I have built my own bikes for twenty three years. First because I was poor, then because I could. Regarding inner tubes, you need slime. I never looked back. In a survival situation you want the simplest bike, solid tires, no gears and over engineered construction.

Edit: Like an expensive modern BMX.

When you build bikes, what is your starting point? Do you build the frame?

Thanks or the slime mention. Can't you simply buy slime separately and use it when needed?

You can buy slime tubes or core your valve (a simple task) and pour half a bottle of it in to a normal tube. I wish I built frames! No, about as intricate as I get is building wheels from bits (rim, spokes, nipples, hub and rim tape all on a jig).

If the shit hits the fan in a big way, bicycles will become one of the primary means of transportation. People will learn very quickly how to fix and conserve their own bicycles, because that is all they will have to get around on. I'm talking about a scenario where the gasoline stops flowing to filling stations, and the electricity stops coming to houses.

Every prepper needs a couple of good bicycles designed for off-road use and for hauling cargo -- gravel bikes, hybrids, hardtail mountain bikes with wide tires and a lot of mounting points for carriers. Every prepper needs to know how to ride a bicycle. It is not necessary to add that every prepper needs to keep himself physically fit, so that he is able to ride a bicycle when the need arises.

I'd say all that is really needed are a set of replacement inner tubes and a patch kit. Of course, a pump, but anyone who owns a bicycle should have a hand pump already. A basic set of hex wrenches and other bicycle tools, such as a chain whip and a pedal wrench, are also essential. A bike stand for working on the bicycle. Maybe a spare chain and spare brake pads.

I would add groupos, rings and extra wheels etc.

I am outside the USA and I order extra parts to have on hand as shops here are tiny and haven't the inventory to do normal upgrades.

I was hit hard by hurricanes Irma and Marie and the bike shop couldn't repair my damaged bike due to huge number of damaged bikes in the shop. Suppose re-supply were ended... think hard what would you need?

I go thru big rings annually (mtb).

Note to beginners - fancy race bikes have no way to attach racks. Look at touring bikes or at least look for rack attachment points.

In the tools dept. I suggest also a crank puller. And, for beginners ... know spokes are a math test for repairmen. Just get a few extra custom cut spokes as replacements in advance. Buying un-cut, un-threaded spokes will be a hassle as there are many configurations to make them fit. JUst get a few custom made if you feel you will need them.

Don't count on electricity to watch repair vids. Have some books on hand.

snow conditions -

I had good luck with normal 2" mtb tires in packed snow using tire chains made for mtb. I think they still sell them.

Air is "smaller" in cold conditions and you have to pump tires by feel.... and be sure to let air out if you take the bike indoors ... otherwise scary, delayed tire explosion. Sounds like someone shot a gun at you in your house.
