Compared to a full-suspension mountain bike, a hardtail is better suited to several situations, such as riding to class, dirt jumping, riding on smoother trails, or just cruising around the neighborhood. Combining the perfect blend of hardtail performance with rugged utility, the Response Sport--which shares the same frame and several of the components of the pricier Response Comp--is equipped with an aluminum all-mountain hardtail Response trail frame with a strongbox top tube, a SR Suntour XCM suspension fork, eight-speed Rapidfire trigger shifters, Kenda Klaw XT tires, and a DB All-Mountain saddle. The Response Sport also offers several upgrades from the base-model Response, including a SR Suntour SCT crank set with replaceable chain rings, Tektro Novela 6-inch disc brakes, and Weinmann doublewall rims.

The bike is a great value. Made of 6061 Aluminum, it is both stronger and lighter than bikes made 10 or 15 years ago. The shifting group on the bike is entry level but more than sufficient for this level of bike. The brakes are wonderful, and the tires, although heavy, are quite acceptable. The front shock is pretty much crap but shouldn't cause you trouble (i.e. it is unlikely to break), only extra effort. Overall, though, it is hard to find as much bike as this at this price level. The big brand names cannot touch this bike at this price.
So, should you buy it?
To answer this question, you have to ask yourself, "What do I want out of riding?" There are many valid answers to this question, so think about it. Are you planning on riding the local gravel trail in town? Are you planning on short trips around with the kids? Would you prefer to ride actually two-track trails with roots, stumps, rocks and sand? Or are you looking to do distance riding with friends?
Answering these questions honestly will go a long way toward deciding whether this bike is for you. So what is this bike best used for? This bike is almost exclusively for riding gravel trails around town with the occasional off-road or two track. It is NOT meant for riding around town and definitely not for distance riding. Similarly, it shouldn't be bought if you plan on riding technical trails with drops and steep climbs.
Let me back up my unfounded statements. Gravel trails are easy to ride and you could easily get away with a touring bike (defined as thinner tires and a more upright, laid back riding style). But every so often, you will hit a patch that could puncture your tire and/or tube on a touring bike. The Kenda tires and soft shock will keep that from happening on the Response. Similarly, the low gear ratios on this bike will make riding up hills much easier, as long as the path is not too rough. If you are doing steep inclines on a bumpy road, the crap shock that comes with this bike will feel like a pogo-stick, causing the front tire to lose grip with the road/trail. This will most likely end with you walking the bike up. But in well maintained trails, you should excel.
If you are riding around town, you'll see lots of surburbanites riding their Treks and Specialized mountain bikes. You would fit right in with this bike. However, you would be better served by a touring (sometimes called "hybrid") bike. Something like this: Diamondback Edgewood Men's Comfort Hybrid Bike (700c Wheels)
I know, it is not as cool looking. And looks should factor in since you want to feel good when riding around town. But that less cool looking will translate into higher speeds, less effort, and more comfort. If, on the other hand, you are planning on riding technical trails, you will need more gear. You could buy a better front fork (at a minimum, something like this: RockShox Tora Coil 302 U-Turn Fork (Black Pl Rim/Disc, 85-130) ) but really, you'd be better off spending more on a lighter, more complete bike. You should expect to spend at least 50% more on an entry level bike for more serious downhill and technical trails. If you are over 5'10", you might even consider a 29-inch mountain bike.
Finally, if you want to do distance riding, the bike is wholly inappropriate. The riding stance and the tire thickness would make this bike (or any mountain bike) a poor choice for anyone other than the most fit athlete out there.
In summary, this is a GREAT value bike, oodles better than anything you find at your local discount market. Moreover, Giant, Specialized, and Trek cannot touch this price point and, although you must compromise on weight, front fork, and grouping, you will get a whole lot of bike for a low price.
By the way, yes, I both own and ride this bike, along with my Giant TCX Crossbike.
UPDATE: The day I wrote my review, the bike was on sale. Now that the price is back up, I would knock off a 1/2 a star, since the value is diminished. I'm not saying it's not worth Amazon's price, only that if I were you, I would consider waiting for a sale.

The Diamondback Response Sport is a very good value in a hardtail mountain bike as you are getting a relatively high end frame design with mid range components. The modified top tube design is a strengthen design borrowed from higher end Diamondback models and similar to some Specialized bikes.
The only catch is that the shift levers and front caliper are not up to the same quality as the rest of the package. The platform pedals are OK for around town and park trails, but you may want to upgrade them for serious single track riding.
I combined this with a top quality suspension seatpost which I find to be the optimum combination of lighter weight and control with some softening of the roughest bumps. The Diamondback site and some retailers have a more complete description of which frame size is most appropriate for your height. The advantage of buying from Amazon is that you can readily get XS, S or XL frame sizes rather than having to settle for Medium or Large at a local shop or sporting goods box store.
The bike arrives mostly assembled, but plan to spend a full Saturday afternoon to correctly reset the derailer travel limits and align the front caliper if you do not take it to a local shop for a professional tune up.

I just got my D-Back Response Sport 2 days ago. Package arrived 3 days from order using the free shipping, Way to go Amazon!.
Bike was well packaged and was easy to assemble, however the Hayes brake instructions could have been better. Still not that hard to figure out. Only complaint is that the bike came with a Shimano Tourney front derailer and not the listed derailer. It works fine and shifts well so I'm not really dissatisfied. It also came with metal D-back pedals and not the resin pedals some people have replied on before. I'm 270 lbs. and wanted a strong bike, this appears to be just that. Time will tell and I will post follow ups as time goes by.
Seat was a little on the hard side for my big bottom side so i replaced it with a Sunlite Cloud 9 seat that has been a big improvement.
*Note* I got the 18" frame and it is perfect for my 5'10" size.
