The E05 / LG-P7100-5D Smart 5-Speed Internal Gear Hub is designed for urban commuter e-bikes and premium city platforms that need a smoother, cleaner and more intuitive shifting experience. As a core product in the iGearbox electronic internal gear hub series, E05 combines automatic intelligent shifting, Bluetooth manual shifting and a 249% wide gear range inside a rear-hub drivetrain structure.

For daily city riding, the main value is that shifting becomes less visible to the rider. E05 supports automatic gear changes for starts, climbs, cruising and repeated stop-and-go riding. When the bicycle stops, the system can return to a start gear for easier take-off. When the road climbs, automatic downshift helps maintain more stable torque support. For riders who still want direct control, Bluetooth manual shifting provides a manual option.

The sealed internal gear hub layout also supports a cleaner rear-wheel appearance than exposed shifting systems. With 142 mm O.L.D., 6-bolt disc brake matching, 15V-60V DC operating voltage range, CAN Interface and IPX6 waterproof rating, E05 gives urban e-bike brands a source-backed drivetrain direction for smart commuter models.

• Smart Urban Riding Focus: Designed for city e-bikes and commuter platforms where smooth riding experience matters.
• Automatic Intelligent Shifting: Helps the rider focus on the road instead of frequent gear selection.
• Automatic Return To Start Gear: Supports easier starts in stop-and-go city riding.
• Automatic Downshift On Climbs: Helps maintain more stable torque support when the road rises.
• 249% Wide Gear Range: Covers starts, climbing, cruising and daily urban speed changes.
• Bluetooth Manual Shifting: Keeps a manual control option for riders who want direct gear selection.
• Electronic Control And Motor-Driven Shifting: Supports precise internal gear change actuation.
• Sealed Internal Gear Structure: Helps reduce exposure to rain, dust and road contamination.
• Clean Rear-Wheel Appearance: Supports premium e-bike design with fewer exposed shifting components.
• Clear Product Boundary: E05 is an electronic internal gear hub, not a motor product.

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 general internal gear principle 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.

E05 is suitable for urban commuter e-bikes, premium city e-bikes, smart electric bicycles and daily mobility platforms where the brand wants easier starts, smoother climbing support, cleaner rear-wheel design and a more intuitive drivetrain experience.

Before sampling or production, OEM customers should confirm rear frame drawing, 142 mm O.L.D., 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.

Q: Is E05 a motor product? A: No. E05 is an electronic 5-speed internal gear hub installed in the rear hub position.

Q: What is the difference between E05 and E03? A: E05 is a 5-speed electronic internal gear hub with 249% total gear range. E03 is a 3-speed electronic internal gear hub.

Q: Does E05 support automatic and manual shifting? A: Yes. E05 supports automatic intelligent shifting and Bluetooth manual shifting. The exact configuration and control setup should be confirmed during project matching.

Q: Why is E05 suitable for urban commuter e-bikes? A: It provides wider gear coverage, automatic start and climb support, Bluetooth manual control and sealed rear-hub integration for daily city riding.

Q: Can the page publish CAN details? A: The page can publish CAN Interface and 250K bps baud rate. Detailed shift logic, controller strategy and protocol matching should be confirmed during project communication.

Q: What should OEM teams provide before sampling? A: Please provide rear frame drawing, 142 mm O.L.D. confirmation, 6-bolt disc brake layout, spoke specification, voltage range, controller interface requirement, target vehicle type and riding conditions.
