As a daily rider, the Zero S is excellent. The only significant complaints pertained to the hard seat and a lack of off-the-line acceleration. On the plus side, I love how simple this single-speed, direct-drive bike is to operate and that I get to delete gas stops from my weekly routine. If you’re after ease of use, it doesn’t get much better than the Zero: Plug it in when the battery gets low and keep air in the tires, but otherwise just ride it and enjoy a smooth and green means of getting around. With no fluids (besides brake fluid), filters, or spark plugs to change and a low-maintenance belt final drive, the Zero is about as easy to take care of as a houseplant.
