    • A Big and Tall guys’s bike.
I purchased this bike because I have always wanted a nicer than Walmart bike. I think I read every review on here before I purchased it. What I can tell you is that this bike is perfect for me. I am 6’3” and weight 310lbs. This bike is almost Too big for me in a tall sense. Which I love this about it. I feel so sturdy and comfortable. Shipping was terrible however. Yes the package arrived with minor damage to the box and few scuffs on the paint. But that doesn’t bother me as bad as telling me it was prime and would be delivered in 2 days when it actually sat somewhere for 2 days without any honesty in the tracking only that it was sorry it was late. It came the 4th day in a strange box truck and was left in the weather in the driveway. But, this thing is a beast and made to take the elements. All of that is over and I am having fun and getting exercise. People definitely will walk over to me to ask about it because it is so huge. ... show more

    • Good fat bike but not perfect.
Color: Black Size: Medium Frame
Very nice fat bike for the money. The 4.8 inch tires go through loose sand better than even my 4.0 fat bike. One issue is the sizing of the frame. The medium is rated for 5'7" to 5'10" but the design of the fork and frame makes the top tube angle much too high even in a medium frame so that this bike a little dangerous if I have to get off quickly--it will hurt. Interesting because my Minnesota Fat 3.0 has the same length of seat post tube but does not angle up so high yet can fit 4.7 inch tires--that's why the 4 star rather than 5 star. I did replace the stem and handlebar to an adjustable stem so that I was not leaning over as much. I also replaced the suppository seat with a cruiser style seat for now--the seats that come with bikes now should be illegal :) Although they are considered more professional, I will also be replacing the crank system with a square taper version later to be able to put a dual crank on the front with a 22t and a 32t sprocket system for better uphill climbing like my Minnesota Fat 3.0 currently has. ... show more

    • Exceptional Fat Bike that doesn’t break the bank
Review Image by Stormtrooper1138
Review Image by Stormtrooper1138
I wanted to get back to riding a bicycle mostly for exercise reasons, and I want to note that since my late teens I hadn’t used one and I am 52 now, so you do the math… :) so I wanted to get a bike that let me relieve the excitement of those days. When I asked my friends who are very active in the MTB scene about getting a Mongoose, they told me that the brand wasn’t what it used to be when we were growing up. “The brand got sold to Team Pacific and they have dropped the ball in quality standards. You are better off with a Fuji or a Trek or a {insert expensive brand here}. So I went on to do some research and and none of the bikes they recommended were in my budget. Trek’s were minimum in the $1500 range and up. Other brands the same, so I went back to the brand I knew and did some research to see what exactly was so bad about it. I could t find anything on the reviews I saw that was a glaring red flag and the price for this bike was reasonable for the components it brought. Oh and why the fat tire? I like to try new things, and I had heard a lot about what a comfortable ride it was. The bike comes disassembled in a giant 4’ tall by 6’ long box. The guide is fairly well described and in 20 minutes or so you can have the bike assembled. The tires came prefilled with the right amount of air. When I took the frame out it was super light given the frame is Aluminum more on this in a bit. I am 6’4” and I had to lower the seating and raise the handle bar of the bike to begin with. I don’t think I had driven such a tall bike before. But as far as the ride it’s really good at least for non pro me, the gears help with the rough terrain and because the bike frame is so light the fat tires compensate maneuvering through rough terrain. My backyard is almost like a box park, I have hills and slopes and flat areas and while I’m still working on the hills, I can pretty much run this over grass and mud without breaking a sweat. The bike has disc breaks and you get amazing control when on surfaces where you wouldn’t be able to slow down otherwise. The only original component I changed was the bike’s seat because I don’t have much of a butt and that thing was brutal. I got a cloud nine seat and I’m good. After riding this bike for a couple of weeks I have come to understand why you would want to spend some extra money and get a decent bike. I could have gotten a $300 bike with crappy components and super heavy frame, and then in the upcoming months spend more money in replacement parts that would anyways raise the investment higher. But I went with this one because for $1000 it gave me all I wanted and then some on a bike. I have to admit that I’m restricting myself to my backyard for now, I feel regardless the bike I had gotten the balance aspect is something I need to get worked on, so I’m not falling on the neighbors thorn uh thing on the side fence lol but whatever, I’m doing more exercise I have done I. Years voluntarily and I’m having a blast. ... show more

    • Seriously good fatbike value
Color: Black Size: Medium Frame
Review Image by Keru
This is a great bike! I got into the Mongoose fat bikes starting with the Beast and Dolomite and have put together at least a dozen. Then got a Vinson which is a step up with alloy frame/wheels and 3-8 drivetrain, and now I have this Argus that is even finer! This one is now more than just a great value in a budget fatbike, it is a really solidly assembled serious trail bike. 4.9 tires on the one I got (not 4.8) and most all of the adjustments were spot on out of the box. The shifting is perfect and crisp, chainline handles the 1-10 gearing without complaint. I had to adjust the front brake mounting a bit and loosen the front axle bearing load a bit too but everything else is impressive. I'm used to having to adjust and tighten everything with a bike-in-a-box purchase. I love the way this one handles sandy trails, tracks right through the stuff, and it climbs rocky stuff great as well with low air pressure of 10psi or so. I love it! ... show more
