There is a company out of Italy (dhsign.it) doing some bushings that work like a spherical bearing, that might not be a bad idea if there is some alignment issues?

I am building my own battery too, that size is correct you won’t get anything bigger than that, it’s tight
Are those 21700 cells or 18650?
18650
From bafang ?My battery is supposed to be shipped today. Fingers crossed for fast shipping.
Just received the same message
Huh, hope you recieve the correct one!Just received the same message
But shés talking about the btf014 ans not the btf100, while we had a big discussion on the fact that I need the 36v and not 43v… I think I gonna have a surprise…
the messages were kind of crazy, she will finally send me the 43v, I think the package was already done, even though I asked for the 36v many times... well, I will change the firmware, not a big deal but the communication is annoying
Nope, just buy it, that’s all…
Try to 540wh with 21700 cells,

About the M820 motor system, I contact with bafang company and they said if anyone who can post a video and tal about the problem the M820 motor ,so they will try to solve based on the problem, just like the noise, or othe problem,I assembled the bike a few days ago and did the first shakedown run on the trails:
- through headset cable routing is really really annoying. I have 5 cables going through it, and it was a pain to squeeze the cables to the side and install the fork.
-there is not a lot of space for the cables just above the motor. I had to tape some to the side, so I was not pinching them too hard with the motor. I was still required to push the motor quite hard into the frame to squeeze the cables a bit. I use a full-length sleeve for the cables, to dampen the rattling noise. I am sure, that this didn't help in this case.
- I didn't want to use the spoke magnete, that came with the motor. I use the Sigma Sport one instead. I had to space out the sensor a bit(because the magnet is not that strong), so it looks quite janky, but I prefer this to the included magnet:

After all this, the bike works!
I set the speed limit with BESST tol to 32km/h for now.
Did the first run of 20km and 400m of elevation. On the flats I used eco, and on the hills, I mostly used sport (middle one).
I finished the ride with the indicated 69% battery left.
This is my first eMTB, so I can't compare it to other offerings on the market. But I can compare it to the TSDZ2 converted city/gravel bike that I use quite a lot.
Compared to the TSDZ2, the optimal cadence range is quite different. TSDZ2 feels like it has a lot of low-speed grunt, but at cca 80 crank RPM, it is completely out of puff. OSFW improves it quite a bit, but it is still not for higher cadences. It really is not for "sport riding" but for commuting, it is great.
M820 comparatively has lower torque at lower cadences, but I didn't manage to "spin it out", or find the high cadence limit. I believe this is much better, for actual mtb. The FW could be improved a bit, though. It feels like the torque sensor input has a bit of limited range, so you too quickly reach full power in a given mode. Will have to do more riding to confirm it.
Motor noise at lower cadences is not that loud, but at higher ones, it is quite pronounced. Even with the slim downtube, you are not fooling anyone, you are on the "normal bike" at this point.
Riding on the speed limit is implemented quite well. There is no jerkiness. The motor smoothly completes your power input, so the total required output power is just enough to ride at the limit.
On the downs, my motor has a loud and annoying rattle. When I was ordering, I was under the impression that these motors are quiet on the downs. I purposely went for DT350 hubs, with low POE number, because on the trail hubs are very quiet. But my motor isn't.
As for the whole bike, I didn't push it too hard, have to get used to to it. As far as the ride itself, I was quite surprised how a "few kg" from my normal MTB changed the ride. It is cca 5kg heavier. It feels much more planted and stable. Suspension is performing a bit better(less feedback to hands and feet), due to the higher sprung weight. Direction changes require a bit more effort. And bunny hopping is quite a bit harder. Will have to get used to this, and to some purposeful training.
Will report back, after a few more rides.
I guess @Rob Rides EMTB will do it soon!
I decided to empty the battery, that was left from yesterday. I used same modes, eco on flats and sport on the climbs.Another ride today.
28km and 750m of elevation. I started with 100% and at the end it was at 40% battery. 95% of the climbing was in "sport" mode, middle one. On the flats it was eco.
Still rattles, and still whiney on the ups. but it looks like I am geting used to it.
I have some problems with the headset, that came with the bike. Even tough it is properly set up, it is a creaky mofo..
I don't know it is related to actual headset of to the inmolded headset bearing cups in the frame.
I ordered another one, to see if it will improve:
Deda S-DCR 1.5 45x45º integrated headset, Black | Bikeinn
Get Deda S-DCR 1.5 45x45º in Black for 54.49 €. Ideal for bike with fast delivery. Buy Headsets at Bikeinn!www.tradeinn.com
Otherwise, bike rides great!
About the head set, is there any suggestions or feedback about it？Except it's too crowded to pass five cables, Maybe it would be better to use external routing instead?
I wasn’t against headset routing until I tried it
Yeah, I meant internal routing but not through headset, theough a dediacted cable port!yes, but it is so ugly
Yeah we need an adaptive mode such as the emtb on Bosch
Yea, that would be the best. But even without it, I believe it could still be much better
