This took about a week to convert from one electric motor powered YZ to a QS V3 motor and Votol EM260 Controller electric dirt bike. I used the battery and power wiring from the previous build, that made it easier. But the Motor, controller, wiring harness, and programming were all done by ElectroandCompany.com. Make the mounts , plug it together, a little plastic added back on and drive it away. I weighed the bike 103lbs front wheel, 118lbs rear wheel.
