Evolutionary balance bike with double rear wheel convertible into single wheel thanks to spacers stored in the fork. The Yvelo Junior balance bike is back after getting a makeover! But rest assured, its characteristics are identical: it is always scalable and essential, we have simply reworked its ergonomics for ever smoother learning! From 18 months, your child can use it with the two rear wheels for more stability. By starting gently, he acquires balance and confidence for learning at his own pace. Once comfortable, it is possible to remove one of the two rear wheels to increase the instability of the Yvelo Junior and thus allow the child to continue his motor development. The handlebars and the saddle are easily adjustable in height. They have been redesigned to better accompany the child in his learning period with a smaller than average handlebar diameter and a more comfortable saddle. When he is ready to start learning to ride a bike, the notion of balance will be acquired and the small stabilization wheels will no longer be necessary! Steel frame. Comfortable and adjustable saddle in 3 positions (from 28 cm to 36 cm) for more comfort. Handlebar adjustable in 3 positions (from 44.5 to 47.5 cm), with soft rubber grips. Non-slip rubber wheels for smooth learning. Reduced handlebar diameter for better handling by young children. Rolling wheels for durability and smoothness. Scalable double rear wheel for smooth learning from 18 months. Maximum user weight: 20 kg. Assembly instructions included. Balance bike net weight: 3.6 kg.
