Electric bikes are set to see a 54.7% increase in sales over the next nine years - growing from $15.7 billion in revenue to $24.3 billion by 2025 - according to research from consultancy firm Navigant. 

Examining the global market for Electrically Power Assisted Cycles (EPACs), Navigant published their Electric bicycles study which highlighted the shift away from sealed lead acid batteries towards lighter, more efficient, and longer living Lithium-ion batteries.

The expected growth in the e-bike market also takes into account the anticipated decline in the Chinese e-bike market due to a combination of market saturation and recent bans on e-bikes in major cities.

Talking to BikeBiz.com Navigant's research analyst Ryan Cirtron pointed towards the growing difficulty of urban transportation as an explanation for the rise of the e-bike.

He said: "Rising levels of population density and traffic congestion are driving interest in different modes of transportation."

"E-bikes are uniquely positioned to be a primary benefactor of this trend since they are low in cost relative to cars, do not require licenses to operate, and can take advantage of existing bicycling infrastructure."

The expected loss in China will impact the global growth of the e-bike market, things are looking brighter in Europe.

The Confederation of the European Bicycle Industry released figures recently that showed huge growth in the e-bike industry in 2015, and expectations of continued growth accross Europe.
