IMO with a 250kv outrunner you should go for a 24v setup. 9k rpm on a 25-30lb bike with a 150? lb rider will be a but much for the motor. What batteries will you run? I'd think that anything except lipo or a123 won't keep up with the amp spikes on the motor. Your reduction sounds right to me, but I've also been trying to figure out how to add gear ratios. Are you going to mount the motor on the downtube or on a bike rack on the rear?
