Awesome, well done! No welding? That appeals to me

Is it just clamped with the u-bolts? Is there anything to stop the whole thing twisting round?

vlaca2 · Jan 19, 2015

Thanks!

Yes no welding, only u bolts hold the mount. Im testing it a week, its ok. If fail i will report

Looks great! Awesome. I have no doubt that will hold indefinitely. The Ubolts and Ubracket will help with strengthening it.

Thanks!

I saw a broken welded scrub truck( maybe in french forum) so i chose this solution.

One motor, street usage, no jumps, its ok

Looks like you could even fit two motors on their with the ESCs right behind it. :mrgreen:

Thanks for updating the pictures. Very inspiring build, I've been wanting to convert a board like this and I might have to take the plunge!

All we need now is some video of you in action

I have a similar mountain board that I picked up on the cheap.

Love the motor mount. I'm going to try to do that with mine.

Thanks for posting. Great ideas!

What's the weight on your board? Those brackets and mounts look hefty!!

vlaca2 · Feb 15, 2015

Hefty? Maybe, not measured. But the motor 850g (x2 when i install second), i think no problem 2stk 6mm alu and L bracket

Hey mate

First off, awesome board! Just out of curiosity how far or long do you ride on a charge ? Are you still running on the one battery ?
