Bicycle

A bicycle is a bipedal person-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other.
Since their creation, bicycles have been and are employed for many uses. In a utilitarian way, bicycles are used for transportation, bicycle commuting, and utility cycling. It can be used as a 'work horse', used by mail carriers, paramedics, police, messengers, and general delivery services. Military uses of bicycles include communications, reconnaissance, troop movement, supply of provisions, and patrol as part of a bicycle infantry.
The bicycle is also used for recreational purposes, such as bicycle touring, mountain biking, physical fitness, and play. Bicycle competition includes racing, BMX racing, track racing, time trials, and major multi-stage professional events.


While bicycles do take some resources to build and maintain (particularly various metals for frames and rubber for tyres), these are far lower than modern automobiles. Person-powered bicycles also do not require using non-renewable petroleum as a power source, do not emit any air pollution during use, and require far less parking space and heavy road infrastructure per person than is required for automobiles. They are also far less likely to kill and/or seriously injure cyclists or other street users such as pedestrians than heavy, motorized transport.

Power Generation

They are generally person-powered by pedals those electrical bikes use alternative methods like batteries.

Additional & auxiliary systems

Bike Trailer: A bicycle trailer is a motorless wheeled frame with a hitch system for transporting cargo by bicycle. It can greatly increase a bike's cargo capacity, allowing point-to-point haulage of objects up to 3 cubic metres (3000 liters, or 4 cubic yards) in volume that weigh as much as 500 kg. However, very heavily loaded trailers may pose a danger to the cyclist and others, and the voluntary European standard EN 15918 therefore suggests a maximum load of 60 kg on trailers without brakes.

Bicycles are not expensive. Affordability is related to the availability of spare parts and repair services, which are sometime lacking in rural areas.
