- If your kit includes brake levers and a thumb throttle, do not tighten the display bolts completely yet.
- Attach the thumb throttle and brake levers under the display.
- Connect the brake levers to the outer sockets and the thumb throttle to the middle socket on the display.
- Secure the Wiring
- Route the display cable along the down tube of your bicycle.
- Secure the cable with cable ties and connect it to the corresponding cable on the motor.
Step 3: Installation of the Speed Sensor
- Mount the Sensor
- Attach the speed sensor to the left side of your bicycle frame.
- Ensure the cable from the sensor is directed towards the motor.
- Align the Magnet
- Fix the magnet to one of the spokes of the rear wheel.
- Align the magnet with the sensor, ensuring it passes through the marked area on the sensor when the wheel rotates.
- Adjust and Secure
- Adjust the sensor and magnet position as needed to avoid contact.
- If space is tight, remove the sensor from its mount and attach it directly to the chainstay with cable ties.
- Connect the Sensor
- Connect the speed sensor cable to the yellow cable from the motor.
Step 4: Electrical Connections
- Connect the Battery
- If using a bottle battery, mount the battery holder on the down tube, possibly drilling new holes if the existing ones do not align.
- Install rivet nuts if necessary and secure the holder with screws.
- Connect the battery to the motor.
- Power Up the System
- Once all connections are secure, turn on the battery.
- Power on the display by pressing the power button.
- Check that all components are functioning correctly.
Step 5: Operating the Display
- Powering On and Off
- Press the power button to turn on the display. The backlight will briefly illuminate.
- Press and hold the power button to turn off the display.
- Using the Display
- The default assistance level is the lowest. Use the + (plus) button to increase and the – (minus) button to decrease the assistance level.
- There are four assistance levels: ECO, TOUR, SPEED, and TURBO.
- To use the bike without motor assistance, press the – (minus) button repeatedly until the assistance indicator disappears.
- The display shows ODO (total distance), TRIP (trip distance), AVG (average speed), and TIME (ride time). Toggle between these by pressing the mode button.
- Calibration
- Keep both feet on the ground when powering on the display to ensure correct torque sensor calibration.
Troubleshooting Your TSDZ2B E-Bike Motor Install
Installing a Tongsheng TSDZ2B e-bike conversion kit can be straightforward with the right tools and preparation, but here are some additional tips and common issues you might encounter.
TSDZ2B Installation: Pro Tips for a Flawless E-Bike Conversion
- Prepare Your Bike
- Clean your bike thoroughly, especially the bottom bracket area, to ensure there is no dirt or debris that can interfere with the installation.
- Check that all parts and tools are available before starting the installation.
- Test Fit Components
- Before fully installing, do a dry run by loosely fitting all components. This helps in understanding how everything fits together and identifying potential issues.
- Lubrication
- Apply a thin layer of grease on the bottom bracket shell and motor axle to facilitate smoother installation and prevent corrosion.
- Cable Management
- Plan your cable routes before securing them. Avoid committing to a route for one cable until you have mapped out all cables to ensure they do not interfere with each other.
- Use staggered connectors when connecting battery cables to reduce the risk of shorting and to facilitate easier application of heat shrink for waterproofing.
- Battery Connection
- Always connect the cables from the battery mount to the motor without the battery in place to avoid sparks. Consider using a junction box for a more waterproof connection instead of relying solely on electrical tape.
- Ensure the battery mount is secure. If you’re drilling new holes, measure carefully to align the mount correctly.
- If using a bottle battery, make sure it does not interfere with other components on the frame.
- Torque Sensor Calibration
- Ensure that the torque sensor is calibrated correctly by keeping both feet on the ground when powering on the display. This avoids false readings and ensures accurate motor assistance.
- Tightening Bolts
- Tighten all bolts to the manufacturer’s recommended torque specifications to prevent damage to components and ensure safety.

Common Installation Problems & Solutions
Every TSDZ2B installation comes with its own quirks. Here’s a troubleshooting guide to help you tackle common issues.
| Problem | Description | Solution |
|---|---|---|
| Motor Fitment Issues | The motor axle does not fit through the bottom bracket. | Ensure the bottom bracket shell is clean and free of debris. Check if the bottom bracket width is within the specified 68-73mm range. If necessary, lightly file the inner edges of the bottom bracket shell. |
| Speed Sensor Malfunction | Speed sensor shows incorrect readings or displays zeros. | Check the alignment of the magnet and sensor. Ensure that the sensor is positioned correctly and not too far from the magnet. If the problem persists, consider insulating the connector with heat shrink tubing to protect against cold temperatures. |
| Controller Overheating | Motor controller overheats during prolonged use, especially on steep hills. | Avoid extended high-load usage and give the motor breaks during long climbs. Consider upgrading to the latest TSDZ2B model which has improved internals to handle heat better. |
| Water Ingress | Water entering the motor or electrical components. | While the TSDZ2B is water-resistant, it is not fully waterproof. Avoid riding in heavy rain or through deep puddles. Use waterproof connectors and apply silicone sealant to vulnerable areas. |
| Battery Mount Fitment | Battery mount holes do not align with the frame. | Measure and drill new holes if necessary. Use rivet nuts for secure mounting. Ensure the battery mount is securely fastened and does not interfere with other bike components. |
| Display Issues | Display does not turn on or shows error codes. | Check all electrical connections, ensuring they are secure and properly aligned. Verify that the battery is charged and connected correctly. Inspect the display connector for any bent pins or damage. Refer to the display manual for specific Tongsheng error codes and their solutions. |
| Crank Arms Wobble | The crank arms feel loose or wobble after installation. | Recheck the M33 nut and ensure it is tightened correctly using the provided wrench. Verify the crank arms are securely attached to the motor axle and bolts are torqued to specification. |
| Torque Sensor Calibration | Inconsistent power output from the motor. | Ensure the bike is stationary and the rider is not pressing on the pedals when powering on the display. This allows the torque sensor to calibrate correctly. |
| Throttle Not Working | The thumb throttle does not activate the motor. | Verify that the throttle is properly connected to the display. Ensure the throttle function is enabled in the display settings. Check the wiring for any damage or loose connections. |
| Speed Sensor & Magnet Misalignment | The magnet does not align properly with the speed sensor. | Adjust the position of the sensor and magnet. If necessary, mount the sensor directly on the chainstay with cable ties for a better fit. |
| Unresponsive Assistance Levels | Changing assistance levels does not affect the motor’s performance. | Ensure the display and motor are correctly connected. Recalibrate the torque sensor by keeping both feet on the ground when powering on the display. Check the settings on the display for correct configuration. |
| Loose Motor | The motor feels loose even after tightening the M33 nut. | Recheck the installation of the mounting bracket and ensure the M33 nut is properly tightened using the provided wrench. You may also use thread locker on the nut for extra security. |
