The Strada Smart connects with your smartphone through the CatEye Cycling App. The Strada Smart is mounted on your handlebar or stem, while the smartphone is stashed out of harms way in a pocket or saddle bag. In Mirror mode, the smartphone records ride data and transmits a copy to the Strada Smart. Phone call and email alert icons are also displayed. The phone is kept in sleep mode, preserving the battery. The Strada Smart can work with Bluetooth Smart Speed, Cadence, Heart Rate and Power sensors in this mode. When smartphone use is not an option, Sensor Direct mode can be used as a back up. Sensor Direct mode syncs the Strada Smart directly with the Bluetooth Smart Speed, Cadence, Heart Rate and Power sensors, so important ride data is always available.
