1.1 Safety guidelines

WARNING

There is a risk of danger, if the safety instructions are not observed.

Non-observance of safety information and instructions can lead to an electrical
shock, fire and/or serious injuries.

 Please observe all safety information and instructions both in these

and in all other instructions included with the E-Bike.

 CAUTION: Risk of burns from touching the motor casing.
 CAUTION: Risk of injury if the E-Bike system is activated

unintentionally. Please remove the rechargeable battery before
working on the E-Bike (e.g. assembly, maintenance, working on the
chain etc.), or transporting or storing it.

 CAUTION: Risk of injury when using the pushing aid without the

wheels touching the floor. Only use the pushing aid when pushing the
E-Bike.

 CAUTION: Please do not make any changes to your E-Bike. Never try to

increase the performance capability of the E-bike system; otherwise,
you could reduce the service life of the parts and risk damage to the E­Bike system and to the E-Bike. Also, any manipulation of the E-Bike
system will invalidate the guarantee and warranty. Incorrect handling
of the system also poses a risk to your safety and others on the road.
If any unauthorised changes are made to the E-Bike system, there is a
risk of high personal liability costs or even criminal proceedings, if the
accident is a result of the manipulation.

 Observe all national regulations relating to the approval and use of E-

Bikes.

 Never open the motor. This is maintenance-free and may only be

repaired by qualified specialists and only using original spare parts.
This retains the motor safety. If the motor is opened without
authorisation, the warranty becomes invalid.

 All components of the E-Bike system and parts that are mounted to

the motor (e.g. chain wheel, chain wheel bracket, pedals) may only be
replaced with parts approved by the cycle manufacturer. This protects
the motor from damage (e.g. from overloading).

 Read and observe the safety instructions and information in the

operating instructions of the rechargeable battery and in the E-Bike
operating instructions.

 Please keep these instructions for future reference.

1.2 Intended use

The motor is only designed to drive your e-Bike and may not be used for other
purposes.

Page 6 of 28 Version 1.1

1.3 Explanation of the figure

The illustrations are outlines only and details may vary on your E-Bike.

1.4 Operation

For more information about using the E-Bike, please refer to chapter 2.7.

The E-Bike system is only functional when the display is mounted.

1.5 Cycling and advice

The BMZ E-Bike system provides electromotor support to the cyclist in a Pedal
Electric Cycle (Pedelec). The support provided depends on the force applied by the
cyclist onto the pedals. The E-Bike drive only provides support, if the cyclist is
pedaling. This is independent of the support level.

The E-Bike drive switches off automatically at speeds in excess of 25 km/h. If the
speed drops below 25 km/h, the support starts again automatically.

Once exception is the pushing aid function that allows the E-bike to be pushed easily
without turning the pedals at a speed of up to 6 km/h. The pedals may also turn
when the pushing aid is activated.

You can ride the E-Bike like a normal bike at any time by either switching off the E­Bike system or setting the support level to Off (see 2.7.2). The same applies when the
rechargeable battery is empty.

Take some time to familiarise yourself with your E-Bike system before you use it in
normal road traffic. Test the various support levels until you feel safe handling this
product. Before going on longer trips, familiarise yourself with how different
parameters and ambient conditions impact on the range of your E-Bike.

The E-Bike system supports several motor setups. These are set individually for each
bike model in cooperation with the bike manufacturers. You can obtain detailed
information about your E-Bike's motor setup from your cycle manufacturer and your
bicycle dealer.

The range is affected by many factors such as:

Please observe the operating and storage temperature of the E-Bike components.
Protect the motor, display and rechargeable battery from extreme temperatures (e.g.
intensive sunshine without ventilating at the same time). The components
(especially the rechargeable battery) can be damaged by extreme temperatures.

1.6 Maintenance and cleaning

Keep all components of the E-Bike clean, especially the contacts of the rechargeable
battery and its bracket. Clean this carefully with a dry and soft cloth.

None of the components, including the motor, may be dipped into water or cleaned
with a high-pressure device. Please contact an authorised dealer for servicing or
repairs to the E-Bike.

1.7 Inspection

On reaching a mileage of 15,000 km, the drive belt needs to be replaced by a service
centre authorised by BMZ.

You can obtain information about your responsible service centre from your bicycle
dealer.

1.8 Transport

When transporting a complete E-Bike, please note the transport information
pertaining to the rechargeable batteries (see 3.8).

1.9 Waste Disposal

Motor, display, rechargeable battery, speed sensor, accessories and packaging should
be disposed of in an environmentally-compatible manner. Do not dispose of your E­Bike and its components in the household waste system.

In compliance with the European Directive 2012/19/EU electrical devices that are no
longer serviceable, and in compliance with the European Directive 2006/66/EG faulty
or spent rechargeable batteries/batteries, must be collected separately and disposed
of in an environmentally-friendly manner.

3.1 Safety guidelines

WARNING

There is a risk of danger, if the safety instructions are not observed.

Non-observance of safety information and instructions can lead to an electrical
shock, fire and/or serious injuries.

Injuries or damage is also possible as a result of dangerous reactions of chemical
substances that leak from the rechargeable battery resulting from non-observance
of the safety instructions.

 Please observe all safety information and instructions both in these

and in all other instructions included with the E-Bike.

 CAUTION: Risk of injury if the E-Bike system is activated

unintentionally. Before working on the E-Bike (e.g. assembly,
maintenance, working on the chain etc.), or transporting or storing it,
please remove the rechargeable battery from the E-Bike.

 CAUTION: Risk of injury when using the pushing aid without the

wheels touching the floor. Only use the pushing aid when pushing the
E-Bike.

 Risk of short circuits! Do not open, dismantle or chop up the

rechargeable battery. Opening the rechargeable battery will invalidate
the warranty.

 Risk of explosion! Protect the rechargeable battery from heat (e.g. also

from permanent exposure to sunlight), fire and submersion into water.

 Risk of burns and fire caused by short circuits! Keep small metal

objects (e.g. paper clips, nails, screws, keys etc.) away from the
rechargeable battery. These could bridge the contacts. All warranty
claims toward BMZ will become invalid in case of short circuit damage
resulting from this.

 Risk of skin irritation or burns from leaking fluids: if used incorrectly,

fluid can leak from the rechargeable battery. Avoid contact with this.
In case of accidental contact, rinse the affected areas with water. If the
fluid comes into contact with mucous membranes (e.g. eyes), please
seek medical attention immediately.

 Do not expose the rechargeable battery to mechanical impacts. There

is a risk of damage to the rechargeable battery.

 The risk of short circuits and fire or an electrical shock is higher, if a

damaged rechargeable battery is used. Never continue to use a faulty
or damaged rechargeable battery.

 Vapours may irritate the respiratory organs. Vapours may be created if

the rechargeable battery is damaged or used incorrectly. Let in fresh
air and seek medical advice if symptoms persist.

 Risk of fire due to use of other chargers. Only charge the rechargeable

battery with the charger supplied with the E-Bike system.

3 Rechargeable battery

21 Jun 2017 Page 17 of 28

 Only use the rechargeable battery in conjunction with E-Bikes with the

original BMZ E-Bike system. This is the only way to protect the
rechargeable battery from dangerous overloading.

 Risk of injury or risk if other rechargeable batteries are used: only use

rechargeable batteries approved by the bike manufacturer for your E­Bike. The warranty and liability will become invalid if other
rechargeable batteries are used.

 Keep the rechargeable battery away from children.
 Always keep the rechargeable battery dry and clean.
 Always keep the contacts of the rechargeable battery clean. If they are

soiled, clean them with a dry cloth.

 Avoid unnecessary charging. Do not charge the rechargeable battery

for a longer period, if you are not going to use it.

 Please keep these instructions for future reference.
 Never leave the rechargeable battery and charger unattended during

charging.

3.2 Intended use

The rechargeable battery is designed and intended for use in a BMZ E-Bike system.

The battery must only be used with bikes/components in compliance with the bike
categories 1 and 2 according to the international standard (ASTM F2043-13 Standard
Classification for Bicycle Usage):

 Category 1: This is a set of conditions for the operation of a

bicycle/component on a regular paved surface where the tires are
intended to maintain ground contact.

 Category 2: This is a set of conditions for the operation of a bicycle that

includes Condition 1 as well as unpaved and gravel roads and trails
with moderate grades. In this set of conditions, contact with irregular
terrain and loss of tire contact with the ground may occur. Drops are
intended to be limited to 15 cm (6") or less.

If a bicycle/component is used in a higher category than defined, the stress on its
materials will increase. This results in a shortened life span of all components and, in
extreme cases, can lead to the failure of important components. This means an
increased danger of accidents and injury.

3.3 Explanation of the figures

All illustrations are outlines only and serve as examples. The details may vary from
your own E-Bike because the BMZ E-Bike system can be combined with a number of
different rechargeable battery variants. You can obtain detailed information about
the rechargeable battery used in your E-Bike from your cycle manufacturer and your
bicycle dealer.

23 Charging status

display

24 LED button

The five LEDs on the charging status display (23) show the charging status of the
rechargeable battery after pressing the LED button (24). Each LED equates to about
20% capacity. All five LEDs will light up when the rechargeable battery is fully
charged. The charging status of the activated rechargeable battery is also shown on
the display of the display unit (see 2.4.3). If the capacity of the rechargeable battery
lies below 10 %, the first LED on the charging status display flashes.

The rechargeable battery can be charged with and without the display unit. Without a
display unit, the charger can only be monitored on the charging status display. The
display unit can be removed during the charging process or can even be positioned
after the start of the charging process. The charging status is shown with the
charging status display on the rechargeable battery and via the bar on the display (4,
Figure 2, page 10). During the charging process, the LEDs of the charging status
display on the rechargeable battery shine. Each LED that shines permanently

 To switch off the rechargeable battery, press the LED button for > 3

seconds (see Figure 8, page 18).



The LEDs of the charging status display (23) go off.



The E-Bike system is also switched off at the same time.

3.6.2 Operating modes of the rechargeable battery

Once it is switched on, the rechargeable battery is in Active Mode. If no further action
is taken (operation or moving the E-Bike), it remains in Active Mode for two hours.

The Active Mode is activated by pressing the LED button (24), by charging the
rechargeable battery or placing the rechargeable battery into the E-Bike.

To minimise the system's internal consumption, the rechargeable battery
automatically switches to the Deep Sleep Mode after 2 hours in Active Mode, if there
is no activity and if the display unit is switched off. The Deep Sleep Mode is also
activated if the LED button (24) or the On/off button of the display unit is pressed for
at least three seconds or if the rechargeable battery is not in the E-Bike for more
than 30 seconds.

3.7 Maintenance, cleaning and storage

Keep the rechargeable battery clean. Clean it carefully with a dry and soft cloth. The
rechargeable battery may not be dipped into water or cleaned with a water jet. If the
rechargeable battery no longer functions, please contact an authorised dealer. Only
place the rechargeable battery on a clean surface. In particular, avoid soiling on the
charging connections and the contacts. Clean dirty or corroded contacts with a mild
cleaning agent or penetrating oil and protect them with battery terminal grease.

 Air humidity: 0-80 %
 Charging status: approx. 50 %

As the rechargeable battery gets older, its capacity will decrease, even if it is well
kept. If the operating time is much shorter after charging, this indicates that the
rechargeable battery is spent. It should be replaced.

After about three months in storage, check the charging status of the rechargeable
battery and charge it up to about 50 % if necessary.

3.8 Transport

The rechargeable battery may only be sent in hazardous good packaging bearing the
relevant warning information.

Please contact an authorised dealer, if you have any questions about transportation.
