Now to round off the bunch, the Zero DS is a street legal motorcycle that offers a super comfortable ride on the street and can easily venture out into some mild trails. In stock form, this silent commuter feels more like a street bike than an off-roader, and if you want a street legal dirt bike then you probably don't want the DS because you can get the X and MX models with street legal trim and will be able to tackle more difficult terrain. With that said this bike is perfect for commuting daily from distances as short as a couple of miles up to about 40 or 50 miles. Anything longer than that would be pushing your luck and you may wind up pushing your bike to the nearest electric outlet. If you have some sweet shortcuts that could cut your travel in half or shorten your ride by any distance, this bike can get you there but you may want to put a more aggressive knobby pattern on to make the trails more fun and to gain any extra traction. For 2011, the Zero DS received a new quick charge option that reduces battery charge time by about 50%. Also, new beefier brakes, dual sport tuned suspension, a quiet belt drive system that defines silence and a 12.5% increased battery capacity to get you around the bend. At $10,495 you may be drawn away to something a little less expensive, but think about how you can cancel gas stations from your regular routine and charge up to a full battery for about $0.48! Now that makes gas prices look silly.Zero's line of off-road dirt bikes is still young and hasn't had much time to mature yet but judging by the improvements that were made from last years models, I'd say this company is putting in many hours at the drawing board and at the track to find the right formula to a successful line of race bikes. Being a fairly new company, Zero has a great team of Leaders, engineers and people with lots of experience in the industry that have the ability to take electric powered motorcycling to the next level. These futuristic electric bikes may seem overpriced, but with gas prices where they are and as rapidly as new technology seems to be surfacing, I wouldn't be surprised to see more and more people going green and converting to a 100% electric set up to satisfy their motorcycle sweet tooth.
