Hello my friends here at the forums, I recently picked up a Paul Frank stingray bike, reminiscent of the Scwhinn Stingray Cruisers, my question is can I adjust the seat height on these bikes? Anyone have any knowledge? It looks like I can if you look at the rear in the pic, the rear bar has slotted holes seems like I fit them through the axle bolt however its a coaster bike not sure if that will change anything let me know please! Thanks!!
