I just had my first flat at 968 miles. It was what looked like some sort of sharp fastener -- roof nail? In any case, I had Slime in the rear wheel and it was to no avail.

I'm not all that handy, but I checked out Rad's video on changing the rear and decided to try it. I made sure I got a torque wrench, an 18mm socket, and bought a couple of tubes. I was able to get it done first time, and it wasn't  as difficult as I feared. But boy did I get dirty.

Next time I do it, I am going to wipe down the tire and bike to clean it, and wrap the chain in a cloth. I washed my hands with Lava multiple times.

I recently started using the app MapMyWalk, and it appears that the odometer logs about 7% less distance than actual. I will try 28" and see if it makes it closer.

I also use a smart plug, but one attached to an Alexa. I named it "charger". Then I just say "Alexa, sleep timer 6 hours with charger".
