I have never done cycling, when I was a kid I fell off bike for three times while I was trying to learn. I was so scared that I never tried again.

I still occasionally fall or wreck.

I use shoes that clip into the pedals for better handling and cadence. Now and then, people fall when they use those.

Wear a helmet to protect your head. 

But for the most part, injuries will heal.

I can't imagine a world where I wasn't riding a bike.
