"Holy Cow Bikeman, look at all these replies!!!"
I haven't been back to this thread since I posted it back in Oct., & I didn't realize that folks would be replying. Oops! Originally I was calling around Tucson looking for a gas bike to buy. In the course of the search I hit a place with ebikes for sale. I got one & it's new & pretty & I really like it, except for the very limited range imposed by the battery. (12-18mi) Sooo I started looking for an engine kit for the Hard Rock 21 spd I've had for coupla years. I found one, married the two & the result is old & rode hard, & sportin' this tiny engine she sure ain't pretty, & I love it!!!! On both bikes I use the motors to help me pedal. I'm old & fat & I need the excercise! I got a route west on Speedway from Kolb to Columbus, down Columbus to Pima & back up Pima to Kolb & home. I try to ride it at least once a day & it's really helping my legs. Once in a while I'll just let the motors do the work, but I try to keep it to a minimum.
