Wooden Mudguard Mounts/eyelets

This is a very simple construction that will enable you to mount mudguards/fenders or racks to any bicycle that doesn't have eyelets for screws.

Step 1: Materials/Tools

10mm Ply wood

Cable ties

Varnish/epoxy/paint/PVA

Hole cutter bit 20mm

Small drill bits

Hand saw

Sand paper

Step 2: Process

Cut hole with hole cutter bit. Use the "waste" circle, discard the hole.

Saw into two semi-circles.

Drill two small holes in each for cable ties.

Drill holes for fender screws. Take care to make these smaller than the screws so that the screw thread can bite. If the screw is tight, there will be no need for a bolt.

A nice touch is to file a concave profile on the flat edge of the semi-circle. This can help the mounts seat on the bike forks or seat stays. I have tried rubber shims, cut from inner tubes, to seat these mounts but they will sit perfectly well without. Just ensure the cable ties are tight.

Sand and varnish to waterproof and finish. Epoxy or even diluted PVA will work too. You could of course paint to match the bike but then people might miss your genius.

Nice idea!

During winter when it's often raining or snowing I also install mudgards with similar eyelets on my racing bicycle, but I use a simplier layout. I just wrap one or two layers of inner tube rubber on the frame and put a plastic wrap on the eyelet (where the screw should be). I take care to put the aluminium mounting a little aside of the tubes to have some "flat" surface in common, the rubber friction is enough to provide good stability. For the front fork I use complete sections of inner tube that I slip on each stem, for the other part of the frame I just wrap the layers of rubber and bind everything with an external wrap of tape. I also use plastic wraps to fasten the front mudgard on the top of the fork, having drilled two buttonholes of the size of the plastic wrap on the mudgard. I recycled these mudgards from a tourist bycycle so I had to remove their upper brackets becasue they didn't match my frame geometry and clearance between the wheels and the frame.With plastic wraps and buttonholes on the mudgard I was able to install them easily. I also installed side wings of a plastic sheet to protect the area behind bottom bracket, from above the tangent of the wheel to the seat tube and there chain stays. This protects feets from water bounces on the tube.

Awesome simple design. I could see them maybe made from aluminum or plastic so as to be more weatherproof. Depends on what you have around.

Good idea. I'll try with with some perspex/acrylic. It should work with same tools. There are alternative designs that would suit aluminium like this example which is doubtless mild steel: https://www.instructables.com/id/DIY-dropouts-for-b...
