Unique Features of the Aventon Sinch Step-Through Foldable Electric Bike

The Sinch is a highly-refined, extremely versatile folding electric bike. It can go with you, and take you, anywhere.

Aventon

On trail or on pavement, the Aventon Sinch excels.

A Versatile Folding Electric Bike

Perhaps the most unique feature of the Aventon Sinch is its foldability. The aluminum alloy frame features a step-through design that makes it so you don’t have to swing your leg over anything to get on or off the seat. As such, the frame appears to be one solid beam, but in fact, it folds in a hinge at its lowest point near where the pedals connect.

The frame, hinge, and locking latch are incredibly robust, and the electric connections have been reinforced. Additionally, there’s a rigid stand that props up the entire ebike when you do fold it in half. It’s all very well thought out.

A compact package.

Along with the frame, the pedals fold in, and the handlebars fold down. This creates a compact package that can easily be stowed in a small vehicle’s trunk or an RV’s exterior storage space. And the best part? It takes less than a minute to fold down or unpack.

Conveniently Powerful Electric Pedal Assist and Throttle

Though the Aventon Sinch does have seven easy-to-shift mechanical gears utilizing trigger shifters and a high-quality Shimano Acera derailleur, you can ride full-electric throttle if you so choose. The 672Wh battery can keep you cruising for 30 miles without a single rotation of the pedals after launch, and it’ll keep you moving for over 50 miles when using pedal assist.

Smooth gearing.

Speaking of which, there are five levels of pedal assist. You can utilize the various levels to achieve higher top speeds of up to 20 MPH (top speed is limited by default, but you can make it higher in the settings menu of the backlit color display). Alternatively, you can use the different levels of pedal assist to dial in just the right amount of torque to help you power up hills or navigate uneven terrain while biking off-trail.

The electric power passes through a 500w brushless hub motor. The battery can be charged while in the ebike’s frame for convenience, or it can be unlocked with a key and taken indoors separately as well. The Aventon Sinch is rated IPX4 water-resistant, which means all electrical components are safe from rain and minor splashes, but it’d be best to avoid submerging your ebike.

Where the magic happens.

A Remarkable Attention to Detail

We’ve already touched on the Aventon Sinch’s practicality and versatility, and a big part of that is because this is a fat tire electric bike. The 20-inch by 4-inch gum sidewall fat tires have a supple feel that absorbs potholes, roots, and rocks, and the fairly aggressive tread offers plenty of grips even when the streets or trails are slick with rain and mud.

Plus, the RST Guide suspension fork adds to the ride comfort, and the mechanical disc brakes provide supreme stopping power even in wet-weather conditions.

Off Trail Aventon

Electric pedal assist and soft suspension make off-trail exploring a joy.

And the backlit display mounted on the handlebars provides all of the relevant information you need to know about your bike and your trip. It contains a speedometer, odometer, battery level, power output, and more. The settings can be adjusted on the fly, and you can connect your Aventon Sinch to the Aventon mobile smartphone app for even more features and insights.

    The only negative is he weight. It great that it folds up, but doesn’t it still weigh 300 lbs? There are not a lot of people that thin they would need the peddle assistance and can lift 300 lbs. My wife is a wheelchair that has gotten larger over the years. At one time though she had a scooter that broke up into multiple parts that made it possible for me to put in the back of the van. Even removing the batteries would still leave a 230 pound part.

    1. It does weigh 68 pounds. While lifting may not be possible for everyone, the folding aspect is still great for sliding under a desk, into a closet, or into the corner of a storage shed. The bike can be moved around on the ground when folded—you can slide it on the tire rubber to move it exactly where you need it. I’m currently keeping the Sinch in an outdoor storage closet where I have two other bikes, and the Sinch takes up much less floor space than the other two.
