The firm said the bike will go on sale next year - although still hasn't said how much it will cost, or long it can go on a single charge.

Prototype bikes could hit 92 mph, and had a range of 60 miles - although both of these figures are expected to be improved in the final version.

Harley has also addressed the problem of silent electric bikes - although the Livewire won't have quite the roar of the firm's gas-guzzling bikes.

'The gear set between the motor and the drive belt has been designed to produce a tone that increases in pitch and volume with speed, producing an exciting aural response to speed and acceleration,' the firm said.

The bike will be controlled through a touchscreen, and have  seven different riding modes.

Music and GPS are controlled by a state-of-the-art touchscreen infotainment system that’s Bluetooth enabled.  

The bike is key to a new business model for the Milwaukee-based company, which is looking to engage with a wider range of customers as demand dwindles for its iconic petrol-hungry bikes.

Harley-Davidson is facing shrinking sales in its home market of the United States, and is hoping to broaden its appeal to new customers in a bid to invigorate sales.

'Alongside our existing loyal riders, we will lead the next revolution of two-wheeled freedom to inspire future riders who have yet to even think about the thrill of riding,' Harley-Davidson CEO Matt Levatich said in a statement. 

Famed for its roaring engines, Harley-Davidson's LiveWire will have no clutch or gears.

Users will be able to power  at home via a Level 1 charger, or do so more quickly with Level 2 or 3 models or DC fast chargers. All Harley dealers that carry the bike will have Level 2 DC fast chargers on site

This decision was made as part of the US company's goal to make motorcycle-riding accessible to a wider range of people.

The company said LiveWire will be followed by more 'twist and go' electric two-wheelers over the next few years, with lighter and smaller models already planned.
