Using the Yvolution 4 - in - 1 Convertible Balance Bike and Trike is super easy. For the push trike mode, just let your child sit on it and guide them with the easy - to - steer design. When your child is ready to practice more skills, they can ride it like a normal trike to build confidence. To turn it into a balance bike with a push handle, fold the back two wheels together and put the parent's handle back on. This way, you can keep your child stable as they learn. Once they're confident enough, take off the handle for independent riding. As for maintenance, keep it clean after use. Wipe it down with a damp cloth. Check the screws and parts regularly to make sure they're tight. Also, don't let it get too wet or leave it in extreme weather conditions. Always ensure your child wears proper safety gear like a helmet when riding, and make sure the rider's weight doesn't exceed 44 lbs and their height is between 14 and 16 inches.
