a brompton wheel might be your best bet. oddly enough, they're not free:

Little wheels with big prices!

I have gone for the BSR 3-speed version, which I found second-hand.

So now almost all the components (wheels, tyres, brakes) for what we hope will be a 'super Bickerton' are either here or on their way! Woo hoo! Let us pray that most of it fits

A friend of mine is into Bikertons and has 4 and half of them, 2 of which are the country model. Apparently the main frame hinge is a weakness and has a tendency to break. I rode one once and it was better than I expected so with good tyres should be a fun bike to ride.

From Derek Baker's site (http://www.bickertonbicyclespareparts.co.uk) I was able to learn that mine is a MKIII model. The hinges on the various 'marks' are all different and I believe the bikes became slightly heavier and stable over the course of their development. This might explain the varying experiences riders have had of Bickertons.

It is a superlight construction and not something you'd pile masses of cargo onto, but my feeling is that it scoots forward before it flexes.

I love the advert.

Its looks like a great bike to play around with. The updated parts you are installing will be really interesting to see and I can't wait to hear about its ride

PS Derek's website is a wonderful piece of history. Good on him for trying to preserve the bike.

Should be an H3111 or similar, almost identical to the recently discontinued SRAM T3. Very easy to disassemble. Clean it and lube it.

Hey man, I love my Bickerton, its treated me well for a good while now. I ride it to the flea markets on the weekends, and if the streets of Philly havn't killed it yet nothing will.

Not sure of its age, it has a Sachs 3-speed hub and the American-style brace on the handlebar. A little tatty but complete and technically OK. Seller threw in an extra frame with headset, chainset, front and rear wheels with tyres, and a bunch of inner tubes.

A quite astonishing construction and feather light. Folds down as small as a Brommie in about ninety minutes... The kickstand (or kickwire?) in particular is a masterpiece of minimalist lightweight engineering.

The grand old Union ratrap pedals are non-folding, so short of carrying a spanner I think I will need to replace these.

Any ideas for a sympathetic restoration/tuning gratefully received. I will be changing the saddle (maybe to a B17?) and it will need battery lights (strictly speaking verboten here but I'll risk it) in a suitable style.
The frame can be folded easliy in less than a minute and the Bickerton does/did come with a "quick release" type pedal. I have a generator powered front and rear light on mine, Im not 100% sure but I think you may have the Australian made version.

Great to see another Bickerton. The Brooks saddle goes well with it.

Made in Welwyn Garden City according to the stickers - so UK it is. The rattrap pedals, unfortunately, were not QR on the left - however, they were nice classic pedals and now grace my winter folder. The Bickerton got its foldable pedals, they're lighter and improve folding.
Dynamo lighting would be perfectly possible, mine obviously had a bottle dynamo fitted once (I can see where it was bolted on). I'm going the battery route to keep everything simple and lightweight. I'm enjoying having an ultralight folder that sits in the footwell of the car for impromptu spins.

An attempt to cash in on retro ?

Stock Tern frame silver color, Brooks saddle/cork grips.....

Actually a little more searching I found this.

http://www.bickertonportables.co.uk/

Seems the designer's relatives are using the Bickerton name on Tern frames ?

A technical update:

The good news is that a 305mm/16" Dahon wheel fits just fine in the front - and there is still enough clearance for the mudguard (17mm between tyre and fork crown - and just enough clearance between the stays for a 40mm Marathon). In fact it is so similar in size to the old wheel, even the brake blocks needn't really even be adjusted.

The Miche brakes I ordered (57mm drop) are sadly just too short - by pulling in the rear wheel closer and shortening the chain they would just work, but they won't reach in the front. Another genius moment...

Tiagra brake levers are here too but they will necessitate removing the grips first

I should have the Brompton rear wheel next week and by then most of the various bits and bobs should have arrived too (allen-key front quick release skewer, Sturmey SLS thumbshifter, nuts, indicator chain and rear sprocket).

front wheel:


not so good; clearance frame/rear stays


on a lighter note - swish USB lighting!


pretty, but impractical - rear brake fitted


USB front light, Tiagra lever on the floor:

Looking great. I love the look of Kojaks without mudguards but alas just not practical on my daily commute in the UK

I find it very annoying when stuff like this happens. It's one thing if there was a gradual progression or improvement in design over the years that resulted in the latest offering but to take the Bickerton name and slap it on a bike that has nothing in common with any of the previous Bickerton models and call it a 40th anniversary edition is flat out lame.

what's implied, it seems to me, is the idea that, had the ingenuity and brilliance of the bickerton line continued, it would have arrived at the "tern design solution". a goofy and illogical conceit, surely.

Taking a cue from the car industry really (Mini, MG, Fiat 500 et al.). Hi-Fi firms have been up to this sort of thing as well. Use a prestigious name, stick on a couple of expensive looking bits, run it up the flagpole and see who salutes.

Obviously the 'successor' to the Bickerton was the Brompton - made in the UK, quite a few of the parts are the same and the folded dimensions are similar.

On Ebay today you could buy two for 75. Put mildly, that is rather a good buy considering folded size, weight and (yes) ride quality.

Yes I thought that too having done a quick look there. Some are selling "as new" for 399 though!

I am tempted to try one but I have tried enough folders now I think to know that for my purposes the Brompton is still a 90% fit.

My other folders make up the 10% and keep me occupied with all thing bikes.

One day I'll have to test a Brompton to compare. I wouldn't have any qualms about a 16" wheeler as a runabout, that I have learned.

Things are still taking shape on the Bickerton project - everything on hand now except for the Sturmey Archer gear cable anchorage (there's always something, isn't there?) which I had to order from the UK.

The Brompton 3-speed rear wheel is a perfect fit for the Bickerton and almost half a pound lighter than the old wheel too.

how's the progress, elvis?

also, awhile back we were discussing the 40th anniversary bickerton and possible authentic successors. i saw the "morabike" and thought it should be considered a contender. definitely a few interesting design details (rear elastomer suspension; stainless steel frame) and some similarities:
