The old 1963 song, “The Bird’s the Word,” should be replaced by a new one called, “The Battery’s the Word.” No, wait, that’s just dumb. Anyway, the fact remains, all eyes in mass transit are on electric vehicles. So far, however, few bikes have managed large production numbers, but among those Zero has perhaps done best. Yeah, there’s no engine, but this “motorcycle” preserves the all-important rider interface via agreeable handlebar, seat, and peg positions, making it a joy to ride instead of forcing the rider to adapt to the bike. Do we think the Zero SR/F is beautiful? Not especially! But per the German term “Bauhaus,” which generally embraces minimalism and “form follows function” modernism, it’s a stunner.
