Well, Zero has the 2018s on their website and I'm looking hard at one of these bikes for the reasons stated above. And, I'm a big fan of electric technology. I've got a Stromer ST1 electric bike but am a motorcycle guy and this thing gets me excited just looking at it. We're into winter here in Colorado (snow in the forecast) but I'm not sure I could wait until spring. Besides, the colder weather kinda forces you into shorter rides. Fine with me. Not sure when the 2018s will arrive at my local dealer and I have not test ridden one yet, mostly because I KNOW that a test ride will seal the deal. They have a 2017 Zero DS13.0 which, I assume, is a bit larger battery.
