ProSeries Model AmTryke
The AmTryke ProSeries tricycle was specifically designed in response to therapists' requests for a more traditional style tricycle for children with special needs, up to approximately 15 years old. The ProSeries tricycle is recommended for children with mild to moderate levels of physical disability who have low muscle tone, as well as decreased strength and endurance. Optional accessories can be added to increase support at the head, trunk, pelvis and feet as needed.
Fitting a wide range of children with special needs, the ProSeries tricycle comes standard with three foot crank positions and four seat post positions. This adjustability allows for years of growth for the tricycle for a child OR for use with multiple children of varying sizes. The positive drive action foot crank mechanism maximizes therapeutic benefits for children in therapy clinics, school, or at home.
