The MX16 could be your 4 to 6 year old’s first proper pedal bike, with proper brakes front and rear and reach-adjustable brake levers. The fully enclosed chaincase will keep their clothes clean. More upright and slightly heavier than its cousin the Dimension 16, but more economical as a result. This one comes equipped with stabilisers , but these can be removed if your child has already been trained on a balance bike.
