I've seen it too, but it's probably for the E-road models.

The M 820 is currently only available in 36V and 43V versions. My motor is originally a 36V which my salesman flashed for me with the 43v software on request. I only use the 48V battery to get a little more power out of the motor.

Where did you find the article/photo?

Unfortunately, the E69 frame is locked for free sale. Had talked to Mia from Dengfu at the end of last year and had already made an order for a size M frame. The price was also okay, but then I was told there were only a few in stock and they would get back to me. ??? I haven't heard from Dengfu...

Look here: Carbon Fiber Cranks 165 Q:8 FB Isis Standard (Black) for E-BIKE & MTB & ROAD & TRACK

That means you can already order a frame in size L and just have to wait longer?

@JimLee-Lightcarbon, any news regarding the L-size of the LCE 929 ?

Nice battery design. I can't see any difference to the M 510 in terms of power reaktion. However, I also have the 43V version.

The 48V battery is a 13S with 54.6V end-of-charge voltage, which still works with the 43V version of the M820. However, the 14S battery is a 52V and will only work with a 48V version

My bike with the LCES 004 frame is 6 kg heavier and you can already see that in the handling. Downhill, however, I prefer the extra weight. Since I changed the head angle of the LCES 004, the frames are similar in geometry. I don't think there will be a 48V version for the M820 and a 14S3P...

The 43 V software only goes into surge protection at 55.9 V. So enough room for a 13S battery with 54.6 V end-of-charge voltage

What material did you use to make the mounting plates?

There must still be an intermediate cable

I think a 13S3P with 21700 cells just fits into the frame. That would be 720 Wh. However, the weight of the bike would increase to over 19 kg.

Yesterday I did a tour of 68 km and 1600 hm without using the range extender. However, only in levels 1+2

The engine doesn't get particularly hot. However, I also rarely use level 4 and 5. With the increased voltage, the power is also sufficient in the lower levels. And the first 20km the display remains at 100%

No, I charge it fully and then get 13x 4.2 V = 54.6 V. Then I still have 1V reserve until the overvolt-protection

In fact, I'm still missing the M560 in my collection, not a bad idea 👍
