IMPORTANT!
Consult with your health care professional to determine if the DragonflyTM
is appropriate for you.
DO NOT OPERATE THIS EQUIPMENT WITHOUT FIRST
READING AND UNDERSTANDING THIS MANUAL.
IT IS RECOMMENDED THAT INITIAL SETUP OF THIS
HANDCYCLE BE PERFORMED BY A QUALIFIED
TECHNICIAN, SUCH AS A WHEELCHAIR OR BICYCLE
MECHANIC.
AS WITH ANY THREE-WHEELED VEHICLE, SIDE-TO-SIDE
STABILITY IS DECREASED COMPARED TO A WHEELCHAIR
ALONE, SO USE CAUTION WHEN TURNING AT HIGH SPEEDS.
Follow the recommendations in your wheelchair manual.
The Dragonfly
TM
The operation of a handcycle involves a certain level of risk and the potential for serious
bodily injury.
is intended for use for mobility in sporting and/or recreational purposes only and
is not intended as an exclusive means of mobility. Check local vehicle/wheelchair regulations.
1. Wheelchair Requirements
As part of our installation process, you will attach our mounting clamps onto your
wheelchair.
Our wheelchair attachments fit most wheelchairs. However, a few wheelchairs will not fit
our clamps. Use this guide to determine if our devices are right for you.
There are five points that must be considered in order to determine whether your
wheelchair is compatible with our wheelchair attachments:
1) Seat width. Must be between 14 to 22 in -or- 35.5 to 55.8 cm
(measured end-to-end on the width of your seat cushion).
2) Tube diameters. Currently supported tubing diameters are:
(printable tubing ruler on next page).
• 7/8 in -or- 22.2 mm
• 1 in -or- 25.4 mm
• 1.125 in -or- 28.6 mm
• 1.2 in -or- 30.5 mm
• 1.25 in -or- 31.8 mm
If your tubing is a different shape or diameter contact sales@riomobility.com
3) Tube clearance. To attach the clamps, 1.25 in -or- 32 mm clearance is required.
Diagrams with examples of tube clearances are given in the following pages.
4) Tube angle. Ideally the tubes should be vertical or close to vertical. However,
installation is possible with tubes that taper inwards with slight angles, the larger the
taper angle the more challenging it is to use our “Quick Release Coupler” attachment.
See the diagrams on the following pages where illustrations of wheelchair designs with
tapering tube angles are shown.
5) Footrests on folding chairs. Removable footrests can pose challenges for our clamp
installation, so please consult below where examples of wheelchair designs with
removable footrests are given. Never mount our clamps directly onto removable
footrests as they were not designed to take such riding forces.
The DragonflyTM is compatible with almost all wheelchairs without the need for any
special adapters.
Anti-Tips
&
Seatbelts
When seated in the wheelchair, your center of gravity must be
far enough forward as 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
detaching the handcycle. 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.

The installation of the clamp and frame system for the Dragonfly™ is the
same as the Firefly™.
Set handcranks so that your arms are slightly bent, not locked and it clears
your legs on the downstroke.

The optimal installation angle for your handcycle attachment
Good:
1) The chair clamps mounted
high on straight tubing
2) Tire is as close to the foot
rest while still allowing
ample foot clearance from
the tire while steering
3) The handlebar is high
enough to clear the knees
and allow body torso
clearance when steering
Bad:
1) The chair clamps are
mounted too low
2) The tire is too far from the
footrest
3) At this angle the pedals will
be too close to the rider’s
knees.
4) There needs to be adequate
clearance between the
pedals and your knees
5) Lost traction from the
chopper like angle
Good:
1) The chair clamps mounted
high on straight tubing
2) Tire is as close to the foot
rest while still allowing
ample foot clearance from
the tire while steering
3) The angle is more upright
than the Firefly. You need
to add some core weight on
your pedal downstroke
4) The handlebar is high
enough and out of the way
to clear your knees
Pedal forward to move forward, pedal backwards to brake.
Shift the gears to change the speeds.

L-Bracket (brake handle and shifter) placement
Use this guide as a reference to make sure you place the L-bracket mount with the shifter and
brake lever at the best location, while maintaining clearance for the rotating hand cranks. Be
sure to check that the wires coming out of the brake lever and shifter are not in the way of your
rotating hand crank. Also make sure that the right pin quick release button does not run into
the chain guard. If so, you can slightly bend the chain guard away from the right pin.
Angled Poorly
Best Placement
Incorrect Level
Not Recommended
The bracket should be low and near
the fork clamp. This gives 1” / 25mm
clearance between the shifter and
left crank arm. There is clearance to
access the parking brake.
The location is good but the brake
lever is too close to the chain. There
should be at least 1/2” / 12mm
minimum between the brake lever
and the chain.
The shifter should not be level w/ the
pedal QR pin.
The shifter should not touch the
inside of the left crank arm.
