Portable Power in a Classic Package
The Aventon – Sinch Foldable Ebike combines the portability of a folding bike with the power and stability of fat tires. Unlike the step-through version, this high-step model offers traditional bike styling for riders who prefer a classic top tube.
Foldable High-Step Frame
The Sinch features a patented folding mechanism with a 6061 aluminum high-step frame. The Aventon – Sinch Foldable Ebike folds in the middle, reducing its size for storage and transport. The high-step design offers superior frame stiffness and traditional bike aesthetics.
Powerful 500W Motor
At the heart of the Sinch is a 500W brushless rear-hub motor that peaks at 750W. The Aventon – Sinch Foldable Ebike accelerates smoothly up to 20 mph (Class 2) with impressive torque for a folding bike. Hills, gravel, and city streets are all within reach.
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 battery locks securely into the downtube and can be charged on or off the bike in just 4–5 hours.
Fat Tire Design for All Terrain
The Sinch rolls on 20″ x 3″ fat tires that provide excellent traction and stability. The Aventon – Sinch Foldable 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 Foldable Ebike smooths out potholes, cracks, and uneven pavement that would rattle other folding bikes.
Hydraulic Disc Brakes
Safety comes first. The Sinch 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 63-pound weight.
Integrated Lighting System
Say goodbye to disposable batteries. The Aventon – Sinch Foldable Ebike features integrated front and rear LED lights powered directly by the main ebike battery. The bright headlight illuminates your path at night, while the rear light keeps you visible.
Cadence Sensor
The Sinch features a reliable cadence sensor. This system measures pedaling motion and delivers consistent motor assistance. The Aventon – Sinch Foldable Ebike provides predictable, steady power delivery that works well for casual and commuter riders.
LCD Display
The backlit LCD display shows speed, battery level, assist mode, trip distance, and more. It includes a USB charging port for your smartphone. The display is easy to read in direct sunlight.
Pedal-Assist and Throttle
Choose from 5 pedal-assist levels plus a thumb throttle. Pedal-assist mode delivers consistent power based on your selected level. Throttle-only mode gets you up to 20 mph without pedaling — perfect for quick trips or resting.
7-Speed Drivetrain
The 7-speed Shimano drivetrain provides reliable shifting across varied terrain. The Aventon – Sinch Foldable Ebike ensures you always have the right gear, even if the battery runs low.
Folding Mechanism Details
The Sinch folds in seconds. Release the locking collar, fold the frame at the center hinge, and secure the latch. The handlebars and pedals also fold. The Aventon – Sinch Foldable Ebike fits easily into car trunks, RVs, boats, and small apartments.
High-Step vs. Step-Through
The high-step frame offers traditional bike styling and superior stiffness. For riders who prefer easier mounting, check out our Aventon Sinch Step-Through Foldable Ebike. Both versions share the same motor, battery, and folding mechanism.

Why Choose the Aventon Sinch High-Step?
The Aventon – Sinch Foldable Ebike solves the biggest problem for urban and mobile riders: storage. Fold it and store it under a desk, in a closet, or in the trunk of a compact car. Take it on vacation. Live the RV lifestyle. Never worry about bike racks again.
The high-step frame offers traditional bike styling that many riders prefer. The top tube provides superior frame stiffness, which translates to better power transfer when pedaling. If you’re comfortable swinging a leg over a traditional bike, the high-step Sinch is for you.
Despite its folding frame, the Sinch doesn’t compromise on power or capability. The 500W motor, fat tires, and front suspension tackle terrain that would defeat other folding bikes. Hydraulic disc brakes provide confident stopping power.
At 63 pounds, the Sinch is heavy for a folding bike — but that weight translates into durability, stability, and a 300-pound rider capacity. The Aventon – Sinch Foldable Ebike is more than a folding bike; it’s freedom to ride anywhere, store anywhere, and explore everywhere.
