SS2715 Smart Servo Drum Brake Lock For Shared E-Bike Fleets

SS2715 is a smart servo drum brake lock developed for shared e-bikes, rental bicycles and fleet mobility vehicles that need rear-wheel braking and electronic locking within one integrated assembly. Installed on the left side of the rear hub or rear motor, it combines a 100 mm servo brake direction with vehicle-controlled smart locking, reducing the need for a separate external wheel-lock structure.

For public-use vehicles, the key value is coordinated rear-wheel control. A dual Hall sensing module works with four evenly distributed magnets per ring to provide wheel-speed information for the vehicle-side control strategy. The electronic protection speed is defined during project matching, allowing the controller or IoT system to evaluate wheel movement before executing the selected lock-control logic.

SS2715 operates across a confirmed 5V-60V DC range and is available with CAN, RS485 or UART smart-lock interface options. The selected interface is matched to the vehicle project, while OTA online upgrade support provides a basis for later electronic-lock firmware maintenance. With 10 mm and 12 mm axle-hole options, IPX7 lock-core protection, RoHS / REACH certification and a servo brake direction compliant with ISO 4210-2015, SS2715 gives OEM teams a defined starting point for rear-wheel brake-lock integration.

• Integrated Rear-Wheel Brake And Smart Lock: Combines a 100 mm servo drum brake direction with electronic wheel locking in one assembly.
• Shared Fleet Application Focus: Developed for shared bikes, shared e-bikes, rental fleets and public-use mobility vehicles.
• Dual-Hall Speed Sensing: Uses a dual Hall module to support vehicle-side wheel-movement detection.
• Four-Magnet Ring: Standard four-magnet configuration is evenly distributed for the confirmed sensing arrangement.
• Project-Defined Electronic Protection Speed: Allows the vehicle project to define the electronic lock-protection threshold and control strategy.
• CAN / RS485 / UART Interface Options: Gives OEM teams selectable smart-lock communication directions for vehicle integration.

SS2715 combines mechanical rear-wheel braking with an electronically controlled locking module. The servo brake performs the rear-wheel braking function, while the smart-lock section receives lock or unlock control through the selected CAN, RS485 or UART interface. The interface version, voltage platform and electronic protection settings are confirmed as part of the complete vehicle project.

The dual Hall module and four-magnet ring provide wheel-speed information to the control system. This information supports the project-defined electronic protection logic before a lock command is executed. The electronic protection setting, controller response and complete-vehicle behavior are therefore evaluated together during project matching and validation.

SS2715 is suitable for shared bicycles, shared e-bikes, rental e-bike fleets and OEM mobility platforms requiring rear-wheel braking, electronic lock control and wheel-speed sensing in one rear-hub-area solution. It is especially relevant to public-use vehicles where vehicle-side fleet control, repeated outdoor operation and structured system integration need to be evaluated together.

Before sampling, confirm the rear hub or rear motor structure, 100 mm brake direction, 10 mm or 12 mm axle-hole requirement, wheel size, frame and rear-wheel clearance, 5V-60V DC electrical platform, selected CAN/RS485/UART interface, controller or IoT connection, speed-sensing strategy, electronic protection setting, operating environment and validation plan. Complete-unit dimensions, current, actuation time and lifetime values should follow approved SS2715 project data rather than general industry assumptions.

Q: What is SS2715?

A: SS2715 is a smart servo drum brake lock for shared e-bikes and fleet mobility vehicles. It combines rear-wheel servo braking, electronic locking and wheel-speed sensing in one rear-hub-area assembly.

Q: Where is SS2715 installed?

A: It is matched to the left side of the rear hub or rear motor. The complete frame, hub or motor structure, axle hole, brake layout and wheel clearance should be confirmed before sampling.

Q: Which smart-lock interfaces are available?

A: CAN, RS485 and UART are available as project-selected smart-lock interface options. The required interface version is confirmed according to the vehicle controller or IoT architecture.

Q: How does the speed-sensing system support lock control?

A: A dual Hall module and four evenly distributed magnets per ring provide wheel-speed information. The vehicle project uses this information with a defined electronic protection speed and control strategy before executing lock control.

Q: Does SS2715 support OTA upgrade?

A: Yes. The electronic lock supports OTA online upgrade. The upgrade platform, workflow and project interface are confirmed during technical matching.

Q: Does SS2715 have a 30 RPM mechanical anti-lock layer?

A: No. SS2715 uses project-defined electronic speed-protection logic and does not include ATL3733's separate 30 RPM mechanical safety-speed layer.

Q: What protection and compliance information is confirmed?

A: SS2715 has IPX7 lock-core protection and RoHS / REACH certification. The 100 mm servo brake direction complies with ISO 4210-2015. The source also confirms environmental storage, high-temperature/high-humidity and 72-hour neutral salt-spray fields in the shared parameter table.
