Probably due to incorrect ground. The temptation to use the frame as ground must be resisted with LED lamps driven by a dyno. The AC to DC conversion only works correctly when both leads from the dyno hub are connected directly to the LED lamp.
(If the frame is used as ground for the dyno hub and the LED lamp then the AC to DC conversion is not a full wave rectification, rather it is half wave and less than 1/2 the overall power. Combine that with a supercap standby circuit that must be charged up before the LED is turned on means it takes a few blocks to charge up the system.)
