1.0 Introduction
Congratulations on your purchase of the new A2B Ørsted*, the
e-bike that will significantly change your mobility. A2B has set itself
the goal of redefining your daily mobility together with you and
getting you from A to B in style. Driving an A2B is more fun than
driving a car, avoids the frustrating process of looking for parking
spaces, saves on fuel costs and, at the same time, protects the
environment. You can redefine your paths with the A2B. Whether
you ride your A2B to work, for shopping or just for fun, you will
rediscover your world. In order to take the idea of travelling familiar
paths differently, doing everyday activities in differently from before
and changing our behaviour into account, we named our A2B
models after various individuals. These individuals have strongly
influenced and changed our everyday life thanks to their ideas,
inventions and developments. In the case of the A2B Ørsted,
the name chosen for the bike is an hommage to Hanna Christian
Ørsted, a Danish physicist and chemist whose research and
discoveries in the field of electrical engineering first made the use
of electricity possible.
1.1. Intended use of your A2B
Your A2B, equipped with the neodrives drive system, is a Pedelec
(Pedal Electric Cycle) for usual transport of one person on public
roads. Any adjustments and repairs to the A2B and its components
shall only be regarded as intended use insofar as they are stated
in and permitted by these operating instructions, the component
manufacturer's instructions or further documents provided upon
purchase of the Pedelec. The manufacturer does not assume any
liability for damage caused negligently due to misuse, improper
use or improper or omitted maintenance or repairs. The driver is
responsible for examining the Pedelec as required, having any
necessary works carried out and using it appropriately.
These operating instructions describe the use of your A2B and its
components and correspond to the latest version of this technology
at the time of printing. The manufacturer reserves the right to make
changes resulting from the further development of mechanics, the
software or from the statutory requirements.

User manual
3.2 Replacement of components, fitting of accessories
Before mounting any components or accessories (including
different tyres), you should ask your certified A2B specialist dealer
if they are appropriate for your A2B.
Please read and observe the instructions for the respective
components or accessories you have bought for your A2B. Please
observe the manufacturer's instructions for the components or
accessories if they are different from these instructions.
Like all mechanical components, your A2B is subject to wear
and tear. The user must particularly watch out for wear and tear
under higher workloads. If a component's life cycle is exceeded,
this component may suddenly become inoperative leading to severe
or even fatal injuries. Please therefore watch out for signs of wear
and tear such as cracks, scratches and changes of colour in areas
which are subject to high strain, e.g. on the frame, fork, wheels and
handlebars, indicating that the life cycle has been completed or
even exceeded. Have worn components replaced immediately by
your specialist dealer.
If you do not check components or accessories for fitness
and install, use and maintain them properly, this can lead to severe
or even fatal injuries.
The use of non-original components or spare parts may
endanger your A2B's safety and void the warranty.
The replacement of components or fitting of accessories will
be made at your own risk, since the fitness, reliability or safety of
these parts for use with your A2B may not have been checked by
Hero Eco.
3.3 Adjusting the brake levers
Are you able to easily operate the brake levers? If not, take your
A2B to an A2B specialist dealer to have the angle of the brake
levers adjusted.
Alternatively, you can adjust the brake levers' angle yourself as
indicated below:
1. Loosen the screw below the brake lever using an appropriate
Allen key.
2. Adjust the angle as required.
3. Tighten the screw and make sure the brake lever is held securely
in place.
For adjustment of the brakes, you should take your A2B to an
A2B specialist dealer.

3.4 Adjusting the seat height
The seat height may need to be adjusted. Please ask your A2B
specialist dealer to adjust the seat height before your first journey.
You can also adjust the seat height yourself as indicated below:
Determining the correct seat height for the rider
There are several ways of determining the correct seat height; the
method which can be carried out without any other equipment is
performed as follows: Sit on the saddle and stretch one leg. Put
the heel of your foot on the pedal which is at the lowest point of the
crank turn. Your knee should now be almost straight.
If you are sitting right on the saddle while in this position then the
saddle height is correct.
Of course, you do not then ride with your legs stretched. When you
put your foot on the pedal while in the correct riding position (ball
of the foot and base of the toe joint above the pedal axle), the knee
will still remain slightly bent at the lowest point of the crank turn if
the saddle height has been adjusted correctly.
A short test ride will tell you if the saddle is too high. If your pelvis
tilts to the right and left in time with the pedalling rhythm then the
saddle is too high. If the saddle is too low, you will usually only find
out after many kilometres with pain in your knees.

User manual
Height adjustment
1. The seat height can be adjusted by loosening the quick release
for the saddle post.
2. Position the saddle at the desired height. Do NOT position the
saddle higher than the minimum insertion mark located on the
saddle post UNDER ANY CIRCUMSTANCES.
3. Push the quick release lever towards the frame, until it is closed
again. In order to avoid the risk of injury, the lever must not stick
out. The lever is safely fastened if it takes effort to push it into
the closed position. The amount of effort is appropriate if the
lever leaves a mark on the palm of your hand when pressing.
A properly closed quick-release cannot be moved any more
unless it is reopened as specified above. If you can move
the mechanism slightly, open the quick release lever, turn the
adjusting nut by another 180° and try again.

4. After height adjustment, check that the saddle cannot be moved
in any direction.
An improperly attached saddle may lead to severe or even
fatal injuries. Ensure that the saddle clamp screw (saddle post -
saddle) has been tightened using 27 Nm.

User manual
4.0 Familiarising yourself with the functions of your A2B before your
first journey
If you still have any questions after having read this section, please ask your A2B specialist dealer to explain any unclear
functions or features to you before your first journey.
4.1 A2B at a glance
As soon as you start to pedal when the drive system is enabled, you
will notice that the motor will start and assist you based on the level
of assistance selected - making riding a bike an effortless pleasure.
4.2 Starting and stopping
1. Put your helmet on and look for a calm place without any
obstacles, cars or other hazards, if possible.
2. Ensure that the battery has been charged and connected
correctly
3. Activate the drive system by pressing the controller's middle
button next to the left handlebar grip.
4. Fold the stand up into the riding position.
Do NOT sit on the A2B if it is still
supported by the stand. By doing so, you
damage the stand and possibly the frame.
5. Sit on the A2B and find a comfortable
sitting position.
6. Start to pedal and start the motor
assistance in this way.
7. Test the brakes at low speed. The left brake lever activates the
front wheel brake, the right brake lever activates the rear wheel
brake. If you pull the brake levers too hard, a wheel may become
locked which could cause you to lose control of the bicycle and
fall. Remember that both brake levers include a motor switch-off
device; as soon as you operate one of the two brake levers, the
motor's power supply will be switched off, so do not brake if the
engine should remain running.
Remember that both brake levers include a motor switch-off
device. As soon as you operate one of the two brake levers, the
motor's power supply will be switched off, so do not keep a brake
lever pulled if the motor should remain running.
8. Test the handling and reactions of your A2B. Familiarise yourself
with how the suspension responds to the brakes being operated
by the rider and the shifting of the rider's weight.

13
in a forward direction when
shifting into another gear.
The derailleur operates
independently from the motor.
Using the derailleur, select a
gear which allows you to pedal
comfortably and, at the same
time, helps the motor.
4.4 Lights
Turn the on/off switch located on the headlamp to the applicable
position to switch the lights on or off.
4.3 Gear box
Your A2B is equipped with a
derailleur activated by the two
pressure levers at the right-
hand side of the handlebar.
To facilitate pedalling (e.g. at
gradients), you operate the
large lever located in front of
the handlebar and marked with
A in the illustration. In this way,
you shift down and have to
pedal faster to maintain your
speed. If you want to go faster
(on the flat or downhill), you
shift up one gear using the
smaller lever which is marked
as B in the opposite figure and
located behind the handlebar
from the driver's point of view.
You can pedal slower, but you
have to use more effort.
Do not ever move the pedals backwards when shifting into
another gear. The chain could come off and you may lose control
of the bicycle which could lead to accidents resulting in severe or
even fatal injuries and/or material damage. Always pedal evenly and

4.5 Luggage rack
Your bicycle model is not equipped with a luggage rack as
standard, however your A2B's battery has a slot for a Rack-Time
luggage rack adaptor. This adaptor can be ordered through
your A2B specialist dealer using the order no. 625450098300
and installed on the bicycle. This adaptor enables you to install
various luggage transport options from Rack-Time. You can from
choose either luggage baskets or a range of saddle bag solutions.
Alternatively, you can just use the base plate and a standard
Racktime luggage rack. Please ask your A2B specialist dealer for
information about the various options and the best solution for your
needs. No matter which solution you choose, please be aware of
the following when transporting your luggage:
1. Your A2B's battery is equipped with an integrated LED rear
light. When riding at dusk or in the dark, please ensure that your
luggage is fixed in such a way that the rear light is not covered,
either completely or in part, since this results in a high risk of not
being noticed by other road users.
2. Make sure the luggage is safely attached to the luggage rack
and cannot fall off while riding. Ensure that loose tightening
straps or other objects cannot get into the spokes while riding.
3. Observe the maximum permitted load of 25 kg in addition to
the bicycle's standard fittings on the rear of the bike. Do not
overload the luggage rack.
4. This vehicle is not designed or approved for transporting a
second passenger, transporting a child in a fitted child seat or
for pulling a trailer.
5. The total permitted weight for your A2B must not be exceeded.
The maximum total permitted weight is indicated in the
specifications.
6. Distribute the weight of your luggage or the objects to be
transported evenly on both sides of the luggage rack.
7. Please remember that luggage or other loads present on the
luggage rack alter the handling of your A2B. This applies in
particular to steering and braking responses.
Failure to observe these directions may lead to severe or
even fatal injuries and/or material damage.

15
At the end of your first journey
If you have any questions or feel that your A2B has not yet
been adjusted and adapted to you as well as possible then we
recommend that you contact your A2B specialist dealer before
using your A2B again.
Your range
Factors affecting the range:
• Support level
• Battery charge level
• Use of the correct gears for your speed
• Tyre pressure
• Front wheel bearing and both brakes (tight bearings or rubbing
brake blocks will reduce the range)
• Driver's weight (more energy is required to accelerate a heavy
person)
• Your speed and the wind conditions (quick pedalling into a strong
headwind reduces the range)
• Terrain (riding on soft areas or uphill requires more efforts)
• Frequent starting and stopping (full power from a standstill uses
the most battery power)
Maximising your range
• Completely charge the battery before every journey.
• Check the tyre pressure regularly and inflate the tyres to a
pressure of 3.5 bar (front and rear tyres).
• Have your A2B serviced regularly to ensure that the wheel
bearings are rotating freely and the brake blocks do not rub on
the brake disks.
• Keep the total weight as low as possible.
• Ride at low speeds.
• Use the energy saving mode as often as possible and assist the
motor by pedalling on your own.
• Lubricate the chain and derailleur using a special chain spray for
bicycles.
