The Choprical Fish: a Human Powered Party Bike

Step 7Design a resonating chamber.

Design a resonating chamber.
OK, now the bike you've designed or acquired is ready to ride. It's time to turn your attention to the resonating chamber. It needs to be rigid, attractive, and large enough to have adequate bass response.

On the Classic Soul Cycle, I had used a bazooka bass tube for bass. But on the Choprical Fish, I wanted all the lines to flow, so I needed to build the subwoofers into my cabinet. I used SketchUp to create an accurate scale model of my bike and design the speaker cabinet.

At this point in the process I didn't know how I was going to build the cabinet. So I thought it was important to do the design work in a 3D CAD program in case I would use CNC tools to fabricate it.

Had I known more about custom fiberglass fabrication, I wouldn't have spent so much time in this phase. I would have done more drawing and less CAD work, knowing that I was going to sculpt the form by hand anyway.
