The only thing you need to watch for is water contamination and
that is easy to see, it will turn the grease white, or whitish.
I use grease for boat trailer wheel bearings, because I have a
boat trailer and there fore, the grease. LOL! It has and
indicator that turns white when there is water.
Bikes don't need a great volume of grease. Old bikes had
an oil port and the hubs had cotton wicking in them,
the rear coaster brake needed oil, 3-n-1 was the standard.
