Donor bike is Haro V2, 6061 aluminum, with Rapid Rise shifter. Battery mounted on the seat stays.
I like this bike more than just about anything. It's just fine for large items, like construction lumber and tools. With great gears, big bags,Bionx power, it's a smooth ride, not bad in winter, either. In "regen" mode, the back wheel drags, similar to ABS with straight line directional control, so riding on ice and snow is tighter. With 4000 miles on the gears and chain, I'd say the Bionx is helping save the transmission as well.
