I got this Razor as a totally stripped double dare. I ordered this kit and it shipped to me in a few days. As you can see it took a bit to fit the motor. Instead of making an offset plate I used some spacers to move the brake caliper out and by flipping the brake hub. I sandwiched the old sprocket and new 80 tooth sprocket on the other hub. 4 well placed holes in the existing swing arm with some stand offs and it was set. The chain was the worse part, I think eventually I will look into switching to a heavier chain.My only complaint so far is that the motor case was a bit rusty, but nothing that stopped me from proceeding. It only cost one star....Even with the small batteries this thing moved me around. I'm currently on the fence with going lithium or lead/acid batteries, my friends ebike batteries did not have the discharge capacity to make this run to spec.I'd recommend this kit for someone that wants to take a crack at the electric powered vehicles.
