Using your Ampd Ace Electric Bike Controller Module is straightforward. First, make sure your bike is within the compatible range of production dates (between 08/2020 and 09/2021 with a 3 - way light switch). If you're not sure, reach out to our team. When installing, follow the instructions carefully to avoid any issues. Incorrect installation can void the warranty. After installation, you can enjoy the smooth power delivery of the 48V 18A rating. To maintain it, keep it dry thanks to the waterproof connectors. If your bike has any changes or if you encounter problems, always consult us before making adjustments. Remember, using it on the wrong bike model or brand can lead to compatibility issues and loss of warranty.
