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.
