• a seat module carried by said frame;
• a vertically extending socket connected to a front end of each of said first and second longitudinal side members of said frame, said socket accommodating a stem of a front caster;
• a first power drive assembly disposed on said frame first longitudinal side member, said first power drive assembly comprising:
• a first swing arm pivotally secured to said frame,
• a first motor mounted to said first swing arm, and
• a first wheel operably connected to said first motor;
• and,
• a second power drive assembly disposed on said frame second longitudinal side member, said second power drive assembly comprising:
• a second swing arm pivotally secured to said frame,
• a second motor mounted to said second swing arm, and
• a second wheel operably connected to said second motor.

A powered wheelchair comprising:

• a tubular frame having first and second longitudinal sides connected by a bridge;
• a battery support subframe secured to said frame, said battery support subframe comprising a pair of side rails, one side rail being secured to each of said first and second longitudinal sides of said tubular frame;
• a seat module carried by said frame;
• a first power drive assembly disposed on said frame first longitudinal side, said first power drive assembly comprising a first motor;
• a second power drive assembly disposed on said frame second longitudinal side, said second power drive assembly comprising a second motor;
• a battery mounted on said battery support subframe for powering said first and second motors;
• a first swing arm pivotally secured to a support extending rearwardly from said frame, said first motor being mounted to said first swing arm;
• and,
• a second swing arm pivotally secured to a support extending rearwardly from said frame, said second motor being mounted to said second swing arm.

A powered wheelchair comprising:

• a tubular frame having first and second longitudinal sides connected by a bridge;
• a first support located on said bridge;
• a second support located on said bridge in a manner spaced from said first support, said first and second supports being bounded by said two longitudinal sides;
• a first power drive assembly disposed on said frame first longitudinal side, said first power drive assembly comprising:
• a first swing arm secured to said first support,
• a first motor mounted to said first arm and,
• a first wheel operably connected to said first motor;
• and,
• a second power drive assembly disposed on said frame second longitudinal side, said second power drive assembly comprising:
• a second swing arm secured to said second support,
