The bike's real innovation is the Continuously Variable Transmission (CVT). Just like an internally geared hub, the CVT system can be shifted under load, while stationary, and even while back pedaling. The difference with CVT though is that if you run a non-indexed shifter there are no 'set gears' and no indexing. You can have any gear ratio you want between two set limits. Hopefully this thing hits the ground running because it has so much potential.
