You can control the e-bike on your smartphone with the Zehus App. In this bluetooth app you register your e-bike, select your assistant modes, lock or disable the bike and check your bike data. Its user-friendly interface offers you a dashboard of your e-bike. 

You can also mount an optional bluetooth remote control on the handlebar. With it you can select and change your support mode while riding, keep an eye on the battery percentage or use it as a speedo meter.
