  • Perfect bike for a back country bow hunter
Style: Trail Color: Green Size: 19-Inch Frame
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. ... show more

  • Mongoose 20” Fat Tire Bike
Style: St Color: Grey Size: 10.5-Inch Frame
This has been a pretty great bike. The derailed was a little out of wack but was able to fix easily. My boy gets a lot of compliments on it. Perfect size for my 8 year old with room to grow on it.

  • Such a great bike all around
Style: Trail Color: Green Size: 19-Inch Frame
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. ... show more

  • Really enjoy riding this bike.
Style: St Color: Copper Size: 17-Inch Frame
I was tired of walking for exercise as I hit 65. I was looking for a way that would be easier on my body but still get a good workout. This bike nailed it. Walking had turned boring but even going through the neighborhood. I really enjoy this bike for its easy handling and ride. I had not been on a bike for 45 years. This was easy to get back on track. I ride every morning. Love it ... show more

  • Very pleased!
Style: Trail Color: Green Size: 19-Inch Frame
Let me first say I’m an entry level rider with very little mountain bike experience. 6’ 3”, 206 lbs. purchased the 19” frame. I wanted a bike to ride the neighborhood and do occasional off-road riding. A bike that offered very good stability and control. Arrived today very quickly shipped despite a weather delay. As a couple of other reviewers have said, very well packed and very easy/quick to assemble. Have a couple of very minor owner-assembly corrections. Definitely needs a kick-stand. Although haven’t ridden it yet (more to follow), seems to fit me well. Will change put the seat for a more “senior” ride and probably pull-back handlebars. Overall, very pleased…so far. ... show more
