Funny story, a few years ago, I did an 85-mile ride organized by a local club. I rode my commuter, a.k.a. my only bike. It was a city bike (IGH, dynamo hub, etc.) with a list price of about $1,200. To me, it was a pretty expensive ride, but wow, did I catch a lot of attention for doing a long ride on such an inexpensive bicycle. Maybe it was also the regular clothes? The other riders had $3-4,000 bikes, padded shorts, Lycra jerseys, the whole kit.
It wasn't even that taxing of a ride, on a rail-to-trail with basically no grade, done in about 7 hours!
