In his latest video, Destin Sandlin of Smarter Every Day tells the curious tale of how a special bicycle with mechanically flip-flopped steering ruins his ability to ride a normal bicycle. The story begins when a welder friend gives Sandlin a bicycle with reversed steering (left is right and right is left). The seemingly simple adjustment renders the bike completely unusable to Sandlin as well as every other person who tries it. Frustrated but undeterred, Sandlin practices with the bicycle for eight months until he learns to ride it. But when he tries to ride a normal bike again, things get weird.
