Slack err no chain.

Slightly more information.

An internal hydraulic system that uses oil pumped through tubes in the frame to spin the back wheel? Sounds simple and easy to replace.

that's actually look quite good, althought I'm worried about the many hinges that could go wrong.

and the price, I'm willing to bet my testes that it will cost a grand easily.

might as well get a brompton, they're decent little bike.

Havent you already given one of your balls away?

A bike which can be folded completely into the space of the wheel's 26in circumference.

Techincally, it's not completely within the circumference, is it?

too many hinges, it must flex like a motherfucker.

It would take a month to work out how to fold it!

Remind me of when I picked up my first Brompton, the bloke showed me how it was done, I was like "errr, Ok", rode it back to work and spent 10 minutes outside trying to work it out.

hah! yeah it's the same here, after a while getting used to it, folding the Brompton become a piece of piss, in fact it only take a few twist and turn to fold it.

it's lugging the folded brompton around that make it a bit of a drag.

Sorry to derail the OP slightly but reading the stolen bike thread is so depressing - I'm now being put off cycling at all to locations where I know I'll need to leave my bike out of site for a while... and am becoming strangely drawn towards the unknown terrors of the folding bike!

I'm getting sorely tempted to go down the Brompton route for such occasions. Does anyone use one on a regular basis and find that it's a viable alternative to their normal whip over 15+ miles?

Unfortunately I can't shake the impression they'd make for a pretty frustrating (and, if I'm honest, slightly embarrassing) ride...?

talk to Sam

he uses a brompton for distances
