Default Re: Need some advice

How steep are the hills where you live? At your weight on flat ground with a 30 cc engine it's going to need 25:1 reduction to propel the bike. You'll even have to pedal assist it. If you have steep hills then a shift kit is going to be needed. I'd say you'd need at least a 60:1 reduction in the low gear. The electric hub will really help if you add it.

I'm 250 lbs use a 33 cc engine with a shift kit. The reduction range is 49.21-18.82:1. I have to pedal assist on hills steeper than a 20% grade.
