If you’ve ever tried to ride a unicycle, most people would agree it’s pretty much impossible. However, with the Enicycle, a motorized unicycle, it’s dirt simple and you can learn in less than 15 minutes. The video above walks you through how it was designed as well as the balancing and steering mechanisms. It has built in gyroscopes and accelerometers (learn how to use a wiimote as a cheap accelerometer) along with microcontrollers and a 100W motor.

• Incredible Balancing, Climbing and Jumping Robots
• Make a Mini Segway with the Arduino

“The mini gyroscopes measure the vertical angle of the bike at a rate of 100 times a second, then feed the data to the processor, which drives the motor and in turn keeps you balance. Sounds complicated? Well, all you have to know is that you just lean forward to go and steer with your feet. Easy. To see just how easy, check out the video” – Featured on Gadget Show.
