Amazing for the price

This bike is an absolute boss. The tyres on this thing go over anything and the build is super solid. My only gripe would have to be that the brakes on it aren't the greatest in the world, but to be honest, for the price, it's nothing to stress about as the ones it comes with do the job well enough until you upgrade. 10/10 would recommend to a friend wanting a new mountain bike.

I had gotten this bike a couple days ago and it is the best bike I have ever rode. I have taken it through water, mud, sand, and it takes anything you can throw at it! First fat bike I have ever rode and it is so stable and does track standing heaps good! Overall review 8/10 :)
