17.2 Mm Back Wheel Bike Lock Smart Higher Torque Resistance Anti Theft Skewer

The 17.2 x 17.2 mm Wheel Lock is designed for hub motor e-bikes, electric scooters and OEM motor platforms that require a larger axle-hole hidden lock structure and stronger thermal adaptability. Based on GS3646, this configuration page focuses on larger motor matching and high-temperature application rather than the 15 x 15 mm HS3718 / DS3710 direction.

For hub motor vehicles, hidden installation inside the rear motor can be more suitable than external locks when the rear hub is already occupied by the drive motor. GS3646 keeps the lock concealed inside the motor structure while providing a larger axle-hole configuration for specific motor platforms.

The key selection difference is thermal and structural matching. GS3646 should be considered when the target motor platform requires the larger axle-hole design and higher operating temperature positioning. OEM teams should confirm motor inner space, end-cover sensing layout, controller logic and thermal requirements before sampling.

• 17.2 x 17.2 mm Axle-Hole Focus: Designed for motor platforms requiring a larger hidden lock matching structure.
• High-Temperature Motor Application: Positioned for projects with higher thermal requirements than standard 15 x 15 mm models.
• High-Torque Hidden Security: Supports stronger motor-side anti-tamper positioning for OEM projects.
• Hidden Rear Hub Motor Installation: Places the lock inside the motor instead of using an exposed external lock structure.
• Vehicle-Side Smart Control: Supports UART, RS485 and CAN integration with controller, IoT or battery-side systems.
• Speed-Aware Safety Logic: Uses project-defined protection speed and motor-end-cover sensing layout with recommended evenly distributed magnets.
• Mechanical Anti-Lock Protection: Supports safer locking behavior when matched with the vehicle controller logic.
• OEM Thermal Matching Required: Motor internal space, axle hole, thermal requirement and sensing layout must be confirmed before sampling.

GS3646 is integrated inside the rear hub motor to provide concealed wheel security for motor platforms where external locks may be difficult to install or too exposed. The hidden structure helps reduce visible attack points and keeps the security module closer to the motor system.

The larger axle-hole design is the main configuration value. Compared with 15 x 15 mm models, GS3646 is intended for motor structures that require 17.2 x 17.2 mm matching. This makes motor drawing confirmation and internal space review especially important.

The high-temperature positioning should be used carefully and supported by project confirmation. The standard operating temperature is listed in the source parameters, while short-time extreme temperature notes should be treated as project-confirmed conditions before public quotation or upload claims.

GS3646 is suitable for hub motor e-bikes, electric scooters, shared mobility vehicles and OEM motor platforms that require hidden motor-side security with a larger axle-hole structure and high-temperature positioning.

It is especially useful for projects where 15 x 15 mm motor hub locks are not the correct structural match, and where motor thermal requirements need to be reviewed together with security strength and controller safety logic.

Before sampling or production, confirm motor internal structure, axle hole size, motor end-cover speed sensing layout, thermal requirement, torque requirement, controller protocol, voltage, waterproof requirement, brake interface and final compliance documents.

Q: What is the main application focus of GS3646?

A: GS3646 focuses on larger axle-hole hidden wheel lock matching and high-temperature motor platform applications.

Q: How is GS3646 different from HS3718 and DS3710?

A: GS3646 uses a 17.2 x 17.2 mm axle-hole direction and higher temperature positioning, while HS3718 and DS3710 use the 15 x 15 mm direction.

Q: Where is the lock installed?

A: It is installed inside the rear hub motor and requires motor matching. It is not an external frame lock or ordinary brake lock.

Q: Does the product include brake parts?

A: No. Brake interface and braking performance depend on the hub motor brake interface.

Q: What should be confirmed before sampling?

A: Confirm motor inner structure, axle hole, thermal requirement, speed sensing layout, torque requirement, voltage and controller safety logic.

Q: Can the short-time extreme temperature note be published directly?

A: It should be treated as project-confirmed information before public quotation or final upload claims.
