Dear Bafang fans

Also can download motor firmware for M500, M510 and M600 motors and run Calibration.


Tested on M500, M600 rev.A and B, M510 FC1.0 and FC2.0 so far. In the future also support for M620, M630, M560, M420, M300.
Speed unlock, circumference, wheel supported by all Bafang CAN motors, including CAN hub motors.

K1 Flash Lite starting from 130 Eur including shipping.

Maybe I'm missing something. Not seeing the big deal here. This ability has been around a while now....

What might help make it a bigger deal is more info, with some specifics regarding "included SD card (with set of firmwares - cca 50 firmwares".
What exactly can one expect with each of these "firmwares" as compared to OEM programing?

Did you go through the google forms link? There is explained everything.

And advantages:
- No need to get BESST, passwords to Besst (which expiring), no need to connect to computer and u can flash firmware and set parameters even on a street or during ride when u searching your power setup.
- No need to search for a firmwares on forums. Time is money.
- Simple firmware flash also for non skilled people - just insert included SD card, power up K1 Flash over USB-C and connect CAN connector - device will automatically select firmware from card according the motor type.
- You can set speed limits as u want. With Besst it is now disabled - I can set only 27kmh over Besst. Also other advanced power parameters (M510, M560)
- Calibration run - when u replaced controller.
- Also great for ebike shops - you can flash firmware, set config parameters and run Calibration in one go. You are done in one minute. You can have more SD cards for different motors and setups.

Not gonna explaining you differences between firmwares. There is a lot of differences in behaviour and setup.

If you wanna criticise, and you think no big deal here, just leave it and buy BESST.

And also second device: K1 BlackBox3.

Device which can be cabled permanently on an ebike and you can switch between speed limits any time by holding Plus button. Also to set all other possible parameters.
Or you can set controller parameters and deinstall BB3 from ebike.
Waterproof and no need external power.

I wasn't aware that the ability to change more than tire size and max speed was easily accessed by end users.
This seems to allow for a lot more.

There is this abbility for a year now. So far only M510 is supporting it and already saw one Bafang HUB CAN controller which was also able to set power levels. In the near future also M560 and M630 wil suport this.

And all Bafang users are waiting for Bafang Go App, where this power levels should be also adjustable over BT. Just it is taking too long for Bafang - their app is a crap.

Like what? What are you seeing? The ability to install firmware with unknown changes?

I'm failing to see the need for this tool OR the BEST tool.

I was going by the parameters seen in this screenshot.

Not saying anything more than interesting and there seems to be some progress in cracking CANBUS

I'll give you "interesting" without argument. It would appear though, that this work applies to just the M510. Don't get me wrong here. You know I'm all for development. I just don't care for folks making/selling vague claims.

 

[K1eBikes]

Now supported also M620 CAN firmware update. And should be working also with M300 and M420 (same bin file type).

 

[K1eBikes]

M620 owners !!!

There is firmware v1.2 (30A) with option to adjust max power at each assistance level!

And brand new 750W (25A) firmware v 12.3 which has same options as M560! So including Assistance level % and Acceleration at each PAS. Worth to try. Check K1 Flash page.

If you own M510 FC2.x or M560 and you wanna get rid of throttle speed limitation , there is brand new BBR Ultimate, just finished testing.

Are you not confident with power limitation at low battery SOC%?
Would you like to set lower discharge cut off voltage to get more range from your battery?
Would you like to remove throttle speed limitation?

Theres a new device BB Racing, whit many new functions. You can set Low Voltage cut-off to 3.0V per cell or even lower. You can use 52V battery with 48V firmware and have accurate SOC % reading.
