QiCycle - Increase the limit to 29km / h with a custom firmware

If you are a lucky owner of the Mijia QiCycle EF1, Xiaomi's pedal assisted bicycle, you will have surely noticed that with the stock firmware the electrical assistance stops intervening at 20km / h (limit imposed in China). With the app International QiCycle, depending on the model, it is possible to bring this limit to 25km / h via a software update.

Unfortunately, not all models (including mine) have received this update, but it is now possible to force the installation or even use a custom firmware to bring the speed limit to 29km / h through the application created by Christopher

The procedure we are going to use, although personally tested, uses unofficial tools and a custom firmware. XiaomiToday.it is not responsible for any damages arising.

As with any update operation, we recommend that you have the devices (telephone and bicycle) fully loaded. Furthermore before performing the procedure we advise you to read the whole guide.

1

Installation and configuration of the QiCycle application

  1. Download from the Playstore and install theQiCycle application of Christopher.
  2. Associate your Google account from the menu at the top left and click on "Click to access"
  3. Associate your QiCycle with the + button and frame the QrCode of your bike

2

Firmware selection

In the field Motor, the central value of the string shows the version number. The firmware limited to 20km / h is the 015. It is possible to install the Custom MC 019 to bring the limit to 29km / h or alternatively use the official 017 firmware to bring the limit to 25km / h.

  1. Go to the "Other" screen
  2. Click on the blue button with the arrows at the bottom right
  3. Select the category on the left Custom MC
  4. Select the file on the right side MC_005019000_CF.bin

3

Firmware installation

  1. Confirm the installation by clicking on "Accept"
  2. Click on the circular button at the bottom right (arrow up)
  3. Confirm the update again
  4. It will now start sending the file to the bicycle. Keep the phone near this.
  5. A message will confirm the successful transmission of the file

4

Updating the QiCicle

  1. Confirm the update by clicking on the UP arrow
  2. During the update there is no progress indicator but only a warning screen. Wait for (about 5 minutes) to disappear and the software will reboot.

5

Go out and go and humiliate the Scooters at the lights

The 019 version reaches the 29km / h only with the battery charged. As the charge decreases, the limit is lowered as well. The 017 version (limit to 25km / h) suffers from the same problem but less.

Finaly got round to giving it another go. I installed the 017 with the best problem in power I know what the heck I'll go for the 019 which again insalled no problem at all. I can now achieve 27kmh with only 50% battery. I know now it's time to stick it on and then try again. Thanks again for the guide to Christopher who developed the app. AAA +

when I click on the button on the bottom right (after connecting the bike with the QR, and with everything seemingly working) instead of giving me the opportunity to install the custom firmware, it tells me:

Info
You must be identified and connected to the server

what do you have to do in this case?

Hi, I did not understand. But does the firmware also translate the language of the computer into English?

What to do now? We are logged in with Google account and connected to the bike.

Hola, the aplicación ya no funciona, if I eliminated of the google y market for aquellos que, como yo, tenían instalado, the firmware flash ya no es posible (servidores inalcanzables). ¿Cuál es la preocupación? ¿Will I go? Cuanto tiempo agradeces

Buenas. Actualicé a versión custom porque no leía that the people ya se quejase of the problem de batería y luces. However, if you have quedado a 000000000 y La Luz trasera sin lucir. ¿Hay solución? Porque actualizo BMS y como quien oye llover.

Thank you very much

Actualicé to this verse y mejoró considerably the speed of my Qicycle, I unan 15 min antes recorrios unos 11 kms to mi trabajo, sin embargo ..., if desconfiguró el indicador de batería en the pantalla led (so puedo revisar si está cargada the batería with el medidor que está in the base de la batería) y luz trasera no funciona (será comprar an externa) digo estas soluciones porque honestly me dejó to taste el that increases between 4 y 5 kms / h la velocidad, antes sentía la restricción de 21 kms / h in las piernas, y ahora con nada de esuerzo...
