The funniest almost always occurred during training and without benefit of a video camera.
During training everything after the first two hours is on the bike. Ride everywhere...even to lunch. While returning to the training area from lunch, after the "proper braking" class, one student panic braked (front only, rain soaked, downhill), standing his bike on it's nose and simply ran off of it......right into noon traffic.
It would have been easier explaining to the chief how I almost got a student ran over ON the bike.
Obviously, everyone thinks they know how to ride a bike...until you tell them to do something odd like riding down stairs, tackling a subject from the bike, or even shooting positions with the bike. All of them had to be able to "drop off" an 8 inch curb but raise the height just four more inches and most would not even attempt it. Actually had one guy seperate his shoulder "dropping off" a twelve inch platform.
Most of these guys (and girls) hadn't been on a bike in years. Third day - climbing - only 3/4 mile @ 4% grade, twice during a twenty mile ride. How many do you think made it out of a class of twelve? Only two. And all of them 15-20 years younger than the instructors.
Ever tried riding across a 4" beam ....4" off the ground, or turning your full size bike inside a six foot square. Very humbling I'll assure you. But by the end of the week we would graduate a new class.
