oh my word ..this 20.8 fw is a GEM. This is what I have been waiting for after trying all the fw from 46.7, 46.8 and 14.6. The power distribution is similar to 46.8 drawing about 4A at PAS1/9. No brutal ramp up of 10A as detected in 46.8. It has a slight ramp, I believe about 5-6A just sufficient for a slight push when stomping the pedal. Range is marvelous possibly better than 46.8 as there is no overun when pedalling is stopped. This is very usable for technical trails with roots, ruts and severe undulation. No sudden lunging or wheelie when press hard duri ng pedalling transition. I would urge those who does hardcore technical riding to upload 20.8 on your M600. It will probably give the M510/M500 13A or possibly the latest Bosch a run for its money. Sadly, this will not be suitable if your rides are mostly fireroad, tarmac, commuting, pulling a sledge, touring and other similar mild terrain. Use 46.7 instead.

20.8? How is it at higher pass levels? Anny info about the annoying battery saving at low battery percentages?

As I have said, I only use the bike for technical rides..which means staying at either Pas 1 or 2. Anything beyond is unrideable. As for low battery attenuation, I haven't taken it that far before as range is not important to me. I only ride a max 20-25km per ride. Perhaps you can try it out yourself.

A question about m500 firmware: what is the difference between the two 10A firmware(2015.5 VS 2050.6). The first one is stock and feels kind of sluggish.. How does the other one compare to it? Currently using 12A and I like the snappiness of it(comparing to 13a) but I would like level1 to be more power efficient - sometimes doing really long rides...

You have a problem with hosts file. Be sure, that your windows hosts file (located in System32/drivers/etc/hosts (not hosts.txt - typical error!!!) must reply to

ping test.api.besst.bafang-service.com with 127.0.0.1 which is localloop, not with bagang IP!

this is how it should look like

I can fix it remotely if you cannot, but it will cost you a beer...just sent me meeting id and i can have a look.

record in hosts file (not hosts.txt, just hosts) should look like this

127.0.0.1 test.api.besst.bafang-service.com
hi any chance you could do a video on how to do this as im struggling willing to pay

Hello,
please could someone expain to me how does the version naming works?

For eample in GitHub I see this firmware:

CRX10NC3615i142059.6-28-2230-20201218.bin
If I try to split the name into fragments:

CRX10NC - some commont prefix
36 - volts
15 - amps
i142059 - ? (maybe needs to be split more)
.6 -?
-28 -?
-2230 - ?
-20201218 - date of release

Does enybody understand to that unknown fragments?

Currently in bike I'm using version CRX10NC3615i142017.7.
My question is if my current version is odler or newer than CRX10NC3615i142059.6-28-2230-20201218.bin?

(does enybody know where I could download my current firmware - CRX10NC3615i142017.7 - to have a backup?)

Thank , Petr

.. fully charged 36v battery is about 42v... so 42*20... 840W - so it was probably not 850W peak.. something aroud 840-850W (i have DC241 display and it is hard to read it on the sun ;) )

Ok, so we did about 25km today and I must say that the bike is much more powerful! I love it! Max peak was really about 840W! The feeling is now very similar to Yamaha that I use to have!
What is really strange, is that I had almost the same battery consumption as my wife with stock 15A firmware ( the same bike, the same M500, even though my wife is 30kg lighter than me). When we got home I had 78% battery left, my wife had 79% of battery left! That is pretty cool. I was very afraid that the consumption will be increased significantly, but no!
Tomorrow I will have to upgrade my wife's bike as she was angry that she couldn't chase me 😂.

Correction - that math is not correct. You need to distract voltage sag cca 3V to 4V and for 15A controller ovetshooting to 20A is too much.

So it is more like 38.5x18 = 693W

Anyway there exist 36V and 17A firmware for M500.

I've just broken the handlebar strap on my DP241 display. I think its a common break and someway back in one of the threads was a repair for it, can anyone remember where or what it was. Thanks

Attaching M600 firmware 43V 25A - up to 1300W with 48V battery!!!

->Be careful it is overheating, when u hold full throttle for few mins.
->Throttle has 1s delay when u not pedalling (Bafang what are you doing there!? Was it a purpose? )
->At 20% it shut down and then when I power on motor again it was showing only 1%. (Could be either motor went hard cut off or my battery BMS triped - with no load I measured 39V ) - which is good, as you would drain battery till the end.
