Bafang BBSHD1000W mid-drive motor
The mid-motor makes the Juggernaut HD Duo very versatile. Mid-drive motors are much more efficient than hub drives as they can use the bike's gears as transmission. Climb the steepest hills. Conquer anything.

Dual integrated battery system
Range worries are a thing of the past with our dual battery system. One battery is embedded in the frame, while the other is mounted within the triangle of the frame. This positioning maintains stability, with no noticeable effect on your ride.

Thumb-throttle & control pad
Just a push of the thumb and this becomes a motorbike. The control pad allows you to turn the bike on/off and customize your riding experience. Just sit back and enjoy the ride.


LCD display
The LCD Display shows you all kinds of important information about your ride including speed, battery life, range, odometer, pedal assist level, and more.

Hydraulic disc brakes
Get strong & dependable stopping power from the hydraulic disc brakes, and extra traction from 4.8” Vee Tire Fat Tires. Choose 27.5×3 MTB wheels for less drag and a great commute on and off-road.

RST guide suspension fork
The RST Guide Suspension fork provides control, traction, and comfort, making for an even, smooth ride every time. It is just one of the many Juggernaut HD Duo Step-Over Fat Tire Mid-Drive features that add to the enjoyment of your eBike ride.

Integrated headlight
A bright LED will light your way when the sun goes down. It's powered by the bike's battery and can be turned on/off with a button on the handlebar control pad.
