I'm new to the forum (did introduce myself in that thread), but I have recently done some test rides so thought I would share.

No one from the LBS came with me. They just told me where to ride around the shop and sent me out. (Bring your helmet. If you are going to multiple shops or anywhere after your test ride, be prepared for helmet hair). Some people suggest bringing your own saddle, if you have one you like, and even pedals, but I didn't. I had to leave a drivers license at the shop.

I spent a good while on each bike trying out the gears, finding hills to go up and down, noticing how easy it was to shift and brake, and how it felt as far as size. One sales guy said he thought I might have gotten lost on my testi ride! I would then go in and comment on what my experience was on the ride and get various comments in reply ("yeah, that one does have pretty low end gears", and "we can make it fit"). You do want to know how they do fittings - if they do fittings at all.

It was pretty easy to rule out some bikes in the first few minutes based on the test ride. Some things you aren't going to know until you're on it for 20-40 miles. I didn't ask for and don't know if a lbs will let you take a bike home for an extended test - I'm sure others will know. I think if it feels good on a good test ride - or maybe several test rides- then you can probably adjust for any discomforts that show up on longer rides, at least I have been able to.

I ended up getting a Trek 2.1 WSD which felt great on the test ride. I'm very happy with it - and it was on sale I think I have gotten the bike right where I want it now after taking it back in for a few adjustments for fit after some longer rides and fiddling with the saddle myself.

Good luck! I know you will get good advice here.
