Just wondering if others have the same experience. Today after about 80miles of riding it in city, I noticed significant slowing which I confirmed with the app. Max speed is 11 mph, as opposed to 15 which has been the case. This is concerning as the battery shows another 9 miles charge (over 50%). I suspect it is a battery issue, which is not expected this early on. I have already checked the regenerative option, and set it to weak, with no noticeable improvement.
Is there a way to test battery health without significant hacking?
