1.0 Introduction
Welcome and congratulations on buying your new A2B Shima*, the electric bike that’s taking transport in a whole new direction. It’s the
revolutionary way to get to work, visit the shops or just get some fresh air. Compared to jumping in the car, an ebike is a lot more fun,
easier to park and will reduce your fuel costs as well as your impact on the environment… as you’ll soon find out!
Feeling energetic?
You can ride your new A2B Shima powered off and then switch the assistance on for hills and headwinds. We dedicated our new bikes
to pioneers that redefined the way we do things in the modern World. As a tribute, the A2B Shima bike was named after Hideo Shima,
a japanese railway engineer and the driving force behind the development and building of the first bullet train (Shinkansen).

Owner’s manual
2.1 Your A2B belongs to European Vehicle Category L1e capability (light two-wheel powered vehicle up to 45 km/h (28 mph).
Ebikes with up to 45 km/h (28 mph) are also 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 below.
Registration number requirement
The A2B as a homologated vehicle must be provided with a valid
insurance tag (vehicle insurance). This can be obtained from
any insurance company and must be clearly displayed on the
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 in 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, without motor assistance.
Helmet requirement
At the time this owner's manual was written a standard European
helmet requirement does not yet exist. Therefore, after you have
purchased your A2B, please consult with your A2B specialist
dealer to find out the current legal situation in your country.
However, we recommend you wear an appropriate helmet for
every ride.
Trailers
Please check relevant legislation for your area for a full
understanding of all necessary legal requirements. According to US
law, light two-wheel powered vehicles may only pull cargo trailers.
It is prohibited to attach childrens trailers to a S-Pedelec
(yourA2B in this case) to transport children.
*Not applicable in all markets, please check local legislation.

7
Replacing and modifying components
Specific components may only be used if approved for use with a
S-Pedelec in the approval documents. When changing components
you should only use original parts or attachments which are legally
approved for your A2B (or S-Pedelec).
This regulation applies to the following components:
• Lights (front and rear) and reflectors
• Brake system
• Side stand
• Electrical system (motor, battery, controller and 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,
drugs or alcohol. Local law enforcement may issue a fine or criminal
conviction for riding under the influence of medication, drugs or
alcohol.
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.
As European standards and directives for S-Pedelecs have not
been unified yet, we would ask you to check if the previously stated
information is still current at the time you purchased your A2B.

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, 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,
and can invalidate your warranty.
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.42) to that effect.
The replacement of components or installation of accessories is
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.

11
3.4 Adjustment of the seat height
The seat height may have to be adjusted. Please ask your A2B
specialist dealer to adjust the seat height before your first tour. You
may also adjust the seat height on your own as indicated below:
Determination of the correct driver's seat height
There are several ways of determining the correct seat height; the
method which can be carried out without any further auxiliary means
is described in the following: Sit on the saddle and stretch one leg.
Put your foot's heel on the pedal which is on the lowest point of the
crank turn. Your knee should now be almost straightened.
If you are sitting straight on the saddle while having this position,
the saddle's height is correct.
Of course, you then do not drive with legs stretched. If you put your
foot on the pedal while having the correct driving position (ball of
foot and metatarsophalangeal joint above the pedal axle), the knee
will remain slightly angled also on the lowest point of crank turn if
the saddle height has been adjusted correctly.
A short test ride is recommended to find out if the saddle is too high.
If the pelvis tilts to the right and the left in the rhythm of pedalling, the
saddle is too high. If the saddle is too low, you will usually find it out
only after many kilometres through pain in the knees.

12
Owner’s 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 BY NO MEANS.
3. Push the lever of the quick release towards the frame, until it will
be closed again. The lever must not stick out to avoid danger
of injuries. The lever is safely attached if you must use efforts
to push it into the closed position. The efforts are appropriate if
the lever leaves a mark on the palm of your hand when pressing.
A properly closed quick-release cannot be moved anymore
unless it is reopened as specified above. If you can move the
mechanism slightly, open the lever of the quick release, turn the
adjusting nut by another 180° and try again.
4. After height adjustment, check if 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 18.5 Nm.
• This user manual does not express any guarantee 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 Overview
The A2B is equipped with a torque 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 pedal assistance you will
find a starting aid next to the left grip. This
starting aid will accelerate the motor up
to 20 km/h (12.5 mph), regardless of your
pedaling power.*
*Not available in all markets
4.2 Your first trip
1. Wear your helmet and choose a quiet
location away from cars, obstacles or
other hazards.
2. Ensure that the battery is charged and
connected.
3. Activate the system with the electronic
key (see section 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.
8. Pulling the brake lever too tightly may
lock the wheel, causing you to lose
control of the ebike.
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.
9. 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.

4.3 Display and electronic key
Switching the electronic system on and off at the display
Your A2B is secured by an 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,
move the E-key away.
3. After the ride: to turn off the system hold your E-Key over the
display until it blanks out. The system is now deactivated.
The E-Key is used to wake up the display, battery and motor
controller from sleep mode. If all of the components do not wake
up (e.g. no motor assistance), deactivate the system and repeat the
process.
