Product Description
Automatic 3-Speed Hub Motor Gearbox For Shared E-Bike Fleets
Product Overview
E03-7003D is an electronic 3-speed internal gear hub for shared e-bike fleets and public-use city mobility projects. In shared riding scenarios, users may not want to think about gear selection during short trips. E03 helps move shifting decisions into the system while keeping a manual Bluetooth option available for project configuration.
The sealed rear-hub structure and 6-bolt disc brake layout support cleaner fleet vehicle design. For fleet projects, E03 should be evaluated together with frame drawings, charging and maintenance workflow, voltage platform, cable routing, CAN Interface requirement and waterproof target.

Technical Advantages / How It Works
E03 supports automatic intelligent shifting through electronic control and internal gear operation. This helps reduce frequent rider-side gear decisions during starts, cruising and urban stop-and-go use. Bluetooth manual shifting can be retained when the fleet project requires direct control or service configuration.
Applications
Suitable for shared e-bike fleets, rental e-bike platforms, public-use city mobility vehicles and OEM fleet projects that need electronic 3-speed internal shifting.
OEM Matching Notes
Fleet customers should confirm frame structure, wheel build, brake layout, voltage platform, cable routing, CAN Interface requirement, maintenance workflow and target operating conditions.
FAQ
