    Cyrusher Kuattro Review: E-Bike Overview

    Like Cyrusher’s other fat tire electric bicycles, the Kuattro is a well-rounded bike that delivers outstanding all-terrain performance. Whether it’s used for the daily city commute or off-the-beaten-path exploration, the Kuattro is a fun ride that’s always up to the task.

    The 26-inch by 4-inch fat tires offer up a comfortable ride and provide plenty of grip for muddy trails, sandy beaches, snow, and gravel. The lockout front fork suspension also contributes to the Kuattro’s comfy handling and does a fine job of absorbing rough bumps.

    Powered by a 750W BAFANG rear hub motor that produces 1200W of peak output and 80Nm of torque, the Kuattro dishes out plenty of speed and power for uphill climbing and off-road adventuring. The nicely integrated waterproof battery is neatly hidden in the bike’s downtube and delivers 50 miles of range on a single charge.

    The Kuattro also comes with a bright 250 lumen LED headlight and taillight for safety and increased low-light visibility, and the front and rear fender set do a nice job of shielding the rider from water and mud.

    Mounted to the rear of the bike is a durable cargo rack that makes it easy to attach pannier bags or supplies. Lastly, the included Star Union hydraulic brakes are dependable and deliver the type of top-shelf stopping power that is required for a bike of this size and weight.

    Size and Weight

    The Kuattro is a big, tall bike, weighing in at 74 lbs (66 lbs without the battery) and measuring 76.3″ in length. It has a 47.6″ wheelbase and the saddle is adjustable from 34.6″ to 42.5″. If the Kuattro’s large size is an issue, we’d recommend checking out the more compact Kommoda step-through model or the lighter XF650 (61 lbs).

    Performance and Ride

    As you’d expect, the ride quality of the Cyrusher Kuattro is outstanding. This is a comfortable bike that handles extremely well, and there’s plenty of power under the hood for things like hill climbing and challenging off-road terrain. The bike’s geometry also makes for an enjoyable riding position, and the convenient step-through frame makes mounting and dismounting effortless. For those who prefer an e-bike with dual suspension, be sure to check out the Cyrusher XF800XF900, and folding XF690 which all add a rear shock for added bump absorption. 

    Build Quality

    Cyrusher’s electric bikes are well-built, and the Kuattro is no exception. The bike is nicely constructed and features high-quality components and the type of finish you’d expect to see on a bike in this price range. Cyrusher also does a great job of securely packing their bikes for shipping, and the Kuattro arrives well-packed and ready for assembly.


    Like Cyrusher’s other electric fat tire bikes, the Kuattro is a bold-looking ride that’s sure to attract attention. Currently available in two colors (Cyan and White), the Kuattro’s massive fat tires, front suspension fork, and rear cargo rack tell onlookers that this e-bike is all business. 

    Included Accessories & Optional Add-ons

    Included with the Kuattro is a tire pump, assembly toolkit, fender kit, charger, and rear rack. Cyrusher also sells a lineup of e-bike replacement parts and add-on accessories through its online store, including rearview mirrors, batteries, saddles, pannier bags, and more.

    Warranty & Customer Support

    As mentioned, Cyrusher goes above and beyond most of the other consumer-direct electric bike manufacturers when it comes to warranty coverage. All Cyrusher e-bikes come with a 2-year warranty which covers customers in the event of a manufacturing defect. Cyrusher also provides customers with a 14-day return policy and the company doesn’t charge hefty restocking fees like many other brands.

    Cyrusher’s customer support department is easy to reach, and you can contact the company via live chat, phone, and through a website contact form. At Recharged Rides, part of our e-bike ratings process involves testing the responsiveness of each brand’s customer service, and we’re happy to report that Cyrusher outperforms many other companies in this regard, taking only a few hours to reply to submitted inquiries…
