The ABSS3725 4-Magnet 95 mm Anti-Lock Rear Drum Brake Lock is developed for shared e-bike fleets and OEM mobility platforms that specify a four-magnet wheel-speed sensing layout. It combines 95 mm expansion-brake performance, vehicle-controlled rear-wheel locking and model-specific Hall sensing in a rear hub left-side or rear motor left-side installation direction.
Four evenly distributed magnets per ring provide the ABSS3725 sensing arrangement for project-defined wheel-movement input. This model-specific layout gives OEM teams a clear option when matching the sensing architecture with the rear-wheel and controller design. Electronic protection speed is configured around the vehicle project, while a separate 30 RPM mechanical safety locking condition helps suppress unintended engagement outside the intended locking range.
ABSS3725 provides >=160 N.m lock-structure torque resistance, 5V-60V DC, UART/RS485/CAN/I2C interface options, OTA online upgrade and an IPX7 lock core. RoHS / REACH and public real-vehicle assembly, braking, torque, IPX7, salt-spray and final-inspection media are confirmed. Expansion-brake braking performance follows the ISO 4210-2015 boundary.

Technology / How It Works
The 95 mm expansion-brake mechanism produces rear-wheel braking by applying the brake shoes against the internal braking surface through the vehicle's matched mechanical actuation. Its expansion-brake performance is evaluated in accordance with ISO 4210-2015.
For locking, the vehicle controller communicates through the selected project interface. Four-magnet Hall sensing provides wheel-movement input for the configured electronic protection speed. The independent 30 RPM mechanical safety locking condition adds a physical locking-safety boundary. Together they support movement-aware lock control while the expansion brake retains its matched mechanical actuation. OTA support is available for the electronic lock within the approved project architecture.
ABSS3725 is suited to shared e-bike fleets, rental mobility systems and OEM vehicle programs that require a 95 mm rear brake-lock assembly with four evenly distributed sensing magnets. It should be selected when the sensing layout, controller input and rear-wheel packaging are confirmed together as project requirements.
Before sampling, provide the rear hub or rear motor drawing, 95 mm brake requirement, axle-hole direction, wheel diameter, vehicle parameters, operating profile, voltage, selected interface, controller/IoT architecture, four-magnet layout requirement and lock workflow. Confirm installation clearance, magnet placement, connector, cable routing, accessory BOM, brake actuation and complete-vehicle validation in approved project documents.
Q: What is the defining difference of ABSS3725? A: It is the 95 mm ABSS model with four evenly distributed magnets per ring and >=160 N.m lock-structure resistance.
Q: Does four-magnet sensing mean higher accuracy? A: The confirmed fact is the four-magnet layout. Accuracy, response or resolution comparisons require project test data and are not claimed on this page.
Q: How is ABSS3725 different from ABSS3716? A: Both use a 95 mm brake diameter and >=160 N.m resistance. ABSS3725 uses four magnets per ring, while ABSS3716 uses three.
Q: How is ABSS3725 different from ABSS3708? A: ABSS3725 is the 95 mm, 4-magnet, >=160 N.m direction. ABSS3708 is the 110 mm, 3-magnet, >=300 N.m heavy-duty direction.
Q: Can ABSS3725 work with different vehicle interfaces? A: UART, RS485, CAN or I2C can be selected according to the fleet controller and project electrical architecture.
Q: Does Anti-Lock regulate braking pressure? A: No. It describes lock-engagement protection using electronic speed logic and a 30 RPM mechanical safety condition.
Q: Are OTA, IPX7 and certification available? A: OTA online upgrade is supported, IPX7 applies to the lock core, and RoHS / REACH are confirmed.
Q: What must be confirmed for the four-magnet project? A: Confirm magnet placement, controller input, electronic protection speed, wheel diameter, rear-wheel structure, interface and the final vehicle validation plan.
