I was going to be dismissive and state something like if you put a fiat 500 badge on a front wheel drive,1000cc front engine car it does not make it a rear engined rear wheeled 500cc classic.
Simular for a mini ad nursa.

Yes I have heard of progress! I sometimes whis marketing people sometimes had oringinal ideas
Anyway the actuall bike looks promissing.
Its not a bickerton that's just silly.
Reminds me of a bike friday tikit in the fold.
?

You have done an excellent job on that!

Love the radial front spoking, a must on all front small wheels IMHO.

Alas in the UK we would have to add mud guards

In northernmost Germany too I'm afraid. But we are having a spell of good weather. The original chromoplastic mudguards are due for a respray in either matte black or chrome - undecided yet.

Thanks for the complements too - makes it even more worthwhile

Just a few more comments of a technical and practical nature for any one interested in a Bickerton or a similar project.

The Brompton rear wheel (for the Bickerton's 120mm dropouts) is the way to go - use the Brompton hardware (bolts, washers) etc for a perfect fit. SJS Cycles in the UK is invaluable for all these bits and bobs.

A Dahon 305 wheel is an inexpensive upgrade for any Bickerton (with its 80mm front fork dropouts) and fits straight out of the box. I used a Brompton allen-key quick release which is lower profile than Dahons.

The Sturmey-Archer SRF3 hub shifts smoothly and fast, also when pedalling. The Sturmey thumbshift is particularly beautifully finished - it is indexed (but not marked, and why should it be?) and works either indexed or as a friction shifter. I did think about getting the - to my eye - more nostalgic bar-end shifter. Perhaps I will one day, it's an inexpensive part.

I kept the high gearing of the original Bickerton with a 13 tooth sprocket. This is no slow bike

Not much more to be said about the new Schwalbe tyres - they just don't make a bad tyre. The Kojak rear is inflated to 70 psi/5 bar, the Marathon Racer in front to 60 psi/4 bar.

I popped the Selle Contour saddle off my winter folder onto the Bickerton and find it a little more in character. I think it will end up with a honey coloured B17 at some point.

The cheesy Union Jack decals came from an outfit called 'I Say Ding Dong' - they have some wonderful stuff, mostly vintage motorsport related.


As far as luggage goes the Bickerton has turned out to be a little more versatile than one might expect - in addition to the 'traditional' giant blue bag (this can be rolled up neatly and small and clipped on) the hooks can take any manner of bags, notably any standard handlebar bag. Ortlieb Front Rollers also clip on neatly to the crossbrace - you could carry two, one in front, one behind the bar.

Bickertonia of historical interest:

Christian Miller's classic 'Daisy, Daisy: A Journey Across America on a Bicycle' - Daisy the Bickerton aside, a gread read if you enjoy travel or bicycle touring accounts.

Richard Ballantyne's 'Richard's Bicycle Book' has a few pages eulogizing the Bickerton too

This has all of course been done years before without anyone making a song and dance on the internet about it...

http://www.velovision.com/storyimage...5bickerton.jpg

'The Paul Stobbs Bickerton started out as a single speed which Paul adapted by widening the chain/seat stays so he could install a 349 16 inch wheel with an 8-speed derailleur ... The front wheel is also not original - it is slightly larger than the original but i cannot remember the size - but it takes a better tyre than is available for the original.'

Elvis, good work there, I like the idea of modernising the bike and making it more usable for every day use. Just read your last post on the folders in the wild thread and followed the link to the Japanese Bickerton blog. The photos of the Bickerton next to Brompton are very interesting and show just how compact the Bickerton is when folded, no bigger than the Brompton.

The photo next to the wheel arch of an Opel Astra shows the size quite well. Bickerton used to advertise 30" x 20" x 10". Since I'm planning on flying with the bike next year and measured up with a view to a hardcase, it came to 70 x 55 x 22 cm (28" x 22" x 9" approx.) - the less voluminous saddle, updated brake levers, and the folding pedals help to reduce the size a bit.

Nowhere near as convenient to fold though - five tiny quick release levers involved, you need plenty space to brace yourself against the bike when folding down the bars, and there's an odd looking little dance involved when wiggling off the saddle. Lots of sharp edges just at shin height to look out for. And since there is no mechanism to keep the bike closed (on mine at least) you need a short strap to secure everything together. Out of respect for its age I'm not constantly folding and unfolding though - weight and short wheelbase means it's usually easy enough to sling in the car or carry inside as it is.

Have the upgrades made any difference to the weight of the bike?

Not sure, I should have done more weighing! Modern tyres are lighter, the original saddle is a humungous heavy steel sprung affair, the old steel rat trap pedals were also heavy.

The new wheels are slightly lighter, although the originals aren't particularly heavy either (due to small size), modern brakes are slightly heavier than the 1980s ones.

I think the present incarnation weighs in at just under 22 lbs / 10 kg - with lights, handlebar bag and full toolkit - so probably around 20-21 lbs 'naked'. Not sure what the original spec 3-speed MKIII was. 25 lbs maybe?

If weight was the prime consideration there's plenty potential.

Yes, just imagine how much weight could be saved by replacing all those nuts and bolts with Titanium ;o)

I just inherited a Bickerton from a good friend. Currently it weighs 10.5kg in standard form. Plan is for it to be a light weight compact folder for occasional use. I have a spare Mezzo rear wheel with 4 speed Nexus hub which will probably find its way onto the bike. The rear drop-out spacing will need to be increased to 135mm but I don't think the stays will put up much resistance. The frame hinge is bent so that will need looking before I do anything else with it.

Sad to hear the hinge is bent . I should have though that the frame would bend long before the steel hinge. The parts should be available from Poole Bay Folders though. The different hinges (MKI thru III) can be seen on one of their pics here: http://tinyurl.com/hingepic

The biggest weight saving must be swapping that standard bar stool of a saddle (mine must have weighed a pound and a half) for something more suitable.

The rear triangle is surprisingly stiff despite the thin tubing - but a wider brake bridge should be an easy part to make if needed.

The Dahon rear wheel is a bit smaller than the Bickerton's 349, isn't it? Probably worth checking the brakes have sufficient reach.

Keep us updated, and do let me know if you need any parts.

10.5 kg is very light to start with. But saddle, wheels, pedals alone are potentially 2 lbs to save without trying too hard. And you can always remove the mudguards

There is a point when it doesn't really matter too much. You can carry a folded Bickerton around with two fingers.

Thanks for the link Elvis, my friend told me the information was the Pool Bay web site but I couldn't find it. I think someone who was too heavy for the bike had ridden it and went over a bump causing the damage. I think there are wooden inserts in the ends of the main frame that prevented it from being damaged. I have the Mk2 hinge and managed to remove it this evening and tried to straiten it out a bit, the clamp was bent as well, it's still not quite right. I plan to make a new and more substantial hinge and bracket machined from a solid lump of aluminium.
The Mezzo wheel is 349, the tyre on the Bickerton says its 349 so it should fit. Which of the Dahon front wheels did you use in the end?
In current form the Bickerton is nearly 2 kg lighter than the Mezzo although it is a very modified Mezzo. I live in the UK so the mud guards will stay on the bike

This one (Curve XL): http://www.evanscycles.com/products/...wheel-ec047434

No skewer supplied. I ordered Dahon and Brompton allen key skewers from SJS cycles and ended up using the Brommie skewer (less bulky, and not as blingy as the Dahon one).

The old inner tube was fine with the new tyre.

We usually have your weather, just a day later. I just use another bike. Mudguards will have to go back on soon enough - although I would like narrower ones than the standard guards.

Restoration tip: Bickerton mudguards turn out spick and span after a turn in the dishwasher!

Thanks for the info about the wheel Elvis. I will have a good look at those on the Evans web site, they have branch only a few miles from me.
I have hear stories of all kinds of classic carts being cleaned in the dishwasher but never cycle mud guards.
For last 6 months we seem to get the weather from Siberia, just a day later

The Pool Bay Folders Site has had a few updates and I noticed this single wheel trailer that has been made from a Bickerton. Unfortunately the photo is a bit small so its not easy to seethe detail but I thinks its a great idea.
