Introduction
Thank for choosing a Wisper electric bicycle.
By making the decision to use an electric bike you are helping to safeguard our
environment by saving our planet’s precious resources and reducing carbon pollution.
Before you use your Wisper bike it is important that you read this manual carefully. If
there is anything you do not understand completely please contact us.
Please observe traffic regulations, and don’t lend your bicycle to anyone who is
unfamiliar with it. The bicycle can only legally be used on the road by a person aged 14
years or older.
We strongly advise you to always wear a cycle helmet when using your bicycle and if you
are unfamiliar with cycling to attend a cycle proficiency course prior to using it. Your
Wisper Works 906Alpino is not toy and should be considered a serious mode of
transport.
As with all bicycles it is important that you stay within safe limits, if you feel as if you are
traveling too quickly for the road conditions you probably are so slow down.
Test your brakes prior to using the bike every time you use it and remember the bike will
not stop as quickly in wet or icy conditions as it would on a dry road.
Before you use the bike for the first time you must make absolutely certain that it has
been correctly built. You can do this by either taking it to your nearest cycle engineer or
if you are proficient in cycle mechanics inspecting it yourself. In particular you must
make sure that the pedals, saddle, handle bars and any self assembly items have been
correctly fitted.
NEVER drink alcohol and ride your electric bike. The use of alcohol greatly reduces
reflexes and limits your ability to ride safely. Even a very small amount of alcohol will
limit your ability to be safe on the road.
Always wear an approved cycle helmet.
When you need to replace your battery please either dispose of it properly or preferably
send it back to us or our distributors and we will make sure it is properly recycled.
Happy cycling!

3.1 Before you use the battery for the first time it is best to give it a full deep charge
for 12 hours. To fully condition your new battery give it complete deep charge,
discharge cycles for the first three charges. This is achieved by charging your
battery for 12 hours and then using the bike until the battery is completely
drained. After this “conditioning” process you can then charge and discharge
the battery as and when you require for long or short periods.
3.2 If you are going to leave your battery uncharged for more than eight weeks it is
best left half charged. You should then re charge it every four weeks for two
hours to keep it in top condition.
3.3 Before setting off on any journey it is always better to have a fully charged
battery
3.4 Always remember that you use up to three times more power when setting off
under the twist throttle. To preserve the life of each charge always set off using
pedal assist

9 Battery on off and battery lock
9.1 Your Wisper bike has 1 set key. The key for turns the
battery on/off and locks the battery in the bike. Please
keep a careful note of the key numbers as we cannot
replace them without these numbers should they
become mislaid.
9.2 The battery is connected to the electrical system of the
bike automatically when you slide the battery into the
frame. To turn on the bikes electrical system, turn the
key in the battery clockwise, to turn off the power turn
the key anti clockwise.
9.3 When the battery has been turned on the bike is now ready for use. The
ON/OFF button on the handle bar display unit isolates the power from the bike,
when the bike is “on” you will see the LCD display illuminated. When the
ON/OFF button is pushed and the LCD shut down you have turned the bike “off”.
When the bike is “off” you will not get any assistance from
the battery and motor and the bike is effectively simply an unpowered push
bike.
9.4 To lock the battery into the bike frame turn the key clockwise the locking bolt
holds the frame, if you want to turn the battery power on, turn clockwise again,
if you want to unlock press the key and turn the key anti clockwise while the key

10 LCD function description
10.1 The LCD display has the following functions (Refer to picture below).
A: Power ON/OFF button. For details refer to the paragraph below.
B: Up (increase) adjusting button. For adjusting the pedal assistance strength,
and back light brightness.
C: Down (decrease) adjusting button.
D: Set. When pressed, you can set the back light of the LCD and the

- 11 -
single trip distance. If you press it together with C button, you can set the bike’s
tyre size.
E: This shows the instant power consumption extent. A longer bar means the
motor’s output is higher.
F:
Battery capacity. Three bars indicate 80% capacity left, two bars indicate 70%
left, one 55% capacity left, half bar 5% capacity left.
G: Instant speed figures.
H: Pedal assistance strength levels.
I: Total riding distance since last reset.
10.2 When the ON/OFF button is pushed and the capacity indicator goes out you
have turned the bike “off”. When the bike is “off” you will not get any assistance
from the battery and motor and the bike is effectively simply an unpowered
push bike. To turn the power back on so the pedelec and throttle work again
simply press the ON/OFF button once, the capacity indicator will illuminate
showing the power is on.
10.3 How to adjust functions:
10.3.1 How to adjust the pedal assistance. Refer 12.2, 12.3 and 12.4
paragraphs.
10.3.2 How to adjust the back light of the LCD. Press the “set”button once, you
will see a light symbol added under the battery capacity indicator,
then press the “up arrow”to turn the back light on. The more times you
press the brighter back light you will get. Refer to above picture.
10.3.3 How to read the single trip distance. Press the “set”button twice; you
will see a symbol in the left side of the screen.

- 12 -
10.3.4 How to read the single trip riding time. Press the “set”button three
times; you will see a clock symbol in the left side of the screen.
This display does not provide the time of day –simply elapsed riding
time since last reset.
11 The LIGHTS
11.1 The front light is an automatic sensor light.
When you turn the power on, it checks the
brightness of the surroundings. It will light
when you ride the bike in low light conditions.
It will turn off after 30 seconds when the
ambient light increases.
11.2 The rear light is also automatic. The sensor
point is from front light.
12 Pedelec mode and ASSIST
mode
12.1 When you first ride your 906Alpino you will notice that after one turn of the
pedals the motor will start working assisting you ride the bike by adding power
to the front wheel. This is the standard or pedelec mode, to continue using the
pedelec mode you must keep turning the pedals, if you stop the motor will stop
and the bike will slow to a halt. If you start pedaling again after one turn the
motor will start again.
12.2 You will find the ASSIST level shows on the LCD display. You can adjust the
assistance strength by pressing the up or down arrow. There are 6 levels of
assistance（40%/50%/60%/70%/90%/100%）.
12.3 70%, 90% and 100% mode are generally used when you need a greater amount
of assistance from the motor. 60% mode is used when you do not need the
instant power of 90% or 100%. 40% and 50% are used in high traffic situations
or poor conditions such as ice and snow when 70%, 90% and 100% power
immediately could be dangerous.
12.4 Power consumption. When you increase the assistance, you will find the battery
range is reduced
13 Throttle
13.1 The throttle can be used independently to the pedelec mode but the operation
will vary depending on the country where the bike is supplied. Bikes are set up
to be legal in the region in which they are supplied and will either provide full
power (100%) or power up to 4 mph (6kph) (walkalong mode) independently of

- 13 -
the pedelec.
13.2 The independent use of the throttle, when available, will enable you to use the
throttle without pedaling. However to achieve optimum performance and life
from the motor it is recommended that large throttle openings from rest be
avoided and that where possible pedal assistance should be used when starting
the bike from rest.
13.3 The use of the throttle in pedelec mode is legal in most countries. Throttle in
pedelec mode enables you to turn up the power to the motor as long as you are
pedaling the bike, if you stop pedaling the motor will stop too. If you have the
pedelec mode set too Low, you can increase the assistance from the motor from
40% to 100% of available power simply but turning the throttle towards you.
IMPORTANT Make sure your throttle grip and the grip on the left hand side of your
handle bars are always intact, in good condition and on the bike. Uncovered handlebar
tubes can be very dangerous in case of a collision. Ensure the spacer fitted between
the throttle and the grip is properly installed
14 Brakes
14.1 Front: Disc Rear: disc
14.2 The brakes on your Wisper bike are fitted with cut outs which are required by
law. This means that when you pull on either the back or front brake lever the
motor immediately stops working.
14.3 Details of how to adjust and maintain your brakes are as follows:
Once a month, inspect brake pads and blocks for wear. If they have reached the
wear limit then replace the items.
Front disc:
Mechanical disc brakes offer several advantages over traditional rim brakes
better braking in wet, muddy or other adverse conditions, less braking power
fade over extended downhill braking and the ability to continue braking even if
your rim becomes bent or distorted.
14.3.1. Adjust the pads and caliper
14.3.1.1. Use a 3mm Allen wrench to
adjust the stationary caliper
adjusting bolt at the back (hub
side)of the caliper. Adjust the bolt
so that there is 0.3mm clearance
between the stationary (hub side)
pad and the rotor.

- 14 -
14.3.1.2. Adjust the cable tension to
the desired modulation by
tightening/loosing the tension
modulation adjuster bolt on the
caliper with 5mm Allen wrench
14.3.1.3. Adjust the cable adjuster bolt
on the caliper so that there is
0.3mm clearance between the
outside pad and the rotor. Turn
this bolt in a clockwise direction
to provide more clearance, and
anti-clockwise for less
clearance.
14.3.2. Removing and installing pads.
Caution: The pads and rotor must be kept clean and free from oil or grease
based contamination. If the pads become contaminated you must discard
them and replace them with a new set. A contaminated rotor should be
cleaned with brake cleaning solvent and dried.
14.3.2.1. Unscrew caliper’s two screws fixed in front fork. Pads can be
removed by releasing the pin which goes through the pads and then
manoeuvering the pads out of the rotor slot. Straighten the pin or
replace with a new item if damaged.
14.3.2.2. Holding the pad end-tab, insert it into caliper slot with its
metal backing towards the piston. Make sure the hole in the metal
backing goes over the piston pins. When correctly inserted, the pad
will be held in place magnetically, repeat for the other pad following
the reverse procedure.

Rear brakes:
14.3.3. Adjust the pads and caliper
14.3.3.1. Use a 3mm Allen wrench
to adjust the stationary caliper
adjusting bolt at the back (hub
side) of the caliper. Adjust the
bolt so that there is 0.3mm
clearance between the
stationary (hub side) pad and
the rotor.
14.3.3.2. Adjust the cable tension to
the desired modulation by
tightening/loosing the tension
modulation adjuster bolt on the
caliper with 5mm Allen wrench
14.3.3.3. Use a 3mm Allen
wrench(Refer to picture) to

0.3mm clearance between the
rotor.
14.3.4. Removing and installing pads.
14.3.4.1. Unscrew two caliper
screws fixed in the rear fork.
Remove the clip(Refer 14.3.3.1
picture), and then unscew the
bolt shown in the picture. Then
manoeuver the pads out of the
rotor slot.
14.3.4.2. Holding the pad end-tab,
insert it into caliper slot with its
metal backing towards the
piston. Make sure the hole in the metal

- 16 -
backing goes over the piston pins. When correctly inserted, the pad
will be held in place magnetically, repeat the procedure for the
other pad.
Warning: If you are unsure about any part of the installation process you
should seek advice from Wisper service center or qualified mechanic.
15 Stem handle bar clamp
15.1 Your bike has been fitted with a quick release handlebar clamp that allows you
to change the position of the bars quickly and easily to find the most
comfortable riding position.
15.2 The stem and handle bars need to be fitted before you use the bike.
15.3 To fit, insert the stem into the front tube at least to the position of the
“Minimum insertion” mark.
15.4 Tighten the quill bolt and fix stem.
14.5 Push in the direction of the arrow slide cap 1 and lift lever 2.
