ASSEMBLY
If you choose "No Assembly" your bike will require complete assembly with an exception of the wheels.
If you choose "Assembled by Borealis", 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.

Customer Reviews
I would highly recommend anybody looking for a Fat Bike, this is the bike! I chose to assemble it myself and the quality of this bike is outstanding. You cannot beat the value for what is included with a Borealis Fat Bike.
Feels so comfortable and very light! Love the gx groupset and the video to get it set up was helpful! Could have gone a little slower but I just paused when I needed! The color is actually so neat, went with the midnight blue. Looks black, dark blue, and purple in different lighting!
I custom built my Crestone and received it within about a week. IT IS AWESOME! I have a gravel bike and a hard tail 29er that I ride a lot. As much as I like those bikes, my Crestone is now by far my favorite! The single track is covered in leaves this time of year. I fly through the trail with confidence and no slippage. It is lightweight, has great components, and outstanding ergonomics. Stop looking. Buy one!
Can't wait for snow! For now I'm crushing front range singletrack and it really comes down to weight of the bike. It is 26lbs with 7lb YKY tires. 26lbs and 14lbs is just tires! They roll. They grip. The bike has a great geo and can climb. Out of the saddle I'm hammering climbs. Doesn't like to get airborne is the only thing I can think of, but hey - buy something else for that. I'm locked in now. Love this bike
I had never built a bike from just a bare frame before so I thought I'd give it a try. Thankfully you can learn anything from Youtube! Had one question for the guys at Borealis and they got right back to me with an answer. I was very happy with the customer service and the deal I got on the bike was awesome.
