In some countries, bicycles must have functioning front and rear lights when ridden after dark. [135] [136] The Wrights' bicycle shop". 2007. Archived from the original on 25 January 2007 . Retrieved 5 February 2007.A human traveling on a bicycle at low to medium speeds of around 16–24km/h (10–15mph) uses only the power required to walk. Air drag, which is proportional to the square of speed, requires dramatically higher power outputs as speeds increase. If the rider is sitting upright, the rider's body creates about 75% of the total drag of the bicycle/rider combination. Drag can be reduced by seating the rider in a more aerodynamically streamlined position. Drag can also be reduced by covering the bicycle with an aerodynamic fairing. The fastest recorded unpaced speed on a flat surface is 144.18km/h (89.59mph). [55]

About

The combined center of mass of a bicycle and its rider must lean into a turn to successfully navigate it. This lean is induced by a method known as countersteering, which can be performed by the rider turning the handlebars directly with the hands [49] or indirectly by leaning the bicycle.
