Behold! The Mongoose Dolomite Fat Bike

Behold! The Mongoose Dolomite Fat Bike

It’s hard for me to complain about the Mongoose
Dolomite, since it’s a sub $200 fat bike. No, it doesn’t shift nicely, and yes, it
has one of those terrible seat clamps with the bolts on the sides. It’s precisely compromises
like these that make super cheap bikes possible. So with that understanding, I’ll give an overview
of this bike’s strong and weak points. First of all the paint job is impressive.
Even the rims have a nice red powder coat on them, which does a pretty good job of hiding
this huge weld. The saddle is also quite comfortable. The rear derailleur is from Shimano’s Tourney
group set, which is suspiciously absent from their website. Although I see it available
for $6 on the internet, I think it might be the most expensive part on this entire drivetrain. Speaking of drivetrains, I’ve gotta give credit
to Mongoose for setting this up with a 1x. This makes the bike much cleaner and more
mechanically sound. With that said, I think they should have chosen a smaller chainring
for the front. At 47 pounds, this thing is pretty hard to pedal on flat, let alone on
sand or up hill. I will say though that it’s lighter than my last bike by a full pound—of
course on that bike I packed the components with sand and pumped the tires full of water. The disc brakes suck terribly, but surprisingly
they are totally adjustable like normal ones. Most department store bikes are built in some
proprietary way that makes them difficult or impossible to service. This bike breaks
that trend to some extent. That makes me wonder if a better set of pads would improve the
stopping power. For now, all I need to do is stop pedaling and the bike comes to standstill
pretty fast. I was especially happy to see a threadless
headset. Compared to a threaded headset and quill stem, this feels incredibly solid, and
dare I say—safe. I expect this headset to hold up much better than my last one, and
I also expect the alignment to stay put. I have ridden quite a few fat tire bikes,
and they were generally heavy and sluggish compared to their skinny counterparts. Still,
I was always pleasantly surprised at how well they handled for their size. Not this bike.
Sure, if you pump the tires to 20PSI it rolls and steers well, but it’s then useless on
sand or chattery terrain. Reduce the pressure to 10 PSI, like a real fat bike, and its off-road
performance does improve. Unfortunately, this makes the bike extremely difficult to control,
as the steering pulls whichever way you’re turning. I think this is due to the cheap
tires, which are pretty thick and shaped oddly. I also think wider bars and a shorter stem
would make this bike easier to manage. If you have this bike and want to give it
an upgrade, I might recommend that shorter stem paired with cheap set of 760mm bars. Even after these shortcomings, I firmly believe
this Mongoose Dolomite is a marvel of engineering. Like I said, everything on this is a compromise,
designed to keep it below $200. As a society we asked for a cheap fat bike, and here it
is. It may seem like certain things could have been made better for the same price though.
For instance, would a smaller chainring in the front have changed the price? Well, maybe.
You see these bikes benefit from economies of scale, or using parts that can be produced
in mass quantity. So, it could have been that this very popular crankset/chainring combination
was actually the cheapest route. This scenario is very likely, and is probably the case for
many other parts on this bike. So, we don’t really have the right to nitpick the gear
ratio. So now for the real question; why did I buy
this bike? Why not a nice fat bike? Well, I have some plans which I wouldn’t have
the heart to carry out on a bike like that. If you’ve been following my videos, you
could probably guess that the Dolomite is gonna have a rough week. Stay tuned, because in the next video, things
might get a little salty. Thanks for riding with me today, and I’ll
see you next time.

  1. In Estonia, mongoose bikes cost like 70% of the price of Scott (this bike would cost probably 600€), don't know why they overprice them so much here after importing :/

  2. Guys subcribe my channel for cycle and stunts….i will like your latest vids and give a subs back …shbforsub

  3. what's odd is my Trek Marlin 5 came with the Tourney. It broke while I was just riding around and I ended up upgrading to an Acera. Worth it.

  4. all the parts come from China or Taiwan and they have warehouses packed full of those smaller Rings they just couldn't get a good price on them

  5. My dad owns this bike but we’ve changed a lot of parts we got lighter wheels,custom grips,custom pedals, and a gear ring. It’s great now and we still saved money

  6. Hey Seth I'm one of your really big fans I've watched allot of your videos I was wondering if you had an old bike that I could have

  7. Anyone know what the weight limit is on this bike? I'm trying to lose some weight so I would love to get me a bike to ride to work everyday.

  8. Love the video(s) !!! BTW…..Where in Florida was that last shot taken of them people standing near the exit passage of that massive cruise liner ? I just have to experience that !!!
    Thanks, Gerry from San Diego, CA

  9. Would these be a good bike for wheelies and cruising all around town ??? Anyone know I’m not really looking to trail ride it so is it a good bike for what I want it for

  10. a guy I knew when we were kids had 2 mongooses and a super-goose. Very K bikes. Unfortunately, three kids jump out of a very large rock they were hiding behind with knives to rob us.
    oh well, welcome to the Bronx. Irony, I think the other mongoose he had and super-goose also got pinched. But from what I remember K bikes.
    Van Cortland Park has some really k trails to ride….

  11. good review, but I can feeL all 48 lbs of it !! I dropped an easy 10 lbs, (or 2 bags of sugar) by getting aluminum wheels, I recycled the all steel ones and got 3 dollars as milkshake $$, now at 38 lbs, it handles MUCH better, only other two snags are the horrible seat ( call it birth control cause u will never have offspring if u sit on that nasty seat ) and the pedals are WAY too narrow, I swapped them out first thing, I weigh 137 and wear a size 11 shoe, and my feet are not wide, but those mongoose pedals were made for midget dwarFs , also it's about impossible to use a hand pump on those tires, I use a power air pump for 75 cents and yeah it's worth it , very hard to get air into the valve unless u use a power air pump at a petroL station, I also took off the front brakes to save another pound and a half

  12. Overall, great review: I will add though, most fat bikes will pull hard with PSI under 8-10 ON PAVEMENT. Even $2000 ones. On a "Trail" or sand or whatever, this goes away. Wondering if you have the same problems off the tarmac.

  13. Seth, I want to reduce the rolling mass weight on my Mongoose Dolomite. What tire/tube combination would you recommend at a reasonable price level?

  14. these bikes are great quality.. i have the mongoose brutus fat bike, bought it 5 years ago and its still like new. its really hard pedaling against the wind. department stores arent even selling these fat tire bikes anymore in my area.

  15. I have never owned a fat tire bike but i want to buy the mongoose dolomite it looks like it would be a fun type of bike =) im 6ft 0.5 with shoes on and 6ft 1 with boots on so i would not be to tall for this bike whats the difference between the red and blue rim dolomite

  16. These aren't competition downhill bikes. They're cruiser bikes, but with a few upgrades, they can handle moderate trails. I paid $250 for mine and invested another $200 in upgrades, so far, resulting in a much more capable trail riding bike. Next up, I'll be installing a megarange freewheel and lighter tires & tubes. Yeah, they've got some heft to them, but not a problem for me. Good way to build your muscles up, boys!

  17. I think no matter what bike you ride, what brand is your favourite, what gear you use doesn't matter because we are all mountain bikers and we should unite as one not seperate different categories or groups

  18. All you gotta do is install an electric motor in the rear, hopefully the rim is 36h. Then you'd be stylin' and profilin'

  19. I could choose between this or a nice hard tail Giant with great disc brakes and nice front suspension and after this video I definitely wanted the Giant

  20. Why the intrusive, repetitive pseudo-music? Are you attempting to distract folks from what you are saying? This "music" obsession that YouTubers evince is mighty peculiar !

  21. Some lighter wheels, shimano brakes, a upgraded drive train and some nice tires and it would still be a bargain of a build for a nice beach cruiser.

  22. Mine fell apart on the ride home… Replaced it. That fell apart even more… Walmart made every step of this so miserable that I cannot recommend anyone this bike. It lasted a mont, max. Been rusting out back for years

  23. My bike is not a fat tire bike, but its the one in between skinny and fat. It can hold 65 PSI and it travels pretty quick. Does that bike travel slower regardless even though it can hold probably double the PSI?
