About these instructions
Read these operating instructions before
commissioning the bicycle in order to use all the
functions correctly and safely. They are not a
substitute for personal training by the BULLS
specialist dealer. The operating instructions are a
component part of the bicycle. Therefore, if it is resold at a later time, they must be handed over to the
subsequent owner.
These operating instructions are mainly directed
towards the rider and user of the bicycle. In general,
they are technical laypersons.
Text passages which are directed expressly at
specialist staff (e.g. bicycle mechanics), are clearly
marked with a blue tool symbol.
Staff at all BULLS specialist dealers have specialist
training and qualifications, and are therefore capable
of identifying risks and preventing hazards which may
arise during maintenance, servicing and repairs on the
bicycle. Information for specialist staff does not require
technical laypersons to take any action.

3.1
Requirements for the rider
If there are no legal requirements for the rider of
electrically power assisted cycles, we recommend that
the rider should be a minimum 15 years of age and
have experience with muscle-powered bicycles.
The physical and mental abilities of the rider must be
sufficient for the use of a muscle-powered bicycle.
If the bicycle is used by minors, as well as thorough
instruction to be provided by or in the presence of the
legal guardians, supervised use should also be
scheduled until there is certainty that the bicycle is
being used in accordance with these operating
instructions. The legal guardians hold sole
responsibility for determining whether minors are
suitable to use the bicycle.
3.2
Proper use
The bicycle must only be used in perfect, fully
functional condition. National requirements may apply
to the bicycle which differ from the standard
equipment. For riding on public roads, some special
regulations apply in relation to running light, reflectors
and other components.
The general laws and the regulations for the
prevention of accidents and environmental protection
in the respective country, state and/or city of use
must be adhered to. Proper use also includes all
instructions for actions and check lists in these
operating instructions. Approved accessories can be
installed by specialist staff.
Each bicycle is assigned to a bicycle type which
determines the proper use.

personal injury and material damage. The bicycle is
not suitable for the following uses:
•
•

Suspension
A suspension fork has two functions which improve the
floor contact and the comfort: the suspension and the
damping.
1
Figure 5:
2
Bicycle without suspension (1) and with suspension (2) when
riding over an obstacle
The suspension prevents an impact, e.g. caused by a
stone lying in the way, from being directed directly into
the rider's body via a fork. Instead, it is absorbed by the
suspension system. This causes the suspension fork
to compress. The compression can be disabled so that
a suspension fork reacts like a rigid fork.
The compressed suspension fork then returns to its
original position. The damper decelerates the
movement and thus prevents the suspension system
from springing back in an uncontrolled manner, and
the fork from oscillating up and down.
Dampers which dampen the compressive deflection
movements, i.e. the compression load, are called
compression dampers or dashpots.

BULLS_BOSCH_Purion_BBC Page 36
Description
The bicycle does not have a separate EMERGENCY
STOP or EMERGENCY SHUT-OFF button. The drive
system with removable display can be stopped in case
of emergency by removing the display.
The motor switches off automatically as soon as the
rider no longer pedals, the temperature is outside the
permitted range, there is an overload or the shut-off
speed limit has been reached.
A pushing aid can be activated. The pushing aid
continues to drive the bicycle as long as the rider
pushes the plus button on the handlebars. The
maximum speed in the process is 3.75 mph. The
drive stops when the plus button is released.
4.5.1
Battery
The lithium ion battery has an internal electronic
protection circuit. It is matched to the charger and the
bicycle. The temperature of the battery is monitored
constantly. The battery is safeguarded against deep
discharge, overcharging, overheating and short
circuit. In case of a risk the battery is switched off
automatically by a protective circuit. The battery also
switches to sleep mode for self-protection when not
used for a longer period.
The service life of the battery can be extended if it is
well cared for and, above all, stored at the correct
temperatures. Even if the battery is cared for
properly, the charge status of the battery reduces as
it ages. If the operating time is severely shortened
after charging, this is a sign that the battery is spent.

suspension system has activated suspension and thus
provides the rider and the bicycle with relief. Riding
with the fork lock open should therefore be preferred
for everyday riding.
When riding downhill or at high speed, for instance,
the force which is exerted on the drive is absorbed by
the suspension system and reduced by up to 50%. In
these cases it is recommendable to close the
suspension fork.
The fork lock may be situated directly on the fork or on
the handlebars, depending on the version.

Maintenance
The BULLS specialist dealer will advise you on the
choice of right child seat system for the child and the
bicycle. The scope of delivery of commercially
available child seats does not usually contain any of
the material which is required to adapt the bicycle to
the child seat.
Moreover, knowledge, skills and special tools may be
required.
Therefore, the initial installation of a child seat must be
performed by the BULLS specialist dealer in order to
maintain operational and product safety. When
installing a child seat, the BULLS specialist dealer
makes sure that the seat and the fastening mechanism
for the seat suit the bicycle, that all components are
installed and firmly fastened, that shift cables, brake
cables, hydraulic and electrical cables are adjusted
as necessary, that the freedom of movement of the
rider is not restricted, and the permitted total weight

! CAUTION
Bicycle trailer
Crash caused by brake failure
The brake may not work sufficiently if there is an
excessive trailer load. The long braking distance can
cause a crash or an accident and injuries.
 Never exceed the specified trailer load.
NOTICE
 The operating and safety notes for the trailer
system must be observed.
 The legal regulations on use of bicycle trailers must
be observed.
 Only use type approved coupling systems.
A bicycle which is approved for towing a trailer is
equipped with the respective information sign. Only
bicycle trailers with a support load and total mass
which do not exceed the permitted values, must be
used.
The BULLS specialist dealer will advise you on the
choice of right trailer system for the bicycle. The
scope of delivery of commercially available bicycle
trailers does not usually contain any of the material
which is required to adapt the bicycle to the trailer.
Moreover, knowledge, skills and tools which a
technical layperson does not have, may be required.
Therefore, the initial installation of a trailer must be
performed by the BULLS specialist dealer in order to
maintain operational and product safety.

Risk of fire and explosion
! WARNING The safety electronics on damaged or faulty batteries
may fail. The residual voltage can cause a short
circuit. The batteries may self-ignite and explode.
 Remove batteries with external damage from
service immediately and never charge them.
 If the battery becomes deformed or begins to
smoke, keep at a safe distance, disconnect the
power supply at the socket, and notify the fire
service immediately.
 Never extinguish damaged batteries with water or
allow them to come into contact with water.
 Faulty batteries are hazardous goods. Dispose of
faulty batteries properly and as quickly as possible.
 Store in a dry place until disposal. Never store in
the vicinity of flammable substances.
 Never open or repair the battery.
! CAUTION
Chemical burns to the skin and eyes
Liquids and vapours may leak from damaged or faulty
batteries. They can irritate the airways and cause
burns.
 Avoid contact with leaked liquids.
 Immediately consult a doctor in case of contact with
the eyes or any discomfort.
 In case of contact with the skin, rinse off
immediately with water.
 Ventilate the room well.

Recycling and disposal
The bicycle, the battery, the display and the charger
are recyclable materials. They have to be disposed of
separate from the domestic waste in accordance with
the valid legal regulations, and recycled.
Separate collection and recycling saves reserves of
raw materials and ensures that all the regulations for
protection of health and the environment are adhered
to when recycling the product and/or the battery.
u Never dismantle the bicycle, the battery or the
charger for disposal.
u The bicycle, the display, the unopened and
undamaged battery and the charger can be
returned to any BULLS specialist dealer free of
charge. Depending on the region, further disposal
options may be available.
u Store the individual parts of the decommissioned
bicycle in a dry place, free from frost, where they
are protected from direct sunlight.
