DIY Bike Clock

Calling all cyclists–keep up the RAGBRAI spirit year round with this do-it-yourself bike clock! Full instructions below.

Supplies:

  • Bike rim
  • Metal house numbers (we used 1, 2, 3, 6, and 9)
  • Spray paint in color of your choice
  • Super glue
  • Clock kit
    • Minute hand
    • Hour hand
    • Square battery piece
    • Rubber gasket
    • Brass washer
    • Mounting nut
    • Open nut
    • Appropriate battery
  • Metal sprocket or other decoration (optional)

Steps:

  1. Gather your materials. If you’re having trouble finding an old bike rim, check out your town’s local bike collective. They might have an extra you could buy or have.
  2. Clean the bike rim of any cobwebs, dust or dirt.
  3. Lay out the house numbers in a well-ventilated area. Cover your work space with newspaper. Apply an even coat of spray paint to the front of the numbers. PRO TIP: Immediately after painting, carefully transfer the numbers to wax paper. This will allow them to dry properly without sticking to the newspaper.
  4. Once the painted numbers are dry, attach them to the rim in their designated positions with super glue. Glue the 1 and 2 next to each other to create a 12. Let dry.
  5. Next, put a battery in the square piece of the clock kit, and glue the kit in the center of the rim. Make sure to leave enough room to change the battery.
  6. Glue your sprocket or decoration, in our case an acorn, on top of the square clock piece. Let dry. PRO TIP: Make sure that your decoration has a hole in it that allows the nub of the clock kit to peek through. This is where we will attach the clock hands.
  7. Follow the instructions in your kit to attach the clock hands. We screwed on the rubber gasket, then the brass washer, mounting nut, hour hand, minute hand and open nut.
  8. Set clock to appropriate time.
