Going uphill you can climb unrestricted, with hands and senses free, then swoosh back down to valley level either standing or kneeling according to the terrain!
The Bergmönch backpack bike combines a number of my passions in a single product; great design, bags and cycling all in one. The bike is designed to be light and compact for carrying up hills for long distances. When you reach the top you unfold the bike, get on, and using the downward momentum of the hill you are quickly propelled to the bottom. It would be a great way to hit the ski slopes in summer. The backpack itself has room for a helmut and food for when you reach the top. The bike has no pedals or seat making other uses impractical for most but it’s an interesting design nonetheless.
