What's the best way to transport groceries on rough roads without breakage? (My town has a generous budget for potholes.) I currently use a 2-wheeled cargo trailer, but it there anything I can do to cushion the more delicate items (i.e., eggs)? What about items like milk, where every pothole causes the liquid to slosh around?

I remember seeing a horrible movie where they were transporting a volatile chemical by semi, and they suspended it in the air in the back of the truck with rubber cords/cables. –  Jared Harley Aug 29 '10 at 16:29
    
That looks like a pretty nice two wheeler. How do you like it? Does the mounting work well? The mounting on my two wheel bike trailer often swings in and hits my rear bike wheel. –  sixtyfootersdude May 16 '12 at 2:53
    
@sixtyfootersdude - The mounting is sturdy, as is the trailer. However, the hitch mechanism can get stuck from time to time; loosening the hitch's axle and rotating it back to vertical takes care of that. No issues with the hitch hitting the rear wheel while riding. –  Neil Fein May 16 '12 at 15:24

Delicate items would probably survive best in a small backpack. Your body acts like a natural shock absorber so anything strapped to your back should get the smoothest ride, especially if you're out of the saddle for the bumpiest sections. Remember to keep the pack light though.

Put heavier items like milk on a rear rack, rear panniers or ideally on a trailer. On your back they can get really tiring and on a front rack they can really destabilize your front wheel (even worse for something that sloshes around).

Fragile and heavy? (e.g. jars, glass bottles) Put them in a carrier on the rear rack, but make sure they're well padded from both the bike and each other.

How do you feel about modifying your trailer?

  • adding some suspension could absorb some of the bumps
  • bigger wheels and high profile (i.e. lots of rubber) low pressure tyres would also go a long way towards smoothing out bumps in the road, though a warning: if they're too wide they might reduce your manoeuvrability with the trailer attached
  • some permanent padding for your trailer (and maybe a waterproof cover to keep said padding dry if you don't already use one)

Otherwise maybe just a padded bag for the delicate items (and if there's only a few, definitely stick it on your back as darkcanuck suggests for maximum suspension).

I might be able to get bigger tires for the trailer's 16" wheels, that's not a bad idea. –  Neil Fein Aug 30 '10 at 19:18
    
Burley replied to me with this CYA email: "We have not tested the Nomad to accommodate wider tires so we cannot guarantee structural integrity or safety with any modifications." –  Neil Fein Sep 1 '10 at 1:31
    
as an engineer (in australia) it makes sense to put it this way from an ethical/legal point of view - if you're not completely sure, you don't dish out engineering advice. otherwise someone can sue you if you're wrong, so equally, I'd say the same, especially having not even seen the trailer or done any kind of analysis on wheel sizes/widths/... but... –  drfrogsplat Sep 2 '10 at 3:31
    
... unless this thing is an especially light frame or there's little space around the wheels, then it'd probably be fine. if you have any friends/family with a mechanical engineering degree or mechanics who do any custom frame design/modification/etc, ask them for some advice, and how sure they are about it one way or the other (and don't sue them if they're wrong if you've only asked them for some quick/free advice!) –  drfrogsplat Sep 2 '10 at 3:34

I don't transport a lot of groceries, but physics tells us that we really shouldn't worry about going up and down so much, but that we should worry more about things getting knocked around. An egg in the carton shouldn't break simply because you accelerate it quickly, it's going to get broken when it takes flight and then falls back down. Uneven pressure is the problem here. Remember, the back of a truck probably isn't any smooter of a ride than your bicycle. You should make sure that your groceries are tightly packed, so that they can't move around so much, and maybe even use bungy cords with a nice soft foam on top and on the bottom to ensure they don't bounce up and down when you do hit a pot hole.

I chose darkcanuck's as the best overall answer, but this makes an excellent point. +1! –  Neil Fein Aug 29 '10 at 17:48

Something like the Bob trailer could be useful. It has suspension.

The BoB trailer is a one wheeled trailer so probably modifying yours to work like the Bob would be impossible. However if you were to build a new one making something like the bob could be a good idea.

My understanding is that one wheel trailers are better for rough conditions.

Edit: The other benefit may be that you can weave around potholes more easily. I have a two wheeled trailer right now too but it is tricky to avoid potholes with three wheels at different spots on the road. This may be easier with a single wheel trailer that tracks directly behind your bike.

Unfortunately, replacing my trailer isn't something I can afford right now, but I've had my eye on the Bob suspension trailer for some time-- it looks like a sweet piece o' gear. –  Neil Fein Aug 29 '10 at 20:49

I've had experience transporting a laptop, which I also didn't want to jostled. The best padding for it was not an official "laptop sleeve", but wrapping it in bulking fleece jacket, and then stuffing that into my pannier, which made a tight fit. I would be inclined to take the same approach with a carton of eggs: wrap them in fleece jacket, stuff that in a container, and strap it tightly to the trailer.

Also, let a little air out of the trailer tires for some free shock absorption. ( I used that trick today when taking my 3 month old on his first bike ride, in a rear-facing car seat strapped into a bakfiets ).
