The vast majority of Asia's motorbikes currently run on petrol, but transport experts say that a big switch to electric versions is now gathering pace.

"We see immense scope for growth [in sales of electric motorbikes], especially in Asia, for the following reasons," says Arushi Kotecha, an automotive analyst at global research group Economist Intelligence Unit.

"The first, is personal disposable incomes, especially outside China, in markets like India and southeast Asia, still remain low on average, which makes cars unaffordable.

"And, especially at a time like this, when food and fuel inflation is so high. That would add to the direct cost of owning a petrol vehicle. Which is why we think that the switch to electric [motorbikes] will be much faster."

While the big Japanese motorbike manufacturers like Yamaha and Honda are now making electric models, the Asian market has been led by newer companies.

Taiwan's Gogoro is one such firm. In addition to a range of electric motorbikes, it has come up with a solution to the problem of a rider having to stand around while their bikes charge.

Instead of charging points, Gogoro's users in Taiwan simply need to drive to one of more than 2,200 battery stations, and swap their batteries for free. The outdoor stations run 24-hours a day, and are said to be able to withstand the typhoons and searing heat of Taiwanese summers.
