Being cooped up with the kids, we've been doing a bit of bicycle riding as weather allows. Nothing major, just mostly neighborhood stuff. We've got an assortment of cheap Schwinn mountain bikes from Target, etc that we've accumulated for the kids over the years and the darling bride bought me a very early Father's day gift, which is one of the Mongoose 26" fat tire bikes which was mail-ordered through Wally. I've done exactly zero maintenance on any of these bikes and would like to address the cartridges and wheel bearings as needed given (as I've recently read) they are not greased adequately from the factory. Never pulled one apart in my life! Countless tire/tube changes, brake adjustments, etc, is about it. I know it's not rocket science, but what's a good grease for these applications? Decent inexpensive tool kit for crank/cartridge work?
