Here are a few concept bikes that I’ve come across lately.
“The Dutchess”, a prototype for Cannondale for a city commuter. The attention to detail is just amazing.
MIT’s motorized bicycle (give it a read before you go making wild assumptions).
Cheers!
24-year old Dominic Hargreaves came up with a pretty cool foldable bike. It looks to be a prototype as I don’t see a chain or drive shaft. (see skynews article)
The folded size is pretty small, and the design is pretty sleek. Looking at the couplers he uses in this bike reminds me of these Torque Couplers I looked a long time ago to retrofit into a normal bike: http://www.sandsmachine.com/
By the way check out the Folding Bicycle FAQ written by Steven M. Scharf – it is quite a few years old it seems but it is a good starting point.
