Pedal alarm, short

The short crank arm is designed for users with reduced knee mobility and helps reduce the range of motion in both knees and hips while cycling. By shortening the crank arm, the strain on the joints is reduced, which can make cycling more gentle and comfortable.

Installation:
The original crank arms are removed by first removing the crank bolt and then removing the chain. A puller tool is used for proper removal. The new crank arms are installed and tightened with the crank bolt, after which the chain is reinstalled.

Important:
The installation must be carried out by professional personnel as special tools are required.
