Dropped my bike earlier today, after losing traction while crossing wet tram tracks. Riding in the righthand lane, I began to change into the left, and the front tyre lost traction as soon as it made contact with the tram tracks. I knew what was happening and that I was about to go down. It only took 2 or 3 seconds before landing on my butt. A minor scrape to the inside of my left ankle and damage to the bike. It can easily happen to anyone, regardless of riding ability.
