Riding an electric bike without a display: is that possible?
The answer is “Yes, but not yet as good as it could be”.
In more detail, this means that most modern e-bikes have a Bluetooth interface that allows you to connect your smartphone to the bike. In addition, more and more e-bike manufacturers offer their own apps that you can use to access your bike and, for example, change the support. A traditional display with a large screen is then not necessary anymore.
And is it not the case that your smartphone is the more powerful bike computer anyway?
Unfortunately, mobile phones can’t yet really make the most of their possibilities as e-bike control centres. This is primarily due to the fact that the apps of most manufacturers don’t work well enough. Since there are no interfaces for developers of third-party apps, the alternatives are also often lacking.
