J-hopping
n.— «To jump a pair of foot-high tree roots spanning a trail in Woodland Park, mountain bike instructor Simon Lawton uses a technique called J-hopping which, like the Ollie skateboard move, is something I still can’t get my head around. Approaching the first root, he leans his hips back, tipping the front wheel of his bike up and over the root. He then pushes forward on the handlebars which—and here’s the part I can’t quite fathom, though I watch him do it again and again—launches his back wheel off the ground. Voilà —he’s in midair, flying above the roots!» —“Outdoor-sports experts can help someone on your list get in the groove” by Mike McQuaide Seattle Times (Washington) Dec. 11, 2008.
