"Smart" features can sound vague unless you look at what they actually do. On The ADO Air Carbon Pro, NFC has a fairly specific purpose.
The bike has NFC power on/off functionality, and the manufacturer states that the tap-and-go process takes around 1.7 seconds. Instead of relying only on a conventional button, the system allows the bike to be powered on or off through NFC.
The digital system extends beyond starting the bike. The ADO App can record rides in real time and track statistics, while navigation directions can be cast to the integrated LCD display.
There is also built-in GPS functionality described as part of the bike's anti-theft system.
These features don't replace the basic bicycle components. The Air Carbon Pro still uses hydraulic disc brakes, built-in lighting, a carbon belt drive and a BAFANG motor with 50N·m of torque.
Looking at each function separately makes the technology easier to understand. NFC deals with access, GPS relates to security, and the app focuses on ride information and navigation. That is more useful than simply describing the bike as "smart."
