Winter Cycling Tips:

Studded tires make riding a bicycle on ice much safer. The front one insures you won’t fall on your face, the rear one helps give you enough traction to move forward.

Full coverage fenders will keep your bike significantly cleaner, which means it corrode far less. And they keep snow/slush/water from flying up at you too.

Cold drains batteries much quicker. Consider getting a dynamo lighting setup so you don’t have to rely on batteries.

Your body generates a significant amount of heat while cycling, so it is best to dress so you will be somewhat cold the first mile or two, then you are more likely to be comfortable for the rest of the ride.

I’d rather imagine a world without monarchs, but with more opossums.

Overhaul as in pull the bearings out, clean them with degreaser, then inspect them. If the bearings are not pitted and the retainer isn’t bent out of shape, you can reuse them. If they are messed up, they are very cheap to replace, many bike shops will have replacements on hand. Once you have cleaned or gotten new bearings, pack the cups they sit in full of grease, and reassemble. Typically bearing retainers will have a side that is more rounded and a side that is more flat, you usually want to put them into the cup rounded side facing in.

Once you have it back together, you want to adjust it. The goal is to have the bearings be as loose as possible while not having any play in them. You also want to make sure the locknut is tight against the cone.

This page has info that will be useful for the bottom bracket.

Pro-tip: These bikes usually come with little to no grease in the bottom bracket, headset, and front hub. I would recommend overhauling them sooner rather than later if you want the bearings to last.
