About Electric Bicycle
Electric Bicycle - Motorized bicycle, photo wallpapers: A motorized bicycle is a bicycle with an attached motor used to assist with pedaling. Generally considered as a vehicle, sometimes as a motor vehicle or a class of hybrid vehicle, motorized bicycles are usually powered by electric motors or small internal combustion engines. Some can be propelled by the motor alone if the rider chooses not to pedal, while in others the motor will only run if the the rider pedals. Different regulatory authorities use a variety of names and classifications. Early motorized bicycles were powered by internal combustion (IC) engines. As electric motors have become lighter and battery storage density higher, the electric motor has recently seen an increase in popularity.
Motorized bicycles are distinguished from motorcycles by being capable of being powered by pedals alone if required. Many motorized bicycles are based on standard bicycle frame designs and technologies, although the modifications to the design to support motorisation may be extensive. In countries where there is a strong bicycle culture (notably in Asia), the motorised bicycle is particularly popular.
The origins of the motorized bicycle can be traced back to the latter part of the 19th Century when experimenters began attaching steam engines to stock tricycles and quadracycles. This moved into attempts to fit the newly-invented internal combusiton engine to the bicycle form. Development diverged into two distinct streams: motorcycles, which are powered solely by their engines, and motorized bicycles as defined above. The closeness of the two forms in early years is demonstrated by Félix Millet's machines of 1892/93 and on. These had both pedals and an ingenious fixed crankshaft rotary engine built into the back wheel. Within a few years motorized bicycles and motorcycles were recognisably divergent, with for example the early Harley-Davidson motorcycles of 1901 being longer, heavier and with a markedly dif...
