The Electric UniCycle, or the EUC for short. Once mastered, becomes THE perfect solution for daily commutes ranging from 1 to 15km. It comes in a nice, ~13kg package and is AWESOME!
An awesome feat of engineering that the EUC is, brings a lot of joy, tons of convenience, loads of steep learning curves for starters and a bit of frustration, eventually. All in all, the pros vastly outnumber the cons. Did I mention FUN? You get that as a bonus.
If you wonder how it works, it essentially boils down to “not letting you fall”.
