Quietkat Ridgerunner Fat Tire Electric Bike

Sale price$6,599.00


Some of the most rugged terrain on the planet is found in the Rocky Mountains. The beauty of this place is only matched by the danger and exposure faced while enjoying the grand peaks and valleys. To conquer this terrain you need the ultimate machine.


The 1000w BAFANG ULTRA MID-DRIVE MOTOR is a true marvel of engineering, over 1600w of peak power and 160nm of torque allow you to accelerate up steep inclines like never before. We chose BAFANG because they've been the industry leader in e-bike motor innovation and build the highest quality, longest-lasting, and most powerful motors in the business.


The all-new Fat Tire RidgeRunner is a full suspension electric mountain bike geared towards exploring the backcountry like never before. The Fire-Link suspension system is a true four-bar linkage, providing the ultimate traction and capability while 4 piston hydraulic disc brakes allow you to keep control.


Built on a 26″x4.8″ Fat-Tire platform, the RidgeRunner is designed for a wide variety of technical, off-road terrain including soft sand and snow, as well as hardpack trails and rocks.


The Fat Tire RidgeRunner is available as a 1000W unclassified e-bike and can be programmed down to 750W for Class 1 and Class 2 operations.

When we started designing the 2021 RidgeRunner, we wanted to make the most capable electric mountain bike ever made, we feel we've succeeded with the all-new RidgeRunner. 




The 2021 RidgeRunner features 120 millimeters of rear suspension travel and 150 millimeters of suspension travel upfront. Paired with the 4.8-inch fat tire, you can literally go anywhere and bring everything along with you. 

The RidgeRunner is available with 750 or 1000 watt motor options and comes in 17 and 19-inch sizes. New for 2021, the RidgeRunner is available in Charcoal or Veil Camo. 


Upfront, you'll find 150 millimeters of suspension travel out of the fork. Paired with four-piston hydraulic disc brakes and 203-millimeter rotors. The RidgeRunner features our fire-linked suspension system, which is a modified four-bar providing ultimate traction on any terrain. 


The RidgeRunner is built with the BAFANG's M 620 ultra drive motor with a torque sensor in either 750-watt or 1000-watt options. Pair that with our one by nine drive train featuring a wide range of gears to ascend even the steepest slopes. The RidgeRunner is available with a number of QuietKat accessories, including our trailers, lights, racks, and bags. The QuietKat RidgeRunner is compatible with our flex fenders that can be mounted in the rear as you see it here. It can also be mounted on the front tire.
