How long does a bike sit before wheels go out of round?

This is a newbie question, but I'm trying to figure out any issues with switching from one bike to another in anticipation of winter weather. Ok to sit through the winter?

Relately, is there any problem with storing a bike on its (cheap) saddle and handlebars? My lodging is space-limited and I can't drill holes for ceiling racks or anything like that.

Your bike is okay to sit through the winter. The tires may go flat but the wheels won't go out of round.

FYI, you can buy a free standing rack that will support two bikes. Or one that expands so that it wedegs between the ceiling and floor.

But your wheels will not go out of round supporting the weight of the bike.

My bike sat on the garage floor unused for 12 or 13 years straight, and it survived the experience... replaced the tires of course but the wheels were fine.

steel and aluminum do not creep at earthly temperatures. you wheels will not go out of round ever due to the weight of your bike.

Correction, steel and aluminum do not exhibit measurable creep at temperatures one would normally subject it to.

I wouldn't store a bike on its saddle. Floors - especially concrete - tend to be damp and a leather saddle will mildew and eventually rot.

yes mildew-- moisture--- dampness ---- make sure your ride does not sit around water or heat sources such as water tanks--- you could take off your wheels and wrap them-- wrap the seat too........ the less you subject your bike to the elements the better.....

Luckily (for this situation) the saddle is most definitely not leather. These are not super super nice bikes.

While we're on the subject, what about hanging from the rims by bicycle hooks in the ceiling? Same physics apply or is the force coming from the inside pushing out harder on the rims?

What is a ceiling hook gonna do that your fat ass doesn't? The bike weighs only about 1/10 what the rider does...

Yea, the weight of the bike does nothing. As I recall that was covered on here a week ago.

I can vouch that this is not always the case.

What originally prompted my question was that my father stored his bike upside down on garage hooks for several years and the wheels went out of true. So I was wondering what time period must elapse for that to happen. According to folks here, a winter is far too little time to worry about, so I think I'm set.

I'd say that's a safe bet. Just don't loan it to a circus that trains elephants to ride them. My racer sat for 12 years on alloy wheel on concrete - wheels were still in perfect true & round as they were before storage.

Really? Are you 100% sure that is wasn't untrue when it went up? I have no personal experience on this, but it seems very very very unlikely in my book. I had a crap steel rim from an old Wal-Mart bike that I wanted to destroy (I destroy things to determine their strength, like CF headset spacers - very strong BTW) and it took some effort to do the damage I did to itl. And by damage I mean bend a little. I cannot imagine weight from any size bike being able to affect one rim at all let alone two, especially when laced up with spokes to strengthen it.

Still I'm ll glad that I keep my bikes' wheels on the ground....

My bet is some kid was swinging on it.

Haha! I honestly don't remember doing anything of the sort. I suppose it's possible though. Anyway, I'm not reporting the results of a scientific trial, just an anecdote. If the general consensus is that it takes a bit of effort to get wheels out of true, then there's probably more security in that than in my single observation and experience.

Dannoxyz posted how he used his bike hanging by the wheels as a chin up bar, with no ill effects on wheel true. just saying.

ahahahahaha, funny. Ass weight is applied to the rims from the outside of the rims inward. The hooks pull from the inside of the rim outward in one concentrated area, didn't know if it might be better to let stand or hang.

Ass weight (1) is applied to the hubs, which pull down on the spokes and thus the rim. When hung, the weight of the bike (2) is applied to the hubs, which pull down yada yada... Same deal.

That weight is transmitted through and along the rim and resisted by 1) the ground through the pressure in the pneumatic tires pressing in equally around the rim (I think); 2) the hook which is located in one spot on the rim, but the load of which is distributed by the rim to all the pulling spokes.

The key is the material of the rim. It is metal. Metal doesn't flow like glass in response to an external force. It may deform by either 1) or 2), but in neither case is the deformation limit exceeded so it returns to shape when the load is removed.
