    About this item

    The Mongoose Dolomite 26" Men's Bike provides off-road capabilities and everyday riding performance. The 26" by 4" knobby tires give riders enhanced stability when conquering different types of terrain and the extra width helps riders handle bumps and obstacles in the road. Dual disc brakes help the user stop safely even in wet and hazardous conditions and the seven-speed rear derailleur is highly responsive. Changing gears to tackle hills and other inclines is not a problem with this Mongoose Men's bike because the derailleur works with twist shifters for more control over the gears. The bike has an aluminum/steel frame and alloy wheels for lightweight durability. This navy blue/red bike has style as well and a rider can feel proud displaying it around town. The bike is 38" tall, making it suitable for people of many different heights. Some assembly is required.

    • Frame: aluminum/steel navy blue/red bike
    • Gearing: 7 speeds with Shimano rear derailleur for all types of riding

    I like this bike, it arrived on time, was easy to assemble is fun to ride and people really notice how fat the tires are. I made mine a 21 speed with the addition of multiple front sprockets and a deraileur. I am 6 2 and it fits me well although I did change the bars to some with a 4.5 inch rise.

    At $299, this is a great bike. No, it's not a "real" fatbike, but it's still a lot of fun. The bike was packaged well. No damage or scratches. It was fairly easy to assemble. The only things that needed adjusting were the brakes and the front hub (it was WAY too tight. The tires/tubes that come on this bike are junk and are WAY too heavy. I replaced them with some "real" fat bike tires and tubes and dropped a LOT of weight. I also replaced the stem and bars with some lighter ones i had laying around. With these slight modifications, this is a perfectly sand/mud-worthy fat bike and is a ton of fun. This is nowhere close to what you'll get spending $1k+ on a real fat bike, but it's somewhere to start. Now my girlfriend has a fat bike to tool around on with me.

    I have upgraded both the Mongoose Beast and the Mongoose Dolomite, the bikes have the most innovative frames and that means lots of room for customizing. I can easily see that these bikes are a big hit and I think that Pacific bicycles wouldn't discontinue the Beast model, it is a great beach cruiser bike that works great with high rise handlebars and banana seats. A lot of those who buy these bikes add all sorts of different seats and handlebars to them. To say the least, the new fat tire bikes have started a whole new fad for bicycles, reminds me of the Schwinn Stingray glory days when bicycles were all about making a statement of individuality. Over all, the geometry and the style of the bikes are very nice and the bikes really stay on the ground. Love the tires and the style of tread they have. The main change I have made to both the Beast and the Dolomite are the gear ratios. I believe that these bikes need to be geared lower. Everyone that buys these bikes are changing the sprockets and the freewheel cassettes to lower gear ratio range combinations. I swapped my freewheel cassette to a Shimano seven speed Mega-Range 14-34T. Model MF-TZ31. I found that I needed a "granny gear" for hard to trek through places at low speeds. The rear 18 tooth gear cog on the Beast, well, I swapped that out for a 22 tooth cog. That made the bike easier to peddle and to get over stuff at low speeds. I love the bikes, though, don't get me wrong. They are a great addition to my bike collection and I'm sure a lot of changes will be made in the future as a result of the mountain of feedback you will undoubtedly be getting from your customers.

    How heavy is this thing? Thinking of getting it and mostly upgrading everything to try and get it under 45lbs....think this is possible?
    by wbt85 3/11/2014
    • It ships at 51 lbs. I swapped tires/tubes, bars and stem and have it down to 42lbs. A new seatpost, seat and cranks would drop a few more, I'm sure. Drilling the rims would help, too.

    • About 50 lbs. Instead of upgrading, do a web search. There are fat bikes with reputable brakes and derailleurs, WITH ALUMINUM FRAMES, that start at $399. The frame will save a lot of weight. Also check the tires and tubes. I am still riding on the original Mongoose tires and tubes but they are heavy.

    • Mine was 48.5lbs. New 60 to 120 tpi tires & bar will shed at least 5 lbs. I use a Vee Mission on back & Devastator up front.

    • the first thing to do is change the tires they weigh almost 3000 grams a piece a good set of tires will save you 6 pounds, I have knocked off as much as 15 pounds of the beast

    • The tires and tubes are super heavy. You can cut 10 pounds easy by installing new tires and tubes. Reducing the rotating weight can really improve any bicycle ride. The other super heavy part is the crank. My Beast weighs right at 50 pounds and the Dolomite is basically the same bike with more parts added (brakes, gears, cables, levers) so has to weigh more than that.

    • The bike weighs 49 pounds on my scale without the kickstand but with Shimano's 520 SPD's on there. Methinks if you...... 1) Drill out the rims (1.5") double holes per spoke bed 2) Replacing all the steel parts with quality aluminum 3) Replace the ti(y)res with lightweight supple high TPI's 4) Go tubeless or use 2.5" MTN tubes ......you can easily get the bike in the mid/high 30 pound range. As far as money goes, is it worth it? I fortunately have bins and bins of parts to swap out so it will only cost time. The ti(y)res I gotta eat though. Worth.

    • About 50 pounds. Mine weighs 52 pounds, but that's because I added headlights and a bell to it, different peddles.

    HI, Please verify what material the Mongoose Dolomite bike frame is constructed from. The specifications state that it is aluminium, but the pictures clearly show a steel frame. Thanks so much.
    by Tater 3/4/2014
    • Steel

    • It is all Steel Frame. I don't know why they list it as aluminum/steel ? The wheels I believe are aluminum but not the frame.

    • Cranks are cast iron and weigh a ton. Brake discs are steel. Brake calipers are aluminum body with steel hardware. "Alloy" is 2 or more elements combined. Steel is made from Iron and Carbon so technically steel is an alloy.

    • Steel frame and forks. The wheel rims appear to be aluminum, the crank arms as well.

    • Zeigenfoot said: " The frame is steel. The wheels are aluminum. That's what they meant by, "Steel/Aluminum."" The notion that any manufacturer would note the material of the rims under frame specs is dumb of them at best and deceptive at worst. They clearly state that the rims are alloy in the rim specs. There is no need to restate these specs so confusingly under other specific specifications. Show me any other instance where the rim material is listed in the frame specs by any manufacturer. Pacific ought to correct this listing and the Massif listing so people understand what they are actually buying. Heck, Pacific Bicycles own pictures that they were spreading around the Web prior to the release of Massif shows it with an aluminum frame and steel fork. Note that Pacific does not list any of their aluminum frame bikes in such an asinine way.

    • The frameset is steel. The only aluminum parts are the rims/stem/brakes/discs/crank. Everything else including the hubs is steel.
