The most comprehensive book yet about the pivotal transition from gas-powered cars and motorcycles to electric ones, The Current: New Wheels for the Post-Petrol Age is 208 pages of silent, speedy machinery. It showcases the incredibly bright future for the category, whether it's electric motorcycles, bicycles, cars, SUVs, trucks, or even hybrid drives, from both pioneering new brands and legacy stalwarts. More than just pictures to ogle at, the book breaks down many of the concepts — some need explaining — and spotlights some of their founders. If nothing else, it provides excellent contrast between electric vehicles now and the seemingly endless directions they could go.
