For it's size, and especially, it's weight, it could have, should have, produced much more than 15Ah. Should be at least 35Ah, then maybe worth the $900. high price.
I’ve waited several weeks to do this review because I wanted to give it a good shakedown.
I have a number of bikes both e-bikes and analog but wanted one that I could ride more easily in winter conditions as well as in sand and other looser surfaces. This Juggernaut Ultra Duo 4 ticked all the boxes without breaking the bank.
The bike was delivered to my home via courier and assembly took less than an hour and the required tools were provided. After a full charge of the battery the bike was ready to go.
I like the fact that it is a mid drive which really helps on hills because both the motor and my own pedal input can take advantage of the gearing. I also really like the fact that I can add a second battery to double my range if I want or need to.
With the fat tires smoothing out the terrain, the bike is very comfortable to ride. The pedal assist and throttle are responsive.
The bike is heavy though so getting it on and off a rack to transport it, is a challenge.
I had two problems with the bike when I first received it, but customer service were very responsive and both of the problems were resolved, no questions asked. One issue required replacing a brake set and they shipped me a complete new set, front and rear, and offered to reimburse me $60 for my local bike shop to do the work.
The other issue was related to the torque sensor sensitivity and was resolved via a remote programming change through my computer using a Bafang programming cable which they shipped to me.
All in all, an excellent bike and I’m very happy with its performance and the customer support that I’ve received.
Merci pour la livraison rapide de nos deux nouveaux vélos Stunner Lite 3 ST.
L'emballage des vélos est très bien fait et les vélos sont dans un état parfait. Les couleurs sont très belles.
Merci aussi pour le support à bagage avant. Cependant, il a fallu que je le retire après l'avoir installé puisque les câbles empêchaient le guidon de tourner complètement vers la gauche. Petit travail des 20 minutes supplémentaires pour chacun des vélos.
Bien sûr avec l'hiver qui n'est pas terminé, nous n'avons pas pu les utiliser sauf pour un petit tour dans la rue de 2 minutes. À voir au printemps.
Pour ce qui est du manuel d'utilisation de l'écran digital, j'ai dû faire des recherches sur votre site Internet pour enfin trouver plus de 35 modèles sans image pour bien le reconnaitre. Il a fallu que je dévisse complètement l'afficheur pour enfin lire le no de modèle en dessous. Vous pourriez inclure le manuel en pdf correspondant au vélo livré avec la facture.
J'ai traduit le livret du modèle 500S-U en français, avec l’aide de ChatGPT, pour mieux comprendre les ajustements.
Si vous le désirez, juste à me le demander (500S-U Manuel Affichage Biktrix ST 3.pdf) et je pourrai vous l'envoyer.
This battery and addition for the rear rack to mount it are a great addition to a spirited, well made ebike. Great to not have range anxiety now. Everything was easy to install, and fit together well. The RogueHawk2 is my 10th ebike since 2019 and not only the best bike yet but, checks all the boxes for anything I could want in an ebike. The RogueHawk2 Can easily be configured to give a confidence inspiring ride to novice and seasoned riders alike. Highly recommended.
Bought this bike to replace a Specialized a Turbo Comp..Great bike!
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.
these guys are great even get service on sunday nights lol
easy to assemble, great ride
This bike is awesome! I love how it can do trails, but also roads.
The only thing I would say is that sometimes it doesn’t like the lower gears and the acceleration will go off and I have to stop the bike and go again. That for some reason resets it and it’s find.
Overall though I am very happy!
First ever e-bike, glad I picked this one, so far everything is good. Smooth with lots of power, and battery life beyond my needs. Yellow looks pretty cool as well.
I haven't ridden the Swift CVT 2 much yet as the weather in the PNW has been cold and wet. My first impressions so far however are that the bike is well built with quality parts. It was shipped in a box and was very well protected inside. My only initial issue is that the torque sensor does require more torque to get the pedal assist to kick in. You actually feel/hear a bit of a click when the pressure on the pedals is enough to engage the motor. I wish there was a way for the user to adjust the torque needed to a lower level. If it would engage the motor earlier and at a lower power level, it would make a more smooth transition.
The CVT twist grip will also take some getting used to, as opposed to actually shifting gears. I love the belt drive over a chain.
I can't wait to get out and ride more!
Only had a few rides before the snow arrived. But really enjoyed the rides we got. Can’t wait till spring
I like the bags, but the 4 hooks on the inside of the bag don't fit the bike, I had to grind them off, a little Micky Mouse ! You need to fix that !
Wow this new battery is the schizzz
I know Snooop would approve as well
Back on two wheels and loving it
Thanks Biktrix
I’m three deep now jaugernaut FS and two Swift bikes !!
Holiday Gift
This tire come to USA with 25% tax, it is imposible to return because of high delivery fee
I am very disappointed with the way this order was handled.
I placed my order on December 27, at a time when Biktrix was still actively accepting purchases and presenting delivery timelines (7-10 days or so) as if they were reliable.
Only afterward was I informed about “factory closures” and delays which end up with a delivery on 26th Jan).
If delays were inevitable, then the delivery schedule should have been accurate from the start. Accepting orders while knowing the timelines are unrealistic is misleading to say the least.
Customers should not have to absorb poor planning under the blanket excuse of “post-pandemic issues" so i hqve been served as an explanation. Transparency matters in order to maintain business credibility and custoners services oriented and, especially for high-value purchases.
I expected clearer communication and more professional logistics management. I am greatly disappointed.
The overall quality of the bike suits me and meet my requirements though.
We have not have a chance to ride them yet as it is still winter here. I am having issues with turning on my display.
