To be fair, this compact mode is more akin to a Segway than a unicycle. Still, you might ask why it's necessary to make a relatively unsafe motorcycle even more so.

Plus, it’s battery-powered, meaning it won't produce any noxious fumes. That's something your fellow elevator passengers would appreciate.
