What they said!

Another idea: Get him to ride a 50 pound bicycle with fat tires. It's a great equalizer

But don't be embarrassed about being nervous.

I am reasonably sure I don't have the responses to ride fearlessly, though they're better than they were. I do a great "deer in the headlights" thing when I'm overwhelmed, which means I'd crash. Even if I'm wrong, that is MY choice of the risks I choose to take. So, even though after oh, a dozen years (and the luck of big thighs) I've gotten strong enough to seriously embarrass people on indoor time trials, I don't ride on the streets with the people I can out-do on a trainer. Those rides freak me out.

Get stronger and faster on *your* terms.
