Mobile App for e-bikes

As a passionate cyclist looking to make the move to e-bikes, I need an app that provides great battery monitoring and is compatible with both iOS and Android. The app should be able to monitor the battery level while also providing detailed ride statistics. Although I don’t have a specific design or branding I'm looking for, I'm open to fresh ideas and designs as well as suggestions for visual elements or for a user experience that can create a memorable and lasting impression.
GPS navigation and fitness statistics as well.
