TREKKING Conversion Kit for Bicycle 250W / 1200W MID TSDZ8
The TSDZ8 is a high-performance mid-drive motor (MID Drive) with a power output of 250W / 1200W, ideal for converting a bicycle into an electric bike. Thanks to its torque sensor, it provides natural pedal assistance, making the ride more intuitive and comfortable. The TSDZ8 conversion kit performs отлично in urban conditions, offering support across various terrains. It’s an ideal choice for those looking for an efficient solution to transform a traditional bicycle into an electric one.
An electric bike is one of the cheapest forms of transport. How much does it cost to travel 100 kilometers on an electric bike? Taking into account average component wear, battery lifespan, and electricity prices, the cost for such a distance comes to… around €0.20–€0.30.
What’s included in the kit?

- Advantages of a mid-drive motor kit:
Advanced sensor system: The TSDZ8 motor is equipped with torque and speed sensors that analyze how much force the rider applies while pedaling. As a result, the motor assistance adjusts to the user’s needs, making the ride more natural and intuitive.
Quiet operation: Thanks to brushless technology, the TSDZ8 motor operates very quietly. This is important not only for riding comfort but also for users traveling in urban areas where noise can be an issue.
High energy efficiency: The motor features high efficiency (>85%), which translates into longer range and lower energy consumption during rides. This allows cyclists to enjoy longer distances without worrying about quickly draining the battery.
Versatility: The TSDZ8 is compatible with various types of bicycles, including mountain, trekking, and city bikes. Its flexibility allows users to tailor the drive system to their individual needs and riding preferences.

Due to the nature of geared motors, the TSDZ8 drive kit is not intended for professional use, such as courier work. For this purpose, a direct-drive (gearless) motor is recommended.
Spare parts are also available in the store’s offer, such as gears (38T and nylon), motor stator and rotor, torque sensor, crank arms, and a controller. This allows for easy maintenance and extends the lifespan of the set. Click here
