    Strength:

    Solid frame with pretty good geometry for XC trails. Mechanical disc brakes and sturdy wheels. Shimano components.

    Weakness:

    It's a 7x3 speed bike, so upgrading the drive train isn't straight forward. The brakes aren't great. Stock pedals, seat, and grips are rubbish.

    The Trek Marlin 5 (2017) is actually a decent entry level bike. Sure, the components aren't great, and the fork is like a pogo stick, but I've taken it on local mountain trails and I have jumped it, went down rocky turns, crashed it a few times, and it's still working 100%. For the price $550 it is great for getting into the sport. I'm already thinking of upgrading to something twice the price, but for the money it's a great bike.

    Strength:

    highend frame with stable G2 geometry for aggressive riding.

    Weakness:

    forks and brakes suck ass, crankset and wheels are cheap and bulky

    Have had this bike for about 3 years now and have fully built it up. I beat on this bike and it holds up like a high end machine. have fallen many times and have crashed down tube first into the corner of a stone wall, leaving only a small dent. im a 5' 10" rider with a 17.5in frame and think its a bit small but i can maneuver the bike how i want and forget how small it is when descending. I use this bike mainly for XC/Trail/DJ/Aggressive street riding (use to ride bmx) . Great all around bike after a few mandatory upgrades(forks, brakes, bigger bars, DH tires)

    Strength:

    The frame is great and it hasn't failed me. The geometry is pretty good too.

    Weakness:

    The grips are horrid, the back brake never worked properly from the start so I had to go get a new rotor and pads, the shocks are rock hard and they blew out on my yesterday, and the chain stretched out in 6 months of riding and broke my back cassete and hub.

    This bike is great for its price, but it is beginner level only. After taking it out on some blues, blacks, and jump trails, this bike completely failed me. From the start I had replaced the grips, and I had to keep taking it in for various back brake problems. About 8 months after buying the bike I just got a new back rotor and pads. That fixed that problem. Two problem free rides and then my back cassete stopped engaging. I took it to a bike shop and they said my chain had gone through its life. In six moths?!
    The chain stretching ruined my back cassete and I had to replace it. Now that that that is fixed my fork is shot and it blew both seals.
    I will say that this bike is great for the price if you are a beginner, but every ride I have had on this bike something breaks.

    Strength:

    Great price, responsiveness, 29" wheels

    Weakness:

    Components could be better, mostly the rear derailleur

    I recently purchased this bike. My main uses are for commuting to work, and attaching a trailer for riding with my kid, and some light mountain biking.

    I have really been enjoying the bike. I think it is a great bike for the price point.

    I did the usual upgrades you get when you buy a new bike. Swapped out the pedals for spd's, changes the tubes to prestas, and added lizard skins to keep the goat heads from puncturing the tubes. Took off the reflectors, and of course added a saddle bag.

    The biggest cons I have found about the bike are the rear derailleur needs to be upgraded. In my experience, even with cheaper mtn. Bikes. The derailleur is usually a better quality than the front.

    I also found that the seat is too soft. I feel like I am sitting on a lazy boy couch. I will be upgrading the seat to something harder. I am not sure why others have found it to be so hard, but then again I am used to riding a road bike with an extremely stiff seat.

    Great bike, glad I bought it.

    Strength:

    Hydraulic disc brakes

    Weakness:

    Cheap pedals, some may find sea hard

    Overall great bike. It is the cheapest you can get hydraulic disc brakes. The pedals are quite cheap and some may find the seat uncomfortable (It feels great to me as the one on my old bike was WAY worse!)

    Strength:

    Hydraulic disc brakes (Marlin 6), Frame, Style, G2 Geometry

    Weakness:

    Rims (single wall), Pedals, Seat, front and rear derailleur

    2014 Trek Marlin 6 - After putting some miles on the bike and taking it on a few trails I have to say I am very please with this bike. For the price range I would say it is one of the best options if you want a new bike. A lot of the reviews on here call this a beginners bike, but I would say it is as least intermediate I take this bike on blue, and black (expert) trails every weekend and have not had any issues. That being said I am not on down hill trails with large jumps, this bike was not designed for that, and I would not recommend this bike for that type of ridding.

    Now for the bad - Even though I have not had a problem with the bike yet, I know from past experience with other bikes the single wall rims are going to fail on me. The front and rear derailleur work but they are the cheapest for a reason. Peddles are junk replace them I put MG1's on the bike for $30 and they work great. The stock seat is not comfortable.. I added a XLC suspension seat post and Zefal Journey seat and now my bike is super comfortable.

    In closing, if you are looking for a new bike and want to spend less then 600 this is a good buy. Go test it and a few others and see what fits you the best.

    Strength:

    I have the Marlin Singlespeed so it is pretty light. Also the bike came with Maxxis so the tires are awesome.

    Weakness:

    The stock Fork and the brakes

    I upgraded the Fork to a Rock Shox XC32 and love it. Its not a terribly expensive fork (only a few hundred) and rides very nicely. I also like the maxxis tires i have on it. The 29er wheels save ur butt a lot when riding to fast. I purchased it from my LBS at a very good price (379) so i got a lot of bang for my buck

    Strength:

    Great frame, strong double-wall wheels (for price), great geometry.

    Weakness:

    Brakes, fork and tires

    I have owned my 2012 Trek Marlin for about two years now. Despite the sub-par brakes and mediocre fork, it is a great bike for the money. It has handled moderate trail riding better than I had imagined with minimal problems. The frame is definitely worthy of upgrading with improved components. I think upgrading to good quality hydraulic brakes and a better fork would make this a great trail bike for the novice rider.

    Jake W a cross country fan   Weekend Warrior [Mar 12, 2014]
    Strength:

    good frame decent bars and shifters and derailers

    Weakness:

    fork and tires

    i got the 2013 model in august after riding a few of its competers mine is the 21" frame model and man it is good. While the fork is to stiff even with the preload as soft as possible it is still overly stiff. Most people complain about the brakes and while they are not the worst they are not anything to write home about ether. But the tires are almost worthless they are ok for purely street riding they are horrible in semi loose and in snow well they spin when trying to go from 18 to 20 mph downhill ya pretty bad but at least you can adapt to them. Sorry but i haven't changed anything except the grips and added Mr.toughies to the tires to prevent flats but as is for the money it is great if you can afford it this is a great bike especially if you add a better fork and tires and maybe even brakes

    Nealsen Armstrong   Cross Country Rider [Nov 21, 2013]
    Strength:

    Great color green ,Good upgradable frame and good ride geometry. But an awesome bike after you upgrade a few things.

    Weakness:

    The brakes and the fork but most bikes at this price point have this weakness.

    This is a good bike with a good alpha gold frame. I have a 2012 and I'm still riding it and having fun on the trails. But with upgrades it will be an awesome bike. The brake and the fork. On mine I upgraded the brakes first for safety. I put Avid Elixir 5 brakes and now it will stop on a dime. And recently I put a Rock Shox XC 32 Solo Air fork and 29/ 2.2 tires with a little more aggressive tread and now my Marlin rocks! The fork upgrade dropped 2 lbs off the bikes weight. But upgrades are pricey. If you cannot afford upgrades for a while keep your brake rotors clean and properly adjusted. But if you can get one upgrade save up 200$ and get some good hydraulic disc brakes. But this is a good bike with potential to be a great bike with a few upgrades.
