bike

A bicycle, often called a bike or cycle, is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
Bicycles were introduced in the 19th century in Europe and as of 2003, more than 1 billion have been produced worldwide, twice as many as the number of automobiles that have been produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, and bicycle racing.
The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. But many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for many types of cycling.
The bicycle's invention has had an enormous effect on society, both in terms of culture and of advancing modern industrial methods. Several components that eventually played a key role in the development of the automobile were initially invented for use in the bicycle, including ball bearings, pneumatic tires, chain-driven sprockets, and tension-spoked wheels.

    Bike carriers and height restrictions

    This is going to be a bit of a silly question, but I'm well known for sometimes overlooking the obvious. Due to the logistics of the wife and I commuting to work and taking the baby to nursery, it would often be handy to have a bike rack on the car; the reason is that some weeks I can only do...

    We are looking to take four kids bikes away with us for the summer this year - seeing what the options are for carrying them with the full Caravelle. The obvious choice seems to be adding a tow bar and tow-bar mounted bike carrier. If I put tow bar into google, places like Halfords and...

    Bike Hybrid Frame Size

    Anybody have a bike that's 5' 10" if so what size of frame have you got and recommend? I seem more or less on the border. When buying trousers I get 32 inside leg but I'm 33 to floor. So more or less sticks me in the middle of two sizes. My span is greater than my height so looks like its...

    Bike rack recommendation

    Hi all, I'm looking for a roof mounted bike rack to fit a Mazda 5 (has roof rails). Can anyone recommend a bike rack for two adult bikes, or recommend a decent company to look at? I know the Thule systems are good but they are pricey and this won't get used a huge amount. Thanks! :)
