1. Bottom bracket width
   As this motor is available for different bottom bracket widths, you should measure this on your bike beforehand and select it accordingly above. To do this, we recommend turning the bike over and measuring the frame width at the bottom bracket. In the picture on the right you can see the bottom bracket from below. The remaining frame width is measured (68 mm in the picture).
2. Bottom bracket diameter
   The motor axle has a diameter of 33.4 mm and is installed in place of the bottom bracket. If your bottom bracket width is more than 75 mm, it is possible that the diameter of your bottom bracket is larger (press-fit bearing). Check here whether you have installed a press-fit bearing. If you are not sure – just give us a call, send us a photo of your bike or send us an e-mail (welcome@fasterbikes.eu) and we will help you! We recommend that you remove the bottom bracket so that you can easily measure the diameter:
   • Result: 33/34 mm – BSA bottom bracket with thread
   • Result: 41/42 mm – BB92 bottom bracket without thread
