Finally! That what I said. There is always a first time and I won’t forget the feelings of building mine own first Esk8. I approciated this amazing world last year with a Koowheel. A cheap pre-built board that I really enjoyed until it broke after 2 months. Since then I kept thinking about the next board, whether another pre-built or follow the DIY way. I am not new to build stuff, but I didn’t know anything about bulding an Esk8. I like at first eskating bacause it gives me the snowboard feeling and I don’t have to push ! Luckily I sticked to the DIY solution. So my needs were short, silent, decent range and power, and most important COOL! . Budget 500 Euro (little spoiler I went slightly above but not that much). I started reading the forum and soon realized that all the knowledge needed were there, so no excuse anymore… Phase 1: Planning
Parts:
- Custom made spot welder. For friends called the Frankenstein spot welder. Wood, trasformer, arduino e patience. Not astetic but functional!
-
Custom 10S3p Samsung 30Q battery. https://www.nkon.nl/
-
BMS 60A https://www.aliexpress.com/item/10S-60A-bms-Li-ion-large-high-current-BMS-PCM-with-SAME-discharge-port-for-electric/32829800932.html?spm=a2g0s.9042311.0.0.Q9GzVk. Too bulky for this short board but too late when I realized.

3D printed enclosure in spired by the Unik Board one. Mine is way bigger, It takes all the space available under the Spud. I couldn’t go smaller, I do not know way. https://www.thingiverse.com/thing:2867594

3D printed risers. I took inspiration from the boosted board ones and made them to fit the jet Spud. https://www.thingiverse.com/thing:2867604
- Grip tape @e.board_solutions
- Shock pads @e.board_solutions -Antispark Switch @Martinsp
- Bluetooth Module https://www.aliexpress.com/item/AT-09-BLE-Bluetooth-4-0-Uart-Transceiver-Module-CC2541-Central-Switching-compatible-HM-10/32460561807.html?spm=a2g0s.9042311.0.0.YxVVch
- Volt Meter https://www.aliexpress.com/item/8-70V-LCD-Acid-Lead-Lithium-Battery-Capacity-Indicator-Voltmeter-Voltage-Battery-Testers-Tools-R08-Drop/32837990515.html?spm=a2g0s.9042311.0.0.YxVVch. Nice because gives you both Volt (more important) and percentage.
- Wires and other stuffs… AliExpress and Hobbyking.
I really want to thank you all for this amazing forum and in particular who helped me during this bulding. @RedEagle @ElskerShadow @sayekim @Ackmaniac @e.board_solutions (I met him in person, really nice guy).
And now pictures or it didn’t happen…
! Next time I will opt for the wood insert, since witht the t-nut if the deck is not really flat you will notice a bump under the grip tape. I milled down but still visible. Elon Musk heat sink approved I don’t have the picture but at the end I created a 3-4mm hole for the whole enclosure. All the electronics is velcro attached to the board (Velcro from hobbyking, really stong one and thinner than the 3M one).And final result…
The ony thinkg I will probably chage is the enclosure, either I re-print it a bit bigger (too tight fit) and I had problem during the printing (100 hours in total) of clogged nozzle so some parts are not strong as the rest. I am thinking about Kydex. If someone has experience please share your tricks!
Overall I am really happy with how it turned out. My previous Koowheel in fast mode has the same torque of this one in slow mode I am surprise about this hub motor nad the ride with Vesc is way smoother than with ESC. I am still adjusting the trucks but top speed around 40km/h (ackmaniac app, I will post screenshot later), super fine for me, on such short board. The real surprise is the torque that it’s really strong, I set the accelaration curve at -22% to be more gentle but on the steepest hill in my city it bit the street. I can stand on it in max accelleration.
If you read it till here, hey thx for your time! For any question…I am here. Ciao ciao…
EDIT: After request I added the STL files.
