The Technology Behind Tongsheng's E-Bike Conversion Kit

Tongsheng e-bike conversion kits revolutionize your cycling experience with their innovative torque sensor system, delivering a natural and intuitive feel.

  • Pedal Input: When you start pedaling, the torque sensor, located in the bottom bracket, measures the force you apply to the pedals.
  • Signal Processing: The sensor sends this data to the controller, which calculates the appropriate level of assistance based on your pedaling input and the selected power mode.
  • Motor Activation: The controller sends a signal to the motor, located in the middle of the bike frame (mid-drive), to provide the calculated amount of assistance.
  • Smooth Power Delivery: The motor works in conjunction with your pedaling effort, delivering power directly to the drivetrain, resulting in a seamless and natural riding experience. The harder you pedal, the more assistance you receive.
  • Additional Features: Tongsheng e-bike conversion kits often include additional features such as multiple power modes, walk assist, and customizable settings via a display unit, allowing you to tailor the performance to your specific needs and preferences.

How to Choose the Best Tongsheng Conversion Kit for Your Needs

tongsheng mid drive motor kit

Selecting the perfect Tongsheng e-bike conversion kit requires a bit of self-reflection and understanding your needs.

Step 1: Determine Your Needs

Riding Style

Commuting: If your rides are mostly flat and you prioritize affordability, the TSDZ2 might be a perfect fit.

Leisure Riding: For casual riding on flat terrain or hilly commutes and weekend adventures, consider the TSDZ2B (500W) for smoother shifting under load.

Off-Road & Heavy-Duty: If you crave power and torque for conquering steep hills and off-road trails, the TSDZ8 (500W-1000W) is your best bet.


Flatlands: A lower-powered motor like the TSDZ2 (250W) will suffice.

Rolling Hills: Opt for the TSDZ2 (350W or 500W) or TSDZ2B for extra assistance on climbs.

Mountains: The TSDZ8 (750W) is designed for the most challenging terrain.

Step 2: Mid-Drive or Hub Motor

Mid-Drive Motors

Tongsheng's mid-drive motors, such as those in the TSDZ2, TSDZ2B, and TSDZ8, provide better weight distribution and use your bike's gears for improved performance on varied terrain. These are ideal for riders seeking efficiency and balance.

Pros Cons
Better weight distribution, leading to improved handling and stability Installation can be more complex as you need to replace the crankset
More efficient power transfer, resulting in better hill-climbing ability More expensive than hub motors
More natural riding feel, as the motor works in conjunction with your gears May require more frequent maintenance due to the system's complexity

Hub Motors (Front or Rear)

Alternatively, for an easier installation and maintenance process, a hub motor conversion kit may be a better option. Although Tongsheng specializes in mid-drive systems, hub motors are a quiet and simple option.

Pros Cons
Easier installation, especially for front hub motors May struggle on steep inclines
Lighter weight due to fewer components Feel less intuitive than a mid-drive's pedal-assist, as the motor powers the wheel directly
Typically more affordable than mid-drive motors Increase wear and tear on the rear wheel components

Step 3: Desired Range

Battery capacity (measured in ampere-hours, Ah) determines your range. If you have longer rides, choose a battery with higher Ah.

Step 4: Assess Your Bike's Compatibility

Ensure that the conversion kit is compatible with your bike's frame. The Tongsheng TSDZ2 and TSDZ2B are designed to fit most standard bike frames, while the TSDZ8 is suitable for more robust frames.

Step 5: Budget & Value

Determine your budget and find a Tongsheng conversion kit that offers the best value for your money. The TSDZ2 is an excellent entry-level option, while the TSDZ8, with its higher power and additional features, may require a larger investment.
