Aventon could have simply lowered the top tube and called it a day, but instead they gave the bike a full ground-up redesign for its step-through debut.

We love the updated looks. It’s very similar to the other new e-bikes Aventon has released over the past year.

The climbing ability is extremely impressive, especially for a bike with a 500W rear hub motor.

The Tektro mechanical disk brakes work impressively well, earning a top-5 spot in our brake test.

The redesigned folding mechanism works great, is confidence inspiring and silent — the folding bike trifecta.

Tan wall tires. ‘Nuff said.

The battery range is solid; right in line with what we’d expect.

It uses Aventon’s new(ish) full-color LCD display, which is one of the most functional and aesthetically pleasing displays in the affordable e-bike category.

As with many folding e-bikes, larger riders may feel a little cramped.

The throttle felt a little soft when starting from a dead stop. I sometimes felt the need to give a small “scooter” kick to get going quicker.

There is a small lag between when you start pedaling and when the motor kicks on, which isn’t terribly uncommon among affordable e-bikes.

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
