Mudd and dirt all day

What a bike,I am very happy I found a option for a mid drive bike that didn't break the bank account.
It has been out on the muddy trails since I got it and it's a winner.power to spair and more distance then I have time to ride.
The duo battery system is a game changer.

Love my bike

I almost never peddled. I ran it all day and over 40 miles of scouting. I’m looking forward to doing it again.

Range

The Juggernaut Ultra FS PRO 3 MTB is my 2nd Biktrix bike with range extender,. 1st was a Juggernaut Classic Duo. It is a must have. Why? Best to have more than not enough volts. Prevents range anxiety when you are in the mountains.

Total Surprise

I added the 52V 21Ah Range Extender Kit for Duo Series bikes to my Biktrix Juggernaut Ultra Duo 4. Biktrix consulted me, and suggested I purchase it for my specific needs. I live in Southwestern PA where we have nothing but rolling hills, and most of them are hard to climb even with an e-Bike. I have four other e-Bikes (Hub motors), and the hills kill the batteries even on rides as short as 15-20 miles. Some 8 miles rides eat up 50% of my battery capacity.

My mid drive Biktrix Juggernaut Ultra Duo 4 with the Range Extender Kit will allow me to participate in rides all day. I took out my bike on a 12 mile break-in ride and I only used 6% of the battery. With 94% left, I felt confident in taking on any hilly terrain in our area thanks to the Extended Range kit. Thanks to Biktrix giving me sound advice and for designing and building a great bike for me.

The Range Extender Kit for the Duo Series bikes is a terrific value for the price, and it provides power for long all day adventures. I give it 5 stars!

Great for extended use of the throttle.

The throttle is such fun and with the power of this bike it’s a thrill to “open it up”. I find that the dual batteries allow me to use the throttle for as far and as fast as I want to go without worry about running out of battery power. Running the bike on peddle assist only, the range is remarkable. I have not yet tested the total range but the dual batteries definitely make a huge difference and the power level drops very slowly. Very happy I ordered the range extender kit.

So worth it

In the smallest size, you go from 52V 17ah to 52V 30ah, pretty much doubles your range. It's a no-brainer.
