This is a quick hack I just thought of to make a rear mudguard for the rainy season. It should be noted that this setup may be only suitable for those with a unused rear brake bridge like those cycling fixed gear bikes or those with disc brakes. The reason for this is that the guard is mounted on the rear break bridge. Some fixed gear cyclists remove the back brake as back peddling and locking the back wheel is adequate to stop the bike and some disc brake fitted frames have a drilled rear brake bridge.
The mudguard is manufactured from household tools and spare parts lying around and takes about 30 minutes to make and fit. The main structure is from an old scrap aluminum bike wheel. Since this is essentially a bike part it somehow looks okay and works well as a mudguard.
Step 1: Get Your Kit Together
To make the guard you will need the following:
1. A glue gun and a glue stick.
2. A hacksaw.
3. A scrap bike wheel (I used a battered aluminum wheel, measuring 622x17x6106, The larger the diameter of the wheel the better as you want it to curve around your wheel. Adjust the size of your jubilee clip accordingly.)
4. A jubilee clip (i used a 12-20mm clip but the size of the girth of your scrap wheel will dictate which size you should use.You want the clip to be a tight fit.)
5. A metal file.
6. A spoke and nipple.
7. A piece of string around 330mm long.
8. A M6 bolt 40-50mm long.
9. 6 x M6 nuts.
10. A bendable sheet of tough plastic roughly 300mm by 40mm. (I had a small sheet of transparent thick vinyl lying round but you could easily use thick plastic from a bottle or other container)
