MAINTENANCE, CARE AND STORAGE OF STROLLER/BABY BUGGY
A. Maintenance of the bike hitch
- Before each ride make sure that the hitch and safety strap are connected properly.
- Regularly check that the hitch is not damaged, broken, etc. Replace it in the case of the first sign of damage.
- Any damage/break of any part of the xRover stroller/baby buggy should be repaired/replaced immediately to prevent
any personal injuries.
B. Care for the covering/hood
– Your xRover stroller is made of a durable, strong, waterproof fabric – Kortexin™ or Cordura™. Clean the covering only
with ordinary soap or a mild cleaner and warm water. Let air dry.
C. Wheels and central axes
- We recommend having the wheels (rear 20” and front 14”) checked by a standard bicycle repair shop at least twice a
year. For safety reasons, make sure that the wheel spokes or central axis are not loose before each use of the
stroller/baby buggy.
D. Wheel frame and mounting
– Regularly check that all nuts and bolts are tightened properly.
E. Storage
– Store the stroller/baby buggy in a dry and well-ventilated place. Before storing, make sure that the stroller/baby buggy
is dry; this will prevent it from becoming mouldy. If the stroller is not in use, protect it against sunshine; this will prevent
it from discolouring. Do not store the stroller coupled to the bike.
Check all parts of your stroller/baby buggy before each use!
NOTICE
SAFETY INSTRUCTIONS
Important rules for safe use of your xRover stroller/baby buggy.
1. Read carefully all instructions before using the stroller/baby buggy! Incorrect understanding and
failure to follow these instructions may lead to an otherwise avoidable accident at which you and/or
your passengers may sustain a serious or fatal injury.
2. Safe and correct use of this product is your responsibility! Before using your stroller/baby buggy,
take a trial bike ride, go for a walk or run or hike with the stroller loaded (to more than the expected
weight of passengers with load) to assure that you will handle the loaded stroller/baby buggy during
each of these activities. Be extremely careful when operating the stroller/baby buggy off roads. Apart
from the safe ride principles, always follow the rules stated below.
3. Make sure that your bike is in good operating condition. We recommend carrying out regular safety
checks by a certified bicycle mechanic.
NOTICE
The colours of the covering
and other parts of the
stroller/baby buggy may
change due to the weather,
sunlight and atmospheric
exposure!

4. Do not modify the stroller and bike. If you are not sure whether your bike is compatible with the
stroller, contact the manufacturer – Volter s.r.o.
5. Transported persons must be fixed appropriately in relation to their age, handicap or physical needs.
If required, the manufacturer can modify the stroller according to passengers’ individual needs.
6. Do not exceed the maximum allowable loads of strollers/baby buggies – this applies to each model
separately, see page 5, Technical data. This weight is the highest allowable load capacity of the seat
including load. Objects transported in the stroller/baby buggy must be properly fixed to prevent them
from moving during ride. An unstable load and overloading cause worsening of the stability and driving
of the stroller/baby buggy.
7. Always safely and firmly fasten the straps around the shoulders, waist and crotch of the passengers.
Regularly check the position of the shoulder strap. Make sure that passengers cannot put their fingers
in the wheel spokes. Passengers must not jump, swing and lean in the stroller/baby buggy.
8. Keep an eye on the passengers in the stroller/baby buggy at all times.
9. For a smooth ride, keep the tyre-tubes of the stroller/baby buggy inflated to the recommended
pressure shown on the tyre side or on page 5, Technical data. Check the pressure in the tyre-tubes
before each use. Over-inflated tyre-tubes may break and cause an accident of the stroller/baby buggy.
Under-inflated tyre-tubes wear significantly and change the driving properties of the stroller/baby
buggy.
10. Only use the stroller with motor-less bicycles capable to tow the extra weight of the stroller/baby
buggy with a passenger. Do not use the stroller with electric bikes, motorcycles, mopeds, cars, and any
other motor vehicles. Check in the instructions for your bike or with the vendor that your bicycle is
compatible with the stroller.
11. Do not use a stand or any other parking aid to support your bike with the coupled stroller. The
coupled stroller may change the bicycle balance and cause that the stand is non-functional. In a fall,
the bike and the stroller/baby buggy could be damaged.
12. Always use the flag provided with the cycling set to increase your visibility.
Do not presume your right of way. Do not use your stroller/baby buggy in areas with heavy traffic such
as busy streets or in any places where riding the stroller/baby buggy could be unsafe.
13. Avoid riding at night. Your ability to see and to be seen is impaired considerably. If you have to ride
at night, use the appropriate lighting on your bike and wear bright reflective clothing. The stroller/baby
buggy is equipped with many reflective elements.
14. Both the cyclist and passengers should wear approved bicycle helmets.
15. When riding the stroller on public roads, always follow all traffic regulations and use the correct
signalling. You are obliged to follow the Road Traffic Act (Act No. 361/2000 Coll., on road traffic).
16. Every time you stop the stroller/baby buggy, secure it against movement by applying the
handbrake, see page 20, Chapter 3.
17. Always use the protective mosquito net when using as a bicycle stroller, see Chapter 9.2.
WARNING!
Bicycle strollers could overturn and cause a serious injury to the passenger/cyclist.
An obstacle crash of the bike could cause an overturn of the stroller/baby buggy at the minimum speed.

1. Assembly and disassembly of the stroller/baby buggy
The stroller uses quick-acting components so both its assembly and disassembly can be performed in a few dozens of
seconds.
1.1 Rear axle
The rear wheels are fixed using quick-acting half-axles. By pressing the cap on one end of the axle the lock on the
opposite side is released and the axle can be slid in/out the rear wheel hub.
Figure 2
1.1.1 Assembly
is to be started by inserting the half-axle in the rear wheel hub – slide the axle fully in the rear
wheel hub.
Figure 3 Figure 4
A – press the cap to unlock the lock and B – slide the axle in to rear axle block.

Insert the assembly fully into the block, release the cap and make sure that the wheel is secured in the block safely.
Figure 7
Use the same procedure to install the other rear axle wheel. Both rear wheels are fully interchangeable; if you have a
cyclocomputer installed, the wheel with the magnet must be installed on the left-hand side (when looking from the back).
Figure 8

1.1.2 Disassembly is to be performed in reversed order; A – grasp the rear wheel at the central hub, B – press the
half-axle cap and C – fully release the wheel by pulling.
Figure 9
For the subsequent transport, both dismantled rear wheels can be jointed together using one half-axle; keep the other
half-axle carefully not to lose it, preferably in one of the storage bags on the stroller/baby buggy.

1.2 Front axle
The front wheels with forks are fixed to the stroller/baby buggy with quick-acting clamps. Loosen the lever to unlock the
clamp, tighten it to lock the clamp; locking can be regulated by tightening or loosening the nut on the opposite end of
the bolt. Handle the nut only by hand when the clamp is unlocked.
The front axle assembly contains six quick-acting clamps; the two horizontal ones serve for fixing the fork with the front
wheel, the inner vertical pair serves for adjusting the fork tilt and the outer vertical pair serves for fixing and adjusting
the cross tube of the front axle. Additional towing devices can be fixed to the outer ends of this tube.
The whole assembly is delivered in assembled and adjusted state; the owner only fixes the selected front wheel with fork
and adjusts the required fork tilt.
Figure 11
1.2.1 Assembly of the front fork with wheel
Loosen both horizontal clamps on the front axle block and slide the fork extension in the hole in the block. The clamps
are fixed to the block also in loosened state with the mount engaged in the block slot. This prevents the clamp from
slipping off or losing. The clamp can only be removed from the block using a special tool.

Turn the extension in the hole so that the pin (protruding dowel screw, Fig. 13 and Fig. 14, point 2) engages in the
recess in the front axle block and fully slide the extension in the block.
Figure 13 Figure 14
Turn both horizontal clamps to the appropriate position so that the levers do not collide with the levers of vertical clamps.
Lock both horizontal quick-acting clamps.
1.2.2 Disassembly of the front fork with wheel
Loosen both horizontal quick-acting clamps (Fig. 11, point 3) and (Fig. 12).
Take the front fork extension out of the front axle block.
1.2.3 Removing the front wheel from the fork
The 14” front wheel is fixed to the fork with a quick-acting axle. For transport or service reasons, it may be necessary to
remove the wheel from the fork.
Figure 14 LOCKED Figure 15 RELEASED
Loosen the lever of the quick-acting axle. The axle ends engage in the recess in the fork, so even if the lever loosens
accidentally during ride, the wheel will not fall out of the fork.

15
To loosen the wheel it is also necessary to loosen the nut on the opposite side of the axle by a few turns. The wheel can
then be removed from the fork. The place for storing this wheel with fork is in the rear pocket of the rear bag on the
stroller/baby buggy.
Figure 16 Figure 17
Perform assembly in reverse order.
The 6” wheel is fixed in the fork with an Allen head bolt with nut which serves also as the axle. If necessary, this bolt can
be loosened and the wheel removed.
2. Adjusting the required alignment of the stroller/baby buggy
Select the required front wheel and fix it along with the fork to the front axle block (for the procedure see above). The
block is symmetrical, it can be used from both sides if necessary.
Loosen the inner pair of vertical quick-acting clamps on the front axle.
Turn the wheel with fork to the required position. The tilt of the whole stroller/baby buggy can be changed by selecting
the wheel size and turning the fork. In this way the maximum comfort of the transported person can be ensured.
Turn the inner pair of vertical quick-acting clamps so that their levers do not collide with the vertical clamps.
Lock the levers of the inner pair of vertical quick-acting clamps. The front block is now firmly fixed to the cross axis of the
front axle.
The 6” front wheel can be positioned in the following range:
Figure 18

16
The 14” front wheel can be fixed in the following range:
Figure 19 – stroller seat tilt: 1 – sitting position; 2 – lying position
The alignment of the rear axle must be adapted to the set tilt of the stroller/baby buggy to compensate for the possible
toe-in or toe-out of the rear wheels. The wrong alignment causes an increased exertion and an increased wear of the
rear wheel tyres; in addition, an asymmetrical adjustment could cause slide-slipping when moving forwards or other
problems with the traction of the stroller/baby buggy.
Place the stroller on a hard level surface.
The rear axle block is fixed with a quick-acting clamping bolt on the axle. Loosen the clamping bolt lever.
Figure 20

17
Turn the block with the brake on the rear axle in such a way that the bubble in the built-in spirit level is between the
marks. The spirit level is on the top of the block behind the brake carrier and is best accessible when looking from the
back of the stroller/baby buggy.
Owing to precise manufacturing tolerances, it is relatively hard to turn the rear axle block even with the quick-acting
clamping bolt loosened; when the lever is locked, the block is then fixed on the axle firmly and reliably.
When checking the block position setting, the stroller must stand stably on all three wheels.
1 – rear axle block/hub lock release
2 – rear axle block trimming
Figure 21
Obrázek 22
After the block is set to the correct position, lock again the lever of the quick-acting clamping bolt.
Repeat the same procedure with the other wheel.
Finally, recheck the alignment according to the spirit levels on the left and right blocks. The correct alignment is a
guarantee of excellent driving properties of the stroller/baby buggy.

3. Brake adjustment
Both drum brakes are operated simultaneously with one double brake lever; its locking pin enables you to use the brake
also as a parking brake. The brake lever is located on the handle of the stroller/baby buggy. Adjustment of the same
effect of both brakes is very important to maintain the straight travel direction of the stroller/baby buggy when braking.
Due
to long-term use, the cable lengths change and it is necessary from time to time to adjust the brakes individually to the
same braking action on both wheels. Significantly worn cables must be replaced.
The basic adjustment is performed with the clamp bolt with nut on the brake moving lever.
1 – Bolt for basic brake adjustment
Figure 23
Fine adjustment can be carried out 1 – with the locking ends on both ends of the outer sheath of the brake line.
Figure 24 Figure 25
The braking action is controlled by the force of pressing the brake lever. Drum brakes provide a wide range of braking
action from gentle braking to adjust speed to strong braking to quickly stop the stroller/baby buggy.
By strongly pressing both the brake lever (Fig. 26, point 1) and the locking pin (Fig. 26, point 2) simultaneously the
brake will be blocked and the stroller is braked continuously (parking brake). This mode prevents the stroller/baby buggy
from starting spontaneously.
By strongly pressing the brake lever (Fig. 26, point 1) again, the locking pin and thus the whole system is released; after
releasing the brake lever the stroller is fully braked off and can move freely.

19
Figure 26: A – parking brake deactivated; B – parking brake activated
4. Handle
The stroller is equipped with a height adjustable handle. In the area of contact of hands with the handle, it is provided
with foam covering for comfortable handling. To transport the stroller/baby buggy or to use towing devices, the handle
can be folded down fully to lower the outer profile dimensions of the stroller/baby buggy.
The setting can be changed by simultaneously pressing BOTH grey buttons on the sides of the handle joint. The joint has
several fixed positions; after releasing the grey buttons, the handle will be fixed in that position. The handle position does
not affect the brake function.
NOTICE: Due to the possibility to individually adjust the handle position and tilt, this is provided with robust positioning
joints. These joints can have slight clearances in individual fixed positions in both motion directions. This clearance is not
a production defect and does not prevent the stroller/baby buggy from operating at full load.
NOTICE
When you stop the stroller in
traffic, always ensure that it is
braked correctly! Especially
when there are passengers in
it and you leave the stroller
without direct attendance and
without the strap fixed on your
wrist.

20
Figure 27
5. Hood
The stroller is equipped with a removable hood to increase the comfort of transported persons and their protection
against adverse environmental effects (rain, wind, snow, sunshine, etc.).
The hood frame shape can be adjusted; the shape can be changed by simply pressing by hand in the required direction.
Figure 28
The hood can be removed completely; this is done by simultaneously pressing the red button on the side of the hood
joint and pulling the frame upwards in the direction of the guide rail.
Figure 29
Remounting the hood is done by placing the joint in the rail lead and moving the frame downwards until the red lock
engages in the rail recess. Jumping-out of the red button indicates that the limit position has been reached and that the
joint is locked in this position.
Mounting of the hood is easier when it is folded up. It is important that the cloth covering of the hood is mounted from
the rear of the upper arch of the frame of the stroller/baby buggy and before it is unfolded the covering position is
adjusted so that the covering can be stretched correctly.
