Smart Security Front Disc Lock 5V Shared EBikes Fleets Bike Disc Lock With Alarm

ZS3749 is the 100 mm front disc hub lock for shared e-bike and fleet mobility platforms that use standard front fork spacing. It replaces the front hub and integrates smart locking into the wheel assembly, reducing exposed lock components while supporting a 6-bolt disc brake interface.

This model is the standard 100 mm disc brake option in the ATL front hub lock group. It is suitable when the vehicle uses a common front hub structure but still requires electronic lock control, speed sensing, anti-lock protection and outdoor durability.

• Front hub replacement design integrates hub structure and smart locking.
• 100 mm O.L.D. for the target front fork and wheel platform.
• 6-Bolt Disc Brake Interface for the selected brake system.
• Built-in Hall speed sensing and 4 magnets per ring for movement detection.
• Anti-lock mechanical protection with 30RPM safety locking reference.
• 5V DC / 48V DC power and UART / RS485 / CAN communication support.
• IPX7 complete-unit waterproof protection for outdoor fleet operation.
• Electronic lock supports OTA online upgrade according to source material.

The ATL front hub lock combines a front hub structure with an internal smart locking mechanism. It can receive lock and unlock commands from the main controller, IoT module or battery-side system. The 4-magnet speed sensing structure helps the vehicle system detect wheel movement, while the mechanical anti-lock protection helps reduce safety risks caused by accidental locking.

The electronic protection speed can be defined according to project requirements. The mechanical safety locking speed is listed as 30RPM in the source parameters, and actual vehicle speed depends on wheel diameter. OEM teams should validate the lock logic at vehicle level before mass production.

ZS3749 is suitable for shared e-bikes, rental bicycles and fleet vehicles using standard 100 mm front fork structures and disc brake systems. Final application should be confirmed according to front fork spacing, brake interface, axle specification, wheel build, controller interface and fleet operating conditions.

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, rental bicycles and fleet vehicles using standard 100 mm front fork structures and disc brake systems.

Q: How is this model different from the other ZS front hub locks?

A: 100 mm O.L.D. with 6-bolt disc brake interface for standard front hub replacement.

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 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.
