Basic maintenance is an essential cycling skill. Bikes are lightweight machines by necessity, so they can't be over-engineered for reliability. Bikes will inevitably break down on a fairly regular basis.

Fortunately, they're also boneheadedly simple machines to fix. You can learn to change an inner tube, align a derailleur, adjust a brake caliper and true a wheel in about an hour. If you have those skills, you can do 90% of your own repairs. You'll have an infinitely better cycling experience, because you won't end up stranded at the side of the road because of something that could be fixed in two minutes.

Indeed, and it's also a necessary skill if people are going to buy bikes online. I think it's pretty likely that a bike receives its initial adjustment and testing after it's assembled by the recipient. And I've read about quality lapses such as bearings with little or no lubrication, and insufficiently tensioned wheels.
