In researching bikes for my girls, I see lots of people talking about balance bikes, but not so much about small bikes with training wheels that eventually convert to a two wheeler. Are bikes with training wheels just not a done thing anymore?

I'd like to get bikes for my DDs who are turning 5 and 3 late this spring. The 5 year old isn't particularly coordinated (she struggles with peddling her tricycle), but I think that it's a bit silly to buy a balance bike at her age. The three year old is significantly more in control of her body, but I'm not sure how big of a rider she's going to be, so I was hoping to start with something cheap and cheerful.

If you've got mid priced kids' bikes to recommend, I'd love to hear it! Thanks!
