Prone bicycle

A type of bicycle where the rider lies in a prone position

A prone bicycle is a type of bicycle designed to be ridden in a prone position, where the rider lies face down, as opposed to the more common upright bicycle or recumbent bicycle positions. This design offers unique aerodynamic advantages and can be more comfortable for some riders, although it is less common than other bicycle types.

Design and Features

The prone bicycle positions the rider in a horizontal, face-down posture. The rider's body is supported by a padded platform, and the legs extend backward to reach the pedals. The handlebars are positioned in front of the rider, allowing for steering and control.

The design of prone bicycles can vary, but they typically feature a long wheelbase to accommodate the rider's extended body. The frame is often constructed from lightweight materials such as aluminum or carbon fiber to enhance speed and maneuverability.

Aerodynamics

One of the primary advantages of the prone bicycle is its aerodynamic efficiency. By positioning the rider in a horizontal posture, the frontal area exposed to wind resistance is minimized, potentially allowing for higher speeds compared to traditional bicycles. This makes prone bicycles particularly appealing for time trials and speed record attempts.

Comfort

While the prone position can be more aerodynamic, it may not be as comfortable for all riders. The face-down posture can place strain on the neck and back, and the visibility is reduced compared to upright bicycles. Riders may need to adjust to the unique handling characteristics of prone bicycles, which differ from other bicycle types.

History

The concept of the prone bicycle dates back to the early 20th century, with various inventors experimenting with different designs. However, it has remained a niche category within the broader cycling community. Interest in prone bicycles has persisted among enthusiasts and innovators seeking to push the boundaries of bicycle design and performance.

Applications

Prone bicycles are primarily used in specialized cycling events and by enthusiasts interested in unique bicycle designs. They are less common in everyday cycling due to their unconventional posture and handling characteristics.
