>>1725701IMHO they're much more fun than the big skinny wheel electric unicycles. But because onewheel has a design patent that they aggressively defend, they're the only thing like this on the market - so if you like customizing or buying sketchy cheap shit off aliexpress, there aren't a lot of other options out there.
If you're going to use it daily/regularly for commuting and aren't stoked about getting plastic surgery in the future, wear a full-face helmet.
The folks around here who are serious about commuting on these inevitably gravitate towards full motorcycle leathers. That probably tells you something about the inevitability/frequency of road rash incidents.
