Exactly what I wanted
Arrived quicker than I expected and the build feels solid. I use it for a short commute and the battery still has plenty left at the end of the week.

Easy to live with
Setup took about twenty minutes and the instructions were clear. The seat adjusts far enough for both me and my partner to ride it.

Great value
Comparable bikes cost a lot more. Packaging was good, nothing was damaged, and support replied the same day when I asked about the charger.

Handles rough roads well
The fat tires and suspension make a real difference on broken pavement. It is heavy to lift, which is my only note.
