Such a great bike all around
This bike is even better than I was expecting. I got the 19” and it’s great. I’m on the taller side of 6’2 and the bike fits me perfectly. I’ve ridden it both with the saddle all the way down and with it fully extended, and it’s great both ways. I switch it up for the different types of riding I do. I also stripped almost all of the stickers off, and I just kept the main “Argus trail” on the top tube and the “M” on the head tube. Everything else is gone and it looks so good imo. Everything works smoothly, and the seat is even somewhat comfortable. And it just looks so awesome. Solid parts and construction, and it came safety wrapped to the absolute limit. Foam sheets wrapped around everything and taped, then cardboard paper wrapped around that and taped, then zip tied together in a box with spacers so nothing moved around. The gears might need some tuning which is normal, but if you don’t know how, there’s videos on YouTube that will walk you through the process. A++ all around and great value for the money Update: This bike is still amazing. I’ve ridden through just about everything you can imagine, except for snow cuz it isn’t winter yet.

Perfect bike for a back country bow hunter
Where I chase elk, E-bikes aren't allowed. I agree with the rule. Too many hunters are super lazy these days, shooting from the road, from a truck, or trespassing through private property. I digress... Anyway, this bike is relatively light. But not the cheap kind of light. The kind of light that comes from lots of R&D where a focus was geared towards building with the highest quality parts, instead of adding unnecessary comforts like shocks.(tires properly inflated are all the suspension you should need... more parts equals more stuff to break or go wrong leaving you stranded or pushing your bike through the back country) the frame is rigid, basic, and bombproof. It shifts through all gears effortlessly, rides smooth and brakes on a dime. Mongoose has been around for a while. I don't think the are going anywhere. There are definitely less expensive options, but you get what you pay for. I am happy with my purchase, and am sure this bike will help me fill my meat freezer for years to come.

Great entry fat bike, but tires need deeper tread
This bike is a good value for the money, and I would buy it again as a entry level fat bike for my child getting into fat biking with me. However it’s not perfect. 1) assembly is not easy. If you don’t have experience assembling a bike it will be tough for you. After I assembled it, the shifting had to be adjusted quite a bit which someone unfamiliar with these adjustments would be totally lost. Same with the disc brakes rubbed badly and I had to adjust the placement of them. 2) it is very heavy, just know that. Comes into play when transporting on a bike rack or climbing an incline, especially for a teen getting into biking. 3) the fat tires are 4.0” wide which is nice, but the tread depth is not very deep. This translates to not the best grip on snowy trails. I’d say maybe half the depth of the tread knobs compared to what came on my Trek Farley fatty. My son slipped out and fell 3-4 times in areas I have grip for days on my bike. But new tires are very expensive, at least $100/tire, so upgrading tires on this price-point bike is hard to justify. If it came with knobbier tires it would be an extremely excellent entry snow bike!! 4) it is very good looking and I’d recommend it for a cheap intro into fat biking. But be weary of the tires if you’re using it on groomed snow trails, but it’s cool!

Junk
It didn't come with none of the hardware to put it together and should have come with training wheels because it was so small. But because I'm a fedex delivery man and just now putting it together it's to late for anything else. 300 dollars for trash. Thanks

17 inch argus st model highly recommend
So far on day 1 it gets 5 stars. Arrived on time without any damages. Assemhly was very easy insert the seatpost/seat, bolt on the front tire, attach your right and left pedals which come with labels because your left pedal is threaded opposite so lefty tighty, righty loosy the right pedal is standard righty tighty. I am about 5,10 185 pounds and the 17 inch frame fits me perfectly! Had to slightly adjust the front break pads to eliminate a slight rub on the rotors but it wasn't hard at all. Out of the box the shifter needed 0 adjustment and shifts very smooth however it is a grip shifter so its a little easy to accidentally shift gears when you aren't trying to. Other than that the bike is very solid and rides very nice the brakes aren't amazing but its easy to swap your brake pads down the road. All in all i highly recommend this bike.

The pops keep happening on the side (so it's not like I'm poking it). Just whenever I take it over something particularly bumpy, a little tear appears and it rapidly deflates.

Well packaged. Easy to assemble. I did notice though, that the rear rim had a dozen or more really small flaws in the paint. By flaws I mean you could see the shiny metal of the rim. Each was about the size of the head of a pin. In one of the cases I cut my finger because the metal was raised up in a sharp point. Front rim was flawless.
