Fitness Bicycles have most of the advantages of regular road bikes–lightweight frames and relatively narrow tires for efficiency on pavement–with a flat or upright handlebar. These bikes are designed for people who want a light, high-performance bike, but don’t like the drop-handlebar riding position of a regular road bike. These bicycles are sometimes called flat-bar road bikesor performance hybrid bikes. Most of them can accept somewhat wider tires, to make them suitable for use on unpaved trails. They usually have the ability to mount cargo racks and fenders, which make them good commuter bikes.

A dérailleur system normally has two dérailleurs, or mechs, one at the front to select the chainring and another at the back to select the sprocket. Most bikes have two or three chainrings, and from 5 to 11 sprockets on the back, with the number of theoretical gears calculated by multiplying front by back. In reality, many gears overlap or require the schwinn spin bike chain to run diagonally, so the number of usable gears is fewer. The bicycle has undergone continual adaptation and improvement since its inception. These innovations have continued with the advent of modern materials and computer-aided design, allowing for a proliferation of specialized bicycle types, improved bicycle safety, and riding comfort.

Experiments done in Africa and Sri Lanka on hundreds of households have shown that a bicycle can increase the income of a poor family by as much as 35%. Transport, if analyzed for the cost–benefit analysis for rural poverty alleviation, has given one of the best returns in this regard. For example, road investments in India were a staggering 3–10 times more effective than almost all other investments and subsidies in rural economy in the decade of the 1990s. What a road does at a macro level to increase transport, the bicycle supports at the micro level. The bicycle, in that sense, can be one of the best means to eradicate poverty in poor nations.
