First let me start off with a big thanks to the community on this site! This site is packed with lots of great info that helped me a long way.
I’ve recently started my own electric mountainboard build. I finished restoring and upgrading my old MBS atom 85 board by reinforcing the deck and replacing the tires and bearings. Also my 3d printed drive gears and motor mounts are nearly finished.
Here are some pictures of my progress so far:
I’m now at the point that I want to order all the electronics for my board, like the motor’s, vesc’s, batteries etc. Based on the informatie on this site I’ve made a selection of the parts I want to order, but before I do I hope I can get some good advices for you guys to see if my setup is correct or that I’m about to make some mistakes!
I’ve calculated the following setup with ESK8 Calc:
I’m looking for a top speed of about 30 - 35 km/h (my weight is about 70 kg). I’m not planning to use this board on offroad terrain, mainly regular roads or light gravel roads. Is my gear ratio correct? Is the motor KV correct, or should I use a higher KV of 192? Could I decrease to 6s with a 20 teeth pulley? I’m not sure which combination is better, I hope you guys have some tips or suggestions.
Based on the above calculation I want to order the following parts:
I really would like to know what you guys think about the usability of this setup. As I said i’m not looking for a very high top speed, about 30 to 35 km/h is good enough. I do want a board that has enough torque and that has the ability to climb slightly medium hills.
Thanks for all your input and suggestions. I will report the progress of my build in this thread!
