Integrated Hub Motor Gearbox Smart E Bikes Hub Motor Regenerative Braking

The Integrated Gearbox Hub Motor Solution is designed for smart e-bikes, urban e-bike platforms and OEM drive-system projects that need rear-wheel motor power and electronic shifting in a compact integrated module. Based on R900, this application page focuses on smart e-bike drive system positioning rather than treating the product as a standalone internal gear hub.

R900 combines a gear-drive rear hub motor with electronic 3-speed internal shifting. This integrated structure helps OEM teams reduce separated drivetrain assemblies around the rear wheel, while supporting smoother riding behavior for starts, climbing, acceleration and daily urban use. The product is especially relevant for smart e-bike platforms where motor output and shift logic need to be considered together.

For smart e-bike OEM projects, the system should be reviewed as part of the complete vehicle architecture. Rear frame clearance, wheel size, voltage platform, controller interface, CANbus matching direction, brake layout, drivetrain matching and cable routing should all be confirmed before sampling or vehicle-level testing.

• Integrated Drive-System Positioning: Combines rear hub motor packaging with electronic 3-speed gearbox functionality.
• R900 Reference Product: Uses the confirmed R900 hub motor gearbox source information as the product basis.
• Smart E-Bike Application: Designed for OEM platforms where motor output and shifting behavior need system-level matching.
• PedalFlow Shifting Logic: Source material references PedalFlow shifting logic for smoother pedaling-related gear changes.
• CANbus Matching Direction: Shift logic can be reviewed through CANbus matching according to vehicle project requirements.
• Compact Rear-Wheel Architecture: Reduces separated visible drivetrain assemblies around the rear wheel.
• Chain Or Belt Matching: Drivetrain matching should be confirmed according to the final frame and rear-wheel design.
• OEM Validation Required: Controller interface, cable outlet, brake matching and vehicle-level testing must be confirmed before production.

R900 uses electronic shifting rather than a purely mechanical automatic mechanism. The source material describes shift logic that can respond to riding conditions such as speed, torque, cadence and slope-related data. This allows OEM teams to review shifting behavior together with motor output and controller-side settings.

The integrated rear-wheel design combines the hub motor and electronic 3-speed gearbox into one compact system. For smart e-bike projects, this can support cleaner vehicle packaging, fewer separated drivetrain modules and a more differentiated drive-system story than a conventional rear hub layout.

Because R900 is part of the vehicle drive system, final suitability must be validated at the vehicle level. Controller matching, cable routing, brake type, wheel build, frame clearance, load conditions and riding scenario should be reviewed before sampling and mass production.

R900 is suitable for smart e-bikes, urban commuter e-bikes, cargo e-bikes, utility e-bikes and OEM mobility platforms that require integrated motor and electronic shifting functionality in the rear wheel system.

It is especially useful for projects where compact motor packaging, smart shifting logic, drivetrain differentiation and vehicle-level integration are more important than a conventional hub motor or standalone internal gear hub.

Before sampling or production, OEM customers should provide vehicle drawings, rear frame structure, O.L.D. requirement, wheel size, brake type, drivetrain layout, controller interface, voltage platform, cable routing, target load and expected operating conditions. Certification, total gear ratio and controller compatibility should be confirmed before public claims.

Q: What type of product is R900?

A: R900 is positioned as a hub motor gearbox system that integrates a rear hub motor with electronic 3-speed internal shifting.

Q: Is R900 a normal internal gear hub?

A: No. It should be evaluated as part of the vehicle drive system because it includes hub motor and gearbox integration.

Q: What is the main application focus of this page?

A: The page focuses on integrated drive-system positioning for smart e-bike OEM projects.

Q: Can the shifting logic be customized?

A: The source material mentions CANbus-based shift logic customization. Final scope should be confirmed by the engineering team according to controller compatibility and validation requirements.

Q: Does it support chain or belt drive?

A: The parameter table lists chain / belt drivetrain matching. Final sprocket or belt-line design should be confirmed with frame and drivetrain drawings.

Q: What should OEM customers confirm before sampling?

A: Confirm frame structure, O.L.D., wheel size, brake type, drivetrain layout, voltage platform, controller interface, cable routing, load condition and operating scenario.

Q: Are certifications confirmed?

A: The source table lists certification as '/', so certification documents should be treated as To Be Confirmed until final compliance files are provided.
