is waterproof] by mail from the maker, Jane Henshaw of A to B (Where can I find out more? - A to B}. They are very fluorescent yellow & cost UKP20 plus an extra UKP1 for orders outside the UK. Jolly good they are too.
  Address: 19 West Park, Castle Cary, Somerset, BA7 7DS
  Lightweight bike covers also available for UKP18 (same deal on shipping costs). A to B has a dollar account, so you should be able to use US checks: contact post@a2bmagazine.demon.co.uk to confirm.
• Nico J. de Boer, Dec 1999:
  If you don't mind the grey colour and cheapish looks, you can try a dustbin liner. Works perfectly for me: leightweight, folding small, 100% water resistant.

Brompton touring bag

• mark james, Jun 2000:
  Goods - Big, Handy mesh outside pockets. Looks less smart but very roomy for light and bulky items.
  Not so hot - Closure awkward on the move and no adjustment on main compartment no straps to tighten up if only partially full - major minus! PVC lining, nasty substance.
  No real test in pouring long term rain yet, Although doesn't pretend to be 100% anyway.

Other panniers on a Brompton

• Graham A. Patterson:
  I have used a Karrimor rackpak on the rear carrier with success when touring. I strapped two rucksac pockets on the outside for extra capacity, which meant that I had to secure it well back, level with the rear brake. It was secured by running the two carrier bungee cords over the top. The rackpak has shoulder straps. The capacity is similar to the Brompton pannier, but less flexible in use because of the shape.
• Andrew Mackay, the red flash around London's round-a-bouts:
  You don't need a front carrier system at all on a Brompton.
  I have used a simple small "back-pack" that cost £9.99 and can be found in most luggage shops. They all have a loop at the top to hold them like a suit-case. You'll find, if you loop this over the tip of the saddle and then push it around to the back of the bike, that it is very firmly fixed by the weight of the bag. You have to sit on the loop but this is not too bad. The only addition you need is to sew a velcro band to the Zip side of the bag to stop it moving sideways or forwards away from the seat pillar when you brake or pedal. You need to have the bag orientated so that the side that would normally be on your back points backwards from the bike to lessen the stresses on the zips. This technique utilises the empty space available because the Brompton has small wheels and is so foldable. On arrival you undo the velcro, slip the bag round & forwards and it comes off very conveniently. You could use any size of bag you wanted provided the loop is the correct size for your saddle (a soft saddle cover helps).
• Jane Thomas:
  [ There was a letter in the Folder a few issues ago from someone who made their own bag to fit onto the metal frame from the Brompton pannier. This was quite a bit bigger and had a roll-top like on an Ortlieb pannier, which made it completely waterproof. ]
  That was me - if you want to have a go at making your own, the pattern and instructions can be found on my webpages - http://www.toehead.demon.co.uk It's not really bigger, you can just get more stuff in due to the design. I think it looks smarter than the existing Brompton bag (but then again, I would), and you can make it any colour you like.
• Jane Thomas, Mar 1998:
  I'm sure a lot of you are already aware of my front pannier patterns - I'd just like to let you know that I've finally added (long promised) back pockets. I've reshaped the back slightly to allow for a small 3rd pocket to be added in the middle, and have made patterns for either zip- top or roll-top pockets.
• Dave Lyons:
  On the subject of front carriers, I recently bought a extra frame for use on my partners Brompton and my own. I have attached to it a large 30L capacity white plastic coated freezer basket which I found lying in the street. The basket is secured to the frame by 3 medium sized cable ties and when I tried it out for the first time it worked perfectly. I used to secure this basket to the rear rack, but no more. I feel quite smug waiting at the checkout with the basket full of groceries on the parked Brompton.
• Philip Hall, Oct 1997:
  I have a Neobike (Taiwanese) Brompton. I'm told it does not fit the front carrier block and, anyway, I already have lots of bicycle luggage so I have fitted a small aluminum bar along the lower part of the handlebars. This luggage bar has a notch cut for the handlebar-mounting bolt so that it essential sits on this mounting bolt and is held level by two nylon straps.
  The point of this is that I can mount an ordinary bike pannier across the front of the bike. I can even put a large soft motorcycle pannier and still have room for my headlight mounted above the front wheel.
  It works great! There are two problems to be aware of: I'm not sure of the strength of the tall steering stem so I am leery of overloading the bag. The second problem follows the first: it is easy to put heavy loads in big bags and regret it later. One must still remember to put v.heavy things on the rear rack.
  However, for taking my lunch and raingear to work it is excellent.
  • Custfold, Nov 1997:
    There are 3 problems - most delivery bikes have the load carrying basket attached securely to the main frame, thus keeping the weight evenly distributed. The Brompton design of carrying system is very well designed in this respect, as it has the load secure, over the front wheel, and not swinging about with handlebar movement, which becuase of the bike's design is more pronounced than a conventional bike in effect when a load is carried on the bars.
    One option (IIRC the Neobike uses a small diameter steerer (1" not 1.125" as the current Brompton) so you could get a Brompton front frame section - possibly one which has been damaged in a crash, and cut off the main tube to leave a unit which will slip over the 1" head tube, and with a small slot cut in it can be squeezed up around the existing head tube, or buy one of Tim Whitty's adaptor plates and clamp it on with 'Jubilee' (aka hose) clips - some day we'll educate those US mechanics into the proper nomenclature for parts, or sell them an English-American dictionary. :-))
• Custfold, Dec 1997:
  I think I've cracked the fixing details of the mini panniers for top mounting and perhaps the sides also.
  The 4 litre mini pouches sit on top of the rack, and hang at the back behind the rear axle - thus clearing all but the biggest plates of meat (plates if you were born within the sound of the great bell at Bow).
  I've also used a nice gift from Radio 2 to good effect - guesstimate at 25-35 litre capacity, and perfect fit on top of the rack, with stabilising tie clipped to saddle rails. Something in new year I hope.
• David Henshaw, Feb 98:
  We have a couple of very large home-made bags and brackets that we use on our Bromptons. They weigh much less than the Brompton bag and frame, cost much less, and carry up to 30lbs (13.6kg) quite regularly. They've now survived for four years without mishap, including many off-road miles and one journey (part off-road) of 70 miles. I just wish someone would put something similar into production... I've never heard of a pannier or bracket failure, but I would not recommend exceeding 30lbs, because the bike's handling begins to get a bit sticky at that point.
• Custfold, Apr 1998:
  We now have models of a shoulder carried bag for the Brompton, a large front bag - which is designed to take a supermarket shopping basket sitting inside, but will pack away flat when removed from Brompton carrier rack, plus a waterproof bag - which may have some minor dimensional adjustments to accommodate speed skates for the Dutch market with 50cm blades. All in true Henry Ford colour scheme, with nice matt external finish (it's Jo's fashion background I reckon).
  I've sorted out the 4 litre pannier fixings for sides and top of the rack - it's now just a question of making the brackets look a bit more respectable, and likewise the V brake mounting system for L & T models, it works but could look nicer. V brakes are hot stoppers though. Note that the front bag is pocket less, but we may fit the mountings for the 4 litre panniers in the appropriate places to attach a set in front also.
  For the minimalist we also have a shoulder strap and attachmants to carry naked Bromptons around which is coming along nicely.
  Note that the anti - fold under strap is available at some Brompton dealers (Avon Valley) as well as direct - other popular items will eventually appear on retailers' shelves also.
• Custfold, Apr 1998:
  I've now got 14 (8 small / 6 large - 2 already allocated) of the C=F carrier rack for the front block - finished in black powdercoat crackle finish - from initial production run - hope to have one to DH for review soon - small weighs 420gm, large 620gm approx.
  We may be able to reduce this further still if we can streamline some production details.
• Dave H, Jun 1998:
  If you really want 100% w/tight it is possible to fit a Voyageur canoe flotation & luggage pouch onto the rear rack vertically with the seal bar clipped onto the seat post - but I was having difficulty sticking the U lock clips onto the nylon seal bar (which has to go on at an angle.
  The same bag might also fit the front carrier, but we have a compromise of a bag with proper seams (the Brompton ones are a bit basic, and it leaks here first) and seal this with the Voyageur seal bar making the bag almost airtight - like the sealed seam OEM flotation luggage mentioned at start. A further option is to mount the York 80 box on the front carrier - a box designed by Joel York for Voyageur (?) to float with 80 lbs of payload, and in polymer casting with neoprene seal ISTR around $70 or $80 retail price. It can carry with rucksack strap kit, and I clocked mine with 24Kg on front rack fitting one time.
• David Cox, Aug 1998:
  I find that I can carry a fair volume of light bulky kit - mainly clothes - on an L3 by using two toe clip straps to tie a sports bag by its handles across the top of the Brompton pannier. This works with a folded suit for special occasions at work and also did for the Folder Forum weekend.
• Ian R. Platt, Sep 1998:
  I got the aluminium frame and then a courier bag from Halfords, which seems - tho it's not been tested yet - to be waterproofed, at least on the sides, tho it's a flap top not a zip. It was (IIRC) half the price (or less) than the Brompton bag. It is quite large and fits at least 4 boxes of cereal, 2x six-packs, films from the hols,. and a clock for repair. I sewed some nylon tapes lined with Velcro (strength + easy of attachement) on the back and bottom and the bag and these fit round the frame

  Cost: £15 or so.
  I also got Halford's rear frame bag. Not huge and I haven't used it yet & obviously it won't stay on when the bike's folded (else it would be underneath, right?) Again, a cheaper than Brompton arrangement Cost: £9.99
• Jane Thomas, Oct 1998:
  For those intrepid soles who would like to make their own, my pattern is available on my webpages. And for those intrepid soles who have made their own, can I trouble you for a piccy? I'm constructing a gallery of what is possible - I already have Jane Henshaws cowbag, my clearbag and David Hansen's original rolltop - my blue velvet snakeskin will be added as soon as I've made it ;-).
• Custfold, Oct 1998:
  In designing our bag, with the slide seal on the top Josephine used her 20 years in fashion & clothing design to make a more waterproof seam (and with the right material we could make the bag in a welded seam as the canoe luggage we have brought in uses) to make bags which carry clothing and double up as bouyancy because they are airtight. Our bags are 'airtight enough to make a bouncy balloon, but without a fully sealed seam they do leak slowly down. The material is a coated Nylon which comes in an attractive Ford Black or to special order in other colours. We also make a carrying sack fro the Brompton which goes over the shopulder like a posties bag.
  For a low cost option in 2 guises consider buying a news delivery bag from the local paper publishers - these are a coarse but HD nylon coated in PVC - usually bright orange or yellow. A couple of boil washes in strong detergent should remove any printing from the bag and make it 'very' clean. Prices vary - if you're a good bargain hunter - free or bribe the paper boy/pay around £3-£5 for a new one from the paper distribution centre
  Option 1 - buy a Brompton pannier frame - fit plastic stiffener sheet to back/front and bottom of the bag (glue - pop rivet etc). With webbing straps or other fixings attach bag to frame and voila a bright coloured front pannier - a bit short usually on the front flap, but fitted backwards it presents a 1 piece face to the oncoming water.
  Option 2 - you have a Brompton pannier - invert the bag - rear of bag to front of pannier and slide down over the pannier, bringing the top (now bottom) flap back to cover the underside. With either 2 velcro straps fitted to hitch this flap up to the rear, or using the strap attached to the bag pulled tight, keep the flap up clear of light and wheel.
  This has an added bonus - most news delivery bags are just big enough to fit an L type Brompton inside and use as the carry system - our sack is just a slightly larger version with some luxury extras (long flap, detachable strap that can be used without the bag etc).
• Joerg Scheiner, Oct 1998:
  I have been using the Brompton bag for 3 years. But it is now heavily worn so I decided to by a Velo case. This is an Rimova aluminium case pictured in the first or second encyclopedia. It has about the same capacity like the Brompton bag and has a quick release system that allows to fix the Case to the Brompton frame. Onle problem is that jou have to remove the frame to allow the case to be fully opened. I wish I had another frame without the preshaped handle (to facilitate opening) and without the bottom bracket (to avoid damage to the bottom of the case.
  As it is a hard case it is very robust and it is waterproof. The shape is like a pilot case but not so wide. It holds 3-4 Leitz binders (A4).

Front bag jumping off: front carrier block maintenance

• Rob Cope, Sep 1998:
  There is a little (essential) play in the system: as the block wears slightly this play can increase, sometimes enough for the sprung tongue to escape the matching rebate in the bag frame. The solution is to make the tongue stick out further. Do not try bending it... SNAP! Unscrew it (keep hold of screw & washer) & sand down the back at a slight angle: enough to increase the angle of the tongue (rotary sander with fine paper helps - but careful now, you only need take a little off). Reassemble & problem should be gone: bag will snap into place reassuringly like it used to. Dave Henshaw is the expert on this.
  BTW I find the allen bolts holding the block on slacken fairly quickly: annoying, as the tongue then has to come out (cheesehead selftap screw - would a matching allen bolt cost much more?) before the allens can be tightened. Solution: a smear of locking paste applied at factory or by dealers?

A laptop in the front bag

• davidh@spidacom.co.uk, Oct 1998:
  I only do so occasionally, but when I do I put a coat in the bag for it to rest on. If I did it regularly I would make a box with foam for it to sit in.
• Vince, Oct 1998:
  It is not wise to put a computer in any bike carrier. The vibration is extremely likely to cause problems later, if not sooner. One good jolt and your computer (which most likely costs more than your Brompton) will require repair or replacement.
  I recommend carrying an intelligent keyboard which is solid-state and light- weight.
• mike, Oct 1998:
  I put mine in the carrier... I have made a bubble wrap envelope for it... it's stood 5 months of rattles, jolts and weather.
• Liduine Reuser, Oct 1998:
  Yes, I always put mine in the front carrier. I wrap it in a plastic bag (the Brompton-bag is not water-proof!) and I put the whole on a plastic raincoat (of course not when it's raining, then I wear it). It might be a good idea, like Mike wrote, to wrap it in bubbled plastic. There is a difference of opinion on this list on whether you can take a laptop or not. I think it's a matter of the risk you want to take, considering the following aspects : 1. The quality of your laptop 2. The ownership : is it your own or your employers laptop ? 3. How often you make backups I have a Toshiba, owned by my employer, and I make backups often. Besides, I don't want to commute (I have to change train/tram a lot) with a Brompton and 2 bags. And a backsack is uncomfortable, you're sweating more. So, taking all this in account, I take the risk (is there is a risk). I've been doing this for half a year now, and the only harm is some small spots on the outside of the laptop.
• Andrew Heyting, Oct 1998:
  When I got my Brompton L3 (about a month ago) I also bought the front block and carrier frame.
  I have adapted a Solidex Laptop bag to fit permanently to the carrier frame, which is padded & has velcro fixings for the laptop. I carry it through London every day. The bag is made from synthetic leather (i.e. plastic) and so is waterproof, and the laptop seems fine. When off the bike the bag has a shoulder strap, which also makes life easy.
• Mike Hessey, Oct 1998:
  I have regularly carried laptops in the front bag of the Brompton. I wrap them in bubble plastic, which provides a bit more protection from vibration etc, and also provides some additional protection from any water that might get into the bag.

Saddle bags on a Brompton

• bruce boysen:
  I also have this great saddlebag (yes, it hangs from my saddle) made by Carradice in England, called the Camper Longflap, & it is HUGE, with just two of these you could go on a loaded tour! This saddlebag is one of the coolest, most useful bike items I've owned. The Rivendell Bicycle Works catalog writes about them, "Carradice saddlebags are so unfashionable, people you don't even know will ask you about them. Even other cyclists!" BTW, Carradice also makes the basket for the Brompton & they go well together.
  Carradice makes several wonderful saddlebags out of heavy cotton duck with thick leather straps. They are the traditional saddlebags that have been made for a long time. They are not quick release (quite the opposite), but the seat can be almost fully collapsed just by unfastening one buckle around the seatpost. The straps are not sewn on the bag & may be removed & replaced with quick release straps if thats what you want. I have the Camper Longflap which is HUGE, but my catalog (Rivendell Bicycle Works) lists two smaller models also. I bought mine mostly because I love high quality traditional stuff like this & it has turned out to be very useful

  {Malcolm Lyon} Yes, I also use the Camper model it is big and will last for lifetime .. but you will realise that whilst the fabric is water and bullet proof the design does not exclude water from the flap edges. It is important to put clothes in a plastic bag and use the saddle bag as a sort of compression bag!
  Readers around the world may be interested to know that these Carradice bags are used widely by members of the British Cyclists Touring Club and more or less 'de rigueur' for well dressed CTC bike!
  The leather straps a bit tedious to unbuckle. And there has been a chap selling a very nice quickly detachable saddle fitting - I don't recall his name [...]. The fitting is well made in anodised aluminium and would not restrict the folding of a Brompton. He also makes an uplift version for conventional bikes where the saddle is close to the rear mudguard. I can identify the source for these if requested.
  I have said they are very easy for practical person to make and require only a short length of ally strip a piece of dowel rod and an old QR hub skewer. Difficult to describe in words but I am happy to send a sketch by fax to anyone interested in making one. Or I could perhaps scan a tif file to attach to an email .. but I have not tried this on my computer.

  This months [april 97] issue of the CTC magazine features on page 41 the Kwiklift attachment for the Carradice bags. This is ideal for folders as it enables the bag to be rapidly removed when the bike is folded. It comes in two versions. 17 pounds for the basic bracket plus another 10 pounds for the additional bag support which may add some stability to the bag but is really designed to eliminate pressure on the mudguard of a big wheel bike. Available from

  W.G. Lord 4 Kenilworth Gardens Newton le Willows, WA12 8ES Phone 01925 224125 in evenings

  ... it is nicely made and anodised.

  {Malcolm J New} I have recently completed a short tour of the Isle of Wight on my T5 model traveling a total of 60 reasonably comfortable miles. I used a Carradice "Super C" front box (with Klick fix fittings) and a very large Saddle Bag in the same range. The "Super C" saddle bag is similar in size and shape to the Carradice Camper Long flap but with more modern quick release buckles and quick release straps for removal prior to folding.

• O'Flynn, David D, Apr 1999:
  My L3 Brompton gets daily commute use as well as w/e action. For all these activities I have found the small Brompton bag that hangs from under the seat too small (e.g. A4 papers will not fit in it, nor an assortment of items like camera, wallet, water bottle simultaneously) and the Brompton front carrier bag too large and too ''un-aerodynamic''. I started looking around in March and found an attractive alternative last Monday, which is now used everyday -
  Noir Sport - Washbag
  GBP12.00
  Colours - Red shiny nylon weave with Black vinyl trim or Navy Blue nylon with same trim
  Water resistant
  2 zip pockets, 5 open pockets
  Dims - folds flat empty, but when full is H21cm x W23cm x D12cm
  Source : travel accessories shop Gullivers in Victoria Station, London. Apparently this is a UK-wide chain. tel 0171 828 2190
  I have attached it to the seat back lugs (used by the Brompton seat bag) using black velcro, costing just a few pence. A4 size papers or stiff materials do not quite fit and so have to be bent/folded in half or else rolled up in a postpak type cylinder. Colour co-ordinated (for r&b bikes), trendy and functional all-in-one!
• David Dodson, Apr 1999:
  Use a supermarket-style freebie plastic carrier bag. Fill it so as to avoid the bag bulging too wide, and simply hook both handles over the back of the seat. If the handles don't fit over the back of the seat, the hand-holes can be torn/cut downwards as necessary.
  The handles being thin plastic have no effect on comfort; Once the bag is correctly aligned it tends to remain so. I have my seat pointing down quite a lot at the front anyway but I doubt this is essential.
  Specifications:
  (A) Functionality:
  Safe load: probably about 1kg per nested bag for extended use, rather more for short trips on good roads from the supermarket.
  Typical dimensions: w 160 l 320 h 350 (c. 18 litres) ...depending on how you fill the bag, which adjusts to contents.
  (B) Costs:
  Weight: c. 11g per bag
  Folded size: c. 20cc (various shapes), air excluded fairly well.
  Money: nil.
  Acquisition hassle: negligible.
  (C) Available colours/styles:
  Lots. For those who prefer not to advertise, many small shops use anonymous bags of this type, in various colours/designs.
  ... pretty hard to beat? OK, arguably it can look cheap...
  With apologies people who make or sell seat bags.
• mark james, Nov 1999:
  Have used a Super C saddlebag its fine you can fold the bike and leave the saddlebag on Make sure your saddle bag loops on your saddle are sturdy. Mine got broken by a baggage handler picking the bike up by the saddle bag. The seatpin is designed to take a big load so a saddlebag is fine. I do a have an uplift but I haven't fitted it yet heavy duty bit of kit.

Storage of emergency equipment inside the frame

• DRMLyons, Jul 1999:
  I keep a spare long cable in the top tube permanently. Does anyone else keep anything useful in their top tube?
• Marv Gozum, Jul 1999:
  Sounds like a custom slim case can be made for emergency supplies such as this brake cable, accessible only if the bike is folded .....
• Marv Gozum, Jul 1999:
  On the front half of the frame, the opening is large enough to not worry so much about reaching for objects, on the back half, there's only a tiny opening that dissappears into a void.

Baby-seats on a Brompton

• Immanuel Burton, Aug 1997:
  If the young child to be carried is small enough, then you could do what I once saw on a Brompton - the child was sitting sideways on the rear carrier, and as his legs were short enough, his feet did not drag along on the ground.
• Dave Horne, Aug 1997:
  I've only had my Brompton for about a month or so, but think it would be wiser to have the child (a small child) sit up front. Once I started from a complete stop (how else <g>), and the front end of the bike came up. I would bet that the center of gravity is well in the back of the bike and having a child in the front would make more sense and be a bit safer.
• Peter Amey, Aug 1997:
  [Issue 16] of the Folder from last year had details of a child set installation on a Brompton.
• Channell Wasson, Aug 1997:
  You could attach a third wheel set up to your Brompton to carry your precious one. Clamp it to seat pillar
• Custfold, Aug 1997:
  I have adapted a Dutch baby seat, designed for quick release from a frame mounted plate, to fit the Brompton front carrier.
  The frame mounted block (extra weight) is replaced with an adaptor to fit the Brompton block. The 15Kg proposed limit for front mounted child seats, is well withing the capacity of the Brompton block (IME I have exceeded this many times).
  We have tested the seat with a 56lb weight (25Kg) riding around farm tracks. On these tests the steering was noticably heavier, but not unpredictable. Andrew Holland has a first production model, and the price is currently coming in at #65.00, subject to the pound's fluctuations. The Holland family were trying out the prototype model at Weymouth in May, and apart from some retraining of the hand signalling assistant found the seat worked well.
  Mounting the load on the frame, and with main weight approximately over the front axle is almost identical in principle to the delivery/postal bike. The front block is designed to take extra load, and takes it low down, keeping c.g. and balance in trim.
  Other options with the unmodified version of the seat, are to mount it on the steering tube (facing forwards) - which so9me Dutch users claim is OK, or the seat post, as happens with conventional bikes. This latter is likely to foul the back of your thighs on a B, and put extra bending load onto the seatpost - see my notes on 'How I bent my seatpost' by 6'6" 200lb weakling. Both the last 2 also require a clamp fitting, and may affect folding.
  If demand is sufficient we may be able to get ther seats in kit form, rather than the tedious process of dismantling and converting the bracket, and reassembly. Bulk purchase may also help us to keep the costs down, and perhaps make the seat available directly from a local shop, rather than a special item.
  I'll put a photo in with the price lists which I've finally got finished, only to change again no doubt!
• David Hansen, Aug 1997:
  I have seen a rearward facing child seat attached to the front of a Brompton. I didn't look to see how it was fastened, but assume the post holding the seat was screwed onto the luggage mounting.
• Custfold, Nov 1997:
  The proprietor of Griffon Alternative Cycles noted to me that he'd seen 'competition' for the child seat on a Brompton design
  I saw a Brompton with a child seat a few days ago. It had long rails which ended in a large plastic clamp which fitted onto the seat tube.
  I'm wary of seats on Brompton Seatpost, due to the interference with folding (sliding post down) and extra moment loading on the seatpost which will thus bend more, potentially to deform permanently - loading the front block, designed, and IIRC tested to considerable loadings, with lower center of gravity is IMO (perhaps slightly biased) a better option.
• Custfold, Apr 1998:
  Drop me an sae and I'll send a picture of the seat made for Andrew Holland and others, it fits the front carrier block and is rated by the manufacturer for kids up to 15 Kg, we rode it with a 56lb (24Kg approx) weight in around farm tracks and it held up ok - but Brompton advised max weight for the block is 16Kg.
  The seat is a modified version of a Dutch seat which fits the front stem or rear of seatpost with a pair of prongs into a socket bolted onto the frame tubes - spare mounting brackets can be fitted to different bikes. I have one unmodified unit left at present.
  • Simon Risley, Nov 1998:
    I first came across the seat - an adaptation of a Dutch seat called a Bobike Mini - when I bumped into Andrew Holland and his son at London Zoo. Andrew kindly sent me details of how to get one, and I put in an order to Dave (his e-mail address is "custfold@aol.com").
    I have been very pleased with it and regularly use it to transport my two year old, Olivia, around London. She loves it. I have also - rather tentatively - taken my four year old out on the seat, too, but she is as tall as many six year olds, so I don't do it too often because of the heavy loading that it puts on the Brompton front carrier block.
    The seat is very dinky: it doesn't look at all out of proportion to the bike, but carries Olivia perfectly adequately. and is padded. I think that the rear-facing configuration is good from the point opf view of cutting down on the wind-chill factor and at the same time allowing the rider to interact with his/her child.
    The legs are adjustable to 3 different lengths, and there are neat elasticated foot-retaining straps.
    My only criticism is that the seat would be greatly improved if there was a headrest - particularly useful with smaller children whose necks aren't as strong as an adults. I've corresponded with Dave about this and he suggests a home made rest made with jubilee clips and a strip of neoprene or somesuch, but I'm not terribly enthused at its probable appearance! I would like to fax Bobike to see if they make a headrest, as the top of ythe seat has holes that would seem to indicate this as an option. However, I cannot get their fax number (it is on the seat itself but is unreadable on mine!) Any info on this gratefully received!
    If anyone would like to look at it - or would like any further information - just e-mail me on "simongikuk@aol.com" and I'll try and arrange a time. I live in Shepherd's Bush - which is W12, not W14 as stated on the Website.
  • Custfold, Nov 1998:
    Oh - I thought I'd suggested a sheet of clear Lexan with Bulldog Clips (Translation required here) which if fitted to the curve of the seat back would serve a double purpose as a clear fairing for the adult rider, at the same time. One drawbach though is that the seat does neatly sit over the folded Brompton (seat facing down) and a fairing (unless detachable) would make this too big for the folded package.
• Ruud H.G. van Tol, Apr 1998:
  How I did it in Amsterdam:
  Baby (I think she was about 3 weeks old): in a baby-carrier on my breast, baby's feet under my coat, its head (like yours) in the open air (important because you generate a lot of heat!), baby looking outwards.
  From when she was about 12 months: normally available child seat that fits into a block that I attached to my Brompton. The block looks a bit like (see below). It is 'U'-shaped, and quite strong, and wide enough to go around the big tube. The seat has pins that go into the holes. The block is available separately, so you can attach one to each bike you have.

• Channell Wasson, Jan 2000:
  Before I describe my child seat solution, I want to state that it is not an endorsed Brompton Solution. Use this suggestion at your own risk and peril. CAVEAT Brompton fan!
  I suggest using the Brompton basket mounted on Carrier Block with a couple of holes cut out of front of basket and then properly stiched and reinforced for comfort of the child. Then place padding under and at back of child. The kid rider loves being up front and there you can keep any eye on the little darling! For redundent safety measures place a strap through handle of basket and around handle bars in case carrier block starts to go. Don't try it over a 20 kg (40lb) load. A very unauthorized solution, but it has produced great joy for both riders--especially with our dog Bromie running along side. Shortly I will have photos of this solution in Current Events Photo Gallery on our Brompton web site.
• Custfold, Jan 2000:
  A2B issue14 deals pretty comprehensively with methods of conveying children, our Child seat conversion unit uses a proprietary model of child seat rated for children weighing up to 15Kg - This is modified to clip directly on to the front block, putting the child's weight in by far the most stable and least stressed position (on a seatpost the child seat will put weight outside the wheelbase of the bike (wheelies more likely - as experienced on Bickertons and Micros) and put extra loading on the seatpost to bend it rearwards, my 95KG plus small rucksack did this until I fitted thick wall s/s tube and built the first extending seatpost. The child will also get a very close view of the rider's rear end (the seats are usually set further back on conventional bikes) - The seatpost will also need to have the child seat fittings removed to fully fold the bike.
  Brompton used to suggest a maximum load of 16Kg on the front block but have downrated this to 10 Kg, This conservative figure reflects the problem with panniers which are loaded to provide large swinging moment forces on the 2, 4mm set screws which will loosen and occasionally shear if allowed to remain loose. I fit a secondary system to all my blocks which acts as an insurance, but when carrying children this way you are strongly advised to keep th block well secured.
• Hans Langen, Feb 2000:
  I used the childseat made by Dave Holland for about 1,5 years. It worked great! The child is sitting in front of you, facing you. So there is close contact and you can easily watch your child and talk to it. Because the seat is in a low position there is unrestricted view. The quick attachment to the front carrier block makes it very easy to fold the bike and enter a bus with child, seat and bike. I always felt very safe although it needs a bit of practice to get the child in the seat.
  Now he is too heavy (2,5 years / 17kg) and a trailer will be the next step (have not found the right one yet.....)

  It is a standard Dutch bicycle child's seat, takes children up to 15kg. The seat clips in to a holder, so you can still fold the bike by quickly sliding the seat out of the holder. (larger & other images)

Dave Holladay

I ride 100" fixed wheel on 27", and used to ride up to 128" including up moderate hills with a geared machine - I have sheared 4 TA cranks off at the axle socket in 15 years, and frequently fractured chainstays, seatstays - the only crank axle housing which has survived without 'belling out is the Nervex on the Scot, all others have to use cartridge bearings. [...] I broke an AW axle aged 14, and continue to bend all but the best quality solid rear axles, and break SA hollow, slotted ones. [...] My weight 95Kg - say 210lb, plus occasional 60lb pack, and up to 250lb on the trailer, and the front pannier......

My original 1989 front forks (about the only original bit on the bike) appear to have given up the ghost - I'm wary about riding it with the trailer (although the last trip -walked home with 70 sheets of hardboard (at least 150Kg)), once I get both brakes up to scratch. The problem is that the forks 'knock' from side to side, suggesting that the steerer has fractured and the steerer bolt & wedge are the only things holding the whole lot together. Not bad considering that I've seen out at least 3 sets of frame units (front/rear) and 4 or 5 rear triangles - interesting that the current rear triangles seem to be lasting with no problem, now the pivot spindle must be wearing more (going by the wear on previous exchanges).

I used to build 36 spoke 27" wheels in the 50 minute train trip between Edinburgh & Glasgow, and usually reckoned to fix a puncture in the 8 minutes between Paisley and Glasgow.

The main tube meets the rear wheel assembly (triangle), adorned with Dave's replacement suspension unit, retaining strap, and half of the skatewheel conversion kit. Also a Blackburn MP-4 pump fitted through Dave's adapter instead of the standard mini pump.

Hinge connecting the front wheel assembly (left) with the main tube (right) including Dave's clamp plate retaining kit to secure the plate and bolt (far right).

Nordlicht dynamo fitted on front fork, B&M Lumotec Plus front light, and V-brakes!

T-model rear rack with a B&M Toplight and a 4D-Lite Plus on the mudguard, and the other half of the skatewheel conversion kit (notice the alu extensions).

With Dave's custom carrier fitting to the standard Brompton luggage block, you can move a lot at once...

And since that's not enough, Dave is developing a trailer built around a waterproof box...

... or around a bike carrier. Notice the chopper handlebars on the black Brompton and a smaller custom version on the white Brompton. The black Brompton has two chainrings and a simple freewheel. The white one features an early version of the castor kit.

Shopkeeper to Dave's business partner: "Your husband will call in?" "Yes he's coming through on bus" "Oh but it's heavy, he'll need a car" "He'll decide when he arrives" At the shop: "Oh your wife said you'd be bringing a car" "I don't have a car and I don't have a wife." "How can you take the package?" "Just put it on the carrier" and leaves the bemused shopkeeper.

	One PC & 17" monitor. Note that the bike is now fully HS 33 hydraulic braked - nice daglo casting finishes. The led lumotec conversion is fitted in its wooden plate, as is a freecoaster hub (1-speed) and a SON 80 dynamo. First of 2 Secutec B&M experimentally mounted on rear rack stay. Note how using the Smartbox on rear kept heel clearance for my size 11's. Sorry about the pedals - need to get new set... Estimated GVW based on riding over weighbridge (digital 0kg-50,000kg) at Dover Eastern Docks with a similar load is c. 200kg including 100kg of me. Very smooth ride, no major problems apart from limited handlebar swing.
