My great nephew Ben got to experience his first big boy bike yesterday. It is a Sun Matrix 20” in black and blue. He opted for the training wheels to get started but has plans to ditch them ASAP! The Matrix series (16 or 20”) is ideal for beginning riders because of the “cut down” frame design, allowing young riders to easily straddle the bike. This affords early riders with a sense of control and stability improving their confidence and ensuring success. Happy riding Ben – Uncle Brooks loves you and really likes seeing you on your new bike.
