I purchased a Gravity Monster Fat Bike in June 2019. Finally able to write about it now with 100+ miles rode. LOVE IT!... and Sooooooooo Happy that I didnt have to spend $1500 to get into a quality Fat Bike! I am 6ft. 3 #225lbs and the 20inch fits great!
Did have an OOB problem with a poorly machined Stem that would not tighten down. BUT... this just gave the support team at Bikesdirect the opportunity to SHINE! Larry took great care of me by exceeding my expectations! He swapped me some useable bikewear instead of a new stem as I was gonna be changing the bars and stem anyway... and that is my tip here!... Spend the $500, and plan to customize/upgrade various features to fit YOU!
I wanted a more upright body position so I spent like $50 on new stem, grips and bars with extender. I also took advice of previous posters and spent $15 on upgrade of the pedals that match my green color perfectly! Everything is working and riding great. I wont be doing anything serious on hills, but mainly gravel trails in local forests. I may upgrade to hyd. Brakes in the future, but standard mech brakes work ok for me now.
I DO RECOMMEND that you find a good bike mechanic to do assembly! Yes, a layperson can slap it together, but, a trained mechanic will be able to review all requirements for lube, alignments, fit, etc... and get your new ride to 100%... WORTH the extra $ that you saved!
