The bike wheel is covered with a tape with characters carved on it. When I ride the bike the wheel will print the words on the ground. It is usually an invisible concept, but when I pass through a puddle it will become visible. It's like someone repeating a sentence over and over as he walks, drives a car or rides a bike. While in motion he is writing and reading something at the same time. Here, I used a bike to print words on the floor of the gallery. This artwork can occur within daily life, or be an installation in a gallery. It could be done with a car, but in Tokyo , I had a bike and rode it everyday, so I used a bike in the how, and carved some words about sound on the wheel.
