Restore the brain and power distribution of your Duotts C29 electric mountain bike with this original 48V 750W Ebike Controller. As the central motherboard of the vehicle, the controller regulates everything from throttle response and pedal assist algorithms to battery cutoff safety. If your ebike suddenly refuses to power on, displays a persistent communication error code, or experiences dead throttle response despite a fully charged battery, a fried or water-damaged controller is almost always the culprit.
Manufactured to the exact factory specifications of the Duotts C29 750W powertrain, this heavy-duty brushless motor controller serves as a reliable, direct drop-in replacement part. It features a rugged aluminum grooved shell that provides passive heat dissipation, protecting the internal MOSFETs from overheating under heavy climbing loads. Pre-wired with standard color-coded waterproof connectors, this essential item belongs in the inventory of every ebike repair shop and regional distributor looking for high-demand electric bike spare parts.
