Design a gap jump and simulate the flight path at different speeds. Set your takeoff angle, lip height, and gap distance, then watch an animated rider launch off the kicker and fly through the air. The vehicle rotates naturally along the trajectory — nosing up on takeoff, leveling at the peak, and diving into the landing. Switch between BMX, MTB, and Moto presets for vehicle-accurate proportions, weight, and speed ranges. Physics include air drag scaled by rider + vehicle mass.
Real builds from people who ran the numbers here first.
“It is freaking great — scary, big, and when it comes right down to it, quite easy. Scary and easy, that is an unqualified good thing.”
