**Please note that information regarding the expected range on a single charge on one of our e-bikes is an estimate, not a guarantee. There are many factors that contribute to the actual, real-world range for an e-bike battery such as the age of the battery, temperature, level of assist, speed, payload, and terrain. Depending on these various conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range.

Juggernaut ultra 2

Only had the bike out a couple of times. The weather has not been great here in April. Loving the bike so far. Time will tell. climbing hills and Head winds are a thing of the past. Looking forward to Summer.

Ride on

Got my bike less than 10 days after ordering and had all my questions answered along the way. Bike showed up as ordered and operated great right out of the box. I opted for the 11 speed and Wren hub. I’m looking forward to riding into work this summer. Overall, this bike is a blast to drive and is very well put together. Cheers !

Ultra Duo is a great fit for me

I spent hours on the Biktrix website comparing the various models and alternative features of the models. I decided the Ultra Duo was the most affordable and best fit for me. Since it arrived I have ridden it on gravel and pavement and dirt pathways. It handles well in all environments. I really enjoy the ride. While I still have much to learn about the features I know that I will get many happy miles out of this beauty. Also glad that I sprung for the Biktrix A-bar and the comfort grips.

Test ride only still at the bike shop.

The bike engineer says there's a defect and the Front fort and it has to be replaced making a loud noise. Waiting Your service department to reply to my bike mechanic. Not happy

Juggernaut! Without discussion.

I love it. This is my second E-Bike. First one is ok with few flaws. The Juggernaut with cassette and brakes upgrades is just perfect for me. I'm 6-2, 260 pounds and carry a lot of luggages with no effect on the performances. Riding my biktrix daily remains a pure pleasure.

What a dream to ride, it takes me back to when I thought I could go anywhere!

I really like my new Ultra Duo step-over. I am learning all about it. We need a dealer in Calgary. I believe the drive train needs some tuning as sometimes it shifts on it’s own.

Wonderfully capable EBike

II am 66 years old. have had my UD3 for about 4 months now. In that short timeframe I have logged over 2500 miles on it. Riding It is so much fun that hasn't been hard to do. It is in charge and it gets noticed. I ride it on roads, trails and in the woods. This bike cannot be stopped, I and have yet to see another bike that can outperform it at any price. It will climb just about anything, as long as you can stay in the saddle! It is a big powerful bike that might take a little getting used to at first due to the sheer size and weight of it. But it is precisely the size, weight and power of this bike that make it such so exceptional and comfortable. You will ride with complete confidence in your newfound "partner" and it will not let you down. Get the extra battery (you will not want to get off this bike) and the Magura brake upgrade and it is even better! It has opened up a whole new world, conquering terrain a lesser bike could not dream of tackling It is worth every cent I paid for it. It is superb. As for the people who work for Biktrix, they are second to none.

Jaggernaut Ultra Duo 2 Step Over

I went on vacation and got home to my new BikTrix Jaggernaut Ultra Duo 2 Step-Over Camo Bike. Was easy to get together and get started. I charged up the battery and put 20 miles on it my first day. This bike is really fun! I am 40 years old but honestly feel like a kid again riding this bike. The customer service was great! They helped me find what would work for me and answered all my question promptly throughout the process. This Bike is awesome!!

Juggernaut Ultra Duo 3

They say to save the box just in case. Well guess what, they never getting this thing back. It's mine now! I did a good amount of research beforehand and although I was a little skeptical because of the price and a couple of bad facebook reviews, I could not be happier with my decision to go with Biktrix. Customer service sent out a replacement front brake rotor that was damaged during shipping and I had it in my hands two days later. Canada to Louisiana in just two days! The bike rides like the wind and everything about it is high quality. I can comfortably recommend this bike and company with confidence. And yes, I'll be discarding the box.
