For some, the notion of an electric motorcycle goes against what makes riding so much fun: the visceral roar and rumble of the engine.
But political forces are massing against the petrol-driven motorbike, with Germany due to ban all internal combustion engine vehicles by 2030 and the UK under pressure to bring in its own 2040 ban earlier.
So, is it time to embrace the electric motorbike? If so, this year you'll find plenty to get excited about.
Here are five of the most exciting electric motorbikes of 2019 so far...
The Vespa brand is synonymous with classic two-stroke engines, but the firm unveiled its first electric bike in 2016, ushering in a new age for the beloved Italian marque. Boasting a range of 62 miles, the Vespa Elettrica can be ordered on the firm's website.
The US-built Zero SR/F was launched in Amsterdam two months ago, impressing reviewers with its styling and superior build quality. However, many have noted with dismay that the battery depletes rather quickly when the bike is pushed. It is, however, a lot of fun to ride, according to motorcycle reviewers.
The Livewire is due to arrive in autumn, so Harley fans who've moved across to "the dark side" will have to be patient a little while longer. The machine boasts Showa shocks, Bluetooth connectivity and a TFT dashboard. Prices will start at £28,995.
The Super Soco TC-Max aims to replicate the performance of a four-stroke 125, while being cheaper to run. It's also economical to buy, starting at only £3,999. It has a top speed of 60mph and a range of 60 miles.
At the other end of the spectrum is the very top-spec Curtiss Zeus which aims "to deliver a range of 280 miles, 145ft-lb of torque and a 0-60mph time of 2.1 seconds, all with a 140Kw motor," according to Paul Ogilvie, Advanced Power Train Division Leader. This kind of performance puts it in the same league as British motorcycle start-up, Arc, whose Vector machine will cost around £90,000.
