Vintage Toy Concepts The Super Models Keep Fit Cycling Machine doll with recumbent style bicycle fitness machine. Sized like a Barbie, this doll wears her fitness attire which is removable with the exception of her shoes. Simply press the button on her cycling machine’s display panel to get her moving. Music plays in the background as she counts off 1, 2, 3, 4 while pedaling her machine. SIMPLY DARLING! She easily attaches and detaches from her fitness equipment—her seat is magnetic, her shoes Velcro to the pedals, and her hands grip the handlebars. Her cycling machine requires 3 “AA” batteries, not included. On/off switch on the understand prevents accidental activation. Excellent condition—my daughter did play with this doll set so it’s not perfect but it definitely wasn’t abused.
