My almost-four-year-old is currently riding a 12-inch pedal bike that I bought him at Goodwill. Because he is small for his age (3'1", or 25th percentile), I do not expect that it will last him until he is big enough for a 16 inch bike, and am thinking of getting him a "nice" used 14" bike.
Any brand suggestions for 14"? The idea is to set up a Craigslist alert for a good brand, but I know that some of the best brands (like Specialized Hotrocks) do not come in that size.
