The Weplay Pedal Walker works like a quadricycle. It has two balancing pedals and one pair of detachable handrails. It allows a child to move forward by exerting their own body weight and distributing it across the pedals of the walker. For the more experienced user, the handrails can be removed to encourage higher levels of balance and coordination exercise. Dimensions: 15" x 20" x 22",  Pedal - 11" x 4". Weight  Limit: 110 lbs. Launch date: January 2010.
