A tangle bag makes use of the unused space in the main triangle of your bike frame. It's a great place to keep a flat repair kit, sunglasses or your wallet and keys. I will show you how to make one like the one I made for a friend.


I used a medium weight cotton canvas, it's about $11 per yard and I used less than half a yard.

A zipper, the one I used was water resistant and 30" long.

2" wide Velcro, about 18" of it.

White micro-crystalline wax similar to this, purchased at local art supply store. Beeswax or Paraffin would also probably work fine.


Sewing tools(sewing machine, scissors, etc.)

Heat gun, for melting the wax. $15 at Harbor Freight.

Disposable bristle brush, for applying wax.

A heat resistant bowl you won't mind ruining, for melting the wax.

A putty knife or butter knife, for working with the wax.

Step 1: Make a Pattern

First decide how big you want the bag to be and cut some cardboard to the height you want.

Then mark the angle of the front and back, make sure you mark which way is front.

You should also mark where any cable fixtures are so you don't put the velcro straps there.
<p>This is a great instructable, but being 14 years old, I dont have the skill to do this. There is a bike shop near where I live and they are haveing a sale on large seat bags, so how easy do you think it would be to convert one into a frame bag? It mesures to the correct size of my frame, and with a dropper seat post on my bike, I can not add a seat bag.</p>

Love the waxing instructions! Looks like fun to do as well.
great instructable and actually useful!
Why did you say not to get wax on the zipper? Wax is one of the best things going for maintaining zippers. The Army issues crayon-looking wax sticks for the Humvee soft door zippered windows, and it works like a charm for my jeans too.
Fantastico! Love it
I love the length of your tangle bag, but why use wax and not just buy waterproof fabric?
Thanks! You could definitely make it with some coated cordura or x-pac and it would be just as waterproof. You would probably want to seal the seams with tape or seam grip, whereas the wax impregnates the fabric and the seams and the threads all in one step. Plus I like the look of the waxed canvas and I had been meaning to try the method out!
I gotta say this is one of the first Instructables I'll actually be making. I could use something like this for holding spare/bike repair tools.
That wax would melt into the fabric all by itself if I left it on the back patio today.
