5 Speed Internal Gear Hub With Smart Electronic Shifting For E-Bikes

The E05 LG-P7100-5D is an electronic 5-speed internal gear hub designed for e-bike drivetrain projects that need a cleaner rear-wheel structure, wider riding coverage and more integrated shifting control. Its key difference is the combination of a 249% total gear range, electronic shifting parameters and a 6-bolt disc brake interface, making it better suited for city e-bikes, commuter platforms and OEM drivetrain development than a basic manual internal gear hub.

• Electronic 5-speed internal shifting for premium e-bike drivetrain design.
• 249% total gear range for city riding, cruising and light climbing.
• 6-bolt disc brake compatibility for rear-wheel e-bike platforms.
• Sealed internal structure helps reduce exposure to dust and rain.
• IPX6 waterproof rating for daily outdoor riding environments.
• 15V-60V DC operating voltage range for vehicle-side integration.

The E05 uses an internal 5-speed gear structure to change transmission ratios inside the hub rather than moving the chain across exposed sprockets. Electronic control supports more accurate gear positioning and helps reduce the adjustment drift often associated with mechanical cable systems. The 250K bps baud rate and 15V-60V DC operating range should be matched with the vehicle control system during OEM development.

This model is suitable for urban commuter e-bikes, premium electric bicycles, shared mobility bikes and OEM e-bike drivetrain development. It is especially useful for brands seeking a cleaner rear-wheel structure, lower exposed drivetrain maintenance and a more integrated riding experience.

Before sampling, OEM customers should confirm frame drawing, O.L.D., brake type, spoke specification, voltage range, controller interface, waterproof requirements and target riding conditions. Final compatibility should be reviewed with the technical team before mass production.

Q: Is LG-P7100-5D a hub motor?
A: No. Based on the provided parameters, LG-P7100-5D is an electronic 5-speed internal gear hub. It should not be described as an electric bike hub motor unless a motor version is separately confirmed.

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

Q: Can Lofandi support OEM or ODM drivetrain matching?
A: Yes. Project support can include product selection, drawing review, installation matching, electrical interface confirmation, sample preparation and validation support. Exact customization scope should be confirmed by project requirements.

Q: How is product quality verified before delivery?
A: Quality validation may include functional inspection, waterproof review, temperature-related testing, electrical parameter checking, installation matching and project-specific validation. Required test reports can be confirmed according to the order or OEM project.

Q: What is the ordering process for an OEM project?
A: Typical steps include requirement review, technical matching, quotation, sample confirmation, validation, final specification confirmation and batch order preparation. MOQ, lead time and price should be confirmed according to configuration and project volume.

Q: Can this product replace an external derailleur?
A: It can support a cleaner internal drivetrain layout in many city e-bike projects, but replacement feasibility depends on frame design, target gear range, brake layout, electrical integration and riding scenario.
