Pros:
- Displays the speeds.
- The rear light is powerful and easily distinguishable.
- Easy installation on the saddle.

Cons:
- The saddle is somewhat lazy as it easily falls forward.
- The ring that holds the tongue on the handlebar is very cheaply made.
- The manual is an exact copy of Xiaomi's, in other words, it is wrong because it is for a different model.
- The plastic ring in the closing mechanism where the handlebar locks onto the rear wheel also does not seem good.
- Unfortunately, it does not include an extra pair of wheels like Xiaomi does.
- The tube that is an extension of the pump for the front wheel was damaged.
- The rubber band that protects the charging port is not good and is likely to break soon.
- The battery stock displayed on the screen changes according to the speed.
- The button is difficult.

Some extras:
On the screen, there are the letters ECO, D & S.
ECO = 20km/h
D = 25km/h
S = 30km/h
You can change these by pressing the button twice quickly.
If you press the throttle switch all the way, the speed locks until you press it again.

These are not mentioned anywhere when they should be :/
