4 years agoVery 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.
ReplyTyson Roehrkasse
4 years agoHey 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.
ReplyDrJay
4 years agoThanks 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.

4 years agoHi 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

4 years agoUpdate to the throttle issue. As of March 2021, they changed this and now this bike has “throttle on demand”.
ReplyDrJay
4 years agoTricia, thanks for that update. It makes a huge difference to me in the performance.

4 years agoGreat 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.
ReplyThanks for the great/honest reviews!
Tyson Roehrkasse
4 years agoHowdy 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 :)

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 :)
ReplyMike
4 years agoThat’s great! Yes, please let me know! Thank you for looking into this
Mike
4 years agoI 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.
DrJay
4 years agoMike, 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.
ReplyCourt
4 years agoHi 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 :)
ReplyDrJay
4 years agoThanks 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.
Dave
4 years agoThanks 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.
ReplyTyson Roehrkasse
4 years agoHey 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!
ReplyDrJay
4 years agoDave, 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.
ReplyTroy Robinson
4 years agoThank 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,
ReplyTroy
Tyson Roehrkasse
4 years agoSadly, not on any folding bikes I have ridden so far :(
I’m still holding out hope that someday I’ll find one!
ReplyTroy Robinson
4 years agoThanks 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.
Rodney
4 years agoI 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.
ReplyTyson Roehrkasse
4 years agoHi 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!
ReplyRodney
4 years agoHi 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
4 years agoI 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?
ReplyTyson Roehrkasse
4 years agoHi 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.
ReplySeif Ali
4 years agoThanks for the reply, I have another question maybe you can help me out.
Theres an e-bike called the overfly hummer that you can buy on Amazon. It seems to me like it’s the same frame as the Aventon Sinch. It’s $450 cheaper but doesn’t have front suspension forks. I saw that you can buy the suspension on the Sinch forks separately from the manufacturer of these suspensions for $150. My question is, can I buy the Overfly and buy these suspensions and install them myself? I like the fact that the overfly has a right twist throttle as well.
Doug
4 years agoAre you sure the reach on this bike is 27”, that seems excessive?
ReplyTyson Roehrkasse
4 years agoHi Doug! That is the correct reach, we measure this from the seat post to the middle of the stem column (just above the headset). There are a lot of different methods for measuring reach out there, this is the one we use on every bike to help with comparing them.
ReplyDemetrius
4 years agoSo I understand the bike is 500 watt motor but they say the peak is “750”. Are they saying you can unlock the motor to a 750? Can someone explain please?
ReplyTyson Roehrkasse
4 years agoHello there! This means that the motor typically draws 500 watts of power, but it is capable of drawing extra power for a short burst, or “peaking” at 750 watts. You don’t have to unlock or change anything for it to happen. I’m not an expert on the differences between nominal and peak wattage, however, but your comment is now showing here so hopefully we can get some more folks to chime in :)
ReplyAdam
4 years agoOverall a great package – rides well and has attention grabbing looks with a good clean shape and rich looking finish. I put on the fenders and the rear rack which is very sturdy. Wish they had a front rack and more accessories for the racks and the unique shaped frame. Fun to ride, but it feels safe primarily because it is hefty and not over-powered. There is a delay in the PAS modes with the throttle when already moving and it does not work unless underway so I prefer to keep it in 0 PAS with throttle bursts available for city and tight maneuvering (keeping it in 3rd or 2nd gear to get easy starts. Walk mode works, but there is a delay with this “cheat” so it can feel awkward as it is hard to figure out when the acceleration will kick and when it does it feels like an old school Porsche 930 Turbo – plus you will not be sitting properly on a bike from standstill. PAS is best for longer stretches and this kicks in pretty strong. On downhill it is easy to get up to 30MPH with PAS and some quick peddling, but the gearing maxes it out there so it is not a fast bike, but rather quick. It’s the Mercedes 280SL of bikes. It feels solid as a tank with steady power delivery, can handle any road with poise and style and all while being reliable and offering enough cargo for a weekend, but not a voyage…
Replyla woodard
4 years agoHow much does the aventon sinch weigh and could you ride simple mtn bike trails on it?
ReplyTyson Roehrkasse
4 years agoThe weight is 67.6 lbs (30.66 kg) and you could do some simple trail riding, that is to say, the bike could handle it although it won’t be as maneuverable as a mountain bike. You would also want to make sure ebikes are allowed on the trail as some mountain bike trails don’t allow any electric assistance!
ReplyMARK REICHOW
4 years agoI recently got a screaming deal on an almost new Aventon Sinch with 56 total miles on it. As this is my first e-bike I don’t have much to compare it to, but I LOVE IT! The throttle issues that many are concerned about don’t bother me a bit since this is all I know. Works great, but I do understand both the tradeoffs and benefits of each method of dealing with the throttle. I’ve only been able to put on 20 miles so far but I’m really looking forward to playing more with this new toy as soon as the weather allows.
ReplyCourt
4 years agoSweet! Sounds like you’re enjoying the bike, that’s wonderful to hear Mark! Thanks for the update and congrats on the good deal :)
ReplyMark Reichow
4 years agoIf anyone is looking for a rear rack that is made for this frame, the rack offered by Overfly for their XY-Hummer (exact same frame as the Sinch) is a great match at a fair price. It took a bit of very minor tugging and pulling to get the screws in, but once they’re started it’s an easy job. For $40 shipped you can hardly go wrong. They say “Usually ships within 1 to 3 weeks” but it was California to Wisconsin in 4 days.
ReplyCourt
4 years agoGreat tip, Mark. Thanks for the feedback!
ReplyTodd
4 years agoThere’s also an option to buy the rack and fenders. I just purchased the combo for my Sinch. I’m hoping the fenders are the same as well. Any idea about this?
ReplyMark
4 years agoI have no input about the fenders. I didn’t want typical fenders, or a front fender at all. Instead I cut up an old WeatherTech car floormat and fabricated a rear fender that zip-ties to the underside of the rack and curves down to bolt to the normal bottom mount point of a fender.
David Cameron
3 years agoYou may want to update the “Con” around not being able to access throttle from a standstill. This has been addressed in the 2021 version of the bike. You can now utilize throttle from a standstill. Aventon also offers an upgraded head unit and controller on their site that will upgrade the previous models to allow for this as well. Glad they addressed this!
ReplyTyson Roehrkasse
3 years agoThank you David, this is wonderful news! I’ve updated the cons section accordingly :)
ReplyAndrew
2 years ago21:00 So you have to fold it to remove the battery?
ReplyCourt
2 years agoYes, many folding electric bikes put the battery inside the main tube. In order to access it for removal, you often have to fold the frame and sometimes unlock the pack so it can slide out. Most of the time, you can leave the battery in the frame if you simply want to charge it. There’s usually a pass-through hole where the charger can plug in :)
