From Jeff Lenosky, the “Trail Boss”:
This week I use the ramp I built in episode one and jumped with my friends in episode two to teach you the mechanics of jumping your bike HIGH or staying LOW and why you want to understand how to do both! Building wooden kicker ramps and landings is an awesome SCALABLE way to practice your jump skills. By trying different distances and different speeds you can learn all the nuance and input your body will have on the bike while jumping different distances. The take off is 38 inches high with an 11.5 foot transition and 48 inches wide. The landing is 42 inches tall, the downslope is 10 feet long, and the case pad is 2 feet. The overall width is 8 feet. I used 8 sheets of 3/4 inch plywood to cut all the sides and landing ramp surfaces and 2 sheets of 1/2 plywood doubled up for the ramp take off surface. The total number of 2x4s was approximately 20.
