Smart Display Touch

Save your time pressing battery buttons, when you only have to click a display button to control the whole system. It works using a three-way communication between the display, the battery, and the controller. The whole system is put into sleep mode when the bike is not in use. The battery’s sleep mode’s power consumption is close to zero. The system can be restarted at a touch of the display button, up to one year or longer, after entering sleep mode. You are always ready to go. Even if you forget to switch off the display, the whole system will still enter sleep mode after 10 minutes. This is especially favourable for internal tube (in-frame) batteries, which have less convenient to press battery buttons.

This efficiency and power-saving integrated system includes an ebike battery pack, a torque sensor, a display, a controller and an optional eRider app.

Torque Sensor has high precision and quick dynamic response. Display meters come with LCD, TFT, OLED or LED display types with different sizes, and also USB ports. Certain models also include a Bluetooth function, which you can use to connect with our eRider app to check on battery status, riding record, navigation, and much more.
