The 4-Magnet Anti-Lock Drum Brake Lock is designed for fleet e-bike and shared mobility platforms that need anti-lock rear brake security with a more precise speed sensing direction. Based on ABSS3725, this page focuses on the 4-magnet sensing configuration within the ABSS anti-lock expansion brake lock series.
ABSS3725 uses a 95 mm expansion brake lock structure and supports vehicle-side communication through common smart mobility protocols. Its key distinction is the 4 Magnets / Ring speed sensing solution, which should be kept separate from the 3-magnet ABSS3716 and ABSS3708 references.
This product direction is suitable for buyers who care about speed-sensing brake lock logic in fleet projects. The lock-core waterproof rating, brake structure, axle-hole options and speed protection logic should be confirmed against the final vehicle design before sampling.
ABSS3725 combines expansion brake locking with electronic smart lock control and speed sensing. The 4-magnet sensing configuration helps provide wheel movement information to the vehicle-side controller before lock behavior is executed.
The anti-lock mechanical structure is intended to reduce unsafe locking risk when matched with appropriate vehicle logic. Final electronic protection speed, wheel diameter relationship, rear hub structure and communication protocol should be confirmed during OEM development.
This page is suitable for fleet e-bikes, shared e-bikes, rental mobility vehicles and OEM rear-wheel platforms that require 4-magnet speed sensing with anti-lock rear expansion brake lock integration.

Q: What is the reference model?
A: The reference model is ABSS3725.
Q: How is ABSS3725 different from ABSS3716?
A: Both use a 95 mm brake diameter and >=160 N.m torque resistance direction, but ABSS3725 uses 4 Magnets / Ring while ABSS3716 uses 3 Magnets / Ring.
Q: How is ABSS3725 different from ABSS3708?
A: ABSS3725 is a 95 mm 4-magnet direction, while ABSS3708 is a 110 mm heavy-duty direction with >=300 N.m torque resistance.
Q: What waterproof wording should be used?
A: Use IPX7 Lock Core, because that is the source parameter wording.
Q: What should OEM customers confirm?
A: Confirm rear hub structure, axle hole, wheel diameter, speed logic, communication protocol and brake matching.
