The bicycle is a tremendously efficient means of transportation. In fact cycling is more efficient than any other method of travel! The one billion bicycles in the world are a testament to its effectiveness. The engine for this efficient mode of transport is the human body. Because bodies are fueled by food, diet plays an important role in how the body performs. Different muscle groups and types provide the power. Genetic inheritance, intensive training, and a competitive drive help top athletes push the boundaries of endurance and speed on the bicycle.

These have lighter, smoother tyres and a slightly
modified mountain bike frame, with a more upright riding
position specially adapted for urban cycling. They
are often sold with mudguards and other utility
fittings as standard. Hybrids can cope with a wide
range of terrain and are a good option for everyday
trips. They are less suitable for sports or specialist
cycling.
Road or racing bikes
Drop handlebars, light wheels and thin slick tyres
make these the most efficient and fastest bikes
for the road. However, they are more prone to
punctures and do not cope well with poor
surfacing. You may also find the riding position
less comfortable than a hybrid for everyday
journeys.
Mountain bikes
Originally designed for off-road cycling, the wide
range of gears, suspension and good
manoeuvrability have made these equally popular
with urban riders. However, the knobbly tyres
make pedalling harder, so it’s advisable to fit city
tyres if you rarely go off-road. The riding
position may not be as comfortable as a hybrid
for everyday journeys and items such as
mudguards and carrier racks will usually need to
be fitted separately.
Folding bikes
These are specifically aimed at those who want to
combine cycling with other modes of transport.
They are ideal for bus or train commuters who
want to cycle to and from the station. However,
their small wheels and often limited range of gears
make them only really suitable for relatively short
urban journeys.
