Though the Sinch electric folding bike has been a mainstay in the Aventon lineup for some time, this step through version is a new beast.
And by new beast, I’m not just saying Aventon lowered the top tube and called it a day, I mean the new Aventon Sinch ST is, for all intents and purposes, an entirely new e-bike.
There are some similarities between the two Sinches, mainly that they both use Aventon’s 500W rear hub motor and are powered by a frame-integrated 48V, 14Ah (672Wh) battery, but many of the similarities stop there.
The new Sinch’s overall look is much different from the old bike. Its step-through frame uses entirely different boxy tube shapes that are much more similar to the Aventon Aventure electric fat bike than the sharp and ovalized tubing we saw in the high-step Sinch. Its battery is also accessible without cracking open the frame. Like the Aventure and the new Pace 500, the battery is easily removable via a latch and key mechanism.
Aventon also redesigned Sinch’s frame closure mechanism and seemed to really beef up the hinge. It still works much the same way, but the latch is much more aesthetically pleasing and, at least in my opinion, a little more confidence inspiring. Though the folding mechanism has been tweaked, Aventon still has not given users a way to secure the two halves of the bike together when it is folded, leading to some potentially floppy maneuvering should you have to lift or move the bike. The addition of a small rubber strap to tie the two halves together would solve this issue, but alas, Aventon and many other makers of affordable electric folding bikes don’t include this with their bikes.
Other new (and highly visible) spec on the Sinch Step-Through are its 4-inch tan wall semi-slick tires made by Chao Yang, a relatively unheard of tire brand. These obviously do a lot for the bike’s look, but the semi-slick tread pattern is also a change from the old Sinch’s more off-road oriented Kenda knobbies. I’ll dive into more about how these tires changed the Sinch’s handling, but the quick and dirty of it is I prefer these new tires to the old ones — they roll better and make less noise on pavement, the surface this e-bike will likely spend most of its time.
But, in all that is new, there are some things that have not changed. The Sinch’s drivetrain is still a 7-speed (in the case of our review model, a Shimano Altus setup), we still have mechanical disk brakes and the weight is unchanged at 68 lbs.
