I used to train with battery free bike light old school double bulb bike fitted with halogen bulbs on a dynamo and a fitted fat bike tire comparison regulator.
I love the idea of the free power from a dynamo and the more powerful lighting I could run — but unfortunately I would fear for the life of my bike after investing in the front hub. Most dynohubs and lighting are not eye bikd.

Walter and Mathew — On the subject of drag, it is mostly negligible, but differs by manufacturer, whether the light is on or off and your current speed.
While the output is about 3W the drag is higher due to inefficiencies. A baggy jacket or position on the bike will be a much bigger source of drag.
The dynohub drag will be a little higher at faster speeds, but rider power will be multiplicatively higher e. Josh Williams Author — A minor technical error. The horizontal cut-off is done with mirror design not the hood on the top of the light. For those who prefer numbers, a battery free bike light modern generator hub takes about 3W or so… your average floor mount bike rack can put out watts no problem pedaling on flat land.
Do the dynamos add noticeable drag? The Schmidt battety about 1 watt when lights are off, shimano a bit more. Compare that with a normal commuters input of about watts.
When I give talks on All-Season Cycling I always talk about this option while recognizing that for not-yet-everyday cyclists, the expense can be off-putting. For anyone looking for a new bike that comes with front and rear dynamo lights pre-installed I highly recommend the Breezer Uptown 8.
