I was wondering if there is any system, that has a motor and battery all integrated into the front wheel. I would like to be able to quickly swap the front wheel, so I could add the electric wheel when I feel like riding electric or not. Don't really need huge range or power(200 watt should be sufficient), as I'll prolly just use it to assist in hill climbs so as to not to sweat on way to work.
Does anyone know of such a system, or something that can be easily converted in under a minute.
I've noticed a few options so far.
First is Vivax assist, its actually integrated into the frame, but the penalty is only 2lbs, but it costs 2k right now, which I feel is too expensive.
