Oh gosh, I remember my test ride... well, I only test rode one bike... it was the one in my PRICE RANGE.
Anyways, it was scary. I hadn't been on a bike in years, and that bike was FAST with skinny tires! I went slowly... but it can nerve racking! Especially if you aren't sure you can afford to break the merchandise!
So, after I am done with my test-ride-of-terror (OK, I'm being a little dramatic)... I go to get off... and I FALL OVER!
My stinking tennnis shoe (yea, the guy told me NOT to put my shoe in the cages) got caught and I wasn't able to get it out before I tipped over to the right.
That prompted me to buy clipless shoes and pedals. So, I have been riding with those since day 1.
Good luck bike hunting and hopefully you won't tip over like I did on the test ride.
