The funny thing is that Ninebot (the company that bought Segway) has been making single-wheeled devices since at least 2014.  They&#x27;re quite a bit nicer than either of the devices mentioned in this article and can be had for $800-900.<p>I only know because I did some halfassed window shopping for them before deciding that however fun they looked, I wouldn&#x27;t really be able to ride one anywhere in town legally so it would end up being a pretty expensive toy to ride around the park with.<p>(current example:  <a href="http:&#x2F;&#x2F;www.ninebot.com&#x2F;ninebot&#x2F;NinebotOne&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.ninebot.com&#x2F;ninebot&#x2F;NinebotOne&#x2F;</a>)
