Q&A
Q: Why do I need to provide a photo of the controller label?
A: Since many buyers are unfamiliar with controllers, we need to verify the correct product purchase based on the original controller label photo. This prevents wasted time and money for buyers.
Q: Can I use your controller if my model differs from yours?
A: Different controller models use different communication protocols. Replacement is possible only if the communication protocols match. Typically, e-bike controllers consist of connectors for the power supply, motor Hall sensor wires, brakes, throttle grip, pedal assist sensor, bike headlight, and motor. As long as you can modify the controller connectors (we can assist with this modification), our controller can replace your original one.
Q: How do I find my controller model if I don't know it?
A: Send photos of the controller label and display screen serial number to our online customer service. We'll identify your controller model and recommend a suitable replacement.
Q: Do you accept returns if the controller is incompatible?
A: If you communicated with us before purchase, we accept returns and refunds. If you did not contact us before or after purchase and did not respond to our emails, we assume the controller model you purchased is correct and you accept our no-return policy.
