The second iteration of Aventon's Sinch has changed so much that I hesitate to even consider it the same model. It's step-through now, it's got a rack and fenders, more advanced lighting, a telescoping stem, a torque sensor... but what the heck, it's the Sinch.2! It is still a fat-tired folding bike on 20x4" fat tires, and even more of a blast to ride thanks to that torque sensor. The basic suspension fork allows for comfortable riding in the city and on light trails, but it doesn't have a ton of travel so don't get too crazy. Another benefit of the new frame is that it's a lot easier to remove the battery; on the previous Sinch you had to fold the bike first before exposing the battery, which was inconvenient.
Really the only downside for the Sinch.2 is the brakes; they're good quality disc brakes, but they're mechanical as opposed to hydraulic. That means they take more grip force to activate, and they'll need occasional maintenance to tighten up the cables. For a bike that weights roughly 70 pounds and can carry up to 300 pounds of rider and cargo, hydraulic brakes would be a real plus.

What Other Experts Are Saying
Before purchasing a personal electric vehicle costing hundreds or even thousands of dollars, it's important to do your research to make sure you get the right one! Even though we'd love to personally review every single EV out there, there's just too many out there for us to possibly cover them all. That's why we've worked hard to curate reviews from other experts in the industry. We only show an excerpt of each review here; please use the "Read Full Review" button to get the full story on their website and support their excellent work!
"The Aventon Sinch.2 is a compact and powerful electric bike that is designed to be compact, rugged, and able to fit a variety of use cases. With its torque sensor technology, fat tires, and folding frame, this Ebike is perfect for urban adventurers, off-road enthusiasts, and casual riders alike. ..."
"I love that the company has included a torque sensor in the bike, which makes for a very nice upgrade to the pedal assist operation. There are now four levels of pedal assist instead of five, but with the torque sensor is still a major upgrade because the pedal assist doesn’t just stick you in a preset speed based on pedal assist level. Instead, it actually modulates power in proportion to how hard you’re pedali..."
"Turn signals are another excellent inclusion on the updated model! We always advocate for safety and responsibility on the road (or trail), and this feature makes it much easier to communicate your intentions to other drivers, riders, and pedestrians. Aventon’s decision to install seat-stay-mounted brake lights and turn signals on their latest e-bikes raises the bar for other brands whose products dwell in the $150..."
"It would have been great to see the rear Tektro mechanical disc brakes replaced by a hydraulic set and to retain the Shimano shifter and derailleur, although the Aventon branded components were fine in our testing. Gears are a 12-32 teeth cassette at the rear and a 48-tooth double-sided front chainring. The 20″x4″ Chao Yang tires have an attractive brown sidewall and more of a street tread, less useful for rough..."
"In short: The Aventon Sinch folding e-bike is a really solid option for a city commuter. The bike has some get-up-and-go when the pedal assist is on. It’s got beefy 4-inch fat tires and a claimed range of 55 miles to a single charge, and, of course, it folds in half. It’s easy to store in a closet or garage, and it transports fairly easily on a bus or in a car. It is heavy, though. Lugging this thing upstairs, or..."
"I don’t like when e-bikes have complicated controls. The remote to operate the bike that is on the left side of the handle is super easy to navigate. A few buttons let you change the pedal-assist level while biking. You can choose between Eco, Tour, Sport, and Turbo (or leave the pedal assist off completely). Because the controls are simple and right at your fingertip, it’s easy to switch to the mode that you wan..."
"The Aventon is supremely smooth and comfortable to ride, with plenty of stability for a folding model. The RST Guide ML-20 suspension fork does a good job of dampening the ride over bumps and cracks in the road, even with just 45 millimeters of travel. You can lock out the fork if you don't want the suspension's dampening effect. Thick 4-inch tires provide plenty of air volume, improving the cushy ride. This bike rem..."
