Hi everyone,

I posted a similar thing on the bike mechanics section of this forum but thought I should ask the people who really deal with this stuff.

I'm working on a design for a new folding urban/light trail bike. Part of the design necessitates an upper frame that is made from two pieces, meaning that the minimum clearance between your knees (when pedalling) will be about 140mm, give or take a few mm.

Is that something you think you could tolerate? If it meant you could have a light, strong full size folder with full size wheels that folds into a space the size of a trekking backback?

All comments and opinions very much appreciated

cheers

Tom
