The Knoxville Police Department is having their annual unclaimed bike sale this Saturday. The Department is selling all the bikes that have been unclaimed for longer than six months. Community Services Director Arlene Worrall says that the sale usually consists of between 60 and 100 bikes. She says they need to get rid of them because they run out of room at their storage facility. The bikes are sold as is and cost ten dollars each. Everyone purchasing a bike must have a photo ID and be at least 18 years old.
