Onewheel is a relatively new self balancing product thich combines elements of aerospace and technology with skateboarding and motor sports to create a powered skateboard with only one gigantic wheel.
Inside the hub of the wheel is an advanced electric motor equipped with an ARM processor, the same as in a smartphone, packed with six-axis motion sensors that calibrate thousands of times per second to keep the vehicle balanced. A subtle lean forward will cause it to accelerate, while a lean backward will slow you down. (“The computer makes it easy for anyone, even a first-time rider,” Doerksen says.) The Onewheel can reach a speed of 15 miles per hour and cruise up to 6 to 7 miles on one charge.
