733:"Weather" protection includes cold and wet, but also shading from sun. Since the rider is doing work, it is typically desirable to have at least some cooling. Many velomobiles have vents and ducts which allow cooling while keeping out water; and the ducts/vents may be closed or covered in cold weather so the rider can stay comfortable even without a secondary heat source. In warm and hot weather, the fairing provides sun protection, but blocks the rider from cooling air, and so may be much warmer for a given level of effort. In some situations, a rider's power output (for any type of cycle) is limited by body temperature, and the worse cooling of a velomobile can limit the rider's power output more than on an unfaired cycle. With an aerodynamic fairing, the velomobile rider at reduced power output may still be faster than an unfaired cycle, due to the lower aerodynamic drag. 779:
the rider. A common way to describe aerodynamic drag is "CdA"; in one comparison of racing cycles, there were several two-wheel streamliners with less than half the CdA drag of the best three-wheeler. Air drag is most significant for high-speed events; as of 2016, the world record for a 200-metre sprint on near-level ground is about 145 km/h for a two-wheel streamliner and about 120 km/h for any vehicle with more than two wheels, meaning the two-wheel vehicle was about 20% faster. Aerodynamic power is roughly cubic in speed, so at lower speeds the difference is much less pronounced. At the same time, two-wheel streamliners require a way to stay upright when stopped and at very low speed, and are more sensitive to blowing over in cross-winds. These factors limit the use of streamliners, despite their aerodynamic advantage.

of entry/exit, comfort, and other "practical vehicle" attributes are reduced. By analogy, many automobile makers make performance cars with limited seating and cargo and worse emissions and fuel economy. In contrast, other velomobile designs sacrifice performance features in order to improve cost, entry/exit, comfort, carrying capacity, and so on. By analogy, many automobile makers offer cargo vans. As of 2017, individual makers sometimes offer models spanning a range of features—for example, there are Milan models used in racing but also a Milan "cargo" model with enough luggage volume to carry a (not-pedaling) human passenger and other bulky items.
570: 741:
there is an additional incentive to make the velomobile narrow. The narrowest velomobiles are only slightly wider than the rider's shoulders, and so the width approaches that of an upright bicycle. However, an upright bicycle still has a significantly narrower "useful" width, as the road contact is in the center and so the rider's hands/elbows/etc. might overhang the edge of the roadway or path without causing problems. In contrast, the wheel track of a velomobile is very nearly as wide as the vehicle itself, and so cannot overhang the edge.

enable use of a fairing which in hot weather can be converted to a canopy. A canopy provides no aerodynamic benefits, but improves cooling compared to a faired configuration, while also reducing sun exposure compared to riding without a canopy. Thus, a "high speed" velomobile may benefit most from better aerodynamics, even when aerodynamics hurts rider cooling; while at the same time a "high load" velomobile may benefit most from improved cooling (to maximize power output) even if that hurts aerodynamics.
737:
the rate of abrasive wear on the drivetrain—including chain and sprockets, but sometimes also derailleurs. The fairing of a velomobile tends to limit both the amount and the kinds of grit landing on the drivetrain. Some cycles use tooth-belt drive, which is less affected by grit, is quieter than a chain, and may be lighter. However, belts are only available in pre-selected sizes. Many recumbent cycles, including most velomobiles, have a long drivetrain for which no suitable tooth belts are available.

and durability, and can also reduce weight. Body-on-frame construction allows flexible configuration: the body may be of any construction, as it does not need to be self-supporting, and various bodies can be used with various frames. Also, the body may be removed so the cycle alone can be used. However, the overall weight of body-on-frame is often higher than alternatives, as the body does have some intrinsic strength, yet this is not used to reduce the weight of the frame.

motors (like eZee, Heinzmann, Bafang, BMC, etc.) and direct-drive hub motors (like Crystalyte, BionX, 9Continent, etc.) but mid-drive units (like Sunstar, Cyclone, Ecospeed, etc.) are used as well due to design constraints in velomobile models with one-sided rear wheel mounting like the Quest, Strada and Mango or front wheel drive in the Velayo, or better efficiency by using the multiple speeds of the chain drive or internal geared hubs (e.g. Rohloff 14 speed hub).

kilograms compared to other designs. A wide range of fibers may be used, but those which reduce weight while retaining strength and toughness often increase the price significantly—e.g., a premium of 1000 Euros to save 3 kg. In addition, it is often hard to segregate and recycle the FRP materials. But despite the cost and other issues, the aerodynamic and weight advantages mean that (as of 2017) monocoque FRP is a common way to build velomobiles.
606:, which is the approach used in most cars. A second alternative is to use a pair of ratchets, where the slower wheel is driven and the faster wheel coasts. Rear drive often uses "idler" pulleys to route the chain; front-wheel drive can eliminate idlers, so offers less friction and also less weight. It can also increase luggage capacity. However, front drive with two front wheels uses some non-standard components, and as of 2017 is used only rarely. 851:" in yet a third. Similarly, going from 3 wheels to 4 wheels can change the category of an otherwise identical vehicle. One reason for the varying treatment is that many laws are older than widespread use of power-assisted velomobiles and so the laws were not written to consider such vehicles. In some areas, laws are being rewritten to include power-assist velomobiles and to harmonize treatment with nearby laws. 554: 466: 420: 36: 498: 374: 562: 346:; some are home-built. Some models have the operator's head exposed; this has the advantage of giving the operator unobstructed vision, hearing, and some cooling, with the disadvantage of being potentially more exposed to weather and less aerodynamic. Fully enclosed machines can suffer from heat or humidity issues as well as potential noise issues. 791:
but more expensive materials. Also, production volumes are low, so for both parts and labor there are not benefits of mass production—as of 2017, many velomobile makers have yearly production on the order of tens or maybe a few hundred velomobiles. Taken together, these factors mean velomobiles are often much more expensive than other cycle types.
622:. The C5 was a delta trike (one front, two rear wheels) with electric assist designed to be mass-produced and sold for a low price. The C5 was poorly designed; it was heavy, had only one gear and had no adjustment for the distance between the pedals and the seat, which is important to get a comfortable pedalling position. 416:, and because the wire/tube support outline shows through once the fabric is tight. Some disadvantages of this approach are the cost of construction, due to the many interconnected supports; and that the shape is that of many flat panels, which limits smoothness of the skin and thus limits the aerodynamics. 823:
Some velomobiles have been converted to provide electric assist. Electric assist means that a small battery-operated electric-propulsion system is provided to assist the driver's leg muscle effort. Most electric-assist propulsion motors are of the in-wheel design in the rear wheel, such as geared hub
802:
Much of the cycle-related infrastructure design is based on the typical configuration of an upright bicycle. For example, multi-modal transportation such as bike/train/bike routes often use bicycle racks in the train, and the dimensions of racks and also the train ingress/egress assume a conventional

Some velomobile fairings are mainly for weather protection. However, if the velomobile fairing is substantially streamlined, then improved aerodynamics means the speeds on flats and down hills may be substantially higher than its unfaired counterpart, and often enough faster to make up for the slower
613:
As of 2017, there are several commercial makers of velomobiles. At the same time, there are still many "one-off" makers. Individual designs (both one-off and production) emphasize specific features. For example, some emphasize aerodynamics and light weight to improve average speed, even if cost, ease
593:
As of 2017, most velomobiles are tricycles with two front wheels. A tricycle has the advantage over a bicycle that it does not fall over when stopped. In addition, when a cross-wind hits a fairing, it makes a big force; faired tricycles are less likely to get blown over than faired bicycles. Although

Positive features, such as easily adjustable and comfortable seats, independent pedalling for both passenger and driver, adequate cargo space and relatively good weather protection, could not overcome the negative features, such as a complex, heavy and badly spaced three-speed gear box, ineffective 827:
While an electric-assist unit does add extra weight to the velomobile, it is somewhat offset by the flexibility it also provides, especially during hill climbs and stop-and-go traffic. Due to vastly better aerodynamics of velomobiles the range of a similar electric assist unit and similar battery in

Two-wheel "streamliner" configurations can have much less aerodynamic drag: wheels are hard to make aerodynamic; each wheel entry/exit to the fairing adds drag; and velomobiles with two front wheels are necessarily wider or longer than the rider, while two-wheel streamliners can be barely wider than

than an equivalent unfaired cycle. In contrast an unfaired cycle cannot have fairing interference, and so even with the same wheel and rider configuration can steer a much tighter circle. Steering only the rear wheel(s) would avoid fairing interference, but it is hard to build a stable vehicle using
522:
There are many ways to build a velomobile. One modern design is "body-on-frame", in which a velomobile is made from a not-faired cycle plus a body. A standard cycle may be used, but often a custom cycle is used with special fittings to mount the body; the use of special fittings tends to improve fit

The fairing on a velomobile sometimes makes it more subject to cross-winds than a similar unfaired cycle. The effect of cross-winds is complicated because the force of the wind can act as a steering force, as-if the rider had tried to steer the cycle. "Wind steer" can be a safety issue and may also

Though fast in their own right, velomobiles are considered much more suitable for the street than two-wheeled streamliners. Using three or more wheels can have advantages for everyday use, including the ability to stop and start unaided, better stability, cross-wind handling, etc., though there are
790:
Velomobiles are often built using some standard bicycle parts, but also many parts specific to velomobiles or even specific to a particular make or model. In addition, the bodywork is large and may be around half the weight of a velomobile. Thus, to reduce weight, the body is often made of lighter
786:
Velomobiles are significantly bulkier than conventional cycles. Further, the bodywork typically cannot be disassembled much, whereas conventional cycles often can be disassembled to fit in a box or bag of dimensions similar to the frame. In turn, this makes velomobiles more difficult to transport.
744:
The steered wheels on a velomobile will hit the fairing if steered sharply enough. Making the fairing wider can give space to steer the wheels more sharply, but has down-sides for aerodynamics and width. Although sharp steering is not needed at speed, many aerodynamic velomobiles have a much worse

A velomobile's fairing shields the drivetrain from weather, as well as the rider. Drivetrain maintenance is often reduced compared to other cycles, especially unfaired bicycles, where the front wheel kicks up grit-containing dust, mud, and dirty water that lands directly on the chain and increases

to use a solid disk rear wheel for best aerodynamics, and a spoked front wheel that has worse aerodynamics than a disk, but is less likely to steer the bicycle in a cross-wind. Velomobile fairings have analogous concerns, leading to trade-offs in fairing design. For example, a longer "tail" on the

All current (2017) velomobiles are produced in low volume, with "big" makers producing one or a few velomobiles per week. Velomobiles use some standard bicycle parts, but also many parts specific to velomobiles, and thus made in low volume. The use of "more parts" (e.g., 3 wheels instead of 2) and

As with other cycles, a velomobile may use suspension. Suspension tends to improve rider comfort, and can also improve speed—it takes energy to "bounce" the velomobile and rider, so a suspension can reduce the energy lost to bouncing. However, suspension adds cost, weight, and maintenance. Common

or "FRP", plus sub-frames of welded aluminum tubes. FRP can be used to produce a wide range of shapes, and thus can improve aerodynamics over approaches such as "birdcage" and aluminum-sheet monocoque. FRP can also use fibers with high strength-to-weight ratio that in velomobiles can save several
782:
Velomobiles for cargo use often have heavy frames to carry load, plus the weight of the cargo itself. In turn, the weight of the fairing may be relatively less important. Also, bulky loads often have poor aerodynamics, and so the quality of aerodynamics of the fairing is less important. This may

Velomobile bodies are typically light enough that the center of mass is similar to the center of mass on an unfaired recumbent cycle. This makes cornering stability similar to similar unfaired cycles. However, minimizing velomobile width also contributes to reduced frontal area and thus drag; so

three wheels have practical advantages, they also have more aerodynamic drag than two wheels, so land speed record cycles are often bicycles. Although four wheels were used as far back as the Velocar, they are not today common. As of 2017, there is at least one 4-wheel production model, the

598:. Four wheels tends to further hurt aerodynamics and weight compared to three; but for a given width, four wheels is much more laterally stable than three wheels. Also, four wheels can be placed in a way that increases luggage capacity a lot compared to three-wheel designs. 339:
arguments made that the multiple track machines (three or more wheels) have aerodynamic disadvantages due to the drag of the extra wheels and the surface contact points. In practice though, velomobiles continue to be close to their two-wheel cousins in performance.

Some other early velomobiles use a fabric body or "skin" sewn to fit loosely on closely spaced wires or tubes, then painted or "doped" with a liquid that dries and shrinks the fabric to a tight fit on the wire/tube supports. The approach was used widely on early
