IMPORTANT!
Consult with your health care professional to determine if the Dragonfly™is appropriate for you.
DO NOT OPERATE THIS EQUIPMENT WITHOUT FIRST READING AND UNDERSTANDING THIS
MANUAL.
IT IS RECOMMENDED THAT THE 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™ 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. The operation of a handcycle involves a certain level of risk and the potential for serious bodily injury.
Wheelchair Requirements
As part of our installation process, you will attach our mounting clamps to
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:
- 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).
- 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
-
Tube clearance. To attach the clamps, 1.25 in -or- 32 mm clearance is required. Diagrams with examples of tube clearances are given on the following pages.
-
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.
-
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 Dragonfly™ 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 backward
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.
Compatibility Guide for Rigid Wheelchairs
All of our devices require about 1.25 in -or- 32 mm of clearance on the upper
frame tubing.
Compatibility Guide for Folding Wheelchairs
All of our devices require about 1.25 in -or- 32 mm of clearance on the upper
frame tubing. Ideally, this clearance should be above the area where the
removable footrests attach to. 
Installing The Dragonfly™
Visitwww.riomobility.com for the Dragonfly™
installation video:
The installation of the clamp and frame system for the Dragonfly™ is the same
as the Firefly™. Set and cranks 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:
- The chair clamps mounted high on straight tubing
- Tire is as close to the footrest while still allowing ample foot clearance from the tire while steering
- The handlebar is high enough to clear the knees and allow body torso clearance when steering
Good:
- The chair clamps mounted high on straight tubing
- Tire is as close to the footrest while still allowing ample foot clearance from the tire while steering
- The angle is more upright than the Firefly. You need to add some core weight to your pedal downstroke
- The handlebar is high enough and out of the way to clear your knees
Bad:
- The chair clamps are mounted too low
- The tire is too far from the footrest
- At this angle, the pedals will be too close to the rider’s knees.
- There needs to be adequate clearance between the pedals and your knees
- Lost traction from the chopper like an angle
Control
Pedal forward to move forward, pedal backward 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.
Best Placement
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.
|
Angled Poorly
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.
---|---
Incorrect Level
The shifter should not be level w/ the pedal QR pin.
| Not Recommended
The shifter should not touch the inside of the left crank arm.

Maintenance
| Inspection/ Maintenance Item | Initially | Weekly | 6 Months |

All screws must be tightened using a torque limiter wrench (included in packaging). Clean the handcycle with a damp cloth. Do not soak or spray with water or use detergent. Lubricate as necessary after cleaning. Immediately replace any damaged, missing, or badly worn parts with the manufacturer or approved parts. Please contact your dealer or sales@riomobility.com for information on replacement parts. We recommend keeping the box your Dragonfly™ was shipped in; it makes a handy container for storage of your handcycle, your handcycle accessories, the included tools, and the manual for storage and travel. It can also be used to ship the unit to the factory in case of maintenance or warranty repairs.
Troubleshooting
When climbing a hill, the front wheel slips. The front wheel is too far
forward from your center of gravity. Please adjust the handcycle so that the
front wheel is as close as possible to the footrest without interfering while
driving straight or turning. If possible, you may also want to move the rear
axles further back. When climbing hills, leaning forward in your chair may be
necessary.
Check that the front caster wheels are at least 5 cm/ 2 inches off the
ground when the handcycle is installed.
The chain keeps derailing or popping off the cog or chainring.
Check the chain is tight without any slack or play. Make sure the chain is
aligned straight and is not twisted or offset. If the chain needs adjustment,
have one person hold the front wheel, loosen the 2 screws on the fork clamp.
Have a friend pull the cranks up with strong force, make sure the chain is
straight and there is no slack in the chain, then tighten the 2 clamp screws.
The Shimano™ Nexus 8 hub is slipping or falling out of gear.
-
Rotate the shifter into gear #4.
-
Look at the cassette joint bracket on the Nexus Hub system to find the “two yellow lines.” Check that the yellow setting lines on the cassette joint bracket and pulley are aligned with each other. The yellow setting lines are located in two places. Use the one that is easiest to see.
NOTE
If the overlapping area falls short of two-thirds of each setting line, the gears may not be properly engaged during pedaling, resulting in abnormal noise or free spinning of the hand pedals.
-
Adjust the shifter barrel adjuster if necessary to realign the 2 yellow lines.
Turn the
cable adjustment barrel of the REVOSHIFT lever to align the setting lines.
Again, move the REVOSHIFT lever from X to Y, then back to X, and confirm that
the yellow setting lines are aligned.|

Safety
Safety Checklist
- A helmet and safety belt are recommended.
- ALWAYS engage the wheel locks on your wheelchair before attaching or detaching the handcycle.
- ALWAYS check to make sure that your latches are fully engaged before operating your hand cycle.
- Check to make sure all nuts and bolts are tight and all latches are secured.
- Make sure the hand brakes work properly before riding your hand cycle.
- Do not add any parts or accessories not authorized by Rio Mobility to your handcycle. Any addition could be unsafe and will void your warranty.
Before You Ride
Make sure that your Dragonfly™ is installed, adjusted, and maintained
properly. Do not use the Dragonfly™ until you and your health care
professional determine that you have the ability to use it safely in an
uncontrolled environment. Use your wheelchair as described in your wheelchair
manual and use the Dragonfly™ in the same safe manner that you would a
wheelchair with push rims. Follow all additional warnings and instructions for
the Dragonfly™ in this manual.
Outdoor Use
Always watch out for traffic and pedestrians when riding on the road and
sidewalk and follow all traffic regulations. Follow any and all local
regulations that apply to this device.
Turning Stability
Always mind your speed, especially when turning. You should have full control
of your wheelchair at all times. Do not exceed the maximum allowable speed
recommended by your wheelchair manufacturer.
Three-wheeled vehicles are less stable in turns compared to wheelchairs alone,
so be careful to keep all three wheels on the ground and moderate your speed
when approaching curves.
Be careful when reaching and leaning left or right from your wheelchair with
your handcycle attached – the longer wheelbase makes it less stable in
sideways leans than your regular wheelchair. Narrow wheelchairs are less
stable in general, so be extra careful if your wheelchair is particularly
narrow.
Auxiliary handbrake for emergency stopping and parking
Your handcycle is equipped with 2 brakes:
- the main coaster brake works by pedaling backward
- the V brake handle w/ locking parking brake button
Note: should your chain pop or derail “don’t panic” keep your dominant hand on the handle to steer and use your other hand to apply the hand brake to stop.
Obstacles
Be careful going over bumps and curbs over 2 inches (5cm) high. Your front
casters may contact these surfaces, causing a loss of control. Use your
pushrims to get over bumps, NOT the handcycle. You should approach bumps and
curbs straight on and at low speed to avoid injury or damage to your
wheelchair.
Note: Be aware of road surfaces, especially on inclines and declines. Watch
out for water, ice, and oil film.
Transferring
DO NOT attempt to transfer into or out of your chair with the Dragonfly™
attached. You MUST detach the handcycle before transferring.
General Notes & Precautions
Mind your fingers and hands when using your hand cycle. Keep children away
from your handcycle to avoid possible injury to both you and the child. Do not
carry anything that obstructs your view or interferes with the handlebar
operation. Do not put weight on the wings (objects or people). This handcycle
is meant for everyday recreational or general sporting use and is not intended
for use in competition. Rio Mobility is not responsible for any damage or
injury due to misuse of your handcycle.
