Recumbent bicycles have been in production for decades, with a history stretching back to the 19th century along with its more familiar bicycle brethren.
Recumbent bikes place the rider in a more horizontal position with more framing and a larger seat, with the alloy frame extended between the larger wheelbase to position the rider directly between the wheels and lower to the ground. They work by the rider pedaling either the front or rear wheel.
Steering is controlled using extended handlebars directly above the seat from the front fork, or indirectly via cables and rods for under-seat systems. A recumbent bicycle boasts several advantages over a traditional bicycle.
First, the laid-back body position means that the rider is more comfortable, as body weight is more spread out and not merely cantered on the bones in the buttocks.
Second, a recumbent bicycle can have better aerodynamics, as the reclined, legs-forward position ensures a smaller frontal profile, reducing drag.
It has disadvantages though including maneuverability, as a recumbent bike can have a large turning radius as a result of its wheelbase, and poor visibility on busy roads.
