How to remove crank arms from a Bosch eBike motor

Some rainy day workshop ramblings. We got some new crank arms from Miranda to fit to our Urban Arrow Family with the Bosch Cargo Line Gen 4 motor. The Bosch Gen 4 has an ISIS spindle, which is also found on Bosch Gen 2, and some Bafang, Specialized, Brose and Yamaha motors (to name a few). The Bosch Gen 3 has a Mini ISIS spindle which I will also cover here. This method is also suitable for square taper spindles as fitted to some other Bafang, Tongsheng and Ananda motors. Tools required: A small pick An 8mm Allen or hex key A crank puller with removable inner driver - I use the Park Tool CWP-7, An adjustable wrench A torque wrench that can hit 60Nm A suitable 8mm hex key socket 00:00 - Intro 00:58 - Method 1: Crank arm with fixed washer (ISIS Spindle) 05:43 - Method 2: Crank arm with exposed spindle (Mini ISIS Spindle) 10:13 - Method 3: Self-extracting crank bolts (ISIS Spindle) 12:53 - Outro Music: Travel by Lukrembo Sunset by Lukrembo https://freetouse.com/music Our other social media: Instagram: www.instagram.com/cargobikecrew
