The Ultimate Folding E-Bike, Elevated

Aventon has reimagined its popular Sinch.2 and introduced the new Sinch 2.5—a folding e-bike that’s more refined, powerful, and comfortable than ever.

With a sleek redesign and bold new color options, the Sinch 2.5 brings premium upgrades, including hydraulic disc brakes, an improved drivetrain, a suspension seatpost, and more.

Powered by a 500W motor, it delivers:

• Top speed: 32 kph

• Torque: 60Nm

• Range: Up to 88 km per charge

These enhancements, paired with Aventon’s trusted engineering, set a new standard for folding e-bikes.

 

Just like its predecessor, the Sinch 2.5 outperforms typical folding e-bikes with its 500W rear-hub motor (750W peak), propelling you to speeds of 32 kph with ease. A responsive torque sensor ensures a natural pedaling experience, while the 48V LG battery charges quickly and delivers long-lasting range. Wide 4” fat tyres add grip and stability across city streets and off-road trails.

 

The upgraded side display combines style and practicality, echoing the simplicity of classic MP3 players. With intuitive controls, managing your ride settings is effortless. A built-in USB-C port also keeps your phone charged while you ride.

 

Replacing the mechanical brakes of the Sinch.2, the new ektro hydraulic system ensures stronger stopping power and smoother control, giving you safer, more reliable braking performance whether commuting or tackling rough terrain.

 

A suspension seatpost and a wide Aventon-branded saddle absorb shocks and bumps, making every ride smoother and more enjoyable.

 

The Sinch 2.5 retains its signature step-through folding frame, making it easy to mount and store. The sturdy folding mechanism keeps everything secure—no more rattles or clunky noises.

 

By building on the strengths of the Sinch.2 and adding thoughtful upgrades, the Aventon Sinch 2.5 delivers exceptional power, comfort, and versatility. Whether you’re cruising through the city or adventuring on rugged paths, it’s the folding e-bike that truly does it all.

Technical Overview

The Aventon Sinch 2.5 ships as a Class II e-bike, equipped with both pedal assist and throttle. If you’re riding in regions where throttles aren’t allowed, the bike can also operate with the throttle unplugged and removed.

Every Aventon e-bike, including the Sinch 2.5, is built to the IPX6 water resistance standard. This means the bike can handle high-pressure water spray from any direction—making it safe to ride in heavy rain or through splashes of mud and puddles.

Note: IPX6 means water resistant, not waterproof. Avoid submerging your e-bike or cleaning it with a pressure washer, as direct pressurized water can still damage electrical components.

*Maximum range tested using PAS Eco mode on flat terrain, with a rider weight of 73 kg.
