Will not disappoint.

When I pulled the bike out of the box I thought what the hell did I buy!! What I bought was simply the best e-bike I've ever owned. She lives up to her name Beast in size but rides like a dream. I have not found a terrain this bike can not handle and fast for a bike bike this size. The mid drive motor has great power and performance. Everywhere I go people ask me about the bike and how it rides.

I had the beast for four months now with zero issues. I'm writing this review more to get Biktrix attention. It's currently not being sold by Biktrix, not sure why. It may not be there best selling bike due to its size and price, but from a marketing side the attention she draws, you can't put a price on. The quality of their products is refreshing and extent of product line is really unmatched. When my wife and I upgraded bikes she chose a newer bike company, Chinese made crap is all I can say(1 Up). I've spent hours working on her bike zero on the Beast. Come on Biktrix keep making the Beast2!!!!!

Do Not Hesitate!

Well, here’s the short version. Found it online, procrastinated for a bit. Reached out and inquired about getting a camouflage one, was told they only had a blue one left so decided not to purchase. Next morning, pulled the trigger on the blue (Juggernaut Ultra Beast). Went through all the layers of $5000.00 buyers remorse for two weeks waiting for it to arrive. Put it together late last night and took it for a 50km ride this morning…
All that elite marketing, all those sexy videos, all those 5 star reviews… they were all wrong…
This thing is a 10! This thing is beyond a Beast! This thing exceeded All my expectations!
To the entire team at Biktrix, thank you for all your support (especially Hasmik).
You guys knocked it outta the park with this one and I’m one happy Biktrix owner.

What a Beast!

After much research I decided on the Biktrix Ultra Beast 2. Delivery was quick (less then 1 week) and it arrived in perfect condition. Assembly was easy just follow the online directions or Youtube videos. I loved the fact that I could customize the bike right from the factory and even pick the colour! I emailed customer service with a few questions and their response was quick. Regarding the bike itself, I am a heavy guy and was looking for a strong bike that would pull my weight around with a sturdy frame and lots of power...this bike delivers!. With the dual battery no issue whatsoever with 'range anxiety'. Note that this bike IS a Beast, it is big and is a little narrow at the standover area if you are a big person, you will probably want a 31-32" inseam minimum. Overall very happy with Biktrix!

Great bike

I have taken this bike from city streets to high elevation mountain trails, and this bike does it all. So far I have no complaints, but I do have one suggestion. My suggestion would be a 220mm brake rotor option for those who are going to use this bike to max capacity in very steep terrain. The standard brakes really do work well but a set of 220s would be amazing. Thank you Biktrix for all the help you have been in getting me set up with this bike.

Nice bike

Happy so far, haven't got out for a long ride yet but plan yo soon. Only complaint is when ordering the bike the display came up as an upgrade so I added it. The bike already had one so it's not anupgrade. Bixtrik team should have noticed this and contacted me before shipping. Saving me 20 dollars to ship it back.

This bike is great. Have put 50 miles on it in the last 3 weeks, works flawlessly.

Back on the bike again

Bike rides great 👍 practicing for some down hill runs not bad for a 69 year old.


I'm a crusty old f*&%er livig in a rugged rural area and have a general distain for all things urban. Buying this bike wasn't about saving the world from petroleum products. I bought a demo model through Trapper Gords/North American Hunting Supplies so it had a few kilometers on it. First time owning an ebike so it took a bit to learn. I ride it almost daily in a hilly areas hitting the local logging roads for a couple hours and have never gone below 50% battery use. I use it for therapy for my hip osteoarthritis so I'm usually in 3 or 4 assist mode making the bike do a lot of the work. So far I've ridden about 200km so I think I can make a fair assessment. Loads of power to climb anything; and I weigh 230#. Rough terrain no problem. It seems very sturdy. I am used to riding dual sport motor cycles, and still do, but this is a lot of fun and capability in its own right AND I can ride the bike trails, bike lanes in town and piss off all the metro-sexual spandex prima donnas. I didn't intend to get one of those stupid looking bicycle helmets BUT after I got it up over 80 km /h on one the earlier rides I decided a decent good coverage helmet would be worth it especially when alone in rough terrain. I still don't think much of the people who wear the goofy mushroom top helmets.

I haven't been able to ride it or it take me for a spin. 2 foot of snow here in Wisconsin looking forward to the first chance.
