That's basically what most brushed DC motor controllers do.

I guess some things never change

... and they have endless perpetual motion threads there too.

I'm curious about the lack of BLDC motors in this size range. They seem simpler than brushed DC motors, but the big ones available are frighteningly expensive. The Controllers for them are expensive too.
I need to re-check but I don't think either Brammo, or the other one (Zerocycle?) are using brushless. Kinda' makes you go hmmmmmmm.
Please don't tell Mom I'm a pilot. She thinks I play piano in a whorehouse.
