Ahhh you're taking me back to my youth here. I used to do trials riding and was always on my bike. If I wasnt riding it i was fixing it, or upgrading it. Good times
Trials riding is an art form.
I had a neighbor whose dads did trials on a motorcycle in the 70's and 80's.
To see him from a dead stand still bunny hop a 125cc motorcycle 2' off the ground, with a seemless sideways table top motion to make the back wheel bounce off a tree at a near flat angle, goose the throttle and 180 off the tree... all in about what seemed like 3/4 of a second...the guy was amazing.
As time progressed he became a bull dozer operator who drank way too much beer. He ended up destroying one of his legs in a crash where in a drunken bet decided to jump his motorcycle over his bulldozer while it was still on the trailer that hauled it around, using the ramps on the trailer you use to drive the bulldozer off of said trailer.
He actually cleared the bulldozer but his leg apparently broke when he landed.
It was folk lore in my town for years....
