The mid-motor makes the Juggernaut Ultra Duo very versatile. Mid-drive motors are much more efficient than hub drives as they can use the bike's gears as transmission. Hills become something of a novelty with the new Biktrix Juggernaut Ultra Duo 1000W 48V Step-Over Fat Tire Mid-Drive electric bicycle.

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.
