Hubs --Use good quality wheel bearing or lithium grease for lubrication, but we suggest that you grease the
hubs sparingly. Over-lubricating the hub will result in pre-mature seal failure, and an excessive amount of
grease in the hub cap/commutator. On an interval of 150 hours, 1-2 strokes of grease should be sufficient.
