Crestone (Carbon) - Medium Green & Silver (ID 20634)
Chris
Couldn't Be Happier!

Wasn't sure what to expect with this being my first fat bike and all but damn I'm impressed. The Crestone feels much lighter than I thought, even with the bigger 120mm fork, and still very planted. The green paint is gorgeous, and the components are top notch. I shopped quite a few other fat bikes and none of them came close in terms of parts spec and craftsmanship for the money. Plus, they're based out of CO and it's always nice to support local! I had a couple last minute add-ons and Steve was quick to reply and get it taken care of before I arrived for pick up. I normally ride a size large gravel bike but I sized down to a medium and it worked perfectly. Can't wait to put many more miles on this thing!

HED Aluminum Wheelset 26" or 27.5"
Thomas Huysman
Great Wheel set

This is my second pair of HED aluminum 26. I have put a lot of trouble free miles on my first set and plan on many more. Thanks to the Borealis team for unparalleled service!!

Back on the trails

The Keystone is my first e-bike having been a fat tire mtb enthusiast this was a no brainer, it is the most fun I’ve had on a fat tire bike. Love it !! thanks Borealis.

Crestone (Carbon) - NEW Frame Only Size XL Midnight Blue & Bronze
David Johnston
Beautiful frame and paint

Bought this xl frame to replace my 5 year old crestone. There was nothing wrong with my old one (had 13,000 + miles on it) but the blowout price on the xl was so good i had to buy it. paint is incredible.
