Sometime right around when I broke my wrist, by back bike tire also went flat (very empathetic of it!) … today (almost three months later) seemed like a good day to fix it! In the above photo, the back wheel is off and the old inner-tube is out (these steps undertaken with the help of youtube videos). In the photo below, the new inner-tube is in, and the wheel is back on: woo-hoo!
And in the photo below, the bike is back from a short test spin!
