Using your Bafang Rm G060 motor is easy. First, make sure it's correctly installed on your 20'' bike with the right width of 175mm. Connect it to a 500W rated controller as required. If you're using it on a rear wheel, it works great with a 7 - speed Shimano cassette. For front - wheel dual motors, it doesn't need a cassette. When riding, enjoy the enhanced comfort and power it provides, especially on fat tyre beach or snow bikes. Here are some important notes. Don't use it with a controller that's not rated at 500W, as this could damage the motor. Also, keep it away from excessive moisture. For maintenance, regularly check the connections to make sure they're tight. Clean the motor gently with a dry cloth. If you notice any strange noises or performance issues, stop using it and have it checked by a professional.
