What is a firmware?
Every Ampler has a motor controller – the so-called brain of your bike that provides all the functions of your bike, directing every other part of the electronics system. The motor controller itself is managed by firmware (it’s tech-speak for software that controls hardware).
Like most other software, firmware also requires updating every now and then as we’re aiming at providing you with the best possible ride experience.
Why are there currently changes within the Ampler firmware?
Ampler is in the process of moving to an in-house built connectivity platform, which means new firmware, mobile application and backend systems. In this period of transition, there are bikes that are running the previous firmware and the new one, which means two apps are available simultaneously for some time. Read more about where to download each app and when the new app will be available to you here.
How do I know which firmware-version I have?
If you can only use the previous app (black icon), your bike still has the previous firmware. If you can already use the new app (green icon), your bike has been equipped with new firmware (approx. since 30.08.2021) or has been updated at our workshops.
What are the differences between new and previous firmware?
|New firmware (2.1.6/2.4.1 and higher)||Previous firmware|
|Use of the new app is possible.||Sole use of the previous app is possible.|
|Factory calibration only possible after prior approval through us withing the app.||Factory calibration can be triggered by pressing the button.|
|Lights-only mode can be set by power button & app.||Lights-only mode can only be set through the previous app.|
I have a pre-2019 model, will an update affect the private road mode?
A firmware update has no effect on the bike's speed limit, whether it's a bike sold before 2019 or after.
How do I update the firmware?
If new firmware is available for you, the app will notify you the next time you connect to your Ampler.The update is done via Bluetooth and the internet connection of your smartphone. Before updating the firmware, make sure that the battery level is above 25%.
To update the firmware, bring your smartphone close to the e-bike and preferably close to the Wi-Fi router that your smartphone is connected to.
The update is done via Bluetooth and your phone's internet connection, in two steps. The two steps are almost identical and need to be done in a row. This means that after completing the first update, there will be a second update still available, and you will also need to complete this. The updates should take about a few minutes to complete, depending on your phone's Bluetooth- and data connection.
The files are small (~30kb) so don't worry about the phone's data volume.
|If the update has failed, no need to panic. Just wait 10 minutes and try again. If you continue to have problems, please contact us!|
|If you want to check whether you have the latest version, or have postponed your update, open the settings in the app via the cog on the top right of your dashboard.|
|The current firmware version is displayed under "System maintenance". The inactive button shows that your firmware does not need to be updated.|
- If you see a yellow exclamation mark in the app menu, please go to the "vehicle" settings and update your firmware. Prior to updating the firmware, make sure the battery level is above 25%. To run through the update, place your phone near the bike and, preferably, next to the WIFI router you are connected to.
