Your bike and that reduction unit are sexy!
I have a mongoose blackcomb which is the same as one of doctorbass's bkes. I am going to talk to methods about hooking me up with a rear 9 26" 9c and the works. Just quick, what size controller should I look for with a 26" 9c@44.4v? Is a turnigy Watt meter and a gps good enough or should I go for the CA?
