ADO Air 20 eBike review: A fun & agile foldable city bike with belt drive

The display is in color and is IPX7 certified, meaning it is waterproof. You can see everything important at a glance, so you don’t have to click through a bunch of menus – very good! Next to an (if a bit rudimentary) battery display, it also shows the speed, support mode, trip distance, total distance, light and Bluetooth status, and possible faults.

Thankfully, the total distance is even saved when the battery is empty. There is even a USB-A port on the bottom of the bike, which you can use to connect your smartphone, for example.

In terms of display functions, the manual is unfortunately very minimalistic – for example, we couldn’t even find out how to switch the light on (press and hold “+”). It also doesn’t mention anything about the menu (press and hold “+” and “-” together): Here, you can choose to show 5 instead of 3 support modes, change the language and background light, and much more.
