Zero Motorcycles Forum | 2013+ / Re: 2015 Zero S Stutter After Startup
« on: January 10, 2019, 11:28:09 AM »
The bike made it home tonight, and I decided to take some videos to share. In the process of taking the videos I think the bike took its last breath as it will no longer charge and is incredibly hard to get rolling. Error codes 25, 48, and 49 pop up constantly and I can't even get the bike to turn on to grab the logs. I'm so sad about it and it is my only mode of transportation so I'm going to have to start taking Uber to work until it's fixed I suppose :(.

Here are the videos:



I hope Zero will help me out, I really love this bike and have been an ambassador for them since my purchase.

Thanks, I'll be sure to check those out and let you know. I don't believe it's a battery temperature issue since the bike stays in the garage and our lowest low this year has been ~33 which still keeps over 50 degrees in the garage. I did not cycle the cutoff switch, I have actually never used the cutoff switch, always just the kickstand switch. I'll give the kickstand switch a little tap too for good measure, although the red light never came on, just the green one started flashing. I'm going to leave the error code display on too just for good measure.

Thanks and I'll keep you updated  :)

Hey guys!

I purchased my 2015 Zero S used (with 1k miles) in September 2018 and I love it to death. I'm a battery nerd, engineer, EV fanatic and couldn't believe I found one. Everything so far has been fantastic and I have put 2300 miles on it in the last few months (it is my daily driver).

Yesterday I left work and turned the key, got on, kicked up the kickstand and rolled on the throttle to get out of the parking lot. The bike stuttered (almost felt like there was ice or sand under the rear and I was getting poor traction). I let up and tried again and it was flawless the whole way home (about 15 miles). When I left for work this morning it did the exact same thing, but a little more severe. I stopped and the green "go" light was flashing. Once it turned solid I tried again and it was flawless again, all the way to work. In neither instance was I moving more than 1 or 2 miles per hour, it just wouldn't go.

My immediate thought was ABS initialization throwing something off, but I have no proof of that. I am going to continue to monitor it and record when it stutters, but I was just curious if anyone had run into this before or something similar? I live in Phoenix and the weather in both cases has been about 55-65 degrees. I've ridden it in much colder temps so I don't think it's dependent on that.

Thanks for you help!
