Anyone try one of these bikes? This woman set a record on one:

It is a very interesting design, and you can buy the bike as is, or buy a conversion kit. With the conversion kit, you buy a Walmart bike, and convert it to a Cruzbike. It is a very clever design.

It is a FWD (forward wheel drive bike). All the gears are on the front!
