Avinox Reveals its Motor Gearbox

Unless someone starts to make something like the VEER Split Belt Pro !

never saw those in the field. probably a reason for it

Worst case the belt will skip a cog or come off? Assuming there is a tensioner. The last month I've had 3 cog skips, or at least that's what I think is happening. Something akin to a worn chain jumping a tooth but with a different sound.

Does your bike have a snubber? Is there a spring tensioner employed (usually not for hardtail city bikes)? Fixed tensioner? Are there horizontal dropouts sliding rear axle to place increased tension on the belt?

An unbroken/continuous rear triangle (parrellagram?) like that couldn't even use a belt. There'd be no way to install it.

VPP and DW4 style designs, you will probably never see a belt drive for this reason, unless they design a very elevated chainstay.

Maybe we need single-sided swingarms for this, or the previous model Ibis Oso design that everyone hated.

Others have found that belts can experience unseen damage when packaged even a little tightly. Then fail shortly after install. So, if you try and roll the thing up in your hydration pack, thinking that it'll save you down the road/ trail, it likely won't.
If you think about it accessory drive belts on an ICE are packaged in a way that doesn't overly flex them either, probably for the same reason.

Agreed. Maybe this is where something like a VEER Split Belt Pro could come in handy. Basically make a version of with multiple pivots to put in a pack and used temporarily to finish the ride. Either that or assume that Gates belt you stuff in your pack is there to just get you home, and it swap out with a unfettered one.

or use a chain and just carry a spare multilink and be done with it

Yep. You can always do the simple, expedient, and reliable thing, that has worked for over a century. Of course, the requisite chain tensioners required look an awful lot like derailleurs; the very aesthetic you not want to not be reminded of with your new ECVT bike.

But why bother when you can take the plunge and proudly show off your belt drive on your MGU/ECVT bike because no derailleur bike can, creating caste like the Star-Belly Sneeches. Just a glimpse of a belt on your EMTB means you are in an elevated class

Maybe you missed the already displayed chain mgu Avinox photo one page before this one…

I'm well aware and in the end chains will probably be the more prevalent choice for MGU EMTBs. The operative word here is choice, because with derailleur bikes you don't have one. They don't get to put "Stars Upon Thars"

are you dumb? both need a tensioner…

 

[urmom]

I have Pinion MGU with chain.
My friend has Pinion MGU with belt.

Both are full suspension with tensioner. Belt feels a tiny bit spongier, but there is no real difference. We note no difference in efficiency. Belt is lower maintenance, but a big ass chain that doesn't need to flex sideways has also a lot of durability.

(Side note: I think the resale value of my bike just dropped 2k. Thank you avinox!)

Specialized might have something to show off later this month a Whistler Crankworx according to a user on another forum.

Edit: Wrong thread!

Specialized do not normally show anything off until it is ready to purchase and with the dealers.

I would take this with a big pinch of salt

Full suspension "adventure" type bike with spring tensioner pushing belt up just below the chainring. Same design as Pinion MGU. Initially I had the Bosch dynamic setting set to +5 in turbo (power agressively coming on), and I think the belt cog jump may have been from standstill. I've since reduced the dynamic setting. Maybe the spring is a bit soft.
