Overview of Specs and Components
Frame and Design
The Aventon Abound SR (short-rack) is a testament to Aventon’s commitment to delivering high-quality ebikes with a premium aesthetic. The frame showcases smooth welds that give it a sleek, seamless appearance, reminiscent of higher-end models.
Available Colors:
- Stealth (Matte Black): A classic choice that exudes sophistication and blends seamlessly in urban environments.
- Haze (Purple): A vibrant hue that stands out, perfect for riders looking to make a statement.
- Cobalt (Blue): A striking blue that combines modern style with a touch of boldness.
Designed with a low-step frame, the Abound SR is accessible to a wide range of riders. The adjustable seat height accommodates riders from approximately 4’11” to 6’3″. The standover height is 15.5 inches, making mounting and dismounting easy, especially for shorter riders. However, riders over 6’0″ may find the seat post doesn’t extend quite high enough for optimal leg extension, which could impact comfort on longer rides.
The adjustable stem allows for customization of handlebar height and reach, though adjustments require tools. The BMX-style handlebars can be adjusted forward or backward, accommodating various rider preferences.
Utility and Cargo Capacity:
As a utility ebike, the Abound SR strikes a balance between cargo-carrying capability and nimble handling. It’s perfect for urban commuters who need the versatility to carry groceries, gear, or even a passenger.
- Total Payload Capacity: 440 lbs
- Rear Rack Capacity: 140 lbs
- Optional Front Rack Capacity: 33 lbs
The substantial payload capacity makes it suitable for a variety of uses, from running errands to weekend adventures. The rear rack is sturdy and well-integrated into the frame. While it’s capable of carrying significant weight, it’s important to note that carrying two full-sized adults may exceed the rack’s capacity.
Motor and Battery
Despite featuring a 36V system—which is less common in high-performance ebikes—the Abound SR delivers impressive power and responsiveness, thanks to its efficient motor and torque sensor combination.
- Motor: 750W (Nominal), 950W (Peak) Rear Hub Motor with 80Nm Torque
- Battery: 36V, 20Ah (720Wh) removable lithium-ion battery
- Range: Up to 60 miles under ideal conditions
- Battery Access: Top-loaded for easy removal and charging
- Charging Time: Approximately 5 hours with a 4 Amp fast charger
- Certifications: UL2271 (Battery), UL2849 (Electronics)
The 80Nm of torque provides strong acceleration and hill-climbing ability, outperforming expectations for a 36V setup. The battery is conveniently accessed from the top of the frame. To remove it, you unlock it through the display settings and press the power button, which releases the battery—a unique but slightly cumbersome process compared to traditional key mechanisms.
Drivetrain and Brakes
The Aventon Abound SR is equipped with reliable components that ensure a smooth and safe riding experience.
- Gearing: Shimano Altus 8-Speed Drivetrain
- Rear Cassette: 12-32T
- Front Chainring: 52T
- Shifter: Shimano Rapid Fire Plus Trigger Shifter
- Brakes: Tektro Hydraulic Disc Brakes
- Front Rotor: 180mm
- Rear Rotor: 203mm (hidden behind wheel skirt and frame)
The Shimano Altus drivetrain offers precise shifting and a suitable gear range for various terrains. The Tektro hydraulic disc brakes provide excellent stopping power, essential for a utility ebike that may carry heavy loads. The larger 203mm rear rotor enhances braking performance, especially when the bike is loaded. This is something we haven’t seen from other brands.
Wheels and Tires
- Wheel Size: 20-inch double-wall alloy rims with a thru-axle front wheel
- Tires: 20″ x 3″ Innova Street Tread Tires with Reflective Sidewalls
The smaller wheel size contributes to nimble handling and a lower standover height. The 3-inch wide tires provide stability and comfort, absorbing minor road imperfections. Reflective sidewalls enhance visibility during low-light conditions.
Suspension
- Front Fork: Aventon-branded Trama suspension fork
- Travel: 50mm
- Adjustments: Preload adjustment on the left, lockout on the right
The inclusion of a suspension fork is a notable feature, absorbing bumps and improving ride comfort over varied terrain.
Handlebar and Stem
- Handlebar: BMX-style handlebars with ergonomic locking grips
- Stem: Adjustable quill stem (requires tools for adjustment)
The handlebars offer an upright riding position, reducing strain on the back and shoulders. The adjustable stem allows riders to fine-tune the handlebar height and reach. In their highest position our 6′ tall test rider’s arms were almost parallel to the ground.
Lighting
The Aventon Abound SR features integrated lighting to enhance safety and visibility:
- Front Headlight: A headlamp powered by the main battery illuminates the road ahead for nighttime riding.
- Rear Taillight: The rear light functions as both a taillight and a brake light, brightening when you apply the brakes.
- Turn Signals: Integrated turn signals controlled from the handlebar allow you to signal left and right turns clearly.
Accessories Included
Aventon provides a comprehensive set of accessories that enhance the bike’s functionality right out of the box.
- Rear Rack: Integrated, capable of carrying up to 140 lbs
- Wheel Guards: Protect passengers or cargo from wheel spray and prevent clothing from catching in the spokes
- Fenders: Front and rear full-coverage metal fenders
- Chain Guard: Prevents clothing from snagging
- Dual Kickstand: Provides stability when loading cargo, easy to deploy and retract
- Suspension Seat Post: Enhances comfort on rough terrain
- Selle Royal Saddle: Includes a convenient grab handle
- Bottle Cage Bosses: Two mounting points on the battery for water bottles or locks
While these accessories cover the basics, additional cargo or passenger accessories (like baskets, panniers, child seats, or the optional captain’s chair) are available separately. The suspension seatpost could offer more comfort and performance, especially compared to the premium suspension seatposts available in our accessory store.
Tech Features
One of the standout aspects of the Abound SR is the integration of advanced tech features at an accessible price point.
- Built-in Data Connection: Enables tracking and connectivity features via a $2/month or $20/year subscription (first year included)
- Ride-Tuning Feature: Customize pedal assist levels through the Aventon app
- Display: Small, left-mounted LCD screen with integrated controls
- Connectivity: Bluetooth and 4G LTE for app integration and live tracking
- Turn Signals: Integrated turn signals controlled from the handlebar
- Locking Features: Ability to lock the bike’s kickstand and set geofencing through the app
- Security: Set alarms and receive notifications for unauthorized movement
The built-in data connection is particularly valuable for riders concerned about theft, offering peace of mind through tracking capabilities and remote locking features. The ride-tuning feature allows for a personalized riding experience, adjusting settings like acceleration and assist sensitivity.
Ride Experience
Performance and Handling
On the road, the Aventon Abound SR offers a smooth and responsive ride. The torque sensor provides a natural and intuitive pedal-assist experience, matching the motor’s output to your pedaling effort. This results in seamless acceleration and a ride feel that more closely mimics a traditional bicycle. The Abound SR comes shipped with a top speed of 20 mph but can be overridden in the app for speeds up to 25 mph while pedaling.
Despite the 36V system, the motor’s 80Nm of torque delivers robust power. The bike accelerates quickly and maintains speed effortlessly, even when carrying cargo or climbing moderate hills. To maintain higher speeds on hills, riders will need to apply moderate effort to draw additional power from the motor.
The throttle provides immediate power when needed, and reaching the Class 2 top speed of 20 mph is achieved with ease.
Comfort
The bike’s geometry and components are designed with rider comfort in mind.
- Suspension Fork: The 50mm travel fork absorbs bumps, enhancing comfort over uneven terrain.
- Suspension Seat Post: Marginally smooths out the ride, though taller riders may find the seat post doesn’t extend high enough.
- Saddle: The Selle Royal saddle is firm but the grab handle aids in maneuvering the bike. Many riders may prefer to swap this out if they’re planning for longer rides.
- Ergonomic Grips: Locking grips provide comfort and reduce hand fatigue.
- Dual Kickstand: Offers stability on various terrain especially while loaded. Please note that most manufacturers advise against loading an ebike while the kickstand is down.
Pedals
One area for improvement is the inclusion of plastic pedals. For a bike with a premium feel, upgrading to alloy pedals would enhance durability.
Battery Access and Usability
The battery’s top-loading design is convenient, but unlocking it requires navigating through the display settings and pressing the power button. This process can be less intuitive than traditional key locks, especially if the battery is fully drained. There is an emergency release at the bottom of the frame, but it’s not the most user-friendly solution.
