How to Make a Bike Trailer from Scratch

Neighborhood yard sale and you can't drive. How can I carry this stuff back to my house? Here is an easy way to make a very sturdy, simple and reliable bike trailer.






Step

1. 1
   Look for any scrap wood you have around your house. If you don't have any you can buy some at a local home improvement center. While you're there, buy solid woods such as oak or maple, not pine, because it is a very soft wood.

   Look for both plywood and 2x4 planks. Both of these are lightweight so it will be easier to tow on a bike.
3. 3
   Make sure you have plenty of wood screws. Depending on how sturdy you plan on making it, get 150 - 200 screws.

   Space the axle a few inches out from your frame so the wheels have enough room to move.
8. 8
   Attach the wheels. There are a few ways you can attach the wheels, you can use a threaded axle of drill into you axle with a small metal drill bit. Attach pins to both sides of the wheel on the outside of it and also the inside near the frame. Make sure the tire has no friction between the pins and the frame.
