48V Locking Drum Brake Hub Electronic Control Locking Brake Lock For Bike

ZS3702 is the front-wheel version of the Lofandi 80 mm drum brake hub lock series. ZS3702 is the front hub replacement version with 110 mm O.L.D. and 1.3 kg reference weight. It integrates the wheel hub, drum brake and smart electronic locking mechanism into one compact assembly for shared e-bikes, rental bicycles and fleet mobility platforms.

The product is developed for vehicle projects that need braking, anti-theft locking and electronic control in a single wheel module. It supports 5V DC / 48V DC vehicle electrical systems and can communicate with the main controller, IoT module or battery system through UART, RS485 or CAN.

The built-in Hall speed sensing structure uses a standard 4-magnet ring to support movement detection. Together with patented mechanical Anti-lock protection and customer-defined electronic protection speed, the lock helps reduce the risk of improper locking while the wheel is moving.

The complete unit reaches IPX7 waterproof protection and uses high-strength metal die-cast structural parts for outdoor fleet operation. OTA online upgrade support also makes the series suitable for connected shared mobility platforms that require remote management and future firmware maintenance.

• Front Wheel Security: Designed as a front hub replacement with integrated locking function.
• 80 mm Drum Brake Structure: Combines wheel hub, drum brake and lock mechanism in one assembly.
• Smart Locking Control: Supports vehicle-side electronic control through controller, IoT or battery system.
• Multi-Protocol Communication: Supports UART, RS485 and CAN integration.
• Speed Sensing Support: Uses standard 4-magnet ring speed sensing for movement status detection.
• High Torque Resistance: Torque resistance test value reaches ≥160N·m.
• IPX7 Waterproof Rating: Suitable for outdoor shared bike and e-bike operation.
• 300kgf Axle Load Strength: Supports reliable front wheel use in mobility vehicles.

The ZS3702 front drum brake hub lock integrates the mechanical hub structure, drum brake system and electronic locking function. The lock can receive commands from the main controller, IoT module or battery system and execute locking or unlocking based on vehicle-side control logic.

The built-in speed sensing solution supports standard 4 magnets per ring, evenly distributed. This helps the system identify wheel movement and supports safer locking logic. When matched with vehicle control software, the electronic protection speed can be defined according to customer requirements.

As a front wheel product, ZS3702 is especially suitable for shared bike projects where front wheel locking is preferred for installation layout, appearance design or anti-theft strategy. Its integrated drum brake hub structure reduces separate component assembly and helps improve overall vehicle integration.

• Smart front drum brake hub lock for shared bikes and e-bikes.
• Replaces the front hub and integrates with the wheel assembly.
• 80 mm drum brake diameter for compact braking structure.
• 110 mm O.L.D. for front wheel hub compatibility.
• 36H13G spoke specification.
• M12 * 1.25 axle specification.
• Compatible with 5V DC / 48V DC electrical systems.
• Supports UART, RS485 and CAN communication.
• IPX7 waterproof design for outdoor mobility use.
• Suitable for shared bicycle fleets, rental e-bikes and urban mobility projects.

ZS3702 is suitable for shared bikes, e-bikes, rental bicycles and urban fleet mobility vehicles that need front wheel security and integrated drum brake function. It is especially useful for operators who prefer front hub replacement as the main anti-theft solution.

For OEM and fleet projects, the product helps combine braking, locking and speed sensing in one compact front wheel module. This can simplify vehicle structure, reduce separate component installation and support remote vehicle management through controller or IoT integration.
