Any suggestions for a bungee net of some sort to attach a backpack to a rear rack? The backpack is significantly wider than the rear rack, which is this one here

I don't recommend a bungee net for a large backpack, unless you find one with really thick cords that you can pull tight. I've used a lightweight one which worked fine for a bag with small light loads. Anything bulkier or heavier risked flopping over to one side.

The real advantage to bungee cargo nets is in having a lot of straps, which lets you loosely strap something down and it won't easily slide out. It's convenient, secure within its limits. A big bag, or laptop bag for example, that needs to be strapped tightly by strong cords defeats the purpose.

Buy panniers instead?

The backpack in question something about this size:

I'm also looking for a similar solution for my wife, so she can carry a large purse or messenger style bag.

I haven't come with a good way of attaching a backpack to the rear rack. Thought about going with a large pannier, but I think that would just add extra weight be too bulky, and cause the weight to shift to one side.

Any suggestions?

Bungee cords, but not a net.

This is what I do:

Is it secure? Here's a video of the same setup a few years ago with my old backpack minus the D-Clips!

Seen Done

attach a dowel of wood, like a broom handle, across the back of the saddle , that is where you secure the shoulder straps of your Back pack \

With its bottom supported by the rack ,..

It works even better with small wheel folding bikes because the rack over the rear wheel is Lower

so the back pack is secured Higher on it's mass..

Clever!

This isn't what you asked, but I have this product on order: https://www.twowheelgear.com/product...ck-convertible.

It's a backpack that also functions as a pannier. It should arrive on Tuesday.

BikeLite

Have thought about it. I would try attaching something flat and strong to the rack to give it a wider platform and then attach the pack to both.

Lone peak sells their pannier hardware which you could have sewn into your bag, or maybe attach through grommets.
Pannier hooks
You could use the bungee with s-hook for the lower attachment.
Pannier Bungee Set

I think you can buy similar hardware from Ortieb
Check with bikebagshop, and thetouringstore
Wayne at the latter is a really good guy - swap some e-mails with him.

We have the Lone Peak convertible back pack around here - I think they discontinued it and we bought it on closeout.

sits kind of high and is neigher a good pannier nor a good backpack.


If you have a big pack, on that little rack you're going to find yourself kicking it every pedal stroke.
Tubus and Nitto both make big rear racks that sit farther back to give you good clearance, and have lower mounting rails to help keep the weight low.



this Racktime rack is made by Tubus and is a steal at under $40.

I use my snap in large rear basket on my Rack Time rack and put my 55litre backpack in there.


Very secure.

This works well for me, with a wide backpack.

When I was a student a long time ago, I used a couple of spring snap clips on my back pack to quickly clip it to the rack while it hung on the side similar to what fredrico above did. Couple of carabiners would work too but the spring clips were a bit cleaner and easier to use.

My solution to the OP's problem back in the day was to mount a beverage crate to the rack, place bag on, then use a bungee (or 2) to ensure it didn't wander too far in case of the bike falling over. It was like having a pick up truck bed on my bike . I was able to put my bag on it whenever I needed to root around for gloves or whatnot and not worry about placing it on the ground. Downside was that it was stable in a straight line, but any aggressive handling situations got dicey.

The pics I had of the set up were deleted off the server at some point and I'm having a hard time finding an example, but basically envision a milk crate that is rectangular and the sides have been cut down some what. I actually tried a milk crate before, but a) my posterior was rubbing the top of the crate while riding and b) my backpack was too big when it was fully stuffed to fit.

My setup in the 70's: I strapped a milk crate to my rack. It was tall enough that when I tossed my bag in, I didn't need any straps.

Basket? Wald, and others, makes baskets that you can zip tie to your rack, and would securely hold your backpack or wife's purse. Others suggested a milk crate, which would work too. I've seen people use square buckets too, just bolted to the side of the rack like a pannier. Keep in mind everything you attach to your bike is gonna impact handling and efficiency.

Bulldog1935,

What is the rolled up army-green item in the picture? I'm looking for a low profile "pannier-on-demand" in case I buy something on a ride that I didn't expect to carry home. This might be what I'm looking for and didn't know it existed.

Thanks,

This is the way to do it. (I thought you were talking about a 6,000 c.i. expedition pack.) The Osprey Escapist is under 2,000. Bungee it as tightly as your strength will allow and then tie it down with natural fiber rope.

bulldog1935

hi friend, it's actually not a roll at all - it's a Randi Jo MUT bag carrying an extra 25 oz thermos of cold water

Brooks, Linus, and a few others make roll-up panniers.
There are also some trunk bags with expandable panniers built in.

I'd second the bungee. That's what I do. Maybe even 2. And wrap through the straps to keep it more secure.

Now I have a porteur rack so I just put my backpack on the front and use my cargo net. Same with the purses.

I did do various bungee configurations with my purses but honestly I felt like that would jack up the shape. I'd get a basket for the wife's purse. Especially if she wants them to keep their shape and she uses structured ones. Now my cargo net and front rack is a flexible platform for all my purses.
