Hi, ds is 4.5 and we're thinking of getting him a balance bike - he loves playing outside with friends, and had a small starter bike (from Mothercare) which he never really got the hang of peddling. I've heard great things about balance bikes, but all the ones I've seen are only for ages 2-4, and I don't want to pay a lot of money for something that he'll grow out of extremely quickly. He's not especially tall (just over 1 m) - does anyone have any recommendations over balance bikes for slightly older children?
