I would not have bought that particular pre-built Luna without riding it. I just happened to be in the same place as the bike, so it worked out. I would (and eventually will) order another Luna from Margo from afar. This one will be custom made for me. Don't start yet, Margo, I have a kitchen to finish paying for!

I don't know what to tell you about trying bikes. If you get to the point of knowing all the geometry, you can really narrow it down. But I would still want to ride a few before I spent money on a bike.

In any case, you are really gaining alot of knowledge so that when you DO find bikes to ride, you will be armed with great information, maybe even more than the salesperson!
