Aventon: Level 4 ADV Step Through

Aventon Level 4 ADV Step Through

The Aventon Level 4 ADV Step-Through, offered by Bike Attack, is a mid drive powered top-tier commuter e-bike with easy access step thru frame that is designed for riders who want a blend of comfort, performance, long-distance capability, and smart features in a polished package. It is built for city travel, everyday commuting, recreational path riding, and occasional light mixed-surface use.

A Step-Over version is also available, along with the rear-hub variant, the Level 4 REC.

Positioned as the most advanced bike in Aventon’s Level series, the Level 4 ADV is intended to make commuting easier, more connected, and more refined. With commuter-ready accessories, integrated technology, and a high-end mid-drive system, it suits riders who want a reliable e-bike with modern connectivity and utility.

Smart commuter performance

The bike is powered by the Aventon Ultro S mid-drive motor, which delivers up to 100Nm of torque and 750W peak output. This setup provides quick acceleration, a smoother pedaling feel, and strong climbing support. Whether riding on streets, through neighborhoods, or along designated bike routes, it offers controlled handling and balanced assistance across varied urban conditions.

Its claimed range reaches up to 110 miles, making it suitable for longer commutes, extended leisure rides, or full-day outings. Riders seeking a premium long-range commuter with integrated technology may find this model especially appealing.

Electronic shifting and AutoShift

The Level 4 ADV uses a Shimano CUES 10-speed drivetrain together with Aventon’s E-Shift and AutoShiftsystems. These features can automatically manage gear changes based on cadence and speed, helping riders stay in an efficient gear without having to shift manually as often. The result is a ride experience that feels more seamless and less distracting.

For anyone looking for a commuter e-bike with smoother, more intuitive gear management, this represents a meaningful convenience upgrade and a comfortable step thru frame.

Integrated ACU smart technology

The bike is equipped with Aventon ACU smart functionality, giving riders access to connected features intended to improve both safety and customization. These include:

• GPS location tracking
• smart security features
• adjustable ride data and settings
• Ride Tune customization
• Auto Mode support

Together, these elements make the Level 4 ADV a highly connected commuter bike that emphasizes both rider confidence and personalization.

Practical commuter setup

The Level 4 ADV is built with daily use in mind and comes standard with several useful commuter components:

• rear cargo rack
• full fenders
• integrated front and rear lighting

These additions make it easier to carry items, handle changing road conditions, and remain visible in lower light. From weekday transportation to casual weekend riding, the bike is designed to be versatile and practical.
