I'm not really very mechanical and never will be, BUT Ladies, please learn to change your tires. That is one thing you don't want to leave to chance or wait for your husband, or friends to do. It really is NOT that hard. Most bike shops will show you how.
Then go home on a cold winter's night (or a hot humid night) in your living room and both tires on your bike at least twice. This includes taking them off the bike and putting them back on the bike!
It is not safe to ride around by yourself without your supplies to change a tire and then be sitting on the side of the road stranded having to rely on a stranger to change your tires!
PLEASE, learn to change a tire!![]()
