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
- 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.
500W hub motors (meepo style). http://www.diyeboard.com/dual-hub-motor-9052mm-1000w75kv-power-truck-front-truck-kit-p-558.html

Red Bones bearings
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

- 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…
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.
