KRG-1 - First build, 12S4P Trampa with custom concave


#1

Hi guys,

Some of you may have seen this board on FB or Reddit, but I needed to create a topic here.
This is my first build, the KRG-1.
I’m French so I’ll use metric system.

Parts list:

Custom parts:

  • Battery undertray ends 3D printed in PLA (both sides)
  • Motor mount protections 3Dprinted in PLA
  • Trampa dampa 3D printed in TPU (softer than the yellow ones)
  • 3D printed concave extension un TPU (awesome if you ride without bindings)
  • Custom belt tensioners made with bearings and speed rings

All my 3D files are here:

Software :

  • Ackmaniac firmware
  • FOC mode
  • PPM + UART
  • Ackmaniac app on Android
  • NFC chip inside the remote. It launches Strava, Ackmaniac app and Spotify when I put my phone on the remote (and send a notification with “Good ride”! ^^)

The board went through different versions:
1.

Very pretty! Well done


#3

Clean build! Please educate me a little- Whats the point of the custom concave? Also, Would you mind linking to some of the posts on reddit/ facebook that you mentioned?


#4

Super clean MTB! The name kinda rings Keanu Reeves’ bikes too :sunglasses:

Did you program the NFC chip inside remote by yourself? Do you have a tuto for it?


#5

It’s actually pretty easy, there’s an app for that! Like NFC Tools for example. No programming at all.


#6

Concave allows better foot placement and carving with no bindings. And comfort.

Trampas are flat for two reasons: the manufacturing process and they are made to ride with bindings.
