**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.

What a wonderful experience this was and will continue to be

First let’s start with the fact that we (my wife and I)went to the local Kelowna BC showroom to see and test drive a few different models. Dillon Terry, the showroom manager, was really friendly and knowledgeable. He was patient and so respectful and he took the time to explain the differences between the models and helped us test drive 7 different models. We are not new to e-bikes, having owned each two different make and models before. After searching the web and comparing models, we decided that buying local and from a Canadian manufacturer made best sense. I selected the Juggernaut FS Step-Thru for the full suspension and torque of the motor. The ride is smooth and the motor makes the steepest hill of the region feel like you are on a flat road. Service is excellent, friendly and if you go during the week you will also be met by a furry four legged friend. I recommend shopping there. They have so many models and variation on models that you should find the best fit for you. It’s also nice to be able to personalize the colour of your bike if that is something you wish for.

Absolutely perfect, power is awesome in any mode brakes are amazing love the smaller tires instead of the 4 inch Clayton was a pleasure to deal with, bent over backwards to put the deal together

Adjust power provided by modes

I need to be able to adjust the power provided by each individual mode. The throttle reveals that there is a lot of power provided by the motor, but the six modes are underpowered. This should be a way to increase the amount of power provided by each mode. And I’m not talking about How you can decide how much power is provided each mode, you know the 25 %, 50 %, 75%, 100%. I’m talking about when you’re at 100% of let’s say the mode Boost, that the motor provides much more power. And I’m talking about the power that is revealed with the throttle. The bike has huge power, but it’s not delivered fully in the modes. Can this be fixed?

Great bike!

Received the FS Step thru fat tire bike and assembled it a month or so ago and have ridden it a few times. Was worried about the display as the handle bar was protruding from the box a little bit but everything worked as it should. All the parts look good and seem really solid. Assembly was a smooth process...bike is heavy so smaller individuals might need a 2nd pair of hands to take it out of the box and to hold the forks up to get the front tire on. Instructions were good, would be nice to have torque values for all the bolts and nuts. Once everything was put together (took a couple hours), the bike rides very smooth, and the default battery lasts way longer than I thought. A long bike ride in the 'sport' setting for me only got the battery to 75% so lots of rides per charge..battery is easy to take off and charge. There aren't many hills around here so battery drain would be more if you're in a hilly area. Chain, sprocket, gear changes, etc were all great right off the bat. Glad I went with the large size frame (6' 1", 32" inseam). Not a complaint, just a heads up for those coming from a basic mountain bike, this bike is heavier than I thought it would be and the fat tires are huge compared to a basic mountain tire. Next purchase would include the regular mountain tires but I'll have to try this beast out in the snow this year to see how the fat tires do...I wanted a bike to ride around the farm all year if possible. Overall, very happy with the purchase and the bike so far!

What to do next

Really like the bike, has a fantastic ride didn’t have to make any adjustments. Spent a lot of time on both front and rear fender noises. Rear one was loose from the start. Now I realize I don’t have 11th gear and have delayed shifting when shifting up. The pannier bag doesn’t fit the rack properly. All in all, I still like the bike, and hope to resolve this.

YOU WON'T BE DISAPPOINTED

Been on my New FS Step-Thru for over week now. This RidgeRunner is an allrounder. From across town, the city trails, to an adventure up a mountain, such FUN! The Power of the Bafang M620 motor, the 100km distance of the 52V 1300Wh battery, fast cruising speeds, and the comfort of the Ride. YOU'L LOVE IT... and won't be disappointed.

I STRONGLY RECOMMEND the Biktrix FS ST eBike,

My do it all Juggernaut.

I cannot say enough about my Juggernaut, so I'm gonna try my best to keep this short & truthful as possible. This was not my first ebike. My first ebike was manufactured by a major brand and was more expensive than my Biktrix purchase. In short, the Biktrix bike blows my previous bike ( hint: begins with a T) right outta the water. There is simply no comparison. I absolutely love my bike! Biktrix is also not cheap to purchase but the craftsmanship & quality are top tier. You guys build the Bugatti of ebikes as far as I am concerned. I waited for this bike from time of order to in my garage of almost half a year & if I could do it all again I'd do the same thing because of the end result. Lastly, even more than my FS, what impressed me most was your customer service. I communicated by phone with Clayton (ext.108) throughout this process and he was genuine & professional to deal with. He is the real deal and I know he really cared about my 100% satisfaction. So my hats off to Mr. Thomas and his team at Biktrix! Keep doing exactly what your doing because actions always speak louder than words. Sincerely, Dave

Love my Juggernaut FS Step-Thru MTB

The bike arrived within 4 days of my order and was protected in a great reusable shipping box. This is my 6th ebike over 7 years and I can do my own periodic maintenance. My first ride was perfect. The setup was perfect. Shifting was soooo smooth and quiet. I had a 1000 watt Bafang on my older fat tire so I was familiar with what to expect. The acceleration on the Juggernaut literally threw me back on my seat…. far faster than my previous fat tire. I’m impressed with the quality that was put into this bike.
