Introduction
You have decided in favour of a Pedelec (Pedal Electric Cycle) - a bicycle that is
equipped with an electric hub drive motor to give you additional assistance
when riding.
With this bicycle, you can make better progress in headwinds, when
transporting heavy loads or on steep slopes.
You can select the level of power assistance required according to the weight of
your load and/or the prevailing road conditions, the effectiveness of the power
assistance depends on your pedal power and the level of assistance selected.
Before switching on the electric assistance system, please read the chapter
“Charging the battery”. The battery must be fully charged before you go for a
ride the first time.
Mode of operation and extent of electronic power assistance
As soon as you turn on the electric assistance system and begin pedalling or
pushing the throttle, electronic power assistance is available. Depending on the
selected assistance level the motor will add a certain amount of power to assist
you. The amount of support is also proportional to the force pushed into the
pedals thanks to the torque sensor integrated into the crank axle.
An average rider can easily reach on flat tracks up to 80km out of the standard
13Ah battery.
Levels of support
There are currently five support levels:
1 = 20%, 2 = 40%, 3 = 60%, 4 = 80%, 5 = 100%
With higher support the motor will reach also a higher speed.
What comes with the bike?
•240V mains charger
•Manual
Optional accessories
•Rear carrier: lightweight and sturdy alloy carrier suitable for pannier bags
•Mudguards
•PowerBuddy: a 12V direct charger. Allows charging your battery through
your car or RV battery without an additional inverter.
•Powerful rechargeable LED front and rear lights

Basic Safety Tips
Always pull the brakes and hold the handlebar firm and
straight before taking off to make sure you stay in control of
the bike when power assistance is in action! Also, keep in
mind that the left-hand thumb-throttle is active when the bike
is turned on.

For your road safety
●Always wear a suitable bike helmet
●Wear bright clothing or reflective elements
to be seen better by other road users
●Wear shoes with a non-slip sole
●Wear close-fitting clothing on your legs or
wear trouser clips
●Wear bicycle gloves
How to use your charger
Your infinity comes with a 3Ah quick charger to charge your battery. Please do
not use any other charger.
The typical time to charge an empty 13Ah battery is about 5 hours.
If you want to charge your battery from a car or motor home
(12V systems), NZEBIKES or your retailer can supply a special
charger called PowerBuddy for this purpose.
Before you use the charger the first time please read the following notes
regarding safety carefully!
•To prevent any possible injury, this charger should only
be used for the original lithium battery which is supplied
together with the infinity e-bike
•Any other battery is not compatible and risks to explode
while charging, causing serious injury to people as well
as damage to other equipment
•Please make sure that the charger is always kept dry
and does not get wet at any time.
Should there be an incidence of contact with water or any other liquid, make
sure to unplug the charger immediately from the power socket and have it
inspected by your dealer.
Please make sure the charger is always placed on a flat surface when in use.
Also, make sure that the charger is always unplugged and removed from the
6
Ref (1)
power socket when not in use.
Before using the charger, always make sure that the plug and the cables are
not damaged.
Never connect a damaged cable or plug to the power socket. Never try to
disassemble the charger. There are no serviceable parts in the charger.
Always unplug the charger before cleaning it. The charger should only be
cleaned with a dry cloth. Never use a wet cloth, oil or any other liquid.
The charger LED (1) indicates the battery status:
LED STATUS
green the battery is not connected
red the battery is charging
green the battery is charged, the charger has switched off
Before using your e-bike the first time, the battery has to be
charged once overnight for at least 12 hours.

Safety notes concerning the battery
•Keep the battery out of reach for children
•Never try to open the battery. Apart from this being
dangerous, all warranty will be void
•Remove the battery from the bike when transporting on
an external bike rack
•Do not dip the battery in water or any other liquid
•Do not keep the battery close to heat or open fire
•A battery needs to be recycled after use, never throw it
in an open fire as it could explode
•If the battery is damaged because it has been dropped
or because of a biking accident, there might be a risk of
an internal short-circuit. Immediately stop using a
damaged battery.
To maximise the use of this battery, please consider the following:
The battery will not charge when exposed to temperatures below +0°C or
above +60°C. It is therefore recommended to keep the battery at room
temperature before charging it.
The charger operates with a microcomputer system with automated control
functions. It automatically stops charging when the battery is full. It cannot be
damaged by overcharging.
None the less, we strongly recommend to always disconnect the power plug
from the wall socket after the battery is charged as power surges, i.e. lightning,
through the grid can damage the charger or battery electronics!
When storing the battery for a longer time period, (>3 months, e.g. over
winter) it is important to place it in a dry and cool place. Furthermore it is from
advantage to have the battery only at about 80% charge. There is usually no
need to recharge the battery.
Li-Ion batteries have the chemical property to create small amounts
of gas if stored for a longer time period with 100% charge. This will
affect the capacity and life time. From a technical point of view it is
therefore better to store Li-Ion batteries not fully charged.
8
Charging the battery
You may charge the battery on the bike or remove it to a
more convenient place.
1. Open the plug cover at the right side of the battery (#5)
2. Connect charger cord to the battery
3. Connect the power cord to a mains socket
The charger will get hot during charging – do not cover while
in use as it might cause a malfunction.
How to remove and insert the battery
1. Removal: unlock the battery lock at the left side of the battery
2. Slide battery upwards and then lift it out of the rail
3. Insert: Slide the battery into the battery rail, secure it in the frame with
the battery lock
Before starting to ride
Mount or dismount front wheel
For easy transport, you may remove the front
wheel using the quick release at the front wheel
axle.
To remove the wheel flip the lever into the open
position. Now hold the lever and turn the bolt
on the other side about 8-9 times to loosen the
axle – do not remove the bolt! You should be
now able to lift the wheel out of the fork.
To mount the wheel repeat procedure the other way round. Guide the rotor in
between the brake pads. Hold the lever pointing parallel to the fork in the open
position (downwards), turn the bolt till you feel a slight resistance. Try to close
the lever – if it is too hard to do so, loosen the bolt a bit and try again.
Before every ride make sure the quick release is tightened
properly. To fail so can lead to serious injuries!
Never squeeze the brake lever without the wheel fitted!
9
Adjust seat height
Open the quick-release lever at the seat clamp, adjust the seat height and close
the lever firmly. If the lever is too loose, open the lever again and turn the
adjusting nut clockwise until you feel resistance. Now close lever again. It
should close with noticeable resistance.
Never tighten the seat post if the maximum mark is visible,
otherwise, you can injure yourself or damage the seat post.
How to find the correct saddle height?
1. Sit on the bike saddle
2. Try to reach pedal with your heel when it is in
the bottom position. Your knee should be
more or less fully straightened out
3. Place the ball of your foot on the centre of the
pedal. If your knee is now slightly bent, the
saddle height is correct
Adjusting the saddle angle
Best riding comfort is found when the saddle is horizontal, some riders prefer a
slight forward angled seat.
Never angle a seat back
as it can quickly lead to
back pain or physical
injuries
1. Loosen the clamping screw anti-
clockwise
2. Tilt the saddle to the required angle
3. Tighten the clamping screw
clockwise. Make sure that the screw
is tightened firmly (20 NM)
10
Adjust the stem and handlebar
The angle of the stem can be adjusted by opening the
6mm Allen Key screw at the right side of the stem. Do
not remove the screw! There are
two clamp plates, as soon as both
are release you may adjust the
angle. Re-tighten properly!
Adjust the tilt of the handlebar by opening two of the
handlebar clamp screws (upper or lower, 5mm Allen Key).
Chec tire pressure
It is very important to maintain the correct tire pressure. Too low pressure will
decrease the range and can lead to rim or tire damages when riding over
kerbs. The recommended tire pressure is 40 psi. For muddy undergrounds, the
tire pressure can be reduced to improve traction.
Suspension for
Your infinity mountain bike is equipped with a high-
performance air suspension. This fork allows the rider to
adjust the suspension to their riding style and terrain.
The pressure of the air-cartridge can be adjusted on the left
side by adding or releasing air pressure. A special pump is
required for this purpose – your local dealer can help you
with this. The pressure should be set according to the weight
of the rider.
Lock Out Lever
The right side lever allows to lock the oil cartridge. If
the lever is turned clockwise any fork movement will
be prevented. When going uphill it is usually better to
lock your fork to prevent fork pumping.
Rebound Control
A rebound control knob can be found at the bottom of
the right fork leg. For slow and bumpy rides adjust to
(+) for fast rides that need good brake control choose
a faster rebound setting (-).
11
Operation
•Turn on the e-bike electronics by pushing the (l) button for 2 sec
•Select the desired assistance level with the (+) or (-) keys. Start riding.
•Use the throttle as desired to add additional power to the selected
assistance (the throttle does only add power according to the selected
level, this is a safety measure)
•When finished riding press the (l) button for 2 sec to turn the system off
(it will also turn off after 5 min when not used)
Display Operation
BATTERY STATUS
The display shows the battery level with 10 segments and the real voltage. If
the battery reaches the red zone, the controller or battery might turn off when
a higher load is applied, i.e. riding uphill.
POWER DISPLAY
In the upper left area a bar segment display shows how much current the
motor is drawing from the controller. This allows the rider to see how efficient
he or she is riding, less bars means the battery capacity will last longer.
KM/H: Shows your current riding speed
12
ASSIST LEVEL: Your selected level of assistance. 0 = no support, 5 = max
support
MODE BUTTON: Toggles the display information. Shows ODO, trip time, max
speed, average speed and your trip distance.
TRIP: accumulates until manual reset. To manually reset push the (+) and (-)
keys together for >2 sec.
TIME: The total trip time
Walk assistance: you can activate the motor to support you pushing the bike
up a hill. Press and keep depressed the (-) button. After 2 seconds the motor
will start with a maximum speed of 6kph.
Walk assistance is not supposed to be used while riding the
bike
Throttle
The left hand side thumb-throttle allows the rider to add power to the selected
assistance level. This can be useful when starting or to give you an extra boost
when riding up a hill.
Gears
Only change gears while pedalling otherwise the derailleur
might get damaged
If you have to change gears, i.e. to start
in first gear, lift the rear wheel using the
side stand and turn the crank while
changing the gears.
As a rule of thumb gears on a bike are
changed and used similar to a car with a
manual gearbox.
You will start in 2nd gear, on a flat road
you will choose gear 6 or 7 to pedal
along. Uphill go back to 3 or for steeper hills gear 1. If you ride faster or
downhill choose higher gears.
The assistance level chosen on the display will assist you up to a certain speed.
Choose the assistance level and gear according to your needs and riding style.
Watch your crank revelations, if you have the feeling you have to push too hard
13
at too low revelations, change to a lower gear. If you pedal very fast with less
effort, choose a higher gear or reduce the assistance level.
When you intend to stop it is good practice to change the
gear back to a lower gear so you may start without any
problems. This can easily be done while braking and slowly
pedalling as the motor will not push you further.
Bra es
We recommend always using both brakes at the same time – this allows the
rider to take the best control over the braking process without stressing the
front or rear brake. To brake efficiently, your front brake is there to stop you
and the back brake is there to shave off speed. Roughly 70-80% of your
stopping power comes from the front brake. Leaving 20-30% for the back
brake.
Please note that this bicycle uses high performance hydraulic
brakes with no special motor cut-out. When going around
narrow corners adjust the power support to prevent
unexpected high acceleration.
aintenance
Your infinity e-bike needs regular maintenance as any other normal pushbike.
All bike shops can help you with these maintenance steps.
There is no maintenance necessary of the electrical components.
Bra es
This bike uses high performance hydraulic brakes which are self-adjusting. If
you feel that the brake force gets lower or you hear unusual noises then most
likely the brake pads have to be replaced. Please see your local bike shop.
Gears
Our infinity bike uses a solid and easy to maintain
Shimano Deore gear system.
It can happen after a while that gears do not
perfectly change anymore or you experience a
rattling noise while pedalling. This is normal due
to the nature of the used control wire hulls which
can get compressed over time. To re-adjust it is
usually enough to slightly tighten the gear wire.
14
For the rear derailleur turn (A) anti-clockwise while turning the pedals till the
rattle goes away.
Safety points
We recommend a 12-month interval service or every 1000 km.
Important checkpoints are:
▪Quick-release front axle
▪headset
▪stem clamp
▪bottom bracket and crank
screw
▪rear wheel axles nuts
▪seat post clamp
▪brake caliper screws
▪spoke tension
Spoke tension has to be checked on a regular interval. Failing
can cause spoke breakage and will void the warranty
Repairing a puncture
With the motor in the rear wheel, it is more complex to replace a tire or tube.
In case of a puncture, we first recommended to check if the puncture can be
repaired using a patch.
1. Lay bike on the left side side
2. Pull tire of rim
3. Identify the puncture in tube and check tire for any sharp objects to be
removed
4. If the tube is still repairable apply a patch
5. Refit and pump up the tire
To remove the rear wheel, first, unplug the motor cable at the right side of the
chain stay. When assembling make sure the arrows on the plugs are aligned
and the plug is entirely plugged in. If you get Error 8 on the display, unplug
and try again.
15
Troubleshooting
Problem Resolution

Glossary
BMS
BMS is an electronic circuit for battery monitoring. It increases a battery pack's
safety by making sure that all cells are operated within the permitted voltage
range only. When current is too high, the temperature is too high or one line of
batteries inside the battery is outside the permitted voltage range the charge
output will be switched off. This avoids the total discharge of the battery during
normal operation. An integrated balancer ensures that any differences in
voltage between single cells are equalised. In case of a problem with the
charging device, the BMS makes sure that the battery cannot be overcharged.
A capacity gauge may be included to display the remaining capacity.
Controller
The controller is the heart of any electric bicycle. It has the power electronics
to drive the motor and a microprocessor. The controller processes all input
signals coming from the different sensors and it talks to the display on the
handlebar. The microprocessor runs the firmware, which is the piece of
software telling the controller what to do. Firmware updates can be applied to
improve or add functions.
Display
The display is usually mounted to the handlebar and allows the rider to readout
vital information about the e-bike system and control the functions in the
controller. There are different kinds of controllers with LED or LCD interfaces.
Hall sensor
Hall sensors are used in motors, cadence sensors, brake switches, and power
throttles. Inside the motor, they determine the motor direction and submit it to
the controller so the motor will turn in the right direction right at the start.
Inside the PAS they detect if the magnet disc is rotating. Inside the power
throttle, they measure how far the throttle is rotated. Hall sensor can be of the
analogue or digital kind. Functional principle: When hall sensors are passing by
a magnetic field they emit an initial voltage, which is proportional to the
product of magnetic field strength and current (Hall Effect). They are named
after their inventor Edwin Hall.
17
Pedal Assist Sensor (PAS)
In an electric bicycle, the PAS measures if the crank is moving in riding
direction. This information will be passed on the controller which then activates
the motor to support the rider. The PAS can distinguish between forwards and
backward movements of the crank.
Torque Sensor
By measuring the amount of force the rider applies to the pedals the torque
sensor signals without any delay to the controller how much support the motor
has to add. This creates are very responsive but at the same time smooth
riding experience. Torque sensors are mostly placed in the crank, with or
without the motor. They are more expensive to build than PAS sensors.
