A bicycle, pedal cycle or bike is a human-powered two-wheeled vehicle with one or more wheels mounted on a frame. It is a popular form of transportation and exercise in many countries around the world, particularly those with low car use.
Pedal-powered vehicles are considered to be the best means of transportation for people who live in areas with limited car use. Bicycles can be used for commuting, recreation and fitness, shopping and tourism.
Common components on a bicycle include a seat, pedals, wheels, brakes, and gear shifter. The pedals are pushed with the feet to move a chain that turns the back wheel, which steers the bicycle. Most bikes also have a front wheel that is driven by a gear shifter.
The basic design of a bicycle has not changed much since its invention, but the bicycle industry is constantly experimenting with new designs and technology. The most significant innovation of the past 100 years was the introduction of multiple-speed gearing, which allowed cyclists to ride faster than ever before.
Modern bikes can be manufactured from a wide range of materials, including aluminum alloys, steel, titanium, and carbon fiber. They are typically lightweight and have good strength.
Some of the lighter, cheaper models are made from wood, bamboo or other natural materials. Some are even made from recycled materials.
The most common material for the frame is steel, with aluminum tubing becoming more prevalent as welding techniques improve and prices decrease. However, some more expensive bikes are now being made from carbon fibre.
Cycling is a healthy way to get around and it’s a great way to exercise without putting too much stress on your body. It’s also a fantastic way to reduce your carbon footprint.
When you’re riding your bike, it’s important to follow traffic rules, signs and signals. This includes obeying stop signs and red lights, and never overtaking a pedestrian or another bicycle in a crosswalk. It’s also a good idea to give other road users audible notice when you intend to pass them.
Safety is the number one priority when cycling, so always ride safe and keep your head up. A collision can be devastating and could cause serious injury or death.
It’s also very important to be aware of the weather conditions when you’re cycling outdoors, and avoid riding in extreme heat or cold. This can make it harder to control the speed of your bike and reduce the amount of oxygen your body receives.
In addition, you should always wear a helmet while riding your bike, especially when it’s raining or snowing. Riding with a helmet can protect you from injuries such as concussions or traumatic brain injury.
In addition to being a great way to get around, biking is also a fun and enjoyable activity. It’s easy to learn how to ride a bike, and it’s also an excellent workout for your whole body. Besides improving your cardiovascular system, cycling can also help you improve your balance and coordination. It’s also a great choice for those with joint issues or stiffness in the lower body.
