The idea is basically an e-bike concept folded around a circular axis.

This is a first project for my major study in industrial design in 2006. I'm still thinking about the problems that I was not able to solve at that time. It is a trail that I am struggling to create a structure that rotates and folds like a Swiss knife based on a central axis. I tried to sketch and find a suitable structure for folding at the same time considering the transmission of power, tilting steering, and the size suitable for human body when unfolded.
