Swap out a damaged, worn, or burnt-out drivetrain with the genuine OEM Happyrun Tank G100 2000W Hub Motor. This heavy-duty brushless rear wheel motor comes pre-wired and ready to drop into your existing 20-inch fat tire rear dropout configuration, restoring your e-bike’s factory-spec climbing torque and top speed performance.
Core Benefits:
-
Genuine Factory Match: Direct drop-in component that interfaces perfectly with your stock Happyrun 48V controller layout and display system.
-
High-Torque Performance: Delivers up to 95 N.m of rotational torque to handle steep 30° hill climbs and maintain stable high speeds.
-
Plug-and-Play Quick Disconnect: Includes the waterproof main power loom connector for simple, tool-free line disconnects during tire or tube swaps.
-
Heavy-Duty Internal Gearing: Sealed, weather-resistant outer casing protects internal high-temperature copper windings from rain, dust, and sand intrusion.
Strict Compatibility Note:
This motor is explicitly wound and rated for the standard 48V Happyrun Tank G100 system (2000W Peak). It will not work as a direct factory replacement for the high-voltage 72V Tank G100 Pro model (which uses a completely different 3000W/6000W motor casing and controller architecture).
