Before shipping they confirmed my motor serial code. That gave me confidence I wasn’t wasting money on the wrong part. Everything worked perfectly.
Brandon F –
My rear hub motor failed after about 1,500 miles. Ridstar wouldn’t sell me a replacement because I didn’t purchase directly from them, and the Amazon seller had no stock. Thankfully I found this store. They matched my motor serial number and sent the correct one. I also noticed they stock controllers, throttles, chargers, wheel axles, and other Ridstar parts. Great resource for anyone keeping a Q20 running.

My Q20 was purchased on Amazon. When the rear hub motor failed, Ridstar told me they only provide motor support for bikes purchased from their own online store. I couldn’t find one anywhere until I found this website. Motor fit perfectly.
