Strengths:    Stron Frame, Great in snow(best ever),great price point

Weaknesses:    front Shock , heavy rimbs,Crank

Bottom Line:   
Great for the money , works better than any Mt. Bike in mud and snow I have used; however not the best for hard trails or rocks. it does not kick-out easy but lacks in the climb, needs a stronger spring in the rear.

at about $400 or less this would have been a great buy!

And the seat stinks

Date Reviewed: June 6, 2003

Strengths:    This is a bike with very a strong frame. Very agile. I had been using it nearly 3 years now. Offering a very comfortable ride - downhill, uphill or on rough terrain.

Weaknesses:    The Crank is not strong enough. Rims a bit heavy and the front suspension needs to be upgraded.



Bottom Line:   
This is a great and fairly priced bike. At abt $600, and if you are able to upgrade some of the components, you would have a bike with great performance that can easily outperform the other more expensive ones.

Submitted by ernie a Cross Country Rider from los angeles

Date Reviewed: October 7, 2002

Strengths:    Neuman frame is solid, has some "bob" on uphill climbing but not as much as I would thought on a Mongoose. Still this aint no Santa Cruz Bullitt or Specialized Epic. Componant mix is on par with most
of this price range. As mentioned by others: STX RC crank must go!


Weaknesses:    Front fork--Manitou's worst boinger next to their Magnum series. Its like having a Jett or Judy TT. Also, you can forget putting on a bottle cage unless you like getting mud or dust all over the bottle, since the only place to put one on is below the bottom tube frame.

Bottom Line:   
Heavy, ugly framed bike with a brand stamped on it everyone who knows anything about mountain bikes stays away from. Nevertheless a good bike with the same warrantee everyone else gives out. I never had trouble with the brand, I own a SX4.3 as well. Its a good value and as a bike sitting in the shop for 2 yrs, It was a steal at this price especially with the disc upgrade. I call it a "freeride" bike--its too heavy for XC racing, but only gives a 4" travel for downhills. Disc brakes and the new rims and the 2.35 Maxxis tires really weigh it down. I dont suggest this upgrade if you like to climb steep switchbacks.

Strengths:    this frame can take a hell of a beating and keep on giveing.
Shocks pretty good but more travel would be nice


Weaknesses:    Seat could be not so hard & you feel it after a bit too. Brakes are so so for the price where the hell are the discs no fade there

Bottom Line:   
good bike lasted for me and I am killer on my bikes. No big problem & if you can destroy it on the bike you'll prob. get it for free from moongoose

Submitted by Ritchy T a Racer from Cincinnati, OH

Date Reviewed: May 14, 2001

Strengths:    Room for upgrading despite other idiotic reviews. If someone truly used the bike... it is agile, quick and very durable. Frame quality is great and very durable.

Weaknesses:    Stock is okay for novice but can be weak when reaching a more advanced level of riding.

Bottom Line:   
I must admit that Mongoose has done a great injustice to their reputation by selling junk in Kmart and Walmart. Bad PR... but I hear Specialized just doofed there dealers in 2001... so their reps are on the line, too.

Anyhow, I was fortunate enough that Dick's Sporting Goods in Cincinnati Ohio luckily had two bikes in stock in 1999 (Pro Series NX 8.1) on sale. I am one of two lucky owners of the NX 8.1. I started mountain biking at age 28 in 1999 and had my first race in the fall of Fall 2000. I am considering some races in the summer of 2001. I will never be a NORBA racer but I love to ride off-road!!!

As I mentioned, the bike is worthy of upgrading and I have done so in a period of 2 years. My initial purchase of the bike and upgrades total approx. $2500 to $2800. What the average person does not understand is that most, if not all, bike makers only make the frame... all other components are made by others. The Mongoose frame is SOLID and the rear suspension is very firm in climbs... even for a full-suspension. I'll challenge anyone on the Harbin Park climbs that I can outperform a hardtail on "THE" climb.

The bike is into its 3rd season and is still kikin' butt! I am still proud to have my mongoose and most riders can't believe that they see one that has all da trimmins'!

My advise to novice riders... don't buy becuz of the hype (Bike Brands come and go)... and also do yourself a favor by going to a bike shop to get a quality mountain bike you can grow into... I happened to be fortunate with my purchase and also had lots of advise from expert riders that I have met over the years.

Strengths:    decent rear suspension, the best front suspension
tracks good, durable, good feel, agile and quick


Weaknesses:    cheap drivetrain, flexy bars and cranks, cheap rims, brakes
heavy


Bottom Line:   
actualy this is the 98 model.
practicualy the same thing.

This was my first full suspension bike.
i am now 16
the indy fork in came with was cheap. and i blew the rear shock

This bike the way it is set up now is a very good free ride bike. 5' in front, 4' in back. it weighs 33 pounds now

it is alright at climbing, doesn't bob much, decends real good, tracks real good, stays on the ground. very good jumper
i have done a lot of abuse to it and the frame is still in great condition.
can go down any decent goes where u want it to

i completly destroyed the stock bars and wheelset so i got new ones.

Now that i got the new stab primo, i ride it a lot less
duh!

the way it comes, i wouldn't buy it unless u are deciding to upgrade. it is a terrible cross country though.

i raced it downhill for 2 years and did fine
but now it just aint good enough for that

i would give it 3 chilis how it comes stock.

Strengths:    An excellent bike for the price. The kinetics and frame geometry are good.An excellent wheel set fo the price, Looks the part. Rear Suspension is easily upgradable. I love the frame! I also like the plentiful rear suspension adjustability. A solid,tough bike!

Weaknesses:    You will need to up grade the Pedals ( Mine snapped when as a result of a crash-cheap plastic ones), front for struggles for consistant and full rebound, but is still good, I weigh around 100kg. Rear Coil lacks durability(maybe becuas I am Heavy)

Bottom Line:   
The the price that you pay for this bike you cant go wrong. I have friends that have paid more for their Gt's,marins and Giants, but the extra money I saved i have used to upgrade my bike and as a result performs better tan theres. This bike will never let you down ( apart from the cheap pedals) and is an excellent choice for the weekend warrior or upgrade it to race.
