The Staircycle. Gotta feeling this should have been called the StepCycle, but hey. $795.00 plus $199.00 for the indoor trainer attachment option (which lifts the back wheel off the floor).
Simply, it is the cross between an adult sized scooter and stair climber that moves you. Using a very unique transmission set, it allows for completely independent motion of each pedal. Easy to balance, you can take large or small steps to suit you. No matter what, you are moving forward and exercising indoors or outdoors. The adult version has 8 speeds available and the childrens have 3 speeds.
