Picture of Bike Mudflaps
I needed mudflaps and fenders for my commuter bike (I live in the GREAT North West!!) so I went looking for ideas to start the creative process. I realized there is an emptiness here when trying to find 'ables about mudflaps, no mudflap love.

So I took it upon myself to start the mudflap revolution. No more will I have to put up with muddy toes and shins while pedaling to school or the grocery store. Nor will you!!

I had a plethora of PBR cans around and decided to use them. Re-use!!

It actually only took one can though.

What you'll need:

One empty 16oz beer can (I already had this, you might have to drink to create an empty)

razor blade and or tinsnips

Gorilla glue, or JB weld (to attach to fenders, rivets protrude and can be a flat hazard)

Gloves (to protect your delicate fingers)


about 30 minutes of spare time

Step 1: Decide what statement your mudflap is going to make

You will need to have an empty beer can, or soda can for the sub-21 crowd. You may use a can already in your possession or empty one just for this occasion.


Consumption of too many beers prior to the following steps  may increase the possibility of injury.

I chose PBR, but any beer you feel represents who you are will do.

Step 2: Size, shape and cut

You need to decide how big your mudflap will be, and go bigger by a half inch or so on all dimensions as you will be folding over approximately 1/4" on every side.

I found it easiest to freehand this, but you may want to draw your shape with sharpie.

You can pierce the can very easily with the razor blade and use a rocking motion to cut a straight line (picture the razor blade as one half of a scissors. (or is it scissor?)

You want to get some of the tapered bit at the top (just below the rim) as it will help keep a nice curve in the finished product once folded over.

Silicone? Might last longer and be a more durable adhesive.

Nice project. IMO, fenders are for the rider while mudflaps are for the folks behind you. I believe that's why mudflaps are popular with touring.

Good 'ible, but there's one thing I don't get. Why should people have to add mudflaps to fenders? Why the h377on't they just make the fenders long enough in the first place? Pfffft.

I don't get that either. Most mountain bike fenders come with a flared end, as though mud is the only thing that gets all over my shins and feet.

My fenders were short too, so I added some mudguards made out of empty aluminium cans, they don't last long but their are virtually inexpensive and easy to replace.
