Introduction: $1 MTB Mud Guard

Picture of $1 MTB Mud Guard

This is a super cheap way to have an indestructible mud guard on your mountain bike.

Things you will need:
Cheap plastic cutting mat ($1 at Dollar Tree)
(4) zip-ties

Printer (to print out stencil 8.5 x 11)
X-acto knife or hole punch

Step 1:

Print out stencil PDF  on 8.5 x 11 (landscape) letter paper and cut it out with scissors. Don't forget to cut out zip tie holes.

I added a second version of the mud guard. I extended the guard past the forks to control even more of the muck and mire. Enjoy.

You will need to print out both pages line them up and tape them together and then cut out the whole stencil. (I did this because I figure most people only have letter size paper not 11x17 or the like.)

Step 2:

Step 4:

Mount mud guard onto forks. Loosely attach all four zip-ties to fork. Stating with the top zip-ties snug them up to the cross member making sure the mud guard is centered. Then snug the zip-ties on the down tubes. Then snip off zip-tie tail.

Step 5:

The pattern is great. Photos show the clearance is totally adequate. When used as a rear mud guard, the mud/grim protection for the pivots is exceptional. Note the lack of mud on the linkage. Tip and tail pattern can easily be modified to personal liking/needs but it's the starting template that really saves time here. When used as a front mud guard, the part in front of the arch can be extended but I load mine into a Thule T2 with front wheel arm trap and the fender would get in the way if I used the longer template. I've had fun hitting the dollar store and others to find cheap cutting mats of varying colors and thicknesses. Great gift idea also! Your buddies will tease you but then when they have to clean less off their bikes they will be loving you. Mounting hole pattern can easily be modified to your specific frame design to maximize clearance. Holes can be replaced with tiny slits from a utility knife if you lack a way to make the holes. Thanks jdlee77!

Justinv12 (author)2016-05-27

What size should the final product be? Length and width? of the front and back?

jdlee77 (author)Justinv122016-05-27

The "small" one prints on 8.5" x 11" paper. So it's approximately 8.5" x 10". You can use the same pattern for the front wheel and back wheel on your bike. Happy Building! Dont forget to come back and post photos!

Justinv12 (author)jdlee772016-05-29

Thanks. I tried it out this weekend. Came out perfectly. Just need to get on some wet and muddy trails!

Very Clever! so simple yet so effective.

Love this project! I'm taking her out tomorrow for some trail action and it rained today so we'll see how well the guards hold up. I used the smaller guard for both front and rear, but in the future will make the center holes closer towards the center for a rear guard as the pivot on the rear triangle is narrower than the holes on the template.

Awesome template. Used for front and rear guard on two different bikes (29er and 650B.)
