The Smart Servo Brake Lock is designed for rental e-bike fleets and shared mobility platforms that need rear wheel braking and smart lock control in one compact rear hub assembly. It helps operators manage vehicle security through the controller, IoT module or battery-side system while reducing the need for exposed external lock components.
For rental vehicles, the rear wheel lock needs to support frequent outdoor use, remote operation and vehicle-side status management. This servo brake lock direction combines brake-side installation with electronic lock control, allowing the rear hub area to serve both braking and anti-theft functions.
SS2715 is suitable for standard fleet brake-lock integration with flexible axle-hole matching. ATL3733 is suitable for projects that require additional anti-lock safety-speed logic and expanded communication matching. OEM teams can select the final model according to rear hub structure, protocol, axle-hole requirement and safety strategy.
Rental Fleet Rear Hub Security: Designed for rental e-bikes and shared vehicles that need brake-side smart locking.
Integrated Brake And Lock Structure: Combines rear wheel braking and electronic lock control in one rear hub assembly.
SS2715 Standard Option: Suitable for standard smart servo brake lock integration with flexible axle-hole matching.
ATL3733 Anti-Lock Option: Suitable for projects requiring mechanical safety-speed logic and I2C-ready communication.
4-Magnet Speed Sensing: Supports wheel movement detection for vehicle-side lock control strategy.
Smart Vehicle Communication: Works with controller, IoT or battery-side systems through model-specific communication interfaces.
IPX7 Lock-Core Protection: Supports outdoor rental fleet operation, rain exposure and routine washing conditions.
OEM Matching Required: Rear hub structure, brake diameter, axle hole, speed logic and protocol should be confirmed before sampling.

The servo brake lock receives lock or unlock commands from the vehicle-side control system and performs the corresponding mechanical action inside the rear wheel brake-lock assembly. This supports remote fleet operation without relying only on a separate exposed lock.
Speed sensing is important for rental e-bike use. The vehicle system can use wheel movement information and project-defined protection logic before allowing lock execution, helping improve safety control during high-frequency public operation.
For fleet projects, the main value is integrated rear hub security. The product combines anti-theft locking, rear wheel braking, speed-aware control and outdoor durability in one brake-side solution. The final model should be selected according to communication interface, axle-hole design, safety logic and operating environment.
SS2715 and ATL3733 are suitable for rental e-bikes, shared electric bicycles, shared mobility vehicles and OEM rear wheel platforms that require smart servo brake locking with vehicle-side control.
This product direction is especially useful for public rental fleets where rear wheel security, integrated braking, speed-aware locking and weather-resistant lock-core protection need to be considered together.
Before sampling or production, confirm rear hub structure, rear motor structure, brake diameter, axle hole, wheel size, voltage, communication protocol, speed sensing strategy, operating temperature, waterproof requirement and vehicle load condition.
