Unless they for the next generation Amflow bike decide to create a slightly thicker version of the Ampace 50480 cell. Just a slight cca 4mm increase in diameter would raise the capacity to cca 80Wh. Total pack capacity would then be cca 800Wh. The con would be decreased cooling properties as...

Ok I see what you guys mean, basically a power split device, here is a nice emulator of the Toyota PSD(long press on the gearset icon opens controls). Just imagine the ICE is the bike crankset. Toyota Prius Power Split Device : Free Download, Borrow, and Streaming : Internet Archive Yes the...

Yes, I think power will be plenty enough. I am just speculating about how much energy will the secondary smaller motor consume as it will be basically working constantly in an emtb environment type of riding. The only time this motor gets a somewhat break is when you/bike cruises at a constant...

I'm interested what's everyone's thoughts on electrical efficiency for the e-CVTs. My thought is that due the fact that it has two electric motors, the final output power(i.e. 1500W peak) will most probably be a sum from both motors, as otherwise the range would suffer a lot or we would need a...

Well this was my opinion, explained better with the help of AI as english isn't my native language, writing technical english is even harder, so I use any help avaliable. Just to calm your mind I double, sometimes even triple check with my own brain what the AI helper spits out, as I am aware it...

The total Gravitational Potential Energy of cca 341 Wh is a real number based on a simple basic physics formula calculated in this case from the suggested 1000m altitude difference, 125kg total mass and standard average rate of gravitational acceleration on Earth 9,81m/s² AI is pretty accurate...

There are some limitations on regen can't be implemented in a way that the rear wheel via the chain and rear wheel inertia would enable regen. I think that this not a viable solution for regeneration on an emtb. 1. It would need a fixed rear hub, that adds problems for full suspension. 2. A...

In an eCVT drive there is no clutch, the pedals are most probably separated from the chainring. Pedals driving the planetary carrier inside the drive, the drive motor driving the chainring. They are so to say on separate axles.

Reading the thread and thinking, is the regen option even worth the hassle and how would it work without a mechanical(chain, fixed rear hub,etc...) connection to the rear hub that brings extra weight and other safety related problems(fast spining chain, huge possibility of derailment because the...

Yes good find, this is a diagram of a coaxial drive like in the 1st to 3rd generation Toyota HSD transaxle. The 4th and latest 5th generations are parallel layout, I think @Ndanger posted a diagram of one. The Gobao and Avinox MG are most probably parallel layout drives as those are newer and...

I think you're missing the point of the e-cvt. The main advantage will be that you will be able to set to: 1. Cadence based assistance - You set your preferred cadence and the drive adjusts the amount of assistance to the terrain, trying to maintain the set cadence. 2. Speed based assistance...

The smaller motor doesn't help the main one it's used for creating a the electrical virtual gear ratios. So depending on the input and the chosen mode it spins and so uses electricity also just like the main motor. My thoughts on efficiency were current ebike motors with one electric motor vs...

Yes I agree, should have been more specific, the other components around the motor itself are usually larger, insulation, controlers, magnet width,...

As far as I can follow I see the main difference between Gobao's unit vs the Avinox unit in the system voltage. Gobao being a 52V vs Avinox with 36V. This is the reason for a slightly bigger Gobao motor(a 52V electric motor is bigger). Interesting choice for their(Gobao) batterys must use some...

This one is also pretty good to explain the inner workings of an e-cvt.

Interesting development in the e-mtb world. Bosch dropping out of Eurobike, wonder what's cooking there. I still think we the emtb crowd are just a few buckets of water in the whole ebike pool where Bosch has a huge share. I am sure Bosch has the know how and the resources to create a...

I don't know, but seeing the slow motion shots of mtb/e-mtbs being ridden hard you can clearly see how the rear triangle gets twisted sideways etc...and with a bit of logic anyone can conclude that a gap like this on this point of the frameset can be a weak point. I don't know, maybe it has a...

A question for those owning the Bosch gen5 version of the Wild. How is this part of the frame holding up? It's held together with a bolt, just like the left Shimano crank. On the Bosch Wild It's on the bottom of the linkage, but on the Avinox Wild they changed it to the top. Gaps like that on...

Well yes it's physics and math, can't cheat your way out of that. Now if they managed to create a motor feel with their tune that hides the drop-off to a degree for the rider, that I don't know. I guess the reviewers and happy new users can report. ✌️

A technical bit about the RS Tune 750W peak and 130Nm, how does that work out. I think someone asked about this. There is a simple formula that we can use... Power (W) = Torque (Nm) × RPM / 9,549 What is 9,549? The number 9.549 is a mathematical constant (conversion factor) that connects...
