Repairing a cracked plastic fender on a bike is a relatively easy task. First, you will need to remove the damaged fender from the bike.

Cut Patches

Cutting patches is an important step in repairing a cracked plastic fender on a bike. To begin, you will need to cut two pieces of fabric or plastic that are slightly bigger than the size of the crack. Make sure you use a sharp cutting tool to ensure a clean cut. Once you have cut the patches, you can place them over the crack and secure them with tape or glue.

It is important to ensure that the patches are seated firmly in order to ensure a tight seal. Whatever material you use, make sure that it is waterproof and resistant to heat and chemicals. That way, you can be sure that your repair will last for a long time.

Apply Patches

Applying patches to a cracked plastic fender on a bike is a relatively simple task. To start, clean the cracked area with a damp cloth and remove any dirt and debris. Once the area is thoroughly cleaned, cut a patch that is slightly larger than the cracked area. Apply a thin layer of adhesive to the back of the patch and the cracked area.

Line up the patch over the cracked area and press firmly to ensure a tight seal. Allow the adhesive to dry for the recommended amount of time, as indicated by the manufacturer. Once the adhesive is set, you can use a paint marker to color in the edges to hide the patch and give the bike a finished look.

Secure Patches

To secure the patch to the bike’s fender, you should use an adhesive that is designed specifically for plastic. This will ensure that the patch is held firmly in place. Additionally, you should make sure that you clean the surface of the fender thoroughly before applying the adhesive.

This will help to ensure that the patch is properly bonded to the fender and will remain secure. Once the adhesive is applied, you should press the patch firmly onto the fender and hold it for several seconds. After this, you should allow the adhesive to dry before continuing to work on the fender.

Reinforce Edges

Once the plastic fender is in place, you will need to reinforce the edges to prevent further cracking. To do this, use a hot glue gun to apply a bead of glue along the edges of the fender. Make sure to apply the glue evenly and work it into any cracks.

If you have any gaps, use a sheet of sandpaper to gently sand down the edges to make them smooth. Once the glue has set, you can apply any type of sealant to further protect the plastic. This will help keep the fender from cracking again in the future.
