  • Do not buy!
Color: Matte Blue
My 9yr old son picked this out, and I wish I had paid attention to the reviews before ordering. This bike is garbage! It is very poorly made. The front fork was welded crooked where the wheel axle is supposed to sit. I didn't realize it at first and just wondered why it was so hard to get the wheel on, then noticed the brake was rubbing on one side and the wheel went to the left when the handle bars and upper fork were straight forward. The entire bike is just unbalanced, and the rubber tires are so thin and flimsy, they look like one tiny rock could shred them on the first ride. The bike is already repacked and ready to be shipped back, less than 24 hours after it was received. ... show more

  • Great sturdy bike, lots of fun
Color: Matte Blue
The bike is solid, no loose bolts or screws, and the frame is very well engineered. Shocks work great, gears change easily, and it is overall very light weight.

  • Underwhelming quality
Color: Matte grey
The bike is way too small to accommodate an adult, is far too fragile to be used as a mountain bike, and lacks a gear shift with enough resistance to make riding challenging, as it is, the highest resistance gears feel as hard to pedal as walking. I would not recommend this bike unless it was for a child with little muscle mass planning on riding on commercial paths. ... show more

  • Missing parts, dificult to put together
Color: Matte Blue
First off, it looks like a really strong nice bike but we are having 2 issues with this bike. First, the piece that keeps the front bars from spreading to much that attaches to the front tire was missing. 2nd the bolt on the front tire was put on to tight. I will have to take the bike to a shop now and pay to have it fixed. ... show more

  • Review of Costic 26" Moutain Adult/Youth Bike
Color: Matte Blue
Received the bike in one large box about a week ago. Costic Brand 26" Mountain Adult/Youth. The cost was about $200 and it took about 10 days to receive it. It is a Beautiful color Teal-Blue and Black with easy on/off bar. Seat feels a little firm so maybe a little more gel for comfort while riding. Instructions for assembly were easy to follow and took about 30-40 minutes. Due to bad weather no one has had the chance to ride the bike as of today. Planning to ride as soon as possible. It will be ridden for recreation and exercise and will mostly ride on road/pavement. As I get use to how the bike rides, the braking system and how to change gears it will become possible for me to ride off road. ... show more

  • Clearly Preopened
Color: Matte grey
This product had clearly been opened by someone else. It was missing parts and other parts were already broken when I got it. Considering whether to return it. I was able to put it together because my son was excited to ride it for his birthday. But ultimately it's disappointing to buy a new product and find it has already been picked through. ... show more

  • Poorly made
Color: Matte grey
Bike functions correctly except my handle bars came off while riding and the initial parts did not fit. The manufacturer did sent the correct items but overall I’d go with a different brand

  • Good Bike
Color: Matte grey
It's a good quality bike that's easy to ride, aside from the seat that it comes with I have no complaints whatsoever. I use it all the time, the price makes it all the better as bikes are so expensive and this one offers a great experience for the price.
