My dynamo hub seems to be slug? what should I do?

The power input/difficulty of running a hub dynamo can hardly be felt just by turning the axle. It is best to spin the wheel normally when mounted and observe the behaviour. When lights are switched off, the wheel, when turned with momentum, should make a few turns. If it stops already after one full revolution, there is probably a malfunction. Please contact us to discuss your problem together.
