An ordinary bicycle is also commonly referred to as a standard bicycle, traditional bicycle, or conventional bicycle. Additionally, it may be called a road bike, commuter bike, or recreational bike, depending on its intended use. Other synonyms for an ordinary bicycle include pushbike, pedal bike, or simply, bike. In contrast, electric bikes, folding bikes, and mountain bikes are all specialized variations of the ordinary bike. Despite being referred to as "ordinary," standard bicycles remain a popular mode of transportation and recreation worldwide. They are affordable, environmentally friendly, and provide a great form of exercise and exploration for riders.
