A humanoid goat with strong human-like arms and torso but a goat’s head, horns, and furred legs, riding a mountain bicycle at full speed on a highway. The bicycle leans naturally with gravity, wheels slightly blurred to show motion, and the goat’s body posture is forward-leaning as if pedaling hard. Muscles are tensed, veins visible on its arms, gripping the handlebars firmly. The goat’s hooves rest naturally on the pedals, creating a realistic physics-based balance. Roadside guardrails and highway markings stretch into the distance under a dramatic cloudy sky. Wind blows its fur and horns backward, emphasizing speed. Shadows, reflections, and tire contact with asphalt all follow realistic gravity and physics. Wide-angle perspective, cinematic detail, ultra-realistic motion blur.
