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.
Customer Reviews
The entire process was smooth, and the special discount to Military & Police is greatly appreciated. I have been a mountain bike rider for years, and taught biking for the police, and this is my first fat-tire bike. Top-notch product and beautiful carbon work. I can't wait to get it out on the sand and snow!
I have been able to test the bike on various summer rocky and sandy Colorado conditions. My bike handling needs to improve to catch up with the bikes abilities. Love it and can’t wait for other seasonal conditions!
Very versatile all season tested. Select Carbon
Crestone SRAM GX 12 complete bike

This is my first mountain bike/fat tire bike and it is PERFECT for my beginner skill level in our western Massachusetts woods. I LOVE IT and I'm looking forward to being able to ride year-round.
Putting it together was easy enough with the video, though I do wish the video was slowed down just a smidgen and included more closeups--we had to do a fair amount of pausing/zooming in. I also wish that somewhere it had said that the bike doesn't come with pedals (likely understood for folks you have bought bikes like this before, but not for a noob like me.)
Bought this for my daughter so she can ride with me in the winter. Great bike!! Easy to put together and love the paint color!
