Physics geeks: Effect of unevenly loaded panniers?
#52
I usually ride with a mono-pannier, sometimes heavily loaded. The heaviest load was full of beer, up a very steep hill that required some out-of-saddle action. This does require a high degree of bike handling skill to keep the bike steady whilst you are stomping up and down but its a skill which can be learnt.

If I have two panniers with me, I'll distribute the load more or less if I can. Seems commonsensical.
But I don't notice a difference if I don't.
Maybe I would if rode really aggressively, but I don't do that. So for just riding around the city and on paths, I don't notice a difference if I just use one.
I dont think it makes much difference, but if it did, you'd probably only notice it in fast curves. So if you don't do that, you're probably ok.

You said it, bub. BTW, my daily commute is over the Hindu Kush, both ways, year round. I have to carry an RPG on one pannier and a mobile X-ray machine on the other. But the worst thing is the broken beer bottles left by drunken teenage coyotes and the "uneven kerbs".

I am not sure what my kayak weighs but I do know that I didn't have any issues with it.

I'm surprised no-one has mentioned the critical factor of the earth's rotational pull depending on which hemisphere you ride in. I know that when I moved from the Southern half to the Northern half, I had to switch sides I carried my pannier on.

Unevenly loaded rear panniers have negligible effect on handling. Unevenly loaded front panniers are annoying but not impossible to ride with. You'll not be able to take your hands off the bars at all, lest you immediately fall.
On the other hand, I can't ride handless (for more than 3 seconds) with evenly loaded front panniers either, so it's not as if it matters. This is not due to my lack of skill. I commute on a unicycle full time. With front panniers, once your wheel begins to tilt to one side, the weight in the panniers keeps it from easily being corrected.

No, you'd want to place the pannier on the left side of the bike. That way the bike will be leaned slightly to the right to maintain proper balance (center of mass over the wheels) and would then be closer to perpendicular to the road surface if that's crowned in the center.
Somewhat paradoxically, adding weight to the right side of the bike will result in added wear on the left side of the tire.

In a world of destabilizing factors , why NOT err on the side of stability? I rest my case your honors.
To err is still to make an error. Since the load on one side, properly secured, objectively has an insignificant impact on stability comparative to distributed laterally, and since you are making demands on others based on this error, judgment is for the defendant (OP).
If you indeed did call him a dangerous fool, you are directed to apologize.

In my opinion it's just an example of someone who doesn't know much lecturing someone else (cccorlew) who does. That seems to happen a lot with cycling.

No PhD in Physics, Just thousands of Miles Of Touring... balance the load by weight side By Side ..
But it's the Front panniers that matter more , you can ride with 1 rear pannier , for awhile.

Your office mate is a dork. In order for this to be an issue, the weight of the pannier'd items would have to overcome the forward momentum of you, your bicycle, and the loaded pannier. Unless you're loaded with 50lbs on one side and you take corners like you just learned to roller skate, then you'll be fine.
Ha! Just saw the date of the OP...now I'm the dork.

this sounds about right. ya an uneven load is uneven. if you were riding no hands eyes closed a gust of wind could certainly push you over. but seeing as you ride a bike i assume some amount of arm strength and ability to steer. so.....

I probably commented back when this was new. I still haven't bothered to figure out why a single pannier doesn't matter to riding a bike. A bike rider keeps the center of gravity of the bike in a vertical plane with the contact point of the wheels -- on average. This has to be true, or the bike would just tip over. This must mean that a rider with a single pannier leans to compensate, but I can't tell that I'm doing that.

I suppose you'd get a bit of tire scrub from constantly fighting it, but not enough to notice or worry about. If you can ride no-hands it's probably fine.
OMG zombees!

I think it's an asymmetry that borders on inelegance <wink>.
Manageable physics, but poor Feng-Shui, lol.
The guy who takes his one-sider on the train had a good point though.
