Rather late to the party here, but just wanted to relate my experiences. I have an Aventon Level 3 step through e-bike. It's the first and only e-bike that I have ever owned, so I don't have lots of experience with e-bikes to draw from. I have ridden non e-bikes for years, and have lots of miles under my belt.

My Aventon Level 3 has been a very good performer in the 2 months that I have owned it. I have almost 500 miles on it, and ride it every day. I live in Amish country in Pennsylvania and ride mostly on paved country roads and the occasional rails to trails.

My level 3 has many great features, but also many features that (due to my age and riding location) I will never use. I like the Aventon APP, and have increased my top speed to 28 Mph, but I will probably never use the Geofencing or the rear hub lock. The battery on this bike does not release with a key, but by navigating through the screen interface and pushing an unlock button in a sub menu. I'm not sure how you would remove the battery if you were out of charge and a charger and outlet were not handy. I do like the torque sensor and find it very comfortable to ride for a 68 year old man. It does weigh about 62 lbs.

My final thought are that I really like this bike and have not found any show stoppers. I ride it every day that the weather allows and usually ride a circuit of 13 to 16 miles.

Hope this is of some use.
