Frame and Contact Points
This is the Aventon Sinch folding e-bike, and it lives up its name because it is indeed a cinch to both fold and ride. But more than that, this folder is built tough. It’s got a chonky frame with a beefy folding mechanism, front suspension and fat tires. The Sinch is a great road warrior, but it’s also trail ready for those seeking adventure.
The Aventon Sinch has a starting price of $1,799 USD and comes in one color, matte grey, and one frame size. It’s also available in a step-through version, which we recently reviewed as well. We’ll drop a link to that one in the description.
Aventon offers a 14-day return policy, which is awesome, and a 1 year comprehensive warranty, which is also awesome.
And with that, let’s dive into the specs.
The Aventon Sinch has a modestly powerful 500 watt hub motor that can bring this ride up to a top speed of 20 mph out of the box. And that speed can be reached using the cadence sensing pedal assist, or the thumb throttle.
500 watts is what we call the goldilocks zone of e-bike motors. It’s going to get you up to speed quickly enough, and it’ll still take the ill out of hills, but it’s nowhere near as power hungry as a 750 or 1,000 watt motor, which really helps with increasing range.
So, let’s talk about the battery, because it’s pretty sweet. The 48 volt, 14 amp hour, locking and removable battery is stuffed inside the main tube. And it is COMPLETELY concealed. This battery configuration rocks out harder than Van Halen for a few reasons.
First, it means the battery, and it’s sensitive electronic components, are going to be protected from the elements. This keeps the battery clean and drastically reduces the risk of damage.
Second, the battery’s location is smack in the middle of the Sinch. This makes for a well-balanced e-bike that is easy to maneuver.
And third, because the battery is hidden, this e-bike is pretty stealthy. The only real giveaway is the hub motor. That, and the fact that you’ll probably be flying past everyone riding an analogue bike.
This battery offers a max estimated range of 40 miles per charge, and while there are tons of variables that impact the range, this is actually a fair estimate. During testing we rode for about 20 miles on the max pedal assist setting, and we used the throttle generously. We also road through a lot of grass and had TONS of starting and stopping, which really eats into the range. Still, at the end of filming we were at about 50 percent battery level. Pretty impressive actually.
One of our favorite things about the Sinch is the frame. It’s well-built, with a curb weight of approximately 68 pounds, and a max payload capacity of 300 pounds — higher than average for a folder.
The weld points are clean too, and the frame folding mechanism looks extremely durable. And with a two-stage frame latch, this frame is locked firmly in place. This is ideal for those who want to take the Sinch on some trail riding, and the RST Guide front suspension and 20 inch by 4 inch fat tires make this folding electric bike even more rugged.
Still, we don’t recommend heavy trail riding with the Sinch. The folding mechanism on the handlebars isn’t as durable as the one on the frame, and with extreme riding it’s possible the handlebars could collapse. Not ideal.
On the upside, the handlebar stem is telescoping, so it can be adjusted to perfectly fit just about any rider. There’s also a quick release latch at the top of the handlebar stem, and this allows riders to adjust the angle of the handlebars and the brake levers. This is a small piece, but it’s actually pretty handy.
At the back of the Aventon Sinch we’ve got an impressive Shimano Acera 7-speed derailleur paired with trigger shifters. And if you’ve been with us here at Electrified Reviews for any length of time, you’ll know how much we absolutely LOVE trigger shifters. We’re giving Aventon 10 points for this.
At the front chainring we’ve got a double-sided aluminum bash guard. This is great for preventing damage to the chainring in the event of a strike, and it also helps to minimize derailments by keeping that chain locked tightly in place.
To bring the Sinch to a stop, we’ve got Tektro mechanical disc brakes with 180 mm rotors in the front and rear wheels. These brakes offer plenty of stopping power, especially with the 20 mph out-of-the-box top speed in mind, and they are also equipped with motor inhibitors to ensure you’ve always got the shortest possible stopping distance.
Let’s take a look at the electronics. On the left side of the handlebars we’ve got the independent button pad with rubberized buttons. They feel nice to push. We’ve also got the thumb throttle.
In the middle of the handlebars rests the LCD color display. This display is backlit and organized nicely, but it can be a little hard to read in direct sunlight.
Aventon also has an app that you can sync with your bike for anyone wanting a deep dive on their ride analytics. There’s a lot of good info there, and a social sharing platform as well.
Overall, the Sinch is another fantastic offering from Aventon. It’s definitely a value-buy at $1,799 USD and has a good component layout. And the fact that it’s foldable just means you can throw it in the back of your car and go find your next adventure.
