Re: Need help with first build
Welcome to the forum.
Your weight won't be a problem. There are members here that out weigh you, by a lot. Gearing will make a difference. Gear low (bigger sprocket on rear wheel) for hills. Gear higher (smaller sprocket) for flat terrain.
These are not motorcycles so be prepared to pedal assist on take offs from a dead stop and up steep hills.
Good luck, have fun and ride safe.
