    • WORTHLESS WARRANTY!

Review Image by gertrude carfi gertrude carfi
I like the bike but Mongoose customer service and warranty are the worst. I had a problem with the freehub (part that makes the clicking sound you hear in the rear wheel) the freehub started making a loud noise and slipped every once in a while so I called Mongoose to get a replacement part/new freehub as the bike was only two months old at the time and under warranty, well long story short... Mongoose doesn't stock the freehub part and they told me they can't get one but they can replace the bike or I could take the bike to one of my local bike shops and have it repaired and they will reimburse me the cost to fix the bike minus any labor, what a joke. I called all my local bike shops within reasonable driving distance, and they all told me they don't carry this type of freehub because it is an outdated old style freehub from the 80's and a cheap China part, they all said modern bikes that they sell don't use this type of freehub and it would be next to impossible to find the part. That said... I did some research and went on amazon and eBay but couldn't find this type of freehub anywhere, there was one freehub that looked similar to mine but you had to order from China and it may not be the right one anyway, so there is no way for me or the bike shops to get one, how could we get one if the manufacturer/Mongoose can't get one? Well this leaves me with the option of returning my bike for a new one which I shouldn't have to do, I told mongoose if you are willing to replace the whole bike then why don't you just take the back wheel assembly off the bike you are willing to send me, send it to me and I will send you back my broken back wheel, PROBLEM SOLVED, no they can't do that, WHAT A JOKE. I told Mongoose I shouldn't have to send my bike back to you because you don't stock parts for your bikes under warranty, I have installed many upgraded parts on the bike and I shouldn't have to disassemble the whole bike and make it stock again because you guys cannot honor your warranty and send me a $25 part, I would have to take apart the whole bike and remove my upgraded parts which include: new...tires, larger disc brake rotors (front and rear) original rear brake rotor was warped out of the box, hydraulic brake system (front and rear) suspension seat post and new seat, front suspension fork, grips, crank gear (original one came bent out of the box) Cateye odometer, decals on the frame, new pedals and fenders, Like I said I shouldn't have to disassemble my bike and make it stock again because Mongoose doesn't carry/stock parts for their bikes under warranty. I also sent Mongoose pics of the part I needed when I first called them to make sure they get me the right part, they said they had the part in stock so I told them to make sure it's the right part before you ship it out to me, so the lady I spoke with told me she was going to double check and show my pics of the freehub part to one of their tech guys to confirm it is the right part before she ships it out, so I waited on the phone for a few minutes and she came back and said... yep it's the right part you need, well when I received the part I started laughing because she sent me the wrong part, she sent me the cassette gears on the rear wheel, I don't know how anyone can make that mistake with a pic of the part in their hand, this more than proves that they literally know nothing about the bikes they are selling and this is not the first time this has happened, my brother needed parts from Mongoose once and he also sent them pics of the part he needed and they sent him the wrong parts as well, after reading some of the other reviews on here it looks like this is a common problem, Mongoose needs to hire people with better technical knowledge of bikes. Bottom line... I shouldn't have to ship my bike back to Mongoose (and have to remove all my upgraded and personalized parts) because they don't stock parts for their bikes under warranty, all I need is a $25 freehub part to be replaced, (THAT MONGOOSE AND NOBODY CAN GET) if you bought a new car and the battery went dead you don't replace the car they replace the battery. I really don't want to take a chance on getting another broken bike from Mongoose because every bike me, my family and friends bought from Mongoose had something wrong with it as did the many people who bought this bike here as per reviews, I just want to fix the bike I have. SHAME ON MONGOOSE FOR NOT HONORING THEIR WARRANTY AND FOR NOT STOCKING PARTS FOR THEIR CUSTOMERS WHEN THEY NEED THEM TO FIX THEIR BIKES UNDER WARRANTY. First pic is of the back wheel so you can see the part I need replaced in the center of the wheel. (FREEHUB) Second pic is of the bike with the many upgraded parts. ... show more

    • 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

    • Impressive bike for the sale price!
Bought this bike to get some exercise and it is great for that! One of the first things I did was disassemble the bottom bracket to check for filings. Mine had none and was nicely greased for sealed bearings. My bike came almost dialed in out of the box. My back brake needed a quick alignment my rear derailer was adjusted well just needed the cable tensioned up a bit to hit the gears smoothly. The front derailer needed the high and low screws adjusted but that was easy. I did replace the pedals because I don’t like plastic pedals, I got some for about $17 here on Amazon. I increased the tire pressure from 10 to 15 pounds because I ride mainly on roads. A lot of people complain about the seat but I find it comfortable. I road bmx bikes all through my youth so I got used to uncomfortable seats I guess. I would say don’t order a new seat for the bike until you test it on a couple rides, like I said, I like the seat. I also took off most of the stickers, I thought it made the frame look cluttered and cheap. Speaking of the frame, this bike is 6061 aluminum and very light, I couldn’t imagine a steel frame on this bike, it would weight a ton. I hop this review helps you decide on yea or nea for purchasing this bike. I did get it for a good price on sale so I’m very partial towards this bike. ... show more
