Good bike for $280. Comparison to other cheap fatbike, the Northrock XC00 at Costco that is currently $499 online and $399 in the store (if you can find one):

Mongoose Dolomite (manufactured by Pacific Cycles):
- Steel 17" Frame. Standard (symmetrical) 190mm rear and 135mm fork spacing. Straight (34mm ID) head tube with an external cup headset for a 1 and 1/8" straight steerer fork.
- The bike weighs ~45 pounds.
- 1x7 gearing with a Shimano Tourney or Microshift 7 speed derailleur. Twist Shifter. The freewheel is a 14-28t.
- 100mm wide 36 hole alloy wheels with open bearings, and bolted on axles. Chaoyang/Arisun 4" tires.
- Offbrand mechanical disk brakes that don't feel the best, but are somewhat ok if properly adjusted.

Northrock XC00 (Manufactured by Giant) (https://www.costco.com/northrock-...67336.html) :
- Alloy 17" Frame. Non-standard 170mm asymmetrical (15mm driveside offset) rear and 121mm fork spacing. Tapered head tube with an integrated headset for a 1 and 1/8" straight steerer fork (it actually comes with a straight steerer fork).
- The bike weighs ~35 pounds.
- 1x7 gearing with a Shimano Altus rear derailleur. Trigger shifter. The freewheel is a 14-28t.
- 57mm wide 32 hole alloy wheels with open bearings, and quick release axles. Kenda Gigas 4" tires.
- Tektro mechanical disk brakes that will feel better than the offbrand ones on the Mongoose.

Out of the box it would seem that the Northrock is slightly better specced, as well as having a more modern and lighter frame. The controls on it will feel better, and the brakes are slightly better. However, the Mongoose functions better as an actual fat bike. It has much wider rims, and tires with a more aggressive tread that are better suited for trail/sand/snow. The tires on the Mongoose, while being the same width as the Northrock, will actually measure out closer to the full 4" due to being installed on wider rims.

When it comes to upgrading (if one wants to embark on such an endeavor on these bikes), the Mongoose is slightly more upgrade friendly due to having standard frame and fork spacing - making it much easier to upgrade the wheels. However the Northrock can theoretically take a tapered fork, but that will require a new front wheel (due to the non-standard stock fork axle spacing and hub), as well as a new headset.
Not sure why people are downvoting this. The Dolomite's have been insanely priced since Covid started. People were selling these for $500-$600 and more local and on Ebay. This is a good price in the last 2 years for this bike.
Honestly thank you so much for posting this, I wanted something for exercise, and always wanted a fat bike, I remember seeing them $199 3 years ago, I bit the bullet and purchased one for $399 and fell in love. I've upgraded the pedals and seat, doing a Caset and other upgrades. Long story short I'm ordering one for my wife and brother. Thanks again.

I was gonna buy this bike but went with the Malus thinking was gonna be better but ended up selling it cause it's super heavy and all components are cheap as hell. So if you can get this for less than 200 go for it but you gonna have to upgrade lots of parts. Otherwise just get a northrock fat tire bike from Costco I got one cause is light and has better parts.

I've had both bikes, this mongoose (ended up selling) and the Northrock xc00 (now my 'loaner' bike I keep for friends). If you're planning on upgrading, I wouldn't recommend starting with the 'goose. The stock wheels are absolutely garbage and even with upgrades you'll be severely limited.

The stock wheels on the Northrock XC00 however, are at least serviceable. If you can find it, it's worth spending the extra money on an XCF. You can at least upgrade an xc00 to similar spec for about the same money, but a lot less hassle. If you can live with the entry level drivetrain (or are good at wrenching and ebaying and can upgrade to older, but higher quality spec 9 speed stuff for relatively cheap) and the weirdly short cranks, getting a set of decent tires would get you most of the way towards what I would consider a reliable, enjoyable fatbiking experience.
This is a bit misleading. The wheelset on the Dolomite is just as serviceable as the one on the Northrock. The bearings are regular serviceable ball bearings that can be repacked.

Secondly, you cannot really upgrade the drivetrain to a 9/10/11/12 speed on the Northrock as is because it's a freewheel setup, not a cassette. The best you could do would be to upgrade to a 14-34t megarange 7-speed freewheel on the front and a crankset with a smaller cog than the stock 36t on the front for better climbing. Upgrading to a cassette on the back would require a new rear wheel with a freehub, or at least a new hub. Getting a new rear wheel for the XC00 would be next to impossible, due to the non-standard asymetrical spacing, and installing a new hub would be more difficult for the same reasons.

Most of this also applies to the Dolomite, with the exception that one can actually source a new rear wheel. As a matter of fact they are available directly from Mongoose for around $50 from their higher end alloy models with a freehub already installed which is ready to take a 8-12 speed cassette (direct drop in).

Putting that technical bit aside, I do agree that if one is content with riding this as a 7-speed, the Northrock XC00 would be the better bet due to the significant weight difference. Regarding the XCF - it is a much nicer bike for just a bit more money than the XC00, but I haven't seen it available in the US.

Quote from AaronA1523 :
If you're getting this you should get new handlebars and maybe think about upgrading the tires to something more serious (if you're going to actually take it out in snow and ice). I do think you might be better off getting something a step up from this that's a bit lighter that comes with better tires and wider handlebars though. Like, from a functional standpoint, I kind of think this mongoose is limited as a fat bike. That costco bike people posted seems better, as do some of the motocambene (etc.) fat bikes. I just watched a couple of reviews and the problems with this one are going to make it a lot less fun and functional than some of these other options. I say this as someone who has a salsa beargrease (and a felt cx bike, and an old steel bike I re-did) and the beargrease is like my favorite thing. You don't need anything that fancy, but I do think this is missing some of the "stuff" that makes a fat bike good in terms of geometry (handlebars especially), tire quality (they aren't going to handle snow or sand), and gear set (which is going to end up being a pain if you ride regularly as that nonsense is going to break like ASAP). Just a thought. It might be worth saving up another $200 for something in the $500 range.
Clearly written by someone that never owned one of these. While it is heavy and a bit hard to upgrade, the stock Chaoyang tires that are currently on this bike are actually ok in the Sand and Snow. Much better than the Kenda's on the Costco Northrock XC00 (which is more of a hybrid tire).

The Dolomite wheels are actually *more* serviceable (the sealed bearings on the northrock aren't at all - they're sealed bearings which as far as I can tell, aren't removable unless you have a blind bearing puller. They'll last longer assuming similar quality level, but once they're done the wheels would need new hubs), but the problem isn't the quality it's that the dolomite wheels are HEAVY as sin. I realize it's mostly because of the narrower profile but the northrock ones are surprisingly light. They also use stainless spokes and nipples, which is nice, not sure what the material is on the dolomite.

As for the freewheel, yeah it's an inherent disadvantage but you CAN put a 9 speed freewheel on there. I have one right now and it works just fine. They're a little pricier than a standard cassette but mine survived 2 winters of commuting every day with no isssue. Older, high quality 9 speed parts are relatively cheap and actually available. You can even get a rear derailleur with a clutch.

In normal times, It'd be hard to recommend either since pre-covid you could easily find used 'good' entry level fatbikes for 600-700 but those days are long gone.

I was replying to your post that said the XC00 stock wheels "are at least serviceable", so...

The wheels on the Dolo are the worst on any Mongoose fatbike. They are alloy (with what I think are stainless spokes on the current Dolos), but are solid 100mm wide. At least on the Malus they have cutouts and are lighter. I've purchased an entire wheelset from Mongoose with cutouts, a freehub, and QR skewers for < $100 shipped, but who wants to spend even that much on a $280 bike...

The XC00 on the other hand doesn't even have proper fat bike rims at 57mm. IMHO they don't give the correct profile to 4" tires for snow riding, where you need max contact patch. I wouldn't go lower than 65mm on fat bike rims, and really 70-80mm would be ideal, and is used by most major bike manufacturers.

Anyway, I agree that both bikes are a bad recommendation for anything other than short distance recreational riding. Really, nowdays one would need to spend about $1k to get an entry level fatbike that's trail worthy out of the box. I mean something with a decent alloy frame, 1x10 drivetrain, basic hydro brakes, and snow worthy tires.
