Please help. I will also be happy to read suggestions about bike size. He just turned 6, is 50 pounds and about 48" tall.
Go to a good bike store, such as those stocking Trek, Cannondale, Specialized and Giant. Have them fit him for a bike. Based on my own experiences, I'd suggest a one-speed bike with a coaster brake, ESPECIALLY if the bike will ever be used on a public street.
Kids from six to nine often get "tunnel vision" where they are thinking only about ONE thing...such as going faster. Thinking about the cars coming toward them, the cars behind them, the left hand brake, the right hand brake, and changing gears...that is about four things too many to think about.
And, a "name brand" one speed bike is "bullet proof". Just keep air in the tires. Nothing to adjust or tune. Nothing that will need fixing. A "point and go" bike.
Actually, I've been riding a single speed bike a lot recently myself. It is nice to have a bike that you just pedal and steer. A simple and relaxing riding experience.
DO NOT buy a bike from Wal-Mart, K-Mart, a sporting goods chain, or a toy store. Your kid's health and safety is worth far more than the $100 price difference between a Krap-Mart pretend bike and a REAL bike from a REAL bike store.
