Zehus is a self-regenerating Italian engine "all in one" that looks great on a minimalist bike like Veli

The app that runs the system is called Bitride and is available for iOS and Android. You have 6 riding modes to choose. In addition you can regulate Kers which by creating more friction, regenerates more battery power (eg downhill) With some skill it can take weeks without charging the battery.

You can also check the distance, speed and so on.
