Why Do We Ride?

Whenever I ride my bike, onlookers will pass all sorts of comments. Some will go "Wow, you look so good, so professional!". Some will say "Gosh riding looks like a lot of fun, I used to ride when I was young, I must pick it up again". Of course there are many that would shout "Hey, where can I get a bike like yours. Where can I get the assemble that goes with it?".
