History of Electric Bicycle Motors
For more than a century, bicycles have offered fun and inexpensive transportation. Motor-in-hub engineering enabled the development of electric bicycles. Electric bicycles are designed with an attached electric motor that assists in--or even takes the place of--peddling.

Beginnings
-
The origin of electric bike engineering can be credited largely to three men: Adam Wellington, Albert Parcelle and Edward Parkhurst. The original patent for an in-hub motor was filed in 1884 by Wellington. In 1890, the remaining two men made contributions to the field--the first hub motor was built by Parcelle, and Parkhurst invented the first, low-rpm, high-torque electric hub motor.
Motors

Among the early designs, both internal combustion and electric engines were popular. But as technology advanced and power storage capabilities improved, lighter batteries were designed and the electric motor began to grow in popularity.

Green Transport

Electric bikes continue to grow in popularity, especially in Asia and Europe. By 1996, there were 370,000 motorized bikes in Shanghai. In Europe, the continuing popularity of these hybrid vehicles is based on eco-concerns, aging citizens, matters of economy and traffic congestion.
