The mid-drive gives a more natural, more refined pedaling experience. The Ultro mid-drive series also facilitates some of our newest tech, such as E-Shift and AutoShift, which when combined with Auto Mode, creates a seamless ride experience.
The Ultro S is our 100Nm mid-drive motor, with enough power to propel you through city streets and urban climbs. The Ultro X is tailored for eMTB specifically, and has features that would be unnecessary on a platform like the Level.
The best way to dial in AutoShift is to continue to explore the settings in the app and on the display. Although default cadence is 60, some more experienced riders may find that they prefer a higher cadence.
Level 4 ADV comes in four sizes (S-XL). Please refer to our sizing chart to find which bike fits you best.
Yes, you can purchase a throttle from Aventon and install it on the Level 4 ADV, converting it to a Class 2 ebike. Please note that the throttle response on a mid-drive bike is a much different experience and will feel much more sluggish than a regular hub-drive throttle.
Level 4 ADV comes out of the box as a Class 1 eBike, meaning no throttle and a max pedal assist speed of 20mph. However, the Level 4 ADV is throttle-compatible and able to be unlocked to a pedal assist speed of 28mph.
Aventon does not sell conversion kits. All Aventon bikes are already designed with electrical components, such as integrated batteries, motors, and sensors for an optimal riding experience.
Taking care of your ebike battery is an integral part of getting the most out of your Aventon ebike. Here are a few things to remember:
- 1. Charge your battery regularly to avoid fully draining your battery’s stored energy or voltage.
- 2. Use the right charger. Only use an Aventon branded and proper model charger (Be sure to place the charger brick on a flat, non-flammable surface like metal or concrete. The charger brick will conduct heat while charging.)
- 3. Avoid overcharging your ebike.
- 4. Avoid extreme temperatures. Store and charge the battery in a climate-controlled area, keeping it away from both extreme heat and cold.
- 5. Maintain the right level of charge. The battery should be stored at 75% charge to its health.
- 6. Avoid heavy loads. Do not exceed the bike’s recommended maximum capacity.
- 7. Keep your battery, terminal, & ports clean.
Some Aventon models, such as the Level 2, Level 3, Abounds, Sinch 2, & Aventure 2, come with pre-installed fenders and a rear rack. Additional accessories are available for purchase. Explore a wide-range of Aventon accessories, including helmets, locks, bike pumps, and so much more to add to your next riding adventure.
All Aventon-branded frames, framesets, components, and batteries come with a 2-year warranty. Learn more about the Aventon warranty.
Electric bikes require regular maintenance tune-ups similar to traditional bikes and cars. To get the best performance out of your ebike, regularly check tires, tubes, chains, battery, and brakes, or visit a local bike shop for professional assistance. Performing a pre-ride safety check helps maintain your ebike, as well as staying up-to-date on non-electric component maintenance and repairs.
The torque sensor design is more intuitive for the rider at high and low speeds, it’s more efficient, has smoother power delivery, and is less prone to damage as the sensor is internal opposed to the external cadence sensor.
*Aventon has the right without notice to the consumer to substitute components of at least equal quality for advertised Aventon ebike components in the event of the unavailability of such advertised components. More info.
**Max range is estimated based on a rider weighing 165 lbs (75 kg) on a paved, flat road, in Eco Mode, with Ride Tune set to the default settings. Actual range will vary depending on rider weight, terrain, weather conditions, tire pressure, and cadence.
†Certain features of this electric bike require a 4G data connection. A complimentary 4G connection subscription is included for the first year, beginning from the product service registration date. The 4G connection subscription service enables seamless access to advanced connectivity features including, but not limited to: GPS Location, 4G cellular communication activation, 4G cellular communication, Lost bike reporting, Remote Shutdown, Periodic status reports, Riding statistics summary information, Alarm and operation prompt sound, Vibration monitoring when powered off, Periodic status reporting when powered off, Transportation Mode, Key information synchronization, and Geofencing. After the first year, a paid 4G connection subscription will be required to maintain access to these services. Please note that data subscription fees and terms may apply.

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.
Thank you so much for taking the time to leave such a detailed and positive review for our Level 4 ADV ebike! We are thrilled to hear that you have been enjoying your previous Level 1 model and that the upgrade to the Level 4 ADV was well worth the wait. We are also glad to hear you are enjoying the new features of the Mid-drive. We appreciate your feedback on the small quibbles and will definitely take them into consideration for future releases. Thank you for choosing Aventon and we look forward to providing you with exceptional value, quality, and service in the future. Happy riding!

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.
Hi there,
Thank you for taking the time to update your review for the Level.2 Ebike. We are thrilled to hear that you are enjoying the advanced electronics and features, such as the torque sensor, theft deterrence, and integrated lighting!
We apologize for the issue with the rear rack rails not being compatible with certain panniers, and we have shared this feedback with our product team for future consideration. Regarding the saddle and suspension seatpost, we appreciate your input and will keep it in mind for future improvements as well.
Thank you for choosing Aventon, and we hope you continue to have many enjoyable rides. Happy cycling!
Best,
Aventon

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!!
