**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.

Nice ebike

My only disappointment at this time is the headlight. Biktrix should offer some options between the 100 lumen basic light and the 2000 lumen Armageddon. 100 lumen is only good to be seen. In order to see the road without blinding other drivers, an 800 lumen would be a good compromise and more affordable than the Armageddon.

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.

Juggernaut ultra dual 2 with 17” frame

Bike came well packed. Information needed to assemble was available on line although can be confusing to find. Slight variances in forks displayed in videos versus my build needed closer scrutiny as documentation doesn’t inform you ahead of time which specific fork or other components deviate from videos. Nothing major and the assembly was smooth. As for the bike it is everything I hoped it would be. It does take a little getting used to as to when to shift or when to use the throttle. Of the 9 gear ratios the first 6 are quickly run through whereas the top 3 are the usual cruise gears you’ll run on. I find that on trails rather than constant shifting I can feather the throttle to assist a little more going uphill while in mid gear rather than shifting all the way down to first. May not be totally right thing to do but it works for me and my weak hamstring. I need to boost the front forks as they are soft for my weight but no problem. I am so happy I got the smaller frame but quickly realized I needed to raise the seat for proper leg extension. More engine noise than expected but less road noise with the 3, 1/2” ATB tires. As most do I tried it full throttle and was amazed at what it could do. Have to say it’s everything I hoped for and I hope to put a lot of mileage on it this summer. PS Consider the brake upgrade as I did and you’ll be happy with your decision.

Good - in every way

Great web page and easy ordering. Juggernaut Ultra Duo arrived in record time and was easy to assemble with YouTube videos.
Bike has been fun to ride; lots of power, smooth ride on gravel roads and trails (bought as an “off-road” bike) with no complaints. Great experience with Biktrix.
