Here is another unicycle for you, something that looks like a compromised Segway. Thanks to gyroscopic sensors, people who make use of the SoloWheel Gyroscopic Electric Unicycle can be assured that they will be balanced without the need for usual handles that bikes are known to have. Slight feet movements while wearing the said sensors are all that is needed and by just leaning forward, steady acceleration occurs.
The SoloWheel comes with a 1Kw electric motor which can accommodate up to 250lbs. It can get top speeds of 10MPH thanks to a lithium ion battery that is good for up to 2 hours of use.
