Although zero-wheeled hoverboards are still not a reality for some reason in the 21st century, this cool new SBU V3 at least gets personal transport vehicles down to one. Forget pedals and handlebars because this is an electric self-balancing unicycle designed to carry a rider to a top speed of 15 mph for up to 10 miles using nothing but simple natural leaning motions. After about 20 minutes of practice, it will feel like second nature to simply lean forward to move forward, lean back to slow down or come to a stop and lean side to side to turn. I could get into all the performance and safety features, but it's just easier just check out the video below to see it in action. Yep, a cool unicycle now exists!
