Thx

Have had my Ulta Duo 4 for a couple weeks now and I love it! Lots of power and comfortable to ride, it went together well out of the box with just a few adjustments. I'm looking forward to putting many miles on this beast.

easy to assemble, great ride

This is my "second" Ultra Duo 4. I wanted a Canadian assembled, mid-drive, fat tire, step thru e-bike with dual batteries. Not only is it the only one in the market place it is backed by the best company. Every communication with Biktrix over the past 5 years has been stellar.
So I now have a green one and a red one in the garage waiting patiently for spring. Okay not so Patiently!
I have now ridden over 11,000 kilometers on my first Ultra Duo 2 and the first
Ultra Duo 4. With the two batteries there is no battery fatigue syndrome. The Thudbuster ST seat post with the 4 inch fat tires provides a very smooth ride. I can only say that when deciding on my "third" Biktrix the Ultra Duo 4 is an easier steering bike than the Ultra Duo 2. There is no under-steer. The only non Biktrix option that I added to the new bike was an adjustable handle bar riser that is user friendly and on long trips you can lift a lever and adjust your handle bars without rummaging through your tool box and wasting time. This a very convenient option that allows you to adjust your sitting position and arm position quickly.
This new Ultra Duo 4 is my 80th. birthday present and my one wish is that when we take self directed e-bike trips in Europe that I could take my own bike with me. It is cost prohibitive so we get to compare other e-bike, mid drives with Biktrix and they all come up short.
We are all fortunate that Bitrix is in Canada.
Treat yourself and ride a Biktrix.

Juggernaut Ultra Duo 4 Step-Thru | 52V

Great bike, best i ever ridden
Feels strong and solid,very powerfull i was towing another bike up the hill at 30+ km/h without much effort. Smooth and responsive. Very easy to assemble.
Great job biktrix !

Everthing about the bike is well made. My only complaint is that i dont know whether or not there is enough grease in the motor.. i worry that the motor whines a little bit too loud.

I just got the bike put together a couple of days ago, but the weather has been terrible here lately, so I haven’t been able to ride it yet. The bike looks great and seems to be functioning properly. I can’t wait to ride it.

Got the new juggernaut duo, after ther crazy fedex issues. Bike came perfect packaged very very. Easy to put together and ready to ride in about half an hour.
Love the step thur model compared to my step over.
