I like that they have a great selection for the benefit of their customers. Those options are helpful whenever you are a little out of a band, they will find what suits your bike most.
When I bought a bike on Craig's List for $50 that needed some work, I was a bit worried. I didn't want to hear that I should buy a better bike. I didn't want to be overcharged for what I knew were simple repairs. I didn't want to have to leave the bike (which I needed right away) for the weekend. None of this happened. Brad Adamson listened to me, fixed what was wrong, didn't try to sell me anything, and had it finished by the afternoon. And he certainly didn't overcharge me. Now I have a bike that I can ride to school with my son. Perfect.
