Genuine Bafang Internals: Delivers a reliable 750W rated output and a peak torque of up to 65Nm, perfectly synchronized with the Duotts C29's factory controller algorithms.
Cost-Efficient Core Design: Avoid the hassle of rebuilding wheel rims. This stator-and-gear assembly drops right into your existing 29-inch wheel motor casing, minimizing repair time.
Pre-Installed Planetary Gears: Features hardened, wear-resistant internal gears designed to optimize power transmission and resist stripping under heavy acceleration.
OEM 9-Pin Waterproof Plug: Equipped with the factory-correct 9-pin wiring harness, ensuring clear signals for the three heavy phase wires and five hall sensors without manual wire crimping.
Durable Electrical Insulation: High-grade varnish insulation on the copper coils protects the motor internals against internal condensation and short-circuits, expanding your stock of electric bike spare parts.
Q1: Does this listing include the tire, spokes, or the outer metal hub shell?A: No. This product is the Internal Motor Core assembly only (consisting of the internal axle, stator windings, copper coils, magnets, and planetary gears). It does not include the outer wheel casing, spokes, rim, or tire. It is designed to slide directly into your existing Duotts C29 wheel shell.
Q2: How can I verify if my original motor core is the component that failed?A: If your LCD display shows a motor fault code (such as Error 07), or if the rear wheel feels heavily resisted or "notchy" when turned by hand while the e-bike is turned completely off, the internal magnets are melted or the phase wires have shorted inside the core.
Q3: Can this 750W core be used to upgrade the 250W European version of the C29?A: While the physical frame dropouts may accept the axle spacing, running a 750W core requires a corresponding 48V controller and battery capable of delivering the necessary amperage. For safety and performance reasons, this is recommended strictly as a direct replacement for the standard 750W model.
