The RadWagon uses 26’’ wheels and tires and the frame is a unisex design meaning it fits a wide range of individuals. The frame is closest to a 17’’ frame on a conventional frame sizing chart and from our experience it fits well for people between 5’2’’ and 6'2’’ tall.
We do have a handy video that shows riders of different heights on the RadWagon, you can check that out HERE.
