BT-Mg-AS Wheelchair

The BT-Mg-AS is the result of eager customer requests for a lightweight front and rear suspension chair with center of gravity adjustability. The magnesium (*) frame supports custom rear wheel center of gravity adjustment from 1.5" to 4.5" in half inch increments. It is easy to modify and can be adjusted in less than five minutes with a single wrench.

The BT-Mg-AS conveniently reduces weight by utilizing magnesium frame construction, laminated carbon upholstery, Sun Zero G rear wheels and front and rear Frog Legs Ultra-Sport elastic-polymer suspension for increased shock absorption. Add it all up, and you have an Impossibly Light™ four wheel suspension chair! Transport weight is just 12.6 pounds for a 16" x 16" frame and 19.7 pounds for the entire chair (excluding removable seat cushions).

* Magnesium is the lightest structural metal on the planet! It is roughly 35% lighter than aluminum and 62% lighter than titanium by volume, yet has tensile strength comparable to 6061-T6 aluminum. Magnesium alloys are exceptionally resistant to corrosion and boast ten times the vibration dampening capacity of other metals like aluminum, steel or titanium. This makes magnesium the ideal construction material for lightweight shock absorption and smooth riding.
