Monocycles: The One-Wheel Wonders

Monocycles, also known as one-wheel motorcycles, are unique vehicles that offer a different kind of riding experience. With only one wheel on the ground, this bizarre vehicle can make for an exciting - if precarious - way to get around.

1. Understanding the Monocycle

A monocycle is a vehicle where the driver sits upright inside a large wheel frame made of an alloy. This frame spins the larger outer wheel, which comes into contact with the ground and typically has a tire mounted on it. The outer wheel is spun via smaller wheels attached to the inner frame.

2. Powering the Monocycle

While small petrol engines are most commonly used in today’s monocycles, non-motorized versions, often referred to as monowheels, also exist. These are propelled by pedals, a chain, and some good old-fashioned legwork. However, due to the vehicle’s precarious balance, even motorized monocycles can typically only reach top speeds of around 40 kilometers (25 miles) per hour.

3. Steering and Balance

Steering a monocycle involves the driver leaning from side to side. Dragging a foot can create friction, slowing down one side of the monocycle and providing a tighter turning circle for better cornering. However, maintaining balance in a one-track vehicle with just one point of contact with the ground presents challenges regarding stability.

4. Visibility and Capacity

Visibility is another issue with monocycles. With the driver sitting inside the wheel, the view straight ahead is severely restricted. Furthermore, monocycles have only been successfully designed for single occupancy, limiting their capacity.

5. The Future of Monocycles

Despite these challenges, monocycles continue to intrigue inventors and enthusiasts alike. For instance, American inventor Kerry McLean has built over 25 different variations of his version of the monocycle. As technology advances, we may see improvements in monocycle design that could make them a more viable mode of transport.

In conclusion, while monocycles may not be widespread modes of transport due to their inherent challenges, they certainly offer a unique and fascinating approach to personal mobility.
