  • Nice and strong bicycle.
Easy to assemble, smooth ride. Why did you pick this product vs others?: Good brand and sturdy design, and nice blue color.

  • Terrible components
Got the bike really fast. Loved the color and had to wait for almost a month until my bike repair guy was back from vacation. Brought the bike to him to assemble. Got it put together and I took it for a spin. Brakes were horrible. I couldn't switch gears properly. He adjusted everything replaced all cables right away. Brakes then worked amazingly! He worked on my gearing for almost three hours (granted we were talking a bit) but pulled out every trick in the book. Could not figure it out. Huge disappointment. Sent back and got a refund but I'm out the cost him working on it and my time taking it apart and boxing it back up. Brought it to ups and they told me because the corner of the original box was wet they had to repack it and charged me for it. I did however get the cost of the ups back. Overall not happy with the product! ... show more

  • Best price around!!!
I found this same bike at a big name sporting goods chain store for almost double. All aluminum frame with shocks. I can’t say enough about the price this is selling for.

  • Very Good For The Price
Size: 26-Inch Wheels Color: Teal
This bike is very good for the price. After riding it daily it has been reliable and fun to ride on flat trails and marshland where I live in Hawaii. I have not taken it on any mountain areas yet so not sure how it would hold up there. The frame is solid, quite light in weight (I think aluminum) it shifts and handles well, and the disc brakes and tires are very good. The only complaints for me would be it has hard rough suspension, you will feel every bump, and a hard seat. Overall a very decent bike for the price and definitely recommended. Sweet color choices too. ... show more

Size: 24-Inch Wheels Color: Purple
This is a great value. Got it for my daughter's birthday. She's a tall 8 and is a little big but still able to ride it and will last for a while. We've purchased this brand in the past for my older boys when they were the same age. Really great bike.

  • bike damaged in shipping. cost ~$150 to replace a brand new bike tire for a brand new bike
Size: 26-Inch Wheels Color: Tan
The media could not be loaded. the rear tires axel came bent straight from the box, so bad that the bike is unsafe to ride and the de-railers miss changing gears because of it. also both sets of brakes squeak terribly. Really disappointing for a ~$350 bike to be un-usable out of the box. assembly was easy and fast, but didn't matter cuz the axel is bent beyond usability. ... show more
