In order to further fine tune your seat position we have made the ASS handle bar foldable. In the most forward position the ASS handle bar is fixed. However, since quite some cyclists prefer to have the handle bar more close to their body, we have made the backward position of the handle bar adjustable. Like many other things on our GreenMachine, you can adjust it according to your own personal riding style.

Finally the stem of the handle bar can be telescopically extended or shortened for any stature height of any cyclist.
