Owner´s manual
2.1 Your A2B belongs to European Vehicle Category L1e (light two-wheel powered vehicle up to 45 km/h).
These electric bicycles with assistance up to 45 km/h are also generally called fast pedelecs (S-Pedelec or Speed Pedelec).
The A2B has an operating permit with Type Approval Number e13*2002/24*0639. The applicable existing statutory regulations and legal
provisions are explained in the following.
Registration number requirement
The A2B as homologated vehicle must be provided with a valid
insurance tag (vehicle insurance) which can be procured from
any insurance. This tag must be clearly legible when affixed to its
designated registration plate bracket.
Driving licence
L1e category light two-wheel powered vehicles may only be driven
if in possession of at least a Category M (as of 16 years of age)
driving licence.
Where you may ride
Riding on bicycle lanes and in pedestrian areas is not permitted for
light two-wheel powered vehicles, applicable within and outside
city limits. Riding on bicycle streets is only permitted if these
streets are generally approved for motor vehicles or motorcycles.
This also applies if you ride only by pedalling, meaning without
motor assistance.
Helmet requirement
At the time this owner's manual was written a standard Euro-
pean helmet requirement does not yet exist. Therefore, after you
have purchased your A2B, please consult your A2B specialist
dealer to find out the current legal situation in your country.
We therefore recommend you wear an appropriate helmet
for every ride.
Trailers
According to law, light two-wheel powered vehicles may only
pull cargo trailers.
It is prohibited to attach children's trailers to an S-Pedelec
(your A2B in this case) to transport children.

5
Replacing and modifying components
Specific components may only be used if approved for use with an
S-Pedelec in the type approval documents. When changing compo-
nents you should accordingly only use original parts or attachments
which have received legal approval for your A2B (or S-Pedelec).
This regulation concerns the following components:
• Lights (front & rear) & reflectors
• Brake system, side stand
• Electrical system (motor, battery, controller & display)
• Wheel rims and tyres
• Frame
• Registration number bracket
• Stem and handlebar
Unfit state to drive
Avoid using your A2B if you feel unwell and not completely fit.
Do not ride your A2B while under the influence of medication or
drugs. An alcohol level as of 0.5 will lead to fines and possible legal
consequences (suspension or revocation of your driving licence).
The rules and principles described here refer to the use of your
A2B in the European Union. For use outside the EU you should
obtain information beforehand about possible deviations.
Since legislature has not yet created uniform European stand-
ards and directives for S-Pedelecs, we would ask you to check
if the previously stated information is still current at the time you
purchase your A2B.
You will receive further information from your A2B specialist dealer
and at www.weareA2B.com.

Owner´s manual
3.2 Changing components or attaching accessories
Before you install any components or accessories (including other
tyres), ask your Hero Eco specialist dealer whether these are
suitable for your A2B.
Read and comply with the instructions of the respective
components or accessories which you have purchased for your
A2B. Follow the manufacturer's instructions for the components or
accessories if they differ from these instructions.
Just as for all mechanical components, your A2B is also
subject to a certain degree of wear. Especially in cases of high
loads, attention must be paid to wear characteristics. When
the useful life of a component is exceeded it can cause the
unexpected functional loss of this component, resulting in
serious injuries or even death. Therefore, pay attention to wear
characteristics such as cracks, scratches and changes in colour
at highly stressed points on the frame, fork, running wheels and
handlebars which would indicate that the useful life has been
reached or exceeded. Have your specialist dealer immediately
replace worn components.
If any components or accessories are not checked for
suitability and if they are not installed, used and maintained
properly, then this may result in serious injuries or even death. The
use of non original components or spare parts can jeopardise the
safety of your A2B, causing the warranty to expire.
A2B maintenance schedule
Your A2B should be professionally maintained by an A2B specialist
dealer at regular intervals. Read the information in chapter 13.0
(pg.39) to that effect.
The replacement of components or installation of accessories
occurs at your own risk, since these parts have not been checked by
Hero Eco for suitability, reliability or safety with your A2B.
3.3 Brake lever adjustment
Can you comfortably operate the brake lever? If not, take your A2B
to your A2B specialist dealer and ask them to adjust the angle of the
brake levers.
Otherwise you can adjust the brake lever angle yourself:
1. Loosen the screw under the brake lever with an appropriate Allen
key.
2. Adjust the angle as required.
3. Re-tighten the screw and ensure that the brake lever is securely
fixed in position.
To adjust the brakes you should take your A2B to an A2B
specialist dealer.

3.4 Seat height adjustment
The seat may require adjustment. Ask your A2B specialist dealer
to do this before you ride. However, you can adjust the seat height
yourself as follows:
1. Stand over your assembled A2B, your feet placed flat on the
ground approximately shoulder width apart.
2. There should be a gap of at least 25 mm between the frame
height (1) and the inside leg length of the rider (2).
Adjusting the height
1. The seat height can be adjusted by releasing the seat post clamp
for the seat post.
2. Adjust the seat to the required height. DO NOT IN ANY CASE
adjust the seat higher than the minimum insertion marking on the
seat post.
3. Press the lever of the seat post clamp towards the frame until it is
locked. The lever may not stick out in order to avoid injuring yourself.
The lever is securely fastened when it requires a particular force to

press it in the closed position. A correctly closed seat post clamp
cannot be moved except by opening it once more according to the
method described above. If you can move the mechanism slightly,
open the lever of the seat post clamp, turn the adjusting nut by
another 180° and then try again.
4. After the height adjustment, check to see if the seat can be
moved in any other direction.
An improperly fastened seat can result in serious injuries or
even death. Make certain that the screw of the seat clamp (seat
post - seat) has been tightened with 27 Nm.
• This owner's manual does not make any guarantees as to the
safe use of the A2B under all conditions.

4.0 Getting to Know your A2B
If after reading this section you still have questions, ask your A2B specialist dealer to explain any functions or characteristics that
are unclear to you before your first ride.
4.1 An A2B overview
The A2B is equipped with a force sensor.
As soon as you begin to pedal you will
discover that the motor starts up and
assists you - making cycling an effortless
pleasure. In addition to this pedalling
assistance you'll find next to the left grip a
starting aid which accelerates the motor -
regardless of your pedalling power - up to
20 km/h.
4.2 Your first trip
1. Put your helmet on and choose a quiet
location away from cars, obstacles or other
hazards.
2. Make certain the battery is charged and
connected.
3. Activate the system with the electronic
key (see 4.3).
4. Do NOT sit down on the A2B while it is
still on its kickstand. You will damage the
kickstand and possibly the frame.
5. Mount your A2B and find a comfortable
sitting position.
6. Step on the pedals to start the motor
assistance.
7. Test the brakes at slow speed. The left
brake lever operates the front brake, the
right brake lever operates the rear brake.
Pulling the brake lever too tightly may block
the wheel, causing you to lose control of
the bicycle and fall down.
Please remember that a motor cut-out
is integrated in the right brake lever. The
electric power supply to the motor is cut
off the moment you activate the right brake
lever. Therefore, do not keep the right brake
lever operated when you want the motor to
run.
8. Try the handling and response of your
A2B. Familiarise yourself with how the
suspension responds when you operate the
brakes and when you shift your weight.

13
4.3 Display and electronic key
Switching the electronic system on and off at the display
Your A2B is secured by electronic key (also called E-key). You must
activate the system before you begin riding.
1. Hold the E-Key directly over the screen of your display.
2. The display now lights up. As soon as the A2B lettering appears,
pull the key away.
3. After the ride: to shut off the system hold your E-Key over the
display until it blanks out. Then pull the E-Key away. The system is
now deactivated.
The E-Key is used to wake the display, battery and motor control
from sleep mode. If not all of the components wake up after first
switching on with the E-Key (e.g. no motor assistance), deactivate
the system and repeat the switching on process with the E-Key.

Owner´s manual
4.10 Gears
Your A2B has a derail-
leur that is operated by the
right-side gear shifter at the
handlebar. To make pedal-
ling easier (e.g. at an incline),
press the lever (A) and shift
down a gear. You then need
to pedal more quickly in
order to maintain the same
speed.
If you wish to ride faster (on
even terrain or downhill), pull the lever (B) and shift up a gear. You
can now pedal more slowly but will have to expend more effort.
Never pedal backwards
when shifting gears. The
chain could jump off, making
you lose control which could
result in accidents with seri-
ous injuries or even death
and/or property damage.
Always pedal evenly after
shifting gears.
The derailleur operates inde-
pendently of the motor. Use
the derailleur to adjust the
gear setting to find a gear that
makes pedalling comfortable
whilst assisting the motor.
4.11 Lights
Set the switch at the rear side
of the head light to the cor-
responding direction to switch
the lights on or off.
