Odd Japanese Pictues: Bike in the Air and Canada Fair

Here is another funny picture that I have decorated in my office space:
When I went to Fukuoka, I saw this bike hanging in the air, and I wonder why it was there and how it got there.

This is also from a few years ago (2002), they had a Canada Fair in Sendai, and I happened to come across it when I was backpacking in Northern Japan.
