RANS makes a line of crank-forward bikes. The frame geometry allows the rider to sit back more (on a comfier seat) but ride like a normal two-wheeled bicycle. It's hard to explain, so please see the attached image if you don't know what I'm talking about.
Anyways... I'm not quite sure how to describe this thing. It's like the perfect marriage between a recumbent and a road bike. It's lightweight and very fast, yet extremely comfortable, even for long rides. Heck, it even climbs well! Does anyone else ride one of these amazing machines?
