A lot of motorcyclist love the distinctive growl of a Harley-Davidson — and often add extra-loud exhaust pipes to amp up the sound. But the Harley-Davidson has just rolled out a prototype bike that makes more of a whisper than a rumble. It’s a sweet-looking model called LiveWire, and it’s powered by batteries. The legendary motorcycle maker will be taking its prototype electric motorcycle to 30-some cities in the coming months. Sometime after that, the company will decide whether to put LiveWire on the market.

Motorcycles powered by rechargeable batteries have been buzzing around for years, capturing a small part of the U.S. motorcycle market. Harley, meanwhile, has always been known for its gasoline-powered bikes.
