I purchased the Level 1 five years ago and used the heck out of it. On-road, off-road, even some light trail and mountain biking. It did it all. I've been waiting for a mid-drive torque sensor motor before making the upgrade. The L4 ADV was absolutely worth the wait!

The motor is quiet, shifting is smooth, and the extensive features are excellent. The riding experience is so nice. I thought the auto-shifting would be kind of a gimmick, but I was surprised at how much I like it and how well it works. I removed the fenders & rack so the bike can be a little more trail & dirt compatible. This Level 4 ADV functions exceptionally well as a trail bike, and is of course a fantastic road bike.

If I had any small quibbles, it would be:

1. No quick release for the seat post.
2. Wish there was a simple button combo to reset the Trip time and mileage (instead of going into settings or the app).
3. Wish the Throttle was included in the purchase price, not needing to buy it separately - though it was not expensive and super easy to install. but why not just include in up front?

But none of those small items drop it from being a five star rating. This is an exceptional value when you consider the quality of the components and all of the features included. Well worth the price. But, that's what Aventon does with all of it's bikes... Exceed expectations with value, quality and service.

I've had my Level 4 ADV for three weeks and 280 miles. Here's a few more observations.

1) The electronics are incredible and go way beyond automatic shifting and theft deterrence.
The battery includes temperature limits to prevent charging or discharging outside of a safe range.
It takes about a minute to calibrate the shifting and crank. No more bike stands or time consuming trial and error. After calibration the shifting is smoother than any bike I've ever had.
The pedal response automatically adjusts to the four assist levels. I haven't even touched the shift buttons in three weeks, except once to calibrate the shifting.
Uphill start assist senses when you're on an incline and adds extra power.
Assist profiles can be programmed and saved. It's particularly useful to riders of different skill levels sharing a bike.
The metrics include total calories burned and the amount of CO2 kept out of the atmosphere.
The app has adjustable service intervals that track routine maintenance.
Rides are automatically logged, including the route and numerous metrics, but it starts a new ride every time you stop for a few minutes. Other apps continue recording until you stop them.

2) I live two miles from the General Motors Technical Center and this one is recall-worthy. The rails on the rear rack have a square cross section rather than round like any other racks I've ever seen. I have both Lone Peak and Rock Bros panniers. The Lone Peak panniers keep falling off because the locks on the hooks can't go completely around the rails. The Rock Bros panniers can't be attached at all because the rails aren't wide enough. I can't imagine how the Aventon engineers overlooked this.

3) The stock saddle and suspension seat post are too hard. I weigh 130 lbs., the lowest recommended for the seat post.
Fortunately the Brooks saddle I've had for decades fits on the Level 4.

4) The battery "overcharging" on the Level 2 is not as much of a problem on the Level 4, but you still need to manually calculate the charging time to stay within ideal limits.

5) The handlebars have very little room to add accessories. I've added a second clamp-on bar.

Other than the rack, the Level 4 ADV has exceeded my expectations. I definitely recommend buying one, especially with the price of gas soaring and climate change wreaking havoc on our planet.

Great ride

Level 4 REC Ebike

Picked my bike up 3 days ago and finally have it set in the sweet spot for my range for the bike and I'm very pleased.
My first non big name Ebike and I'm very impressed with the quality, the customer assistance and the app!
Hands down been some of the best in response.
Also the auto shift paired with auto mode my favorite of all. Might not get the full range out of using Auto but I will save the rest on longer rides!!
