ADDITIONAL INFORMATION

Sinch ships as a Class II ebike, with up to 20 MPH on 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 poweful motor can go up to about 24 MPH on pedal assist. 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.

Too much fun

My first ever ebike. Love the style. Love the functionality. I've only had the bike a few weeks, but it has met every expectation so far, and it has just been a blast to ride. The bike was delivered as expected, and as I was opening the box I realized I hadn't been so excited about a bicycle since I was a kid, and that was a long time ago.

The bike is very rugged, seems well built, and as many have said, is bigger than you think. That's what I was hoping because I'm a fairly big guy myself. The bike is a little heavy, but because it's foldable I often leave it in my Jeep and just bring the battery in to recharge. That adds to the convenience of riding whenever and wherever.

This was not an inexpensive purchase, but I'm glad I bought this bike. Because of the fun factor, the list of competitors is growing fast. My research confirmed Aventon had the reputation I could trust to stand behind the product. I'm a satisfied customer, and the people who see my bike want one too.

Sinch Review

I’m very happy with the bike. Good job Aventon! It shipped out the same day I ordered it. Fed ex delivery was quick. It was already assembled except for a couple minor parts. I bought it mainly for my boat. So when we travel to a different port we have transportation now. It folds up small enough to stow away. The detail is amazing and everything works perfectly. If you are buying a fat tire bike I would definitely suggest a fat tire e bike like the Sinch. Fat tires weigh more and are harder to peddle. The Sinch makes it a pleasure with the adjustable power assist. I’m using it off road more then expected. The power is great and it does 20 without even peddling. It’s smooth!

Its a Sinch

The bike is a looker and has an unique look. As everyone says first.... It is bigger than it looks. In the folding market, this might be the boss, but the flip side is that folding only saves a bit of space. It is too heavy to carry far and too large to fit in smaller cars without effort. There isn't a way to secure it folded and there doesn't seem to be a way of lifting and carrying it that isn't awkward. 4 inch tires are almost too big to have this feature make a lot of sense.
The hidden battery is super nice and you can charge without having to take it out. Its a quality bike and does what it promises to do. I just recently added fenders which after one ride, you wonder how they sell the bike without them. If the fenders and a cargo rack were included then the starting price sounds right. After researching for days, it does seem to be priced a bit high, even more so sitting next to the loaded Level. Its a great bike that you will enjoy.
