I got the hall sensor wires worked out– the +5v wire was rubbing against a sharp part and actually got cut. I fixed it and the bike worked. I took it to work and to the San Jose EAA meeting and everyone took turns riding it and then going 2-up. Initial results are very promising: the suspension works great, even with two riders weighing 350-400lbs total the ride is very good. Acceleration, especially up hill at the low end, however, is poor. I’m not sure why it’s as bad as it is because the previous version worked quite well in San Francisco. Is the bike that much heavier now? Could there be some mechanical drag like the coaster brake engaged on partially? Or is it due to the hall sensor wiring?
