ISO: small pedal bike for adventurous 3.5 year old

We’re looking to borrow or buy a bike small enough for our 3.5 year old. Not sure how successful he’ll be but he wants to try it. I think we’d be looking for a 12” kid’s bike. If anyone has one lying around not in use - even if we can just borrow it for a bit while stores are closed so we can give this a try. Email me- allison.c.houck@gmail.com Thanks! Allison
