A pivoting-boom front-wheel drive (PBFWD aka moving bottom bracket recumbent) configuration also overcomes heel strike since the pedals and front wheel turn together. The small front wheel and large rear wheel combination is used to keep the pedals and front wheel clear of each other, avoiding the problem on a short wheelbase recumbent called 'heel strike' (where the rider's heels catch the wheel in tight turns).

One common arrangement is an ISO 559 (26-inch) rear wheel and an ISO 406 or ISO 451 (20-inch) front wheel. Another advantage of both wheels being the same size is that the bike requires only one size of inner tube. High-racer aficionados also claim that they are more stable, and although it is easier to balance a bicycle with a higher center of mass, the wide variety of recumbent designs makes such generalizations unreliable. Larger diameter wheels generally have lower rolling resistance but a higher profile leading to higher air resistance. Given the higher rolling resistance of the smaller front wheel, loss of steering and control are somewhat more likely attempting sharp or quick changes of direction while crossing over patches of loose dirt, sand or pebbles. The front wheel is commonly smaller than the rear, although a number of recumbents feature dual 26-inch (ISO 559), 650c (ISO 571), 700c (ISO 622), or even 29 x 4' oversize all-terrain tires. The rear wheel of a recumbent is usually behind the rider and may be any size, from around 16 inches (410В mm) to the 700c (or 27' on some older models, as on upright road bikes of that time) of an upright racing cycle. Within these categories are variations, intermediate types, and even convertible designs (LWB to CLWB) вЂ“ there is no 'standard' recumbent. Long-wheelbase (LWB) models have the pedals located between the front and rear wheels short-wheelbase (SWB) models have the pedals in front of the front wheel compact long-wheelbase (CLWB) models have the pedals either very close to the front wheel or above it. Long-wheel-base low-rider recumbent with steering u-joint (UA) A variant with three wheels is a recumbent tricycle. Recumbents are available in a wide range of configurations, including: long to short wheelbase large, small, or a mix of wheel sizes overseat, underseat, or no-hands steering and rear wheel or front wheel drive. A recumbent holds the world speed record for a bicycle, and they were banned from racing under the Union Cycliste Internationale (UCI) in 1934, and now race under the banner of the World Human Powered Vehicle Association (WHPVA) and International Human Powered Vehicle Association (IHPVA). Most recumbent models also have an aerodynamic advantage the reclined, legs-forward position of the rider's body presents a smaller frontal profile.

On a traditional upright bicycle, the body weight rests entirely on a small portion of the sitting bones, the feet, and the hands.

Most recumbent riders choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by back and buttocks.
