The Rear Wheel Hub Lock is designed for shared bicycles, shared e-bikes and OEM fleet platforms that need rear wheel anti-theft protection with integrated braking and smart lock control. Using ZS3704 as the reference model, this product direction focuses on rear hub replacement for fleet bike security.
Rear wheel security can be useful when the vehicle frame, brake layout or anti-theft strategy is better matched to rear-side locking. ZS3704 combines drum brake function, electronic locking and speed sensing inside the rear hub direction, helping shared bike operators protect the wheel while keeping the lock integrated with the vehicle structure.
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 rear hub replacement direction gives OEM teams a dedicated rear wheel anti-theft option for shared fleet projects.
- Rear Wheel Hub Lock: Designed for bike anti-theft protection in shared and fleet vehicle platforms.
- Rear Hub Replacement Direction: Provides a rear wheel security option for compatible shared bicycle structures.
- Integrated Drum Brake And Lock: Combines braking, electronic locking and speed sensing in one rear hub module.
- Fleet Anti-Theft Application: Suitable for shared bikes, 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 fleet operation and wet environments.
- OEM Rear Wheel Matching Required: Rear frame structure, O.L.D., spoke specification and axle matching should be confirmed before sampling.

ZS3704 integrates rear hub locking with drum brake function and electronic control. When the vehicle-side system sends a command, the rear hub lock can execute lock or unlock operation as part of the bike security system.
The rear wheel anti-theft value is the main application focus. Instead of treating the lock as a separate exposed component, OEM teams can use a rear hub replacement direction that combines braking, locking and wheel movement detection around the rear wheel module.
For shared fleet projects, final matching should be confirmed by rear frame 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.
ZS3704 is suitable for shared bicycles, shared e-bikes, rental bicycles and OEM mobility platforms that require rear wheel anti-theft protection with integrated drum brake hub lock control.
It is especially useful for fleet projects where rear wheel locking, braking, speed sensing and vehicle-side smart control need to be combined into one hub module.
Before sampling or production, confirm rear frame structure, O.L.D., spoke specification, axle matching, brake layout, voltage, communication protocol, speed sensing logic and waterproof requirement.
