Description
Biktrix 2024 Juggernaut CLASSIC DUO Step-Thru 750W Mid-Drive Electric Bike
The Juggernaut Classic Duo Step-Thru is back by popular demand. This time round, there are many improvements such as an integrated battery and motor, suspension fork and much more.
Our Juggernaut was the first electric fat bike that has a custom Bafang BBS02B motor built into the frame – more ground clearance than any other BBS powered bikes.
Both the Juggernaut Classic variants come 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 levels where level 1 gives you least assist but most range while level 5 gives you maximum assist and least range.
The mid-motor makes this e-bike versatile. The Juggernaut Classic Duo features optional dual batteries that allow you to go as far as you desire – and never worry about range.
