Trials rider Danny MacAskill (one of our favorite athletes around these parts) has recently started sharing some behind-the-scenes looks at some of the coolest tricks he's done for his videos. The video above shows him trying to barrel roll his bike with a trailer attached, which he likens to "doing a rally [race] with a caravan on the back". What's fascinating is that it takes him forever to get the maneuver down, but once he does, he's able to do it over and over again — "gradually, then suddenly" in action. You can see the finished product in his Danny Daycare video.
Two more behind-the-scenes videos he's done so far: the backwards roll and the log slide (which also takes him forever to do but he's then able to repeat three more times in a row).
