The Smart Front Hub Lock is designed for shared bike fleets, shared e-bikes and OEM mobility platforms that need front wheel security with integrated braking and smart lock control. Using ZS3702 as the reference model, this product direction focuses on front hub replacement for shared bicycle wheel security.
Shared bicycles operate in public environments where the front wheel security architecture must support anti-theft control, outdoor durability and service-friendly integration. ZS3702 combines drum brake function, electronic locking and speed sensing inside the front hub direction, helping vehicle brands reduce separate external lock components.
The lock can work with the main controller, IoT module or battery-side system for vehicle-side smart control. Its 4-magnet speed sensing supports wheel movement detection for lock strategy, while the front hub replacement direction helps OEM teams build a compact front wheel security module for shared bike projects.
- Smart Front Hub Lock: Designed for shared bike front wheel security and vehicle-side lock control.
- Front Wheel Hub Replacement: Provides a front hub security direction for compatible shared bicycle platforms.
- Integrated Drum Brake And Lock: Combines braking, electronic locking and speed sensing in one front hub module.
- Shared Fleet Application: Suitable for shared bicycles, shared e-bikes and rental mobility vehicles.
- 4-Magnet Speed Sensing: Supports vehicle-side wheel movement detection for smarter lock control.
- UART / RS485 / CAN Integration: Works with main controller, IoT or battery-side systems.
- IPX7 Complete-Unit Protection: Supports outdoor shared fleet operation and wet environments.
- OEM Wheel Matching Required: Front fork structure, O.L.D., spoke specification and axle matching should be confirmed before sampling.

ZS3702 integrates the front hub lock with drum brake function and electronic control. When the vehicle-side system sends a command, the front hub lock can execute lock or unlock operation as part of the shared bike security system.
The front wheel security value is the main application focus. Instead of adding an exposed lock around the frame, OEM teams can use a front hub replacement direction that keeps braking and locking functions integrated around the wheel hub.
For shared fleet projects, final matching should be confirmed by front fork structure, O.L.D., spoke specification, axle matching, brake layout and control protocol. Speed sensing and waterproof protection support outdoor fleet operation without changing the source-listed parameters.
ZS3702 is suitable for shared bicycles, shared e-bikes, rental bicycles and OEM mobility platforms that require front wheel security with integrated drum brake hub lock control.
It is especially useful for shared bike projects where front wheel locking, braking, speed sensing and vehicle-side smart control need to be combined into a compact hub module.
Before sampling or production, confirm front fork structure, O.L.D., spoke specification, axle matching, brake layout, voltage, communication protocol, speed sensing logic and waterproof requirement.
