The Self Balancing Electric Unicycle

This is the briefcase-sized electric unicycle that keeps a rider perfectly balanced at all times with gyroscopic sensors. Equally suited for urban commuting and suburban recreation, the unicycle requires a rider to merely stand on its two folding feet pads; gyroscopic sensors detect a rider's subtle feet movements while accounting for a shoulder-slung backpack or bag for its center-of-mass calculations. Gripping the handlebar and leaning forward results in steady acceleration without jolting, while leaning backward brings the unicycle to a slow, steady stop. A rider controls side-to-side balance and turning with subtle leaning. The unicycle's 500-watt electric motor propels a 160-lb. rider up to two hours at 13 mph with a three-hour charge of its built-in lithium-ion rechargeable battery. Housed within a sturdy ABS case, the motor spins the cycle's single 16" diameter wheel that extends only 4" from the case, so pant legs won't snag. Its knobby tire grips surfaces while providing minimal rolling resistance for smooth rides. Includes AC adapter. Supports up to 250 lbs. 25" L x 12" W x 23" H. (57 lbs.)
