Once upon a time, bike options for kids were limited to banana seats and BMX. Thankfully, now whether they're 10 months old or a teen, there's a bike designed for exactly what they want to do (even if it's just scooting across carpet). But just as these bikes come in all shapes and sizes, so do kids. That means your top priority when shopping — even beyond frame color — is finding a bike that fits. Unlike adult frames, children's bike sizing goes by wheel height. Your local bike shop can fit your kiddo on a new rig, but you can also consult this handy chart. Here are our top picks to get kids of any size and age riding.
