õhuratas

Õhuratas is an Estonian term that translates to "air wheel" or "air bicycle" and generally refers to a self-balancing unicycle. It is a personal transportation device that uses a gyroscopic system to maintain balance. The rider stands on two footplates, one on either side of a single large wheel. Propulsion and steering are controlled by the rider's subtle shifts in weight and body position.

These devices typically operate on electric power, rechargeable via a standard electrical outlet. Their compact size and maneuverability make them suitable for short to medium-distance travel, often in urban environments. The learning curve for riding an õhuratas can be steep, requiring practice to master the balance and control. Safety gear, such as helmets and pads, is often recommended for riders.

Õhuratas technology shares similarities with other self-balancing personal transporters like hoverboards and electric unicycles, though the distinct single-wheel design is a defining characteristic. They are a relatively modern invention, gaining popularity in recent years as alternatives to traditional bicycles or scooters. The design emphasizes an intuitive, almost fluid connection between rider and machine.
