About Mongoose
Founded in 1974 in a Southern California garage, Mongoose has always been an innovator. From the company's initial cast-magnesium MotoMag wheels to its current crop of BMX, mountain, and pavement bikes, the Mongoose name has been synonymous with bicycle performance. Mongoose builds specifically for riders, which is why the company's BMX designers aren't wasting time watching reruns on ESPN2. Instead, they're constantly testing their new designs at the park, on the track, and on the hill. This continuous experimentation is what drives Mongoose to cook up things like the Front Porch head tube, which lets you fine-tune the handling on Black Diamond series mountain bikes, or Freedrive suspension technology, which eliminates pedal bob and provides a super-efficient full suspension. Mongoose bikes don't just push the limits; they set new ones.

By Trevor K. Thomas on June 8, 2008
Got this bike primarily for my commute to work. Yes, even though a mountain bike isn't the most efficient bike for the roads, I wanted something that I could get a little rough with. So far I'm not disappointed at all. The gears did need a little tweaking but after that it's been smooth sailing. The Shimano derailleurs are nice, the dual suspension is terrific (my first bike with any suspension). With probably a few upgrades to components this could be a hardcore bike. For this price it definately competes with $1000 bikes.

Bought this bike on sale for 240 + tax.

First of all it is a good quality bike.

I ride each other day to work (6 mile or 25 minutes cycling one way...) for 2 months.
With my height 6ft this bike is a little bit small for me... maybe for person below 6ft it would be just fine.
It provides nice comfortable ride. It is not super fast. It could be lighter.

Overall it is OK... My next bike would be a road bike :)

After getting into singletrack riding I purchased this bike at a thrift store to replace the department store bike that started falling apart on the trails. While there are certainly better more trail specific bikes out there I can't complain much about this one. When I got this bike it had 2.1 inch tires which work great for the sand often on the trails (though not sure if it comes with these or if someone added them). Two or three inches of travel on both the front and rear shocks give it enough cushion for the two or three foot drops here in florida though I would bottom it out at any drop three feet or more. Overall a durable frame with responsive shifters and decent handling. My two problems with the bike would be the front disk brake and grips are two short. The disc brake is terribly weak but after some adjustments it can be adjusted for adequate stopping power provided you aren't riding DH or anything. Last thing is that the grips on the bars are so short you have to also put your hands on the shifters so if you hit roots or drops accidental gear shifts is easy to make. In conclusion this is a great entry level bike with a few fixable problems.

Update: Had to drop it down to four stars. Hit a jump today and the rear derailleur snapped off the frame. Still a great bike but some upgrades are needed if you plan to do more aggressive trail riding.

I put new pedals on it and it rides smooth, I also bought the gel seat from the same brand. Rides confortably and is well built and stable. It needed work on the shifts and gears but I took it to the LBS and it's smooth now. I also added a cheap kickstand. I think the frame is a bit on the average weight but not too much. I liked the color and the rear suspension is responsive, you may be able to pull some tricks even on flat terrain. UPDATE: I took it to the woods bike trail and it took no damage, I had fun, trigger gears are pretty responsive. Tip: always wear mosquito repellent when adventuring to the woods.

Awesome bike for a good price! It looks great and you would recognize your yellow bike from miles away. There is no kickstand but it is not a big deal. It takes 5 min from unpacking to complete assembly if you have an allen wrench at home. I wish an allen wrench was included since it's the only tool necessary to tighten the handle bar.

It would be nice if there was some consistancy in the product description. One paragraph says it has a front disk brake, but the next says that the front and back are both v-brakes. Then one paragraph says that it's a 21-speed bike and the next a 24-speed. For the record, it is a 24-speed bike that has front and back v-brakes. At least mine did. If anybody's bike came with that front disk brake, please let me know.

About that front derailleur: I see that a few reviewers here were having trouble with it too. I first adjusted it myself, but since I couldn't get it exact, I thought I was doing something wrong. After taking it to a bike shop and still having the same shifting problems, I know it wasn't me. That front derailleur is extremely tight and hard to work with. You have to set it extremely tight just to get anywhere.

The Shocks are great and I can definitely feel the difference compared to other bikes I had. I do like this bike, and I want to rate it higher, but that issue with the front derailleur hurts the feelings a lot. It makes the bike risky to use at higher gears since there is rub and the shifting is iffy. If I figure out the issue with that, I'd rate this bike higher.

*New (7/22/12)So now there's a new problem with this bike. The bolt that holds the crankshaft in place seems to be missing. Because of that, there's some play between the parts and that could be the reason why some people had the issue of the chain hopping off the track at higher gears. I'm going to see if there's anything that can be done about that. I really like the bike but there have been a lot of problems....

I purchased this bike on August 30, 2011. It didn't last a year.

I assembled it and took it to a bike shop to get a tune up. I was informed that both wheels were not true and the components were not of the best quality.

I always had trouble with shifting(even after taking it to two different bike shops for tune ups)either it would skip a gear or the chain would pop out.

I mainly used it as a road bike, but the few times I took it off road on a trail the chain always popped and as I would peddle I could feel it slipping.

On one occasion the chain popped off and got tangled in the peddle. As I was down peddling and going up hill I couldn't stop resulting in the front derailleur getting yanked by the chain and completely warped(I was going pretty hard while going up the hill on a dirt trail)

I decided to give up on this bike as my main road/mountain bike. I will fix it and keep it as a road bike, but it will definitively not be seeing any trails.
