It’s not an esk8 build but I feel an electric unicycle is more akin to an eboard than an electric bike so I’ll post here.
I am planning a build similar to the Gotway with a more powerful 3000W motor with a 20.9”x2.75” tire. It will have a 20s3p 30Q battery and will be controlled by gyroscope and accelerometer connected Arduino with a DAC output to control a Kelly speed controller. I will make the frame out of 1” aluminum tube with CNCed plates brazed to the tube to hold the wheel axel.
This project is going to take a long time and I’m just getting a parts list together now and drawing up plans. I plan to log everything in this thread for anyone interested. Stay tuned for blueprints & parts list sometime in the next few weeks!
