A:Answer The handlebars are not adjustable. I measured mine this morning and the distance from the part where you stand (platform) to the handle bars is 36 inches. I have a 7 and 9 year old grandson and the height is ok for them. If you are worried about your son being too big, you might consider buying the Hover-1 Alpha model. It is 41 inches from the platform to the handlebars, It is faster and more powerful than the Rally. My seven year old grandson loves it even though the handlebars are about as tall as he is. I consider the Rally to be more of a younger kids scooter and the Alpha more of a teenager/adult scooter.
