Yes this set up has been proposed. It would be awesome if it can work properly. Saves a vesc and you get power to both rear wheels. The braking I assume would still be better than mono set up as more forced braking through both patches of wheels. The belts would take a pounding though wouldnt it. Meaning its questionable how long they would last.
I love the Chatter on this topic!!!

It would also be great if you could get fire jetting out the back.

He also, Handled that with the carvon hubs on the front of the board.
No brakes would be a deal braker

Seems more like a clutch system instead of differential. And since they use it on their 4WD they can get away with no breaking since they could use the hub motors for braking
This is part of Carvon’s EVO which he is patenting
I do not think he is selling this as a truck only unit (just a guess)

Oh whoa hub motors and a belt drive that’s crazy where can I get more info for this
Just email him lol
I like the idea but needing hub motors for braking negates the gain you get by being able to run only one motor between 2 wheels. 4WD is total overkill for an esk8, unless it’s an all terrain board. IMO this would only be a game changer if it had brake functionality.

there are cheaper ways to add breaks to a longboard than hub-motors
It has brakes.
If he is using one way bearings on the small gear any time brakes are applied the motor would lock the bearings/gear which would make braking turn into sliding…could be fun, but not the gradual brake everyone is used to. This would make sense than that he is using one way bearings in the small pullies and why he is using this in a awd setup with hubs in the front, since he can use the hubs for braking and set up the rear to not have functional braking.
Was kind of hoping he may have found a way to make this work like a conventional differential, but it seems more than likely that he has just used one way bearings.
Here’s one for the Carvon owners…
If you had the extra motor at the rear…and it did not have brakes…would the dual hub motors be able to slow you down enough?
Just as a guess…I would assume if the rear dual was just a pusher and coaster (I’m guessing) …the dual motors would enough to stop you…
Ok GO!
Edit Additional thoughts:
Hence my thought this will not be sold as a single unit…it must be paired with the regular Carvons…because these are not intended to stop you…Just push and coast
From Carvon Facebook:
No LSD, but it has one-way bearings inside the motor pulleys, allowing for freewheel and the outside wheel to go faster than the inside for proper turning. That also means it can’t brake. But the Dual Hub motors in front takes care of that. Basically, it provides torque at low speeds and disengages at higher speeds. It gives the board the torque needed to climb hills and coasting/top-speed of the hub motors.

any pictures of this setup? I’m intrigued
Ohh …I didn’t even read that and I got it right 
I just saw a picture in another thread. gee, its a a pretty complicated setup. I can only imagine it would be noisy?? still props for doing it first!
I’m struggling to understand how this is better than a dual belt driven board. With dual hubs up front it wouldn’t be lighter, unlikely to climb or stop better, I guess it could have a higher top end, but so what. Maybe I’m missing something…
