Fits and looks nice.
The customer service closed the deal for me. They answered all my questions in detail and responded to emails within 24 hours. Bike packaging and assembly were pain free. Make sure you follow the assembly video. I am 100% satisfied which is rare since I’ve owned and rode many bikes over the years Thank you.

Great bike
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.

Incredible value for the money
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!
