Turns out the tires are more solid than I thought so I just picked up some tubes at the hardware store ( standard kids bike size ).
It feels good to be riding this again, during the warmer months I've got an electric scooter to hop around my little town but prefer a less weather vulnerable bicycle the rest of the time.
Like this Dahon stowaway because I can just fold it up and leave it there with confidence that nobody will know how to unfold it and ride away, it's literally the only folding bike in town
Those white walls do look nice so I'm still contemplating buying them some time in the future, but they're not needed at the moment.
