  • Great Bike at Their Sale Price
I had seen this bike for close to their list price for a while, then I happened to see it at $426, and I bought it. Great bike for that price. Acceptable bike for a few hundred more. But at less than 500, this is a lot of bike. The bike rides pretty well and I'm happy I bought it and would buy it again for that price. I looked at the various Mongoose mountain bikes and bought the Juneau because it has a front derailleur, rather than being a 1x. (Pronounced "1 by".) Reviews for the other bikes (Dolomite, Aztec, Malus) indicated that people couldn't climb hills b/c the bikes were geared too low. This is true. The Argus is a 1x, but you can climb with it b/c it has a 42 tooth (or thereabouts) gear in the back. Just compare the photos of the Argus to the other 3 and you'll see they all have a tiny cassette of gears in the back. The Juneau also does not have a big gear in the back, but with the extra small gear in the front due to the 2x setup, you can still climb. This is a good bike. It's quite light for a fat bike that cost me less than $500. The components are not great. The brakes in particular... they do stop the bike but if I were going to use this thing over time I'd want to replace those with hydraulics. I wouldn't got down anything too steep + long (like a 1 kilometer consistent steep descent) with this either, because those brakes feel like they could burn out and leave you helpless. But for just riding around on some local trails, without trying to win a race, they're okay. And the bike itself performs well. The gears too and shifters are basic, but work. I didn't need to tune them. They worked out of the box. I took it on a regular trail that is not frequently ridden by bikes, and overgrown. The bike did well. I went right over a bunch of stuff. The bike performed fine on some basic hills, and roads. The seat is not comfortable. That will need to be upgraded. Luckily I have some lying around. The handlebars are... this is always a personal thing, but to me they're too straight. I'd like to get some a little more swept back. You can mount a single water bottle to the bike, but not more. That's a bit lame. Overall, for the price, I'm happy with the bike. An aluminum fat bike that is less than 40lbs at less than 500 bucks is nice, even though the brakes and gears are only basic. The manual that it came with was hidden in the seat box. FYI on that. Since I know bikes, I put it together myself without the manual, which was easy enough. (FYI, if you have ever had to take a bike apart to pack it for an airplane trip in a bike bag, then you can assemble this without a manual no problem. You're just putting the handlebars on, adjusting the stem to true, putting the pedals on and the seat in the seat tube. Really easy.) (For reference, I ride a lot and have an expensive Canyon Spectral trail MTB and a carbon gravel bike, and then a number of cheaper bikes. I'm not a super expert, but I know what I'm doing. I bought this Juneau mainly because I wanted a fat bike to try riding in the snow in the winter and I've heard from friends that they don't really like fat biking, so I figured I'd buy a cheap one before spending 2k on a "real" one, knowing that if I like it I'll want a spare for a friend to ride anyway.) ... show more

  • Fun times in the winter
Light and fun, I changed the stem almost immediately to a shorter one that's angled slightly higher to suit my riding posture. The weight is very close to my other hard tail bike. It's been a fun winter and I finally got to ride in some snow 😁 and it handled black ice better than I ever would have thought. Eventually I'm changing the forks, the balloon like tires do absorb some bumps in the road but not like actual suspension forks though. I'm more than good with this bike and will be riding it during the warmer months too ... show more

  • Gets the job done
This is my first fat bike, so I don't really have a standard for comparison, but I'm happy enough with this. I bought it so I could ride even in snow, and with low tire pressure (~3 PSI), I can bike over about an inch or two of freshly fallen snow and more of packed snow. The assembly is easy enough if you have some familiarity with bikes, though it's exasperating that they can't be bothered to match the instructions to the actual assembly state upon delivery – for instance, it arrived with the stem already inserted into the headset and the bars loose (not attached to the stem), but the manual gave extensive instructions on how to insert the stem into the headset (irrelevant) and NO information on how to attach the bars to the stem. It was obvious enough to me, but could potentially confuse someone who's never worked on bikes at all. There were lots of other such mismatches in the instructions (e.g. irrelevant attachment instructions for the cranks). Be aware you'll need metric Allen keys, metric wrenches (or an adjustable wrench), a Schraeder-compatible pump, and a special low-pressure tire gauge (the standard one that comes with your pump probably will not work on such low pressures). The tires arrived a bit inflated (~6 PSI), so I could ride it right after assembly. The brakes and derailleurs were all set up perfectly right out of the box on mine – no need for any adjustments. I find most out-of-the-box saddles pretty uncomfortable, and honestly I found this one no worse than any other. Ditto for the grips. To me the bike feels super heavy and laborious to ride – but I'm comparing it to my carbon fiber MTB with 2-inch tires, so I guess that's just the reality of fat bikes. ... show more
