🔧 Important Notice: Rear Light Compatibility with Lock Controllers

Please be aware that the type of rear light used on your e-bike is directly determined by the model of the controller with lock.

To avoid wiring issues or incorrect connections, make sure to confirm the exact model of you controller with lock and match it with the correct rear light version.

🔐 Controller with Lock Compatibility Overview:

All controller with lock are compatible with wiring harnesses with lock.
(In other words, if your e-bike uses a Half twist throttle with a key E-bike  ignition, it is compatible with all controllers with lock listed below.)
