Well what I was thinking is having an assist on my bike but only using it for hills and such on my long rides. So, with it off is it harder to pedal? Can the system be shut on and off without and problems? If thE system is on but I don't pull the throttle At all does it use much battery? How much assist would it have going up a hill? Could it pull itself? I'm about 160lbs.

Thanks for the responses.
