The BLUECHAIN Chain Wizard crank helper for e-bikes enables the e-bike chain to be turned backwards while the bike is stationary. This allows simple maintenance and lubrication work to be carried out quickly and easily.

Our BLUECHAIN Chain Wizard is simply attached to the crank arm on the drive side and the pin is placed in the spider of the chainring. If you now turn the crank backwards, the chainring also turns and the chain is in motion. The BLUECHAIN Chain Wizard is suitable for the most common e-bikes with mid-drive motors.
