    Great Bike

    Customer review by Allforthedog

    5.0 stars by Allforthedog

    In my search for a 20" bike, I have noticed that the options are either crazy expensive at a bike shop, or super cheapo/fall apart types. Further, most seem to be BMX bikes and it's seems harder to actually find just a regular bike in a moderate price range. Finally, this fit our needs. My son loves the color, the graphics, the seven gears. (Note: There are seven gears; the product specs said it's a single speed bike). I love that it has quality parts and was offered at a reasonable price. Have used it every day since purchase, and it's making us happy.

    Customer review by nicole0710

    I bought this bike for my 7 year old (almost 8) son. He wanted a big boy bike like mom has. So i did a lot of research and thought this bike looked great. I ordered it online and had it shipped for free.. GREAT deal. We took it out of the box and panicked I am not that great at putting things together but I stated cutting everyone off and getting all the pieces together. It wasn't that bad. I needed to put on the seat, pedals, handle bar, and finally the front tire. Everything was a piece of cake UNTIL i got to the tire. I had to loosen the breaks which I had no idea what I was doing. It took me almost an hour to figure that out and put it all back, making sure the break was the correct tightness/looseness was a pain in the rear. It wasn't fun at all but my son is happy. I would not recommend this bike for a 12 year old its a lot smaller than I thought. Its perfect for my son. Who again is 7 years old and 49 inches tall.
