Cykels

Cykels is a term used to refer to bicycles, a class of two-wheeled, human-powered vehicles designed for forward motion by pedaling. They are widely used for everyday transport, sport, and recreation, offering a flexible and energy-efficient means of travel.

The modern bicycle emerged in the 19th century in Europe, evolving from early illusionary designs into a safer, mechanically-driven machine. Key developments included the chain drive, the use of a frame with two wheels of equal size, and the introduction of pneumatic tires, which improved comfort and efficiency. Since then, bicycles have diversified into numerous styles to suit different terrains and purposes.

Typical bicycles consist of a frame, two wheels, a drivetrain that transfers pedaling power to the rear wheel, brakes for stopping, steering, and a saddle. Common categories include road bikes optimized for speed on pavement, mountain bikes designed for rough terrain, and hybrid or city bikes for everyday use. Variations such as cargo bikes, folding bikes, and electric bicycles expand practical applications. Components can be customized for performance, comfort, or durability, and many bikes use standardized parts to enable easy repairs and upgrades.

Bicycles offer environmental and public health benefits by reducing emissions, traffic congestion, and sedentary time. They require relatively low maintenance and can be integrated into multimodal transport systems with public spaces and bike infrastructure. Safety considerations include wearing protective gear, using lights and reflective materials, and adhering to local traffic rules.
