His cadence is very high, yes. Not so much a trick as a
endurance issue. Smaller radius cranksets seem to help this, as
a study in Bicycling magazine bore out.
Not so long ago, a 'bio-energetic' crankset was designed by
Shimano, and they called it Bio-pace, which had non-circular
gears. One can see a relatively exaggerated form of this system
in some gym equipment. The attempt was to use the different
forces that the legs generate as they push and pull on the
pedals. (In serious cycling, the feet are attached to the pedals
via straps, cleats, or some other fastening system, and both
downstroke and upstroke count.) Bio-Pace was, however, not to
prove a popular option- people complained about the 'strange'
feeling it gave them.
Circles are good things.
