Trials has always been crazy, but I think it's one of the only things that people do off-road on motorcycles that makes you think, "Jesus, they didn't try that in the old days!" There's FMX too, but that's something that's totally new. Trials has been around forever, but it just went nuts! Maybe BMX bikes have made it easier to start practicing younger? Bernie Schreiber was an artist at trials, but the guys in that video make him look like an amateur.
