Yesterday, as I was heading to campus to take care of some business I spotted a couple of Thai students struggling with carrying a futon's frame.

I thought for a second, and offered to help them. One end of the futon was balanced on the rear rack, and they held up the other end. We crossed the street (towards the dorm), where another student was carrying more of the futon, so we loaded up that, and she joined in helping stabilizing the load. Half a block later, there were a couple of really big guys helping them carry the futon's mattress, so we made a little parade carrying the bed to their new digs.

Turned out, they weren't going to the dorm a block away, they were moving into an apartment about 5 blocks away. In the end, the bed was delivered to their doorstep, and I made a bunch of foreign students very happy. (Too bad I didn't take a picture those gals were cute )

That was the largest (single) item I've carried on my bike. What's yours?

Probably a weedwhacker

Ha, just my backpack for now. My rack has a max weight limit of 20 pounds.

Well that would be my 300+ pound body when I started riding... Now it is a couple of panniers of groceries...

Another bike in its shipping box might be the biggest single item. I have carried 6 bags of mulch before that was wetter than it should have been, which was probably the heaviest load. I have ridden my wife and two children on the bike numerous times. I'm talking about my Yuba Mundo though which is made to do this kind of stuff.

Volume-wise, a Little Tikes play kitchen in the box, for the 4 miles from Toys R Us to my house.
Weight-wise, the heaviest I have measured yet is 42lb of commute supplies and groceries.

I can't vouch for the exact weight of the groceries, but last week I hauled groceries, and 2x26lb (each) watermelons... "I'll have that quadruple bagged please..."

apollored

Either six heavy plastic bags of groceries, 3 to each handlebar or three king size bedsheets in my rucksack plus two pillowcases wet from washing and very heavy, tho they were only carried half a mile or so.

I hadn't thought about weight; I have pulled a trailer past 100# of kids and groceries. Trailer's capacity said 100# and it was ... right, the frame definitely sagged after a few of those kinds of loads. 40-50# of groceries in panniers not atypical.

Planet Earth. When I flip my bike over, the entire planet rests nicely on the handlebars and saddle.

I once towed both my daughters plus luggage to their day camp. They were officially too big for the trailer, but I had left my car at the garage for repair. I think the total was about 180 pounds. It wasn't too bad.

I often tow 60 or so pounds, perhaps sometimes over 100.

The largest thing I've towed is probably my bike repair stand. Then again, I've towed two bicycles, so that's a bigger bundle.

Used to get a lot of stares when I carried my outrigger paddle in a backpack riding to the boathouse.

Back in college I went shopping on a whim / bought beanbag chair, laundry hamper, pillow, and various household goods.
Paid then went out to the parking lot and couldn't see my car ... Forgot that I had ridden my bicycle.

So I put the pillow and the small stuff in the laundry hamper and held with one arm, grabbed the beanbag chair with the other, then rode my 10-speed road bike back to my apartment.
Fortunately it was only about 1-1/2 miles away and no traffic. I was able to marginally maneuver the handlebars with the hand holding the beanbag but most of the ride was hands-free / no brakes.

Another day I rode my bike to the LBS and bought a new bike. I rode home with the new bike rolling alongside and I had one hand on each bike's handlebars. Both were nice 10-speed road bikes.

Many years later I attempted to take my cat to the vet with the large cat carrier roped onto the flimsy rear rack. It wasn't a stable platform for such a large cage and it kept slipping off. Not good for me, bike, nor cat. Vet gave me a lecture.

250 college essay answer tests. The panniers were full to bursting and I popped a spoke on a 36 spoke 3 speed wheel with equal dishing.

Woah...

Mine is similar - eight teacher edition textbooks (two books per class) would take the cake for weight. Probably 10ish lbs each. Awkwardness would be two 10ft 2X4's and four 10 ft 1X1's.

another bike

I welded some bike parking for my house, something like this, but steel, with room for four bikes. It was about 8 foot by three foot. It came to the welding studio on my bike, albeit in pieces. When it was all assembled, I realized just how huge it was. I can't say I carried it, wore it would be more appropriate. One side rested on my front rack, the other on my rear rack, and I was awkwardly leaning in the middle.

I did make it home though.

A table and a trail a bike in one load was the largest probably.

The heaviest was the co-worker you can see on the blue bike when he needed a ride to the shop so he could pedal his new bike home.

nashvillwill

A 50 lb bag of dog food. Combined with the 15 or so lbs I already had in the trunk bag (and the 200 lb operator) I think it was slightly over my racks weight limit.

Sharing the load between a trailer and a sidecar, I hauled 7 cases of wine, totaling about 245lbs. Did OK, but I've tried to keep it less, because it was a lot of work!

JAG410

I carried a foosball table on my Xtracycle earlier this year. Not the heaviest but probably the biggest thing I've carried.

KonAaron Snake 

An air conditioner was the heaviest...possibly biggest as well.

Ekdog

We're in the midst of moving. Just hauled this cabinet a couple of kms.

Seven cases of vino... That must've been some party!
