Kyoku, is there some regulation/law which is telling exactly what voltages can be used for ebikes?

Just received today the M510 ordered to https://fr.mayebikes.com/
they (her, nicole) are really trustworthy. she have difficulty to obtain the motor from bafang, but it doing his best to provide me.
i find the speed sensor magnet on the disq very way than better than on wheel, somebody know where it is possible to ordering this speed sensor ?

Yes.
I installed a rev1 engine. at 38 °C 
with the firmware shared by @Rob Rides EMTB . as far as I have seen it is 48v. I made a circle around the street, and tomorrow there is a long drive. comments after driving. and as for the "52v" firmware, disaster! there are power oscillations when pedaling, when you start it gives a lot of power and after a second it stabilizes to something "normal"! while driving, when you do not turn the pedals and start pedaling again, the same as at the start. @KaroKönig is the same thing happening to you? so does Bafang need 6 months to make a good firmware? it would be time for them to make a stable Firmware for both engine revisions!

Do you think it is safe to use with 48V battery?
I do not know mate, it will rather not break something, in worst case may cut off battery and show incorrect reading or errors.
Yes, maximum voltage in EU for 'pedelec' is 48V.

I tried once on about 40kms ride, very good firmware actually but it will show your battery only 70% in full charge.

Seems to be the best M510 firmware so far, but I'm still afraid to try it with a 48V battery.
So I'm thinking of upgrading my battery to 52V or buying a new 52V battery.

thinking the same
Today I was driving the m510 rev1. and new firmware. for now it is a big improvement, it has more power than the previous FW, there is no more sudden start, you can feel the power when starting, but the delivery is more fluid. pedaling is ok, you can pedal lightly at low cadences and keep the pace, at higher cadences the power delivery is stronger. all in all, a very big improvement compared to previous versions of rev1. and rev2. a little more to improve the torqe sensor and everything is great. I will see on the next rides how it will be, then I will write more.

Do you mean by the new firmware a 52V-firmware?
not rev1. is 48v. it was shared a few days ago by @Rob Rides EMTB

I got lost in the names, do you put the full name/number of the FW please?

Now I understand you are using a 43V FW, is your battery 43V?
I wrote everything a few posts ago, yesterday's post.

Only issue is the 52V is not legal in Europe for road use in pedelecs. Of course if you dont care of this then 52V is only a pure profit. Kyoku, is there some regulation/law which is telling exactly what voltages can be used for ebikes?
www.emtbforums.com
do you read the posts on the forum?

Hello guys. Adding 43V 18A FW v 5.0 (so peak up to 850W ) - have not tested it yet. Edit: Works with "old" motor version (the one where 52V version 3.2 does not work )
www.emtbforums.com
now I wrote to you that the FW is 48v! and on wednesday I posted that it had arrived and that I was using a 52v battery.
sorry, I marked the wrong firmware.I installed a rev1 engine. at 38 °C

M510 48V can fit for another brand battery 48V 21ah , about 1000wh, in fact the Bafang use the same battery box as this brand, cell is 21700. i think it's better than use BT F25 52V

I did'nt get it: Please tell us what firmware you tested and what battery you are using. I was reading the last pages of this hread and to be honest i quite do not understand anymore what the right name of your ifmrware is and if it is working fine or notsorry, I marked the wrong firmware.

Hi all,
how does the Bafang m510 motor compare to the Bosch gen 4, i am considering a custom build Dengfu e10 build to replace my Cube 160 AT any thought would be most helpful.

greeting. I use a 14s4p 21700 cells 52v battery. engine m510, I have rev1 and rev2! firmware rev1 48v last shared by @Rob Rides EMTB works fine for me. firmware rev2 "52v" shared by @Rob Rides EMTB doesn't work well for me. @Puschtrale satisfied?I did'nt get it: Please tell us what firmware you tested and what battery you are using.

Today I tried the following new firmware, the last firmware posted by @Rob Rides EMTB
(CRX10NC4814i101003.0-28-2230-boot3.0-20220628153910.bin)
In fact, I did not notice any difference between it and the firmware we were using before:
(CRX10NC4814i101003-1-cs-28-2230-boot3-0-20220517161110-48v-M510.bin)
As if it was the same?!!
The sensitivity of the pedals themselves has not changed, you still need to put a fairly strong torque on the pedals for the engine to start supporting.

but it is no longer on-off, it can be driven easily at a low cadence. and it seems to me that it gives a little more power and there are no sudden starts.

Honestly, I did not notice that difference, as before when pedaling at a low cadence, the engine does not work.
In my opinion, this is what Bafang is trying to do to reduce power consumption to get longer battery life.
on yesterday's drive, the engine worked great. a couple of times I kind of faltered a little. maybe it's because of the 52v battery, it has higher voltage and more power!? I didn't charge the battery, so I'm going for a drive tomorrow to see how it behaves with low voltage.

Great thread, may I ask a few questions?
- How is the noise on that new M510, are there videos that have a good representation of the sound it makes when riding on a trail?
- Is there a specific 52V version of the motor, or is it just the 48V version run at a higher voltage?
- The M510 is CANBUS only, right?
- Has Bafang ever sorted out the issues with the M500/600 in terms of running as smooth as the main competitors? I have lost track of the recent developments regarding this.

- Engine noise is audible while riding the bike but I find it quite tolerable.
- Engine versions available for sale are: 36V, 43V and 48V. I didn't find a special 52V version.
You can always reprogram the controller to change the voltage by installing a different firmware.
- As far as I know, All M510 engines are CANBUS.
- There are many firmwares for the previous M500 engine. Some of them are very excellent but the M500 engine heats up quickly under pressure. But the M510 engine gives much better support Without getting too hot. Thus, it maintains high performance under pressure for a longer time.
I've never tried the M600 engine and I'm not aware of its problems.
