Seajay, that is true. We explain that. They get to see an example of a "racing" road bike and a hybrid that is steel, good for commuting, but lighter than a lot of hybrids. Since we sold our mountain bikes, someone else is donating their bike for us to show.
Actually, we talk about what bike is good for what type of riding you want to do. Most of the participants don't really even know a lot about the differences in tire size, shifters, etc.
I do give them a list of recommended books and shopping sites, local stores, etc.
