The Woom Crank

We develop smart standards

The length and spacing of our crank are adapted for a child's body.  With an optimal Q-factor, our crank provides multiple benefits.

• Ergonomic length ensures a perfect fit (B) 
• Low, child-friendly Q-factor ('Q-Faktor'): horizontal leg spacing suitable for the pelvic width: 141 mm (5.6 inches). 

• Crafted with super-light aluminum
• Integrated chain ring
• Chain-protection ring prevents pinching and protects the pants

The length of the crank fits the length of the legs.
