Thanks Snowsurfer. Your comments re torque arms make sense. But just so I'm clear, in the context of this thread, is the crescent wrench meant to act as a torque arm?

Also, re your comment "16mph is EXPECTED at 36V", I guess I don't feel so slow. "Reaching" 20mph (and slightly above) is no problem. But "averaging" 20mph in city riding seems very fast to me.
