Product Description
Automatic 2-Speed Internal Gear Hub | Official Product Description
Product Overview
LG-N7000-2D is the compact 130 mm O.L.D. chain-drive version in the A02 automatic 2-speed internal gear hub series. It is designed for city e-bikes and commuter bicycle projects that need a simple self-shifting hub with 6-bolt disc brake compatibility, while keeping the rear frame structure narrower than the 135 mm versions.
The hub shifts automatically between two ratios, 1.00 and 1.33, helping riders start smoothly and cruise more efficiently in urban riding. Its sealed internal structure protects the gear mechanism from dust, mud and rainwater, reducing routine adjustment work compared with exposed external shifting systems.
Key Features
- Automatic 2-speed shifting reduces rider operation during daily city riding.
- 133% total gear range supports easier starting and efficient cruising.
- Sealed internal gear structure helps protect transmission parts from dust, mud and rainwater.
- Chain Drive System configuration for the target drivetrain layout.
- 6-Bolt Disc Brake matching for the selected rear brake structure.
- 130 mm O.L.D. rear hub structure for frame matching.
- IPX6 waterproof rating and RoHS / REACH certification support international product planning.
Technical Advantages / How It Works
The A02 automatic internal gear hub uses a mechanical self-shifting structure to change between two gear ratios according to riding conditions. The first ratio provides stable starting support, while the second ratio improves pedaling efficiency at higher city riding speeds. This automatic shifting experience reduces rider operation and makes the bicycle easier to use, especially for commuters who prefer a simple and intuitive ride.
Because the gear mechanism is built inside the hub shell, the system is less exposed to external contamination than traditional external shifting systems. This enclosed structure helps reduce chain alignment issues, dirt accumulation and frequent adjustment work. For e-bike brands, the A02 series offers a practical solution for clean urban vehicle design, with different models available for chain drive, belt drive, disc brake and drum brake lock requirements.

Applications
The Automatic 2-Speed Internal Gear Hub is suitable for urban e-bikes, city commuter bicycles, light electric mobility vehicles and daily-use bicycle platforms. It is especially useful for riders who want a simple riding experience without manual shifting.
For city commuting, the 2-speed automatic structure helps make starting and cruising easier. For OEM bicycle brands, the sealed hub design reduces exposed drivetrain components and supports cleaner vehicle styling. With chain-drive, belt-drive, disc brake and drum brake lock options, the A02 series can be matched to different frame structures and urban mobility projects.
FAQ
Q: What is this model best suited for?
A: Urban e-bikes and city bicycle projects that need a compact 130 mm rear dropout disc brake hub.
Q: How is this model different from the other A02 versions?
A: 130 mm O.L.D., 6-bolt disc brake, chain-drive layout with G1 49.4 mm and G2 44.5 mm chainline.
Q: Does it require manual shifting?
A: No. The A02 series uses a mechanical automatic 2-speed shifting structure and does not require a manual shift lever for normal riding.
Q: What should be confirmed before sampling?
A: Confirm rear frame O.L.D., brake interface, chainline or belt line, spoke specification, axle matching, wheel build and target riding scenario.
Q: Can Lofandi support OEM project matching?
A: Yes. OEM support can include product selection, drawing review, drivetrain matching, sample preparation and project validation according to the vehicle requirements.
Q: What ordering information should buyers provide?
A: Please provide expected order volume, sample quantity, target market, vehicle type, configuration requirements and validation schedule. Price, MOQ and lead time should be confirmed after project details are clear.
Q: What quality or compliance information is available?
