    Bafang M820 Firmware thread

    I've always noticed differences in the firmware using the M820 with a 48V 720V battery. I tested different versions and voltages, 43V and 48V. The noticeable differences in the 43V version show non-linear battery consumption; it stays at 100% for a long time, and by the time it starts to drop...

    A new E-gravel carbon frame set fit for Bafang M820

    My wife thought the M820 was weak, so I changed the firmware to Fake Taxi and she's loving it, especially the support at low and medium cadence.

    new cef55 frame

    Hoje tenho 2 bikes, cef50 e cef55, ambas comprei o kit quadro, motor e bateria. Para o Brasíl o envio é bem demorado, tempo de porto e desembaraço, mas quando estiveres com a bicicleta irás gostar. Importante dizer que o m820 é para assistência leve o que acha ótimo por ainda teres a sensação de...

    I'll check the battery percentage in the fake taxi after riding without recharging the battery, then switch back to the Bafang 48V version to see if the percentage values change.

    Initial firmware "FAKE TAXI 20260210e1" review: My wife liked the immediate power delivery of this version, which will help her on climbs with low cadence. Our ride was short due to the rain. In my opinion, I think I'll prefer the other version "FAKE TAXI 20260210f1" with its smoother and more...

    Do you know if the speed limits will change? Update: I installed version "FAKE TAXI 20260210e1" on my wife's bike, and she complains that the motor is too smooth. Tomorrow we'll take it for a ride on the asphalt for a controlled test, and I'll share her impressions afterward.

    Bafang M820 Firmware thread

    I have two 48v M820 bikes, but I have firmware for both 48v and 43v. In the 43v firmware, the power only starts to decrease when the battery reaches an estimated 70%, and the assistance cuts off at 12%. I use the 48v firmware and I use conservative power management.

    Yes. We only added connection ports for external cables; there were no other changes, such as power and torque, which remain the same. :( I believe these cable ends will make assembly easier and prevent damage to a connector during assembly; sometimes the simplest things make all the difference. :)

    I only noticed "PRO" in the text, but I didn't find any difference in the text or body of the engine. I'll ask SZZS about it.

    To change this firmware you will need a new cable (I have the best ones).

    M820 or M510 ?

    My wife (CEF55) and I (CEF50) have different riding styles; she uses Sport+ and Boost, while I use Eco and Trail. Her rides are up to 40km with 600m of elevation gain, while I prefer to do twice that. The other day I rode with the 43v firmware and noticed it heated up a bit more than the 48v for...
