LG-N7003-2G is the drum brake lock version of the A02 automatic 2-speed internal gear hub. Its main value is the combination of mechanical self-shifting and drum brake lock matching, making it a practical option for low-maintenance city bicycles, public-use e-bikes and urban mobility platforms that require a protected rear hub brake layout.
Compared with the disc brake versions, this model uses a 135 mm O.L.D. structure, 56 mm G1 chainline, 50.8 mm G2 chainline and 30.8 mm brake mounting width. These differences should be checked carefully during frame and brake system matching.
The A02 series uses a mechanical automatic shifting structure based on CentriGear shifting logic. As riding speed changes, the internal mechanism shifts between the 1.00 and 1.33 ratios without a handlebar shifter. This gives daily riders a simpler experience, while helping OEM brands create a cleaner rear drivetrain layout with fewer exposed shifting components.
This model is best used for city e-bikes and low-maintenance bicycle platforms requiring integrated drum brake lock matching. It is especially relevant for OEM projects where the buyer wants a lower-maintenance alternative to exposed external shifting, but still needs the hub to match a specific brake interface, dropout width and drivetrain line.
