Should you buy one?
Yes, if you can find a good one used. The original Aventon Sinch is a blast to ride, and I’d recommend it to anyone shopping for a fat tire folding e-bike. It has more power than a lot of the e-bikes I tested around the same time, it beat its own rated range on my test, and it folds up relatively small while still giving a full-size adult a comfortable ride.
I filmed this review in April 2020. Aventon no longer sells the original Sinch. Its old product page is gone, and as of Oct 22, 2026, the current version on aventon.com is the Sinch 2.5 at $1,799, listed as sold out. Everything in this review is about the original bike I tested.

Sources: Aventon’s original Sinch page no longer exists, so every row except the last comes from my April 2020 video (4:27, 4:44, 5:25, 5:30). I didn’t give battery amp hours, weight, payload, tire size or price in the video, so they’re left out. The Sinch 2.5 price is from aventon.com.
Two notes:
- Battery cells. Aventon used Samsung cells in the 48V battery, and that’s part of why the range is so good.
- Speed. I hit above 30 mph only with some pretty decent pedaling in top gear at full assist. That’s my result, not a rating. If you care about where you can ride at that speed, read my guide to Class 2 vs Class 3 e-bikes.
What the specs mean on the road
500W sustained, 750W peak. The sustained rating is what the motor can hold for a long climb or a long ride. The peak is the short burst you get pulling away from a stop. At my 200 lbs, that burst is why I said it takes off.
48V battery with Samsung cells. I credited the cells for some of the range.
40 mile rating, 42 on my test. I beat the rating. Range always depends on rider weight, terrain, temperature, tire pressure and how much you use the throttle, so treat my 42 as one result, not a promise.
Fat tires on a folding frame. Fat tires add cushion and grip, which is what makes a small folding bike feel comfortable for a full-size adult. They also add weight and noise, and the noise is something I noticed.
Above 30 mph. Where you can legally ride at that speed depends on your state. See my e-bike laws by state pages.
Pros and cons
Pros
- Comes completely put together. No front wheel to install.
- Charger and a multi-tool are in the box
- Sturdy construction with premium finishes you can feel
- 750W peak motor with a ton of power, even at my 200 lbs
- 42 miles on a full charge in my testing, beating the 40 mile rating
- Removable, key-locked battery in a solid case you can carry inside
- Waterproof flap over the charge port
- Display shows everything I need
- Folds small enough for a Tesla Model 3 trunk (barely)
Cons
- My leg hit the folding clip on the center frame a few times while riding
- The fat tires are way noisier than regular e-bike tires
- Getting it into a Model 3 trunk is tight, so I wouldn’t do it every day
- You have to fold the bike to get the battery out
- Discontinued, and the current Sinch 2.5 is sold out on aventon.com
Unboxing
This is one of the few e-bikes you get out of the box completely put together. There’s no front tire to put on. It comes with everything you need, including the charger and a really cool multi-tool so you can adjust the bike as you see fit.
Once you get the packing material off (and take a short bubble wrap break), you unfold it and hop right on. That’s the whole point of a folding bike.
Build quality
Construction wise, this is a really sturdy bike. I was very impressed with the build quality compared to some of the other e-bikes I’d been testing. The last bike I tested before this one, the Eahora XC100, was definitely a baseline bike. The Sinch is not. There are so many premium finishes on this bike, and you can tell just by touching them and looking at them.
Charging and the battery
Charging is very simple. If you can plug in a cell phone, you can plug in an e-bike. There’s a little waterproof flap over the port that came in handy during my testing. The charger light switches to red while it’s charging, then back to green when the battery is full.
To get the removable battery out, you have to fold the bike. Folding is pretty effortless, handlebars included. Then you use the key that’s provided and slide the battery out.
The battery comes out in a nice solid case you could throw in a bag. Say you ride this to work and keep your charger there. You can leave the bike outside, bring just the battery in, and charge it at your desk.
Folding and the car test
I tested the Sinch in the trunk of a Tesla Model 3, which is a regular sedan trunk, and I was able to get it fully inside. It was pretty tight, though. If my commute meant driving to a big parking garage and folding it in and out multiple times a day, I think that would be too much.
The ride
This bike is a blast to ride. The motor is a brushless 48V hub rated 750W peak and 500W sustained, and it has a ton of power. I’m about 200 lbs and this thing takes off.
Getting it to max speed is no problem. With some pretty decent pedaling in the top gear at the full assist level, I could easily get it above 30 mph.
The huge tires give a really comfortable ride, but they are way noisier than a regular e-bike tire. The display on the handlebars is exactly what I’d expect on a more premium e-bike, and it shows me all the information I need.
Range
Aventon rated the original Sinch for 40 miles. On a full charge, I took it 42 miles. That’s better than the rated range, and I give the Samsung cells some of the credit.
The one real complaint
The clip on the center frame that folds the bike in half got in my way. While I was riding, my leg hit that clip a few times. It’s the only real complaint I had.

- Ziprs F1: a smaller, non-fat-tire folder for paved commutes. It doesn’t have suspension.

Who it’s for
- Riders who want a fun, powerful folding e-bike. At 200 lbs, I had plenty of power.
- Commuters who charge at the office. The battery comes out and goes inside with you.
- People with occasional car trips. It fits in a sedan trunk, just barely.
Who should look elsewhere
- Daily car-to-bike commuters. Folding it into a Model 3 several times a day would be too much.
- Riders who want a quiet bike. Fat tires are loud.
- Anyone who wants a new one. The original Sinch is discontinued.
