Aventon Sinch: A Fat Tire, Folding E-Bike That Fits Under Your Desk

If you’re looking for an e-bike that goes anywhere, even when you’re not riding it, the folding Aventon Sinch and new Aventon Sinch Step-Through are worth a look.

With large, fat tires and a suspension fork on a compact folding frame, these bikes should roll over various terrain, then pack down and store in almost any nook.

With an integrated battery and powerful hub motor, the Sinch lineup is designed to make it easier to ride and store a fat bike.

2 Folding Options

The Aventon Sinch starts with a shaped, double-butted 6061 aluminum frame that hides the battery inside the front half. The battery is removable for indoor charging, or you can leave it in and charge it while installed. It’s a one-size-fits-most frame that accommodates riders from 5’0″ to 6’3″.

The Sinch Step-Through keeps the same features but lowers the top tube, designed to make mounting and dismounting a breeze. Rather than the 5-foot threshold of the base Sinch model, the Sinch Step-Through is suitable for riders starting at 4’11″. It also accommodates riders who don’t want to throw a leg over a high top tube every time.

How the Sinch Measures Up

A single hinge mechanism locks into place to create a sturdy frame while riding. All its cables and wires run internally for a clean appearance and less fuss when opening and closing the frame.

When folded, both bikes can fit under desks, into car trunks, or even a closet. Before folding the frame, you simply unlatch and flip the stem and handlebar down, and fold the pedals flat, yielding a very compact 41 x 23-inch footprint that’s just 31 inches tall.

The Sinch Step-Through is a little wider and longer when folded at 48 x 28 inches. However, it breaks down to be about an inch shorter than its stepover sibling.

A built-in stand keeps the bikes standing upright when folded. At 68 pounds, they’re not light, but you can wheel them around while folded, helping you slip them out of the way no matter where you store them.

Suspension & Power Specs

Up front, a 45mm suspension fork works with the huge 20 x 4-inch fat bike tires to absorb impacts and smooth the ride. Whether you’re hitting those neglected urban streets, rough backroads, or sneaking in some trail time on the commute, these big tires should provide traction and support. And according to the brand, the tires are puncture-resistant, so you’re less likely to be slowed down by a flat tire.

The Sinch lineup has a seven-speed drivetrain, which should give you just enough gear range when combined with the motor’s assist. Aventon claims its 500W 48V brushless rear hub motor moves you along at up to 20 mph and can peak at 750W for power starts.

The brand gave this system an average 40-mile range powered by a big 48V, 672Wh battery. A 48V, 3A fast charger is included to top it off from empty in just less than 5 hours.

Like the brand’s other e-bikes, the Sinch works in two modes: Pedal Assist (with five levels of power to choose from) and Throttle on Demand. The latter lets you press the thumb lever on the left side of the handlebar and scoot along without pedaling.

An LCD display shows speed, mode, remaining battery life, and total distance on the odometer. The Sinch Step-Through features a color LCD display.
