Honolulu Halfpipe

When you're sitting up here in your tire, you can't see the route you're about to take. Therefore, take all your courage together and then it goes down almost vertically, only for it to go steeply uphill again on the other side. Then follows the backward fall and so it goes back and forth until you are balanced!

Hints:
Height restriction: from 1,22m
