Very DIY and interesting build. Why did you opt for 3x motors, due to esc availability?

Very nice! Do you have a rachet in both front wheels? Doesnt this mean that both can turn idividually, but you loose the brakes in front?

On off-road, 4wd has great significance. However, on-load reduces battery efficiency, increases weight, and increases motor + esc cost.

So I used a freewheel to lower the rolling resistance while driving 2 wheels with one motor on the front wheels.

I wanted to be able to ride freely without any special changes.

That’s correct. And reducing rolling resistance. I think that two rear wheels were enough for the brakes.

Really nice, you can change between 4wd and 2wd on the remote?

@Pedrodemio It may be possible, but I have not done it yet. I will set rpm limit to be 4wd only at low speed and 2wd in high speed.

Hi, @wayne

I using CAN Bus between rear side two VESC. I using PWM Y cable between front vesc and rear vescs
