Re-greased my old motor with 1500 miles on it.
About 6 months ago I broke some spokes on my xpedition 1.0 and just bought a new rear wheel assembly real quick because the bike is my daily commuter, but I had every intention to fix up the old one so If something happened, even just a flat I could just swap the wheels real quick.
Finally got around to it this week, and figured if I'm fixing the spokes, I should re-grease the hub motor and replace the brake rotor because it had noticeable wear on it.
Any way, thought you all might want to see inside one of the 750W hubs after 1500 miles
the old grease was pretty nasty and stiff/dry.
If you watch hub motor service vids online, some are sealed with silicone sealant, some aren't. This one was not sealed, but when I reassembled it I used a little high temp gasket maker I already had around to seal it up.
I used Super Lube-21030 Synthetic Multi-Purpose Grease Just about any NLGI Grade 2 lithium grease should do it though. Other grease often recommended online is lucas oil red n tacky and Mobilgrease 28 aviation grease.
I went with super lube because its also marketed as a dielectric grease and that's always handy to have around so I have plenty of uses for any leftover.
Now I just need to get it on the frame and see about truing up the rim this weekend.
edit: lectric xpedition 1.0 spokes are 12g 128mm
adding this because I had a heck of a time confirming the 1.0 spoke size via Google. hopefully this saves someone else the trouble.
