MID-WHEEL DRIVE POWER WHEELCHAIRS
Heavy-Duty Power. Everyday Freedom.
Don’t be fooled by its name! This Heavy-Duty Alltrack M3 model still features a compact turning radius along with all the power options offered on a Standard M3. The difference is that some components are the heavy-duty version and will resist to heavier users. The Patented Dual-Action Suspension is tuned accordingly and provides exceptional traction and forward stability.Engineered to support users up to 450 lb (205 kg), the Alltrack M3-HD delivers heavy-duty performance without sacrificing maneuverability, comfort or function. With the same compact footprint and turning radius as the standard M3, it easily navigates indoor spaces while providing the rugged durability needed for outdoor exploration. Reinforced components and an optimized Dual-Action Suspension system ensure a smooth, stable ride—no matter the terrain. For users who need more, the M3-HD offers strength, confidence, and complete independence in motion.
