I'm new to this forum. I was wondering what I should look for in a folding bike. Like what are the important factors I should be looking at (unfolded size, folding size, folding time, weight, tire size, number of speeds, etc.)? and what is a good spec number (eg. good folding size 2 cube ft? good weight 20 lbs?)? I know there maybe a thread like this already, but i didn't want to sift through the entire forum to find it, so i thought i'd just ask. Any advice is much appreciated, thanks!
