The Adventurer Series is our line of upright adaptive tricycles designed for teens and adult riders. This Series is available in two sizes, the AS2000 and the AS2600. It can accommodate riders 14 years old all the way through to adulthood. It’s also our largest bike series, supporting riders up to 300 lbs. The Adventurer Series provides older riders with the same adjustability and built-in room for growth as our Discovery Series, which makes it a bike for life so riders can enjoy the therapeutic and recreational benefits of riding for many years.
