Folding bikes are already pretty convenient, but the fact that the Bergmoench backpack bike folds straight into a backpack is even better. This bike is shown for outdoor adventures, and there is a reason. With no pedals to propel you forward and no seating, it was made strictly for a mountainside ride. If not for those minor details, I would have seriously considered getting one for myself.
Lightweight enough to carry around on your back, compact enough to travel around the city, and sturdy enough to ride on dirt paths, what more can anyone ask for? But the idea for the Bergmoench backpack bike is to have “users will climb a hill and roll down on the bike in a more upright position.” There aren’t enough hills in the city, unfortunately.
