ASSEMBLY
There is some assembly required upon receipt. Your bike will be completely assembled and tuned by Borealis, then partially disassembled for shipment. The remaining assembly will require installation of the rear derailleur, chain, fork, seat post, wheels, and handlebars. A multi-tool will be included with your order that has all tools necessary to assemble the bike, with the exception of a torque wrench. If you are not familiar with this level of assembly, we recommend having your local bike shop complete the assembly. Below is a video showing the remaining assembly once you receive the bike. Tires will be set up with tubes. Tubeless rim tape and valves are included on the side.

The bike is great . Fit to finish is impeccable. Comin from a mukluk this bike handles way better in deep snow. Better online manuals and vids for tech would be nice tho and are lacking.
I ordered a bike and it arrived with a scratch on the frame. I just asked customer service for some touch up paint but they told me to kick rocks because the scratch was my fault. How was it my fault? Is it my fault zip ties broke free of the cardboard and allowed parts to shift during shipping? I guess so. There were other issues that I won’t get into. Overall the bike is fantastic and a good value for quality. But if you have any issues with shipment damage or product quality then be careful, because that’s probably your fault because borealis quality control is incapable of mistakes. They do answer you promptly to let you know they are not responsible for their product quality so that’s reassuring. Bike: 4.5/5 Customer service: 1/5
Ive been riding deep snow for years in montana and I can tell this bike works well geometry wise for deep snow riding. I like the build and weight of the bike.. 10 lbs less than my other fat bike. The bike was a easy assembly for me a non pro mechanic in my garage.

This bike is so much fun! There are so many ways you can ride it, I can’t wait to try them all! The color looked even better in person(green). As soon as I got everything together it was so well tuned that the gears shifted flawlessly first try. it was a bit more work to put together than I anticipated but I think that’s mostly because I ordered the Manitou Fork and they installed the front brake stuff on the borealis fork that it also came with and the instruction video didn’t cover anything about installing the manitou fork and subsequently swapping the brakes over to it. I was able to get it done but it definitely added a good chunk of time to the job. like I said though once it was all together the bike performed amazingly and I can’t wait for the first snow! Also their shipping was super fast they’re super on top of getting it shipped out. I’ll be back to get a full wheelset for my summer wheels/tires in the spring! Thank you!
I recently bought a fully loaded Crestone and it is by far my favorite bike yet. I have rode it in many different conditions and it’s a blast to ride. Not the fastest bike I own but the most fun.
I have only ridden my Crestone a couple of times, to date. The rides have been on dirt. So far, I am very impressed with the bike. I am looking forward to riding on the snow. The quality of the bike is very apparent. I also have a Yampa, so I expected the bike to be top notch. Thank you for taking care of me!
Went to a local bike shop where I was able to test ride a fat bike (been on the fence about getting one). Salesman was super informative. Advised me to go to the website and build what I wanted. Easy process. Quick delivery. Nice looking bike. Smooth ride.
