To find the right tuning kit, first you'll need to know which motor powers your bike. Here's how to find out.
Step 1: Find Your Motor Type
Your bike's motor (sometimes called the "drive unit") is made by a company like Bosch, Shimano, Specialized, or Giant.
To find yours:
-
Check your bike's app – If your bike connects to a phone app (like Bosch eBike Flow or Shimano E-Tube), the motor info is usually shown there.
-
Search online – Google your bike's make, model and year followed by "spec". For example: "Cube Stereo Hybrid 2025 spec". The motor will be listed under "Motor" or "Drive System".
Common motors we see:
-
Bosch Smart System Gen5 or Gen4 CX
-
Bosch Gen4 (non smart system)
-
Shimano EP8 / EP800
-
Yamaha PW-X3
-
Brose Specialized 2.2 or 2.1 motors
-
Giant SyncDrive Pro2

Optional step for Bosch Motors only – Check for a Rim Magnet
If your bike has a Bosch motor as was manufactured after 2024, we also need to know if it has a rim magnet sensor.
This is a small module attached to the rear wheel valve (or hidden inside the rear tire.
Have a look and let us know if you can see one – this helps us recommend the right kit variant.
