Sinch ships as a Class II ebike, with pedal assist and throttle. If you are riding on private property or in an area without ebike speed restrictions, the speed limit can be modified in the settings, and Sinch's powerful motor can go up to about 4 MPH above the factory set top speed. Sinch can also operate with the throttle unplugged and removed, should you want to ride in an area where throttles are not allowed.

Aventon ebikes are built to the IPX4 water-resistant standard. IPX4 means that your bike is resistant to water splashes from any direction. This means it’s OK to ride or park your ebike in the rain. It won’t be harmed by spray from a wet road or raindrops. Your ebike is not intended to be submerged or subjected to a pressurized spray. Don’t use a pressure washer or sprayer to clean your ebike.

Aventon Sinch Folding Ebike Reviews

There are several top-notch ebike reviewers in the US, who consistently deliver comprehensive and independent reviews of electric bikes. Because the Aventon Sinch is such an iconic folding electric bike, we have a wealth of 3rd-party reviews to help us decide if the Sinch is right for you.

Electric Bike Review (EBR)

First up is the review by Electric Bike Review, which they provide in a detailed write up and the video review below. Court Rye and his team were very impressed with the Sinch, summarizing their review as follows:

The Aventon Sinch is a value-priced fat tire folder with a beautiful visual appearance thanks to internally routed cabling and paint-matched components, Kenda Krusade tires can tackle any terrain and include puncture resistance. 

A 500 watt motor from Shengyi provides satisfying power and is activated via either a thumb throttle or the sealed cadence sensor, spring suspension fork from RST provides a smooth ride experience, and the telescoping stem extends high enough to fit tall riders.

The Shimano Acera derailleur is a great step up in quality and provides a satisfying shifting experience with rapid-fire trigger shifters, mechanical disc brakes from Tektro give solid stopping power and include motor inhibitors, optional fenders are sturdy and provide full-length coverage.

The throttle cannot be activated while stationary which can be a challenge when combined with the limited range of the 14-28 tooth freewheel, no accessories are included but many good ones are available as optional add-ons.

EBR collected a service fee to make this review possible. This is not an endorsement, we strive to be objective.

Brent McCluskey - Electrified Reviews

Brent McCluskey is another highly qualified independent ebike reviewer. You can read the Electrified Reviews review of the Aventon Sinch, and watch their video below. They say that the Sinch "is a well thought out fat tire folder with some seriously upgraded components, plenty of power and an eye for design."


Finally, we have the review of the Sinch by Micah Toll at Electrek. Micah is a world-renowned electric bike builder and reviewer, and he operates at the highest level of integrity. You can read the Electrek Review of the Sinch and watch their corresponding video review. They state that "this ebike offers the unbridled joy of cruising around on ridiculously oversized tires yet without sacrificing any build quality. That makes it a top value ebike for anyone looking for lots of bang for your buck."
