Well, it all started when I saw a photo of a kids 10 speed, and started fantasizing about riding with my new godson. So I asked his mother if it was too soon for me to start thinking about a bicycle for him--

-- and she said no, and asked if I was talking about the Radio Flyers. I had no idea what she meant, so I went online and checked them out, and nearly died (see photo). I have to buy one. But then I started thinking that it's got to be for a really young rider, because an older kid-- say 5 or 6-- would probably get beaten up for riding that bike. I'm going to teach him Tae Kwon Do, and his dad is going to teach him boxing, but still, no need to needlessly hurl him into confrontations. So I figured the Radio Flyer must be for really young kids, and I started to think about when the right age would be to start him riding.
And I will instill some healthy fears into him. Always ride with a helmet. Always watch for cars when you're in the street (and NO street riding until he's old enough to understand the danger). Always make sure your front wheel is secure before hurtling downhill at top speed. That kind of stuff.
I can't wait.
