    • 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

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

    • Just a fun bike.

I really like this bike. The components are fine, they are not top of the line, but nice quality. Came easy to assemble, under an hour. Great ride off road, handles sand and all great. Rode it on the beach. I did make a few modifications to make it a more road cruiser after awhile, but didn't want to give up what I like about a good fat tire mountain bike frame and Mongoose quality. I still have my 1998 IBOC Hybrid and love this brand. Great bike. ... show more

    • 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! ... show more

    • Highly impressed
Style: Trail Color: Green Size: 19-Inch Frame
I have yet to get a good ride in but so far I'm astounded. I'd like my LBS to look it over and adjust but the test ride I did amazed me. I'm coming from a KHS 4 season 1000 that was stolen. Insurance wouldn't replace and I didn't have enough to replace so I bought what I could afford and didn't think I would immediately regret. I have 30 days to test it out, but so far I'm completely astounded. I put it together, and did a few adjustments. And then took it around the yard. First impressions were that it is honestly much more comfortable than my KHS, though I haven't done a 20 mile ride yet. I haven't checked figures, but it seemed a little lighter and more maneuverable? For being over half the price of the KHS this bike so far seems well built and way better value for money. I wouldn't hesitate to buy again, but I'll let a few rides decide if that is true or not. ... show more

Riding a bike into puddles without falling or stuck is what my son enjoys the most. It is perfect for all the back road in our community.

The bike Is good it rides good I suggest getting a air suspension cause it can be very bumpy and I’ve had to replace the brakes levers because they are made of stone or cement

We bought this bicycle for our 10 year old son. He had outgrown his and needed an upgrade so he could keep up with us on the trails. This bike couldn't be more perfect for him. He loves the fat tires because it looks a lot like mom and dad's bikes. The gears were a change of pace for him as his prior bike did not have them. However just a couple of bike rides around the block and he had it figured out. We appreciate the disk breaks as he can stop on a dime. The color is super cool too! He originally wanted an all black bike to match ours but he took one look at this grey color and changed his mind! Assembly was fairly simple. It took approximately 30 minutes and he was out in his first ride. ... show more
