Mr. Trout: mine are friction shifters, but are not on the down-tube. they are at the point where the handlebars meet the body of the bike, like in that picture I linked to. I just went on a ride for a few miles around the park, and it was very nice. That bike collective you linked to is the place I got my bike from. And it wasn't $10, it was $160. I got a rear light, and they were out of front lights. I do not plan at biking at night anytime soon, considering how nerve-wracking biking during the day was. Even just crossing a street to get to the park, and then riding along a 2 lane road on the way back was a little more than I wanted to deal with at this point in my biking career.
I think my highest gear isn't high enough, but that might just be that I'm not used to riding a bike.
also: STL drivers being really unassertive and wishy-washy is even worse when it is difficult to accelerate/decelerate quickly.
