What is the recommended age for users of Roller?

Children can begin using Roller as soon as they have too much weight to carry to school (more than 10% of their body weight), this usually happens around 7 years of age although it will greatly depend on the school.  The light aluminum telescopic tube has 3 adjustable height positions and it can therefore adapt to the growing child.  Roller XL has 40% more capacity and is therefore usually recommended for children 10 years and older.
