Step 1: Bill of Materials
- A bicycle
- A welder
- Extra set of bike pedals/cranks
- Extra bike seat
- 2 heim joints to make a steering tie rod
Step 2: Pedals
Simply use 5" of tubing that will slip over the rod and weld two 3/8" bent rods as in the picture.
With the custom-made pedal in place, weld at a 90 degrees an extended crank and pedal. To make this extension, you will need to weld a rod to an extra crank to achieve the required double length -- about 13 inches. You will not want to place too much of your weight on the outside pedal so use the inside pedal for pushing off and when stopping.
Step 3: Seats
Step 4: Handle Bars and Steering
Step 5: Riding
You then push off while releasing the brakes. I find a few pushes helps to get enough momentum for balancing. Get seated and start pedaling while the passenger begins to help with the pedaling. The bike will lean slightly to one side when there is a difference in the riders' weights but this is normal as it helps in maintaining good balance. Once stopped, both riders should place the outside foot on the ground. Now enjoy an exciting ride in the park with someone special while socializing all the way. Oh what fun it is to ride side by side!
