Really nice all around, perfect for casual rides and workouts!

Sorry, this review is a bit long. I put some plus and minus points below for quicker reading.
I was looking for a workout that would be gentle on my knees because I have significant knee pain, and a lot of people recommended cycling. As a beginner living in a hilly rural area, I was very intimidated and unsure how to get started, so I looked at e-bikes as a way to help me out and insure I can get home if I over-do it. The Aventon Sinch ST is what I ultimately chose because I preferred to have brakes from a manufacturer I recognized versus some other cheaper e-bikes where the components were usually no-name brand, and the USB port in the screen was a huge plus to me as well because I could charge a headlight (since this bike doesn't come with one) while on-the-go. This e-bike ended up being so much fun it's easy to stay out longer than I had initially intended to. Exercising with a smile! I definitely recommend it.

For me the biggest pluses are:
+ FOLDING - you can bring it to other locations without needing a rack or truck
+ STYLE - the colors on the ST model are really great, I personally fell in love with the green immediately
+ SIZE - the sizing is perfect for a shorter person and why I picked this model over the step-over
+ USB port on the screen, yay
+ SPEED GOVERNOR REMOVABLE - Aventon allows you to take off the 20mph speed governor if you live in an area where you can exceed that
+ QUIET! - this ebike does not make the obnoxious shrill noises you can hear from other hub motors of a similar size, thank goodness. It produces a gentle tone/whine and only when its beginning to seriously assist, ex. above PAS 3 on a good sized grade

- LIGHTS - No integrated lights :( this to me was almost a deal-breaker and I hope future Sinch models have integrated lights
- DELAY FROM STOP - Significant delay for taking off from a dead-stop. Although my model doesn't require me to pedal for the motor to engage, the designers have clearly limited how quickly it can accelerate from a standstill and I wish this could be removed via settings in the display. I know it's a safety mechanism so you can't fly off into traffic accidentally, but as I got to know the bicycle I wished I could use it as a boost to get me across intersections from a stop
- SPEED GOVERNOR REQUIRES APP - It seems that you must use the app in order to remove the speed governor; other ebikes allow you to press specific buttons in a sequence to do so without syncing it to a phone. If there's another way to do so, I didn't see it in the manual

+/- Doesn't come with fenders or rack; not a huge deal but they're nice to have
+/- The throttle itself is a bit strange, but this is likely because I'm used to twist and grip throttles. This model has a thumb throttle on the left hand side of the handlebars
+/- Wish the tires were tubeless ready

Great customer service

Have not had a chance to ride yet but everything is great so far

Brandon Chang
School Commuter

Great little bike that helps me get around campus easier, its small enough that I can bring it inside with me most times to prevent theft, but big enough that the ride quality is great.

Hi Brandon,

Thank you for leaving a review! We are happy to hear this bike has met your expectations, cheers!

300 plus miles

After 300 miles I like it more now than when I first got it. Took it in for its 300-mile check and adjustments and none were needed. Still solid as a rock. I bought a cushier seat but reverted back to the original seat that came with the bike. A few adjustments here and there have made the seat comfortable and does fine on a 28-mile ride. The one thing I would like assistance with is for Aventon to look into my bike rack. I registered my purchase when I first bought the bike and have not received any response.

Hi James,

Thank you for leaving a detailed review! We appreciate the feedback we will forward this to our team.
