I had a lot of trouble putting the rig together, it took me forever, actually. The seat being nearly impossible to get right, and scratching it up. I finally got it, out of dumb luck it seemed, without it being crooked. The seat also is a wee bit small, but I'm getting used to it and it's chill. The seat adjuster bar also was giving me a hard time, as I needed to adjust the very tip of one end in order for it to sit in there right, that part definitely needs redesigning. Plus all from question 1
