It does not have quick release. You obviously unwind a lever on one side which unscrews the gear side from frame ... but once this is done there is no obvious way to me how to progress. All Scotts manuals ignore the issue making me think it is really simple (and I'm really stupid!) or has to go to the shop!!! unlikely
I couldn't find any images just a description. Apparently it is similar to a conventional skewer. The difference is, the skewer is removed to drop the wheel out of the frame. The nut that typically is not removed is captured in the frame. Some owners have complained it is difficult to line up the skewer with the "nut"
