I used to ride without a helmet, gloves, elbow/knee pads… But about a month ago I had a level 4 UPD.
I had gotten back from work and I had wanted to do some more riding on my 36er using 114mm cranks. I was still getting familiar with the uni in general, but at that point I had done a lot of riding on the 142mm cranks. I started riding around with the different crank setup, and I felt like I could push the uni a bit more than I could with the 142s!
Well… I got a little carried away 
I leaned a little too far forward, and just by reflex I started pedaling faster and faster (meanwhile I’m trying to lean back but my legs were like go go go). Soon enough I flew off of the unicycle, I land running way too fast, and I fall into a bad roll. Got some road rash and bruising on my hip and lightly scuffed palms… Could’ve been worse as I did ride away, but after that I decided I’d rather be safe than sorry
