Kids’ bikes with gears and 16” wheels are a rare find, and that’s exactly where the KUbikes 16L MTB steps in. Its automatic 2-speed hub shifts without the need for a trigger or twist grip, allowing young riders to focus entirely on pedaling and steering. It shifts gears at around 8 km/h and is barely noticeable, though undeniably helpful, not just in hilly terrain. The second gear makes longer stretches on flat significantly easier, too, like riding to preschool or on family outings.

Beyond the gearing, the build is of high-quality and thoughtfully tailored to kids: the brakes are reliable, the tires are trail-ready without going overboard, and the frame is sturdy without adding unnecessary weight. At 6.5 kg, the bike isn’t ultralight, but very respectable for a geared model. One weak spot is the rear axle which sticks out a bit too far and can lead to bruised ankles and shins.

On the plus side, the 16L can be customized in the configurator like all KUbikes – both technically and visually. You can add mudguards, a bell, kickstand, and lights at an added charge. And just like with Early Rider or Woom, the higher price tag can be justified by the bike’s high resale value.
