6 Product description / purpose
The product is attached to a manual wheelchair as a mechanically propelled drive unit
which supports the wheelchair user in being
mobile. It is easier to cover longer distances
with ergonomic movement processes using
one's own wheelchair. This expands the activity radius. Through the product's larger drive
wheel and the wheelchair's steering wheels
which are raised from the ground uneven
routes and barriers can overcome more easily
and without danger. The downhill speed can
be regulated via the product's braking systems,
so that downhill slopes can be travelled on
safely.
For safety reasons, the product may only be
operated by persons who
have been trained in its use by the dealer
or PRO ACTIV.
can move and control their hands and
arms so that they are able to operate the

as written evidence and in addition the operating instructions and any other accessories for
your own use. The form for the record of training and the hand-over certificate can be found
in chapters 28 and 29.
It is recommended that you take along an assistant to the training so that, if required, they
can assist you later when handling the product.
During the initial commissioning of the product,
drive at minimum speed and become accustomed 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 regulations. You will get a feel for how to use the
product safely after a short time.
10 Hand-over
The hand-over must be done by your dealer or
a field representative from PRO ACTIV. During
the hand-over, the record of training (chapter
28) and the hand-over certificate including the
associated check list (chapter 29) must be
filled in. The dealer should send a copy of the
completed documents to PRO ACTIV for filing

11 Safety instructions -
prior to driving / use
The operating instructions of the connected wheelchair must be strictly observed
when using the product.
If your wheelchair is operated in combination with the product, any existing anti-tipping
supports must be put into their passive position
or removed (see the wheelchair's operating
instructions). If the wheelchair is then used
without the product, the anti-tipping supports
must be brought back into their operating position again to ensure tipping stability.
Before every trip, check the condition of
the wheels (e.g. visual inspection of the spokes
and rims, check the tyres for damage, foreign
bodies and crack formation). If you have any
doubts, the wheelchair-product combination
must not be operated any further. In this case,
contact your dealer or PRO ACTIV.
Before starting your trip check that the
product's brake functions. 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
dealer or PRO ACTIV.
Always ensure that your feet cannot slip
off the feet plate of the wheelchair when using
the product, if necessary by using a special
fixation device.
If present, 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 journey and must not be covered by
other objects.
Check tyre pressures at regular intervals.
Ensure that you comply with the manufacturer's specifications which are fitted to the
tyres. Tyre pressure which is too low has a
detrimental effect on the driving behaviour and
the braking action.
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.
12 Safety instructions -
while driving / using
Always hold onto the crank handles with
both hands while driving. If the driving situation
requires you to take one hand off the crank
handles, this is only permitted when the speed
has been reduced to the minimum possible
beforehand.
Before driving up or down slopes or hills
with the product, you should be proficient in the
safe handling of the product on the flat.
Increase the speed slowly up to the desired speed.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
When driving round a bend, reduce your
speed to a minimum.
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.
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.
During long trips the brakes of the product
may heat up. Therefore, do not touch the
brakes during or immediately after the trip (e.g.
when detaching or loading the product).
Operating instructions NJ1 Adaptive bike
7
Do not attach objects (carrier bags, etc.)
to the product. These could prevent safe operation of the product while driving.
When driving on areas which are used for
pedestrians, observe the maximum permitted
speed (walking speed 6 km/h) and keep a
sufficient distance (at least the width of a
wheelchair) from the kerbs or other obstacles
and other road users.
When driving on public roads and footpaths, the provisions of the road traffic regulations must be observed.
Avoid driving on unpaved or loose surfaces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
If you encounter new driving situations
which are unknown to you, approach them with
great care. If you consider that the risk is too
high, you must immediately abort the driving
manoeuvre and, if required, call for help to
assist you in extracting yourself from this situation.
You must not make telephone calls while
driving.
Operating 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 operating
instructions "Adapter & Adaptation").
During a trip never jerk the handlebars to
the left or the right, as this may cause the
wheelchair-product combination to tip over
sideways in certain circumstances.
Never drive parallel to slopes.
While driving, never grab onto the wheelchair wheels, in the area of the product wheel
or into other rotating parts; if you do you may
cause injuries.
Only brake the product using the service
brakes.
The product is only designed to be used
to transport persons with limited mobility and
must not be used for any other purpose, e.g.
by playing children or to transport goods.
You may only drive on slopes where the
wheelchair-product combination can be safely
controlled by steering and braking of the product.
If the weight load on the drive wheel falls
(e.g. when driving on slopes) or when driving
on loose / slippery surfaces, the braking action
of the wheel may be considerably reduced.
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.
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.
13 Safety instructions regarding
obstacles
It is not permitted to go down steps using
the product.
Obstacles like curbs, for example, should
always be negotiated driving forwards and
always using the minimum speed required.
The maximum obstacle height which can
be negotiated is 10 cm. This value can, however, be reduced due to the specifications of
the type of wheelchair or its settings. Therefore, you should observe the values given in
the wheelchair's operating instructions or the
restrictions dependent on the settings.
When driving over or passing obstacles,
you must absolutely avoid any wheelchair or
body parts becoming trapped on the obstacle.
This could result in falls, serious injuries to the
user or third-parties as well as damage to the
product and the wheelchair.
Operating instructions NJ1 Adaptive bike
8
Always drive over curbs or other obstacles
so that you cross them to the front or at right
angles. If you drive at them on an angle, or
only have one rear wheel on the obstacle,
there is an increased risk of tipping over to the
side which can result in serious injuries to the
user and third-parties as well as damage to the
product and the wheelchair.
14 Safety instructions regarding
dangerous locations and dangerous situations
The operator of the product determines the
route to be driven taking the operating instructions, their driving knowledge and physical
abilities into consideration.
The personal driving skills are particularly important in the following dangerous locations
which are provided as examples; the product's
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 which are covered in leaves, snow
or ice.
ramps and lifting equipment on vehicles.
When driving in a circle or turning on hills
or downward slopes, there may be an increased tendency to tip over to the side due to
the changes in the centre of gravity. Always
perform these driving manoeuvres with increased caution and only at slow speed. If
required, the driving manoeuvre must not be
performed or only with the help of an assistant.
When crossing main roads, intersections
and level crossings, extreme caution is
needed. Crossing rails in the road or at level
crossings must never be undertaken while
driving parallel, otherwise the wheels could
become caught which would result in the
wheelchair and the product being unable to
manoeuvre.
When driving on ramps and lifting equipment on vehicles, extreme caution is needed.
During the lifting or lowering operation of the
ramp or the lifting equipment, the service brake
should be operated. This prevents rolling
away.
The grip of the tyres on the ground is reduced in the wet. There is an increased risk of
slipping. Adjust your driving, braking and steering behaviour accordingly.
15 Adapter & Adaptation
Where necessary and ordered, a suitable
adapter for your wheelchair is included with the
delivery.
Please read the operating instructions and
assembly instructions for the "Adapter & Adaptation" before using the product.
The product may only be adapted and
detached on dry, stable and flat surfaces.
16 Functional elements
16.1 Parking stand
16.1.1 Active and passive positions
By pressing down and turning the operating
lever, the parking stand positions can be
changed from the active to the passive position, or vice versa.
Operating instructions NJ1 Adaptive bike

Figure 3: Parking stand in the active position
Figure 4: Parking stand in the passive position
16.1.2 Parking stand height adjustment
It is important to adjust the height of the parking stand to bring the adapter into the right
position in relation to the product's docking
plate. Height adjustment is made by loosening
the M6 oval head screw (AF 4 mm) and adjusting the position of the adjustment inlet. Finally,
tighten the oval head screw up to 7 Nm of
torque.
Figure 5: M6 oval head screw and adjustment inlet
to adjust the height of the parking stand
16.2 Pedal bearing support & crank
16.2.1 Seating position
The seating position and therefore the pedal
position and the pedal crank length depend on
the upper-body stability or the core musculature. A suitable adjustment to the arm length
will have been made during the consultation /
measurement procedure.
With weak core musculature, the seating
position should normally be chosen so that the
upper body remains still in an upright position
when operating the crank while driving. This is
particularly important if you have low seating
stability due to missing or weak core musculature. A rocking motion (forwards and backwards) of the upper body or the head should
be avoided where possible. The height of the
pedal bearing in this case is selected to be
slightly higher (chest height or higher).

Sporty drivers with the appropriate trunk
stability relieve their arm musculature by mov-
ing their trunk at the same time. The height of
the pedal bearing in this case can be selected
to be slightly lower (chest height or lower).
Figure 6: Elbows are not completely straight, upper
body is in an upright position
Figure 7: Distance between the crank and the thigh /
knee
The cranks must not touch the knee or
thigh when they are being turned.
The elbows must not be completely extended when the crank handles point completely 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 musculature. The selection of the
suitable system must be made in conjunction
with your doctor or therapist and / or defined
and implemented by your dealer. There are
various systems available such as chest straps
or four-point safety belts. Also, the dealer can
frequently individually make a system or adapt
one that has been purchased.
16.2.2 Pedal bearing position
In a product equipped with a non-adjustable
pedal bearing support, a subsequent adjust-
ment of the pedal bearing position can only be
achieved by exchanging the pedal bearing
support, the angle adjustment possible on the
steering head as well as the length adjustment
and the spacing of the adapter tube on the
adaptation points on the wheelchair frame (see
operating instructions "Adapter & Adaptation").
The pedal bearing support can be exchanged
by loosening the four M6 fastening screws (AF
5 mm) on the tip fork bridge and the four M6
fastening screws (AF 4 mm) on the pedal bearing housing. Then the new pedal bearing support with another length can be inserted and
the 8 fastening screws tightened up to 7 Nm
and secured with thread lock fluid. Finally,
check the chain length and the cable lengths
and adjust them if necessary.

Figure 9: Fastening screws on the pedal bearing
housing
If your product is fitted with an adjustable
pedal bearing support (optional), the pedal
bearing position can be adjusted in angle and
height:
The angle adjustment is done at the top
fork bridge. To do this, loosen the four M6
fastening screws (AF 5 mm), on the clamp
slightly so that the pedal bearing support'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 angle,
tighten up the four fastening screws to 7
Nm torque and secure them with thread
lock fluid.
To adjust the height, two M6 clamp screws
(AF 5 mm) must be loosened on the pedal
bearing housing. Then the pedal bearing
housing can be moved along the pedal
bearing support to the correct position. After this, tighten up the clamp screws to 7
Nm torque and secure them with thread
lock fluid.
Finally, check the chain length and the cable
lengths and adjust them if necessary.
Figure 10: Fastening screws for angle and height
adjustment of the pedal bearing position
If you want to make a change to the pedal
bearing position, please contact your dealer or
PRO ACTIV.
Please note that, after a large adjustment
to the pedal bearing position, the chain length
and the cable lengths must be adjusted.
16.2.3 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 pedal bearing shafts and spacers between
the crank handles and the rotary axles of the
hand grips are available to adjust the grip
width.
If you want to make a change to the crank
length or grip width, please contact your dealer
or PRO ACTIV.

16.3 Grips
The grips must be held firmly with both hands
whilst driving and always held so that the cables and brake lines are oriented upwards.
Figure 12: Correct grip hold
The cables for the Rohloff hub drive are an
exception for this. If the handles are held correctly they point forwards into the direction of
travel (refer to figure 13).
Figure 13: Correct hold of the handle for the Rohloff
hub drive
Make sure that cables and brake lines are
not kinked or caught up somewhere. This
could cause them to be damaged which could
lead to the brakes and gear shift not working
correctly.
16.4 Gear shift
16.4.1 Chain shift
For the chain shift, shifting procedures can
only occur while the crank is moving. Changing
the gear with the cranks stationary is not possible. In general, the torque applied to the
cranks should be reduced briefly while changing the gear so that the gear change can happen more quickly.
The controls for the gear change are normally
designed so that they can be operated using
thumb / index finger switching fittings or
with a chin control (based on the thumb / index
finger switching fittings). With the 9-speed
cassette at the bottom, switching to the next
largest sprocket means a lower or easier gear,
and to the next smallest sprocket to a larger or
more difficult gear. For the 3-speed chain
wheels at the top, the behaviour is exactly the
opposite.

With the thumb / index finger switching fittings,
gear changes are achieved by:
"Thumb switch" – operation by pressing in
the direction of travel with the thumb
"Index finger switch" – operation normally
by pulling in the opposite direction to travel
with the index finger (alternatively can also
be operated with the thumb by pressing
against the direction of travel).
Figure 15: Operation using the thumb / index finger
switching fittings
Figure 16: Shifting using the thumb / index finger
switching fittings
Operation of the chain shift is also possible
using a grip shift (optional). Here, you can
change between the 3 chain wheels by turning
the left-hand twist grip. On the right-hand grip,
you can change between the sprockets in the
9-speed cassette. You can read the respective
gears on the twist grip.
Figure 17: Shifting using the twist grip
When driving up a hill, it should be noted
that it is only possible to change using the 9speed cassette under heavy loads on the
chain. Changing using the top three chain
wheels is no longer possible if there is heavy
tension on the chain. It is therefore important to
switch to a lower gear as a precaution.

Try to avoid selecting cross gears, as the
efficiency and service life of the chain will fall
significantly (more information can be found in
chapter 26).
For more information, please see the instructions provided by the gear manufacturer.
16.4.2 Hub gears
The hub drive can be changed while driving
and also when stationary. No crank movement
is needed to change and only a small reduction
in torque is needed.
The Rohloff hub drive and Shimano Nexus hub
drives are operated by turning the grip shift.
The gear selected is shown in the display on
the control panel.
Figure 18: Shifting using the grip shift on the Rohloff
"Speedhub 500/14" 14-speed hub drive
Figure 19: Shifting using the grip shift for the Shimano "Nexus" 8-speed hub drive
With the Shimano Nexus hub drives there is
another operation option via the operating
machine that enables shifting using the chin
(option). To change up move the gear lever
45° up and to change down move it 45° down.
After completing the gear change, the gear
lever moves back to its starting position.
Figure 20: Shifting via the PRO ACTIV operating
machine with the Shimano "Nexus"
The Shimano Alfine hub drive is shifted via a
thumb-forefinger switch fitting. The shifting
is achieved as follows:
"Thumb switch" – operation by pressing in
the direction of travel with the thumb
"Index finger switch" – operation normally
by pulling in the opposite direction to travel
with the index finger (alternatively can also
be operated with the thumb by pressing
against the direction of travel).

16.4.3 Pedal bearing gearshift
The pedal bearing gearshift is switched on by
pressing the control buttons on the left and
right of the pedal bearing. Here, you can
choose between a 1:1 gear ratio (the left control button in the direction of travel) or a 2.5:1
gear ratio (the right control button in the direction of travel).
Figure 22: Control button on the pedal bearing
gearshift
The pedal bearing gearshift should be lubricated once or twice a year with the supplied
original semi-fluid grease using the syringe.
The semi-fluid grease is filled through the slotted screw.

16.5 Disc and rim brakes
Normally there is one disc and one rim brake
fitted to the product. Where possible, both
brakes should be operated simultaneously and
the braking requirement reduced by driving in a
way that anticipates the requirement to reduce
speed if necessary.
The brakes are operated using the brake lever.

Figure 25: Brake lever
In the event of abrupt hard braking, there
is a risk that you might fall forward with your
upper body and thereby cause injuries to yourself.
Please make sure that the braking surfaces on the rim, the brake disks and the brake
pads on the rim breaks do not come into contact with oils or greases which could otherwise
impair the braking effect. If rims or brake pads
do come into contact with oils or greases, the
brake pads must be replaced and the brake
disc and rim must be professionally cleaned
with brake cleaner (e.g. Weicon surface
cleaner).
You can find further information in the brake
manufacturer's instructions.
16.6 Back-pedal brake for hub drives
A back-pedal brake is already integrated into
the Shimano Nexus 7 and 8 speed hub drives.
This brake is operated by moving the cranks
against the acceleration direction (clockwise).
The brake force applied is adjusted by the
strength of the backwards movement of the
cranks.
16.7 PRO ACTIV back-pedal brake &
crank release function
16.7.1 Operation
The PRO ACTIV back-pedal brake can be
used for chain gears or hub drives with a freewheel.
The PRO ACTIV back-pedal brake is a closed
hydraulic system consisting of a generator unit
and a disc brake calliper. The system has
automatic wear compensation for the brake
pads.
To adapt the system to your body weight and
the physical limitations of the driver, the
springs of the system are available in three
strengths. These can also be replaced retrospectively.
The back-pedal brake is delivered with a crank
release function which allows reverse driving
and manoeuvring via the hand rims. For functional reasons, the back-pedal brake always
acts as soon as the product moves backwards.
Therefore, the driver must first unlock the reverse movement by operating the crank release function.
The braking function via the backward movement (crank movement against the direction of
acceleration) is always guaranteed – with the
crank release function activated or deactivated.
The crank release function can also be
selected in combination with the 7 and 8 speed
Shimano Nexus hub drives (which already
have back-pedal brakes) so that it is possible
to reverse and manoeuvre via the hand rims.
The back-pedal brake is implemented here via
the hub drive. In this case it must be ensured
that the hub drive's back-pedal brake is not
operational when the crank release function is
activated. If you want to brake with the activated crank release function, this is only possible via the additional braking system such as a
rim brake.

Figure 26: Generator unit PRO ACTIV back-pedal
brake
16.7.2 Operation
The brake is operated by moving the cranks
against the acceleration direction (clockwise).
The brake force applied is adjusted by the
strength of the backwards movement of the
cranks.
The crank release function is operated by
pressing the side pressure plate. To activate
the crank release function, the left-hand pressure plate must be operated (seen from the
direction of travel). To return to normal driving
operation with the back-pedal brake, the righthand pressure plate must be operated.
Figure 27: Left- and right-hand pressure plates
16.7.3 Safety instructions
Before every trip, perform a brake test
while stationary by moving the cranks with the
normal operating force rearwards. The drive
wheel must not be able to move when the system is operated.
At regular intervals, check that all of the
connections, lines, bleed screws and the surface of the transmitter unit do not leak and that
all the screw connections on the brake system
are tightened securely.
At regular intervals, check that the brake
pads and discs are free from grease, oil or
other contamination. In addition, check the
thickness of the brake disc. The minimum
thickness is printed on the brake disc. In addition, the brake pad thickness must be checked
with a measuring calliper. The minimum pad
thickness plus support material is 2.5 mm.
Measure the pad thickness at the thinnest
point.
Do not drive if your product is faulty in one of
the previously listed points. Contact your
dealer immediately who will arrange maintenance by PRO ACTIV.
16.8 Parking brake
Using the aluminium bracket which is attached
to the left-hand side of the pedal bearing support, one of the two brakes can be used as a
parking brake. For this purpose, the aluminium
bracket is clamped over the grip and the brake
lever while the brake lever is depressed.
