How to check the wheelbase of your FAT BIKE ?

To check the rear wheelbase of your fat bike in order to transform your fat bike into an electrically assisted bike, you have to measure the distance between the frame and the rear wheel, you will also find this information on the bike’s technical sheet.

If the measurement is 170mm you will need a long shaft.

If the measurement is 190mm you will need an extra long shaft.

(for information on a classic bike the center distance is 135mm to 150mm, you will need a standard length axle)
