An important highlight is that i'm releasing all source files for the build: https://github.com/eroldan/OpenEMoto
The project is made on Autodesk Inventor.
What is missing now is a guide of the build process. Writing one is a big task. Let's see if people is interested. I can answer here for now. About the build process I can say that I've built this bike with:
- TIG welder
- Angle grinder
- Press drill
- Car type hidraulic bottle jack (2 ton)
- Lot of mild steel
- Drill bits and cup saws
- Printer+sticker sheets
- Small hand tools
- Few dollars for a lathe operator
- 3d printer (to build the welding jig)
A waterjet or CNC plasma cutter probably can accelerate the build by a big factor. I've cut the plates by angle grinder, and some are tricky.
As you can see, i've tried to design in a minimalist way to easy build and reduce weight. I think it is impossible to get rid of any part without taking some function. With my 720Wh battery, the bike is weighting 40Kg.
The design goes toward a trials bike (style that I enjoy). The seat is low, and that makes dismounting very easy. Probably a new seat mount can be done to make it more "enduro".
Does anyone want to build it?
I will post videos soon. My riding mate & camera man is on vacation.
