You can get it with 500w, 750w or 1000w. I’d do 750w, more than enough for a road bike. I’d be more interested if the bike had a larger battery, say a min of 17ah. Not sure I’d want dual batteries as it would add too much weight.This is a neat bike, but what I would really like is an uber-stealthy road bike, maybe with less power for exercise purposes and not to overpower skinny tires.
