It's robust and capable without breaking the bank.

Disclaimer: this bike is not designed to use for competitive cycling or downhill mountain biking.

Throttle & control pad 

The Juggernaut Classic 8 comes with throttle-on-demand and cadence/PAS (Pedal Assist Sensor). 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 (or 1-9) levels where level 1 gives you least assist but most range while level 5 gives you maximum assist and least range.

    Three ways to ride the Biktrix Juggernaut Classic 8 Fat Tire Mid-Drive eBike

    • Pedal only (with no help from the motor)
    • Pedal Assist (with 9 levels of assist to choose from)
    • Throttle only (effortless like a motorcycle)

    The Biktrix Juggernaut Classic 8 Fat Tire Mid-Drive can be used as a normal bike where the rider provides all the power, or you can use just the throttle and let the bike do all of the work. There is also an in-between option, Pedal Assist, where the rider pedals and the motor provides a great boost at the same time. You can choose the level that is right for your type of riding. The Levels of Pedal Assist allow for increased ride efficiency, resulting in less strain on your knees while riding. It makes riding fun and effortless.
