With anything (particularly bikes), focus first on the problems you are actually having - It doesn't fit in the garage, you keep getting flats, the front wheel keeps falling off, the brakes don't work, it keeps getting stolen, there are terrible sounds, the gears don't shift, the seat doesn't drop low enough, your mechanic won't touch it, etc.

If our bike does what you need it to do, everything else is way down on the priority list.
