Around a decade ago, I noticed that whenever 'dad' would come into the LBSuperstore to buy a new titanium flat washer for his Cervelo, the kids inevitably would play on the recumbents.
I'm not a recumbent rider. I do occasionally ride with recumbents. My observation is that people are really interested in recumbents, particularly teenagers. They probably would be put off by the price, but the interest is there. My son and his friend were really interested in building a recumbent a year ago, I haven't seen them since I banished them from my household for that.
