    Got it.
    Assembled.
    First ride.

    We shouldn't have to say this, but for safety and optimizing the longevity of the parts (or in some cases, just so it will ride), check, grease and adjust everything before you first ride it. Typical culprits are Bottom Bracket, Front Hub, Rear Hub, Head Set, Brakes.

    Recommended Upgrades
    • Bottom Bracket: $10 YST BSA Cup & Bearings, with seal to spindle shaft
    • Optimum bottom bracket (hub too) bearing torque = zero torque, yet with zero play:
    • Freewheel with a granny gear:
      Shimano Megarange: 13-34T or 14-34T
      But they're "Alpine" gearing; they swap out their 28T for the 34T, so there's a big gap to the granny.
    • custom stack of a 34T megarange
      Allows you to put a 28T back in, for having a 28T and for smoother gear progression across the range.

    • Alternate to a custom stacked 34T megarange freewheel
      7 speed vs. 8 speed freewheel
      Allegedly the Sunrace and others that fit are inferior quality to the Shimano (softer metal? bearings don't last as long?), but... the 8 speed has the same physical spacing between the gears, so the stock derailer can access 7 of the 8, so it's a straight swap in (subject to chain length for larger gears)
      13-15-17-19-22-25-28-34T usable 15-34T or a 11,13,15,18,21,24,28,34T usable 13-34T and some others.

    • Triple Mtb chain-ring:
      Pretty much essential for trail riding, or have hills, or other than packed snow on the flat or packed sand on the flat.
      22-32-42T, typically manually selected by moving the chain to the 22T for hills/trails/snow/sand or 32T for road.
      Then if you find yourself changing a lot, then look to adding a front derailer.

    Popular Upgrades
    • better tubes: roll easier, lighter too
    • better tires:
      120 tpi tires roll easier, better grip, lighter too
      Huge improvement to the quality & enjoyment of your ride.
      On-one floaters seem to be the most popular of the less-expensive all-purpose fat tires.

      Start of list of tires people have put on a Dolo
    • Easy to knock 7+ lbs. off the Dolo's weight with new tires & DH tubes.
    • trigger shifter:
      Some prefer triggers, some don't.
      Shimano SIS 7 speed compatible.
      One example that works)
    • Better brakes (like the Avid BB7)
      And larger rotor size recommended for anything other than cruising use on flat terrain, or for clydes. Why larger rotors for your fat bike.
    • Better brake levers (Avid Speed Dial levers are a nice indulgence ($14 to $40 depending on source), but overkill)
    • Better seat, different bars

    Brakes work, shifter works, bearings lubed.
    Front axle was locked tight.

    Very well packages compared to the way the Beast was boxed. Many tubes protected with thin foam & card-stock overtop.

    Calipers are not up to my BB7 set, but they work and so far are smooth.

    Rolls better than the Beast. Appears to be the same tires. I'll measure tomorrow.

    Thanks for posting it. Sitting here hoping they are back in stock soon. Probably would ride better with the stem out front, but who am I to presume to know what you like? What if you're a vet with an arm missing or something. Ride your ride dude, it' all yours after all.

    Hate to "ruin" it, but I'll be needing cruiser bars & an adjustable stem, and a set-back seat post...
    Not a vet, just back and other medical problems.

    Hey there. Me, I use a BMX handlebar, leaned back a little. That's what makes me able to ride at all. You might want to try that, Canoe.

    For the money, that is a great looking bike! I say get some ape hangers so your back doesn't hurt and ride the heck out of it. Please let us know how you like it after a couple of rides. I am thinking about buying one for when Dad comes to visit!

    A few more quick points from that short midnight ride.
    • Headset was wonderfully smooth and liquid (during assembly, and while riding at a few degrees below zero). (I've never seen this in a bike below $800, but my experience is limited)
    • Tires measure identical to the Beast tires, from the outside anyway. Have to pull one off to weigh it and the inner tube. At this point, no idea why the Dolo rolls so much better than the Beast. Tires smell, but no where near as bad as the Beast tires.
    • Wheel seemed stronger, more robust, confidence inspiring.
    • The 36 spokes are straight gauge. Couldn't find my dial calipers, but the plastic vernier one says the black Beast spokes are 1.6mm and the shiny steel Dolo spokes are 1.8mm.
    • By hand squeeze & plucking (no meter), spoke tension is good. Front wheel is tensioned slightly more on the LH than on the RH. Rear spokes have more variance in tension and their RH has meaningfully more tension. A quick look has the rims appearing to be both laterally & radially true, and it tracked nicely in that short ride.
    • No spokes creaked or cracked: appears that the wheel was properly stressed to seat the spokes & nipples as part of the build.
    • Some of the welds aren't ideal smooth waved pools, but while having to judge with paint on top, they appear strong enough.
    • The factory has taken care with the shiny paint. Not even fine surface marks from wiping with a hard cloth. I'm sure I'll fix that before too long.
    • When unpacking, I only found one small chip in the paint where the foam/card-stock shipping protection didn't extend quite far enough for whatever chipped the paint. Tube is not dinged.
    • The blue paint is far more attractive than the wallyworld photos show. And I had assumed I'd be stripping the paint off of the rims, but with it standing in front of me the bike looks good. So good I didn't even pull the decals off! (grumble grumble - I hate decals)
    • Brakes & gears obviously setup at the factory and worked out of the box.
    • Gears changed perfectly at the start of my short ride. By the end, it wouldn't go into 7th. I assume this is due to a new cable stretching.
    • Geometry is different from the Beast. The top of the head tube is much closer to the ground. ~1" closer. Riding, the Dolo seems downright "petite" compared to my Beast and a pugs with Larrys I've tried. A strange sensation to have for a fat bike.

    This is only a first look, and one bike, and no record of use, but this bike might be a real sleeper.
    And for $225.

    Hope to get it back outside sometime today to get some real photos.

    I don't have enough experience to judge that. I have to ride sitting straight up anyway.
    What points would you like measured?

    Photo showing measurement points.
    NOTE: photo was taken with a wide angle lens, fork turned, etc.. It is impossible for a photo to be "on axis" for every part of the bike, so do not try to do a relative measurement of the photo nor take angles off the photo and expect them to work.

    Grabbed a couple of shots when I took the Dolo outside today for a side shot for the measurements. In the sun, it's too contrasty to bother trying to get good detail shots. But here's a few to show what it can.

    I thought about that too. Just for the sake of stating it, it may be possible to get reasonably correct angles off a photo if you use a telephoto lens and stand way back. I have an 800 mm equivalent lens on my Nikon V1 so if I backed up a few hundred feet it might be pretty orthographic, if that's the right word.

    • Front brake cable -- fully housed to the caliper.
    • Rear brake cable -- housed, except where it runs on the underside of the top tube, running open between stops at each end, exposed to crap up off of the front wheel, with only the down tube to shield it.
    • Shift Cable -- housed from shifter to a stop under the top tube, open running beside the rear brake cable to its stop, then after a short housing over to a stop on the drive-side seat stay, runs open straight down the seat stay to a stop, then housed to take it to the derailer.

    (~edit.: at least on this Dolo)

    yes, standing off and optical zooming in would give a more accurate on-axis image, but only more accurate, not accurate. But even with the snow to reflect light into the shadows, with the direct sunlight the contrast was too high to make that worth doing today. Look how hard it is to pick out detail in those photographs.

    This might help...

    These photos might help to undefined illustrate some differences in the frame layout between the Beast and Dolomite.

    As orthographically as possible (yeah, that's the right term, hehe), I've put a Beast (in red) behind a Dolomite. The angle is not perfect, obviously, but you can see some clear differences that backup what Canoe has basically already said...

    The Dolo in the (semi) wild - Mongoose Dolomite-20140306_153447.jpg

    The Dolo in the (semi) wild - Mongoose Dolomite-20140306_184804.jpg

    The Dolo in the (semi) wild - Mongoose Dolomite-20140306_184921.jpg

    What may not be obvious is that the wheelbase on the Dolomite is almost an inch longer.

    In the photo of the two BBs, the rear axles are lined up, so you can see how far aft the BB on the Dolomite has moved. The chain/seat stays are shorter, and the top/bottom tubes are longer.

    The head tube on the Dolomite is much lower, and almost an inch forward of the Beast's head tube. So, the forks are shorter as well.

    In the rear shot of the bikes, you can see that the Dolomite's rear dropouts are significantly farther apart than the Beast's.

    I also think that the Dolomite's rear rim is not centered between the hub's flanges (is that called asymmetrical lacing?) to make room for a 7-sp freewheel.

    On the new frame, the BB is farther aft, and the head tube is slightly forward, so my feet don't rub on the front tire like they sometimes do on the Beast, while pedaling through a turn.

    I did a test ride with my brother, switching back and forth. We rode mainly on tarmac, and a bit on grass. We were hard-pressed to pick a favorite, handling-wise. The obvious differences are the bars, the brakes, and the gears. The Dolomite has its "upgrades" over its predecessor, and the Beast has raw simplicity on its side.

    I honestly don't know yet which one I like better..

    Re: The Dolo in the (semi) wild - Mongoose Dolomite

    I had the Beast - changed the rear cog, quill stem, pedals, and handlebar. It was heavy so I never rode it on the trail - didn't want to walk up the hills.

    I sold it and bought a Framed Minnesota 2.0. I was surprised how much less it weighed compared to the beast. The weight of the Minnesota feels like my Trek HiFi full suspension 29er.

    I was going to buy a second set of wheels for the Minnesota but it looks like I can buy a Dolomite for the same price as the wheels. Any idea how much the Dolomite weighs? How does it compare to the beast it terms of weight?

    The shipping waybill says 49 lbs..
    Bathroom scales say the bike is 50 lbs.., but it does have a tiny front light and some dirt on it now...

    When I get the time, I'm going to pull the tires and weigh them and the tube. Going to try split-tube tubeless to see how that rolls with losing the inner tube.

    I took near 4.5 lbs. off my Beast with a DH tube and a Larry on the front, along with a token contribution from a drilled rim. Do front & back, for near 9 lbs. off. (assuming it's the same tire & tube weight as the Beast).
