Road cycling is the most widespread form ofcycling in which cyclists ride on paved roadways.[1] It includesrecreational,racing,commuting, andutility cycling. As users of the road, road cyclists are generally expected to obey the samelaws as motorists, however there are certain exceptions.[2] While there are many types ofbicycles that are used on the roads such asBMX,recumbents,racing,touring andutility bicycles, dedicatedroad bicycles have specific characteristics that make them ideal for the sport. Road bicycles generally have thinner tires, lighter frames with no suspension, and a set of drop handle bars to allow riders to get in a moreaerodynamic position while cycling at higher speeds.[3] On a flat road, an intermediate cyclist can average about 18 to 20 mph (29 to 32 km/h), while a professional rider can average up to 25 mph (40 km/h).[4] At higher speeds,wind resistance becomes an important factor; aerodynamic road bikes have been developed over the years to ensure that as much as possible of the rider's energy is spent propelling the bike forward.[4]
In 1817,Karl von Drais created the first bicycle which used heavysteel andwood, but since then, the road bicycle industry has adoptedaluminum,carbon fiber, andtitanium as the main materials for production.[5] The first steel bicycles weighed as much as 80 pounds,[5] whereas the lightest carbon fiber road bikes now can weigh as little as thirteen pounds.[6]
On May 31, 1868, cycling officially became a sport with the first race occurring at Saint-Cloud Park inFrance.[7] While this first race was not considered a road race, road cycling races began to pop up throughoutEurope in the 1870s.[7] Road cycling as a form ofrecreational activity as well as a way tocommute began to gain traction shortly after these first road races.[7] Since its origins, millions of people have adopted road cycling for either recreation or commuting.
In 2020, it was estimated that about 44.5 million people worldwide participate in road cycling, which is an increase of about five million people since 2019. Demand for road bicycles as well as other types of bicycles continued to increase throughout 2021.
Sharing the roadways with other motorists is an unavoidable aspect of road cycling, so road cyclists are generally expected to follow the samelaws as their motorist counterparts. That being said, road cyclists also have the same fundamentalrights as motorists.[2] In theU.S., laws for cyclists vary by state, so it is important to keep up to date on your state's road cycling laws.[8]You can find a breakdown of all cycling laws by state here.
While laws on wearinghelmets vary by jurisdiction in theUnited States,Australia andNew Zealand, helmets significantly reduce the risk of serious injury and death in the event of an accident.[9]

In 2019, 846 cyclists were killed in road related accidents in the United States.[2] Most fatal bike crashes were caused between 6 P.M. and 9 P.M. and about 78% of fatal crashes in 2019 were inurban areas.[2]
