    • Nice bike for a good price
Color: Red Size: 24''
Review Image by MelissaK MelissaK
My daughter really wanted a red bike but the only one they had at Walmart was fitted more for a boy and she had a hard time reaching the handle bars. I went out on a limb and ordered this one. My husband assembled it just fine (he is good at that kind of stuff) and it looks really nice. My daughter was happy to get it for Christmas and seems to fit her well. She hasn’t had a chance to ride it yet so I will have to write an update once the snow melts, but it seems to be a really nice bike. ... show more

    • Looks High-end. Impressed.
Color: Black Size: 24''
I bought this for my 11 year-old‘s birthday. It looks like a high-quality bike from one of those expensive stores. She gets lots of compliments on it. She enjoys riding it a lot. She’s 5 foot and it’s a good fit for her. She loves black, so the style is perfect. I took it to a nearby bike store to have it assembled so it would be done right so I can’t comment on if it was easy to assemble. ... show more

21-speed bike is perfect for an 11-year-old—sturdy and sleek-looking. It was pretty easy to put together, even though the instructions weren’t the best, I managed to figure it out. Overall, it’s a beautiful bike for the price and offers great quality and style. Highly recommend!

    • Good mountain/road bike
Color: Black Size: 24''
So initially I purchased for a gift to my nephew but my brother had already purchased him a bike so I ended up keeping it. The bike itself is very sturdy and of high quality material. Very easy to assemble and tools are also provided to help in assembling. When I inflated the tires I noticed the back inner tube would not hold air and I contact CSR which were no help because they pretty much told me to buy a new one and they’d reimburse but I never got the moneys back that I spent on a new inner tube. It looks great and feels great. The breaks needed to be adjusted but that’s common from an in box bike. Functional and fit for most young adults under 6’. All parts are provided in the shipping box. ... show more

    • Great purchase worth 10 stars
Color: Black Size: 24''
i could not be more pleased with this bike usually a bike with a aluminum frame and the custom features this bike has cost over a thousand dollars. The price I paid was fantastic. I gave it to my grandson for christmas. It only took his dad and me 20 minutes to put it together. Your manual was great. Explaining the gears at the end was a big help, watching my grandson ride his bike, you made a young boy and me very happy this ciahristmas. I am sure to recieve questions on where I bought this bike and will be more than happy to provide a very positive recommendation. Thank you ... show more
