Some of the features include a full suspension comprising of a RockShox Bluto front fork fat-tire, with a rear suspension featuring 100mm of travel and some preload adjust. There are Kenda Juggernaut fat tires measuring 26”x4” and have great nobby tread that can actually act as little dampeners, adding a bit of absorption, making them very comfortable for riding.
The comfort doesn't end there for this step through fat tire e-bike. The rims are pushed out to save weight and sport some super sturdy 13 gage spokes in the both the front and rear. To increase more comfort, there is a slopped top tube that makes the e-bike easily approachable to sit on the Velo plush saddle.
Choice of WHEELS MAKE ALL THE DIFFERENCE
There are Kenda Juggernaut fat tires measuring 26”x4” and have great nobby tread that can actually act as little dampeners, adding a bit of absorption, making them very comfortable for riding. Make your choice of either 26x4, 27.5x3, or 27.5x2.8 wheels.

PEDAL ASSIST AND THUMB THROTTLE GIVES YOU POWER ON DEMAND
This fat tire mountain e-bike offers five levels of Pedal Assist (PAS) mode to choose from. You can choose the level that's right for your type of riding. The Juggernaut Ultra FS comes with an incredible display on the handlebars. You can control this on the DPC-10 display that's included right on the handlebars.
As you pedal, the motor measures how often you're pedaling and helps you proportionally. You can boost motor performance by setting assist levels between 1 to 5 levels where level 1 gives you least assist but most range while level 5 gives you maximum assist and least range.
The high-contrast 500C display delivers all important information at a glance and can also be read in direct sunlight without difficulty. The aluminum handlebar display gives good feedback, is extremely robust and easy to use. This monitors your speed, battery life, trip meter, and choice of pedal assist level.The additional output can be individually controlled by five support levels. The user interface is clearly legible and intuitive to use. This display is protected against contact and ingress of water and dirt.
The Juggernaut Ultra FS can reach a top speed of 28mph of its Bafang Ultra geared mid-drive motor. This motor offers 1,000 watts of nominal power with up to 1,350 watts of peak power! But even more impressive is its 160 Nm of torque. Compared to other e-bikes that reach 50 to 90 Nm, the 160 Nm feels more exciting but might also put increased strain on the drivetrain and frame. This kind of power makes it easy to go up a hill.
The great thing about this specific motor is that it’s Bafang's newest version, which replaces some of the lower power designs that used nylon gears inside. Instead, this one uses all steel components which is considered an upgrade in internal parts should help the motor handle the extreme torque being produced and improve its overall longevity.
The torque sensor also does a great job of smoothly administering power equal to your output. When you push lightly on the pedals, you'll get a little bit of assist; and when you hammer down on them, the motor unleashes all its power.
Mechanically, you'll get a nice SRAM NX 11-42tooth (which is a great range for climbing) cassette, and a 42 tooth chain ring up front. When stopping the Juggernaut, there is a set of great 180mm hydraulic disc brakes in both the front and rear to help you come to a stop.
