I agree that you might bring your bike and some other gear with you, but be careful not to overwhelm. Some folks will be afraid it's too much of a $$$ investment to even get started. Of course others will be delighted with all the extra gear they CAN get for cycling. Same goes for cycling clothing--some may hesitate because they think they have to wear lycra shorts, while others will be just itching to buy some new clothes. So I guess you just need to be aware of your particular audience and what's most likely to appeal to them.

But here's another angle--daily exercise, including cycling, can limit some of the effects of aging. Have you ever read the book Younger Next Year? I thought it was just more diet hype, but when a friend recommended it and lent me a copy, I found that it has some sound advice. Most of us who cycle already know this, but others may not. Specifically, the authors strongly recommend exercising 6 days a week, and if you do this, they claim, it can actually not only stave off some of the most negative effects of aging, but in many people it can actually make the body behave as if it were younger. There's lots of science behind this claim, and you'll have to read the book to get into it, but it seems to me that many people are looking for ways to avoid a frail old age, and cycling is a pleasant, easy-on-the-body way to do that. BTW, one of the book's authors still cycles in his late 70s.

Anyway, just some additional ideas. I think you're right to plan what you want to include, but also be flexible enough to be guided by your audience's concerns. Have fun!
