I bought a used TurboAnt M10 relativity fast 19-20 mph top speed, for 27 lbs and I paid $190. Not 45-60 mph like those high end electric scooters but its 27 lbs which make it easier to lug thru the subway and trains. It looks very generic like every other maker of the low end scooter change some colors and slap their logos on it. I am wondering if the parts are interchanged GoTrax, Inmotion or whatever under $500 Electric scooter. TurboAnt comes standard 500 watt motor which is great, but I don't think the controller has regen. Should I put in a another controller supports regen ability and support front motor? When I hit the power, if I'm not positioned right the front part of the scooter does lift up a little. Sure it would add some weight but at least I can push pass 20 mph if I need it. Lastly, any kits to add lights on the stem and board, similar to the higher end scooters. Reason I didn't one of those because they weight easily 60 lbs or more.
