What do bicycles look like?

Bicycles are vehicles with two wheels, one behind the other, and a frame that connects them. They are powered by the rider's legs, which turn the pedals that drive the wheels. Bicycles have handlebars that the rider holds onto, a seat for the rider to sit on, and brakes to slow down or stop. Some bicycles also have gears that allow the rider to change how fast the bike goes.

There are many different types of bicycles, including road bikes, mountain bikes, hybrid bikes, and city bikes. Road bikes are designed for speed and efficiency, while mountain bikes are designed for rough terrain. Hybrid bikes are a combination of road and mountain bikes, and city bikes are designed for commuting and everyday use.

Bicycles can be used for recreation, transportation, and racing. They are a popular form of exercise, and they are also a convenient and environmentally friendly way to get around.
