Best Kids Mountain Bikes: Our Top Picks

Don’t think that because a bike frame is too big now, it doesn’t matter as they will eventually grow into it. That might well be true but don’t overwhelm your child by purchasing something for them that would scare them.

It is all about the fun factor and getting them involved in enjoying mountain biking, so think carefully about what you invest in at that moment. With that said, we’ve hand-picked three of what we believe are excellent recommendations.

Additionally, as it is fitted with an HL Zoom 40mm travel fork, it soaks up the stress and strains of riding over rocks and roots for a smooth and comfortable cycling experience.

With robust and reliable brakes and a forked suspension system, it’s equally as comfortable if they’re hitting a back trail as it is the sidewalks and streets of your neighborhood. It’s suitable for girls with age ranging from eight to 12 years old or up to a height of 62 inches.
