Adjustable wrenches in general are not "great" in the sense that they grip only on two flats, as opposed to proper wrenches that grip on more. Thus, there's a greater chance of stripping nuts or bolt heads.
That being said, it's not like you're constantly removing the wheels. I always carried a 6" adjustable to take of my kids' bolt-on wheels when we rode, and it was light and perfectly fine for the job.
