We generally don't spend that much on parts and accessories for commuter bikes. We're too cheap for that.

A dynamo hub for example might be cool, but then again I wouldn't care for the extra weight and slight drag. Not all of the time anyway. So a light plus battery (brighter than yours) is $20 not $470. Tune-up is free, spokes are a few bucks each (DIY). A cheap but serviceable rear wheel is half or a third of what you expect.

So, to answer your question: we don't.
