The Jazzy 600 from Pride Mobility is a center wheel drive power wheelchair with 14" drive wheels. Its main feature is known as "Mid-Wheel 6". Mid-Wheel 6 is the combination of a center wheel drive platform with OMNI casters and an independently active front suspension. OMNI casters are round, unlike traditional wheel casters, allowing you to go from surface to surface without any hang-ups. With Mid-Wheel 6 your Jazzy 600 is always on stable ground.
