Automatic 3-Speed Hub Motor Gearbox For Shared E-Bike Fleets

R900 is a 36V automatic 3-speed hub motor gearbox for shared e-bike fleets and managed mobility platforms. By integrating the hub motor and electronic shifting system into one rear-wheel unit, it helps reduce exposed drivetrain complexity and supports a more consistent riding experience across different users.

In public-use e-bike scenarios, riders may not understand gear selection or may only use the vehicle for short urban trips. R900 helps move the shifting task into the system. PedalFlow™ technology supports smoother gear changes while pedaling, helping the vehicle respond naturally during starts, acceleration, climbing and frequent stop-and-go riding.

For fleet operators, the standard 148 mm O.L.D., 36V DC platform, 250W / 350W rated power, 50 N.m maximum torque, ≤55 dB noise level, IPX6 waterproof rating and chain or belt drivetrain options provide a clear baseline for project evaluation. Disc Brake and V Brake versions can both be considered according to the final fleet vehicle structure.

• Shared E-Bike Fleet Focus: Designed for managed mobility and public-use electric bicycle projects.
• Integrated Motor + Shifting Unit: Reduces exposed drivetrain complexity around the rear wheel.
• PedalFlow™ Shifting Technology: Supports gear changes while pedaling in frequent urban use.
• Consistent Public-Use Riding: Helps reduce differences caused by rider gear-selection habits.
• 36V Standard Platform: Keeps fleet evaluation focused on the current published configuration.
• 148 mm O.L.D.: Provides a clear frame matching baseline.
• Chain / Belt Options: Supports different fleet drivetrain planning directions.
• Disc Brake / V Brake Versions: Both can be considered for production.
• IPX6 Waterproof Rating: Supports outdoor shared e-bike use.
• Application Page Boundary: This page references R900 and does not create a new fleet-only SKU.

R900 combines motor drive and electronic 3-speed shifting in one hub motor gearbox. For shared e-bike fleets, this integration helps simplify the drivetrain experience for different riders and reduces the need for user-operated gear selection.

PedalFlow™ technology supports shifting while pedaling, which is valuable in stop-and-go urban riding. The system is positioned to help maintain smoother drive behavior during starts, acceleration and moderate climbing without publishing unpublished controller customization details.

This R900-based application page is suitable for shared e-bike fleets, rental mobility platforms, public-use electric bicycles, campus e-bike projects and managed urban mobility vehicles where consistent riding experience and reduced exposed drivetrain complexity are important.

Fleet customers should confirm rear frame drawing, 148 mm O.L.D., brake direction, wheel specification, chain or belt drivetrain layout, controller interface, cable routing, charging/maintenance workflow, waterproof requirement and target operating environment before sampling.

Q: Is this a separate fleet-only model?
A: No. This page is an application-focused page based on the R900 standard product.

Q: Why is R900 useful for shared e-bike fleets?
A: It integrates motor drive and electronic 3-speed shifting, helping reduce rider-side gear selection and support more consistent public-use riding.

Q: Does the page publish CANbus customization?
A: No. CANbus customizable shift logic is not published on the product page.

Q: What voltage should fleet buyers use for evaluation?
A: The current published standard version is 36V DC.

Q: Can both Disc Brake and V Brake versions be produced?
A: Yes. Disc Brake and V Brake versions can both be considered for production.

Q: Does this product page include certification?
A: No. Certification is not written on the product page.

Q: What should fleet customers confirm before sampling?
A: Confirm rear frame structure, O.L.D., brake type, wheel specification, drivetrain layout, controller interface, cable routing and operating environment.
