I felt compelled to share the following pics of prototypes I may work on in the future. My next model is going to be 16″ wheels. After working on the heavy 20″ back wheel and seeing people on scooters that seem to have 10-12 inch wheels, I’m going to stick with 16 inch wheels moving forward!
The pics below are for a 12-16 inch wheel design. In case you’re wondering where are the spokes on the wheel, they are “covered” with yellow wheel covers.
The quad design is below. I have a top view (second pic below) to show that the construction is similar for the front and back of the frame.
To make it easier on my eyes, I changed the color of the square tubes.
