Strengths:    Solid frame, decent seat, wheels, brakes, crank and inexpensive.

Weaknesses:    Everything else.

Bottom Line:   
I bought this in about 2006. It seems to have a very short wheelbase because I cannot ride it no hands. I replaced my stolen Trek 6000 which I liked a lot more. I only get about a few midrange gears now but I have put it through some moderate tests.

Bottom Line: I wouldn't buy it again unless I was going to upgrade almost everything! Suck.

Strengths:    The frame and upgrade possibilities

Weaknesses:    The stock Bontrager stem is one of the ugliest things I have ever seen, lol (I have 4 in my garage from various Trek/ Gary Fisher bikes)

Bottom Line:   
Bikes prices have gotten out of control yet you get low end components (Shimano Acer, Alivio, Suntour fork). The older Treks are a dime a dozen and take a beating. Love the frame. Mostly use the 4900 for local XC.

Date Reviewed: December 31, 2008

Strengths:    Strong but light frame, good base components, not the best, but for the money, they are good. If you use this for more than just Saturday laps around the loose-over-hard trails, you'll probably replace the majority of the stuff.

Weaknesses:    Drivetrain, again, good for the money, but not the greatest, kind of weak.

Bottom Line:   
I bought this bike excpecting to change out the majority of the components. It was on sale, an so I figured it would be cheaper to buy this and upgrade pieces, rathr than buy a higher model that would be more xpensive in the long run.

I ride intermediate trails, and this bike has taken a beating. When I first switched to clipless, this bike took more spills than a two year olds juice box. It's held up incredibly well. The stock Judy 1 forks were poopoo, but they were switched out soon after purchasing. The Bontrager Crowbar handlebars also developed a weird crack after a couple months, must have been faulty in some way. Other bits and pieces need replacing if you are planning on putting it to real good use.

If you are just starting out, this is a nice beginner's bike; stock. If you can find it cheap, like I did, and plan on upgrades anyway, it's a great bike for intermediate riders, or anyone who still has a soft-spot for hard-tails. The core of it is outstanding. I've had my huevos busted a couple of times for riding it, but I still think it's great, lots of fun, light, holds up really well and I can do anything that my friends can do that my personal skills allow.

Strengths:    Well.. I have had this bike for 4 years now, and I am just now switching out the drivetrain. Yes, it is weak, but it has taken a beating and would have kept ticking for a bit yet..

The Frame is like Hercules


Weaknesses:    Drivetrain, seat (a minor thing), Fork

Bottom Line:   
This was a great progression bike.. and it's super tough too. (It fell off of my boyfriends trunk-car-rack going about 80MPH and all I had was a bent wheen and a broken brake lever)

This was my first "mountian bike" and I built it to my liking over these past couple of years. I have progresed right along side my bike, and I am able to race on this.

Maybe it's me being sentimental, or maybe its my awesome bike, but I love it!

I really cant complain as this bike has never let me down, it rides like a champ and has never left me out to dry.

Just remember, you are not out buying a top of the line bike, I think you get the best bang for your buck here.
A+++

Submitted by Tim a Cross Country Rider from Logan, UT

Date Reviewed: April 3, 2008

Strengths:    Frame is strong, light, and durable. Its a worthy XC frame at about 4 lbs, but strong enough to DJ or make an AM HT, if you want. This 200lb rider put alot of hard miles and falls learning to ride on this bike and it has lasted throng it all. Seems like it would fit up to a 2.5" tire on the rear. Basic components like the stem, handlbars, shifters, and brakes have worked well for me and lasted. The bike climbs so well that I was able to get away with using 90-130mm adjustable fork, and this let the bike descend lot better too.

Weaknesses:    The stock crank and wheelset are junk. Broke both within 6 months. Stock saddle is so horrible that you will want to sit on the bare post. I didn't like the fork either, its a pig at 5+ lbs for only 80mm travel. Which brings up the main problem with this bike as stock. The frame is pretty light, but almost all the components are super heavy and not too strong either.

Bottom Line:   
Basically a Good frame with some basic components that might be worth keeping. The rest is suspect. Worth upgrading as you go and you can keep the frame long term. I have a 5" FS trail bike and I am keeping this for commuting, urban riding, and riding buff single track after work. Can be built up as a 23lb XC bike, a 21lb SS, a solid 30lb AM hardtail, or DJ bike.

The frame gets a 5 for value and a 5 overall. The Rest of the bike more like 3 for value and 3 overall. So I am making it 4 and 4.

Date Reviewed: January 19, 2008

Strengths:    the frame. including the rockshox fork. these are/were solid. I have put this frame thru abuse, including dropping it from my bike carrier ON THE FREEWAY! it held up.

Weaknesses:    the components all of them- specially the wank.. i mean crank. this thing bent so quickly after a few descents.. i mean it took a pounding but doesn't hold up. the brakes - what a joke. CHANGE them! they don't work! I moved onto Shimano Deores (not so expensive and good fit) first which were great. and then onto cane creek curves - solid v-brake! The bars and stem and headset were weak. they didnt' go bad or bend, they just vibrated way too much on the trail. Moved onto carbon and magnesium Easton parts. much better damping on these. What else: rims - not so nice but sturdy. they hold on big hits, but have to be trued after every ride. figure that. I changed them too.

Bottom Line:   
a Very strong hardtail bike for a beginner in the MTB arena. I recommend it as a starter HT. as you progress, move onto high end bikes, it will save you the hassle of changing compnonents - and as you progress in trail MTB riding, you WILL change components on this bike. However, if you want to keep a solid hardtail bike with the better components on it, this is ur bike. I have another AM Fisher and am saving for my DH Maverick. But i'm definitely keeping this one for fast trail shredding. And yes, it is still an 8speed. What?! your lucky I didn't make a single speed! (but I dont' live in Northern cali now do i?) Its a fun bike and you'll be suprised (as others will be) when you can keep up on a trail with this low-end starter bike.

Bike Setup:   now: the bike has evolved and is a better machine. it sits on Mavic XC717 rims with DT DH spokes and Shimano XTR hubs. Panaracer Fire 26s tires. Shimano XTR shifters using Cane Creek curve 3 v-brakes and Aztec/Delta cables. The crank is a high end Truvativ Stylo HNC (carbon) with a GXP bb (bottom bracket). Sram XO Front derailleur & X9 RD, and Sram PG ocho speed casssette - keepin it OG. Easton has provided monkey riser bars carbon, mag ec70 stem, and seatpost. the headset was upgraded to a Crane Creek version. And now to my favourite part of the bike, the fork. The stock Rock Shox worked well. I just switched it for a larger 100mm FOX F100X terralogic. This has made a hug difference on the trail. Now put a fork in it and call it done..

Strengths:    This bike is amazing as both a tough trail bike and a commuter bike riding to classes and around town. Great Shimano components, I LOVE the shifters. Solid Deore derailleur in the rear, decent stock Bontrager tires, great brakes, and a frame with very simple and lightweight construction make an ideal bike for many uses.

Weaknesses:    I have never felt any significant difference using the "adjustable" suspension on the fork. The cranks snap crackle and pop more than a box of Rice Crispies. Get rid of the stock pedals.

Bottom Line:   
After riding this bike for several years I know that it can take all sorts of abuse from very technical downhill rides. Even so, that's not what it's meant for. This Trek really shines as a great XC bike. It climbs GREAT and can still take a beating from very fast descents. After years of use, it just takes simple routine maintenance to keep this bike in good shape-- new chain every now and then, new brakes when necessary, and a chain lube twice a month. This bike is perfect for a college student like me who loves to get out in the mountains but doesn't have the money to buy a downhill bike for the weekends. 5 Flamin' Chilis for value!!! Trek, you NAILED this one!!

Strengths:    Great looks, strong, light frame, Shimano Deore rear derailleur, disk brakes, Bontrager wheels

Weaknesses:    A bit heavy at 28lbs(OK, for full suspension), pedals

Bottom Line:   
Great all-around XC bike, for weekend warrior. Fast on the straights, with excellent climbing geometry. Upgrade to clipless pedals, for best results. Stock shock is NOT designed for anything more than 1ft drops. Keep the bike well-oiled, clean, and the drivetrain tuned-up, and this bike will not dissappoint. A real mountain bike at a real price!

Strengths:    Durable as hell. I've beat the sh*t out of this bike many time, neglected some maintenance, and ridden hard for years. A good component/drivetrain cleaning and it's good as new. You get a lot for what you pay for.

Weaknesses:    Heavy. It's like a pig compared to even mid-level bikes. The stock components (brakes, rear deraileur, etc) require constant adjustments and they kinda suck.

Bottom Line:   
With a few small upgrades of the brakes and rear deraileur (possibly front as well), it becomes a competent XC bike for novices, and it even works decent for intermediate riders (with upgraded components). I know Trek doesn't make this bike anymore, so a comparable version would be the 6000 I believe.

My favorite feature is that I constantly ride hard and beat the hell out of this bike and it keeps coming back for more!

Date Reviewed: February 7, 2007

Strengths:    To start off it has a great looking frame, Good rear derailleur (if you use it properly), Disk Brakes!, has a nice feel to it when you ride, durable.

Weaknesses:    Seat is kinda stiff but you start to like it after a while (if not its not that much to replace), The fork isn't the best around but it hasn't broken on me or anything so it does its job

Bottom Line:   
Great brike for the price. If your a weekend warrior who goes riding about 2days a week then this is a good bike for you. Its very durable, ive crashed it tons of times, landed on rock roots you name it and nothing has broken (except the reflectors, lol). I would recomend putting in clipless pedals if you wanna improve your riding efficiency and power. Sometimes the brakes get loose but they are really easy to re tighten, much easier than v-brakes. This bike i must confess is acutally not mine, my school rents them out for free, but i usually ride it about 3-4 days a week for the past 6 months. And when I'm not riding it other people are so you can imagine it gets allot of use and abuse, and with all that everything still functions fine. The rear derailleur ghost shifts sometimes and has problems shifting once in a while but that is because people who don't know how to shift have messed it up. Its an all around good bike and i highly recommend it unless you plan on doing some more serious or long term riding. But if mountain biking is something you just do for fun and aren't crazy about high performance you'll be very pleased with this bike. Although it doesn't ride like a $900 - $1100 bike, its not far behind (especially if you add clipless pedals).

Note: If your reading this you might know that they don't make it for 2007 anymore, but they have basically uprgaded it to the 6000 level which has much improvements over the 4900 and is still in the same price range, mabye 30 bucks more, i recommend going for that one if you can't find a 4900 still around for sale.
