Introduction: DIY 0$ Bike Fender

Picture of DIY 0$ Bike Fender

Hello!! It's my 1st instructable.
Every part and tool for this instructable I've found at home. That's why it cost 0$. 

Step 1: Materials & Tools

Step 2: Cutting the Parts

After you cut the parts make the borders flat and equal.

Step 3: Repair the Broken Fastening

Close the cap strong as possible as you can and mark places for holes.
Make two holes in the cap and tighten to broken fastening.
Then attach with glue or something else to make it reliable. Maybe Sugru is the best way.

Step 4:

My main part of fender is to short so I decided to make it longer.
You may use a Crop-a-dile or anything else to connect the parts .
Connecting the parts avoid curvature relative to each other.

Step 5: Enjoy

Fender width is 10 cm. It's wide and I like it!!!
Enjoy!!
Next time I'll show you my 0$ bike bottle holder. Hope It wil be soon.

Please leave comments and suggestions.
Please watch the video to see the fender at different angles.http://youtu.be/QZCIGrlptJM

Brillant ! Clever, and looks quite cool with that.

Your bike has suspension - it might have been better to mount the mudguard/fender to the rear triangle, not the seat post.

If you can make it longer both forward and backward that will help a lot. I have an "ass saver" which is at seat height, and it does NOTHING to protect my legs.

Ingenious idea. Commercial vendors are so proud of their products and they love shipping and handling charges.

Thanks so much for this instructable.

Thank you so much for this instructable.. I followed through and I improvised a little. Instead of using the clip and go through the gluing stage, I used a used tape "plastic part" which fits good on. Making it easy on easy off.

I extended it too using some Allen key bolts and screwed it with butterfly screws down below which in turn makes it easy to add or remove the extension.

Sprayed it and added one sticker that I got with my GoPro. I think I will add some more!

Thanks again.. You made my life easy! Trek stuff ain't cheap!!! :)

Great idea and re"cycling" :-)

vladeta.pajovic (author)2015-03-29

This is great job, any idea for front fender?

brids78 (author)2014-09-19

You could you a heat gun to bend a curve in the plastic. I really like this idea! I'm going to make one for my bike. Thanks for the idea!

jims212 (author)2013-09-16

Very Cool. I want to make one too, but with the hole facing the rear of the bike for a tail light. It seems some LEDs and a 9 volt battery would fit in there real nice and covered with a red plastic lens. Thank You

It occurred to me that a light could be attached to the top of the fender. It might bounce around a bit, but it would be a cushioned bounce, and it might add to the attention-getting capability of the light.

gpavlovsky (author)2013-09-17

Looks pretty nice, almost like factory-made, except the extension part not blending in with the rest.
Most of the materials are readily available, but a spare seatpost clamp (part of your old fender) might be not so easy to find. I guess one could use a U-bolt or a band clamp instead, those wouldn't look so nice though.

bo88y (author)gpavlovsky2013-10-13

Lots of cyclists have brackets that were once mated to lights that have been lost or broken. Ask around.

wellming (author)2013-10-02

It's a good way to recycling use of waste resourses

darrenhall (author)2013-10-01

Hi - well I have seen some home made bike fenders - some trashy and some ok - this build is beautiful, good as shop bought.
Great job, really excellent.

looks extremely professional

dwebb5 (author)2013-09-24

Excellent!
Dirt Cheap, lightweight, and because you connected it through the cap: Replaceable!

pvoss1 (author)2013-09-24

Definitely more straightforward than cutting a piece of PVC pipe in half lengthwise, although possibly not as rugged. What brand for this specific jug?

StasinG (author)pvoss12013-09-24

It's an antifreeze jug.

Lectric Wizard (author)2013-09-18

GREAT IDEA !!!

diamondemb (author)2013-09-18

Love this idea. Great job!

iOskr (author)2013-09-17

Great idea. Thanks for sharing!!!

quickie817 (author)2013-09-16

very nice looking. Looks rugged, Now I gotta go find me a black bottle!!!! Some people ask for more details but I think your instructable is fine the way it is. It is like a general blueprint that encouraged us to use our imagination. Besides, I don't think it needs to be specific because not everyone will have the same materials. I think those that are asking for specifics just don't have much of an imagination or ingenuity.

2hammers2 (author)2013-09-16

nicely done.

darrennie (author)2013-09-16

Great Ible project to start the week.
No pressure but a front fender would complete the set.
Love the idea.

bricobart (author)2013-09-16

This I'ble's just in time since I need a new one, oh man this is awesome!!!

tjk1939 (author)2013-09-16

Now that is creative. Inexpensive too. Nice job, you gave a great mind.

antioch (author)2013-09-15

Awesome, but a few things are unclear. Like this one: https://www.instructables.com/file/F4T37VMHLID3BVH
What is it?

StasinG (author)antioch2013-09-16

it's a broken fender clamp. I mean the clamp and the fender was one detail. But fender was lost.

antioch (author)StasinG2013-09-16

Ahahaha, so that's why it looked somehow familiar to me. Well, thanks!

maxman (author)2013-09-16

Excellent idea. Thank you.

aylbegi (author)2013-09-16

Idea's like yours are the reason of this website.
Just perfect.

michaelmacnz (author)2013-09-16

Good ible and well done thinking outside the square..

FrankBlourtango (author)2013-09-15

Dude. That is so awesome. Who thinks up cutting up an antifreeze bottle and making a bike fender out of it? You have renewed my faith in humanity.

StasinG (author)FrankBlourtango2013-09-16

:)) You know, the antifreeze bottle with out cut parts still usefull. And I'm going to show how I use it in one more instructable soon. I saved the world from one plastic bottle!!!!!

dropkick (author)2013-09-15

I will always remember riding my 10-speed (with no rear fender) down an oiled dirt road to meet up with my parents when I was a kid.
My Mom's first words when I got there were "What did you do to your new shirt?"
I've never had a bike without fenders since.
Good job.

thirst4know (author)2013-09-15

Haha This is correcto! Gear heads would drop a c-note for a name brand fender. Nice work. I was thinking of using a thin walled pvc "strip" heat curved fenders for my e-bike I am testing now. Maybe some core-vent fairings too?

thirst4know (author)thirst4know2013-09-15

Also I just made a coffee cup holder for my handlebars. 4" or so stainless steel hose clamp and a 2" one to hold the 4" to the handlebars. Works great and is adjustable.

iakirov (author)2013-09-15

Very cool, nice looking fender. I'm already thinking on making one like this.

qcidiana (author)2013-09-15

Very clever...

instructabowles (author)2013-09-15

Dude, this is the first 'ible I've ever felt moved to comment about! Truly functional and cheap for something that always get thrashed and needs replacement at $. Super cool; Not cheesy and thinking way outside the bottle i.e. box!

moebuspcgold (author)2013-09-15

@StasinG I like your instructable! The colour of the plastic looks like the real thing. Very good work, keep it up!

f5mando (author)2013-09-15

Spot on, that is! Well done, and thanks!

rippa700 (author)2013-09-15

Great! I love it and am going to copy it. We have a rubbish store-bought one that flaps about. Yours is what I like - upcycled 'waste' and it looks very cool. Well done - good thinking and good 'ible.

rimar2000 (author)2013-09-15

Very clever, it seems fashioned and factory made.

Dark Passenger (author)2013-09-15

excellent. So simple.
great example of up-cycling

chuggins143 (author)2013-09-15

Pretty slick! Good job! :)
