Electrical parts on this list must match this exact model, and they are fitted at the external plugs or by a pro. Never open the battery, controller, motor or display. For battery and charger trouble, start with battery won't charge and e-bike battery care.

The RadTrike has a parking brake that also cuts motor power while it is set (see the RadTrike tech overview). Never disable or work around it. If the trike will not move, check that the parking brake is fully released before anything else.
