Aventon Sinch Review: Takeaway

The Aventon Sinch folding electric bike is a great e-bike for getting about the city. And as a bonus, it folds up compactly so you can store it in tight spaces.

When you’re riding between your RV or apartment to town or work and don’t have to do much carrying, the Sinch is a great little e-bike thanks to its power and compact size. The machine is quick and powerful, and even for larger framed individuals, a comfortable ride. Easy to fold and unfold ready for riding, the Sinch really is a cinch to use!

Ideal for...

RV holidays

City riding/commuting where space is a premium

Light off-roading

Utility riding with cargo

Aventon Sinch Overview

When choosing an e-bike for off-road use, it’s helpful to have features such as an aluminum frame, suspension fork, and heavily threaded fat tires. These help the Sinch absorb most of the bumps it encounters, giving you a smoother ride even on the roughest terrain.

Foldable e-bikes are often marketed toward smaller riders, such as teens or shorter adults. However, the Sinch can comfortably accommodate riders up to 6’3” tall. The model is also available in a step-thru frame for shorter riders.

The Sinch’s frame-integrated battery is highly beneficial for a number of reasons. Firstly, it protects the battery from the elements (such as rain or dust) while also distributing the weight more evenly for a smoother ride. Additionally, this stealthy placement of the battery can decrease your risk of battery theft — although the e-bike’s foldable nature means you’re less likely to have to store it in public, anyway.

The e-bike’s five levels of pedal assist allow you to cater your riding experience to your preferences, whether you’re looking to cruise over hills or put in some hard work.

Reasons to Buy

Since 2021, Aventon has converted all its bikes to an on-demand throttle, including the Sinch. That means instead of needing to pedal at least a quarter rotation, you can start the throttle from a dead stop, making it easier to climb hills from a standstill.

It’s hard to look past the versatile, foldable, and portable nature of this e-bike. The model is perfect for commuting, urban biking, or hitting the trails and can be folded up afterward for easier and more compact storage. The Aventon Sinch is also one of the only foldable fat-tire e-bikes featuring a fully integrated battery.

The model’s inclusion of a backlit, full-color LCD display is also a huge benefit. Not only is it easy to read at a glance, but it contains helpful information about your trip, such as speed, battery health, level of pedal assist, and distance traveled.

Things to Consider

Despite its convenient folding frame, the model doesn’t have a latch function for keeping it securely in a folded position. While this isn’t too inconvenient if you’re only folding your Sinch for storage, it may impact those folding their e-bike for traveling on public transport.

Rear hub motors are known to be slightly noisier than other motor types. While the noise isn’t particularly loud, it is noticeable when the Sinch is riding at slower speeds.

Ratings

Power

 4/5

The 500W motor can reach a top speed of 20 mph — perfectly adequate for most needs. Because the motor is a rear-hub system, you’ll struggle on hills. This is because it is a direct drive on the rear wheel, whereas a mid-drive system would put the power through the bike’s pedal gears.

Acceleration will be relatively slow owing to the rolling resistance of the small, fat tires. However, the added grip will mean it can handle off-road routes better on muddy and loose substrate.

Range

 3.5/5

3.5

At full power, the Aventon Sinch can run for just under an hour. Since most riders won’t power at the top 20 mph speed for a full hour at a time, we’re inclined to accept the range claims by Aventon (average 40 miles per charge on throttle alone). Expect even more miles on pedal assist, as most riders move up and down the power settings as part of normal riding.

Aventon’s measurements are based on a 160-lb rider on a flat surface. Unless you’re in the Mojave Desert, you’re unlikely to be able to travel on the flat for 40 miles! Hills, headwinds, rider weight, surface conditions, and weather conditions will all impact range.

Comfort

 3.5/5

3.5

Being a one-size-fits-all bike, the Aventon Sinch Foldable e-bike may not be comfortable for smaller or larger riders. Though Aventon says a 6’3” rider can ride it, they may be a little bunched up with their knees bent and shoulders leaned over, even after raising the handlebar and saddle heights.

With a 42 mm travel front fork and fat, 4” tires, this bike will handle rough terrain well. It won’t be much fun for a BMX track due to its weight (despite its appearance), but it could certainly be taken into the woods on an RV vacation.

Durability

 4/5

Thanks to the rear-hub motor, this e-bike will have minimal maintenance issues. Chain maintenance will be sometimes less frequent than on a traditional bike, especially if you use the throttle most of the time.

If pedal assist is your preferred riding style, check for chain stretch and replace the brake pads every 800 miles or so. Oil the chain regularly. The good news — Aventon offers a lifetime warranty on the frame and a year on all other parts.

Style

 3.5/5

3.5

With the interesting upward curve of the main frame, you could almost call the style idiosyncratic. Beauty is in the eye of the beholder, and while this bike isn’t ugly, it wouldn’t win design awards.

The gray and black color scheme is nice enough, and its BMX-style appearance adds to a certain cuteness. Otherwise, it’s a well-proportioned and good little electric bike.
