Anti Lock Bike Drum Brake Servo Drum Brake Lock 30 RPM For Shared E Bikes

The Anti-Lock Servo Drum Brake Lock is designed for shared e-bikes, shared bicycles and fleet mobility vehicles that need rear wheel braking, electronic lock control and safer anti-lock protection in one compact rear hub assembly.
ATL3733 integrates a rear drum brake structure with a smart locking module. The lock can receive commands from the vehicle controller, IoT module or battery-side system, allowing the vehicle platform to manage lock and unlock actions remotely. Its hidden rear hub installation helps reduce exposed locking parts and supports cleaner vehicle design for public-use mobility projects.
Compared with standard brake-lock configurations, ATL3733 adds stronger safety-oriented control through 4-magnet speed sensing and mechanical safety-speed protection. This makes it suitable for shared e-bike projects where wheel movement detection, remote operation and anti-lock logic are important for daily fleet use.

Anti-Lock Servo Brake Lock: Combines rear drum braking and electronic smart lock control for shared mobility vehicles.
30 RPM Mechanical Safety Protection: Adds mechanical safety-speed logic, with actual vehicle speed related to wheel diameter.
4-Magnet Speed Sensing: Supports wheel movement detection for safer lock control.
I2C-Ready Communication: Supports UART, RS485, CAN and I2C for vehicle-side integration.
Rear Hub Integration: Designed for left-side rear hub or rear motor installation.
Remote Lock Control: Works with controller, IoT or battery-side systems.
IPX7 Lock-Core Protection: Suitable for outdoor operation, rain and routine washing conditions.
Fleet Mobility Use: Built for shared bikes, e-bikes, rental vehicles and public-use platforms.

ATL3733 works by combining a mechanical drum brake structure with an electronically controlled locking module. When the vehicle-side system sends a command, the lock performs the corresponding lock or unlock action while remaining integrated with the rear wheel brake assembly.
The 4-magnet speed sensing structure helps the vehicle system detect wheel movement status before locking. Together with the 30 RPM mechanical safety-speed protection, ATL3733 provides an additional safety layer for shared e-bike and fleet vehicle applications.
For OEM projects, ATL3733 is especially useful when the vehicle requires compact rear hub integration, remote smart lock control, speed-aware locking logic and reduced external lock exposure.

ATL3733 is suitable for shared e-bikes, shared bicycles, rental mobility vehicles and fleet platforms that require rear wheel braking, electronic locking, speed sensing and anti-lock safety logic.
It is especially suitable for public-use vehicles where operators need remote lock control, rear wheel anti-theft protection, vehicle status feedback and compact rear hub integration.

Before sampling, OEM customers should provide rear hub structure, frame drawings, wheel size, brake layout, axle hole requirement, voltage platform, communication protocol, controller or IoT interface, speed sensing requirement, waterproof requirement, vehicle weight, load condition and target operating environment. Lofandi can support technical matching, drawing confirmation, sample preparation and project validation.
