About 2 weeks ago I needed to drop off my truck for service. I threw a uni in the truck, drove the truck for service and tried to ride back to the office 1/2 mile away. .
Unfortunately every dam foss tube I have leaks and I started the trip back with low air pressure. I could hardly control the uni and fell twice.
Lesson: The wrong air pressure made the unicycle almost uncontrollable, and I was a hazard to myself, and the public.
Check your air pressure before you leave your pump! My knee still hurts!
