Japan introduces a new model of unicycle. The electric battery-powered device, shaped like a figure eight, is sure to gain popularity around the world due to it simplisity.
A unicycle is a one-wheeled human-powered vehicle. Unicycles are similar to, but less complex than, bicycles.
Usual unicycles are composed of a few key parts: the wheel (which includes the tire, tube, rim, spokes, hub and axle), the cranks, pedals, fork-style frame, seatpost, and saddle (the seat of the unicycle). The wheel is usually similar to a bicycle wheel with a special hub designed so the axle is a fixed part of the hub. This means the rotation of the cranks directly controls the rotation of the wheel (called direct drive). The frame sits on top of the axle bearings, while the cranks attach to the ends of the axle. The seatpost links the frame to the saddle.
There are many different types of unicycles, which can include (but are not limited to): freestyle unicycles, trial unicycles, MUnis, giraffes, and long distance unicycles, which all have special components unique to that type of unicycle.
The new unicycle unit U3-X, produced by Honda Motor Co, can be steered by leaning in the direction the rider wants to go.
The vehicle, which is in the development stage, has a maximum speed of 6 km per hour (3.7 mph) and weighs less than 10 kilos, according to BBC News' report.
