Kids’ mountain bikes generally have wider, knobbier tires and can have front shocks to soften the impact when they’re cruising down rough terrain. Plus, fatter tires stabilize the bike, which can help prevent spills. The more gears a bike has, the more choice the rider gets in terms of speed and climbing power going up and down steep hills. Our picks for the best mountain bikes for kids are light but tough. They come with reliable brakes, smooth shifting, and legit suspensions that add up to a positive introduction to an active, nature-based hobby.
