Solar Bike Dawn Ad

Create a 12 seconds natural commercial video featuring an electric cargo bicycle on a coastal morning route in a cinematic near-future city. Story progression: Start with the bike leaving a quiet courtyard, follow along the coast and finish as it parks beside a market opening for the day. Camera plan: Side vehicle tracking with one gentle front arc near the destination. Motion behavior: Believable wheel rotation, rider posture, cargo weight and road speed. Sound direction: Freewheel, wind, tires and distant market setup. Use coherent screen direction, physically plausible momentum, stable subject identity, consistent wardrobe and lighting, and a clear visual endpoint. Required constraints: No speed claim, impossible battery indicator or unsafe riding behavior. Do not introduce cuts unless requested, do not morph faces or products, do not add illegible text, and do not imply a real endorsement. Deliver a 9:16 vertical version unless another format is supplied.
