I got my kid when he got big enough to handle it, a bike that has removable pedals and chain, i.e. the https://www.press.bmwgroup.com/global/photo/detail/P90224119...

He switched seamlessly from løbecykel to this one with the pedals removed, it was just the same thing, only a bit larger !

Then when he got comfortable with it, I added back the pedals. He got the hang of pedaling in ~10 minutes and a couple of runs down the street. Ever since he has been bike-mobile ! Never even thought about helper wheels.
