Product Description
Electronic 5-Speed Internal Gear Hub For Premium City E-Bike OEM Projects
Product Overview
The E05 / LG-P7100-5D Electronic 5-Speed Internal Gear Hub is designed for premium city e-bike OEM projects that need wider gear coverage, electronic shifting and a clean rear-hub drivetrain layout. It combines automatic intelligent shifting, Bluetooth manual shifting and a 249% total gear range inside a sealed internal gear hub structure.
For premium city riding, E05 supports easier starts, climbing support and efficient cruising. The five-speed ratio range gives OEM teams more room to tune the riding experience for urban routes, gentle gradients and repeated stop-and-go use. For riders who prefer direct control, Bluetooth manual shifting keeps a manual option available.
For OEM validation, E05 should be evaluated together with rear frame structure, 142 mm O.L.D., 6-bolt disc brake layout, spoke specification, voltage platform, CAN Interface requirement, cable routing and waterproof target. The page should not publish custom shift strategy, controller protocol or unconfirmed compatibility details.
Key Features
- Premium City E-Bike Focus: Designed for high-end urban e-bike and smart commuter platforms.
- 5-Speed Internal Gear Coverage: Provides a 249% total gear range for starts, climbs and cruising.
- Automatic Intelligent Shifting: Helps reduce frequent rider-side gear selection.
- Bluetooth Manual Shifting: Keeps direct gear control available for selected projects.

Technical Advantages / How It Works
E05 uses an internal planetary gear hub structure to provide five gear ratios inside the rear hub. In a planetary gear system, the sun gear, planet gears and ring gear can form different transmission ratios when different members are driven, held or used as output. This allows the hub to provide multiple gear ratios without moving the chain across exposed sprockets.
For E05, the shift action is completed through electronic control and motor-driven shifting. This allows the hub to perform automatic intelligent shifting and Bluetooth manual shifting while keeping the core gear mechanism inside the rear hub.
Applications
E05 is suitable for premium city e-bikes, smart commuter platforms, OEM validation projects and high-end urban mobility products where smooth shifting, wider gear coverage and clean rear-wheel integration are important.
OEM Matching Notes
Before sampling or production, OEM customers should confirm rear frame drawing, 142 mm O.L.D. confirmation, 6-bolt disc brake layout, spoke specification, voltage range, CAN Interface requirement, cable routing, waterproof requirement, target vehicle type and expected riding conditions. Installation, control interface and shifting mode setup should be confirmed during project matching.
FAQ
Q: What is E05? A: E05 / LG-P7100-5D is an electronic 5-speed internal gear hub for e-bikes.
