Who needs a E-Fatbike??? (former Moose Manic 2 post ;) )

[Guyt]

I have the EP8 on my Spherik (3,200 km) and the EP801 on my Rise (1,800 km). So far, no problems, but I must admit the rattle when not pedaling on rough terrain really annoys me. It's not an issue on the smooth snow trails I ride in the winter, but it's another story when rocks and roots reappear in the spring. The new Bosch CX is very quiet according to what I read.

What I also like about Bosch is that they force the manufacturers to use their Bosch batteries. Shimano is more flexible, allowing manufacturers the use their own batteries, like the Orbea Rise. Just between us , I am a bit insecure and would feel better knowing a Bosch battery is available at every street corner. Not too sure it's going to be easy to find a Rise battery in a few years from now.

So, my next E-MTB will be powered by a Bosch motor! No noise, no worries

Have you tested and compared these motors?

The EP801 vs the CX gen4 Smart System?

The EP800 and EP6 are generous motors at lower cadence, meaning you get lots of power even though you're pedaling slowly with little force. But those motors drop off as you approach 100 rpm, so it feels weaker when going fast. The EP801 maintains the low end power while improving at higher cadence. Sure, it might not be as powerful as the CX gen4 as you go above 100 rpm, but the Bosch is less generous when pedaling slow&calm.

And the EP801 really came to life with the recent 4.3.0 firmware updated that allows you to adjust motor overrun and how close it will go to cutoff speed before ramping down the power. In the most aggressive settings, it feels racier than the Bosch CX Race.

I think it's a good thing having a motor that is generous at low cadence when riding in deep-ish snow. It can be exhausting riding in powdery snow, and it's nice having a motor that is powerful from the get-go when you're stopping and starting a lot. Especially when you come to a stop in a climb and try to get going again.

I rode a Rock Machine fatty with the EP6 (if my memory serves me right)

Speaking of overrun, I was talking to a dude who was adamant the ep8 doesn't have it but both of mine do. It's not adjustable but the motor does keep going for a second after you've stopped pedalling.

On the 801, how vast is the adjustment range and how long can you make it last? @knut7

The difference is huge. Previously, there was a short but noticeable shove. But it was a bit difficult accessing it as it would cancel if you backpedaled ever so slightly. Now, you're allowed to move the pedals back a bit. I try to illustrate the behavior in this video.

Perfect, thank you!
