Adjusting the saddle height

Kwiggle is built for people between 1.35 m and 1.95 m (4 ft 5 in and 6 ft 5 in) in body height. 

To get a perfect riding position you only have to turn two screws, one  adjusts the saddle height and the other the distance of the saddle to the steering wheel.

You only need to set it this once because the Kwiggle remembers your adjustments even after folding and unfolding. The Kwiggle always folds to the same small size independent of saddle height.
