Modular mobility systems

A modular mobility system comprising:

• a mobility base comprising a plurality of rear wheel axle positions, wherein the mobility base comprises a first side frame connected to a second side frame such that a first opening is formed between a first front wheel of the first side frame and a second front wheel of the second side frame and a second opening is formed between a first rear wheel of the first side frame and a second rear wheel of the second side frame, the first and second openings separated by a cross bar connecting the first and second side frames of the mobility base, the cross bar separating the first front wheel and second front wheel from the first rear wheel and second rear wheel, and wherein the mobility base comprises a first interface plate located on the first side frame above the cross bar, the first interface plate comprising a guide rail extending inwardly from a first side of the interface plate toward a second interface plate located on the second side frame above the cross bar and extending along a curved edge of the first interface plate from a first straight edge of the first interface plate to a second straight edge of the first interface plate, and wherein an interior surface of the first interface plate is configured to receive and release a pin at any one of a plurality of angles between the first edge of the first interface plate and the second edge of the first interface plate;
• and
• a wheelchair module removably coupled to the mobility base at the first and second interface plate,
• wherein a first rear wheel axle position of the plurality of rear wheel axle positions is configured to receive a first rear axis wheel, and a second rear wheel axle position of the plurality of rear wheel axle positions is configured to receive a second rear axis wheel, wherein the second rear axis wheel has a diameter larger than a diameter of a first rear axis wheel.
