This project is intended to be one of many open source electric vehicle designs that are easy to build, easy to maintain and easy to upgrade. I call them EZ-EV’s. The original project is a kit car that is still in progress.
This started with the Kickstarter campaign for the Motoped in 2013. At that time there was a new category popping up – the Lightweight Electric Motorcycle (LEM). These bikes were a cross between bicycle and motorcycle, just right for running around town and for easy commutes. I was saving my old Honda CR250 motocross bike for a conversion because it was strong and light. However, I wanted something that could be reproduced by anyone around the world, based on something that could be bought new and was readily available. The Motoped seemed like a good fit.
This is not supposed to be the cheapest, fastest, best looking or best range bike. It is only supposed to be easy to design and easy for others to build.
My goal is to use 3D printers and CNC machines that can also be open source because they are relatively cheap and sophisticated. Once the design is complete, others can buy or build the machines and download files to make the parts with no skills or experience and very little investment. I don’t want to build these for other people, I want to help other people build these for other people.
Tires came in, wheels are being built. All low voltage wiring is done, just needs battery and motor cables. Spose I should set a goal to test by end of year.
This first version of the first vehicle uses a manufactured chassis, but the goal is to develop chassis that can be built on the CNC machines. I had a shop and loved TIG welding so a welded tube chassis would be great but that is a skill that needs to be learned. These machines make perfect parts that are identical all around the world. That means people can do rapid prototyping to develop vehicles, then switch to low volume manufacturing on the same machines. And their parts fit on everybody else vehicles because they are computer designed and machine cut. This is local micro manufacturing or distributed manufacturing. Similar to the way we are transitioning to distributed energy versus centralized energy, every city and town around the world can have a local entrepreneur that builds EV’s.
CAD is a lot like writing software. There is basic coding, advanced coding and architecture design. Regardless, it…
In one way, the CNC router seems very limited because it only cuts parts from flat sheet material. But this is not necessarily a limitation, it is just a different way to design. This Electric Motoped kit is basically two flat sheets of aluminum that bolt to the stock frame to hold the motor, controller, and battery. There are smaller aluminum pieces to box it out, and plastic pieces too but the machine does all the work and it all bolts together very easily.
