LG-N3000-3R is an M03 inside-fork manual 3-speed internal gear hub for rear-wheel projects using a Roller Brake. Built for city commuting and shared-bicycle directions, it brings the transmission system inside the rear hub while retaining rider-directed manual gear selection through the matched LL-3S02E Twist Shifter.
This inside-fork model should not be confused with LG-N3010-3R, the M03 fork-out Roller Brake version. LG-N3000-3R uses 141 mm O.L.D., a 200 mm axle, 1.1 kg average weight and LL-3S02E matching; LG-N3010-3R uses different axle geometry, chainline, weight and confirmed shifter directions. The two models share the M03 manual three-speed principle, but they are not interchangeable product pages.
The hub provides a 186% total gear range through three internal ratios: 0.73, 1.00 and 1.36. Gear 1 is the low-ratio direction for starting and climbing, Gear 2 is the direct ratio for normal riding, and Gear 3 is the high-ratio direction for higher-speed riding. This gives the rider a practical manual range without relying on an exposed derailleur system.
- M03 Inside-Fork Manual 3-Speed System: A source-backed manual internal gear hub direction for rear-wheel integration.
- Roller Brake Configuration: Built for projects using a roller-brake rear hub layout.
- 186% Three-Speed Range: Ratios of 0.73, 1.00 and 1.36 cover start, direct-ratio and higher-speed riding directions.
- LL-3S02E Twist Shifter Matching: Preserves a defined manual control relationship.
- 141 mm O.L.D.: Gives frame teams a clear rear-dropout selection input.
- Defined Chainline Data: G1 47 mm and G2 42.5 mm support drivetrain layout review.
- Confirmed Wheel-Build Fields: #13 / #14 spokes, 3 mm holes and 36H.
- Sealed Internal Gear Direction: Original product source describes protection from mud and rain exposure.
- IPX6 And RoHS / REACH: Confirmed model-level protection and compliance fields.
- City And Shared Bicycle Direction: Supports M03's source-backed daily-city and shared-bicycle positioning without a fleet-lifetime promise.

LG-N3000-3R uses an internal planetary gear principle to provide three ratios within the rear hub. In a planetary gear system, different relationships between the sun gear, planet gears and ring gear create different transmission ratios without moving the chain across an external multi-sprocket cassette.
The manual control path begins with the matched LL-3S02E Twist Shifter. Its cable action changes the selected position at the hub-side control mechanism, allowing the internal transmission to engage the intended ratio. The shifter, cable and hub should be treated as one matched system; a generic three-speed shifter or third-party hub must not be assumed compatible.
The original M03 product source describes a sealed structure intended to isolate mud and rain exposure. The confirmed IPX6 rating and RoHS / REACH certification may be published for this model. Specific maintenance intervals, test cycles and service-life figures remain outside this public page unless separately approved.
LG-N3000-3R is matched with a Roller Brake and the LL-3S02E internal 3-speed Twist Shifter. These are the confirmed associated components for the public page.
For wheel construction, the authority data specifies #13 / #14 spokes, 3 mm spoke-hole diameter and 36H. The silver hub is customizable, and its average weight is 1.1 kg. The rear-wheel project must still confirm the exact brake configuration, sprocket/cog arrangement, cable route and complete frame layout; the page does not define unlisted supplied parts.

The internal three-speed range is designed around 0.73, 1.00 and 1.36 ratios. The 0.73 first gear supports starts and climbing direction, the 1.00 second gear provides the direct ratio, and the 1.36 third gear supports higher-speed riding direction. Together they create the confirmed 186% range for common city riding transitions.
The rider controls the selected ratio through the LL-3S02E Twist Shifter. Rotate the grip downward to tension the shift cable and shift up from Gear 1 toward Gear 3. Rotate it upward to release cable tension and shift down from Gear 3 toward Gear 1. During a gear change, briefly reduce pedal pressure, allow the selected position to engage and then resume normal pedaling.
This is a manual mechanical system. It must not be presented as automatic shifting, electronic shifting, full-load shifting or a hub-motor drivetrain.
LG-N3000-3R is suitable for city commuter bicycles and OEM rear-wheel projects using a Roller Brake and a 141 mm inside-fork layout. The original M03 positioning also identifies shared bicycles as an application direction.
Whether the project is a daily commuter bicycle or a shared-bicycle platform, the key selection condition remains the same: the complete vehicle must use the Roller Brake interface, 141 mm O.L.D., defined chainline, matched LL-3S02E control and appropriate wheel-build arrangement. Specialized fleet validation remains a separate project matter.
ELEVANDI project communication can cover model selection, Roller Brake integration, rear-frame data review, wheel-build matching, LL-3S02E control matching and the available inside-fork installation guidance. Samples, MOQ, delivery, warranty, spare parts and customization details follow the quotation and order process.
