After 50 years of bike riding, I took a class today on how to ride a bicycle!
And it was great! I just can't believe how much I learned, and how much it increased my confidence levels. I had no idea how much there was to learn, how much I hadn't learned simply by experience.
We learned techniques for cornering, braking, riding a steady line, riding safely in tight groups, and more.
Maybe you guys know all this stuff, but my recommendation: if you ever have a chance to take a class like this, swallow your pride and go for it.
