I made this Bike rack for two reasons. One: the inability to efficiently store our bike empty bike racks. For example, during the winter when we put our bikes in our basement we have the empty bike rack taking up too much space. This bike rack folds flat and can be propped up flat against a wall. Two: we have bikes with different sized tires and we have bike racks that do not fit all of them. This bike rack has adjustable bars that fit anywhere from 3-5 inch tires.

Step 1: The Shopping List

To start off you are going to need to get these materials:

3: 10’ x 1 1/4 inch pipe
3: 10’ x 1 1/2 inch pipe
20: 1 1/2 inch T Connectors
4: 1 1/4 inch right elbows
5/8 inch Drill bit
Drill
Hacksaw/PVC saw
Mitre box
Eye protection
12: 1/2 inch double wire snap safety pins
PVC Glue
Spray paint (optional)

Step 2: Cutting Your 10' PVC

Once you have all your materials you are ready to begin to assemble your bike rack. You are going to cut your ten foot 1 1/4 inch PVC down to 6 feet using your hacksaw and mitre box. Repeat for all three 10' x 1 1/4" PVC. Using the extra cut two pieces of 2 feet. Then cut the 1 1/2 inch pipe into 6 pieces of 27 inches and 4 pieces of 22 inches. Now you're done cutting and can put away the mitre box and hacksaw.

Step 3: Attaching the T's to the 1 1/2" PVC

Next you will attach the T connectors to both ends of the 27 inch and the 22 inch x 1 1/2 inch PVC.

Step 4: Assembling Your Base

Next you will be assembling you base. Take two 6 foot sections of PVC and attach it to a 2foot section using two elbows. Leave one end of the rectangle open so you can slide the supports on.

Step 5: Attaching the Support Pipes

Slide the six 27 inch PVC pieces on to one side and the four 22 inch pieces on the other as in the picture above. Next close the base with the remaining two foot base using the elbows to attach it

Step 6: Attaching the Top Support

The final step in assembling your bike rack is sliding the remaining 6 foot pic through the ten exposed T's to form a triangle as seen in the picture. The four 22 inch pipes are supports at the back of the bike rack and the 3 pairs of 27 inch PVC hold the bike upright.

Step 7: Drilling the Holes and Securing the Bars

Now you are going to position the supports to fit your tires. Then you are going to take your 5/8ths inch drill bit and carefully drill holes through the T's and the 1 1/4 inch PVC. To make the rack adjustable slide the Ts slightly further apart to accommodate larger tires and drill a second hole only through the 1 1/4 inch PVC. Next insert the safety wire snap pins trough the Ts and the 1 1/4 inch PVC to fix the bars in place. Now your bike rack is complete and ready to be spray painted and glued. The only pieces you will not glue are the back bottom four supports (the 22 inch pieces). To fold pull the back four pieces put of the base and the rack will collapse. Let me know what improvements you think I could make to this innovation.
