Sensational bike! Bravo Diamondback
This bike is sensational from looks to bang for the buck performance. In person, it's absolutely stunning but more importantly it rides like a much more expensive bike. I can't believe how light it is. I'm 6'0" tall and the medium frame suits me quite well. I had REI switch out the stock seat (it's quite hard, thin and uncomfortable) for a split gel one and I signed up for the $20 rewards program so after tax I was well over $800 and I still feel like a got a great deal on a bike that will last many years. The tires are fabulous too btw.
Hard charging Diamondback Overdrive
Lite, maneuverable, BMW of bikes. This bikes wants to go. My son loves it, so he's adopted it as his own.
Great entry level mountain bike!
I bought this bike after numerous hours of research. This bike has quality components for a great price. I have been on a couple of rides it shifts great, cruises nice, has great traction going down steep dirt hills, the hydraulic brakes are fabulous and it jumps like a dream.
Great MTB
I have been using this bike for a month. It handles great and I am very happy with the performance.
Love this bike
I've had this bike for 2 months now and it has gotten a lot of use. The bigger tires roll right over roots and rocks and the brakes are excellent. I'm 6'0 215lbs and the Large size is a good fit. The stock saddle is a bit thin so I bought a more padded one to replace it with. Besides the saddle, I love everything about this bike and highly recommend it for someone looking for a quality hardtail at a good price.
Really responsive
I've had this bike 4 months now and I have no complaints. The braking is amazing (Make sure you align the discs and pads so they are not rubbing and making noise while you're not using them) the shifting is smooth and the tires have good grip. The fork is still a spring but still very good as it takes what I can throw at it. I've taken it on a technical trail and handles incredibly. The seat is not comfortable but you can get some MTB padded shorts/underwear for that. I definitely recommend it.
Frekin Love it.
This bike is awesome, definalty can take a beating. Had it for about a year. Handles very well, easy to maintain. The seat isn't as comfortable I I would like, but manageable.
