    Cyrusher XF690 Maxs Review: E-Bike Overview

    A rugged, all-terrain electric bike with a convenient folding frame, the XF690 Maxs features front and rear suspension and large 26-inch by 4-inch tires for excellent off-road handling and performance. A comfortable bike that’s ideal for taller riders, the XF690 Maxs is a feature-rich, full-size fat tire bike that can be easily transported without a large vehicle or expensive bike rack.

    Fun for everything from city commutes to trails, this versatile electric bicycle comes with full fenders and a handy rear cargo rack for attaching panniers or hauling supplies. The ergonomic saddle provides plenty of comfort and cushion, and there’s a bright LED headlight for increased safety during low-light and nighttime riding.

    Packing a 27-speed SHIMANO ALTUS drivetrain and 5 pedal-assist levels, the XF690 Maxs is easy to dial in to a rider’s preferences and the 1000W rear hub motor provides plenty of power for hill climbing and challenging terrain.

    This e-bike also offers excellent range, allowing riders the ability to ride for up to 55 miles on a single charge.

    Stopping power is top-notch, thanks to the bike’s 180mm Zoom Hydraulic disc braking setup, and the front and rear shocks do an excellent job of dampening bumps along stretches of rough terrain.

    Capable of doing duty as a great mountain e-bike or folding city commuter, the powerful XF690 Maxs can handle uphill riding, rough terrain, and long-distance urban commutes with ease.

    Size and Weight

    A big, tall electric bike, the XF690 weighs in at 74 pounds (66 pounds without the included battery) and has a standover height of 32″. Best for riders between 5’6″ and 6’4″, the XF690 Maxs’ saddle can be adjusted from 35.4″ to 41.7″ and the bike is 78.7″ long with a 49.6″ wheelbase. Smaller riders and those with limited mobility should check out the new Cyrusher Kommoda and Kuattro step-through models.

    Performance and Ride

    As you might imagine, the ride quality of this folding electric bike is very comfortable, thanks to the fat tires and full suspension setup. The XF690 Maxs delivers a stable, confidence-inspiring ride that’s fun on a wide variety of surfaces. Capable of performing well in sand, gravel, snow, and mud, the massive tires deliver excellent grip and make the XF690 Maxs easy to control, regardless of the terrain.

    This bike also packs an impressive amount of power, with ample speed, torque, and acceleration to handle just about anything you throw at it.

    Build Quality

    The build quality of Cyrusher’s bikes is always pretty good, especially considering the price point of these bikes. The XF690 Maxs arrives very well-packed from the factory, and setup is easy thanks to the included toolkit and detailed assembly instructions. Total setup time should be less than an hour for most riders.


    Cyrusher is well-known for its bold, eye-catching designs, and the XF690 Maxs comes in four head-turning colorways: Red, Gray, White, and Yellow. This is a big bike that is guaranteed to attract a lot of attention — there’s nothing discreet about the XF690 Maxs, with its oversized tires, full suspension, and good looking frame.

    Overall, we’d say that this bike gives off a premium vibe and looks as good, if not better, than a great deal of e-bikes costing twice as much. 

    Included Accessories & Optional Add-ons

    As Cyrusher always does, the XF690 Maxs includes a nice bundle of accessories. In the box, you’ll find an air pump, toolkit, 3Ah smart charger, and fenders. Additionally, Cyrusher sells a nice range of e-bike accessories you can order to customize your ride, including pannier bags, rearview mirrors, batteries, and more.

    Warranty & Customer Support

    The XF690 Maxs comes with a generous 2-year warranty, providing customers with an extended period of coverage that goes well beyond the typical 1-year warranty offered by most factory-direct e-bike companies. Additionally, Cyrusher offers a 14-day money-back return policy to ensure customers are satisfied with their order, and they don’t charge outrageous restocking fees like many brands.

    Cyrusher’s customer support is rated highly by customers, and we’ve found the company to be extremely responsive to inquiries. There are several ways to get in touch with the company, including live chat on its website (recommended), telephone, and via Cyrusher’s online contact form. Live chat offers the quickest response times (less than an hour, depending on the time of day), while support inquiries sent through Cyrusher’s online contact form typically receive a reply within a few hours…

    Final Thoughts

    A unique electric bicycle that offers riders a nice blend of portability and high-performance, the Cyrusher XF690 Maxs is a top pick for those who want the versatility and all-terrain capabilities of the Cyrusher XF800 and XF900 with the added convenience of a portable, folding frame. Unlike some folding e-bikes that cut corners when it comes to features, the XF690 Maxs pushes the limits of foldable bike design and brings riders a highly capable machine that sacrifices absolutely nothing.

    The overall riding experience of the XF690 Maxs is top-notch, and while it’s a bit heavy and even awkward to lift when folded, being able to collapse the bike on itself and throw it into the back of a small car is game-changing.

    Lastly, we love the fact that Cyrusher stands behind all of its fat tire mountain bike models with a rock-solid 2-year warranty and the company is quick to respond to customer inquiries whenever an issue arises.

    All in all, this is a great choice if you’re someone who needs this type of rugged, all-terrain performance in a highly portable package.
