Rowan, are you saying because I've never pulled a fully loaded trailer behind a kids tricycle, I cannot approximate the sensibility of that experience? Calling fixie utility is a stretch and if it makes sense depends if the rider wants to put in the extra energy riding a fixie takes (i.e. also has a non-utility agenda like personal fitness). Most everyone else, I'm reasonably sure, are quite content to coast down the next hill after working so hard to get up it, and want some gears to choose from so they don't blow their knees out climbing it, and want standard brakes so they don't waste energy trying to stop (or get injured trying).

Fixie is for fitness, that does not mean an individual cannot use it for utility, but not reccomended in the general case. Is this a hard concept or something?!?
