バッグが未来型バイクに変身

[Generation Goal]
Generate a next-level transformation video where the woman drops her bag on the ground, the bag transforms into a heavy Tesla Motorbike, and she mounts it and rides away.

[Event Script]
At the start: A woman stands in an open outdoor setting holding a bag. She casually drops the bag onto the ground.
Principal event: The bag immediately begins a dramatic next-level transformation — it expands, reshapes, and morphs with glowing energy effects, metallic panels folding out, wheels forming, and the structure solidifying into a heavy, powerful Tesla Motorbike with sleek futuristic Tesla design, large frame, glowing accents, and solid presence. She then steps forward, mounts the fully formed heavy Tesla Motorbike, grips the handlebars, starts it with a low powerful hum, and rides away into the distance.
At the end: The woman is riding the heavy Tesla Motorbike away, bag completely gone, only the bike remaining as she departs.

[Maintain Consistency]
Keep the woman’s identity, appearance, and clothing stable throughout. Maintain a single bag that fully becomes the only heavy Tesla Motorbike. Ensure continuous spatial relationships and clear transformation sequence from bag drop to bike formation to ride-away. No other objects or characters appear.
