Product Description
An anti-lock servo drum brake lock for shared e-bike platforms, integrating rear wheel braking, smart lock control, 4-magnet speed sensing, I2C-ready communication and 30 RPM mechanical safety-speed protection.
Product Description
Anti-Lock Servant Brake Lock With 30RPM Protection For Shared E-Bikes
Product Overview

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.

Technology / How It Works

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.

Applications

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.
