Impressive but cans someone enlighten me on why the ramped cog sizes?
I just cannot get my heaed around the drive train configuration.


It looks like each crank drives a chainring of equal size on the crank
behind it so each rider will pedal with the same cadence. The gearing of the
bike is the "huge" rear chainring onto the rear hub sproket.
I suppose with 10 pairs of legs, pushing such a gear is pretty reasonable.
