Opps...may have left the wrong impression. Front dynohub- driven headlight: the best option for LD rides. I'm just not convinced that the USB charger and rear lights are necessary. I keep my iPhone off except at night when I need the alarm. Even then, it's on only for a few hours. It'll last for 4-5 days like that! Peter know his stuff....check out Longleaf Bicycles if you want a custom-built front wheel w/ the dynohub option. http://www.longleafbicycles.com/. He's a little more...shall we say personable than Peter. . I'm a satisfied customer fwiw.
