You can easily control the e-bike on your smartphone with the app BitRide. With this bluetooth app you can 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 complete dashboard of your e-bike.
As an extra option you can mount a wireless remote control by Zehus on the handlebar. With this you can select and change your support mode while riding, keep an eye on the charge percentage of the battery or use it as a speedo. It's useful when you rather don't want to use your phone while cycling.
