DSS1735 is an electronic bicycle disc brake lock for urban e-bikes and OEM city-mobility projects. It integrates around matched 6-bolt bicycle disc brake kits at the left rear dropout and rear disc-brake area, adding concealed rear-wheel immobilization without presenting the product as the brake caliper, rotor or a complete brake kit. This fixed layout keeps the security component close to the wheel structure and supports a cleaner complete-bike design.

The product combines vehicle-controlled locking with wheel-movement input. A single Hall sensing module works with three evenly distributed magnets per ring to provide speed information for the project-defined electronic protection strategy. This allows the lock command, vehicle controller and intended operating conditions to be evaluated as one complete system during OEM development.

DSS1735 provides a confirmed torque-resistance test value of at least 160 N.m and supports 5V DC or 48V DC vehicle platforms. UART, RS485 and CAN are available as project-selected smart-lock interface directions, while the electronic lock supports OTA online upgrade. Matching with 6-bolt bicycle disc brake kits, IPX7 complete-unit protection and defined environmental validation fields give OEM teams a practical basis for city e-bike development and testing.

• Concealed Rear-Wheel Integration: Positions the electronic lock at the left rear dropout and disc-brake area for a clean OEM installation.
• Vehicle-Controlled Locking: Receives lock and unlock control through the selected vehicle-side electrical architecture.
• Single-Hall Speed Sensing: Supplies wheel-movement information for the electronic protection strategy used by the complete vehicle project.
• Three-Magnet Ring Arrangement: Uses three evenly distributed magnets per ring for the confirmed sensing configuration.
• Project-Defined Protection Speed: Allows the electronic lock-protection setting to be matched to the vehicle and operating scenario.
• UART / RS485 / CAN Options: Gives OEM teams selectable interface directions without forcing one communication architecture.
• 5V DC / 48V DC Options: Supports two confirmed electrical-platform directions for project integration.
• 6-Bolt Disc-Brake Matching: Provides a defined starting point for rear dropout, locking structure and disc-brake area development.
• IPX7 Complete-Unit Protection: Supports outdoor urban mobility integration within the confirmed waterproof scope.
• OTA Online Upgrade: Provides an electronic-lock firmware maintenance direction after vehicle-side integration.

The dedicated locking structure is assembled in the rear disc-brake area according to the approved installation sequence. During operation, the vehicle system sends the lock or unlock command through the selected interface, and the electronic actuator controls the locking mechanism to immobilize rear-wheel rotation. The component performs wheel locking; it is not the brake caliper and does not replace the bicycle braking system.

Wheel-movement information comes from the single Hall module and three-magnet arrangement. The complete vehicle project uses this input together with its project-defined electronic protection setting before executing the selected control logic. Voltage, interface, controller connection and protection behavior are therefore confirmed together during sampling and complete-bike validation.

DSS1735 is suitable for urban e-bikes, commuter e-bikes, consumer city e-bikes and OEM mobility projects that need a compact, fixed rear-wheel locking component. It is particularly relevant where the bike brand wants security hardware integrated into the complete vehicle architecture while retaining a clean exterior and selectable communication direction.

Before sampling, confirm the rear dropout drawing, wheel and rear disc-brake layout, 6-bolt interface direction, locking-structure clearance, installation sequence, 5V or 48V electrical platform, selected UART/RS485/CAN interface, main controller/IoT/battery connection, Hall and magnet arrangement, electronic protection setting, operating environment and complete-bike validation plan. Hub, axle and brake components are not included in the DSS specification. Use the approved installation video for assembly guidance and confirm final mechanical dimensions with the project drawing.

Q: What is DSS1735? A: DSS1735 is a vehicle-controlled electronic rear-wheel lock for urban e-bikes and OEM city-mobility projects. It is installed at the left rear dropout and rear disc-brake area and provides a confirmed torque-resistance test value of at least 160 N.m.

Q: Is DSS1735 a bicycle brake caliper? A: No. DSS1735 is a wheel-immobilization component positioned in the rear disc-brake area. The bicycle still requires its specified braking system and matched brake components.

Q: How does DSS1735 differ from DSS1736? A: DSS1735 is the standard torque-resistance model with a test value of at least 160 N.m and is focused on urban and regular OEM projects. DSS1736 uses a test value of at least 300 N.m and is positioned for shared-bike, rental and higher-demand fleet applications.

Q: Which communication interfaces are available? A: UART, RS485 and CAN are available as project-selected interface options. The required interface and vehicle-side connection are confirmed before sampling.

Q: How is wheel movement detected? A: The confirmed sensing arrangement uses a single Hall module and three evenly distributed magnets per ring. The resulting wheel-movement information supports the project-defined electronic protection strategy.

Q: Is the electronic protection speed fixed? A: No public fixed threshold is specified. The electronic protection speed and complete-vehicle control behavior are defined and validated according to project requirements.

Q: Is DSS1735 waterproof? A: The complete unit has a confirmed IPX7 rating. Final installation, connectors, harness routing and complete-vehicle sealing should still be validated as part of the OEM project, and IPX7 should not be interpreted as approval for high-pressure washing.

Q: Does DSS1735 replace a frame lock or anchored lock? A: DSS1735 adds integrated rear-wheel immobilization. The complete vehicle security plan may still use frame anchoring, tracking or other measures according to the parking risk and operating model.
