Before the first ride on a Ninebot One Electric Unicycle

-Charge battery: Red light = effective charging, green light = completed charging
-Place protection foam stickers, (protect the Ninebot One but also your legs in the beginning; place it where your ankles touch the wheel)

-Inflate tires (works at most gas stations without any valve extension) (CST Cheng Shin Tire) says 40-50psi/2.8-3.5bar
-Apply grip tape to foot rests
-install app, check speed limiter
-wear protection, use lights.

Inflating the tyres on the other hand, really is a hassle. Even with the extender it is difficult. For me, personally, it is the only design flaw in this euc. That is to put it politely. You can have a look here:
