Review Image by Cj C.
I was skeptical buying a Mongoose as I wanted to upgrade from my squeeky walmart bike and hit the trails a little harder. I'm coming from a $250 bike but Holy cow this Mongoose is amazing. I was able to keep up with riders on Specialized and Trek bikes and even tho this is a hardtail it gives me alot more confidence. I was amazed at how effortlessly I could climb slopes I had to walk up on my old bike. I didn't even have to stand up, I just dropped to the lower bottom bracket gear and fly up hills. The front fork seems ok, it does a noticeable job at dampening roots and drops and I like the locking feature. The only thing I'd change has to be the grips, after maybe 15 minutes my palms hurt and they hurt the entire 2 hour ride. But I still had a very good time. Love this bike ... show more

    • Great value
I had just bought a fat tire mountain bike from Mongoose. It is a great bike but even after changing the tires to road tires I was only able to pedal 8.5 mph max so I decided to try another Mongoose but one designed for bike trails as well as light mountain trails. I was able to put it together very easily. I read some complaints about the handlebar stem being backwards but this is the way most bikes are shipped. All you have to do is loosen the screws on the stem and turn it 180 degrees. I am mechanically inclined so this was automatically intuitive to me. I bought the medium frame because it was 25% off but at 5'7" I was in between small and medium frame. At first I was worried about the center bar being a male but it was no problem. I quickly learned to just tilt the bike a little bit when I stop and dismount. The Expert 18 speed was good enough for bike trail riding at top gear. I love the trigger shifters. Keep in mind that although the left shifter has 3 positions you only use 2 positions on it since 2 x 9 = 18. If you have three sprockets in front gear set you will use all 3 positions. This is most likely the Trail version with 21 speeds which use 3 x 7 = 21. All 3 on front gear set and only 7 on rear set. The Comp and Sport versions of 9 and 8 speeds, respectively most likely have only 1 front sprocket so you probably only use position 1 on left trigger. My shifters worked great and needed no adjustment. I love the disc brakes as it has great stopping power. Only negative I faced is when seat was all the way down it was still a bit high for my 29" inseam. It could not go down further because the stem hit the threaded inserts from accessory mount screws. You will have to buy a kickstand as it doesn't come with one. Overall, I took it on bike trail today and was able to get up to 13 mph on level surface. It is a great bike for the value and I recommend it. ... show more

    • Poor quality for its price
Front fork doesn’t work properly, you should probably get another one for this bike. However, manufacturer answered this is “how it’s supposed to be” after I contacted them, but fork quality is very poor.

    • I think the size runs a little small
Great bike, although I did receive it with 1 flat tire. I contacted mongoose and sent me a new innertube. The derailer does need to be adjusted. Also I feel a little big for the bike and it seems like the size description isn't right but I'll end up keeping it because i do like it.but other than that is was easy to put together. I feel like this bike is to expensive for what it is. I looked at some trek marlin models in the same price range and they have better components. ... show more

    • Good bike, poor construction
I bought a Mongoose EXPERT MB. I liked the bike and it was easy to assemble (just have to turn a few screws and the peddles). Problem was that it would not shift to all gears and would not shift smooth. It would either skip in 1st or not even grab 9th gear(s). Using the tuning screws (high/low, etc) I was able to stop the chain "grapple" and the noise associated. I could get gears to shift somewhat smooth, but was unable to get 1st gear to catch at all. I tuned the opposite and could get 1st through 8 to change somewhat smooth, but could not reach 9th gear. No matter how you cut it, I got an 8 speed rather than a 9 speed that ran "clunky" in the peddles and crank. The bike is lightweight and has quick release front and back wheels. The rear chain rail does not have a clutch and everything is cable operated. Disc brakes worked awesome and were easy to tune/adjust. I would have kept the bike had all gears worked, seems as if I am not the only person with this issue. ... show more
