Question: how has bmx changed over the years?
Answer: One of the most obvious changes over the years has been the level of difficulty of the tricks. Gone are the simple Endos, Cherrypickers and Bunnyhops. In their place are 540 Caballeros, Icepick Grinds and Double Flairs, which Robinson invented—it's two-and-a-half flips while soaring over a vert ramp.
