Context is everything. I ran a Shimano Alfine dynamo + B&M Lumotec Cyo RT for over two years on my last commuter (40 lux). My Surly DT is off-the-shelf, and buying a hub + rim + spokes + labor + light = $400 for a headlight that is bolted to
one bike for a short commute. I can move a portable light to my road bike for early morning work-outs, or to any of the other bikes at home.
