Nope! I'd ride what I can afford and any bike would be cool enough to ride under these circumstances.
I started on a Huffy. Couple guys I knew said they sucked but I was doing 60 mile rides and they were doing 20 on their Klein roadies (early 90's).
I learned more and got much nicer bikes ($3000 level), but I'm sure there are still other riders mocking my bikes. THAT! Is UNCOOL!
