Bromptons are great - no doubt. I like them. I have a bike built by Flamingobike (Grace Gallant corp). It is also pretty good, is a copy of the bike you want, and is probably available in Taiwan for about a third of what you'll pay for a Brompton. You can have one with three or seven speed hubs.


Three speed:



Seven speed:



These have a differently designed frame to the one I have from them which is tubular like the B, but the general quality of the bikes is pretty good for the money. Mine has seen a lot of use and is very reliable and folds exactly the same as the B.
