Wheel hub motor assembly;D28E;

The D28E wheel hub motor assembly is a self-contained propulsion unit that brings electric drive directly to the wheel. Engineered for DIY electric builds and retrofit conversions, this in-wheel motor pairs clean wiring with reliable performance, turning a standard wheel into a compact, drive-ready hub.

Smart, streamlined propulsion for modern rides

With the motor housed inside the wheel, there are fewer external components to mount or align. This means quicker installations, fewer potential failure points, and a tidier setup that preserves the frame’s lines. The sealed housing shields sensitive parts from road dust and moisture, keeping performance consistent across seasons.

Key benefits at a glance

• In-wheel propulsion: drive power is integrated into the wheel hub, eliminating chain or belt drive in many configurations.


• Compact, adaptable design: built to fit standard wheel builds and frames used in DIY e-bikes, scooters, and other light-mobility projects.


• Low-maintenance operation: enclosed bearings and gear paths minimize exposure to the elements and wear.


• Modular integration: designed to work with commonly used controllers, batteries, and throttles in DIY systems (requires matching voltage and connector compatibility).

Who is this for?

This wheel hub motor assembly is ideal for riders and builders looking to convert a conventional wheel into an electric-drive solution. It’s well-suited for urban commuters seeking a clean, quiet, and dependable propulsion option, hobbyists prototyping new e-mobility concepts, and workshops upgrading a bike, scooter, or light vehicle with a durable hub motor.

Practical considerations and best practices

• Compatibility: verify your frame’s axle width, wheel diameter, and brake compatibility with the D28E hub motor assembly before purchasing or installing.


• Powertrain pairing: pair with a compatible controller and battery that match the system’s voltage and current requirements, along with a suitable throttle interface.


• Installation tips: ensure correct axle seating, secure fixing bolts, and proper wiring routing to avoid pinch points or strain on connectors.


• Maintenance: periodic inspection of the axle bearings and hub seals helps maintain smooth operation; keep the exposed surfaces clean and dry.

Upgrade your ride with the D28E wheel hub motor assembly and unlock true in-wheel propulsion. Whether you’re converting a favorite bike for daily commuting or prototyping a new e-mobility concept, this integrated hub delivers a compact, efficient, and visually tidy solution.
