Product Description
ABSS3716 Compact Rear Drum Brake Lock For Rental E-Bikes
Product Overview
The ABSS3716 Bicycle Rear Drum Brake Lock is developed for urban rental e-bikes and shared mobility platforms that need braking and vehicle-managed parking control integrated at the rear wheel. Rather than asking riders or field teams to carry a separate locking device for routine platform control, the component works within the approved vehicle architecture and responds to the fleet's defined lock and unlock workflow.
Mechanical braking, electronic wheel immobilization and movement sensing are combined in one model-specific rear-wheel direction. The braking mechanism remains mechanically actuated, while the lock receives commands from the approved controller or IoT system. Wheel-movement input supports the electronic protection strategy, and a separate mechanical condition provides an additional engagement boundary.
For fleet engineering teams, the product is evaluated as part of the complete rear-wheel and service system. Installation access, wiring, brake actuation, controller behavior and final inspection can be reviewed together before vehicle rollout. Public installation and validation media provide a practical evidence set for this process without turning the component into a universal retrofit claim.
Key Features
- Rental-Operation Focus: Supports managed parking and return workflows for urban fleet E-bikes.
- Integrated Rear-Wheel Function: Combines mechanical braking and controller-managed immobilization in one project direction.
- Movement-Aware Lock Control: Supplies wheel-state input for the approved electronic protection strategy.
- Independent Mechanical Safety Layer: Adds a physical condition separate from software control.
- Rear Hub Or Rear Motor Installation: Supports two confirmed left-side structural directions.
- Vehicle-System Communication: Matches the lock with the selected controller or IoT architecture.
- OTA Support: Allows project-managed updates to the electronic lock within the approved system.
- Fleet Validation Evidence: Provides installation, braking, resistance, environmental and final-inspection media for review.

Technical Advantages / How It Works
When the rider applies the brake, the expansion mechanism drives the brake shoes against the internal braking surface. This mechanical action slows the wheel independently of the electronic lock. For parking control, the vehicle system sends the approved command through the selected interface. Hall sensing provides movement information for the configured protection logic, while the mechanical layer helps prevent lock engagement outside the intended state.
Applications
ABSS3716 is suited to shared e-bikes, urban rental bicycles and OEM fleet platforms that require integrated rear-wheel braking and managed locking. It supports projects where operating teams need a defined installation process, controller workflow and repeatable final inspection rather than a consumer replacement part.
OEM Matching Notes
Before sampling, provide the rear hub or rear motor drawing, wheel diameter, axle-hole requirement, controller or IoT architecture, selected interface, operating profile and lock workflow. Confirm brake actuation, installation clearance, connector, cable routing, service access, final BOM and complete-vehicle validation.
FAQ
Q: What defines ABSS3716 within the ABSS series?
A: It is the 95 mm, 3-magnet model with confirmed >=160 N.m lock-structure resistance. These values support model selection; they do not describe braking torque, vehicle load or a complete security grade.
Q: Is ABSS3716 a replacement set of drum brake parts?
A: No. It is an integrated bicycle/e-bike rear drum brake lock component for an approved vehicle platform. The matching hub, axle, actuation parts and final BOM are confirmed separately.
Q: Can it be installed beside a rear motor?
A: Yes. Rear motor left-side and rear hub left-side directions are supported, subject to the approved drawing, axle-hole requirement, installation clearance and cable routing.
Q: How does it reduce unintended lock engagement while moving?
A: Hall movement input supports project-defined electronic protection, while a separate mechanical safety condition provides an additional physical boundary. This protection does not regulate braking pressure.
Q: Which communication interface should a fleet use?
A: UART, RS485, CAN or I2C is selected according to the vehicle controller and IoT architecture. The final connector, command workflow and electronic protection setting are confirmed in the project.
Q: Which public media can support fleet review?
A: Model-matched installation, vehicle assembly, braking, lock-resistance, lock-core waterproof, neutral salt-spray and final-inspection media can support engineering and quality review.
Q: What should be confirmed before sampling?
A: Confirm the rear-wheel drawing, wheel diameter, brake actuation, controller architecture, interface, lock workflow, cable routing, service access and validation plan.
