The LiveWire™ motorcycle features a high voltage battery that produces incredible acceleration. Harley-Davidson's LiveWire, the company's first electric design, seemed like a one-off prototype when it appeared in 2014. But the bike is very real. The bike will get power from a permanent magnet electric motor, specifically designed to "produce a tone that increases in pitch and volume with speed." The idea, I gather, is to have some audio indication of the power the bike is producing, which will make for a more-thrilling ride while also attracting people who might be skeptical that an electric bike can replicate what they like about gas-powered Harleys.
