As for HelMart bikes, the amount of grease used in them is about the equivalent of what you could rub off a teenager’s nose. Seems like a lot but it really isn’t.
Other prophylactic measures I would take would be to replace the bottom bracket or at least the bearings. The bearings and cups are made of slagnesium which has all the strength of wet toilet paper. I’ve seen a number of bottom brackets in the co-op where the cups pull apart when you try to remove them. Makes it seem like the cups are cross threaded but they really aren’t. Bearings often come out as hemispheres
Hubs and headsets don’t seem to be much of a problem in my experience but they have more of a sheen of grease than actual grease in them.
I haven't gotten to the bracket yet, I've been dealing with the hubs. There was brown grease in there though the amount seemed a bit sparse to me. I lubed up the hubs and the freewheel. The dishing on the rear wheel was off, spoke tension was all over the place - stuff like this is exactly why I'm going through it, amazing they sell bikes in that kind of adjustment. However I will say the rims do true up pretty nicely.
It's been sitting for around three years but I don't think the spoke tension would change that much with -0- stress being put on it.
