Why QA for connected micromobility needs to be rethought
E-bikes have long been more than just bicycles with electric assistance. Modern drive systems consist of complex firmware, sensor technology, Bluetooth interfaces and a mobile app, which is becoming the central control center for many users. Navigation, ride data, battery status or connections to platforms such as Strava: today, all of this runs on the software side - and must function seamlessly.
This is precisely where the challenge lies: How do you test e-bike software that is embedded, mobile and connected at the same time? And how can quality assurance keep pace when development cycles are becoming ever shorter and releases ever more frequent?
From mechanics to software: How QA is playing a key role in the e-bike sector
What used to be solved mechanically now depends on firmware and code. A sudden Bluetooth failure, incorrect performance data or an app that does not start on an Android device - these are not marginal problems, but potential purchase criteria.
In this area of tension, QA today has to do more than classic tests at the end of the cycle. It needs:
 Agile, continuous test processes
Test environments with hardware-in-the-loop
Simulation options for driving data and sensor states
Automated re-tests for app and firmware updates
Test plans that map user stories and real usage

Special challenges when testing e-bike systems
|
Quality assurance in micromobility differs significantly from classic app testing:
App, firmware & hardware interlock
A bug in the app can affect the interaction with the motor control unit. Conversely, firmware changes can cause unpredictable app behavior.
 Variety of test constellations
Android vs. iOS, different Bluetooth chips, different user behavior - all this has to be tested.
 Regulation
In Europe, standards such as EN 15194 apply to e-bike systems, which concern functions such as assistance behavior or safety shutdowns - and are therefore also relevant to software.

Best Practices for e-Bike Software QA
The following strategies have proven effective in ensuring that quality assurance for e-bike systems is efficient and effective:
Integrate test early (“Shift Left QA”)
Matching test cases to real use
Simulation instead of continuous field tests
Test automation for recurring processes
Transparent QA budgeting with regular tracking
Conclusion: Quality assurance as the key to smart mobility
In connected mobility, reliability is a selling point. An e-bike app that charges quickly, navigates reliably, integrates all sensors properly and works seamlessly with third-party providers creates trust - and stands out on the market.
From established manufacturers such as Brose to young mobility start-ups, quality assurance for e-bike software is no longer an add-on, but part of the product. If you want to survive in today's competitive environment, you have to be agile, realistic and forward-looking in your testing.
