Speed and Mileage (Very Important!)

Dynamo-powered headlights don't work well below 8-10mph (depending on the hub and light). Dynamo-powered USB chargers don't provide useful charge unless you can ride faster than this for dozens of miles. Slow riding on singletrack or long climbs requires a supplemental battery-powered light.
