“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

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

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 .

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
