Before installing any component or accessory,
including a different tyre, make sure that it is com-
patible with your A2B by checking with your A2B
dealer.
Read, understand and follow the instructions that
accompany the component or accessory you
purchase for your A2B . Follow the component
manufacturer’sinstructions if they conict with
these instructions.
As with all mechanical components, the bi-
cycle is subjected to wear and high stresses.
Different materials and components may react
in different ways to wear or stress fatigue. If the
design life of a component has been exceeded, it
may suddenly fail possibly causing serious or fatal
injuries to the rider. Any form of crack, scratches
or change of colouring in highly stressed areas,
such as frame, fork and handle bar, indicates that
the life of the component has been reached and it
should be replaced immediately by an A2B dea-
ler.
Failure to conrm with compatibility, proper
installation, operation and maintenance compo-
nents or accessories can result in serious or fatal
injury.
Using non-genuine components or replace-
ment parts may compromise the safety of your
A2B and void the warranty.
If you change components or add accesso-
ries, you do so at your own risk because Hero
Eco may not have tested that component or ac-
cessory for compatibility, reliability or safety on
your A2B .
3.3 Brake lever adjustment
Can you comfortably operate the brakes? If not,
take your A2B to an A2B dealer and ask them to
adjust the angle of the brake levers.
Alternatively, follow the instructions below to ad-
just the brake lever angle:
1. Loosen the bolt underneath the brake lever
with an appropriate allen key.
2. Adjust the angle to suit.
3. Tighten up the bolt underneath, ensuring the
brake lever is rmly xed in place.
Should you need to adjust the brakes them-
selves, please take your A2B to an A2B dealer to
make the required adjustments.

3.8 Seat height adjustment
The seat height may require adjustment. Ask your
A2B dealer to adjust it before you ride, however
to adjust the seat yourself follow these instruc-
tions:
To determine the correct height of the seat
for the rider
1. Straddle the assembled A2B with your feet
shoulder-width apart and at on the ground.
2. There must be at least 25 mm/1 inch clearance
between the frame height (1) and the inside leg
measurement of the rider (2).
Height adjustment
1. Release the seat post quick release by rota-
ting the quick release lever away from the seat
post until it is fully open.
2. Adjust the saddle height accordingly to your
request. DO NOT raise the seat beyond the ‘mini-
mum insertion’ mark on the seat post.
3. Firmly grip the seat tube with your hand, and
push the lever over to the closed position towards
the frame, ensuring that it does not protrude so
as to cause injury to the rider. The lever is secu-
rely tightened when it takes a signicant amount
of force to position it in the closed position. The
appropriate amount of force necessary to close
the lever when it is properly adjusted will result in
an imprint of the lever in the palm of your hand.
When properly closed, it is impossible to move
unless you open it again by reversing the steps
above. If you can easily move it, open the quick
release lever and tighten the adjusting nut another
180º and try again.
4. After adjustment, ensure there is no move-
ment in the seat position in any direction.
Failure to correctly secure the seat can result
in serious or fatal injury.
Ensure the seat clamp bolt (seat pillar - seat post)
is tightened to 27 Nm.

4.0 Understanding your A2B
4.1 A2B Overview
Having read this section, if you are still unsu-
re, please ask an A2B dealer to explain any
functions or features that you do not under-
stand before your rst ride.
The A2B has a ’true pedal assist’ function, this
means the motor engages only when the rider is
pedalling. So you can get places under your own
steam yet have the comfort of the electric motor
giving you that extra boost along the way.
4.2 Starting and stopping
1. Select a quiet area away from cars, other cyc-
lists, obstacles or other hazards.
2. Make sure that the battery is fully recharged.
3. Power ON the electronic system by turning
the battery power on.
4. Raise the kickstand into the riding position.
DO NOT sit on the A2B while it is supported by
the kickstand, you will damage the kickstand
and, possibly the frame.
5. Mount your A2B and get comfortable.
6. Apply motor power by pedalling the A2B .
7. Test the brakes at slow speed. The right
brake lever actuates the rear brake and the
left brake lever actuates the front brake. Ap-
plying brakes too hard can lock up a wheel,
which could cause you to lose control and fall.
8. Check out the handling and response of your
A2B . Familiarise yourself with how the suspen-
sion responds to application of the brakes and
shifts in rider weight.
Remember that there are power cut-off swit-
ches embedded into the brake levers. When
you apply the brakes, power to the motor will
turn OFF. Therefore, do not hold the brake levers
when you want the motor to run.
12page
You can choose between 3 power assistance le-
vels for your A2B . To enter the programme me-
nue turn the knob untill (P) appears.
Now press the knob to switch between the mo-
des. The mode icon will ash and your assistance
level will be set automatically .
• P0 - off (no assistance).
• P1 - economic (minimum motor assistance,
ideal for saving battery power, maximum range).
• P2 - standard (normal motor assistance, ave-
rage range).
• P3 - high power (maximum motor assistance,
reduced range).

4.5 Gears
Your A2B has a rear derailleur controlled by the
gear shifter on the right side of the handlebar.
To shift gears, pedal at a steady pace and push
the shift lever A or B until you nd the gear most
comfortable for you and the current conditions.
To make pedalling easier (when encountering a
hill), push up lever A in riding direction to down-
shift, this will also make you pedal faster to achie-
ve any given speed. Push up lever A against stop
to down-shift two gears at once.
To ride faster (on a at section or a downhill), push
up lever B to up-shift, allowing you to pedal more
slowly for a given speed, but with more effort re-
quired.
Never pedal backward while shifting gears.
The chain could derail and you could lose control,
resulting in an accident that could cause serious
or fatal injury and/or property damage. Always
pedal forward at a steady pace when shifting ge-
ars.
The rear derailleur operates independently of the
motor. Using the derailleur control, adjust the
gear setting to nd a gear that makes pedalling
comfortable while assisting the motor.
4.6 Light
To switch the light on and off push the switch on
the headlight to on or off position.
You can ride your A2B without attaching the
battery. The motor will generate power for the
lights.

4.7 Luggage Carrier
Your A2B equipped with a durable luggage car-
rier. In case you need to carry luggage or any
goods with your A2B , please carefully read the
enclosed instructions before using the luggage
carrier.
1. The rack is attached to the carrier support by
4 x countersunk screws. The support is screwed
on the frame by 4 x countersunk screws. If you
are frequently using the luggage carrier, always
check that the screws are secured tightly at
torque value 6-8 Nm.
2. The maximum weight that could be carried is
10 Kg.
3. Please ensure that the luggage is fastened se-
curely, so that it can not fall off while riding. Take
care that loose straps or other itms can not get
caught by the spokes or wheels while riding.
4. The luggage carrier is not designed for carry-
ing a second rider or for the attachment of a child
seat. It should also not be used to pull a trailer.
5. Do not modify the luggage carrier.
6. Distribute the weight of your luggage or goods
evenly between the two sides of the luggage car-
rier.
7. Please be aware when the luggage carrier is
loaded, your A2B may behave differently, espe-
cially when steering or braking.

owner´s manual
4.8 At the end of your ride
If you have any questions, or if you feel anything
about your A2B is not as it should be, ask your
A2B dealer before you ride again.
Recharge your discharged battery
Fully recharge your battery within 3 days if the
battery is completely discharged because a lithi-
um ion battery left in a discharged condition dete-
riorates much faster than a fully charged battery.
See 5.3 & 5.4.
Your range
Factors affecting range:
• Pedal assist mode
• Battery state-of-charge
• Use of gears appropriate to speed
• Tyre ination pressure
• Front wheel bearings and both brakes (tight
bearings or a dragging brake shoe reduces range)
• Rider weight (it takes more energy to accelera-
te a heavier person)
• Your speed and wind conditions (range is re-
duced when pedalling hard against a high wind)
• Terrain (travelling on a soft surface or climbing
a hill uses more power)
• Frequent starts and stops (full power from a
standing start draws the most amperage from
the battery)
Maximise your range
• Fully charge your battery before each ride
• Check tyre pressure regularly and inate to the
pressure of 4.5 bar for front tyre and rear tyre
• Have your A2B serviced at least once a year
to ensure that the wheel bearings turn freely and
the rims do not bind the brake shoes when the
brakes are not applied
• Minimise the weight that you carry
• Ride at slower speeds
• Use the economy mode as much as possible and
support the motor by pedalling with your own power
• Keep the chain and derailleur lubricated with
bicycle recommended chain spray
