Honestly Cig, if you think you can get this to work, do it. Do your research first and be truly honest with the folks that you are dealing with when asking questions. You won't get "real" answers if you don't ask "real" questions. Had you disclosed your entire idea to Trek, including how you planned on sourcing your bikes, you might have gotten different answers.

All this aside, there are tons of success stories to be told about someone starting a business venture where others said it couldn't be done. 40 years ago everyone would have laughed at the notion that an overnight package company could charge ridiculous rates so that someone could get a package delivered in one day. Today millions of dollars get spent on such shipping every single day.

After you've done your research and it still pans out, go for it.
