How To Loosen The Crank On A Bike?

Remove the crank bolt or nut from the crank. When you do this, the crankset and bolt become free, allowing you to remove them with relative ease. This can be accomplished by twisting the bolt or nut in a counter-clockwise manner.

Insert an Allen key into the crank bolt and spin it counterclockwise until the crank is fully extended. To loosen the crank bolt, turn the Allen key handle in the opposite direction of the clock.
