Any recommendations for free STLs to make 28mm scale bicycle “tokens”?

A set of bicycles to use as tokens to represent “this model is riding a bicycle” (rather than the suggested approach of using a totally separate model) seemed like an easy thing for even a cheap filament 3D printer to do, but looking around I couldn’t find any free options that fit within WW2 era (especially since accessories for real, full sized, bicycles are relatively common in searches for bicycle on sites that host these). Any suggestions?
