Don't you hate it that when you want to go over to a friend to play ping pong you can't because he lives in a flat and there is no room for a ping pong table? I know I do.
Here is the solution :
With the pingpong bicycle (for the brittish : wifwafcycle ) you finally can go anywhere and take your ping pong table with you.
Hours of fun ping ponging in the middle of fields, on pavements, on squares in the city, even on the road (this is not adviced)
are guaranteed with this easy to make yet proffessional grade ping pong bicycle.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Find Old Bicycles and Metal Tubing
Find an old bicycle to cut up
Finding old bicycles can be hard in some parts of the world, there is a good instructable on buying used bicycles if you click here, but i advice to look for free ones (i'm just cheap)
Then you need some metal tubing. if you're lucky you can find tubing like i did (already tube welded on 90 degrees).
Step 2: Put It All Together Into a Frame
Put all the parts together and weld it up.
There is a nice instructable on building a cargo bike if you click here, for this you can follow untill step 7.
If you're really going for a zero budget bike (except for some welding elektrodes an elektricity) you can in stead of buying ball joints make your own steering rod couplings like I did :
I took a bolt and welded it to the front fork.
On a tube that fitted around the bolt I welded another bolt.
On the steering red I welded another tube that fitted around the bolt.
Check out the pictures if this isn't clear.
Step 3: Rework the Frame
The frame actualy needs to be quite long
If you plan to put on a competition size ping pong table. Then you'll need 137 cm (src : http://en.wikipedia.org/wiki/Table_tennis )
so weld on some more tubing.
Take the old support structure of your donor ping pong table and try somehow to weld or bolt it onto your frame.
Think about the tables and that they need to be able to fold otherwise it wil be impossible to ride te bike (it will be hard enough as it is)
Step 4: Add Pingpong Table to the Frame
If you want to put it all together you should check if you have everything:
- steering system
- 2 sides of ping pong table
- old stands of your ping pong table
- net (I made mine out of a piece of cotton)
- kickstand (otherwise you're thing will fall over)
- brakes (safety first)
Just bolt everything together
Step 5: Play Ping Pong, Ride It or Just Enjoy Your Work
and eventualy hack it to pieces reweld it and make it ready to get a barbeque on it next spring
