The Next Generation of Folding Ebikes
The Aventon – Sinch.2 Ebike is the upgraded second-generation version of Aventon’s popular folding fat-tire ebike. With a more powerful motor, torque sensor, and color display, the Sinch.2 takes portable electric biking to new heights.
Powerful 750W Motor
At the heart of the Sinch.2 is a 750W brushless rear-hub motor that delivers exceptional torque. The Aventon – Sinch.2 Ebike accelerates powerfully up to 20 mph (Class 2) with impressive hill-climbing ability for a folding bike.
Torque Sensor Upgrade (New!)
Unlike the original Sinch’s cadence sensor, the Sinch.2 features a torque sensor. This advanced technology measures exactly how hard you pedal and delivers proportional motor assistance. The result feels natural and intuitive.
Removable Battery with 40-Mile Range
The 48V 10Ah removable lithium-ion battery provides up to 40 miles of range on a single charge in pedal-assist mode. The Aventon – Sinch.2 Ebike battery locks securely into the downtube and can be charged on or off the bike in just 4–5 hours.
Foldable High-Step Frame
The Sinch.2 features a patented folding mechanism with a 6061 aluminum high-step frame. The Aventon – Sinch.2 Ebike folds in the middle, reducing its size for storage and transport. The handlebars and pedals also fold for maximum portability.
Folding Dimensions
When folded, the Sinch.2 measures approximately 36″ x 22″ x 28″. It fits easily into car trunks, RVs, boats, SUVs, and small apartments. The Aventon – Sinch.2 Ebike is the ultimate space-saving electric vehicle.
Fat Tire Design
The Sinch.2 rolls on 20″ x 3″ fat tires that provide excellent traction and stability. The Aventon – Sinch.2 Ebike handles pavement, gravel, grass, and light trails with confidence. The smaller 20″ wheels contribute to the compact folded size.
Front Suspension Fork
The 60mm front suspension fork absorbs bumps and vibrations, keeping you comfortable on rough roads. The Aventon – Sinch.2 Ebike smooths out potholes, cracks, and uneven pavement that would rattle other folding bikes.
Hydraulic Disc Brakes
Safety comes first. The Sinch.2 is equipped with hydraulic disc brakes (180mm front and rear). These provide superior stopping power with minimal hand effort, especially important given the bike’s weight.
Integrated Lighting System
Say goodbye to disposable batteries. The Aventon – Sinch.2 Ebike features integrated front and rear LED lights powered directly by the main ebike battery. The rear light includes a brake light function that brightens when you slow down.
Color Display with App Connectivity
The backlit color LCD display shows speed, battery level, assist mode, trip distance, and more. It includes a USB-C charging port for your smartphone. The display integrates with Aventon’s companion app for firmware updates.
Pedal-Assist and Throttle
Choose from 5 pedal-assist levels plus a thumb throttle. Pedal-assist mode uses the torque sensor for natural feeling. Throttle-only mode gets you up to 20 mph without pedaling — perfect for quick trips.
7-Speed Drivetrain
The 7-speed Shimano drivetrain provides reliable shifting across varied terrain. The Aventon – Sinch.2 Ebike ensures you always have the right gear, even if the battery runs low.
Step-Through Option Available
The Sinch.2 is also available in a step-through frame. For riders who prefer easier mounting, check out our Aventon Sinch.2 Step-Through Ebike. Both versions share the same upgraded motor and torque sensor.
Included Accessories

The Aventon – Sinch.2 Ebike represents the biggest upgrade in Aventon’s folding lineup. The move from a 500W motor to 750W transforms the riding experience. Hills that challenged the original Sinch are now effortless.
