To find out if the engine will fit on your bike, use a ruler and take a photo  of  length of the axis of the center movement of your bike like these. Thus, we can easily guarantee the engine's compatibility.

​

The default is 68 to 73mm. If your bike has this measurement, the traditional BBS02 (500 and 750W) and BBSHD (1000W) engines, in addition to the TSDZ2, will do.

​

If the shaft is 100mm, you need the BB100 motor we have in the 750W version.
