Input:
Ordered this bike on Amazon and it arrived 24 hours later. Love the classic styling and the durable build and it was fairly simple to assemble. The seat is solid metal so perhaps a cushioned seat would be better. My son is 26-months-old and he loves it already. Only problem is that he can't reach the pedals (and he's tall for his age). Other reviewers have had the same problem so when my son is taller I'm sure he'll love it even more. Also agree with other reviewers about the bike being top-heavy and prone to tipping over but that's typical for an old-style tricycle. In the meantime I'll have to buy him a bike that he can actually use.
