5 Introduction
Before starting your first trip, familiarise your-
self with these usage instructions and the us-
age instructions for the coupled wheelchair,
paying particular attention to all the safety in-
formation and hazard warnings they contain.
Allow your therapists and doctors to advise
you, your carers, and assistants on how to use
the product and what you are safe to do with
the product based on your current ability.
Under no circumstances should you do
anything with or in the product which you have
not learnt to do and have not mastered.
You, your carers, and assistants should also
seek advice from your therapists and doctors
as well as the rehabilitation specialist dealer
about the use and settings of your product as
well as all the safety accessories available
(e.g. chest belt and waist-belt).
It is then vital that the advice from doc-
tors, therapists and the rehabilitation specialist
dealer on the necessary safety accessories
should be followed.
If you are not sure how to handle the
product or if technical faults occur, please con-
tact your rehabilitation specialist dealer or
PRO ACTIV before using it.
When operating the product, the wheel-
chair usage instructions must also be ob-
served. Information on limit values must not be
exceeded. If the values in the two sets of us-
age instructions differ, the lower limit is the one
which applies.
Never leave the product unattended.
Secure the product against unauthorised
use and theft.
When combining your product with
equipment made by other manufacturers,
make sure that the individual components and
the unit made up of them still work appropriate-
ly. You can get information on the suitability of
a combination from the manufacturer of the
third-party components or from your rehabilita-
tion specialist retailer.
The product contains small parts that may
pose a choking hazard for children.
The wheelchair with the adapted product
must be equipped in accordance with road
traffic regulations when operated on public
areas, roads paths and spaces.
The product may be used only in conjunc-
tion with the approved adapter. Weight limita-
tions must be observed while doing so. The
Heavy Duty version of the product may be
used only with the Heavy Duty version of the
adapter.

6 Purpose and indication
This product is a manual adaptive bike that is
coupled to a human-powered wheelchair with
the aim of preserving or increasing the inde-
pendent mobility of an active wheelchair user
to the greatest extent possible. The active
crank movement of the arms extends the us-
er's radius of action.
Indications: Walking impediment or limited
ability to walk due to paralysis, limb loss, limb
defect/deformation, joint contractions/joint
damage, neurological and muscular diseases.
Contraindications: Progressive muscle diseas-
es, the course of which is accelerated due to
fatigue of the arm and core muscles used (e.g.
muscle dystrophies and atrophies) and ac-
companying epilepsy disorders (legal stipula-
tions on freedom from seizures for a permit for
use on public roads apply here).
In addition - for safety reasons - the product
may only be operated by people who
 can move and coordinate their hands,
arms, and head (when using the chin to
operate the gears if manual function is un-
available) so that they can operate all con-
trol elements and conduct full, unrestricted
steering movements during the trip.
 are physically and mentally capable and
have the visual ability to safely operate the
product in all operating situations and can
meet the legal requirements for use on
public roads. For children or people with
mental, significant motor or visual impair-
ments, the attendants can ensure the re-
quired traffic safety as a substitute and as
a companion.
 have been trained in its use by the rehabili-
tation specialist dealer or PRO ACTIV.
7 Proper use
This adaptive bike is designed to be used out-
doors on tarmac and adequately paved roads
that ensure traction and stability of the product
when driving and braking. When used indoors,
there must be enough space for manoeuvring.
Avoid driving in poor weather conditions (e.g.,
storms) since this can lead to incalculable
risks.
The maximum permitted load of the product in
its standard design is 120 kg towed capacity
and 10 kg payload. The heavy-duty version
and individual customisations can be designed
for a higher load; this is then indicated on the
rating plate. Please ensure that the load limit
indicated on the ratings plate is not exceeded
when transporting objects.
Recommended equipment:
The wheelchair should be equipped with a
wheelbase extension; the maximum permissi-
ble load for the wheelbase extension must be
then be observed. Before driving with the trac-
tion system, the wheelchair wheels should then
be positioned in the wheelbase extension. This
allows better distribution of the weight between
the drive wheel of the product and the wheel-
chair wheels to be achieved. This minimises
the risk of the product wheel slipping on
slopes.
Figure 1: Removable wheelbase extension
Recommended equipment:
The wheelchair can be equipped with an anti-
roll back device that can be activated before
driving on slopes. The anti-roll back device can
also be used if the wheelbase extension is
used on the wheelchair.

ment of safe operation. The product may gen-
erally be used only for applications that are
listed and described in these usage instruc-
tions. This includes storage, transport, mainte-
nance/inspection, and repair, as well as the
safety information in each chapter of these
usage instructions.

you later when handling the product.
During the hand-over, the record of training
(chapter 30) and the hand-over certificate in-
cluding the associated check list (chapter 31)
must be filled in. The rehabilitation specialist
dealer should send the completed documents
to PRO ACTIV for filing as a file by e-mail or in
the form of a copy by fax or in the post.
11 Introduction to the product and
the surroundings
During the initial commissioning of the product,
drive at minimum speed and become accus-
tomed to the driving characteristics of the
product. Always adapt the speed and driving
manoeuvres to match your own abilities, the
external circumstances and the legal regula-
tions. You will get a feel for how to use the
product safely after a short time. Before driving
up or down slopes or hills with the product, you
should be proficient in the safe handling of the
product on level ground. Get familiar with the
braking distance at different speeds.
Get to know the environment in which you wish
to use the product. Look out for obstacles and
learn how to overcome or avoid them.
Get familiar with the road traffic regulations,
since these must be observed when driving on
public roads.
12 Safety instructions – prior to
driving/use
If your wheelchair is operated in combina-
tion with the product, any existing anti-tipping
supports must be put into their passive position
or removed (see the wheelchair's usage in-
structions). If the wheelchair is then used with-
out the product, the anti-tipping supports must
be brought back into their operating position
again to ensure tipping stability.

Usage instructions for NJ1 adaptive bike
8
Before every trip, check the condition of
the wheels of the wheelchair-product combina-
tion (e.g. visual inspection of the spokes and
rims, check the tyres for damage, foreign bod-
ies and crack formation). If you have any
doubts, the wheelchair-product combination
must not be operated any further. In this case,
contact your rehabilitation specialist dealer or
PRO ACTIV.
Check the air pressure in the tyres of the
wheelchair-product combination at regular
intervals. Ensure that you comply with the
manufacturer's specifications which can be
found on the tyres. When the tyre pressure is
too low, it has a detrimental effect on the driv-
ing behaviour and the braking reaction of the
product. Moreover, there is an increased risk of
a flat tyre.
Before starting your trip, check the func-
tioning of the product's brake. If all existing
brakes are not fully functional, no trips may be
taken.
Before every trip, check that the product
is firmly attached to the adapter and that the
adapter is firmly attached to the wheelchair.
The product may not be operated on the
wheelchair if any of the connections are not
tight and secure. In this case, contact your
rehabilitation specialist dealer or PRO ACTIV.
Always ensure that your feet cannot slip
off the footplate support of the wheelchair
when using the product.
Depending on the equipment, the product
may have folding/closing mechanisms that
pose a risk of crushing injuries (e.g. pinching
your fingers). For this reason, please allow
your rehabilitation specialist dealer to explain
how to work these mechanisms and then have
a go yourself under instruction.
Check the function of the front and rear
lights as well as the effectiveness of the side
and rear reflectors before every trip. Lights and
reflectors must be clearly visible during the trip
and must not be covered by objects.
To minimise the risk of suffering serious
head injuries in the event of a fall, a helmet
should always be worn when driving with the
product.
When travelling, always carry a repair kit
and tyre pump for repairs in event of punc-
tured/flat tyre. An alternative to this is an
emergency puncture repair spray that fills your
tyre with a foam that hardens in the tyre.
13 Safety instructions – while
driving/using
The usage instructions of the connected
wheelchair must be strictly observed when
using the product.
Please note that some parts of your prod-
uct can become extremely hot in high ambient
temperatures. This means that above 50°C,
the product may be damaged and above 40°C
there is already the risk of burns for the user,
which should not be underestimated, particu-
larly for people with impaired sensitivity. For
this reason, the product should not be exposed
to such extreme temperatures. PRO ACTIV
cannot accept any liability or provide any war-
ranty for personal injury and material damage
caused by such stresses. Similarly, there are
also certain risks at extremely low tempera-
tures.
Always hold onto the crank handles with
both hands while driving, braking, and
manoeuvring. If a driving situation requires you
to take one hand off the crank handle, make
sure the speed has been reduced to the mini-
mum possible beforehand.
When driving in curves, reduce your
speed to a minimum and if possible, lean your
upper body towards the curve.
Do not ride parallel to slopes and inclina-
tions due to the risk of tipping.
You may only drive on slopes where the
wheelchair-product combination can be safely

Usage instructions for NJ1 adaptive bike
9
controlled by steering and braking of the prod-
uct.
Do not stop on a steep slope, otherwise
there is a risk of losing control of the product. If
possible, do not turn on a slope or change your
direction.
Due to the increased turning circle, it can
be difficult to turn in buildings, in front of or in
lifts or other buildings, as the standard in such
buildings assumes a maximum turning circle of
1.5 m.
Do not attach objects (carrier bags, etc.)
to the product. These could prevent safe oper-
ation of the product while driving.
At twilight and in the dark and in bad light-
ing and weather conditions, always switch on
the lights on the product and on the coupled
wheelchair.
When driving in areas that are approved
for pedestrians, keep to the maximum permit-
ted speed (walking speed 6 km/h) and main-
tain sufficient lateral distance (at least the
width of a wheelchair) from obstacles and oth-
er road users.
When driving on public areas, roads,
paths, and spaces, the provisions of the road
traffic regulations must be observed.
Avoid driving on unpaved or loose sur-
faces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
When travelling on poorly maintained
paths (e.g. coarse gravel, potholes), there is an
increased risk of puncturing your tyres as well
as tipping.
You must not make telephone calls while
driving.
The product can affect other devices, for
example theft protection barriers in department
stores.
By performing regular checks, ensure that
the safety bolts of the adapter are always in
the correct position while driving (see usage
instructions "Adapter and adaptation").
When driving, never jerk the handlebar,
as this could possibly cause the wheelchair-
product combination to tip over sideways.
While driving, never grab onto the wheel-
chair wheels, in the area of the product wheel,
in the area of the chain / sprockets / chain
wheels, or into other rotating parts; if you do,
you may cause injuries.
Only brake the product using the service
brakes.
During long trips the brakes of the prod-
uct may heat up. Therefore, do not touch the
brakes immediately after the trip.
If the situation allows it, the speed should
be reduced by carefully applying the service
brake. Abrupt braking can cause the upper
body to fall forwards which can thereby result
in injuries or loss of vehicle control.
If the weight load on the drive wheel de-
creases (e.g. when driving on slopes) or when
driving on loose/slippery surfaces, the braking
action of the wheel may be considerably re-
duced. The driving style and speed should be
adjusted so that the product can be safely
stopped at all times using the brakes.
Towing or using a trailer is not permitted.
Make sure that cables and lines are not
kinked or tangled somewhere. This could
cause them to be damaged which could lead to
the brakes and gear shift not working correctly.
In this case, the product must no longer be
operated.

Usage instructions for NJ1 adaptive bike
10
14 Safety instructions regarding
obstacles
Driving on steps and escalators with the
product is forbidden.
The maximum obstacle height which can
be negotiated is 10 cm. This value can, how-
ever, be reduced due to the specifications of
the type of wheelchair or its settings. There-
fore, you should observe the values given in
the wheelchair's usage instructions or the re-
strictions dependent on the settings.
When driving over or passing obstacles, it
is important that you avoid any product or body
parts catching on the obstacle as this may lead
to falls causing serious injuries to the user and
third parties as well as damage to the product.
Always drive over curbs or other obsta-
cles so that you cross them to the front or at
right angles and at the minimum required
speed. If you approach them at an angle or
pass over an obstacle with just one rear wheel,
there is an increased risk of tipping over to the
side.
15 Safety instructions regarding
dangerous locations and dan-
gerous situations
The operator of the product determines the
route to be driven themselves, taking the us-
age instructions, their driving knowledge, and
physical abilities into consideration.
Personal driving skills are particularly important
in the following dangerous locations that are
provided as examples; the product user must
use their judgement before driving in such
locations:
 quay walls, landing and berthing locations,
paths and locations close to water, unse-
cured bridges and dykes.
 narrow paths, slopes (e.g. ramps and
driveways), narrow paths on a slope,
mountainous routes.
 narrow and/or steeply sloping paths along
main roads or near cliffs.
 routes that are covered in leaves, snow or
ice.
 ramps and lifting equipment on vehicles.
When driving in a curve or turning on hills
or downward slopes, there may be an in-
creased tendency to tip over to the side due to
the changes in the centre of gravity. Avoid
such driving manoeuvres. If these cannot be
avoided, perform these driving manoeuvres
with increased caution and only at a very slow
speed. If necessary, the driving manoeuvre
must not be performed or only with the help of
an assistant.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
When waiting at potential hazard areas
(e.g. while waiting at a pedestrian crossing, on
hills or slopes or at ramps of any type), always
hold down the service brakes.
Extreme caution is needed when crossing
main roads, intersections and level crossings.
Crossing rails in the road or at level crossings
must never be undertaken while driving paral-
lel, otherwise the wheels could become caught
which would result in the wheelchair and the
product being unable to manoeuvre.
Before driving on a ramp and lifting
equipment on vehicles, ensure that they are
wide enough so that you do not risk one of the
product or wheelchair wheels slipping off the
ramp. When lifting or lowering a ramp or lifting
equipment, the service brake of the product
should be applied. Always keep the product in
the middle of the ramp.
The grip of the tyres on the ground is
reduced under wet conditions. There is an
increased risk of slipping. Adjust your driving,
braking and steering behaviour accordingly.

Usage instructions for NJ1 adaptive bike

16 Ending the driving operation
To make getting out of the wheelchair more
simple, the product can be disconnected from
the wheelchair (see usage instructions "Adapt-
er and adaptation").
17 Adapter and adaptation
Where necessary and ordered, a suitable
adapter for your wheelchair is included with the
delivery.
Please read the usage instructions and as-
sembly usage instructions "Adapter and adap-
tation" before using the product.
The product may only be adapted and
detached on dry, stable and flat surfaces.
The adapter must at least have the same
user weight approval as the product.
18 Drive wheel and tyre pressure
Check the tyre inflation pressure at regular
intervals as well as after extreme temperature
effects. The recommended tyre pressure is
printed on the side of the tyre. This should
be observed.
Insufficient tyre pressure has a negative
effect on the handling. Apart from that, there is
an increased risk of a flat tyre.
If the pressure is too high, the tyre may
burst. For this reason, product tyres may not
be exposed to unusually high temperatures
such as under glass in the summer.
When inflating the tyres, make sure that
the prescribed air pressure is not exceeded.
To check or correct the tyre pressure, pro-
ceed as follows:
1. Secure the product to prevent it rolling
away.
2. The drive wheel is normally fitted with a car
tyre valve. Unscrew the valve cap.
Figure 3: Valve with cap
3. Place the valve attachment of the com-
pressed air device or the compressor onto
the valve and, if a clamp lever is available,
secure the connection by applying the
clamp lever.
4. Now check the tyre pressure. If the tyre
pressure does not match the specifica-
tions, correct it.
5. Finally release the clamp lever (if present),
pull the valve attachment off the valve and
replace the valve cap.

19.1 Parking stand
19.1.1 Active and passive positions
By pressing down and turning the operating
lever outwards or inwards, the parking stand
position can be changed from the passive to
the active position or vice versa. The passive
position can also be called the travel position.
The parking stand is then folded in to save
space.

19.1.2 Parking stand height adjustment
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
The height adjustment of the parking stand is
important in order to bring the docking plate of
the product to the correct (height) position
relative to the adapter.
For setting the height of the parking stand, the
following must be observed: the dimension
from the floor to the lower edge of the front of

the insertion maul (on the wheelchair side)
should correspond with the dimension from the
ground to the upper edge of the insertion bolt
(on the product side). As soon as there is a
deviation from these two dimensions due to the
hole pattern, the dimension from the ground to
the upper edge of the insertion bolt may be up
to max. 1 cm larger. In this case, the product
can be inserted into the adapter by tipping
slightly to the rear (via the parking stand).
Figure 9: Measurement from the ground to the lower
edge of the front of the towing attachment
Figure 10: Dimension from the ground to the lower
edge of the insertion bolt
The height of the parking stand is adjusted
by unscrewing the M6 oval head screw (AF
4 mm) with the radius disc and repositioning
the adjustment inlet along the specified row of
holes in the parking stand and inlet. Finally, re-
tighten the M6 oval head screw (AF 4 mm) up
to 11 Nm of torque.
Figure 11: M6 oval head screw with radius disc and
adjustment inlet to adjust the height of the parking
stand or manoeuvring rollers
Information when equipping with manoeu-
vring rollers: After adjusting the height of the
parking stand, the manoeuvring roller must be
positioned in the active position outside on the
parking stand.
19.2 Bottom bracket support and crank
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
19.2.1 Seating position
The seating position and therefore the bottom
bracket position and the crank length depend
on the upper body stability or the core strength.
A suitable adjustment to the arm length will
have been made during the consultation /
measurement procedure.
With weak core strength, the seating position
should normally be chosen so that the upper
body remains still in an upright position when
operating the crank while driving. Rocking
motion of the upper body or the head should
be avoided where possible. The height of the

bottom bracket in this case is selected to be
slightly higher (chest height or higher).
Sporty users with the appropriate trunk
stability relieve their arm muscles by moving
their trunk at the same time. The height of the
bottom bracket in this case can be selected to
be slightly lower (chest height or lower).
The following points must be fulfilled for the
proper seating position:
 The cranks must not touch the knee or
thigh when they are being turned.
 The elbows should not be completely ex-
tended when the crank handles point com-
pletely forward away from the body.
A suitable restraint system must be used
if you have poor seating stability due to a lack
of or weak core strength. The selection of the
suitable system must be made in conjunction
with your doctor or therapist and/or defined
and implemented by your rehabilitation special-
ist dealer. There are various systems available
such as chest straps or four-point safety belts.
Rehabilitation specialist dealers can also often
create a customised system or adapt commer-
cially available systems.
Recommended equipment:
PRO ACTIV also offers restraint systems such
as hip straps with belt and Velcro fastener and
chest straps of various lengths.
19.2.2 Bottom bracket position
In a product equipped with a non-adjustable
bottom bracket support, a subsequent ad-
justment of the bottom bracket position can
only be achieved by exchanging the bottom
bracket support, the angle adjustment possible
on the steering head as well as the length ad-
justment and the spacing of the adapter tube
on the adaptation points on the wheelchair
frame (see usage instructions "Adapter & ad-
aptation").
The bottom bracket support can be exchanged
by loosening the four M6 fixing screws (AF
5 mm) on the tip fork bridge and the four M6
fixing screws (AF 4 mm) on the bottom bracket
housing. Then the new bottom bracket support
with another length can be inserted and the 8
fixing screws tightened up to 7 Nm and se-
cured with thread lock fluid. Finally, check the
chain length and the cable lengths and adjust
them if necessary.
Figure 12: M6 fixing screws on the top fork bridge
Figure 13: M6 fixing screws on the bottom bracket
housing
If your product is fitted with an adjustable
bottom bracket support (optional), the bot-
tom bracket position can be adjusted in angle
and height:
 The angle is adjusted at the top fork
bridge. To do this, loosen the four M6
clamp screws (AF 5 mm), on the clamp
slightly so that the bottom bracket sup-
port's angle can be adjusted using minimal
force. The angle adjustment is continuous
(as a guide, there is a 12° scale fitted).
When you have finished adjusting the an-
gle, tighten up the four M6 clamp screws

(AF 5 mm) to 7 Nm torque and secure
them with thread lock fluid.
Figure 14: M6 clamp screws for angle and height
adjustment of the bottom bracket position
 To adjust the height, two M6 clamp
screws (AF 5 mm) must be loosened on
the bottom bracket housing. Then the bot-
tom bracket housing can be moved along
the bottom bracket support to the desired
position. Then tighten up the four M6
clamp screws (AF 5 mm) to 7 Nm torque
and secure them with thread lock fluid.
For smaller adjustments to the height, infi-
nitely variable adjustments of +/- 25 mm
can be made on the bottom bracket sup-
port. To adjust the height, the two M6
clamp screws (AF 5 mm) must be loos-
ened on the bottom bracket support. Then
the bottom bracket support can be moved
in its mount to the desired position. Then
tighten the four M6 clamp screws (AF
5 mm) to 7 Nm torque and secure them
with thread lock fluid.
Figure 15: M6 clamp screws for adjusting the height
of the bottom bracket position
If you want to make a change to the bottom
bracket position, please contact your rehabilita-
tion specialist dealer or PRO ACTIV.
Please note that, after a large adjustment
to the chain bottom bracket position, the lines
and the cable lengths must be adjusted.
19.2.3 Crank length and grip width
The crank length can be chosen from different
lengths individually to suit the length of the
arms and mobility of the user. Different widths
of bottom bracket shafts and spacers between
the pedal cranks and the rotary axles of the
handles are available to adjust the grip width.
If you want to make a change to the crank
length or grip width, please contact your reha-
bilitation specialist dealer or PRO ACTIV.

19.3 Grips
The grips must be held firmly with both hands
whilst driving and always held so that the ca-
bles and lines are oriented upwards.
Figure 17: Correct grip hold
The cables for the Rohloff hub gear are an
exception for this. If the handles are held cor-
rectly they point forwards into the direction of
travel.
Figure 18: Correct hold of the handle for the Rohloff
hub gear
Always hold onto the crank handles with
both hands while driving, braking, and
manoeuvring. If a driving situation requires you
to take one hand off the crank handle, make
sure the speed has been reduced to the mini-
mum possible beforehand.
19.4 Gear shift
19.4.1 Derailleur
With the derailleur, the gears can only be
changed while the crank is moving. Changing
the gear with the cranks stationary is not pos-
sible. In general, the torque applied to the
cranks should be reduced briefly while chang-
ing the gear so that the gear change can hap-
pen more quickly.
The gearshift control elements are normally
designed so that they can be operated using
thumb / index finger shift control (for mechani-
cal gear systems) or buttons (for electronic Di2
gear systems). With the cassette at the bottom,
switching to the next largest sprocket means a
lower or easier gear and to the next smallest
sprocket a larger or more difficult gear.
Figure 19: Cassette
With the thumb / index finger shift control,
gear changes are achieved by:
 "Thumb shifter" – operation by pressing in
the direction of travel with the thumb
 “Index finger shifter” – operation by pulling
in the opposite direction of travel with the
index finger or using the thumb to press
against the direction of travel.
The mechanical gearshifts do not provide a
display for the gear selected. There is only an
orientation as to which sprocket is currently
being used via a display above the handle.

For more information on derailleur gear sys-
tems, please see the instructions provided by
the gear manufacturer.
19.4.2 Hub gear
The hub drive can be changed while driving
and also when stationary. No crank movement
is needed to change or only a small reduction
in torque is needed while driving.
The Rohloff hub gear and Shimano Nexus
hub gears are operated by turning the grip
shift. The gear selected is shown in the dis-
play on the control element.
Figure 23: Shifting using the grip shift for the Rohloff
hub gear

The rechargeable battery charge level of the
electronic gearshift is also visible on the dis-
play. When the charge state is low (thus when
only one rechargeable battery bar is shown),
the rechargeable battery must be recharged.
Figure 27: Alfine Di2 electronic gearshift battery
For this purpose, the rechargeable battery is
removed as follows: the flap on the side is
opened and the push button is pressed-in (fig-
ure 28). Now the rechargeable battery can be
