About these instructions
Read these operating instructions before
commissioning the bic
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
arise during maintenance, servicing and repairs on the
bicycle. Information for specialist staff does not require
technical laypersons to take any action.

3 Safety
3.1 Requirements for the rider
The physical and mental abilities of the rider must be
sufficient for riding on public roads. The legal
guardians hold sole responsibility for determining
whether minors are suitable to use the bicycle.
3.2 Personal protective equipment
We recommend that you wear a suitable safety
helmet. We also recommend that you wear typical,
close-fitting cycling clothing and sturdy footwear.
3.3 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.
20
The general laws and the regulations for the
prevention of accidents and environmental protection
in the respective country 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.
Page 23
3.3.1 City and trekking bicycle
City and trekking bicycles are designed for daily,
comfortable use on asphalted roads and paths. They
are suitable for riding on public roads.
City and trekking bicycles are not sports bicycles. If
used for sports, reduced riding stability and diminished
comfort are to be expected. City and trekking bicycles
are not suitable for riding off-road.
3.3.2 Mountain bike
A mountain bike is designed for sporting use on
asphalted and non-asphalted paths. The design
characteristics thus include a short wheelbase, a
sitting position with the rider inclined towards the front,
and a brake requiring low actuation force.
The strain on the rider, in particular the hands and
wrists, arms, shoulders, neck and back, is accordingly
high. Inexperienced riders tend to brake excessively
and lose control as a result. A mountain bike is a piece
of sporting equipment. It requires an adaptation period
as well as physical fitness. Use requires the
appropriate training; in particular riding in bends and
braking should be practised.
Safety
21
Page 24
Safety
3.4 Improper use
Failure to adhere to the proper use causes a risk of
personal injury and material damage. The bicycle is
not suitable for the following uses:
• riding with a damaged or incomplete bicycle,
• riding over steps,
• riding through deep water,
• lending the bicycle to untrained riders,
• carrying further passengers,
• riding with excessive luggage,
• riding with no hands,
• riding on ice and snow,
• improper servicing,
• improper repair,
• demanding areas of use, such as professional
competition, and
• stunt riding or acrobatics.
3.5 Personal protective equipment
We recommend that you wear a suitable safety
helmet. We also recommend that you wear typical,
close-fitting cycling clothing and sturdy footwear.
22
Page 25
3.6 Duty of care
The safety of the bicycle can only be assured if all the
necessary measures are taken.
3.6.1 User
The user has the duty of care and responsibility for
scheduling these measures and checking that they are
implemented.
The user:
• makes these operating instructions available to the
rider for the duration of use of the bicycle. If
necessary, he translates the operating instructions
into a language which the rider understands.
• familiarises the rider with the functions of the bicycle
before the first ride. Only riders who have received
instruction must be allowed to ride the bicycle.
• instructs the rider on proper use and the wearing of
personal protective equipment.
• employs specialist staff only for maintenance and
repair of the bicycle.
Safety
The printed EC declaration of conformity in the
appendix is valid as long as the bicycle remains in
original condition. As soon as the user makes any
relevant modifications or additions, he legally
becomes the manufacturer. He must independently
guarantee compliance with the EC directives again in
order to:
• circulate the bicycle again,
• apply the CE marking and
• avoid compromising occupational safety.
23
Page 26
Safety
3.6.2 Rider
The rider:
• receives instruction before the first ride. He/she can
clarify any questions relating to the operating
instructions with the user or the BULLS specialist
dealer.
• wears personal protective equipment.
• assumes all the responsibilities of the user when
ridding the bicycle.

4.3.1 Valve
Each wheel has a valve. It is used to fill the tyre with
air. There is a valve cap on each valve. The screw-on
valve cap keeps out dust and dirt.
The bicycle either has a classical Dunlop valve, a
Presta valve or a Schrader valve.

Description
4.3.2 Suspension
A suspension fork has two functions which improve the
floor contact and the comfort: the suspension and the
damping.
Figure 5:
Bicycle without suspension (rebound) (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
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

Electric drive system
The bicycle is driven by muscle power via the chain
drive. The force which is applied by pedaling in the
direction of travel, drives the front chain ring. The
chain transmits the force onto the cassette and then
onto the rear wheel.

• a charger which is designed for this battery.
As soon as the required muscle
power from the rider
pedaling passes a certain level, the motor is activated
gently and assists the pedaling motion of the rider.
The motor force is determined by the set level of
assistance.

Page 35
Description
4.5.1
The bicycle does not have a s
eparate emergency stop
or emergency shut-off button.
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 can be 3.75 mph here. The drive
stops when the plus button is released.
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.

loaded pannier rack, in particular when steering and
braking. This can lead to a loss of control. This may
result in a crash and injuries.
You should practice how to use a loaded pannier
rack safely and reliably before using the bicycle in
public spaces.
Crash caused by unsecured luggage
Loose or unsecured objects on the pannier rack, e.g.
belts, may become caught in the rear wheel. This may
result in a crash and injuries.
Objects which are fastened to the pannier rack may
cover the bicycle's reflectors and the running light. The
bicycle may be overseen on public roads. This may
result in a crash and injuries.
68
Secure any objects which are attached to the
pannier rack sufficiently.
Objects fastened to the pannier rack must never
cover the reflectors, the lamp or the rear light.
Crushing the fingers in the spring flap
The spring flap on the pannier rack operates with a high
clamping force. There is a risk of crushing the fingers.
Never allow the spring flap to snap shut in an
uncontrolled manner.
Be careful where you position your fingers when
closing the spring flap.

closely. Never reset the rear derailleur protective
function if the rear derailleur is bent, broken or
damaged.
The bicycle has a rear derailleur protective function to
protect the gear shift in case of crashes. The rear
derailleur protective function is triggered if the bicycle
is exposed to a severe impact. The rear derailleur
protective function briefly breaks the connection
between the motor and the chain link. This renders the
rear derailleur inoperable.

7.8 Brakes
Crash caused by incorrect use
Handling the brake improperly can lead to loss of
control or crashes, which may result in injuries.
Practise braking and emergency braking before the
bicycle is used in public spaces.
Shift your weight back and down as far as possible.
Crash caused by wet conditions
The tyres may slip on wet roads. In wet conditions you
must also expect a longer braking distance. The
braking sensation differs from the usual sensation.
This can cause loss of control or a crash, which may
result in injuries.
Ride slowly and brake in good time.
Crash after cleaning, servicing or repair
After cleaning, servicing or repairing the bicycle, the
braking effect may be temporarily unusually weak. This
may result in a crash and injuries.
86
After cleaning, servicing or repair, carry out a few
test brake applications.
Burns caused by heated brake
The brakes may become very hot during operation.
There is a risk of burns in case of contact.
Never touch the components of the brake directly
after the ride.
Page 89
The drive force of the motor is shut off during the ride
as soon as the rider no longer pedals. The drive
system does not switch off when braking.
In order to achieve optimum braking results, do not
pedal while braking.

7.9 Suspension and damping
7.9.1 Locking the front wheel suspension
(Alternative equipment)
When the fork lock is in the open position, the
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.
