**Please note that information regarding the expected range on a single stock battery 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.

Awesome Ebike

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. 👍

After a month now.

It's not easy to give a review with a brand-new bike with only just over 100 miles on it. Buying a new bike this time of year here in the NW of the United States we don't get to ride much being the weather sucks your soul more than you can ride. I find the quality and finish of the bike is very good. Very solid in every way. It's a bit slow in the first 2 PAS modes for my comfort. But understanding how much volts it uses, or let's say how much it doesn't use on the batteries is a plus. But a bit slow. If you put the bike in PAS 3 and above it does fine with keeping pace with others. I'm 5'8 tall. I got the smaller frame bike 17 I think is what it is. I have to raise the seat fairly high for my legs to be comfortable riding. So, it makes me feel like I'm kind of high over the bike. I'm sure over time that should calm down for me. I like the bright yellow color I choose for the frame. The black accent help with the overall look of the bike. The A bar was to flat for my liking. I gave it to a sibling to put on his bike. I bought the real Jones Bike H bar with a 2.5 lift. It feels a lot better on my shoulders. I'm getting use to the Wrem front forks and the Wren rear hub. I got help from Tej with programing my Ultra motor. I thank him very much for his help. The small change in programing I think will help the bike overall feel and keep me wanting to ride the bike more than the other 3 ebikes I own. I would like an invite to review the bike maybe this time next year. And see how many miles I get to put on it by then. Overall, I would recommend buying this bike if you want a large hunting frame bike that is very comfortable with full suspension and is powerful in higher PAS. But with city street manors. I went with the 26x4 inch fat tires. for riding in nearly all conditions. It will with ease.

I took my time, looking at, and tested so many EMTB’s. It was a very difficult decision. This machine is perfect for my needs. The ride off road is so smooth, and the ability to drop down in to some canyon with the power to pull you back out with absolutely no problem is amazing. Then there’s the distance, with the duo battery pack in sport mod you have miles. The 27.5x3+ tires on 2.5” wide rims are perfect for the weight and well needed, but they’re not to big for my weight 170lbs they’re perfect. I choose this bike because of its wheel base stance. And a few other things and it has absolutely exceeded my expectations. The whole process of ordering, delivery, and assembly was great. I have read the reviews on this product and I agree it is an amazing machine. It performs so well will pedaling. It invites you to pedal and pedal harder, but then there’s always that throttle for when you get tired and don’t want to pedal. Despite its weight with two batteries, 85lbs it is quite nimble, and with that weight you feel so planted and can climb out of anything. Can’t say enough about this product. Good work friendly people.

Wait to ride it

The bike passed my inspection. Now I must wait to ride it. Having kidney stone removed on 12/21/23. It is in the living room now. Cannot wait to ride it in the mountains. Nice to look at while recovering from surgery. I know it will be a big step up from the Juggernaut Classic Duo I own. The motor and suspension will make the difference. Again CANNOT WAIT TO RIDE IT!!!! It will be like riding my dirt bike. Pleased with it. GOOD BUY. More review after I heal up and rlde it. Sold my Juggernaut Classic Duo Mid drive to my friend who moved up from a Hemingway hub drive. Ready to rip up the trails.

Juggernaut FS Pro 3

This is my first Ebike. I wasn't sure what to expect. This bicycle far exceeds my expectations.
Assembly is easy for 1 person. Fit and Finish and Quality is awesome.
I rode it for the first time around my driveway and yard without the battery power turned on. I was very impressed
with how easy it was to peddle, it felt like a regular mountain bike.
Next I took it on a 7 mile ride with the battery power, I toggled through all the pedal assist levels and used the throttle only.
I couldn't stop saying to myself WOW, this bike is a blast to ride.
When I purchased this bike I selected the Sulfur Yellow powder coating (beautiful powder coating job, I love the color) I also opted for the upgraded Tektro Quad Piston brakes (fantastic brakes, they work very well)
The Armageddon Headlight (very bright) The Wren Star Ratchet Rear Hub and the Rear rack and fender set.
I am still fine tuning the suspension, seat and handle bar placement to make it all perfect for me.
I'm looking forward to many fun miles of riding, Thank You Biktrix.
