Start by using super glue to attach 3 mounting squares to the back of your watermelon sign.
While your glue is drying make your bow. Grab your EZ Bow Maker and one of the 2.5" ribbons. Make an 8" tail, twist the ribbon and add it to your bow maker. Then make a 6" loop, twist the ribbon and add that to your bow maker. Repeat with another loop on the other side. Then cut a shorter tail and pull your long tail towards the bottom and your short tail towards the top.
Repeat this same process with a 1.5" ribbon just make the loops a little smaller this time. Repeat again with the next 1.5" ribbon.
Now use the 4" ribbon to make two more tails and two more loops. Then use the window pane or mesh 2.5" ribbon and repeat for your last main layer.
Next use your last 1.5" ribbon to make a small loop and 2 tails, this will be the center of your ribbon.
Finally, take two pipe cleaners and twist the ends together to make one long pipe cleaner. Remove your bow from the bow maker and use the long pipe cleaner to secure the center of the bow twisting it off at the back.
Next, use zip ties to attach your sign to your bike wheel. Use wire cutters to trim off the ends of the zip ties.
Now take your greenery stem and full it out, use zip ties to attach it to the bike wheel. Then do the same thing with your red flowers.
Attach your bow, using it's pipe cleaners, right on top of the greenery and flowers.
Next, cut about a 14"" ribbon tail of each of the ribbons you used in your bow. Use a zip tie to secure one end of the tails together and then add that in right under your bow using another zip tie. Dovetail the ends of your bow and your ribbon tails.
