DESCRIPTION

The Best Folding E-Bike, Now Even Better

Aventon has taken the beloved Sinch.2 and made it extraordinary with the new Sinch 2.5. 

Alongside a refreshed design and eye-catching new colours, this upgraded folding e-bike features premium upgrades like hydraulic disc brakes, a smoother drivetrain, a suspension seatpost for added comfort, and more.

With its 500W motor, the Aventon Sinch.2 achieves:

• 25 kph top speed (32 kph for off-road use)
• 60Nm of motor torque
• 88 kilometres on a single charge

Thanks to these upgrades, which are built into Aventon’s reliable design, the Sinch 2.5 is set to redefine what a folding e-bike can do.

Still more power than your standard folding e-bike

The Sinch 2.5 keeps the same dependable power and performance that set the Sinch.2 apart from regular folding e-bikes. Its 500W rear-hub motor (750W peak) delivers speeds up to 32 kph (off-road use), whether you’re riding on city roads or uneven trails. Aventon’s intuitive torque sensor continues to deliver natural rides that match your pedalling efforts.

The integrated 48V battery with LG cells charges quickly and gives you plenty of range (up to 88 kilometres), while 4” fat tyres provide stability and grip for a smooth ride on any surface.

New and improved side display

The new Aventon Sinch 2.5 sports an upgraded side display that combines a stylish look with practical functionality. Inspired by the straightforward design of classic MP3 players, using this display, you can easily navigate your ride settings with intuitive controls right at your fingertips.

Plus, the addition of a USB-C port lets you charge your phone on the go, so you can stay connected wherever your journey takes you.

Hydraulic brakes for more powerful stopping

The Sinch 2.5 upgrades from the mechanical brakes of its predecessor to premium Tektro hydraulic brakes. While the older mechanical brakes did their job well, the new hydraulic brakes provide enhanced stopping power and smoother modulation. 

Whether you’re commuting or riding on challenging terrain, the hydraulic braking system ensures quick and reliable stops for a safer, more enjoyable ride.

Suspension seat added for better comfort

With the addition of a suspension seatpost and an Aventon-branded large saddle, the Sinch 2.5 offers a smoother, more comfortable ride. The padded suspension seatpost absorbs road impacts, ensuring you experience less jarring and more enjoyment as you ride.

The same convenient, compact design

You’ll find it easy to ride the Aventon Sinch 2.5 with its simple step-through frame that allows you to place your leg through the open space in the middle. The frame and handlebars also fold into a small, compact size for easy storage. 

The locking mechanism is secure and stable, so you can forget about the anxiety-inducing rattling and clicking noises you hear on most folding e-bikes. 

The pinnacle of folding e-bikes is here

The Sinch 2.5 takes everything you loved about the Sinch.2 and makes it a lot better with upgraded components and improved performance. Whatever your ride entails—whether it’s a simple commute or an adventurous ride on tough trails—you can enjoy unmatched power, comfort, and convenience. 

Experience the next level of versatility and performance with the Sinch 2.5.

TECHNICAL OVERVIEW

Sinch 2.5 ships as a Class II ebike, with pedal assist and throttle. Sinch 2.5 will also operate with the throttle unplugged and removed, should you want to ride in an area where throttles are prohibited. Aventon ebikes are built to the IPX5-rated standard. An IPX5 rating means the bike is protected against low-pressure water jets from any direction. This provides a moderate level of water resistance, allowing you to ride in light to moderate rain or through small puddles. However, IPX5 does not mean waterproof—Aventon ebikes are not designed for full submersion. Avoid using a pressure washer or high-pressure sprayer to clean your ebike, as pressurized water can still damage components. *Max range determined using PAS Eco throughout flat terrain with a rider weight of 73 kg.
