I don’t understand why people care so much about drivetrains. I’ll ride anything. I can’t see myself feeling differently about motors. All of the eebs I have tried have worked great, over an 8 year span even?!?
Try a 2x or 3x drivetrain back to back to a modern 1x12 drivetrain and I'm sure you won't be able to keep saying there is no difference...

Geometry was under the bike designer's total control though. With the benefit of hindsight, it turns out Chris Porter was right all along and almost everyone else had to be led by the nose to where we are today.
Correct. Then why don't even 5 year old bikes fit 240 dropper posts? Why are the seat tubes too long?
As for Chris Porter I think we saw that while geometries went towards what the Geometron is, generally they took a step back to something less extreme. We don't have the final state, but still. Not everybody is racing at full tilt.
1 CBF is dummy easy to do with a Horst link. IMO the kinematics have some advantages over the dual link setup.
2 this looked more like a “Mr. Miller we make you custom sample bike” from an Asian factory rather than something that’s about to go to market. Especially considering market conditions at the moment. However id love to be proven wrong, looks like a cool bike!

I don't really want to ride Altus or Sram NX(but I'll still have fun if I do), but I'm with you on the ebike thing. As enthusiasts we care a lot about the best, all the old dudes on class 1 ebikes seem pretty stoked regardless of the drive unit that they're on.

I don't think seatubes are too long at all, rather insertion depths are not long enough and all over the place to easily know what will fit and what won't. And geometron geometry works on slow trails as well as fast trails as long as you trust the bike and are active rider, it's not for passengers. Only trails where it's not fun is deep ruts with tight turns where obviously both wheels don't fit inside the rut at the same time.

Honestly my favorite bike I have ever owned and ridden was 3x friction shift. NX isn’t bad either, but I just ride in my lowest and highest gears and I don’t care about being fast, so I know that I’m not the average rider in that regard

As ebike take more (and more) market share, their development will be the main thing for most bike brands.
Choosing the e-system is a lot of the times more important for sales than suspension kinematics or a dialed geo.
Dji has pointed the direction in terms of performance and form factor and the rest will have to follow.
Already today when I see a Bosch equipped bike with an 800w (fat) battery, it looks outdated .Same goes to the new Levo, new Giant E reign ... When you compare their form factor to Amflow,Unno,Megamo,Forbidden ... it just looks outdated.
For Shimano, I think their problem is the brand culture. They are not a brand that likes to change a main product every 2-3 years , and with e-systems you have to do it in order the stay relevant.
So you think the e-bike motor (Avinox) that rattles by design, is 10-20% behind the Bosch on efficiency, utilizes cadence instead of torque based assistance, has no chain ring protection, has a higher center of gravity due to battery shape, and overheats constantly on the dyno and derates is the correct direction huh?
People are just way to obsessed with absolute power and aesthetics. All of these full power motors can produce way more than 750watts. Actually the correct direction is the Maxon; a smaller motor that can still produce the 750w Class 1 max. Combine that with high efficiency and a Solid State battery and we'll all have 45# Class 1 full power e-bikes by 2028.
I just ordered a new e-bike and Bosch Gen 5 was the primary requirement.
Local shop told me that a replacement for the Yeti SB160E is launching next week (presumably Tuesday, the unofficial launch day of new things). It might use the MT-something name. Should be 160 or 170 travel. Full power Bosch motor. Very expensive, as expected. Dentists rejoice!

The "only shifts at the ramps" thing is a myth that SRAM isn't going out of their way to correct. There is no sensing of position, torque, or anything else going on -- so it's simply not a real thing. It was just rate limited to make sure us hoons didn't blow up chains too quickly. The existence of Transmission mechanical groupsets is evidence enought that you can bang shifts as fast as you want and things are hunky dorry.
Interesting, but it doesn't know your cadence, so this is an approximation at best. I'm sure most riders are operating in a predictable cadence range, so...
Interesting, but it doesn't know your cadence, so this is an approximation at best. I'm sure most riders are operating in a predictable cadence range, so it's likely better than nothing. Nevertheless, the root of this discussion is the news that they removed/increased said shift speed limitation.
You‘ll find this information even from SRAM directly. The system is simply guessing when to shift based on an algorithm. That’s why sometimes you get some „loud“ shifts under load.

Are ebike motors getting smaller? If not would it make sense to have a universal mount standard? Give options for motor swaps. just a thought, might be a dumb one.
Stiffness of the shell the motor sits in is more important than you‘d think apparently. I am not a specialist but it makes sense to me since we have different power and torque numbers as well as the freedom for motor manufacturers to operate with different layouts. Belt driven inside the motor, motor around the spindle, mgu etc.
I would love to have a UDH thing for motors but peeking over to other power vehicle industries I think it is very unlikely for various, valid reasons.

I'm prefacing this with a disclaimer that I've not used transmission; but does the mech not put a slight side load on the chain, and when it detects a change in side pressure due to a shift ramp coming around the cassette it then completes the shift?
This would allow it to "sense" where the shift ramps without a specific position sensor, or a cadence requirement.

No, it does not.
There are no 'sensors' measuring any sort of side loads from the chain or anything else.
This is how these daft rumours about transmission come to be. You've just made a statement that isn't based on any facts at all. Did you just make up a guess at what you think it 'might' be doing or is that something you read elsewhere?
Information on exactly how AXS Transmission works is freely available online from SRAM themselves.
My understanding is that it has that feature where you can slightly move the pedals backwards and it completely disengages the hub so it rolls freely and has no kickback at all.

What’s Berrecloth on… 😬
Im definitely, absolutely, not trying to be a smartass or anything… but wild guess says its a bike.
Or a moped.
I wouldn't rule out drugs as well Mkay...
Based on prior judging decisions, crack cocaine
Ursa = bear. Bearclaw bikes.
This is starting to take a dark turn towards some hard drugs and Im confused why…
I thought it was a old Chumba badge 😂
AI is good for some things I guess! From the AI-generated summary that sourced the Ursa Bikes patent app:
https://patents.google.com/patent/CA3155940A1/en
Lol there is an “electronically assisted strider” in under that persons name on the patent site.
Looks like he also did a lot of work for Rocky Mountain.
Something new coming from DT Swiss the 18th

Probably the Sidekick-like hub internals

It’s going to be in the hubs, similar to the ones from e13.
