The Wide Front Disc Hub Lock is designed for e-bike fleets, shared mobility vehicles and special front wheel platforms that require a wider hub structure together with smart lock control. Compared with the 100 mm front hub version, ZS3726 uses a 135 mm O.L.D. configuration, making it suitable for vehicle projects where the front fork, wheel structure or application requirements need a wider front hub assembly.
This product integrates the smart locking mechanism into the front hub area and supports 6-bolt disc brake interface compatibility. It can connect with the main controller, IoT module or battery system through UART, RS485 or CAN communication, allowing vehicle-side electronic locking and unlocking control.
- 135 mm Wide O.L.D.: Designed for wider front hub and special wheel structure applications.
- Front Hub Lock Integration: Combines hub replacement and smart lock control.
- 6-Bolt Disc Brake Interface: Suitable for disc brake e-bike platforms.
- Smart Vehicle Control: Supports connection with controller, IoT or battery system.
- Speed Sensing Support: Standard 4-magnet ring configuration for movement status detection.
- High Torque Resistance: ≥160N·m torque resistance test.
- IPX7 Waterproof Protection: Built for outdoor fleet operation.
- 300kgf Axle Load Strength: Supports reliable use in mobility vehicles.
ZS3726 works as a smart front hub lock with wider hub spacing. After receiving a lock or unlock command from the vehicle-side control system, the internal locking mechanism performs the required action. The system can also support speed sensing through a standard 4-magnet ring, helping the vehicle control system identify wheel movement.
The main difference of this model is its 135 mm O.L.D. structure. This gives it a different application position from standard 100 mm front hub locks. It is better suited for e-bike projects, wide front fork designs or customized fleet platforms that require more front hub spacing while still using a disc brake interface.
- Smart front disc hub lock with wider O.L.D. structure.
- 135 mm O.L.D. for special front wheel integration.
- 6-bolt disc brake interface.
- 36H13G / 36H12G spoke specification.
- Supports 5V DC / 48V DC electrical systems.
- UART, RS485 and CAN communication support.
- IPX7 waterproof rating.
- Suitable for fleet e-bikes, wider front hub systems and custom mobility projects.

ZS3726 is suitable for e-bike fleets, shared mobility vehicles and customized front wheel platforms that require a 135 mm front hub lock structure. It is especially useful for wider front fork designs, special wheel systems and vehicle projects where a standard 100 mm front hub lock is not suitable.
Before sampling, OEM customers should provide front fork drawing, target O.L.D., brake type, spoke specification, axle diameter, wheel size, voltage platform, communication protocol, speed sensing requirement, waterproof requirement and expected usage scenario. Lofandi can support model selection, drawing confirmation, sample preparation and project validation.
Q: What is this product mainly used for?
A: Custom e-bikes, wider front fork designs and special fleet platforms requiring 135 mm front hub spacing.
Q: How is this model different from the other ZS front hub locks?
A: 135 mm O.L.D. with 6-bolt disc brake interface for wider front hub structures.
Q: Does this product replace the front hub?
A: Yes. The source material lists the mounting position as front hub replacement. It integrates the hub structure and smart lock function into the front wheel assembly.
Q: What brake interface should be confirmed?
A: This model uses 6-Bolt Disc Brake Interface. The brake structure, front fork clearance and wheel build should be confirmed before sampling.
Q: Does it support speed sensing and anti-lock protection?
A: Yes. The source material lists 4 magnets per ring for speed sensing and a 30RPM mechanical safety locking reference. Final safety logic should be validated by vehicle project.
Q: What should OEM buyers provide before sampling?
A: Provide front fork drawings, O.L.D., brake type, axle diameter, spoke requirements, voltage, communication protocol, controller interface and target operating conditions.
Q: Are compliance documents confirmed?
A: The backend may list RoHS / REACH, but final documents and logos should be confirmed with the quality or sales team according to project requirements.
Q: Can it be used for shared fleets?
A: Yes, it is designed for shared e-bikes, rental vehicles and fleet mobility projects when the front hub, brake interface and control system match the selected model.
