**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.

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

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.

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.
