You'll need to buy a couple of decent-quality cargo racks, the kind that has 3 or 4 mounting points. It helps if they are the same model/brand.
Step #2: PrevNext
- One of the racks will be mounted to your bike. This particular bicycle is electric-powered, but a regular bicycle will work just fine.
- The second rack will be mounted on the rear triangle of a donor bicycle. The rear triangle is cut out from the frame with a hacksaw.
- The sidecar is essentially made by connecting the two cargo racks together.

The top connecting piece is made from good-quality Baltic Birch, 1/2" thick. I used a handsaw to cut out the square opening, which was then discarded.
Step #4: PrevNext
Two wings, also made from the same birch plywood, are then cut out and all three pieces are connected via piano hinges.
Step #5: PrevNext
The wing pieces are then bolted securely to the top of the cargo racks.
Step #6: PrevNext
A crossbar, also from birch ply, is then connected to the lower part of the cargo racks.
Step #7: PrevNext
The crossbar is bolted on using a pair of these handy clamps. This one has a 1/2" capacity.

Here is the finished product, minus the milk crate I used to carry things around.
Step #9: PrevNext
- The finished product. Here are a couple of YouTube videos:

- This video shows the bike rolling. Note the milk crate; very handy.
