As a Swiss e-bike pioneer, we at FLYER develop our own drive systems, which we call FIT – FLYER Intelligent Technology. The three-and-a-half inch FIT D1 display is your perfect training partner. The fitness screen shows not just your personal performance in watts as well as your pedal frequency and energy consumption, it can also show your heart rate. Connect your e-bike to a compatible Bluetooth heart rate monitor. Move the joystick all the way to the right to navigate to the settings. You will find the Pulse function in the Connections submenu. Activate this function. Now FIT automatically searches for the nearest heart rate belt and pairs with it. In Fitness mode, you can see your heart rate in the middle of the screen. We wish you lots of fun and great rides on your FLYER e-bike with FIT.
