The Speed-Sensing Anti-Lock Brake Lock is designed for smart e-bikes, shared e-bike fleets and OEM rear wheel platforms that need wheel movement detection and safer rear brake lock control. Using ABSS3725 and ABSS3716 as reference models, this product direction focuses on Hall speed sensing and mechanical Anti-Lock safety for connected rear brake lock systems.
For smart e-bikes, a rear brake lock should work with the vehicle control platform rather than act as an isolated mechanical part. Hall speed sensing helps provide wheel movement information to the controller, while Anti-Lock protection supports safer lock execution when the vehicle-side logic is correctly defined.
ABSS3725 is suitable for projects that want to highlight precision sensing layout, while ABSS3716 supports lightweight rear brake lock integration. Both reference models are built around the 95 mm anti-lock expansion brake lock direction and can be matched with controller, IoT or battery-side systems.
- Hall Speed Sensing Focus: Supports wheel movement detection for smart e-bike rear brake lock control.
- Anti-Lock Safety Support: Mechanical Anti-Lock protection helps support safer lock execution logic.
- ABSS3725 Precision Sensing Direction: Suitable for projects emphasizing 4-magnet sensing layout positioning.
- ABSS3716 Lightweight Direction: Suitable for projects emphasizing lightweight 3-magnet rear brake lock integration.
- Smart Vehicle-Side Control: Works with controller, IoT or battery-side systems using source-listed communication interfaces.
- 95 mm Rear Brake Lock Direction: Provides compact rear wheel integration for smart and shared e-bike platforms.
- IPX7 Lock-Core Protection: Supports outdoor smart e-bike operating environments.
- OEM Matching Required: Rear wheel structure, sensing layout, controller logic and brake layout should be confirmed before sampling.

The lock works with vehicle-side electronic control to perform rear brake lock and unlock actions. The Hall speed sensing layout helps the control system understand wheel movement status before the lock command is executed.
The Anti-Lock structure is the key safety advantage. When paired with controller-side logic, it helps reduce unsafe locking risk and makes the brake lock more suitable for smart e-bike platforms that require safety-aware control.
For OEM teams, the main selection question is sensing layout and integration priority. ABSS3725 should be used when 4-magnet precision sensing positioning is preferred, while ABSS3716 can support lightweight rear brake lock matching.
This speed-sensing Anti-Lock brake lock direction is suitable for smart e-bikes, shared e-bike fleets, rental mobility vehicles and OEM rear wheel platforms that require Hall speed sensing and safety-aware rear brake lock control.
It is especially useful for connected vehicle projects where rear brake lock behavior must be coordinated with controller logic, wheel movement information, outdoor operation and fleet security requirements.
Before sampling or production, confirm rear wheel structure, brake layout, mounting side, axle hole, speed sensing layout, electronic protection speed strategy, voltage, communication protocol and controller safety logic.
