Here's a bike that runs entirely on electricity. Zero Motorcycles of Santa Cruz, CA has introduced the Zero DS, a fully electric, dual-sport motorcycle built for both the city street and the dirt trail. The Zero DS was designed from the ground up as an electric vehicle. Each component on the bike — such as aircraft-grade aluminum with lightweight strength — was designed to minimize weight and maximize energy density.
