For easy week-end getaways by train, I'd like to buy a bike with 26" wheels with a frame that can be easily taken apart (I'll also need a rear-rack and mudguards that can be easily removed, but that's for another thread). I tried a foldable bike with 20" wheels, and frankly, I was already sore the second day :-/
I did some research: Considering the prices for regular bikes, I was wondering if it'd be more interesting to get those and ask someone to cut the frame and add an S&S ("S and S Coupling a.k.a. Bicycle Torque Coupling (BTC)"):
If you have good experience with that kind of thing, what do you think? If that doesn't sound like a good idea, I guess I'll take a deeper look at collapsible bikes (is this the right expression?) from Montague, Dahon, etc.
