In cycling, cadence is a measure of rotational speed of the crank, expressed in units of revolutions per minute (r/min or rpm). In other words, it is the pedalling rate at which a cyclist is turning the pedals. Cadence is directly proportional to wheel speed, but is a distinct measurement and changes
To ride closely behind another rider to make maximum use of their slipstream, reducing wind resistance and effort required to ride at the same speed.

Reducing the weight of the bike + rider by 1 kg would increase speed by 0.01 m/s at 9 m/s on the flat (5 seconds in a 32 km/h (20 mph), 40-kilometre (25 mile) time trial). The same reduction on a 7% grade would be worth 0.04 m/s (90 kg bike + rider) to 0.07 m/s (65 kg bike + rider).
European city bike Children riding a bike in Ghana. Cycling, [1] also known as bicycling [2] or biking, [3] is the activity of riding a bicycle or other type of cycle. It encompasses the use of human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, which types of cycling environment or cycling infrastructure is safest for cyclists.
Vehicular cyclists do not avoid riding in bicycle lanes, rather they decide whether to ride in the space demarcated as a bike lane based on their own judgement about safety. [12] They are also advised to stay outside of the door zone ; when passing motor vehicles that are parked parallel to the road, no closer than the largest estimated width ...
Here are more tips from the KDOT to bike as safely as possible: Wear a helmet approved by an organization such as the American National Standards Institute, American Society for Testing and ...
On an upright bicycle, also called a safety bicycle, the rider sits astride the saddle. On a recumbent bicycle the rider reclines or lies supine. Recumbent bicycles (also 'bents) are designed to maximise comfort and minimise wind resistance, because the rider in a supine or semi-supine position. Whereas most of the other types of bicycle in ...
