Product Description
Brake-Lock 3-Speed Internal Gear Hub For Shared Bicycles
Product Overview
LG-N3010-3V is the M03 fork-out manual 3-speed internal gear hub for city and commuter rear-wheel projects using a V Brake and 120 mm O.L.D. Its V Brake direction, 44.7 mm and 39.7 mm chainlines, 0.58 mm offset and 33.3 / 36 mm axle-from-hub geometry establish the model's integration identity.
The internal 0.73, 1.00 and 1.36 ratios provide low, direct and high-ratio directions within a 186% range. This gives riders a straightforward manual choice for starting, climbing, steady city riding and higher-speed travel.
V Brake & Frame Integration
V Brake compatibility is a frame and rear-wheel selection condition, not a generic statement that covers every rim-brake system. The hub must be reviewed with the complete brake mounts, rim, wheel build, chainline, dropout and control layout.
The external shift-control position supports a visible cable connection and a defined inspection point. Exact shifter model and adjustment reference remain part of project matching.

Technical Advantages / How It Works
The planetary transmission produces three ratios inside the hub. A project-confirmed manual shifter changes cable position, and the outside-fork control transfers that input to the internal mechanism. The chain remains on its selected drive-side line while the hub changes the transmission ratio.
Applications And OEM Value
LG-N3010-3V is positioned for city bicycles, commuter bicycles and OEM rear-wheel projects designed around a V Brake and 120 mm frame spacing. Urban e-bike evaluation requires confirmation of the complete frame, brake, drivetrain input, wheel and control system; the page does not promise universal e-bike fit.
Before sampling, confirm the V Brake layout, 120 mm O.L.D., chainline, axle geometry, rim and wheel specification, shifter, cable route and intended use.
Manufacturing & Quality Review
LG-N3010-3V has confirmed IPX6 and RoHS / REACH fields. V Brake performance, rim/brake validation, endurance cycles and model-specific inspection criteria remain project-document fields. Factory media may support capability review without becoming an unverified SKU-level test claim.
FAQ
Q: What is the difference between LG-N3010-3V and LG-N3010-3R? A: LG-N3010-3V is the V Brake version with 44.7 / 39.7 mm chainlines. LG-N3010-3R is the Roller Brake version with 45 / 40 mm chainlines and confirmed named shifters.
Q: Is this a 120 mm hub? A: Its confirmed O.L.D. is 120 mm. Frame, axle and dropout geometry must still be reviewed together.
Q: Which shifter matches this model? A: The exact M03 manual 3-speed shifter is confirmed during project matching.
Q: Are V Brake components included? A: Included components follow the quotation and are not implied by this page.
Q: What information is needed before sampling? A: Frame drawing, V Brake layout, 120 mm O.L.D., chainline, rim/wheel build, shifter, cable route and application.
