3. components on the bike and adjustment features
3.1 Replacement of components, mounting of accessories
Before installing any components or accessories (including other tyres), check with your dealer to see if they are
suitable for your A2B. Read and follow the instructions for each component or accessory you have purchased
for your A2B. Follow the manufacturer's instructions for the components or accessories if they differ from these
instructions.
As with all mechanical components, your A2B is subject to a certain amount of wear and tear. Particularly at
higher loads, wear characteristics must be taken into account. If a component's service life is exceeded, this can
lead to an unexpected loss of function of the component, which can result in serious or even fatal injury.
For this reason, pay attention to wear and tear such as cracks, scratches and colour changes in highly stressed
areas on the frame, fork, wheels and handlebars, which indicate that the service life has been reached or
exceeded. Have worn components replaced immediately by your dealer.
Failure to test, install, use and maintain any components or accessories properly may result in serious or even
fatal injury.
Use of non-original components or spare parts may endanger the driving safety of your A2B and void the
warranty. Replacement of components or the attachment of accessories is at your own risk, as these parts may
possibly cause damage to the equipment. have not been tested by Hero Eco for suitability, reliability or safety
with your A2B.
3.2 Adjusting the brake levers
Can you operate the brake levers comfortably? If this is not the case, take your A2B to a dealer and ask them to
adjust the angle of the brake levers. Otherwise, you can adjust the angle of the brake levers yourself as follows:
Loosen the screw under the brake lever with a suitable Allen key.
Adjust the angle as required.
Tighten the screw again and make sure that the brake lever is securely fixed in position.
Before a short test drive, check that the brake levers are firmly seated and that they cannot be twisted. To
adjust the brakes yourself, you should take your A2B to a dealer.

3.4 Seat height adjustment - theory
The seat height must be adjusted correctly. Ask your dealer to do so before your first trip. Alternatively, you can
also adjust the seat height yourself as follows.
Determination of the correct seat height for the driver
There are several ways to determine the correct seat height, the following is a description of the method to be
used without any additional aids: Sit down in the saddle and stretch one leg. Place the foot with the heel on the
pedal, which is at the lowest point of the crank revolution. The knee should now be almost pushed through. If
you are sitting on the saddle in this position, it has the right height.
Of course, do not drive with your legs stretched. If you put your foot on the pedal in the correct driving position
(footballs with a toe base joint above the pedal axle), the knee remains slightly angled even at the lowest point
of the crank revolution with the saddle height set correctly. A short practice session is enough to find out if the
saddle is too high. If the pelvis tilts to the left and right at the rhythm of pedaling, the saddle is too high. If the
saddle is too low, you will notice this only after many kilometres, mostly due to knee pain.
How to adjust the seat height - Practice:
The seat height can be adjusted by loosening the quick-release or the Allen screw for the seat post.
Set the saddle to the desired height. DO NOT place the saddle ON ANY OCCASION higher than the minimum
insertion mark on the seat post.
mapping
Push the lever of the quick release lever towards the frame until it is closed again. The lever must not protrude
to prevent you from getting injured. The lever is securely secured when it requires a certain amount of force to
push it into the closed position. You can see the appropriate amount of force by the fact that the lever leaves an
impression on your palm when you squeeze it. A properly closed quick-release can no longer be moved, except
by re-opening it using the procedure described above. If you can move the mechanism easily, open the lever of
the quick-release, turn the locknut another 180º and try again. If the seat post should be clamped with a
hexagon socket screw (INBUS), tighten the screw with the specified tightening torque.
After adjusting the saddle height, check that the saddle cannot be turned in any direction.
A saddle that is not properly secured can cause serious or even fatal injuries. Make sure that the saddle fixation
bolt (saddle support - saddle) is tightened to the specified torque.
Carrier:
Your vehicle may have a luggage carrier.
The maximum load capacity is 10 kg, unless the carrier indicates a higher load capacity.
Make sure that the luggage is securely secured on the rack and cannot fall off while driving. Make sure that
loose straps or other objects cannot get caught in the spokes while driving.
Do not load the carrier.
The vehicle is not designed or approved for the transport of a second person or a child without a child seat.
The permissible total weight of your A2B must not be exceeded. The maximum permissible total weight is
specified in the specification.
Distribute the weight of the luggage or items to be transported evenly on both sides of the rack.
Note that luggage or other loads on the rack will change the driving behaviour of your A2B. This applies in
particular to the steering and braking characteristics.
Failure to observe these instructions may result in serious or even fatal injury and/or damage to property.
At the end of your first journey
If you have any questions or have the impression that your A2B is not yet optimally adjusted and tuned to you,
we recommend that you consult your dealer before continuing to use your A2B.

3.4 Your range
Factors affecting range:
support level
battery charge level
Use of the correct gears for the respective
applications
pace
tire pressure
Wheel bearings and both brakes (narrow bearings
or abrasive pads reduce the range)
Total weight (accelerating a heavier person or
high payload requires more energy)
Their speed and wind conditions (fast kicking in
strong headwinds reduces the range)
Terrain (driving on soft surfaces or uphill requires
more power)
Frequent starts and stops (full power from
standstill requires the most power from the
battery) To maximize your range:
Fully charge the battery before every ride.
Check the tyre pressure regularly and inflate the
tyres to a pressure as indicated on the tyre.
Have your A2B serviced regularly to ensure that
the wheel bearings rotate freely and that the
brake pads do not rub against the brake discs.
Keep the total weight as low as possible.
Drive at lower speeds.
Use the power save mode as often as possible
and support the motor by pedaling on your own.
Lubricate the chain and derailleur with a chain
spray recommended for bicycles.

5.1.5.1 Rear engine - removal and installation
The drive wheel of your pedelec can be removed from the bicycle frame at any time, for example for cleaning
purposes or in case of a puncture. Proceed with utmost care in this respect and during the subsequent
assembly, paying particular attention to the instructions and information provided by the manufacturers of the
various components attached to the wheel, in particular the brake disc.
5.1.5.2 Removing the drive wheel
Before removing the drive wheel, make a note of the cable laying and the fixing points of the cable ties. First of
all, loosen and remove all cable ties that are used to attach the cable coming from the motor, as well as cables
and leads of other components to the bicycle frame. Then disconnect the plug on the motor cable from the
socket on the battery cable. Loosen the two nuts or quick-release with which the wheel is attached to the

10
frame, so that the complete wheel can be removed from the frame of your pedelec. If necessary, you may have
to disengage the brake. Never hold or transport the removed wheel on the cable coming from the motor! There
is a risk of cable breakage.
5.1.5.3 Attaching the drive wheel
Make sure that all components attached to the wheel are installed in accordance with the manufacturer's
instructions and specifications. This applies in particular to the brakes and gear shifting. Do not forget to
reassemble the torque arm/discs in the same position in which they were removed before. Then slide the wheel
into the frame's seat and tighten it with the axle nut in the following order:
First tighten on the side of the gear shift then apply the brake on the side of the brake
The tightening torque of the two nuts is between 30 and 40 Nm. Make sure that the washer is located under
the axle nut, otherwise there is a risk of loosening the axle nut.
If your wheels are equipped with quick-release clamps, please observe the manufacturer's instructions for
assembly and tightening torque.
If the wheel is correctly attached to the frame, the motor can be connected to the end of the cable leading to
the battery. Make sure that the plug is correctly aligned with the socket. Attach all cables and supply lines to the
bicycle frame with cable ties and carry out a final function test. Make sure that the cables are correctly routed,
as the cable could get caught in the brake disc, drive unit or spokes if they are incorrectly routed, which could
cause the wheel to lock and fall.
6. cleaning, care and maintenance
6.1 Maintenance
Have your A2B checked by a dealer at least once a year. Please refer to the section Maintenance schedule.
6.1.1.1 Wheels
The front and rear wheels should be centered in the fork and frame. Check the wheels regularly for correct
spoke tension and rim alignment. DO NOT use your A2B with damaged or missing spokes. The wheels should
run evenly and without fluttering vertically or vertically.
6.1.2 Hub bearings
Check the seat of the hub bearings regularly by lifting and rotating the wheel from the ground and by trying to
move the rim sideways between the fork or frame. There should be no lateral movement. If you notice a
movement in the lateral direction of a wheel, the hub bearings must be adjusted or replaced.
6.1.3 Rims
The rims should not show any cracks, dents or flat spots. If necessary, take your A2B to a dealer for repair
and/or adjustment of the wheels.
6.1.4 Drive chain
Your A2B has a high-quality chain. This must be cleaned regularly and lubricated with a synthetic lubricant
specially recommended for bicycles.
6.1.1 Brakes
Check the brake cables for signs of wear and abrasion. Tighten the brake lever firmly and check that the brakes
function properly. Make sure that the rotors are free of residues and oil. Never wait until the brake linings are
completely worn. Replace the brake pads if necessary. If your brake pads look worn out or the brakes do not
respond as well as usual, ask a specialist dealer to check and replace them. Brakes are less effective in wet
conditions.

11
Driving in wet conditions: You should always remember that your A2B has a longer braking distance. Slow
down, keep a longer distance between yourself and other road users and slow down sooner than usual.
Failure to observe these safety precautions could result in accidents with serious or even fatal injuries and/or
damage to property. If you have any questions about using the brakes, please contact your dealer. Brake discs
and brake linings must be free of oil and grease.
6.1.2 Tyres
Check the tyres for damage, cracks and unusual or severe wear and tear. The tyre should sit correctly in the rim.
Check the tyre bead regularly to ensure that it is seated in the rim. Check that the tread pattern is free of
foreign bodies and that the valve protrudes straight out of the rim.
Damaged or worn tyres should be replaced immediately. Take your A2B to a dealer or qualified bicycle
mechanic to have the tyres replaced if necessary.
In the unlikely event of a puncture, you should be familiar with the correct procedure for removing and
replacing the front and rear wheels.
6.2.1 Cleaning the display
Do not use any cleaning agents such as benzene, thinner, acetone or similar agents for all cleaning processes.
Do not use abrasive or aggressive cleaning agents. Instead, use only commercially available household cleaning
and disinfecting agents (isopropanol) instead.
6.2.2 Cleaning the engine
The motor of your pedelec should be cleaned regularly from dirt, preferably with a dry brush or a damp (not
wet) cloth. Cleaning must not be carried out with running water such as a water hose or even a high-pressure
cleaner. However, driving in the rain and on wet roads is no problem.
Penetrating water can destroy the engine. When cleaning, always ensure that neither liquids nor moisture
penetrate into the motor.
Do not clean the engine while it is warm, e. g. immediately after a trip. Wait until he's cooled down. Otherwise,
damage may occur.
If the motor is removed, e. g. for cleaning purposes, it must never be attached to the cables or transported,
otherwise there is a risk of cable breakage.
If the motor has been removed from the frame of the pedelec, the plug of the motor and the socket of the
cable to the battery pack must be checked or cleaned for possible contamination before assembling.
7 Transport
When transporting the pedelec with a car, the following instructions must be observed:
Protect all components of your pedelec from wetness and dirt by taking appropriate measures.
Remove the battery before attaching the pedelec to the wheel carrier of your car. This also reduces the weight,
which you have to lift especially with a roof rack system.
Always transport the battery in the boot of your car.
The battery should also be removed when transporting indoors (e. g. in a station wagon) to prevent damage
during loading and driving.
For carrier systems with downpipe clamping, ensure that the battery mounting rail is not crushed/damaged
when the clamping device is tightened.
Make sure that the cable ends cannot cause damage to the pedelec or your car while driving.
After driving, check all pedelec contacts for possible foreign bodies or wetness. In order to ensure safe
functioning, all plug connections in particular must be free of dirt and foreign bodies and completely dry.
Never place your pedelec on the side of the gear shift during transport, for example in the boot of a car. This
could damage it.

8 Warnings
If not in use, do not expose your pedelec to strong sunlight. As a result,
the engine heats up and in extreme cases the full power cannot be delivered. Plastic parts also age more quickly
under intensive sunlight.
If there is a system standstill due to increased temperatures (e. g. caused by uninterrupted driving or
permanent direct sunlight), allow the engine to cool down for about 10 minutes before continuing your journey.
