So, this random thought I had.
Would it be feasible to fit hub motors and belt drives in one board?
Belt drives have certain slip to it, so acceleration wont be instant (unless its dual diagonal drive, but i still think it slips slightly)
What if the hub acts as its initial pull to accelerate, and maybe during the rest of the ride, it lays off to the belt to let it handle speed etc, and the hub can do the regen to the battery.
Does this even make sense?
. . . . no
That was harsh…
I’m not sure how this would work out. But I’m sure I’ve seen a 4wd here that had two hubs and two belt or chain, can’t remember. So it is possible. Search for it and I’m sure you will find it here. If you are proposing to use regen on the hubs while the belt motors are pushing that won’t work for sure. Your belt motors will have to use much more power while pushing than the hubs will be able to regenerate
Idk if it’s possible/practical or not, but if it is, I think it would make more sense to do it the other way around: belts initially for acceleration and the hubs for higher speeds
You know when you’re about to fall asleep and your mind comes up with some wacky and very impractical ideas. Well I had basically the same thought last night.
I have a terrible single hub drive spare in the workshop and was thinking if you could pair it with a belt drive. So on the rear you have one hub and one belt. The hub would provide the extra power on flats but the belt would do all the work on hills. If you ran a loose 9mm belt so you didn’t get too much drag.
I assume the extra weight and drag from the belt would make it useless. But an interesting idea.

Also, cars usually weigh less than 5kg until they hit 30km/hr then they are usually around 1500kg
The 4wd concept sounds interesting 2 hubs upfront 2 belts in the rear. I wonder how that would play out. Or maybe hubs in the back for sliding.
Does this design mean 2 remotes?
This is an old concept and has been done many times. Carvon has a board like this single large motor on one end and dual hubs he other
Honestly it is kind of a weird idea? I don’t think the hubs would stand any chance against the belt drive. I think that the belt would overpower it every time.
The only things that have come close to the torque of the properly configured belt setups are the Raptor 2 massive hub motors, Carvon direct drives, and the new hummie drives that he is currently working on.
Most of the China hubs (Landwheel, Meepo, Benchwheel, etc etc) are all hard to compare to. For example, my landwheel L3-x, the new one, is like a Prius, and my DIY board with dual 6355 motors is like a Tesla.
Also just another note, as far as I am concerned, a properly setup belt drive should have zero “slip”, if you have belt slip, you gotta set up an idler or tighten it up a bit.
Lol maybe the other way around (hubs in front), the hubs thane would get destroyed in the back xD
50 miles and my Landwheel is already chunking like crazy
This. This was EXACTLY what happened.
Totally forgot what my brain was going through. But it shouldn’t be 2. (I know it doesn’t make sense, stop telling me it doesn’t make sense.)
Like some cpu inside it to switch around from hub and belt in one remote. AGAIN, no sense whatsoever.
ITS JUST A RIDICULOUS IMPRACTICAL IDEA CONCEIVED BEFORE SLEEPING.
sheesh
Heres the thing, its possible. One of the moderators here have tried it before with unbalanced dual drive. Technically how it works is the other way around of how you describe it. The belt drive have more initial torque due to reduction, so it will be the driving force from static stop. Hub drive is best played during high speed as the way BLDC motor works (requires movement in the magentic flux to determine which phase wire to be electrified). Therefore the hub will perform the pull well to the higher speed than the belt drive. As so this is the hypothesis.
In practice, this works too. Belt will give higher torque and smooth start while the hub will pull you up in speed. But what you’re trying to achieve, the difference, is not significant. It will just be all in all smooth transitions.
If you have proper dual sensored hub or dual unsensored belt in what ever combinations, it works quite well and efficient. So to say, its doable but no significant impact (just more cost).
So how 2 different speed works? it comes back to the rules of electricity works with load. Basically each motor and each esc / vesc will share the load. Just like if you’re on downhill road, you still roll but use less electricity. Same goes by with dual uneven motor or drive.
This should end your questions and thoughts 
Definitely did. Thanks!
