Aventon Sinch Step-Through review

Should you buy one?

Buy the Sinch Step-Through if you want a folding fat-tire bike that fits in a car trunk and still fits a 6’1” rider. It folded into the trunk of my Model 3 (0:40 to 0:59), and with the seat raised it fit me fine (2:42 to 2:59). The 500W rear motor and 4 in tires handled dirt trails even though the tread is street tread (1:53 to 2:24).

Skip it if you want lights out of the box. My bike had no headlight and no tail light (1:11 to 1:26). Also skip it if the price matters most: I tested it at $1,800 with fenders and rack extra (0:22 to 0:35).

The deciding factor: folding. If you don’t need a bike that folds, the Wallke F1 has the same 500W motor size for roughly $800 to $900 less, by my numbers in the video (10:21 to 10:42).

I rode this bike for a three-bike comparison, not a full solo review. You can read the Sinch ST vs Cyrusher XF900 vs Wallke F1 comparison for how the three stack up.

See the current Sinch.2 at Aventon (the Step-Through I tested is discontinued; the Sinch.2 was $1,799 and sold out on aventon.com as of Oct 22, 2026. Affiliate link; it doesn’t cost you any more.)

Quick specs

Source note: times in parentheses are from my comparison video. Everything marked (Aventon) is from Aventon’s Sinch Step-Through launch post and owner’s manual. The queue called this bike the “Sinch 2,” but the bike in the video is the first-gen Sinch Step-Through.

What I didn’t test

I didn’t run a range test, a top-speed test, or a braking test on this bike. I also didn’t weigh it or test the suspension on rough ground. Every range, speed and weight number here is Aventon’s.

Who it’s for

• You need to fold a bike into a car trunk (0:40 to 0:59).
• You’re tall. It fit me at 6’1” (2:42 to 2:59), and the handlebars adjust (3:15 to 3:21).
• You want a throttle that works from a stop (3:01 to 3:11).

Who should look elsewhere

• You ride at night and don’t want to add lights (1:11 to 1:26).
• You don’t need folding and want to save money. See the Wallke F1 below.
• You want hydraulic brakes. This one uses mechanical discs (Aventon).

How it compares

Rival specs are from the brands, as listed on my review pages for those bikes.

The step-over Sinch is the same idea with a different frame. The Rattan has more motor for less money. The XP4 is the lightest and cheapest, with narrower tires.
