Using the Globber Go Bike Air is easy. First, adjust the handlebars and seat to a comfortable height for your child. The handlebars can be set at 47cm or 50.2cm from the ground, and the seat has 6 adjustable heights. Start with the low frame position to help your child learn balance easily. As your child gets better at balancing, switch the frame to the high position. When riding, make sure your child is wearing proper safety gear like a helmet. Only allow kids aged 3 or above to use the bike as the frame is designed to support up to 25kg. To maintain the bike, keep the tyres properly inflated. Check the air pressure regularly, as the 10 - inch rubber air tyres are important for a smooth ride. Also, clean the bike occasionally to keep it in good condition and check the frame and parts for any signs of damage.
