Chillafish Bunzi 2-in-1 gradual balance bike and tricycle is uniquely designed to help teach your child balance at his own pace in a fun way. Your child learns to balance step by step on 3 wheels and when it’s ready . on 2 wheels. Made of high-quality ABS material . the frame can switch between a 3-wheel mode to a 2-wheel mode in just a few seconds; no tools required. The back wheels in 3-wheel mode still offer more stability . but are purposely close to each other . hence less stable than a traditional tricycle or 4-wheel ride-on . so your child feels in control of his own balance. The seat grows with your child (8.7 inch / 22 cm in 3-wheel mode to 9.8 inch / 25 cm in 2-wheel mode). Only in this way the new skills of your son or daughter can be better supported . just until he or she has mastered balance and is ready for a bigger balance bike like BMXie2 or Charlie. The silent anti-skid synthetic rubber tires are non-marking; so no worries when your toddler wants to ride inside the house. But the material of the tires is also strong enough to be used outside and to survive the wildest outdoor treks.Bunzi is made of a very lightweight high-quality ABS material (4 .16 pound / 1 .8 kg) . which makes it easy to carry around thanks to the handgrip built into the back of the seat. You can easily bring the Bunzi on all your child’s trips and adventures. Your child can bring along a toy or snack for the ride in the hidden storage box. Your son or daughter will love it and it’s at the same time also very useful to train the fine motor skills of your lovely toddler.With cute bunny-style handlebars . an intuitive form that grows with your child and vibrant colors to display the personality of your child .
