Torque mid-drive motor is a commonly used electric bicycle drive system. It consists of a motor installed near the bottom bracket of the bicycle, which transfers power to the rear wheel through a chain or belt drive. Here's a detailed explanation of how torque mid-drive motors work and their advantages:

Working principle:

1. Power input: The rider generates power by pedaling and transfers it to the mid-drive motor.
2. Sensing and transmission: The mid-drive motor senses the rider's pedal force and speed, determining the required power output and converting it into corresponding torque.
3. Power output: The mid-drive motor transmits the converted torque to the rear wheel through the drivetrain, propelling the bicycle forward.

Advantages:

1. Natural riding feel: Torque mid-drive motors can better simulate the natural riding experience of a traditional bicycle. They provide power assistance based on the rider's pedal force, making it feel more like riding a regular bike rather than relying solely on electric assistance, such as TSDZ2,BAFANG mid motor.
2. Good balance: Due to the motor's location near the bottom bracket, weight distribution is more balanced. This provides improved stability and handling, resulting in a more comfortable and controlled ride.
3. Versatility: Torque mid-drive motors are compatible with various types of bicycles, including mountain bikes, city bikes, and folding bikes. They can be integrated with different gear systems and are easier to retrofit.

In addition, torque mid-drive motors offer advantages such as efficient energy utilization, high reliability, and lower maintenance costs. These factors, along with the design and working principles, have contributed to the widespread use and popularity of torque mid-drive motors in the electric bicycle industry.
