Rio Mobility Firefly 2.5 - 1. Wheelchair Requirements; Seat Width; Tube Diameter; Tube Clearance

1. Wheelchair Requirements
The Firefly
TM
2.5 fits most wheelchairs, but our mounting clamps will not fit onto some wheelchairs.
Consider these five items to determine whether your wheelchair is compatible with the Firefly
TM
2.5:
1) Seat width: Must be between 9 and 23 inches (23 to 58 cm).
(measured center-to-center between the vertical tubes where the mounting clamps are installed)
2) Tube diameter: Currently supported wheelchair tube diameters are:
(measured where the mounting clamps are installed)
• 7/8 inch (22.2 mm)
• 1 inch (25.4 mm)
• 1.125 inches (28.6 mm)
• 1.2 inches (30.5 mm)
• 1.25 inches (31.8 mm)
3) Tube clearance: To attach the mounting clamps, 1.25 inches (32 mm) of vertical clearance along the
wheelchair tube is needed. Two inches of clearance extending horizontally both outward to the sides
and towards the rear of the wheelchair is also needed, from the point on the wheelchair tube where the
mounting clamps are installed. Diagrams of tube clearances are shown on the next page.
4) Tube angle: Ideally the wheelchair tubes should be vertical or close to vertical. Installation can be
done on tubes that taper as well, however, the larger the taper angle the more challenging it is to attach
and remove the Firefly
TM
2.5 from the wheelchair. Diagrams on the next page show where the mounting
clamps on wheelchairs with tapering tube angles should be installed.
5) Footrests on folding chairs: Folding or removable footrests can interfere with our mounting clamps.
Diagrams on the next page show examples of wheelchairs with non-rigid footrests. Never mount our
clamps directly onto removable footrests as they were not designed to withstand such riding forces.
Anti-Tips
&
Seatbelts
When seated in the wheelchair, your center of gravity must be far enough
forward to make “wheelies” or tipping backwards difficult. IMPORTANT: If
the chair is set up such that “wheelies” are easy, it may be unstable while
attaching or removing the Firefly
TM
2.5. Anti-tips MUST be installed on
your wheelchair. A seat belt is also strongly recommended.
Wheel Locks
Wheelchairs must have wheel locks installed.
Weight
Combined wheelchair and user weight must be less than 130kg/280lb.
