  • The Aventon Sinch is a value-priced fat tire folder with a beautiful visual appearance thanks to internally routed cabling and paint-matched components, Kenda Krusade tires can tackle any terrain and include puncture resistance
  • A 500 watt motor from Shengyi provides satisfying power and is activated via either a thrumb throttle or the sealed cadence sensor, spring suspension fork from RST provides a smooth ride experience, and the telescoping stem extends high enough to fit tall riders
  • The Shimano Acera derailleur is a great step up in quality and provides a satisfying shifting experience with rapid-fire trigger shifters, mechanical disc brakes from Tektro give solid stopping power and include motor inhibitors, optional fenders are sturdy and provide full-length coverage
  • The throttle cannot be activated while stationary which can be a challenge when combined with the limited range of the 14-28 tooth freewheel, no accessories are included but many good ones are available as optional add-ons

Written Review

To run the forums, host the website, and travel, I charge a universal service fee for my reviews. This in-depth review was sponsored by Aventon. My goal is to be transparent and unbiased with you, this video and writeup are not meant to be an endorsement of Aventon products. I welcome your corrections, additions, and feedback in the comments below and the Aventon electric bike forums.


  • Aventon started in 2013 making fixed-gear bicycles, and over the years they have steadily grown in size and turned to focus more and more on the Ebike space
  • The Sinch does not allow you to activate the throttle while pedaling, activating the throttle while pedaling will give no response which can be a bit confusing if you’ve ridden other Class 2 Ebikes that allows both at the same time. UPDATE: I discussed this issue with Aventon, they told me that you should be able to use throttle while pedaling on the Sinch. I also called an Aventon dealer about it, and they confirmed what Aventon said, which is that the throttle should work while pedaling. The bike I used for this review was a floor demo bike, so it’s possible that the settings got messed up at some point, but you can see me demonstrate the behavior at 35:15 in the video review. If you’ve ridden the Sinch and can comment on the throttle behavior while pedaling, please chime in by leaving a comment below and let us know how it worked :)


  • Two beautiful color options, available from a growing network of dealers that makes it easy to test ride and get fitted, and backed by a great warranty with one year of comprehensive coverage and an impressive lifetime warranty for the frame
  • The Sinch has a sleek and beautiful appeareance, Aventon really knocked it out of the park in terms of cable management and visual design, I appreciate the thick and sturdy wraps on the control cables, internally routed cabling, and the paint-matched fenders
  • Ride comfort is excellent even for larger riders like myself at 6ft 3in, helped by the wide saddle, RST suspension fork with 45mm of travel, and of course the fat tires – that high volume of air is great for absorbing bumps in the road. I also like that Aventon didn’t skimp on the length of control cables which allows the handlebars to be raised nice and high, this made it easy for me to achieve a nice upright relaxed riding position
  • Speaking of the tires, these Kenda Krusades have a nice thick tread pattern that does great with riding offroad and on virtually any terrain, even sand and snow are no problem if you lower the pressure down to 5-10 PSI. At 20″ x 4″ these do add some weight to the bike, but the smaller diameter means a nice mechanical advantage for both the rear-hub motor as well as for the brakes
  • The motor is a 500 watt geared rear hub motor from Shengyi, this is actually the same motor as is used in the Aventon Pace 500, just in a larger motor housing to accommodate for the larger hub spacing of the fat tire setup. This motor already felt good on the Pace and it feels much more powerful here thanks to the aforementioned mechanical advantage of the smaller wheels, hitting the throttle provides satisfying acceleration and quickly accelerates up to the max speed of 20mph. Since this is a Class 2 Ebike the speed is capped at 20mph, but the motor is actually capable of reaching higher speeds, and it is possible to configure this bike to reach those higher speeds with pedal assist only (talk to Aventon support or your local Aventon dealer if you’re interested)
  • The drivetrain here is high-quality and features the Shimano Acera derailleur, this is a great derailleur that is several steps up the Shimano line in terms of quality. The freewheel is fairly basic with only a 14-28 tooth range but this is sufficient for the expected use case of the Sinch, especially paired with the large 52-tooth steel chainring, and I appreciate that the chainring has a full double-sided alloy guard that keeps it clear from debris as well as protecting it. Shimano rapid-fire trigger shifters on the right grip are satisfyingly clicky as always
  • The charge port is positioned high up and forward on the frame which is great to see, this helps to minimize the risk of damage as the cord is less likely to get tangled in the crank arms if the bike is moved or knocked over while charging
  • The cadence sensor here is high-resolution with 12 magnets and it is a sealed sensor, much more resilient than unsealed sensors which can get bent and have magnets knocked out. I appreciate the fact that full-throttle power is available from any assist level as well, allowing you to quickly accelerate even if you were riding in assist level 1
  • The kickstand is sturdy with a wide base, adjustable for length, and rear-mounted where it won’t be at risk of locking up against the crank arms
  • If you’ve read any of my reviews you’ll know that I love grayscale LCDs for their high visibility, and I absolutely love Aventon’s display – not only is it a large grayscale LCD, it also has nice big readouts, and the battery readout is a full 10 bars providing precise 10% increments, it is also adjustable-angle which helps to reduce glare
  • Tektro MD-810 mechanical disc brakes provide good smooth stopping power, 180mm rotors dissipate heat well, and the large four-finger levers provide a nice mechanical advantage when actuating the brakes. They also include motor inhibitors to cut power to the motor immediately, much appreciated here since there is a typical delay between when you stop pedaling and when the cadence sensor responds
  • Aventon uses great quality 18650 cells from Samsung in their batteries, and the battery here is a high capacity one at 672 watt-hours, smoothly integrated into the frame, and features an LED readout for showing battery level as well as a carry handle on the top. You can charge it on or off the bike, do pay attention when you remove it – once unlocked it slides out very easily!
  • The frame feels rock-solid with no noticeable frame flex, I was able to easily ride no-handed even when cruising at 20mph
  • It folds! Folding is great for portability as this would be an excellent Ebike to bring on camping or other outdoor trips, and it’s also nice for storing the bike indoors without taking up as much space


  • The review model had fenders equipped but sadly they don’t come standard, they are a $74 add-on from Aventon. I do think they’re absolutely worth it, these are some great quality fenders with full coverage, durable alloy construction, and look great with paint-matched colors
  • The Kenda Krusade tires don’t have any puncture protection so I recommend adding some of your own as changing flat tires on a fat tire bike is not a fun time! There also is no reflective striping on the sidewalls which means less side visibility, if you ride in high-traffic areas I would recommend getting the Crest White frame color for better visibility
  • The throttle cannot be activated from a standstill, you have to start moving by pedaling first, and then once you get up to 2-3mph you can switch over to the throttle. This can be frustrating if you need to start riding on an incline
  • The freewheel has a range of 14-28 teeth which is a fairly limited range, it does well for the Sinch use case, I think the only real downside to it here is the previous point of not being able to use the throttle while stationary. Normally, a limited gearing range is mitigated by being able to start out with the throttle, and then switching over to pedaling once you get rolling. That isn’t an option here, unfortunately, but realistically you’ll only need to pedal for 1-3 revolutions on the crank arms before the pedal assist will kick in and help you out
  • The Sinch is only available in one frame size, so it may not be a great fit for all riders… but to be honest, I was impressed with the feel of the bike, as a tall rider I typically find folding bikes to feel much too small for me. The Sinch felt great thanks to the wide saddle, fairly large frame, and high range for the telescoping stem, really the only downside was that I wasn’t able to get full leg extensions, keep in mind that is virtually impossible for me on any folding bike
  • Mechanical brakes are reliable and easy to maintain but they do have some downsides compared to hydraulic brakes, these downsides include requiring more frequent maintenance to tighten the cables, and more grip strength is required to actuate them, fortunately, this latter point is a minor issue here thanks to the mechanical advantages offered by the four-finger levers and the smaller diameter wheels
  • Neither the display nor the battery have any USB ports for charging other devices, this is certainly not a necessity, but it can be a nice convenience feature if you like to use your phone for music or navigation while riding
  • There is no latch or magnet mechanism for holding the bike in the folded position, and it is still quite heavy and unwieldy while folded. This is to be expected as you can’t really make a lightweight folder that also has fat tires, just keep in mind that this is not a folder that you can fold up and bring with you on the bus or train
  • No other accessories like lights or racks are included, fortunately, these are easy to add thanks to provided mount points, and Aventon has a large selection of competitively-priced accessories that you can add on when purchasing. Not including them by default helps to lower the price of the Sinch which is certainly appreciated if you don’t need any of those accessories, or if there are specific ones that you want to use as opposed to whatever generic ones might have been included otherwise
  • The display is non-removable which means it is vulnerable to damage if left outside in harsh weather, or if bumped by other cyclists at a bike rack, fortunately, these displays have proven to be quite durable on Aventon’s Pace models

Very nice thorough review. It’s a beautiful bike. I would consider buying this vs a Rad Mini as I have a local Aventon dealer but, for me, the throttle configuration is a deal breaker. It’s a heavy bike and to need two to three full pedal revolutions before the throttle is active makes crossing an intersection from a dead stop more dangerous than it should be. While riding ,not being able to pedal and use the throttle just means that you are drawing more “juice” form the battery. On my Qualisports I often use the throttle for a short burst while pedaling up a hill in PAS level 3. I’m able to maintain speed with pedaling and only partially engage the throttle. Possibly I’m missing something but I don’t understand or appreciate that configuration. I could probably get used to it but not being able to throttle from a standstill…too dangerous especially if one has forgotten to downshift to a very low gear.

Hey there DrJay, thanks for commenting!

I feel you on the “no throttle while pedaling” configuration, it was strange to me as well… but once I got used to it, I think it’s totally workable. You just have to increase the pedal-assist level to get that extra power from the motor, instead of hitting the throttle while pedaling. It’s different than what a lot of people may be used to and going for the throttle may be more intuitive… but I find the setup on the Sinch is still fully functional, just have to get used to it being a bit different.

Thanks for your comprehensive reply. I understand that this throttle configuration is “workable” and one can get used to it but that doesn’t take away from the fact that it is a poor configuration from a company that produces the 500 and 350 that do not operate that way. I have read a lot of reviews on EBR (love the site and appreciate all involved) and this is really unique. I have ridden the Aventon 500 and while it does require at least one full pedal revolution to engage the throttle (actually almost 2 revolutions on my neighbor’s bike) one can use the throttle while pedaling. So why has Aventon abandoned that operation? It really makes the motor/battery less efficient. Manufacturers want to sell bikes and if Aventon gets enough negative feedback hopefully they will change. My LBS is an Aventon Elite dealer and Qualisports dealer and can get this bike. I was really interested in riding it vs having to online order Rad or Magnum. I may go back to considering the Qualisports Beluga that was well reviewed by Court. But this throttle issue is “a bridge too far”. Too bad really. Because in many ways it is an elegant design.

Hi there,

I’m discussing it with Aventon and it sounds like the bike I used for the review may have been misconfigured. They had some guys at the warehouse test them and reported that the new ones do allow you to use throttle and pedal assist at the same time.

The bike they lent me for the review was a sort of demo/show model, I think it got the settings messed up at some point, possibly by another test rider poking around in the advanced settings. I’m waiting on final confirmation from Aventon before issuing a correction to the review, I’ll reply back here once I hear from them :)

Thanks Tyson. This is what i love about EBR: the ability to make comments or criticism and have them taken seriously. Great idea to followup with Aventon. And kudos to Aventon for exploring this issue. Stay safe. DrJay

Great review! you guys are awesome! I was ready to purchase the Aventon Sinch but was put off by the throttle not working while peddling. Ive owned/built ebikes in the past and love peddling hard with throttle to reach high speeds. Is there any way this can be bypassed? Or what other folding bikes do you recommend? I dont have a garage at the moment and would love to save some space in my house.
Thanks for the great/honest reviews!

Howdy Mike!

I’m not aware of a way to bypass that setting, although I’m not an expert on tinkering with this particular display. I will say that you can “workaround” the limit by just adjusting your pedal assist level. If you increase pedal assist up to level 5 it will be the same amount of motor power as if you were pedaling while holding down on the throttle. Not being able to activate the throttle while pedaling takes some getting used to… but it doesn’t limit you in terms of how much assistance you can get from the motor :)

Hey Mike,

I have been discussing this with Aventon, and it sounds like the bike I used for this review may have been misconfigured. It was a demo/test bike, and I think some other test rider might have changed things while poking around in the advanced settings.

Aventon had some guys at the warehouse test a new Sinch and confirmed that it does let you use the throttle while pedaling. I asked them if they could confirm the issue on the demo bike, once I hear back from them I’ll reply back here and update the review as well :)

I just got off the phone with a Aventon rep… The throttle does not engage from stand still, and the throttle cannot be used while peddling. It’s a shame because they would have had my business if it worked like 99% of ebikes. Oh well I’ll keep shopping and reading reviews. Thanks again for all your help.

Mike, I feel the same as you. I love the design esthetic, the power and the features, but that throttle configuration is a deal breaker for me. I just viewed Tyson’s Sondors review and that bike is really interesting at a great price point.

Hi DrJay, I wish we had better details on the throttle action for the Sinch. Tyson said that he called a dealer and Aventon to confirm how the throttle should work, and they both had conflicting information to his experience. So many factors, like did the settings get mixed up for his demo bike or are they misunderstanding his question? I hope this gets cleared up over time, and that they respond to how people would prefer it. I don’t know the exact situation, because I wasn’t there (this is Court speaking btw). Good luck :)

Thanks for your response Court. This is what I love about EBR: the accessibility and the transparency of you and your team. Not to mention all the excellent reviews. It’s my feeling that you have built a reputation with manufacturers and dealers of credibility. I hope my comments are not taken as anti Aventon because they are not. I have friends who own the Aventon 350 and 500 and they are really good bikes for the price. My main bike is a Class 1 mid drive that you reviewed in 2017. I own a Volador for guests that is used to introduce people to ebikes because it is so well programmed and not intimidating. People learn it very quickly. Simple throttle configuration: not active in PAS 0; active in PAS 1-5 including with pedaling. And I think that is more typical of your reviews on EBR for Class 2 bikes. Hopefully Aventon will clarify this issue.

Thanks for your review of the Aventon Sinch. It seems that the bike you tested is configured differently from other Sinch reviews that can be found on YouTube.

I ordered and received a Sinch this past week, April 13th. My bike does allow throttle activation while pedaling. This is a necessary feature since the 14/28 freewheel is somewhat limiting.

In your video review you mention that your test bike had a 13.4 ah battery that was for the demo bike only. You also said Aventon stated the production version will have a 14 ah battery. My Sinch came with a 13.4 ah 46v battery. I would assume mine is a production model.

The Sinch is a fun bike to ride and I’m overall pleased with my purchase.

Hey Dave, thanks for sharing! I’m glad to hear that your Sinch does allow throttle while pedaling, that particular issue has been surprisingly challenging to sort out! I approved your comment and I hope that it helps other prospective buyers with their decisions.

Interesting to note on the battery capacity, I’m going to follow up on that with Aventon. The difference of 0.6 ah isn’t huge… but every little bit counts!

Dave, thanks for helping to clear this up . Hope you have many enjoyable and safe miles on your Sinch. When my lbs reopens I am going to take a test ride on fhe Sinch.

Thank you for your thorough review, Tyson. Like you, I’m also 6’3″. You said ‘it’s virtually impossible for you to get full pedal leg extensions on a folding bike’ Have you been able to do that on any folding bike? If so, which ones?

Thanks again,

Thanks for your response — what about the Voltbike Mariner? Their 2020 model has has max seat height of 40″ and a max handlebar height of 50″. Would that accommodate full leg extension of us 6’3″ people? For details, see Voltbike’s sizing tab here.

I just got my Sinch yesterday. I can tell you throttle does not activate while pedaling. I have to stop pedaling for the throttle to kick in.

Hi Rodney, thank you for sharing that! I’ve heard varying results from multiple Sinch owners at this point… and also conflicting results from asking Aventon dealers! It seems like some Sinch ebikes get shipped with one version of the configuration, and others are different.

I’m now wondering if this is something that can be changed in the advanced settings, although I don’t have a Sinch I can experiment with. If you do experiment with yours I recommend taking pictures of the advanced settings screens before tinkering!

Hi Tyson, after riding it a bit more I discovered throttle DOES work while pedaling but only at PAS level 0. Any other level it feels like it’s trying but it is more subtle, there is no surge. Because of this, I’ll have to say it only works at level 0.

Seif Ali

I heard you cannot use the throttle when stopped . I also heard you can use walk mode instead of pedaling to then use the throttle. can anyone confirm?

Tyson Roehrkasse

Hi Seif, you are correct on both points :) The throttle is disabled when stopped on all Aventon bikes, and some riders work around this by using walk mode to start moving and then switching over to the throttle.
