100 mm Front Hub Lock For Standard Shared E-Bike Forks For OEM Projects
The 100 mm Front Hub Lock is designed for shared e-bike and city mobility platforms that need smart front-wheel security around a standard front fork layout. Based on ZS3749, this page focuses on 100 mm front hub replacement rather than a general front hub lock family page.
For shared e-bike projects, front-wheel lock matching must be clear before sampling because front fork O.L.D., axle diameter, spoke specification and brake interface all affect wheel build. ZS3749 provides a standard front hub direction with 6-bolt disc brake interface and vehicle-side smart control.
This P2 page helps OEM buyers find the correct standard-front-fork direction without confusing it with wide front hub platforms or roller brake interface products. Final installation should be confirmed against the actual front wheel and controller layout.
- 100 mm Front Fork Focus: Designed around standard front hub replacement requirements for shared e-bike forks.
- ZS3749 Reference Model: Uses ZS3749 as the parameter and image basis.
- 6-Bolt Disc Brake Interface: Supports front disc-brake-oriented hub lock matching while brake parts are not included.
- 4-Magnet Speed Sensing: Standard 4 magnets per ring support front wheel movement detection.
- Smart Vehicle Integration: Supports controller, IoT or battery-side power source according to source data.
- IPX7 Complete Unit: Suitable for outdoor shared mobility and city e-bike operation.

ZS3749 works as a smart front hub replacement. The lock receives vehicle-side commands and performs lock or unlock operation through the integrated hub lock structure, while speed sensing provides wheel movement information to the vehicle system.
The core configuration value is front fork matching. OEM teams should confirm the 100 mm front fork direction, axle diameter, spoke specification, disc brake layout, controller protocol and speed protection logic before sampling.
This product page is suitable for shared e-bikes, city e-bikes, rental mobility vehicles and OEM front-wheel platforms that require standard 100 mm front hub lock matching.
