E-bike talk: not tech rumor derailment

Having ridden the Pinion MGU extensively, I can confirm it offers some standout advantages:

-Strong torque in gears 1-4
-Belt drive improves suspension feel (or perception of it). I don't think unsprung mass matters much. it's more about the absence of vibration caused by conventional drivetrain weight and associated noise.
-Shifting while stopped is a game-changer, especially when caught in a high gear.
-No chain, cassette, or pulleys to clean.

But there are notable drawbacks:

-Gears 1-4 are noisy, and shifting into 5th causes a sudden torque drop. Shifts into 5th and 9th are rough, though you do get used to them.
-Gearbox are heavy, they also have more drag, which means a heavier battery thus even more weight.
-Belt drive complicates packaging, forcing compromises in structural efficiency, suspension kinematics and frame geometry.


 

Pinion MGU bro! Also, Cavalrie has something coming out and there are a few other prototypes out there, but Pinion is the one getting traction and spec on actual bikes you can buy currently.

Seems like way less traction than anticipated with only Rotwild,Moustach,Simplon,Haibike and Nicolai ? 

Haven't ridden it yet but from all reviews I've seen it seems a bit unrefined atm.

I believe we will have to wait for some of the real big players offerings (Porsche,Bosch,Shimano,Dji...)

Any updates on this? Is it really a Sresh SL ?

 

Anyone got info on the alloy G4 Levo? I've heard it's potentially launching 27/05?

Base build likely to be Marzocchi suspension, DB8 brakes and SRAM 70 drivetrain. Comp build with Fox suspension, Maven brakes and SRAM 70 drivetrain. Both coming with 840wh battery and the 101nm & 666W motor. 

I only saw a spy shot. Didn't look that good. And it probably will be 25 kg plus. Probably 26 kg with pedals and chunky tires... 

Or possibly even heavier if it has a removable battery? Off the top of my head I can't think of an alloy emtb frame with a door for a removable battery, are there any out there?

Isn't it just a plastic cover? That's standard for ebikes. The Gen 3 alloy levo was relatively light for a full power emtb. 

It's not about the construction of the door itself, it's the reinforcement that goes into the frame to enable a door. 

Gen 3 didn't have a door, the battery slid out of the bottom of the frame.

I know. I wish they went for a smaller battery and slide out at the bottom with a more compact motor. I wanna see how low the weight can be with the avinox syst and a removable battery like that. 

Hello! 
Thinking about switching to e-bike over the next years but waiting for the next generation of the trek fuel exe - any info about when what and how on this model ? Thanks to all 

The other site is saying the gen 4 Levo alloy comp is coming in at 25.7kg (S4), so 2kg heavier than the gen 3. Base model is 26.08kg.

None of these e-bikes hit all of the points for everyone and I think the Gen4 Levo is a really good fit for a group of riders that want max power, max battery size, and that so important to some removable battery.

It's not the e-bike I'll be buying next, but I just have different preferences and requirements and that's okay based on what I've learned being on the Relay for the last 2.5 years.

I did find it intriguing that when Francis did the Levo 4 vs. Amflow review, once he normalized the specs tires and forks, the Amflow was only 1# lighter than the Gen4 Levo which had a larger battery and heavier electric dropper to boot. 

Here you go: https://www.vitalmtb.com/news/press-release/specialized-introduces-levo-4-alloy 

But he was comparing the S works model to the Amflow base model, not really apples to apples.

avinox is about 4-500g lighter when you just look at motor + 800wh battery weight, everything else is just a noodly frame with lightweight parts. there is no magic sauce

Nah, motor and battery of the Avinox system are almost 1 kg lighter than the Levo. But a frame without a removable battery is also way lighter. So controlled weight comparison would show that the Amflow is at least 1,5kg lighter. 

It's hard to decipher through the noise for sure, and I don't even know the weight or efficiency of the new Levo motor.

But the DJI motor/ battery combo is 1# lighter than the Bosch. However, the Bosch is considerably more efficient and also has a built-in bash guard, so add $ & weight for that to the DJI, if you can even get one at all and that 1# weight advantage disappears.

So, I agree with the post that states that the Amflow is just a thin frame, with a short dropper, 36mm fork & trail tires installed. It might seem like it's 3-6#s lighter, but it isn't. It's 1-2#s lighter at most.

Is the Unno Mith not the current weight to power winner? Proper dh spec and 21.2 kg. 

I'd certainly say that it is.

About 1# of that weight advantage is the lightweight DJI motor system

The rest is the light frame with a rear suspension design that is also light, a short dropper due to frame design & the high-end build all contribute to that.

It's a dope bike for certain but even if I could buy it here in America, I'm about 97% going with the Regulator CX-R. I prefer the Transition geo; I prefer Horst Link rear suspension & I prefer the Bosch gen5 with a fixed 600-watt battery. The fact that my Avy shock and Hybrid Mezzer just bolts right on, is a nice bonus.

We're probably about 3 years away from getting Solid State batteries in e-bikes, and that should not knock another 2#s or so off.

This podcast is good for the nerds, found it very interesting hearing them talk about regulation and the 'spec' wars:

180 vpp avinox bike would be meeean.

I wonder if those motors are rebuildable? Or shimano bic pens?

Looks rather long and heavy. But maybe it's just the optics. I wish someone would make an Avinox bike with a removable battery. But maybe the system doesn't allow it (yet). I just wonder how low full power weight could go with that option...

The frame design of the Crestline would allow a lower slide out tho. 

Information is limited but it seems the battery is removable on the Crestline

Yeah, their other bikes seem to have some kind of middle of the road thing in where you don't have ot remove the motor but fiddle with more screws/bolts and cables compared to a more quick system. 

Yes, amongst other things. From emtbforums.com:
