As we go through life we begin to learn that some clichés hold true no matter what tests we put them through. "You never forget how to ride a bike" holds up while other sayings, adages and clichés crumble under the pressure of reality.
Although, your body never really forgets how to ride a bike, it is a good idea to check in with your cycling technique. Here's an easy way to improve your pedal power. Simply glance down at your legs the next time you're on your bike and make sure your legs are moving up and down - they should look like pistons. The up and down motion is the most efficient action for pedaling and will help keep you injury free. Don't let your knees wander out to the sides, keep 'em pointed straight ahead. As you ride, periodically glance down at your legs and correct any erratic motion. The more you practice pedaling correctly the easier it will become.
I fell in love with biking the first time I rode a two wheeler unassisted. I felt like I was flying down the street. So my other biking advice is to recall that childhood feeling of flying and to let all those adult thoughts fly out of your mind. Focus on how you are feeling and what you are seeing and smelling. Basically enjoy yourself; just be a kid on a bike.
