Smart 5-Speed Internal Gear Hub is an electronic internal gear hub designed for premium urban e-bikes, shared e-bike fleets and OEM smart bicycle projects that need smoother shifting, cleaner rear-wheel integration and a wider gear range for daily riding conditions.
Built around an electronic 5-speed rear hub structure, E05 combines automatic intelligent shifting, Bluetooth manual shifting and a 249% total gear range in one compact drivetrain solution. It helps the bicycle cover start-up, climbing, cruising and repeated stop-and-go riding with fewer rider-side gear decisions, making the riding experience more intuitive for city users and easier to manage for platform operators.
For OEM teams, E05 provides a source-backed smart drivetrain direction with 142 mm O.L.D., 6-bolt disc brake matching, 36H spoke specification, 15V-60V DC operating voltage range, CAN Interface and IPX6 protection. These confirmed parameters give vehicle development teams a clearer basis for frame, brake, wheel, electrical and waterproof matching before sampling.

### Construction & Integration
E05 is built as a sealed rear internal gear hub, placing the gear mechanism inside the hub body rather than relying on exposed external shifting movement. This structure supports a cleaner rear-wheel appearance and helps premium e-bike brands create a more integrated drivetrain layout.
The enclosed internal gear structure helps reduce direct exposure to rain, dust and road contamination, supporting more stable daily use in urban mobility conditions. With 142 mm O.L.D., 198 mm axle length, M12 x 1.25 thread size and 36H spoke specification, E05 should be evaluated together with the rear frame drawing, wheel build plan and brake layout during OEM project matching.
### Performance & Engineering
Equipped with five internal gear ratios and a 249% total gear range, E05 is designed to support common e-bike riding phases, including easier starts, climbing support, cruising efficiency and repeated speed changes in city traffic.
The automatic intelligent shifting function helps reduce the need for constant rider-side gear selection. When the bicycle starts, climbs or returns to steady cruising, the system can support more natural gear changes as part of the riding process. For users or projects that still require direct control, Bluetooth manual shifting keeps a manual option available.
The shift action is completed through electronic control and motor-driven shifting. This is the recommended public technology wording for E05. Detailed control logic and vehicle-side matching should remain part of project-level technical communication.
### Components & Technology
Featuring 6-bolt disc brake matching, CAN Interface and 250K bps baud rate, E05 gives OEM teams a clear starting point for vehicle-side integration review. The 15V-60V DC operating voltage range also supports project-level electrical matching across different e-bike development platforms.
The internal gear mechanism follows the general planetary gear principle. Different gear ratios are achieved inside the rear hub, allowing the bicycle to shift without moving the chain across exposed external sprockets. Combined with electronic control and motor-driven shifting, E05 supports automatic and Bluetooth manual shifting while keeping the main gear structure protected inside the hub.
Detailed control setup, CAN matching, cable routing and shifting mode configuration should be confirmed during project communication rather than published as general website content.
E05 is suitable for premium city e-bikes, smart urban commuter e-bikes, shared e-bike fleet platforms, rental e-bike projects and cargo or utility e-bike applications that need electronic internal shifting and cleaner rear-wheel integration.
Whether the project targets a high-end city commuter model or a managed shared fleet platform, E05 provides an electronic 5-speed internal gear hub direction that keeps shifting more intuitive for the rider and more integrated for the vehicle brand.
Installation method, control interface, shifting mode setup and complete vehicle matching should be confirmed during project communication.
Q: Does E05 support automatic and manual shifting?
A: Yes. E05 supports automatic intelligent shifting and Bluetooth manual shifting. The final control setup should be confirmed during project matching.
Q: What riding conditions does the 249% gear range support?
A: The 249% total gear range helps cover common e-bike riding phases such as start-up, climbing, cruising and repeated stop-and-go riding.
Q: What is the public technology description for E05?
A: The public technology wording should be electronic control and motor-driven shifting. Detailed control logic and vehicle-side matching should be confirmed during project communication.
Q: Can CANbus control details be published on the product page?
A: The product page can state CAN Interface and 250K bps baud rate. Detailed protocol logic, shift strategy and controller matching should be confirmed during project communication.
Q: What is the difference between E05 and R900?
A: E05 is an electronic 5-speed internal gear hub without an integrated motor. R900 belongs to a hub motor gearbox cooperation direction and should not be promoted as a public product page under the current publishing rule.
Q: What should OEM teams confirm before sampling?
A: OEM teams should confirm frame drawing, 142 mm O.L.D., brake layout, spoke specification, voltage range, CAN Interface requirement, cable routing, waterproof requirement and target riding conditions.
