Na batteries fine. I did learn several things today on my 25 wide tires on mile ride. One the rear tire was down to ten psi and I think that may be where my mileage went. I hadn't put air in it since last year, it's back up to 15psi now where I usually try and keep it. It sure rode smoother with 10psi. Found out of I get close up to the display and way way off to the left I can read it. After my ride of 25 miles I had exactly half charge left or 47.4 volts. I did not have the trailer with me today. Turns out I've put a few more miles on than I had realized, 764 miles after todays ride. Dang bike is a pure joy to ride! Once I get it up to 2400 miles I figure I'll call it paid for! LMAO So I'm almost 1/3 there. hahaha
