I really like the Reelight no battery lights (see my quick review here), but I don't care for the low mounting at the wheel axle.
Reelight announced a handlebar mounted version of their light at Eurobike, where Reelight has been nominated for a European Design Award for the secon year in a row.
The new light still has spoke mounted magnets on the wheel and a coil mounted to the fork to generate a charge to power the LEDs, but the light and housing have been moved to their own mount with a cable running power up to the LED light. The handlebar mounted housing is larger than the fork mounted light.
Info from Rad Spannerei (in German). If somebody can dig up a photo of this new light I'd really appreciate it!
