The Bosch crank arm puller tool is a must-have for anyone wanting to do maintenance to their Bosch equipped electric bicycle. Works with all versions and model years. Simply insert the tool into the threaded spindle and the tool will easily pull off the crank arm safely and damage-free. Works with all Bosch e-bike drive systems. The Bosch crank arm puller tool is designed to remove crank arms from splined Drive bottom bracket spindles that do not use a self-extracting system. The finely machined threads provide leverage to remove tight crank arms and a strong rotating tip ensures long life and smooth extraction. NOTE: Never attempt to pull off your crank arm on a Bosch-equipped drive system without using this tool as damage will occur if you do not use a tool like the Bosch crank arm puller tool.
