I have an Aventon Level 3 commuter bike and I have no complaints about it after riding it 1012 miles so far since April.
I really don't have much to compare it with, since I've only ridden three or four other e-bikes.
Some were more expensive (Specialized mid drive) and some were less so (Dart and small folder).
I like my Level 3, but have no use for all the security features. I live in the country and usually take about three thirty mile rides on country roads in a week. The battery holds up well, and I usually have about 48% charge left after my 30 mile rides. I ride in eco mode, and only use a higher pedal assist on one large hill. Every ride gets a bit easier.
