The Smart Hub Lock is designed for e-bikes, shared e-bike fleets and OEM front wheel platforms that need front hub security with wheel movement detection. It integrates smart locking into the front hub replacement structure while supporting 4-magnet speed sensing for vehicle-side lock control.
For connected e-bike projects, front wheel locking should work with the vehicle control system instead of acting as a separate exposed accessory. The 4-magnet sensing layout helps provide wheel movement information to the controller before lock commands are executed.
ZS3749 supports standard front fork spacing, while ZS3726 supports a wider front hub direction for custom or special e-bike platforms. Both reference models keep the 6-bolt disc brake interface, smart front hub lock architecture and IPX7 complete-unit protection.
- 4-Magnet Speed Sensing: Supports wheel movement detection for smarter front hub lock control.
- Smart Front Hub Lock: Integrates electronic locking into the front hub replacement structure.
- ZS3749 Standard O.L.D. Direction: Suitable for standard front fork e-bike platforms.
- ZS3726 Wide O.L.D. Direction: Suitable for wider front fork or custom e-bike platforms.
- 6-Bolt Disc Interface: Supports front wheel disc brake hub lock matching.
- Vehicle-Side Control: Works with controller, IoT or battery-side systems using source-listed communication interfaces.
- IPX7 Complete-Unit Protection: Supports outdoor e-bike and shared fleet operation.
- OEM Matching Required: Front fork O.L.D., axle diameter, spoke specification, disc interface and sensing logic should be confirmed.

The front hub lock receives lock or unlock commands from the vehicle-side system and performs the corresponding locking action inside the front hub replacement assembly. This keeps the lock integrated with the wheel structure.
The 4-magnet sensing layout provides wheel movement information for vehicle-side decision-making. This supports safer and smarter lock execution logic for shared e-bikes, rental bicycles and connected OEM platforms.
For OEM teams, ZS3749 and ZS3726 provide two front fork spacing directions while keeping the same speed-sensing keyword value. Final matching should be confirmed by front fork O.L.D., disc interface, axle diameter, spoke specification and controller protocol.
This smart hub lock direction is suitable for e-bikes, shared e-bike fleets, rental bicycles and OEM front wheel platforms that require 4-magnet speed sensing and smart front hub lock control.
It is especially useful for connected vehicle projects where front wheel security, wheel movement detection, disc brake interface matching and outdoor fleet operation need to be considered together.
Before sampling or production, confirm front fork O.L.D., 6-bolt disc interface, axle diameter, spoke specification, brake parts matching, voltage, communication protocol, speed sensing logic and waterproof requirement.
