One of my main hobbies is riding motor trial. Trial means taking obstacles or driving a route that has nothing to do with a road. The key is not to touch the floor with your feet! this will result in a penalty. So it’s not at all a speed based sport but purely a skill/balance sport.
If you ever have the need to try it drop me a message and i'll take you on a nice trip :-)
More information and pictures you can probably find on my facebook page so have a look there if you are really curious.
