Brandon Lewis –
My controller failed after about a year. Every listing on Amazon looked different and nobody could confirm compatibility. Customer support here asked for pictures of my controller and connector before shipping. Installed it in about 20 minutes and my bike came back to life.
Lance R –
It was easy to order, and it works perfectly. I would have given 5 stars but when it arrived it had no protection, it was just the box and the controller. Was a bit confusing with the wiring but the photos helped a lot. The service was great, they responded within a day or less.

Works great, would be 5 stars if I arrived with protection. Service was great, and they responded quickly. The photos helped a ton. Will order from here again.
Mike R –
Controller arrived exactly as described and plugged right in. Customer support helped me verify the version before ordering. If you’re rebuilding a Ridstar Q20, this is probably one of the few stores I’ve found that carries nearly every replacement part instead of just random accessories.
