How do you know this kit will fit your bike?

Measure the width of your bottom bracket between the pedals to measure your BBS width, as seen below. The inner diameter of the frame bracket should be not less than 33.5mm. If you have a recumbent bike or trike follow the same measuring process as these kits fit those bikes and are very popular for those applications as well. 

68mm OR 2" 11/16th looks like this:

73mm OR 2" 7/8th looks like this:

The standard kit will fit 68-73mm wide frames. If you have a wider frame of 100mm or 120mm check out the BBSHD 1000W kit which comes in those sizes.

 

Fitment Checklist:

1 - Check that there is a 68-73mm (2.6-2.8 inch) gap in your bottom bracket between the pedals. 
2 - Check your frame size to ensure the frame-mount battery will fit (
L368mm x W90mm x H113mm) (L14.4" x W3.5" x H4.4")
3 - Choose mechanical brakes with sensors (standard) or hydraulic brake sensors. 
4- Choose your chain ring: 44T offers the most low-speed acceleration and torque, 52T offers the highest speed. 46T is standard and ideal for a mix of hills and flat terrain and everyday riding. Please leave us a note when placing your order for the type of chain ring you'd like!
