GOOD MATERIAL:The Motor Brushed Speed Controller’s shell is made of aluminium alloy with groove design, which can protect the inner circuit and good for heat dissipation to avoid thermal overloading.
THROTTLE TWIST GRIP INSTALLATION INSTRUCTIONS: If you encounter a plug mismatch, you need to wire it in a straight line, wrap it with insulating tape, and then turn it on. This model has 5 wires for speed control and electric door lock function. Some original electric bicycles are connected to the circuit board. Please do not connect directly. It needs to be directly connected to the controller handlebar wire.
