[Select] Range Extender Kit for Duo Series

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.

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

Works great added more mile time for my particular riding.

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.

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!

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.

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

The bike is a bit heavy but when riding you don’t feel it. It rides very nice. It pics up pretty quick. The times I have had it out nothing but Fun!!
