3.2 The user
Power assist devices are designed to support
users in their daily acvies. Instead of making
the user more passive, like a fully electric
wheelchair, the add-on of a power assist device
helps to stay acve. Especially WheelDrive,
with its unique dual rim concept, encourages
the user to keep propelling with the support of
the Assist Rim. But it also supplies connuous
support with the Drive Rim.
The user must be able to esmate and correct
the results of acons taken when operang the
wheelchair. The user of the WheelDrive should
have experience with a manual wheelchair.
Both le and right wheels work independently
from each other. The WheelDrive is not
intended for one hand operaon.
The user must be familiar with the contents of
the user manual before using the WheelDrive.
In addion, the user of the wheelchair must
have been given thorough instrucon in using
the wheelchair by a qualied specialist before
parcipang in trac. The rst sessions in the
wheelchair with the WheelDrive should be held
under the supervision of a trainer/advisor.
Please contact your dealer in case of quesons.
Warning!
The user of the WheelDrive is responsible
for complying with the applicable local
safety regulaons and guidelines. Contact
your dealer for informaon about
regulaons applicable to your usage
condions.
Driving with the WheelDrive under the
inuence of medicines that can aect your
ability to drive is not permied.
Driving with the WheelDrive without
sucient eyesight is not permied.
No more than one person is to be seated in a
wheelchair with the WheelDrive at a me.
Do not allow young children to drive
unsupervised in a wheelchair with the
WheelDrive.
3.3 The wheelchair
The WheelDrive is compable with most
common wheelchair frames in the market. A
complete list of known compabel wheelchairs
is available on www.wheeldrive.eu. The
installaon can be done with a number of
standard parts, supplied with the WheelDrive
wheels. For each wheelchair frame model a
dierent seng is needed. Once a wheel is set
for a certain frame, it cannot be put directly
onto another frame; an adjustment to the
sengs is required. This is not to be done by
the user. Please contact your dealer for support.
3.4 Use environment
This WheelDrive has been designed for
both indoor and outdoor use (and as such is
classied as a class B system according
EN12184:2014). When driving the wheelchair
with WheelDrive outdoors, it is advised to
drive on paved roads, pavements, footpaths
and bicycle paths. Adjust the speed to suit the
environment.
Cauon!
Do not use the WheelDrive when
temperatures are below -10°C or above
+40°C.
Do not use the WheelDrive when humidity
is below 10% or above 80%.
Only drive on rm surfaces. Avoid loose
gravel, sand, mud, snow, ice or deep
puddles. Drive carefully on roads which are
slippery as a result of rain, ice or snow!
Clean the system aer driving in wet
weather by drying the product with a cloth
or towel.
Do not drive through puddles of water – the
WheelDrive is so called splashing water
proof (normal outdoor rain condions).
Never submerge any part containing
electronics in liquids.
Prevent the WheelDrive from coming into
contact with sea water: sea water can cause
corrosion and may damage the system.
Prevent the WheelDrive from coming into
contact with sand: sand can come into
the moving parts of the system, causing
unnecessary fast wear of these parts.

WheelDrive user guide I version 1.00 | 13-4-2021 11
Warning!
It is advised to select a low assistance level
when driving indoors, on pavements and
in pedestrian areas (see paragraph 4.2 for
more informaon).
Take extra care when driving at higher
speeds.
Beware that in dicult situaons you should
be able to switch to the Assist Rims.
Take special care when driving down slopes
of any kind. Adjust your speed to maintain
safe control.
It is advised to use the Assist Rim when
driving up or down a slope. Before you use
the Drive Rim on slopes, make sure you are
familiar with the use of the Drive Rim e.g. by
learning on slight slopes. In case you want to
use the Drive Rim on slopes, make sure that
you select a sucient speed level before
you start to take the slope.
Less charged baeries can supply less
power than fully charged baeries. For
taking slopes at least 2 LEDs of the baery
indicator should be on.
When descending with Assist Rims, the
system will reach and keep a maximum
speed of ~15 km/h . Exceeding this speed
is not possible. This speed is seable by an
authorized person.
Do not drive o obstacles higher than 50
mm.
Overcome obstacles only by driving
backwards, if possible.
Do not aach any heavy objects to the
WheelDrive system or wheelchair frame
without the approval of a qualied
specialist. This may negavely aect the
stability of the product.
Beware that each WheelDrive wheel is a few
cm wider than a standard manual wheel; be
careful taking narrow doors and hallways.
3.5 Soware adjustment opons
The electronics of the WheelDrive are
programmed to an average usage/driving
prole – several parameters are available
that can be adjusted to inuence the driving
behavior. Please contact your dealer about
possible adjustments.
Warning!
Only an authorized person is allowed to
make any adjustments and program the
WheelDrive.
Incorrect programming can lead to
unexpected driving behaviour.

WheelDrive user guide I version 1.00 | 13-4-202112

The baery indicaon on the user interface
shows the remaining baery capacity of the
wheel. For more informaon see paragraph 4.3.

WheelDrive user guide I version 1.00 | 13-4-202114
4.3 Charging the baeries
Each wheel has a separate baery. Both
baery packs need to be charged separately.
Both chargers can be used for both baery
packs. Baeries can be charged when they are
mounted on the WheelDrive. The baeries can
either remain on the wheels or be taken o for
charging.
In case the WheelDrive is switched ON, the
charging level of the main baery is indicated
via the baery indicaon LEDs on the user
interface (gure 5). During charging, the LEDs
that are ON, indicate the charge percentage.
The remaining LEDs light up stepwise, as
shown in gure 6. When the baery is parally
charged, only the last few steps will be shown.
When all LEDs are ON (permanent step 5), the
baery is (almost) fully charged.
Only use the supplied baery chargers to
charge the baery packs (gure 7). The
baery packs include electronics to control
the charging process – it will stop the charging
process when the baeries are fully charged;
overloading is not possible.
Each baery pack has a charge connector with a
black cover. Open the cover and insert the plug
with the at side to the right (gure 8).
During charging the LED on the charger will
turn red.
When the baery is fully charged, the LED
indicator of the charger will turn green. Now
you can disconnect the plug. Please pull at the
plug itself, not the cord. Aer disconnecng the
plug, close the black connector cover to prevent
water and dirt coming in.
Note!
The charger plug is not properly connected
when the red light on the charger ashes.
Remove the plug from the baery and
reinsert it. If the light keeps ashing please
contact your dealer.
To prevent you from geng into a situaon
where no power assist is available, it is
strongly recommended to charge both
baeries every day.
Please note that baeries can discharge
dierently (max 10%).
Before driving, be sure the baeries are
suciently charged.

Cauon!
Only use an original baery charger,
distributed by the manufacturer, to prevent
dangerous situaons.
Never subject the charger to humidity –
only use it indoors.
Never charge the baery packs at
temperatures below 10°C or above 30°C.
Do not store baeries at temperatures
higher than 35°C (this will reduce the
service life signicantly).
Charge the baery pack completely before
long-term storage, and check the charge
level every 3 months. Even not-used
baeries will discharge slowly; prevent
the baeries to become completely empty
(deep discharge of the baeries will damage
the baeries).
Remove the charger when baeries are
completely charged.
Always pull the plug (not the cable) to
remove the baery charger from the mains
or charge connector.
Always aach the black connector cover if
no baery charger is connected, to prevent
water and dirt coming in.
Warning!
In case the baeries are completely
empty the WheelDrive will shut down
automacally to prevent deep-discharge
(and damaging) of the baeries. At this
point the wheelchair can sll be used as a
manual wheelchair, but power assistance is
not available anymore.
The power assist cannot be used during
charging; do not drive if the baeries are
being charged while aached to the wheels.

4.5 Driving - using the rims
Assist Rim (A in gure 11)
The outer ‘Assist’ Rim allows for self-propelling,
just like driving a manual wheelchair but with
electric assistance. The support is dependent
on the selected assistance level and force
applied to the rim.
Assist Rim usage
When applying more force on the Assist Rims,
the system will give more support. When less
force is applied on the Assist Rim, the system
will give less support. In this way the required
speed can be controlled.
Braking with the Assist Rim
Braking with the Assist Rim is comparable
with braking with a manual wheelchair. When
the system is on, the WheelDrive oers
addional motor support when moving the
rim backwards. The user is part of the braking
system.
Warning!
The Assist Rim is connected to a sensor. Do
not use the Assist Rim to lean on, for making
a transfer from or to your wheelchair.
Drive Rim (B in gure 11)
This rim works dierently than the Assist
Rim. The smaller inner ‘Drive’ Rim provides
connuous drive, enabling the user to drive
fully electric with no eort required. If the
system is turned o, the Drive Rims have no
funcon.
Drive Rim usage
As long as the Drive Rim is pushed forward,
the wheelchair will move forward. If the Drive
Rim is pushed backward, the wheelchair will
move backward. The Drive Rim can be pushed
forward and backward unl an end posion; in
this posion the speed is maximum. If the Drive
Rim is pushed the speed increases gradually
unl the maximum speed is reached. When the
Drive Rim is released, the motor support will
stop. The wheelchair will not immediately stop,
but gradually brake on the motor.
Braking with the Drive Rim
By pushing the rim carefully backward, the
speed decreases. This way you can break with
the Drive Rim. By moving the rim even more
backward, the wheelchair comes to a stop and
then moves backward. The acceleraon and
maximum speed diers per driving prole.
The system automacally stops accelerang
when the maximum speed seng is reached,
and tries to keep the maximum speed constant
at this value.
Warning!
While using the Drive Rim, beware not to
put your ngers too far inwards between
the spokes of the wheel. Pay aenon with
clothes that can get caught in the spokes.
If you do not feel secure, it is advised to use
WheelDrive spoke protecon. Only use the
original spoke guard that is developed for
the WheelDrive.
Always use the Drive Rims in a smooth
and uniform way to get the best driving
experience.

4.6 Obstacles and slopes
Take extra care when taking obstacles (such
as thresholds, curbs and narrow doors and
hallways) and when driving on slopes. Only use
the WheelDrive in situaons where you would
feel safe with a normal manual wheelchair
without WheelDrive.
Make sure that you rst exercise with both rims
to get familiar with their funcons before taking
obstacles and slopes.
It is advised to use the Assist Rim for taking
obstacles and slopes. This way you have the
best control for driving and braking.
Taking obstacles
The WheelDrive is cered for taking obstacles
up to 50 mm. Obstacles higher than 25% of the
front wheel diameter might be easier to take by
backward driving. Low obstacles can be taken
by forward driving. The size and construcon of
the front wheels of your wheelchair are of great
inuence on taking obstacles. Drive carefully
towards the obstacle with the front wheels.
Select the appropriate prole and then take a
short run up (15-20 cm) to climb the obstacle.
Warning!
Do not drive o/over high obstacles
(higher than 50 mm).
Note!
Obstacles higher than 25% of the front
wheel diameter should be taken by
backward driving.
Driving up a curb
1. Choose the place where the curb is
at its lowest or slanted/sloped.
2. Drive straight up to the curb at a
right angle to it (15-20 cm in front of
the curb).
3. Propel the Assist Rim forward.
Drive up the curb without changing
direcon.
4. Maintain speed unl all of the wheels
are on the sidewalk.
Driving down a curb
1. Choose the place where the curb is
at its lowest or slanted/sloped.
2. Drive straight down the curb with
your front wheels at a right angle to
it.
3. Propel the Assist Rim slowly forward.
Drive down the curb carefully, as
slowly as possible and without
changing direcon.
Taking obstacles with help of an aendant
An obstacle can be taken by an aendant
pushing the wheelchair.
Note!
Turn the WheelDrive o before pushing.

WheelDrive user guide I version 1.00 | 13-4-2021 19
Driving on slopes
Warning!
When driving up or down a slope always use
an an-p device.
It is advised to use the Assist Rims when
driving up/down a slope, since you have
direct control for driving and braking.
It is advised to use fully charged baeries
when driving up a slope (less charged
baeries can supply less power than fully
charged baeries). For taking slopes at least
2 LEDs of the baery indicator should be on.
When the temperature is below 0° C, the
power of the WheelDrive is reduced to
protect the baery. This might aect the
ability to take slopes.
Only drive on slopes in case you would feel
comfortable doing so (even) with a manual
wheelchair without WheelDrive.
Avoid sudden, jerky movements; always
drive carefully and with the highest
concentraon.
Avoid making emergency stops on a slope.
Avoid changing direcon on
a slope whenever possible.
Do not drive on slopes with loose gravel or a
sandy surface, as one of the driving wheels
could slip/spin.
If you noce a signicant decrease in speed
when driving up a slope, try to take a route
which is less steep.
Take special care when driving down slopes
of any kind. Adjust your speed to maintain
safe control.
The stopping distance driving down slopes
can be signifacantly greater than on level
grounds.
When descending without using the Rims,
the motor can start generang energy and
charging the baery when braking on the
motor is acvated.
Warning!
When descending with a too high speed, the
WheelDrive can shut down automacally
due to over-voltage. The wheels connue
to run, but power assistance is not available
anymore.
Driving up slopes with Assist Rim
1. Propel the Assist Rim slowly forward.
2. When releasing the Assist Rim, the
motor brakes and prevents going
backwards.
3. The Assist Rim can now be propelled
forward again.
4. Repeat steps 1-3 unl the complete
slope is taken.
Warning!
When pushing yourself away, e.g. from a
table, the brake funcon as described above
might get acve: To avoid this always push
back only with a very low speed.
Driving down slopes with Assist Rim
When driving down slopes with the Assist Rims
and you want to slow down, you can push back
the Assist Rims soly. The motor will brake and
keep the speed constant.
Warning!
When the absolute speed limit is
reached, the user ice a small dierence
between both wheels. This may cause the
WheelDrive diverge from its direcon.
When driving down slope use both Assist
Rims to correct the driving direcon.
Using only one of the Assist Rims might
result in braking on one side and cause an
unexpected turn.
Driving down slopes with Drive Rim
Driving down slopes with the Drive Rim oers
a max speed of 6 km/h which can make it more
easy to drive a constant speed.

4.7 Mounng and dismounng a
WheelDrive
WheelDrive is designed to t most common
manual wheelchair frames and can be installed
without making adjustments to the wheelchair
frame itself. In some cases re-adjustment of
front wheels is required aer replacing manual
wheels for the WheelDrive. The WheelDrive
wheels can be taken o for transport or
changing them for manual wheels. A complete
list of known compabel wheelchairs is
available on www.wheeldrive.eu.
The WheelDrive wheels can easily be taken o
for transport or to change them for manual
wheels. The WheelDrive is mounted on a
wheelchair frame by making use of a quick
release axle, as shown in gure 13. The size and
seng of the quick release axle is dependent
on the brand and type of your manual
wheelchair frame and determined by your
dealer.
At the rear side of a WheelDrive wheel there
is an an-p plate in which 2 cone-shaped
supports are screwed (gure 12). The posion
of the supports is dependent on the brand and
type of your manual wheelchair frame and
determined by your dealer.
Dismounng a wheel (gure 13)
By rotang the quick release handle upwards,
the quick release handle will be placed in the
correct posion. Unlock the axle by pushing the
unlock buon just above the handle with your
thumb. Now the wheel can be removed from
the chair. The easiest way to do this is by liing
the chair a lile bit.
1. Pull the quick release handle
vercally up.
2. Push the buon to release the quick
release axle.
3. Pull the quick release handle to
dismount the wheel.
