Here’s a quick build page. I didn’t take many photos during the actual construction, but can share what’s in it, how it all went together, and a couple issues I had. But first the finished product:

Here’s a diagram of how things are hooked up:

Putting it together:

  1. The enclosure was used and had a couple holes in it. I ended up using painters tape on the outside, then applying several layers of ShoeGoo mixed with a couple drops of black modelers paint. This filled the holes nicely and should hold up to the abuse.
  2. I cut new holes for the XT90S, charge port, and battery meter using a soldering iron with a flat tip. The fumes could be toxic, so I basically held my breath the whole time, had a window open, and a fan running. I cleaned up the edges with side snips and a box cutter. They’re all mounted with ShoeGoo.
  3. The battery, BMS, VESC and receiver are mounted with industrial strength velcro.
  4. Most of the wiring is 10AWG, but I didn’t want to unsolder the leads from the VESC, which I believe are 14AWG.
  5. The BMS is wired for charging only, bypassing the discharge circuit, going directly to the VESC from the battery.
  6. For the battery meter, I did a temporary version on this mod. I stripped a couple wires and used electrical tape to keep them in place, then powered the unit on holding down FDn, and touched the two wires together to get the function menu. Easy-peasy.


  1. One thing that really threw me for a while was when I couldn’t get the 2.4GHz remote to make the VESC go. After much poking and prodding, it turns out that the sticker on my Rx was on upside down, so I was plugging in channel 3, rather than 2. Note: you have to look at the hard-to-see stamped numbers, rather than counting from what you may assume to be the top. :rolling_eyes:
  2. With this motor mount, I really should have filed down some of the hanger to get it seated further in, but I didn’t want to ruin anything, and I don’t have a file or dremel at the moment. The 12mm wheel pulley sticks out far enough to hit the socket head screws, so I had to use 3 speed rings to get enough clearance. No big deal though.
  3. With the 90mm wheels, I had to use 1/2" riser pads to get enough clearance to avoid wheel bite.

I really haven’t had any other issues, and everything went together pretty well. I’d really like to run FOC to quiet the high-pitch noise when accelerating/decelerating, but I don’t have the $ to replace the VESC if it dies, so I’ll stick with BLDC for the time being. I also think running some non-clone wheels may give a smoother ride, but after the first ride, I’m a very satisfied customer. Thank you again!


More pics please!!

What enclosure is that?

love the name of this board

Wow, that’s so freakin clean! I love it! Even your wiring diagram is neat and clean. And obviously the name is fantastic :stuck_out_tongue:

I wanna see more of this build.

hey whats your tops speed and range?

Great looking build and really well thought out diagram! Would be super helpful for all the “how do i bypass BMS?” questions we get non-stop…

Well done sir!

One minor critique - i would replace the socket head bolts on the motor mount w/ lower profile bolts, and flip your motor gear so there is less leverage and you run it closer to the motor plate.

It’s a @psychotiller 25" Monolith Low Pro

I have no idea yet. This is not just my first esk8, but my first skateboard in general, so I’m taking my time getting comfortable. The gearing is probably a bit low for a high top speed, but it handles hills nicely. I may swap to a 16T motor pulley later, if I feel the need for more speed. Once I brave the full trigger pull, I’ll update here.

Thanks for the suggestion, that makes sense!

There are a few more things I need to finish up on here. First is the motor sensor wire, then the bluetooth module so I can try out the phone app. Lastly, I want to find a good, but cheap lighting solution. I may just end up going this route.


How do you Charge all them batteries?

Did you Direct solder groups together?

Your build is so clean! It looks fantastic.

Is your enclosure waterproof? I see there is some kind of weather stripping along the edge?

They’re soldered together is series and charged with a 10s BMS and a 42V power supply. Charge times are high, but the ease of use makes it worth it.

Thanksn there’s some weatherstripping around the edge, but it’s not totally waterproof because the enclosure is two overlapping halves and theres a hole where the wires go to the motor. I just don’t ride in the rain.
