Top Amazon Reviews

πŸš€ Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The bike, due to its wide tires and sturdy build, is well-suited for larger people and provides a comfortable, albeit somewhat challenging ride due to the tires' size. The assembly process is generally straightforward but could benefit from clearer instructions. The bike's handlebars' height adjustment is somewhat limited, which may create discomfort for taller riders. Several users have praised the bike for its value for money, especially when found on sale.

Pros

  • πŸ‘ Sturdy build, suitable for heavier riders
  • πŸ‘ Provides a smooth, comfortable ride
  • πŸ‘ Value for money is praised, particularly during sales
  • πŸ‘ Wide tires add to stability, although they may make turning and getting started a little more challenging

Cons

  • πŸ‘Ž Assembly instructions could be clearer
  • πŸ‘Ž Handlebar height could be limiting for taller individuals
  • πŸ‘Ž Certain parts, like the pedals and reflector, may need to be replaced due to quality issues
  • πŸ‘Ž The wide tires can make the bike slightly hard to turn and get moving

Should I Buy It?

Yes, if you are a larger individual seeking a comfortable, stable bicycle and don't mind a few minor quality issues and limited height adjustment, this bike could be a great fit, especially if found on sale.


  • Loving the fat bike.
OK, so its not really a 5 star bike, but when you factor in the price its great. I have a pretty nice 29'er that I had been riding and kicked around the idea of getting a fat bike just for grins and giggles, and when I saw it on clearance I jumped. The bad first, the bars are really weird to me, got rid of those and replaced the stem while I was at it. The twist shift is terrible, put on an old trigger shifter and it works 100% better. Some have complained about the crank, but I thought it wasn't that bad and the rear derailleur was OK, too. Brakes were fair, but I plan to upgrade to larger discs and hydraulic. I was surprised at how light the front wheel was, I thought by the reviews it would weigh a ton, but not really. Seat post was pretty cheap, but seat wasn't that bad if you are used to a mountain bike seat. I took this baby out on some pretty tough trails and was really impressed. I have ridden a lot of off road motorcycles and this is what it reminded me of the way it handled. It would roll over things like they weren't even there. The rolling resistance is a problem on long hills, but not that bad on lesser inclines. The gearing is pretty tall for trails, but its taking me back to when I rode a single speed and it forces me to ride more aggressive. I have a Megarange on order, but I am kind of getting used to the taller gear and liking how it is forcing me to be more aggressive. I took it out today in a light rain, trails were nasty, and it went right on like nothing to it! I don't see it replacing my 29 for faster trails, but for a quick workout around home I love it. Its a ton of fun for cheap and well worth the price. EDIT: After giving this thing a good beating, I still love it! I have added an old set of hydraulic brakes that made a big difference, stops 100% better now. Also the Megarange rear cassette helped a lot on steep hills. Taller, lighter seat post made it fit me a little better, too. My 29 sees very little use now, this gal gets all the attention. Its given me a lot more confidence that I have on my 29. The wheels/tires may be a bit heavy, but the flywheel effect you get from that lets you just roll over stuff you literally have to try and hop and pedal over with regular tires. ... show more

  • Fat Tire bike for less than $250? "add to cart..."
Simply put, this is a fantastic fat tire bike for the incredible price of less than $250. I've already put in over 60 miles in the last couple of weeks, and it's just a joy to ride. I was pleasantly surprised at the power/torque this bike has when tackling hills. I was a bit worried about how it would handle steep inclines given its weight, but man... the first steep elevated trail bridge I climbed, I easily outpaced others who were riding multi-geared road bikes. This puppy can also easily take off from a standstill with little effort. I was originally looking for a bike with a smooth ride for suburban/trail biking, and this has proven to be exactly what I wanted. This is by far the least expensive bike I've ever purchased, but it's also the MOST FUN I've ever ridden! I'm sure the $2,000 - $6,000 fat tire bikes would smoke this in a heartbeat, but seriously... for under $250, this thing over-delivers! Rides really well on paved and gravel paths. Plus, it's always a hoot to hear the various comments from others who've never seen a fat tire bike before! Is it perfect? No. The one thing I would recommend that everyone upgrades immediately is the seat. I know that bike seat comfort is highly personal and subjective, but I found the factory seat to just be rock hard and uncomfortable for any ride over a few miles. So for another small investment of $45 for a quality seat, I'm sitting comfortably at 20+ mile rides with no complaints. Pros: - Low cost but solid quality - FUN to ride. There's nothing like fat tire biking. - Nice power/torque. Easy hill climbing and quick take offs. - Fairly easy to assemble. Cons: - Factory seat is a bit hard. Recommend replacing ASAP. - Mine was missing a nut for the front tire assembly... minor inconvenience though. Summary: - Looking for an intro to fat tire biking? BUY THIS. You won't regret it. ... show more

  • A great bike except for some shipping damage.
I wish I could give two separate grades: one for the quality of the bike (excellent -- five stars) and another for the quality of the shipping (terrible -- 1 star). The assembly was easy, and the bike rode very smoothly after I got it all put together and rode around for six miles. The only problem was that I had difficulty shifting downward to any gear below the 4th. I then noticed that the bike was damaged in two areas: slight warping of the two plates that surround the big gear between the pedals, and warping of detrailer metal plates and the nearby left dropout area of the frame. When I examined the cardboard box the bike was shipped in I found "bruises" (circular tears around 6" in diameter) adjacent to where the two areas of damage were. It appears to me that the package had been impacted in a way that caused the two widest areas of the bike inside the box to be hit hard. Perhaps the package had been leaning against a wall in a warehouse and a fork-lift backed into it. Except for the slight problem with shifting to the lowest three gears the bike was still functional so I wasn't very concerned about these problems until the next day, when I started to ride the bike and shifted from 4th gear to first and continued pedaling. I then heard clashing of metal parts and felt the chain derail. I stopped the bike, got off it and examined the rear derailer. I found it had become so warped that it no longer could function (the uppermost gear of the derailer mechanism had warped inwards towards the spokes to an angle around 35 degrees away from straight up, making it impossible for that gear to move the chain). I had to walk the bike back to my house, which was around 100 meters away. A harsh lesson seems apparent: I should have done something to correct the warps in the derailer parts before riding the bike any more. I've been able to correct the bend to the rear left dropout. I removed the rear wheel and placed the bike on its left side, then rested the left chain stay on a stack of three house bricks (such that the left rear dropout extended a couple of inches over the edge of the pile of bricks). I then grabbed the left dropout with a large adjustable wrench and pushed hard downwards. The dropout (which had been bent inwards towards the rear tire around 3mm at the dropout's end) became straight again. The warps in the two disks around the pedal gear don't seem to need straightening The warps in the long metal plate of the rear derailer appear to me to be far more difficult to correct. I tried to use the amazon site to ask the bike maker to send me photos of a normal, undamaged rear derailer to help me make the needed corrective bends. The amazon site seems to allow no way for one to send such a request to the bike's maker. I used the option of asking to make a return to send my simple request (for photos) with the message-entry blank, making it clear in my message that I only wanted some photos, and did NOT want to return anything. While doing this the web site bizarrely logged me off twice (I'm certain I did nothing to warrant this). ... show more

  • A Solid Entry-Level Fat Tire Bike For The Average Joe
Color: Silver/Yellow
This bike really surpassed my expectations. I based my purchase off of other reviews found here on Amazon and thought, well this bike should be OK and expected there to be things that I would simply have to deal with since it was an entry-level priced Fat Tire Bike. However, it worked perfectly right out of the box. Now I did do some minor customizations to suit my preferences, but they honestly weren't needed. Those changes were that I replaced the stock seat with a larger more comfortable one. The stock one is of pretty high quality. It's just a bit small and hard like all of the other stock bike seats out there. I swapped out the straight mountain bike style handlebars for custom cruiser handlebars to allow for a more erect sitting position. In changing out the handlebars I found that unless you have immense patience and perseverance then it's easier to simply replace the stock handgrips with new ones. I chose comfort grip handgrips that help alleviate hand fatigue or carpal tunnel syndrome. They worked perfectly. One thing to note here is that I didn't need to change out the shifter lines or brake lines at all like others said when they modified their bikes. I found that simply rerouting the cables slightly left ample line length on them to reach the new handlebars. Before you ride I suggest using some Light Spray Oil On the chain and other moving surfaces. Except for the brakes of course. I also suggest pumping up the tires to the maximum pressure listed on the sidewall if you happen to be riding on paved roads or happen to be a person like me who weighs over 200 pounds because the tires do have a lot of flex at lower pressures and will bottom out on the rim at lower pressures with riders weighing above 200 pounds. The gears do shift really smoothly. However, I will admit that having only 7 speeds is taking some getting used to, but for the average person who goes off road only occasionally, seven speeds are enough. It also does not feel like it's a heavy bike at all. It's obviously a bit heavier than my Schwinn aluminum frame mountain bike, but that is a serious off-road mountain bike. I bought the Mongoose Malus for cruising parks, boardwalks, and my neighborhood. That is where this bike seems to shine because it is really comfortable and an uncomplicated ride. If you're looking to get onto a Fat Tire bike to see if you like it but don't want to break the bank then I can comfortably say that the Mongoose Men's Malus Cruiser Bike is a fine way to do that. If you're a professional bike rider looking for some fat tire powerhouse bike to storm through incredible terrain then you certainly won't be interested in this bike, but then again hardcore bikers looking for specific name brand bikes probably aren't shopping for their bikes on Amazon anyway. Take this review for what it is. One person's opinion of a bike that they like for what it is... A solid entry-level Fat Tire Bike for the Average Joe. Peace. ... show more

  • Way better than expected!
Color: Matte Black
This bike far exceeded the reviews I read. I had it on the road within an hour after it arrived and started assembly. The instructions are a little inconsistent, but it was so well put together out of the box it didn’t matter. Once it was all together, it rode great! It’s only been six or more hours, but I am really impressed having owned Trek, Stumpjumpers and Canondale. The only damage was a broken reflector (as if I use them). The stem is a little short but not critical for a bike in this price range. I would consider this more then entry level at a extremely reasonable price. More to follow. This is first impressions. ... show more

  • Good bike. Perfect source for conversations.
Just purchased another one. I am converting these to e-bikes. Inexpensive, robust a very good entry level fat bike. And an especially good candidate for my use. Nothing lightweight about it. But you're adding a heavier motor and battery. I like the steel frame because it is strong and I can cut and weld the bottom bracket. That cures the motor mount problems (weld it to the frame) and chain alignment issues. I gear these especially low, the chain wheels have no offset so I cut the bottom bracket to the required width. Everything else that is of questionable quality gets replaced. And surprisingly that is very little. Brake pads, rear axel, ball bearings at both wheels and inner tubes. And these parts were kept on the bike until the heavier, more powerful conversation wore them out. Everything else is good. I rode it as a bicycle for a bit before the conversion, even put on a 3x mt bike chainring to lower the gearing, to high stock. It was fun. But I'm 9000' in the Rockies and the conversion was the main intent. For the money you cannot go wrong. ... show more

  • If you know what you're getting into, it's a decent purchase. Cheap, but works.
Let's be honest here, if you're looking at a $230 bike, you shouldn't be expecting much. I wasn't. But I wanted to keep active this winter and thought this would give me an extra measure of safety while biking as opposed to my more expensive, but less fat, mountain bike. Pros: Cheap. Seriously. Gives great handling in snow. Cons: Only one bottle holder? (not included!) No rack mounts in back. Zero handling advantage on ice (I've already wiped out twice). Grip shifter. I prefer thumb shifters, I had quite a hard time getting used to this one, I consistently would accidentally switch gears when getting an extra grip for power pedaling. Neutral: no front shifter? I dunno, sometimes I wish I had more gears and sometimes it doesn't really seem to matter. This will take more pedaling power than a mountain bike. I haven't had too many cases where I've said, man, I really NEED more gears. They'd be nice, but not necessary. Setup was simple enough, I guess. But I had a really hard time getting the front brake to quit squealing. I finally got it dialed in but the whole thing just felt wonky so I brought it to the bike shop to have them do everything they could. Which actually wasn't much. The guy said it pretty well: cheap parts, don't give a lot of option. So the brakes are a little spongy, the calipers squeal a little bit, I've crashed a few times. But overall, and I don't mean to sound 100% negative here, I'm actually quite satisfied with this purchase. I needed a cheap bike to play on during the winter, this does better than my other bike does on snow, and the cons aren't super terrible. If you want to do some light riding in the winter, or on sand (this also does great on gravel trails), then it's a good purchase. If you want to run competitively downhill trails, you probably want something with more stopping power. ... show more
