My regular long-term bike is the Indian Scout, a powerful and smooth (by V-twin standards) cruiser. But the Zero S introduced me to a whole new level of smooth. The total absence of any engine vibration, combined with the instant acceleration of an electric motor, took me like a whirring rush up to whatever speed that I wanted to level off at. Once on the freeway, I had a nice open stretch where I kept the right grip twisted all the way until I felt the bike hold at a steady 93 mph. Within that short time I noticed that my power meter indicated that I'd consumed about 10 percent of a full 100-percent charge. So I backed off to a legal pace and mixed in with traffic.
