Safety
Proper use
City and folding bikes serve to transport a single person on paved roads
and paths in public road traffic. In this connection, the tyres must be in
constant contact with the ground. They are for private use. The safety
equipment required pursuant to the German Road Traffic Act (StVZO)
must be present and is usually included. Any other use is not considered
to be proper use.
City and folding bikes are not suitable for the following:
jumps
riding on stairs
riding through deep water
participation in sports events
Mountain bikes serve to transport a single person. Due to the fact that
safety equipment is usually not necessary for mountain bikes according
to the German Road Traffic Act (StVZO), they are intended for use away
from public roads.
Mountain bikes are not suitable for the following:
jumps
wheelies
stunts
downhill
riding on stairs
riding through deep water
participation in sports events
Proper use also includes compliance with the recommended
maintenance intervals as well as reading and understanding this manual.

Basic safety instructions
Prevent serious injuries or death from mechanical defects and
handling the bike incorrectly
Bike riding can lead to serious injuries or death from mechanical defects
or incorrect handling of the bike.
Always perform a safety test before riding your bike (see the Riding
the bike section starting on page 86).
Familiarise yourself with the brakes, pedals and changing gears
before the trip.
Always ride at a speed that corresponds to the riding conditions.
Prevent electric shock or explosion from improper handling of
the battery and charger
Handling the battery and charger incorrectly can lead to an electric
shock or explosion. A serious injury or death may be the consequence.
Only use the battery included with the delivery.
Never connect the positive terminal of the battery to the negative
terminal.
Protect the battery from direct sunlight.
Do not disassemble and clean the battery.
Only use the charger included with the delivery for charging the
battery.
Only use the charger indoors.
The connector of the charger is the cut-off device from the power
grid. Make sure that the power outlet is close to the charger and is
easily accessible.
Only use the charger with an earthed 230 V power outlet.
Keep the metal contacts clean, or clean them with a soft and dry
cloth if necessary.
Do not charge a battery with visible damage, e.g. a broken housing.
Never put a battery with visible damage, e.g. a broken housing, into
operation.

Safety
11
Never let the battery fall.
Charge the battery in a temperature range between 10° and 30°.
Make sure that the charger is only used by persons without any
limited physical, sensory or mental capabilities.
Prevent fire or explosion
A short circuit can be caused by moisture, electrically conductive soiling
or mechanical damage. The consequence may be the battery catching
fire or exploding.
Clean the electric motor and control unit exclusively from the outside
with a damp sponge. Never use a high-pressure cleaner.
If these components are accidently completely submerged in water,
disconnect the motor from the battery immediately and do not put it
back into operation again before having it checked by the
manufacturer.
Prevent serious injuries from body parts coming into contact
with components of the bike
When riding, parts of the body or other objects can come into contact
with the teeth of the sprockets, the moving chains, turning pedals and
crank arms as well as the turning wheels of the bike. A serious injury
may be the consequence.
When riding, make sure that parts of your body do not come into
contact with the components of the bike mentioned above.

Safety
12
Prevent serious injuries from damaged components
When riding off-road or over kerbs, the electric motor, crank arms or the
bottom bracket can be hit and damaged. A serious injury may be the
consequence.
Only use the bike on approved paths.
In the event of obstacles, dismount and lift up the bike.
In the event of damage, have the bike checked by a specialist dealer.
Prevent serious injuries or death during wet weather
Wet weather adversely affects road holding, braking behaviour and
vision, both for bike riders as well as other road users. The braking
power of your brakes is reduced considerably in wet weather (as well as
the brakes of all other road users). In addition, tyre treads do not grip
anywhere as good as they do on dry roads. This hampers speed control
and increases the risk of losing control over the bike. Serious injuries or
death may be the consequence.
Always ride slowly in wet weather.
Always brake proactively and carefully in wet weather.
Switch off the electric motor or ride carefully with the lowest motor
assist.
Prevent serious injuries or death at twilight or in the night
Riding at night and at twilight is more dangerous than during the day. It
is hard for other road users to see bike riders, and therefore this can
result in serious injuries or death.
Avoid riding at night and at twilight.
Always ride slowly.
Always ride with bike lights and reflectors.

Safety
13
Always avoid dark areas and areas with heavy or fast traffic.
Always avoid road obstacles.
If possible, ride on familiar routes.
Prevent serious injuries or death from damaged, bent or loose
reflectors and lights
The bike’s reflectors capture and reflect the light from streetlights and
car headlights so that you are recognised as a cyclist. Damaged, bent or
loose reflectors can result in you not been seen clearly by other road
users. Serious injuries or death may be the consequence.
Check reflectors and their mounting regularly.
Have damaged, bent or loose reflectors replaced by your specialist
dealer.
Prevent serious Injury when riding off-road or over kerb edges
Riding off-road or over kerb edges without adjusting your speed can
result in a fall. A serious injury or death may be the consequence.
Always ride at a speed that corresponds to the prevailing conditions.

Safety
14
Prevent serious injuries or death from replacement of
components or adding accessories
There are numerous components and accessories available that can
improve the comfort, performance and appearance of the bike. These
components or accessories are added at your own responsibility. It can
be that these components or accessories have not been tested by the
bike manufacturer for compatibility, reliability or safety. Unconfirmed
compatibility, reliability or safety as well as improper installation, use and
maintenance of components or accessories of the bike can lead to
serious injuries or even death.
Always contact your specialist dealer before the installation, use and
maintenance of the components.
Always read and follow the instructions for use included with the
accessories.
Prevent serious injury from incorrect maintenance, care and
cleaning
Incorrect maintenance, care and cleaning can lead to injuries or even
death.
Only perform the activities given in the maintenance plan.
Only use commercial lubricants and cleaning agents.
Have other maintenance work as well as repairs carried out by a
qualified specialist dealer.

Safety
15
Prevent serious injuries or death from damaged components
The bike and its components are subject to wear (scratches, cracks,
fraying) and tear. A damaged component can suddenly and immediately
malfunction, which can lead to injuries and even to death.
Check the components (e.g. brake pads, tyres, etc.) regularly for
wear and tear.
Replace them (if possible) or have the damaged components of the
bike repaired by a qualified specialist dealer.
Prevent breathing difficulties and choking
When new, the materials that are used (e.g. paint) give off vapours as
does the electric motor when the temperature is too high. The vapours
can become concentrated when storing the bike in closed rooms.
Breathing difficulties or choking can be the consequence.
Always store your bike in a well-ventilated room.
Prevent burns
Components of the bike (e.g. brakes, wheels, etc.) can become hot
when riding. Touching these components can cause burns.
Allow all hot components to cool down before any activities on them,
or wear heat-resistant safety gloves.
Prevent injuries to your legs
Injuries can occur to your legs from too small of a distance between
pedals (Q Factor). There is a risk that the rider will have problems with
the installed crank arm set.
In this case, have your bike modified by a specialist dealer.

Safety
16
Prevent vibrations
The electric motor might not run smoothly as a result of incorrect
assembly, wear and overloading (e.g. the electric motor hitting when
riding over bumps, ridges) or from detached parts.
Only use the bike on approved paths.
Before each bike ride, check the drive unit to make sure it runs
smoothly and without any play.
In the event of creaking, grinding noises or obvious damage, go to a
specialist dealer and have the bike repaired.
When using the bike on a road or also off-road, vibrations from the
surface you are riding on will be passed on to your body.
Only use the bike on approved paths.
Prevent disorders
Sitting on the saddle frequently and for long periods of time can result in
disorders of the prostate for men.
Install (if necessary) a saddle that is ergonomically suitable for
females/males.
Take precautions if applicable.
Prevent dehydration from cycling
Cycling is a strenuous physical activity.
Always make sure you have a sufficient supply of liquids.
Prevent freezing
Freezing can occur when cycling in cool and cold temperatures.
Always be sure to wear suitable clothing, including face protection, in
the event of cool or cold temperatures.

Safety
17
Prevent falling from a suddenly occurring electric motor assist
A suddenly occurring electric motor assist results in the risk of losing
control and thereby falling.
Always test the electric motor assist before the first ride.
Always wear personal protective equipment (PPE).
Prevent poisoning
Material or vapours can leak out of damaged components of the bike
(e.g. batteries, electric or electronic components). Poisoning of the
environment may be the consequence.
Dispose of used batteries and electric or electronic components of
the bike according to legal requirements.
Observe the specifications of the manufacturer of these products in
this connection.
Prevent property damage
Improper handling of the battery can lead to property damage.
Make sure that the battery is not completely discharged (total
discharge).
Only store the battery at a dry location with low air humidity.
Make sure that the stored battery is charged at least every six
months.
