Smart Security Front Disc Lock UART RS485 Bicycle Disc Brake Lock

The Front Roller Brake Hub Lock is designed for shared e-bikes, city bicycles and fleet mobility vehicles that use roller brake front wheel systems. Unlike ZS3749 and ZS3726, which are designed for disc brake interfaces, ZS3728 is configured with a roller brake interface, making it suitable for vehicle platforms where roller brake compatibility is required.
The product replaces the front hub and integrates smart locking control into the wheel assembly. It supports 5V DC / 48V DC electrical systems, UART / RS485 / CAN communication and speed sensing through a standard 4-magnet ring. With 100 mm O.L.D. and IPX7 waterproof protection, ZS3728 is suitable for outdoor shared mobility operation and compact front wheel security design.

• Roller Brake Interface: Designed for front wheel systems using roller brake structures.
• 100 mm O.L.D.: Suitable for common front hub replacement applications.
• Smart Front Hub Lock: Integrates electronic locking function into the front wheel hub.
• Multi-Protocol Communication: Supports UART, RS485 and CAN.
• Speed Sensing Support: Standard 4-magnet ring for wheel movement detection.
• High Torque Resistance: ≥160N·m torque resistance test.
• IPX7 Waterproof Rating: Suitable for outdoor fleet use.
• Different From Disc Brake Models: Positioned for roller brake platforms instead of 6-bolt disc brake systems.

ZS3728 works as a smart front hub lock for roller brake vehicle platforms. The lock receives commands from the main controller, IoT module or battery system and performs locking or unlocking according to the vehicle’s control logic.
The built-in speed sensing solution uses a standard 4-magnet ring, helping the vehicle system detect wheel movement and define electronic protection speed according to project requirements. Its roller brake interface gives it a clear difference from the disc brake versions in the same ATL hub lock family.
For OEM projects, ZS3728 provides a practical front wheel locking solution when the vehicle platform does not use disc brakes. It keeps the front wheel structure compact while integrating smart security, speed sensing and outdoor waterproof protection.

ZS3728 is suitable for shared e-bikes, city bicycles and fleet mobility vehicles that use front roller brake systems. It is especially useful for projects where front wheel security is needed but the vehicle platform does not use a disc brake interface.
For operators, ZS3728 provides smart locking, speed sensing and IPX7 outdoor protection in one front hub module. For OEM brands, it offers a roller brake compatible alternative to front disc hub lock models.

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: Shared e-bikes, city bicycles and fleet vehicles using front roller brake systems.
Q: How is this model different from the other ZS front hub locks?
A: 100 mm O.L.D. with roller brake interface instead of 6-bolt disc brake interface.
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 Roller 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.
