I purchased two Ezy Rollers for use at the youthclub. They are simple to put together, able to be built in two different sizes for use with different size children. They are very easy to use with no real skill necessary and so they are always in demand by a wide range of young people. It is one item that can be used successfully by children that find sport too demanding and kids that would not commit time to learning a discipline such as unicycling.
A really simple concept used to give a lot of fun for a very wide age group.
