Product Description
Automatic 2-Speed Chain Drive Disc Brake Hub For City E-Bikes| 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-bike and commuter bicycle projects that need mechanical automatic shifting, 6-bolt disc brake matching and a narrower rear frame structure than the 135 mm A02 versions.
With CentriGear mechanical shifting, the hub automatically changes between a 1.00 starting ratio and a 1.33 cruising ratio. Riders do not need a manual shifter for normal city riding, making the drivetrain simple and intuitive for daily commuting.
For OEM projects, LG-N7000-2D should be selected when the frame requires 130 mm O.L.D., chain-drive layout and 6-bolt disc brake compatibility. Its maintenance-free sealed internal gear structure helps create a cleaner rear-wheel layout with fewer exposed shifting components.

Technical Advantages / How It Works
LG-N7000-2D uses the A02 CentriGear mechanical shifting structure. Centrifugal-force triggering works with planetary gear operation to shift between two internal ratios. The lower ratio supports easier starting, while the higher ratio supports efficient cruising after the bicycle is moving.
The page should not publish trigger speed, threshold value or threshold adjustment procedure. Spoke hole number is also not published for LG-N7000-2D at this stage.
