Usually mountain bike fenders, particularly on suspended forks, are connected to the steering tube of the frame. They're one or two plastic pieces, more tough at the connection side, to resist at a good flexible force.
In this instructable you'll see how much easy is to build your own bike fender with reused plastic stuff. This is not only fun and cheap, but it also will convert at once a garbage into a plastic gadget ready to use, and this is the best way to recycle.

Step 1: The Garbage

You can have a different liquid soap container, but usually they have almost the same shape. Maybe you'll be very lucky and your bottle will be better than mine! Plastic on these bottles is more thick on the bottom part, and this is very handy for us, because it means the fender will be though in the right side.
Cut the rounded part with the scissors and refine the border with a cutter, beware to not cut yourself! You'll obtain a boat shape, leave some plastic on the corners of the back sides, so that they will help to reinforce the connection with the frame.
I have a pair of the same breaks... good right?
A little spray paint would finish this up nicely, and give it more of a pro look! <br>I think it'd be quite nifty in a flat black. <br>Neat idea!
yes, of course! Since the shape reminds exactly a fender, a better color will certainly gives a pro look, I only was worried about paint durability...
Motorcycle fenders often are just painted plastic.<br>I think Tremclad makes spray paints specifically for plastics like patio furniture.
Krylon makes some too.
is there an easy way to get the cut out from the bottle perfectly measured on both sides?
I'm not sure, but I would try with paper duct-tape, actually my cuts are not 100% precise, but it's hard to see...
Love the Super V and your Maguras!!! Good 'ible too!
Great idea! I hate it when I ride through a puddle and my legs get soaked. This should help solve that problem.
Thanks rimar!
I suggest you put as first image of the instructable the photo 1 of step 5, where you show the rear part of the fender, that is the really useful.
Yes, I agree with you, as I wrote in last step I've decided to put that image first because I thought it was better to see, but it seems I was wrong. I try to change as you say, let's see if more visitors will come...
