A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10] 12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe without special protective measures.

A typical unit requires eight hours to charge the battery, which provides the range of 25 to 30 miles (40 to 48 km), [16] at the speed of around 20 km/h (12 mph). [17] In the 2010s electric bicycles attracted considerable traction in Europe [18] led by government policies and environmental awareness encouraging sustainable technologies. Some ...
