**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.

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

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!

Nice bike had to take it to a bike shop after first outing. The bike gear cable came loose and I couldn’t get it field adjusted. I had to rig it to get the 3 miles back to my vehicle.

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,

First Impression of Juggernaut FS Step-Thru Fat

I am very impressed with the build quality of this E Bike, charging the battery is 3X shorter than my wife's current E-Bike "amazing"; the power of this unit is solid and going up a 65 Degree incline was a breeze, First ride was 22 mile and battery was at 83% when we finished; cannot wait to max the battery life on a 50 mile round trip ride. I would recommend this E-Bike for any type of rider
