It’s said that you don’t forget how to ride a bike. It’s a somewhat true statement. If you have ridden a bike in the past and decide to start riding again, you have a slight advantage over the person who has never ridden one. Then again, maybe you don’t have an advantage. You rode in the past, but your final ride was horrific. You had to stop riding, not because you chose to, but because you were physically incapable of riding due to an injury. For you, the challenge is not in the pedaling but in the images and memories that fill your mind.
