My first was the Juggernaut Classic Duo. It was fantastic as well but I had decided I wanted full suspension as I mainly ride off road. We are lucky enough to have miles of off road trails to ride here. I typically try to ride 20 to 30 kms a day if I can. The new new Juggernaut Ultra FS Pro 3 has been nothing short of amazing. I have done a number of things to customize it specifically for me but it is awesome! M Mike Roberts Transformative. My face hurts. My face hurts. From smiling too much. What a blast it was to ride 16 miles and only using 15% battery suggesting I could get well over 50 miles with the 17AH battery - time will tell. When a hill approached, I kicked it up from Eco PAS 2 to 4 and breezed up the hill. A very steep dirt patch popped up and Sport mode PAS 3 made that lift easy. I did have some electrical issues, but they were resolved over the phone (a loose connector). So far, so good. This beast is strong. High quality. Glad I went with 3" tires - they breach any terrain and are just right for my needs. Now my two ebike buddies want to upgrade their hub bikes (Sondors and RAD) to Biktrix. Very happy with this bike. K KEITH PICKING Almost Perfect I purchased this bike to primarily use for scouting/hunting. I will also use it a bit recreationally. My particular bike was upgraded with the Wren hub and the Magura brakes,I’ve only put 20 miles on it so far and couldn’t be happier with my purchase. My only recommendation would be to see a stock forest green color option for us hunters, other than that the bike has been terrific so far. J Jeff Schreckler “I Found The Fountain Of Youth “ J.Schreck Mad History Adventures We do Extreme Adventures in the Southwest United States and I have been looking at various machines for exploration . After deciding on an e-bike the next task was picking a manufactuer . Communication and rugged quality was a major concern in the process. My choice ended when I called Biktrix . The staff guided me thru the process and it was painless . I look forward taking you along with me as we go explore the great desert wilderness Let Ride ! J.Schreck S Steven Conklin Excellent Purchase Experience From website, videos to customer service & purchase was awesome. Comparing the Biktrix Juggernaut FS Pro to other brands was easy to rule out Brands with worse websites & worse customer service. I purchased the bike on a Saturday online and was shipped on the following Tuesday & would have been delivered in 3 days from Saskatoon to NJ, but was delayed because of rain and flooding conditions in Memphis FedEx Freight delivered in 4 business days the Monday after. Finally got to put bike together 2 days later and happily riding the bike ever since. Have a single track ride planned today and expect to have a fun ride. Thanks Biktrix J Jim Roal Awesome off-road machine This is my second electric mountain bike. The first was a Rurui XT10 with hub drive and it was not well suited for off-road riding. This bike is! I like more serious off-road riding. I just completed my first 30 miles, mostly off-road. It included long, steep, loamy hills. My last ride was a 22 mile loop that has over 2,900 feet of ascent. Lower rider fatigue than other bikes as well. This off-road riding tends to eat batteries but I went about 30 miles on this charge and had 52% remaining without a range extender battery. Here is a YouTube video of parts of that 22 mile loop: https://youtu.be/NcHmBKLUrgU . K Kevin Pigeon Juggernaut Ultra Pro 3 I am so happy with the purchase of my Ultra FS Pro 3 . I still can’t believe how much floatation is created by the 4” tires on semi packed snow. The battery performance is amazing as well. I had been considering a Biktrix purchase for a long time. I am so happy I pulled the trigger , now I can’t wait for summer riding. Thanks Biktrix. 56 yr old KP from central B.C Canada M Michael Dascanio Great bike!! The bikers excellent to ride handles very well, but very heavy. It is very powerful and get you where you need to go or use her every day to go to work and back home.
