I overvolted my scooter to 36v. The stock motor was not performing very well and was making an electrical burning smell. I decided I needed a bigger motor. After some "YouTube research" I decided on this one. This scooter is so much more fun to ride with the new 500w motor! It's bigger than I expected and took some work to get in place. The torque is nice, and now I can reach 24 mph easily. I plan to buy this same motor for other projects soon! I was offered compensation for my honest review. SG.
