Steel Frame

Manufactured in Germany

We dimensioned and geometrized our innovative Urwahn steel frame in consideration to the area of use. The technical form and the ergonomic suitability of the steel frame are balanced to the th aesthetic shape. Both attributes related to the humans in their role as users.

The result is a compact geometry characterized by agile driving behaviour, directional stability, improved traction and reduced steering forces.

MEASURE YOUR STANDOVER

Take a spirit level and clamp it between your legs. Move the spirit level upwards your crotch as if you would sit on a saddle and balance the level spirit level parallel to the ground. Next, measure the distance from the ground to the top edge of the spirit level.

IMPORTANT: please make the measurements with shoes on.
