This means that over 200,000 electric bicycles were sold in Israel in a period of three years. The electric assistance to the rider reduces the physical efforts required for riding an e-bicycle.

Empirical studies showed of which 36.8 million (91.9%) were sold in China that electric bicycle riders usually rode faster than and over 2.3 million (5.8%) in Europe (Fishman and conventional bicycle riders, yet, the speed differences Cherry, 2016).
