Throughout the history of the bicycle, numerous attempts have been made to create a powered bike. The
motorcycle evolved out of attempts to attach internal combustion engines to bicycle frames. However
the amount of power a motorcycle can generate is far beyond a bicycle, making them sometimes inappropriate
for use in neighborhoods or crowded cities. In addition, internal combustion engines pollute and can
be wasteful.
Some designers have found a middle ground between the two. Between motorcycles and mopeds on one hand,
and standard human-powered bicycles on the other, are motorized bicycles. Unlike motorcycles, where
the sole source of energy is the engine, the motor on a motorized bike is smaller and intended as supplemental
energy. Anyone who has pedaled up a steep hill knows how difficult it can be, especially for people
with limited lung capacity. The help of a motor can make these hills climbable.
In the United States, motorized bicycles are required to have a top speed less than 20mph and an engine
under 50cc displacement or 750 watts. Modern motorized bicycles most often use electric motors because
of their efficiency and lesser environmental impact. Often the motor only kicks in to provide supplemental
power when the rider is pedaling. In other designs, the pedals drive a generator that recharges the
bicycle's batteries. Some designs use a combination of both features.
In parts of China, a country famous for its bicycle use, electric bicycles constitute up to 20% of the
vehicles on the road. For people who live in very hilly areas, or who have conditions that make cycling
more difficult, powered bicycles can mean increased mobility.
