Let me add one more bit of advice here: Make sure your kid’s first pedal bike is relatively small and light weight. My 4.5-year-old was a balance-bike pro after 2 years’ practice, so we thought he’d be fine on a pedal bike. We got him one that was on the large side (but nominally fit him) hoping he would grow into it and keep riding it for a few years. But it was awkward and heavy and he didn’t want to try enough to really get going. After 6 months of no progress, the first pedal bike was stolen, and we bought him a much smaller lighter one. He was riding happily within the afternoon.
