30RPM Bike Rear Drum Brake RoHS Bicycle Disc Brake Lock
The Anti-Lock Brake Lock is designed for shared e-bikes, rental e-bike fleets and public mobility vehicles that need safer rear wheel lock control through the vehicle-side system. It combines rear expansion brake locking, electronic control, speed sensing and mechanical Anti-Lock protection in one rear wheel assembly.
Fleet vehicles operate in unpredictable public environments, so rear wheel locking must be coordinated with wheel movement information and controller-side strategy. The Anti-Lock structure helps reduce unsafe lock activation risk when the product is correctly matched with the vehicle platform.
ABSS3716 supports a lightweight rear brake lock direction for compact fleet e-bike integration, while ABSS3708 supports a heavy-duty direction for public-use vehicles that require stronger anti-tamper security. OEM teams can select the suitable model according to brake diameter, rear wheel structure, torque requirement and control logic.
- Safety-Oriented Fleet Control: Supports safer rear wheel lock execution for shared and rental vehicle platforms.
- Mechanical Anti-Lock Protection: Helps reduce unsafe locking risk when matched with proper vehicle-side control logic.
- 3-Magnet Speed Sensing: Supports wheel movement awareness before electronic lock commands are executed.
- ABSS3716 Lightweight Direction: Suitable for compact fleet e-bike rear brake lock integration.
- ABSS3708 Heavy-Duty Direction: Suitable for public mobility vehicles requiring stronger rear wheel anti-tamper security.
- Smart Vehicle-Side Control: Works with controller, IoT or battery-side systems through source-listed communication interfaces.
- Rear Hub Or Rear Motor Side Mounting: Designed for rear wheel integration on compatible fleet vehicle platforms.
- IPX7 Lock-Core Protection: Supports outdoor operation, rain exposure and high-frequency fleet use.

The lock receives control commands from the vehicle controller, IoT module or battery-side system and performs the corresponding rear brake lock or unlock action. This allows fleet operators to manage rear wheel security through vehicle-side electronics instead of relying only on an external manual lock.
Speed sensing and Anti-Lock protection are the main safety values. Wheel movement information can support the vehicle control strategy before lock execution, while the mechanical Anti-Lock structure adds protection against unsafe locking scenarios in fleet operation.
For OEM projects, ABSS3716 and ABSS3708 provide two matching directions. ABSS3716 is useful for compact shared e-bike platforms, while ABSS3708 is better suited to heavy-duty public vehicles where higher anti-tamper strength is part of the project requirement.
This Anti-Lock brake lock direction is suitable for shared e-bikes, rental e-bike fleets, public mobility vehicles and OEM rear wheel platforms that require safety-oriented rear brake lock control.
It is especially useful for connected fleet projects where lock execution needs to consider wheel movement, controller logic, outdoor operation and rear wheel anti-theft protection together.
Before sampling or production, confirm rear wheel structure, brake diameter, mounting side, axle hole, vehicle load, speed sensing logic, electronic protection speed strategy, voltage, communication protocol and controller safety logic.
Q: What is the main application focus of this product page?
A: It focuses on Anti-Lock rear brake lock control for safer shared and rental fleet vehicle operation.
Q: Which reference models are used?
A: The page references ABSS3716 and ABSS3708 in the Anti-Lock Expansion Brake Lock series.
Q: How are ABSS3716 and ABSS3708 different?
