Our team picked bicycle after discussion and came up with three ideas:

Rusty Bike
      A rusty bike pulls out of a forgotten corner, and as the bike moves and the tires turn, the rust from the bike flies off revealing a brand new pretty bike

Electric Bike
      Vintage bicycle is going down the street during daytime, then the time and environment changes to the city at night where the vintage bike transforms into an electric bike and speeds up leaving a trail of lighting behind

Mystical Bike
      A bike is going down path, controlled by magic yellow particles as it spreading life around.

Eventually, we picked the rusty bike idea as our main focus.
