I've been slowly adapting my Raleigh to my own tastes and utility for urban commuting. My route is not long (3.5 mi each way), and the typical hazards I deal with are pretty crappy roads (including a little bit of cobblestones), weather, and your typical road debris. For work, I have to carry a laptop to and from the office. When I've ridden a motorcycle to the office before getting frustrated with traffic along the same route, I had no qualms about throwing the computer into saddle bags draped over the passenger seat. But on a bicycle, I'm a bit apprehensive about getting panniers as I'm worried about the shocks. I don't want to slow down or take it easy and my relatively short distance allows me to have fun and my back and shoulders aren't bothered by my messenger bag. Still, if there was a reliable way to keep the computer fixed to the bike and safe from shocks and moisture, I'd prefer it. Any words of advice or experiences?

I have carried my laptop around in my panniers. I do not have to deal with weather, and I do not do it regularly. I would think for everyday that a backpack would be safer in terms of exposing the laptop to less abuse.

I usually place the laptop in its bag and use a pannier....no issues in several years.

Yeah: put it in your backpack when it rains.
If I'm carrying something expensive or electronic, I like to put it in my pocket or backpack. The realistic chances of damaging a laptop in panniers are slim, but it just makes me feel better.
I use panniers for bulky stuff: clothes, books, bags, tarps/blankets if camping, etc.

Have carried my laptop for years in panniers, no issues, even when I crashed onto the side of the pannier carrying the laptop at 10 mph.

I would definitely use a back pack for the laptop, but I have hardtails and bumpy roads. Laptop hard drives are tough but I wouldn't jeopardize it.
Just be sure not to start a defragger before you set off ;)

Wrapping your laptop in a jacket should take care of the shocks in the pannier. Otherwise I carry my laptop in my backpack if I think it's going to be knocked around.

Thanks for all the replies! I think I'll keep using the messenger bag / back pack for the laptop for now, but I won't be as worried about stuffing one into a pannier, provided it's cushioned. BTW, one thing I've found to work well for water insulation is bringing a plastic bag with me and putting the computer in it if I know or suspect there'll be rain.
One other thing I was thinking of trying specifically for electronics on bikes without suspension is to take a small bag -- something like a specially made laptop bag -- and attach sections of old inner tubes to it and then run the other ends of the inner tubes to the frame of the bike and let the bag be suspended in the middle. Will try this idea with some test payloads and report back here.
I'm look seriously at the Ortlieb waterproof panniers. Put a laptop in a good case and place it those panniers---I'd bet the probability of serious damage to your computer would be very very low. And of course back up your computer!

I use a pannier to carry my laptop and other stuff (clothes, lunch, etc.) and I like that better than a backpack. I found the backpack made me too top-heavy and it made it too hard for me to look back left or right without losing my balance. Plus, I have some back trouble and its better for me to keep excess weight off my back (YMMV).
Most panniers do have some give/bounce which helps absorb potentially damaging bumps. After 3 months of travel like this (several hundred miles) I've had no problems yet, and this includes one accidental fall where the laptop-side of the bike hit the ground with no damage to the laptop. Again, YMMV, and I will say that my route is probably smoother than yours--no cobblestones for me, thankfully.
I put the laptop in a neoprene waterproof laptop sleeve which is a good protector from water and vibration and most bumps. The sleeve came with a thick foam insert (the size of a laptop) as packing material, and I use that as additional vibration absorbing material. I put the foam insert in the pannier bag on the bike-side. This is what I bought:

One thing I've read is that laptops with SSD are more resistant to the rigors of bike commuting than traditional hard drives, which have more fragile moving parts. So, if you don't have a SSD, get one. Not only will it be more durable, but your computing experience will be much faster! The only downside to SSD is they're more expensive and have less storage. Unless you have to store large amounts of data on your laptop, then this is not a problem for most people.
FYI, I use the Bontrager City double pannier and it fits a 15" laptop with protective sleeve just right.

If I pack everything carefully, and put my clothes in ziplock plastic bags, I've never had anything get wet.

I have carried various laptops in my panniers for 15 years now and it has never been an issue as far as keeping it dry. I use Ortlieb panniers and nothing ever gets wet. They are the best as far as being water proof. I've crashed twice and neither time did the laptop get damaged. Which really amazed me since one time the bicycle was totally destroyed. The damage to the bike was front wheel destroyed, front fork destroyed, cranks bent and finally rear frame bent. No damage to myself either so I count myself lucky for both the laptop and myself on that one.
I struggled with this once, when I still had a job and enrolled in the local community college. I ended choosing the backpack, primarily due to limited funds and the multimodal commute (bike/bus). After about a week, I discovered flash drives and how to convert Google Docs into MS Office format :D

That's what I do too. I always have a couple of garbage bags in the backpack. One goes over the laptop if it rains, another might come in handy for anything else. I have a 17 inch Lenovo that weighs over 10 pounds without all the extras.
I put up a page with more backpack details at a bike and a backpack (http://mainlytext.com/bike/backpack.php).
I really like backpacks and have never used panniers.

That crash info is very interesting. No doubt, it sounds like a high impact event and it's probably very good that your fork, wheel, and parts of the rear triangle acting like crumple zones and absorbing some impact.

Thank you for all the info! One thing I will say about messenger bags is that it used to hurt my upper body musculature (shoulders, thoracic vertebra, etc.) until I realized what I was doing wrong. Initially, I would tighten up on the shoulder strap to secure the bag and then buckle the waist strap, but not too tight. This would of course cause the weight to be carried by back and would hurt no matter if I used the bag on a bicycle or motorcycle. One day I had an epiphany -- the shoulder strap is not for supporting the bulk of the weight; rather the waist strap is! Once I tightened the waist strap so that the bag would ride primarily on my hips and then have the shoulder strap just barely tight enough for the bag not to flop around, the pain and discomfort stopped and never returned. This is why I'm in no big hurry to find a better alternative. My back is happy, if I can get the weight off my hips now, it'll just be icing on the cake.
For those using backpacks or messenger bags with waist straps, take heed (if you don't already know). The next day after my moment of enlightenment, I enthusiastically told my wife and she said, "You only just realized this now?" Yeah, I'm not the brightest knife in the shed sometimes...

i am pretty sure your laptop weighs the same amount in my large waterproof ortlieb back pack.
imo, those who ride aggressively should ditch the panniers. they are fine for a grocery bike or a tourer but when mixing it up with the cagers i want my center of gravity to be underneath my legs.

I've had zero problems over the years with riding w/ panniers & aggressive riding...
IMO if you're riding aggressively the best option is to carry nothing, no panniers, and least of all a backpack with all that weight on the back, neck, and shoulders.

I hate transporting my laptop on my bike, but if I must, I like a backpack as our roads are terribly bumpy and I feel like the machine takes less pounding through my body than hanging on a steel bike frame. I guess my body adds one more layer of shock absorption, at least in my mind.
I am not sure that laptops even care about getting knocked around a bit. Certainly the ones with solid state hard drives are not bothered by a bit of rattling in a pannier.

I would use a backpack, but I stop a lot and do errands on commutes. For example I leave work, then if I stop at a walgreen's or a grocery on the way home it's much easier just to lock the bike and dash inside rather than worry about stuff I have in my panniers. But if I'm not going to stop somewhere it makes no difference to me :)

that's what's great about the Arkel Bug. It's a neoprene sleeve that hangs in the bag so the laptop is suspended in the neoprene which acts as a shock absorber.

Used a pannier for years until this summer when the corner of the laptop got into the spokes. Ripped the corner of the lid to shreds, including the display. I was in traffic on a bumpy road,and accelerated hard to keep up. Now I use a backpack.

There is a Timbuk2 shift (http://www.rei.com/product/811082/timbuk2-shift-pannier-messenger-bag-medium)that is a messenger bag that will allow you to hook it to a pannier rack if you want. I started another thread in this forum much along the same question as I am a student and commute to school and then work from I needed to be able to carry electronics and personal items.
I looked at the Arkel Randonneur (http://www.arkel-od.com/us/all-categories/bicycle-bike-pannier-rack/arkel-randonneur-rack.html) there is a weight limit on it of 13lbs.
I think I am going to end up purchasing a Chrome Metropolis (http://www.chromebagsstore.com/bags/messenger-bags/metropolis-buckle-bag---large.html) then stitching a piece of webbing across the back much where an x-strap would attach what I can mouth hooks to that will allow me to mouth the bag to a pannier rack if I choose or where as a traditional messenger if I want also. Might not be the best fit for you but for me I think that will give the flexibility I need or want.

core strengthening.
What do you think will give a lower COG than panniers? your backpack?
will putting more weight on the extreme end of a seesaw result in a more centred balance point? i prefer extra weight in the middle of my bike.

The biggest difference in terms of mass distribution and handling in this argument that I see is not so much where the cargo like that is, but what it's doing. Unless the panniers are utilizing some shock absorption devices of their own, their content is unsprung, to borrow the term from automotive lingo. In other words, that weight is doing whatever that part of the bike is doing. On the other hand, your backpack is, well, on your back. If you go over some rough stuff, chances are you stand up on the pedals and let the bike dance around underneath, while your upper body and your precious cargo floats along, as though on a cloud made of kittens. And who doesn't want to be on a cloud made of kittens?

The point is that with your weight high, it's less safe. There is no doubt that riding with a significant weight high on your back is worse, less stable, less safe than having that same significant weight down low.

try track standing/sitting with 30 lbs in a pannier and then try it with 30 lbs in a back pack. the last thing i want on my bike is to be off balance when i make an emergency lane change at 20-30 mph.

100% disagree. i have made emergency stops on a bike with panniers and they are hardly unsprung. the other problem i have with panniers is that they sit right next to my whirring drive train. we all know people who have eaten pavement because some part of their pannier has gotten tangled with...

I think you mistook the thrust of my post. I was actually highlighting the benefits of carrying payload on your body.

I generally have no need to do track stands on my commute. Loading the panniers off-balance can usually be mitigated by either not doing so (distribute load as evenly as possible) or with body english. Similarly, there are issues with stuff on your back not always being centered or what have you. Either way, I do not see a big issue making quick steering changes at high speed so long as the weight is secure. I have more trouble with stuff that's moving about, such as when I elect to carry plastic bags dangling off my handlebars or wrists or if I'm on a tall motorbike with a large tank about 2/3 full of gas and I can feel it sloshing about.

Not sure what you're disagreeing with. If a pannier is solidly or nearly solidly secured to the frame of the bike with no foam or some springing device inside the bags, and with no suspension on the bike, then the weight is unsprung -- by definition. If the panniers are allowed to move around -- either controllably or not -- then that weight is at least partially suspended. There can be benefits or disadvantages to either.
As to the panniers getting tangled up with spokes or sprockets, all I can say is pay attention and make sure the panniers are well designed. I've carried all manners of stuff on bicycles and motorcycles strapped close to the rear wheel and drivetrain and only had a problem once, which was 100% due to my own stupidity. Whether we elect to have stuff strapped in that area of the bicycle or not, paying attention is important -- from maintenance and inspection of your gear to how you ride. Stay alert and healthy!
Happy New Year, everyone!

I like the panniers because all the weight I tend to carry up high is unstable and I think it is better to have the weight lower.

Regardless of where you transport it you can expect reliability problems like failing solder joints and CPU thermal interfaces.
I've had warranty repairs commuting 10-12 miles each way with a backpack and with panniers (Arkel commuter with a suspended laptop pouch). With no reliability difference the pannier is much more pleasant.
Good solutions are :
- A thumb drive with your files
- A virtual machine on a solid state drive you use at home and work
- An on-site service contract so they repair your laptop while you wait
- Sub $400 (assuming you don't need high resolution) laptops you replace after a failure
The pannier picks up more dirty water when it's raining, although a rain cover keeps that off so I can separate the gross stuff from my bag and contents.

I only put 15-20 pounds in my single left side pannier, although at that weight track standing doesn't feel any different from an unladen state. Handling is unaffected. Riding out of the saddle does feel very different.

Given a rack with side frames, panniers with a solid bike side sheet, and solid attachment mechanical interference is impossible unless something breaks (like a rack weld).

Who says? You definitively know that this contributed to your failure and that one can expect reliability problems by carrying a laptop in panniers? Data please.
You cannot draw these conclusions from a single incident. My last laptop went around the world 17 times and never failed and got heavily abused. That also doesn't say anything about reliability.
There are so many other variables that contribute to reliability - exposure to humidity, temp cycling, vibration (frequency matters and varies), vibration during temp cycling (actually worse that either temp cycling or vibration by itself), over voltage stress, etc... There is simply no way to say if this "vibration" received in a suspended pannier is even worse that what it might get in other applications without data and testing of a number of units. Sample size of one is irrelevant.
