    I have been searching for a high-quality bike designed for kids, and unfortunately, many of the large adult bike brands seem to put most of their attention into adult bikes and not the kid bikes. That is why I am so happy I found Forth Bikes. These kids’ bikes are beautifully designed with fantastic components. My son loves the bike, and it will allow him to venture into the wonderful world of mountain biking!
