  1. Mensah Drake

    I just finished unboxing the Sinch Step-Through and wow!! It is a beautifully constructed bike and the process of unboxing and initial setup was a breeze. I purchased one for myself and a matching one for my wife. It’s really straight forward and completely intuitive how everything goes together. Haven’t ridden it yet because it’s been raining cats and dogs here. I just need to put the fenders on then we give it our first test ride. I’ll review that process later this week. We’re packing them in our 5th wheel today and heading for a week at a campsite in Pigeon Forge, TN. I will take some photos and include with the next review.

  2. Sahla J

    We absolutely love our bikes. We use them to go all over town. The foldable part was the selling point for us as we have a bronco sport and can fold both bikes and carry them both inside without a bike rack.

  3. Castro Mandana

    These bikes are built like tanks. It doesn’t come across that way on the pictures or videos I watched. They are good sized & stout. I bought it as a shuttle vehicle when floating the river but it’s too much fun for just that. Looking at getting a second for the wife now that she rode it.

  4. Gabi Deli

    My husband and I purchased Sinch ST bikes and absolutely LOVE them! We ride every day.

  5. Derick Finie

    A bike that weighs nearly 70 pounds might as well not fold; its weight makes it difficult for most people to lift into confined spaces.

  6. Rageon G

    I’ve put 250 miles on the Sinch since I’ve bought it 3 weeks ago. It is so fun to ride but it does getting some use to. Pedal assist is a little intermittent when slowing down then speeding back up( about 3 full pedal rotations) I use it for commuting and does a great job. It is a conversation starter no doubt. I’ve had many compliment the bike. 👍🏼😎👍🏼

  7. L.

    The Aventon Sinch step through is portable and stylish. I can fit my bike in the hatchback of my vehicle and bring it anywhere I go. This ebike is also very high quality. It can hold a charge all day long depending on how often you use the pedal assist and it can even handle the off road trails.

  8. Drew Wati

    Definitely the best e bike. Very much worth the price.

  9. Yerala Sabum

    This bike is exactly what I’ve been needing to enjoy riding again, with the pedal assist it helps with my knees not to hurt during rides and equals to longer rides. On top of that with the step through design it makes it so easy to get on and off. I’ve been averaging 20 miles per ride since I got this bike, I’ve already logged 300 miles in the first month of ownership. This bike will help me stay active and live a healthier lifestyle.

  10. Basilo Chetri

    I just bought the red Sinch step thru! I love it! I did alot of research on different bikes and this one had all the options I wanted and is a good price point for a good quality bike!

    Fun! Fun! Fun!

  11. Howler Starter

    I recently purchased the Sinch ebike. I am very happy with it. It has plenty of power and handles very well. I also like the looks of the bike. It is very sturdy. You can easly control the amount of exercise and speed you want. I would buy again.

  12. Ruben Haji

    Once my new Sinch E-Bike made it home to me from it’s trip around the country and delay’s in shipping it proved to be easy to setup and take for a ride. There was minor damage from shipping but nothing to send it back about. Our local shop looked it over and straightened out the brakes. No problems have arisen sense. Thanks

  13. Lumber Ferald

    Had it delivered to my winter home. Won’t be there for another month. Can’t wait to assemble and ride it! Delivered quickly. Appreciate that!

  14. Inanda Ari

    Very happy with the bike so far. I was a little worried the 500w motor wouldn’t keep up with my friend’s 750w, but it isn’t a problem at all and find myself outpacing them. Bike folds up nicely and isn’t too bad to lift when you remove the battery and seat. I bought a doggie hammock for the backseat of my car and just put the bike in there and belt it up.

  15. Austin

    Amazing bike. Very comfortable and high quality materials. Love it

  16. Xander Cirus

    This is my first ebike. I’m really pleased I purchased it. I like that the throttle and pedal assist changer are easy to reach when needed. I did not notice a difference using pedal assist five, but for my purposes mostly I wouldn’t need it. I’m mostly riding on flat bike trails and I can get up to a nice speed. Buy the sinch step through ebike. It will not disappoint.

  17. Onana N

    Great bike with awesome range! I wouldn’t recommend for anyone over 5’10” but fits me great!

  18. Meyers D

    I have had the bike for 3 weeks now and absolutely love it! I feel like a kid again, being able to explore and exercise without over exerting myself. I get a good work out and my knees are getting stronger. I should have done this a long time ago. I plan on buying another Aventon e bike for my spouse so we can go riding together. I’m excited to see how many adventures we can go on!

  19. Fernando Bani

    In the category of compact electrics bikes, this is the top of the line. Powerful and attractive.

  20. Kender Zuch

    Awesome folder, I’ve had many folders “non”electric, and this bike doesn’t make any unwanted sounds, to make you think something is coming g apart…thank you for great bikes…

  21. Joe springs

    best ebike period…

  22. Epirus Iadin

    I bought 1 for myself but made the mistake of letting my wife try it out, guess who now owns 2 Sinch ebikes and a buggy for the family dog?
    So much Fun!!

  23. Chill Resta

    I received my bike June 21st…. Today July 17 2022…. the bike doesn’t work at all.. I still zero mile on it… you call Customer service they never pick up… … I brought the sinch it Beautiful bike… I wish I get help with customer service to help fix the problem… I a. getting E30 code

  24. Gunter Carine

    My wife and I purchased two Sinch step through ebike’s in July and shipped them to our island vacation home in Belize. There are no cars on the island only golf carts and bicycles. The roads are all made of sand and the Sinch is the perfect choice for getting around, loads of fun to ride too. Being the only ebike’s on the island garnered a lot of attention and compliments.

  25. Rice Cooper

    Just got my Sinch regular last week and WOW! So much fun! The bike is extremely high quality. Solid as a tank. Super easy to use. I took my first ride and was grinning from ear to ear. The big tires make it feel super stable smooth and solid. Tackles off-road terrain just as well as paved roads. Very fast!

  26. Harry Jeans

    For the first time in years I can fully enjoy and appreciate all of the trails winding around my home in Colorado Springs. The bike is very easy to master and with its wide tires, it is very stable on ALL surfaces. Having Fun!!

  27. Hanuman Kerdira

    Love our new Sinch e-bikes! Only ridden the neighborhood so far, but planning a trip to Jekyll and looking forward to riding them all over the island. SO FAR service and communication with Aventon has been spot-on. We had to send my bike back due to a defect. My replacement bike arrived within the week. Eager to start our new bike adventures (Now just have to figure out how to haul the camper, kayaks AND our bikes

  28. Virginia H

    Very sturdy. Also very reliable

  30. Erin Cubes

    It was Aug 23rd when delivered and we opened the box like the picture.. It’s going to 2 months and so far so good.
    It folds in the garage for convenient storage.. Cloud gray looks gorgeous than white from older version and it performs strong and trustful.. Only wish I have now is the battery could last long enough to enjoy riding for a long while.. First e bike buyer, so a bit concern about almost 2k price and how shipment will be made from its size and weight, but now I think it’s worth going for it to enjoy e biking and was delivered to my front door with no issues.

  31. Alegan Serbin

    I am a 2-3 time a week avid mountain bike rider, but got the Sinch for my wife to go on street rides and to use when we go camping. I find myself taking it out often at the camp site because I really enjoy zipping around on it. I tried a long steep incline this past week and the Sinch handled it effortlessly. Definitely gets us all out riding more often and with much enjoyment. It handles well although with a few minor quirks. Glad we got the Sinch and got a lot for our money.

  32. Sten Dalas

    Life changer! Made my city seem so much smaller. Have been riding everyday. Just wishing I would have gotten it earlier in the summer (or years ago!)

  33. Ben Danish

    Good solid bikes fun to ride. Also the best way to explore that I’ve ever found. These bikes will get used alot. Might even stud some tires for winter.

  34. Green Hills

    Soo pleased I bought this bike, handles really precisely and the tires make for such a comfortable ride … Thank you Flashe!!!

  35. Diland Hertz

    The Aventon Sinch is a great looking bike. I have ridden my bike about 60 miles so far and I’ll say its been great.

  36. Baneaolo

    The Aventon Sinch is a great bike! From the ease of folding it together out of the box, to the sturdy ride the wide tires provide, this has been a great choice! I would highly recommend to anyone in the Ebike market, you will be glad you chose these.

  37. Conn Y

    The fit and finish on both Sinch ST’s I purchased was exceptional. Aventon is known for their attention to the welds on their bikes and its well deserved. This folding bike is solid when you’re riding, you’d never know it had the ability to fold. I did have a minor warranty issue with one of the bikes and Aventon handled quickly without any issues.

  38. Wet Slopan

    I am a long time cyclist; racing touring and all disciplines from road to gravel and everything in between. So when I say this is a fantastic bike, I am not exaggerating. I needed something I could easily take on the train, but also ride up to my field on my farm. The 4 inch tires and low gearing allows me to ride in the woods as well. The folks at Aventon were great. I had the bike in 3 days from ordering. 10 minutes to take it out of the box and go for a ride!

  39. Lambastome

    First off, I am 74 years old. The reason I am telling you this is because younger persons will not need to consider some of the things I’m going to type. It is heavy lifting onto a bike rack but if I can do it, you should be able to do it. I think the next time I lift it on or off the rack I will remove the battery as to shed some weight. The adventure itself was a blast. Love the big tires, neighbor calls them Gangster. Smooths out the ride quite a bit. I stiffened the front suspension quite a bit for better control at higher speeds. Electric power is great for a person of my age and there is enough to climb high grades. I used all sorts of configurations of power assist and gearing. Assist 3 and midrange on my shifter was average. I rode sidewalks like when I was a kid and rode through the grass on a soccer field, climbed a large berm, and enjoyed a gravel road. all in 6.9 miles. Loved every minute of it. As I get into better shape, I will extend my rides and become even more adventurous. Fit and finish is what I expected.

  40. Jacob Strongman

    Sinch Step-Through Foldable Ebike simply the best

  41. Carine Jen

    After purchasing one, the family had to have another. The quality of the bike has exceeded expectations. Brakes are solid and the ride is so much fun…not to mention the bike looks so good. We love it.

  42. Ellie Hasten

    When I first found out about electric bikes I began to do my research on the multiple different companies out there. With Aventon being a 10 year old company made in America, with distributors/ verified mechanics all across the US (including Mississippi thankfully for me!!) it seemed like a no brainer. The community of Aventon riders, design and craft of the bike, and the attention to detail is what will make me a customer for life! I get SO many compliments on it and with the fat tires I can truly go anywhere I want! The only thing that would make it better is if it could be just a few pounds lighter, and if the app connected with my original account (I don’t get how you can use your mileage rewards if it doesn’t transfer from the bike/app). Overall, I would highly recommend this bike if an electric bike would work for you Flashe!!!

  43. Dreymond Powers

    Ordered and received two sinch ebikes in white. The paint is beautiful and gets alot of compliments. A local bike shop assembled and added the fenders, bike rack, dog basket, mirrors and lights all for just 30 dollars. Wow what a deal☺️. The bikes ride smooth and just alot of fun to ride. We love the bikes and so do our two tea cup york🐶🐶 I would recommend to family and friends

  44. 🤞

    Great little bike for short rides

  45. Malbemaro Setri

    Has given back freedom to ride

  46. Fisher Drubna

    Just buy it.

    What an incredible value for your money. Everything about this bike feels like it should be on a more expensive bike.

  47. Dren Albis

    If you’re considering getting a foldable ebike, look no further!

  48. Abena Tratolito

    Plenty quick, solid range, excellent build quality

  49. Lowa Sinch

    The ease of riding a step thru has changed my exercise routine. We are buying one for our 16 yo granddaughter.
    My husband and I have been super impressed with the Aventon products and highly recommend purchasing an ebike with this company.

  50. Neremiah Sanders

    SINCH BIKE Is truly a remarkable Ev BIKE that is unique in design and style. I give it’s ratings a 5 STAR for its quality in the making of future bicycle analysis

  51. Cheri Fadrold

    I love the foldable Sinch. It especially comes in handy when I take my car in for service that I fold this into my back and take with me to ride back home. I especially ride this bike on the dirt and hilly trails around my neighborhood since the tires are 4” wide. It has lots of power, fast, and fun! I highly recommend any Aventon e-bikes as I already have 3 of them with the Sinch being one of them!I love the foldable Sinch.

  52. Una Serah

    Really well designed! We got a red and green. The area in Michigan that we use them is very hilly and they have no problem. Only thing I might consider other than the $200 in accessories that came with (lights, racks etc.) is a seat upgrade. My wife and I are both fatigued in that area after about 10 miles.

  53. Cornelius Alna

    This is an amazing Ebike that you can take anywhere

  54. Angelo Des

    Never better

  55. Hisrtern Can

    So far so good. Took it on some trails and it did great was fun. Was a little slick but I was able to keep control. The tires dug in and got me thru it. Bike seems well put together. Was able to fold it and stow it in my camper along side my bed while traveling.

  56. Luke Brendan

    Perfect combination of power, range and portability. Cannot overstate the importance of the dead stop throttle – this is huge when trying to get any of these 70ish pound e-bikes moving up hill. This is included on the Sinch and is advertised on their page – I couldn’t find a foldable bike with similar advertised specs from other makers. The 750W motor can also get my 200lb butt up a fairly steep grade using throttle alone. This will obviously use more battery and decrease range, but it’s nice to know it can do it.

  57. D.H

    the best move i made! I have an Enduro motorcycle & the SINCE is more fun I drive it all over North East PA ON AND OFF ROAD. They are so well built and durable… people out there looking to get one I’ll be the first to tell ya buy one cuz u will enjoy it!!! Absolutely love my SINCH

  58. Verala Shubon

    This e-bike has surpassed my expectations. I would highly recommend it.

  59. Kylian Adam

    I really love my new Sinch ebike. Everytime i used it a lot of people seeing it saying it is a very nice ebike. It is comfortable to ride & really fit on me. I enjoy the ride at my Aventon electric Bike!

  60. Rock C

    This bike is pretty amazing!! The quality of the built on this bike is great!!! Easy to ride and the onboard computer is very easy to read. Love the fact that you can hook up your cell phone to your bike’s computer via an available app you can down load.
    The bike rides very smooth. It has a very solid feel to it. I like the way it looks and handles. I highly recommend this bike. It’s a great deal for the buck!!! I will easily give this bike a 5 star rating!!!

  61. Marks Dublon

    I have a bad back 3 surgeries so for me to be on a treadmill or in a gym its hard. Not only boring to be in a gym or treadmill but hard if my spasms kick in or my back pain or right leg gives out. The Sinch bike gave me life to be outdoors again to exercise and enjoy it.

  62. Owen Gibeera

    So far it’s great! Did a lot of research and the sinch step through has met those expectations for sure. Definitely scratches the kickstand when you fold the bike so be careful. Handles well though and the assembly videos were great. I’ve put 130 miles on it so far.

  63. Lookman

    Great bike really enjoying it

  64. Rati Ryler

    I was amazed by the speed of this eBike even up steep hills. It also fits folded in my little Fiat 500.
