Okay, I have a question about all this, too!

The book I bought on riding said to check your air before every ride. Um, no, I haven't. We aired up the tires (using an air compressor hooked up to my husband's car -- he carries it in the back end all the time) when we first assembled the bikes and haven't checked since. (That has been about ten days, now, and I've ridden 31 miles and he's ridden half that.)

How often do you check?
