FAQ Motor and complete kit

All questions about our engine and our complete kit.

An electric bike conversion kit is a set of parts that enables you to transform your traditional bike into an electric one. It generally consists of a motor, battery, controller and control screen. The motor can be installed in the hub of the front or rear wheel, but it is preferable to install it on the crankset for better maneuverability and efficiency. The controller manages motor and battery power, while the control screen displays various information in real time.

Yes, our TSDZ2 bottom bracket motor kit can be adapted to many types of bike, including city, mountain, racing and even cargo bikes. The design of our kit makes it easy to install on most bicycle frames without the need for modification. However, we recommend that you check your bike’s compatibility with our kit before purchasing.

Installing the electric bike conversion kit is fairly straightforward if you have the right tools and the necessary knowledge. However, this may vary according to the type of frame and components already in place on your bike. We therefore recommend that you read the compatibility guide carefully and follow the installation instructions included with your kit.

Installing a bike electrification kit may seem complex, but it can be an easy operation if you follow the instructions supplied with the kit. Here are the 3 main installation steps:

  1. remove existing parts such as cranks and bottom bracket,
  2. replace them with the parts supplied in the kit, such as the motor and battery.
  3. Make sure all components are properly secured and test your bike to ensure that everything is working properly.

By choosing to convert your bike to an electric bike, you’re also helping to reduce the electric bike’s greenhouse gas emissions compared with buying a new bike.

The TSDZ2 kit features a central motor for more balanced weight distribution, improved ride feel and more efficient power transmission than wheel-mounted kits. What’s more, this can extend battery life and provide better assistance. We wrote an article about it.

The torque sensor measures the force exerted on the pedals by the rider and adjusts the assistance accordingly (not like on Bafang BBS01 motors). It is more precise than speed or rotation sensors, providing more natural assistance. Accuracy depends on model and build quality, and the TSDZ2 kit sensor is considered highly accurate. Just be careful not to put your feet on the pedals when starting (1 to 2 seconds), to allow the torque sensor to initialize.

The kit comes complete with the motor, battery, charger and display of your choice, as well as everything you need for assembly: screws, cables, cranks, clamps and a special wrench for the main nut.

For assemblyIn order to get the most out of your crankset, you’ll need sets of Allen keys (2.5 mm / 4 mm / 5 mm / 6 mm / 8 mm), a Phillips and flathead screwdriver, a torque wrench (optional), a crank extractor, a bottom bracket removal wrench, cutting pliers, a “removable” Loctite Blue threadlocker and a few extra clamps.

No, the kit is made in partnership with well-known Asian manufacturers (Tongsheng, APT, Wuxi).
