Jay, If this trike were shipped in it's present configuration, you would have a package 36" wide x 40" high x 62" long --minimum. If the wheels were removed, the package would measure about 36" x 32" x 44". Still a big box. If you could talk the seller into shipping the trike, have him ship the wheels separately. He is a nice guy; you might be able to work something out with him.
Good luck, Paul Patzkowsky, a trike rider in Longmont, Colorado
