Boys Pokemon 6-Speed Bicycle Mountain Bike with Falcon Index System RARE HTF

This Pokemon Bicycle is rare and hard-to-find.  It was purchased directly from the Pokemon Center in New York several years ago.  It was only used a couple of times, as can be seen from the like-new tread on the tires.  It has 20" tires.  It has been kept in a garage, protected from the weather.  I am not sure why there is any rust, but there is a very small amount as pictured in the last picture.  Feel free to email any questions.  Thanks for looking!
