The same helmeted adult BMX rider in the plain orange hoodie makes a small controlled hop from the shallow bank lip, keeps both hands on the handlebars and both feet on the pedals, and lands both wheels smoothly on the flat. Preserve the bicycle frame, wheels, helmet, face and skatepark geometry. Follow the rider with a gentle low tracking camera, without cuts, flips or spins. End at the supplied final pose and composition. Realistic short flight arc, wheel rotation, tire compression on landing and settling cloth. Native rolling tires, one soft landing sound and a satisfied breath, no music. No brands, captions or on-screen text.",
