For my final project, I am working on building an electric longboard. This idea came to my mind when I was thinking of a project that would incorporate both engineering design and aesthetics.
I have always been fascinated by longboards and the way they work but I have always wanted to add a motor so that going uphill would be a little easier. Unfortunately, it’s not as easy as just attaching a motor in. We have to make considerations for the speed, torque, amperage, stability, acceleration, and many other factors.
I also have to consider the different aesthetics I want to portray with the longboard. I have always dabbled around with sketching and I think this is a great opportunity to channel my creativity. The three aesthetics I am considering are:
Native American Art, Cosmic, and a Simple Geometric aesthetic

Another challenging aspect is the design of the electric hub to store all the components. I have used the OnShape assembly created by Arvid Hedler to modify a design of a longboard and add features that I want.
The longboard on the surface looks like a regular longboard but when we look at the rear, we can see the electronic assembly. This assembly consists of the following:
- VESC – to control the speed
- Battery pack
- Motor – to turn the wheel
- Pulley system to take mechanical advantage
These are the basic components, there are a few more parts that are smaller but still very crucial. I think this will take a long time to design and create but I am really excited to build it!
So far, I have worked on a small prototype and I have started cleaning my current longboard. Here are some images from the process:
There is still a long (and expensive) way to go to get to my end goal, but I am excited to get there!
