Life is like riding a bicycle – in order to keep your balance, you must keep moving.
~Albert Einstein

It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.
~Ernest Hemingway

The bicycle is just as good company as most husbands and, when it gets old and shabby, a woman can dispose of it and get a new one without shocking the entire community.
~Ann Strong
