Juggernaut Ultra FS

This bike is awesome! The whole thing seems to be made very well and with good quality parts. I bought this bike mainly for the power of the motor, because I am towing my special needs son in a trailer with a total weight of about 150lbs. This bike is amazing! I have gone on a few rides now and have gone up steep, long hills with no problem whatsoever! It's like riding on flat ground even on the biggest hills, and doesn't max out the power output. The battery seems to last a long time as well. After about a 30min ride on PAS 3 and going up about 8 decent sized hills while towing my son, the battery only dropped by 2%. The suspension feels like you're gliding on air, which I guess you sort of are seeing as the front and rear both use air-shocks...(You will need a special shock pump to adjust these...a standard bicycle pump can't achieve the high pressure needed)

I am 6' tall and bought a 19" frame which seems to be the right size. It's a bit confusing because the 19" frame says it's a Large frame on the website, but the frame says Medium when you actually get the bike. If you're unsure of what frame size to get I would suggest going with the bigger of whatever 2 options you are looking at, because the frames seem to fit a little bit small. (This is the opposite of what their website recommends, but I find that the seat has to be quite high for me and I can still put my feet comfortably on the ground)

There are only a couple of downsides that I can see so far but they are minor things. First, the motor is a little bit noisy, but that's to be expected from this amount of power output. The other thing is that there is no indicator on the shifter of which gear you're in, so you need to keep track of that yourself. Being a mid drive bike, make sure you are using your gears correctly and starting in an easy gear so that you don't put excessive strain on the motor.

I would highly recommend this bike!
Oh, and a shout out to Henry and Daniel...both of whom helped me out with the sale.

The only complaint I have is the weight of the bike. It is too heavy for me to lift onto a bike rack by myself. Performance and range however is very good

I absolutely love this bike. It's my first electric one and I have zero regrets. I've been out on it practically ever day!

As it is winter here in British Columbia I have only put on about 20 km! So far very impressed with the power and very smooth suspension. Looking forward to hitting the trails soon

I have been enjoying the original Juggernaut Ultra FS since early 2018,
now with over 17,000 miles.
Took advantage of a great offer for the Juggernaut Ultra FS Pro 3 Mullet and received it this January ’25. With the additional range extending battery. I hope to ride longer and explore our back country here in California.

Thanks to the Biktrix team for making me happy for many more miles to come!

Fs pro 3 ultra. Thumb throttle didnt work called henry ext 122 left him a message. Was ordered with half twist throttle wasnt on the bike then biktrix sent me just the throttle without the half grip hopefully biktrix sends me a new thumb throttle and the proper grip for twist throttle when i want to change it over

Bike is heavy and clumsy. Very powerful, but steers like a tractor trailer and is heavy like my dirt bike. Trying to return the bike costs $550 return fee, PLUS a 15% to 50% restocking fee, which they decide when they receive the return. This policy was of course nowhere to be seen when ordering. Utter nonsense. I hate the company more than the bike.

I’m very please with the choice I made and more then happy to recommand your compagny

This Full Suspension mid-drive MTB Ebike is incredible. Great ride with lots of torque to climb hills. The hydraulic breaks are solid. They can stop the bike quickly if needed. I have had the bike for a couple of weeks and I am thoroughly impressed. Great purchase. Their sales and customer service support is very good. 👍
