Abstract: A collapsible surf or sailboard dolly having the option to be manually towed behind one walking or be trailered behind a bicycle using a new and improved universal hitch attached to a bicycle. The bicycle hitch mounts generally horizontally to the bicycles accessory holes and clamped around frames chainstay holes. The dolly has a rear main wheeled support assembly strapped to a board. The main support assembly has wheels which are removable (in seconds) without the use of any tools. The wheels are held to the assembly with a Velcro and strap wrapping arrangement which positively hold the wheels to the main support tube. The dolly has a separate arm structure which straps to the nose of the board and is held onto the board by the wedging effect of the strapping arrangement. The rear support assembly is held to the board with the same wedging effect. A tightened center coupling strap causes the front arm structure and rear main support strapping to wedge over the board.
