Hardware Store Special onewheel build.

I wanna start documenting this build, cause it’s gonna take a while and it’s more fun to post updates.

So I kinda got obsessed with vesc onewheels last year.
After doing some research my strategy is basically “cheap out on everything except the motor”.

Once again a lot of my choices are driven by shipping logistics, or rather lack of proper logistics for proper parts.

Originally I was thinking about Superflux motor, but at 10.5kg it’s too heavy, and Fungineers didn’t have shipping to Serbia at that time. And then I found a cheaper used XR motor (7.5kg) together with fresh Thunder tire and cold blocks installed, all with ebay international shipping from US.

F it - YOLO! Couple months later got my motor:

This is the plan:

Center - 60x25x2 square tube, ends - 40x20x3 tube:

Swappable 20S1P tabless pack, battery box with a compliant TPU hinge:

Locked with 22mm hood clips:

Slowly collecting parts.

I have 2 UBOXes 100v100A that I was planning to use for Kicker 2 build, but I ended up using FSESC 6.7 on it.
Cells are Tenpower 50XG.
Something my metric mind cannot comprehend - inner screws on XR motor are M8, while outer are 5/16-18TPI
I ALMOST tried forcing M8 screw and almost ruined the threads

The bastards! Your wheel is gonna crash into Mars at this rate.

Cool concept, I’m looking forward to how it turns out. I would humbly recommend that you also don’t cheap out on the ESC, that’s an easy way to get burned.

So you are building your own rails?

So cool.

Have you monowheeled much before?

What do you think about these UBOX lites? I’ve heard good things about the bigger 150A version. But very little info on these.

I’ll probably upgrade later if I like it.

Yea, I want to replicate X7 or WTF rail geometry, since I have no idea how it’s supposed to ride.
Also no idea if square tubes gonna hold up.

I’ve ridden EUC a bit. Never tried onewheels.

I’m not sure if the “fang wheels” or whatever they are called even work, but I’ve designed them anyway.

Since it’s gonna have a swappable battery it needs an antispark somewhere in the system.
And from what I heard, most antispark connectors like xt90S are not rated for repeated high voltage plugging.
There are AS150 antispark bullet connectors, that are self contained:

I’ve figured if I use 2 antispark pins, they can handle twice the voltage:

As long as you’re not using flipsky ESCs
