Describe
This derailleur sensor is mounted on the derailleur cable and generates a signal during gear shifting. Upon receiving this signal, the bicycle's control system can then take appropriate action.
This sensor is widely used in mid-drive motor systems; it is compact, easy to install, and highly sensitive.

Shift Sensor SS-01 – Reliable Gear Position Detection for Modern Vehicles and Machinery
When I first started working with vehicle control systems, I noticed something simple but important: many performance issues don’t come from engines or controllers, but from small sensing errors. A shift sensor is one of those small components that quietly decides whether a system feels smooth or unstable.
The Shift Sensor SS-01 is designed to solve that problem. It provides accurate and stable gear position detection for motorcycles, electric vehicles, ATVs, UTVs, agricultural machinery, construction equipment, and industrial automation systems.
At Suzhou Minshine Electronics Co., Ltd., we have been focusing on controllers, displays, and sensors since 2003. Over the years, we have learned that reliability is not something written in specifications—it is something proven in real working environments.
The Shift Sensor SS-01 is a gear position detection device that converts mechanical gear movement into electrical signals. These signals are sent to the ECU or control system so the machine can understand exactly which gear is engaged.
Instead of guessing or estimating gear position, the system receives direct and real-time feedback from the sensor.
Detect gear position in real time
Transmit stable electrical signals
Improve transmission accuracy
Support ECU control logic
Reduce shifting errors
The working principle is straightforward. When the gear mechanism moves, the internal sensing element reacts immediately and converts that movement into an electrical output signal.
That signal is sent through the wiring harness to the control system. The ECU processes it and adjusts engine or motor behavior instantly.
This process happens in milliseconds, ensuring real-time response for smooth and accurate operation.
| Component | Function | Benefit |
|---|---|---|
| Sensing Core | Detect gear movement | High accuracy |
| Signal Module | Convert motion to signal | Stable output |
| Wiring Harness | Transmit signal | Reliable communication |
| Protective Housing | Environmental protection | Long service life |

In real-world applications, even a small signal delay can cause unstable performance. For example, in electric motorcycles, incorrect gear feedback can affect acceleration, torque output, and riding comfort.
That is why SS-01 is designed to maintain stable performance even under vibration, temperature changes, and long-term use.
Smoother gear shifting experience
Improved ECU response accuracy
Reduced mechanical wear
Better driving safety
Stable dashboard display output
We designed the SS-01 based on real customer feedback from motorcycle manufacturers and industrial equipment suppliers. The goal was not just performance on paper, but stable performance in real operation.
Instant detection of gear changes ensures real-time control feedback.
Stable output reduces incorrect gear signals.
Suitable for motorcycles, ATVs, and industrial machinery environments.
Works reliably in both hot and cold conditions.
Built for continuous industrial and automotive use.

In my experience working with industrial sensors, consistency is always more important than complexity. A product can have advanced design, but if the manufacturing process is unstable, performance will vary from unit to unit. That is something we strictly avoid in the SS-01 production system.
Each Shift Sensor SS-01 is manufactured under a controlled process with clear inspection points at every stage. This ensures every unit leaving the factory performs the same way in real working conditions.
Incoming raw material inspection
Precision housing molding
Sensor core assembly
Wiring and connector installation
Signal calibration and alignment
Electrical performance testing
Temperature cycling test
Vibration simulation test
Final appearance inspection
Packaging and export preparation
Only products that pass all testing stages are approved for shipment. This reduces failure risk and ensures stable long-term performance.
Different customers have different mechanical structures, wiring layouts, and installation environments. That is why the SS-01 is designed with flexible customization options.
We work closely with OEM customers to adjust the sensor design without affecting core performance stability.
Connector type selection
Wire harness length customization
Output signal configuration
Mounting structure design
Waterproof level adjustment
OEM logo printing
Custom packaging design
These options help customers integrate the SS-01 directly into their system without additional modification.
Before shipment, every SS-01 must pass a strict quality control process. We do not rely on sampling alone; instead, we test every unit to ensure consistency.
100% functional testing
Signal output verification
Connector strength testing
High-temperature resistance test
Low-temperature performance test
Vibration endurance test
Visual defect inspection
This process ensures that every product delivered to customers meets the same performance standard.
Even a well-designed sensor can fail if it is damaged during transport. That is why packaging is treated as an important part of the product system, not an afterthought.
For SS-01, we use a multi-layer protection structure to ensure safe delivery during international shipping.
Anti-static protective bag
Shock-absorbing foam layer
Inner protective tray
Reinforced export carton
This structure protects the sensor from vibration, moisture, and impact during long-distance transportation.
