The new Aventon Sinch may seem like an unlikely combination of features, but it’s all about getting more people out on bikes. Building off the success of their existing Sinch folding e-bike, the new Sinch Step-Through makes the bike even easier to ride and somehow manages to make it look better in the process.

Compared to the current Sinch, the most visible update has been the inclusion of a step-through frame design made from 6061 aluminum alloy. Coupled with 20″ wheels and 4″ wide tires, the step-through frame presents a very low barrier to entry–literally. Riders that may have trouble stepping over taller frame tubes will have a much easier time mounting and dismounting the Since Step-Through.

And those wide tires should provide a confident footprint both offroad and on.

Perhaps more impressive is that Aventon managed to combine the low step-through design with a folding e-bike platform. No bike rack on your RV? Want to carry a bike in your boat? No problem, just fold it up and store it inside (assuming you can lift the 68lb claimed weight of the bike, of course).

Folding up the Sinch Step-Through is a simple affair, with a single latch just below the battery on the downtube.

There’s also a release latch on the steerer tube extension that lets you fold down the handlebars. For even more compact storage, the pedals fold in as well.


Aventon Sinch Step-Through Sizing and Geometry

Offered in a single size, Aventon claims the Sinch Step-Through will fit riders from 4’11” to 6’3″. Even with the handlebar at the lowest setting, the Sinch has a very upright position geared towards comfort rather than performance.

Equipped with a 500W brushless rear hub motor, the Sinch Step-Through provides pedal assist up to 20mph. For the size of the bike, the battery is an impressively large 672Wh and includes LG Lithium-ion cells. Using the 3 amp fast charger, recharge time is about 4-5 hours and should provide up to 40 miles of range on average.

The Sinch also includes an impressive LCD color display that can be connected to the Aventon App for further functionality.

The Letric Vs the Sinch? No comparison. The Sinch is a much beefier better built bike than the Letric. Sinch has a bigger battery, that equals more mileage. The Sinch is much better at climbing hills. The Letric is a week sister. I had an Letric.. put 20 miles on it and sold it. Bought the Sinch and I’m much happier with it. Ya get what you pay for.
