Introduction and Purchaser Responsibilities
Thank you 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 you must read this manual carefully. If there is anything
you do not understand completely please contact Voltage Bikes Ltd or your bike dealer.
The statements below set out your responsibilities as the owner/rider of an electric bike.
It is your responsibility as a cyclist to obey all relevant federal and provincial laws and
regulations that apply to the operation of a power assisted bicycle. The laws that apply to a
power assisted bicycle are similar to those for a normal bicycle. However, there are some
minor variations. For example, in British Columbia, the bicycle can only legally be used on
the road by a person aged 16 years or older. In addition, an approved bicycle helmet must
be used when riding.
If you are unfamiliar with cycling, we recommend that you attend a cycle proficiency course
prior to using your electric bike. As with all bicycles it is important that you stay within
safe limits and adjust your riding to match conditions; remember the bike will not stop as
quickly on wet or icy surfaces.
It is the rider’s responsibility to ensure they are in proper physical condition to ride a Wisper
electric bicycle.
The bicycle must be assembled by a person competent in bike mechanics. None of Wisper
Bikes Ltd, Voltage Bikes Ltd or any of its distributors, accept any legal liability for accident or
injury caused by improper installation of any of the components utilised on this electric
bicycle. If you are not fully competent with bicycle maintenance and tuning procedures,
you must have your bike checked over by a qualified bicycle technician before riding it.
The rider is responsible for inspecting and making sure the bike is in safe working order
prior to riding each time. Before each use of your bike you should:
1) Check the handle bars and handle bar stem are properly tightened;
2) Check all other nuts and bolts and fixings are properly tightened, pay particular
attention to the motor fixings, wheel nuts, side kick stand, yoke and steering head

- 4 -
bearings;
3) Check brakes and brake isolators are functioning properly;
4) Check tire pressures are 60psi / 4.1bar and tires are not damaged;
5) Check reflectors and lights (if fitted) are functioning properly;
6) Make sure battery is fully charged;
7) Load battery into bicycle and turn on with key;
8) Check the power indicator lamps are illuminated on the left hand side of the handle
bars. If they do not illuminate press the on / off switch once;
You must take your bike in to be serviced and checked by a qualified bike mechanic before
300km of riding or within three months, whichever occurs first. This is standard good
practice for any new bike, and particularly important for an ebike with the extra loading
placed on the wheels. The service must include spoke tensioning for both front and rear
wheels.
Wisper bikes are not mountain bikes and should not be ridden as such. The bikes should
not be jumped, ridden on terrain which causes significant jarring, or in areas where the
motor or other electrical components are likely to become submerged.
Wisper offers a warranty on its bikes purchased from a Wisper dealer (see the owner’s
manual for details). To validate the warranty, the retail customer must register the bike at
www.wisperbikes.com under the warranty menu within 14 days of purchase. The
warranties will only be valid if the procedures set out in this manual are followed. For
example, when not in use for long periods (e.g. over winter), the battery must be topped up
periodically.
Operating an electric bicycle involves risk and danger which can result in serious bodily
harm and injury to the rider or to other persons or property. These risks are potentially
greater than the risks associated with riding a non-electric bicycle, due to the additional
power supplied by the electric motor.
The purchaser/rider assumes all risks associated with operating the Wisper electric bicycle
and fully assumes and accepts responsibility for all losses, cost and damages as a result of,
or relating to, the operation of the electric bicycle including, without limitation, personal or
third party injury or harm, and property damage or economic loss suffered by the
owner/operator or by any third party.
Happy cycling!
Wisper Ltd

Part 1 Caring for your Wisper bike and checks
Although your Wisper bike has been thoroughly tested prior to delivery, it is very important
that you check the bike thoroughly before its first use. Equally important are frequent and
regular spot checks they will protect you and your Wisper bike.
Please read this manual carefully. Only on full understanding of all the functions of this
electric bicycle should you attempt to use it.
Your Wisper bike has been transported in a strong seven-layered corrugated carton. To save
space it has been delivered with the front wheel, handlebars, seat post and seat, rear rack
and pedals ready for assembly with the tool kit provided.
* Rack not supplied on 905se sport model
** Your retailer may have assembled your bike for you, if not you will find fitting
instructions on the Wisper website www.wisperbikes.com
1 Before you set off for the first time
1.1 Check the handle bars and handle bar stem are properly tightened
1.2 Check all other nuts and bolts and fixings are properly tightened, pay particular
attention to the motor fixings, side kick stand, yoke and steering head bearings
1.3 Check brakes and brake isolators are functioning properly
1.4 Check tyre pressures are correct and tyres are not damaged
1.5 Check reflectors and lights if fitted are functioning properly
1.6 Make sure battery is fully charged
1.7 Load battery into bicycle and turn on with key
1.8 Check the power indicator lamps are illuminated on the left hand side of the

- 6 -
1.9 To avoid dangerous unplanned acceleration, always make sure that the electrical
system is turned off and the power indicator lamps are not illuminated when
mounting, dismounting or leaving the bike unattended. For your safety, please turn
off the power key on the battery when stopped or walking the bike
1.10 Remember to validate your warranty by visiting
http://wisperbikes.com/Warranty-Registration-Form.php and filling in your details.
2 Before each use
It is important you perform a quick check of your bike every time you use it. Checks should
include the following (if you do find any damage or problems do not use the bike until the
problem has been solved or you have had the faulty item checked by a bike mechanic or
your retailer).
2.1 Check tyres for any visible damage
2.2 Check tyre pressures
2.3 Check for any loose nuts bolts or fixings
2.4 Check brake functions
2.5 Check electronic functions
2.6 Check reflectors are in place and lights are working
2.7 Check your battery for any visible signs of damage
3 Battery care
3.1 Before you use the battery for the first time it is best to give it a full charge.
Your battery is charging when the orange light is lit on the charger unit (you can
also usually hear the fan operating). If the orange light is not lit, try switching the
power switch on the charger unit on and off to allow the unit to ‘read’ the battery.
To condition your new battery, you should complete three ‘shallow’ discharges i.e.

- 7 -
discharging to about 3 of 4 green lights showing before recharging. After this
“conditioning” process you can then charge and discharge the battery as and when
you require, although we recommend keeping it topped up.
3.2 A lithium ion battery will slowly discharge over time as it sits in storage. If a
battery is allowed to fully discharge, this will stress the cells in the battery and
reduce the capacity and life of the battery. During normal riding, the Wisper
batteries have a battery management system (BMS) which switches off the
electrical system when the voltage drops to a certain point i.e. the battery is not
allowed to fully discharge and the cells are protected. However, the BMS will not
prevent a battery from slowly discharging as it sits in storage. Therefore, it is
important to ensure that your battery retains some charge over the winter months.
Unfortunately, it is also not ideal to put your battery in storage with 100% charge as
this can put some stress on the cells. The following actions are therefore
recommended for battery care:
Store your battery with a partial charge, ideally 40-80%. While charging, you
can check the number of green lights on the battery indicator (with the key
switched on) … aim for two-three lights (four lights is fully charged). Another
way of checking that the battery hasn’t reached full charge, is that the amber
light on the charger is still on and you can hear the charger fan operating;
Depending on how fully charged the battery was initially, it will normally take
about 1-2 hours to give the recommended partial charge;
If you end up charging your battery to 100% (the green light on the charging
unit comes on), go for a ride to discharge it partially before storing the battery;
Check your battery every couple of months of storage and give it a top up if the
battery indicator has dropped to one light;
Ideally, the battery should be stored in a cool place. Significantly elevated
temperatures over prolonged periods can reduce battery capacity. Also avoid
freezing the battery.
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.
3.5 Do not expose the bicycle or battery pack to fire, heat sources, acid or alkaline
substances.
3.6 When leaving your bicycle during hot weather always leave in a shaded well
ventilated area.
3.7 For best results always recharge the battery at room temperature.
3.8 Before unloading the battery make sure it is turned off at the key, then raise the
saddle and unload the battery using its handle.
3.9 If your battery is damaged or appears to be overheating for any reason immediately
return it to your retailer for advice and a safety check.

4 Recharging your battery
4.1 First connect the charger to the mains and turn the mains power on. Make sure the
charger is turned off (at the switch on the charger
unit) and connect the charger to your battery (refer
the recharge point picture). Finally, turn on the
charger. Red and yellow lamps on the charger
indicate the battery is charging, when the yellow
light turns green the battery is fully charged. Always
turn off the charger and disconnect from the mains
after charging. Always disconnect the charger from
the mains before disconnecting the charger from
the battery.
4.2 When charging the battery always do so in a well
ventilated area.
4.3 Do not leave the charger connected to the mains when not in use.
5 Water
5.1 Your electric bicycle is rain and splash proof.
5.2 The electrical components of the vehicle, such as motor, battery, and controller,
must not be submerged in water.
6 Maintenance and adjustments
6.1 IMPORTANT! Do not attempt to open the casings of the battery, motor or
controller it could be dangerous and all warranties will become void. If you
experience a problem contact our service department or your retailer.
6.2 Wheel spokes should be adjusted after 300 kms riding. Handlebar and saddle tubes
should never be raised beyond the maximum indicated by a safety line around the
tubes. The recommendation of the torque on the nuts as follows:
(A) Front axle nuts. 46N.M
(B) Back axle nuts. 70N.M
(C) Handlebar clamp bolts. Bolt 1:16N.M, bolt 2:10N.M (Refer 15.1 picture)
(D) Handlebar stem expander bolt. (18 to 20)N.M
(E) Seat pillar clamp nut/bolt. (5-8) N.M
(F) Brake cable anchor bolt. 5N.M
(G) Brake centre bolt. 11N.M
(H) Seat clamp nuts. 24N.M
(I) Crank nuts. R:42N.M L: 46N.M
(K) Gear shifter nuts. 4N.M
(L) V brake caliper nuts. 10N.M
(M) Rear carrier nuts. 8N.M

- 9 -
(N) Mudguard bracket nuts. 8N.M
Other nuts torque depends on the nuts volume. M4：2.5-4.0N.M M5：4.0-6.0N.M
M6：6.0-7.5N.M
6.3 Your bike has a rear derailleur that will automatically tension your chain. However if
the chain becomes loose or frequently comes off the front cog, you can easily adjust
the chain tension by loosening the rear axle nuts slightly, and adjusting the tension
bolts. Make sure that the chain runs freely and re tighten the axle nuts.
6.4 The brake levers should lock the wheels when compressed half way between their
open position and touching the handle bars.
6.5 Warning: Handlebar hand grips or tube end plugs should be replaced if damaged, as
bare tube ends have been known to cause injury.
6.6 Warning: Any replacement forks must have the same rake and same tube inner
diameter as the originals fitted to the bicycle.
6.7 Disc brake pad wear and replacement. Remove the brake
pads and check them for wear. If they have worn to the
point where the caliper piston pin-positioning hole goes all
the way through, then they need to be replaced.
IMPORTANT braking distances increase on wet or icy roads.
6.8 Lubrication:
6.8.1. Once a month: lubricate the chain, all pivot points on derailleur and derailleur
pulleys with chain lube. Also apply a light oil to the upper fork leg where the
lower leg slides on it. Wipe clean.
6.8.2. Every three months: lubricate the brake lever pivots and gears with light oil /
chain lube. Also lubricate the brake bushes (not the rubber brake shoes or
disc) with a little grease.
6.8.3 Once a year: have your dealer re-grease the bottom bracket bearings, headset
bearings, wheel bearings. Also, lubricate pedal axles where they thread into
the crank arms, handlebar stem.
6.9 Recommended tools for proper maintenance:
Torque wrench with lb•in or N•m gradations;
2, 4, 5, 6, 8 mm Allen wrenches
9, 10, 15 mm open-end wrenches;
15 mm box end wrench
Socket wrench and 14, 15, and 19 mm sockets;
T25 Torx wrench
No. 1 Phillips head screwdriver;

Part 2 Controls and Equipment
In this section we will describe the functions and any specific maintenance needed on all
the main controls and ancillary equipment.
9 Battery on off and battery lock
9.1 Your Wisper bike has one key. The key 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
misplaced.
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 bike’s 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 isolates the power from the bike, when the bike is “on”
you will see the battery power lights illuminate above the capacity indicator. When
the ON/OFF button is pushed and the lights go 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.
9.4 To lock the battery into the bike frame, turn the key clockwise and a locking bolt
will secure the battery to the frame. If you want to turn the battery power on,
turn clockwise again, if you want to unlock, press the key in and turn the key anti-
clockwise fully while the key is in lock position. (Refer to picture) Read 3 and 4 for
battery care and advice on charging at the beginning of this manual.
9.5 The battery can be charged either on or off the bike.
9.6 To remove the battery turn off the power by turning the key to position
“Unlocking” and raise the seat post to its maximum height. Using the handle on top
of the battery, lift out the battery.
9.7 To replace the battery reverse the procedure for removing it.

- 13 -
On the handle bars
10 The ON/OFF button
10.1 To turn the power on so the pedelec and throttle work simply press the ON/OFF
button once, the lights will illuminate showing the power is on. When the ON/OFF
button is pushed again and the capacity indicator lights go 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.
11 The LIGHT button
11.1 The LIGHT button can be found close to the ON/OFF button. If you press it when
the bike power is on, the LED headlight on the front fork will illuminate. Press it
again to switch off the light. The power for the light comes from the bike battery.
Due to the low power consumption, use of the light will not reduce your range. On
2011 bikes, the switch will also activate the rear light.
12 Pedelec mode and ASSIST button
12.1 When you first ride your Wisper bike you will notice that after one turn of the
pedals the motor will start working to assist you by adding power to the back 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 button on the panel on the handle bars with L.M.H (low,
Medium, High) with three LED’s (small lights) on 2010 bikes. For the 2011 bikes,
there are six levels of pedal assist and a zero level where the motor does not
engage. When the button is pressed sequentially the LED shifts between the
various pedal assist levels.
12.3 High mode is used when you need the maximum amount of assistance from the
motor. Lower modes are used in high traffic situations or poor conditions such as
ice and snow when higher power could be dangerous.

- 14 -
13 Throttle
13.1 The throttle can be used independently to the pedelec mode in some countries
such as the Canada, UK, Australia, and New Zealand. Check with your supplier if it is
legal in your region. Bikes are usually set up to be legal in the region in which they
are supplied.
13.2 The independent use of the throttle, when available, will enable you to use the
throttle without pedaling.
13.3 The use of the throttle in pedelec mode is legal in most countries. Throttle in
pedelec mode enables you to apply 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 below maximum, you can increase the assistance from the motor
to 100% of available power simply by turning the throttle towards you.
IMPORTANT Make sure your throttle and handlebar grips and the grip on the left are
always intact and in good condition. Uncovered handlebar tubes can be very dangerous.
14 Brakes
14.1 Your bike is fitted with disc brakes front and rear.
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 Regularly inspect brake pads for wear. Replace disc brake pads that are thinner than
1.0 mm. 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. On the disc brake use a 5mm 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) and the rotor.

- 15 -
14.3.1.2. Adjust the cable adjuster bolt on the
caliper So that there is 0.3mm
clearance between the outside pad
and the rotor.
14.3.1.3. Adjust the spring tension to the
desired modulation by
tightening/loosing the tension
modulation adjuster bolt on the
caliper with 2mm Allen wrench
14.3.2. Installing and removing 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 detergent solution, rinsed thoroughly and dried.
14.3.2.1. 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 the procedure for the other pad.
14.3.2.2. Pads can be removed by grasping the pad end-tab, lifting the pad
clear of the piston pin and then maneuvering it out of the rotor slot
in the caliper body.
Note: Disc brake pads are held in the caliper magnetically. No tools are required
to install or remove them. As the left and right pads are the same they maybe
inserted on either the left or right of the caliper.
14.3.2.3. Warning: If you are unsure about any part of the installation
process you should seek advice from Wisper service center or qualified
mechanic.

- 16 -
15 Handle bar stem
15.1 Your bike has been fitted with a angle adjusting
handlebar clamp that allows you to change the
height of the bars with a 5mm tool to find the
most comfortable riding position. A locking bolt
not shown in the figure is located underneath the
stem.
15.2 The stem and handle bars need to be fitted
before you use the bike.
16 The front connection box
16.1 The front connection box allows for the easy removal for repair
or replacement of any of the electronic components on the
handle bars. On the 2011 bikes, a simple plug and play manifold
makes removal even easier.
17 Quick release saddle height adjustment
17.1 Your Wisper bike has been fitted with a quick release saddle post collar to facilitate
the movement of the saddle to remove the battery or to change the riding position.
17.2 It is important that the nut on the collar is tightened so the post will not move in
the bike tube. Make this adjustment with the quick release lever in the open
position.
17.3 Adjust the seat to the correct height and close the lever. When you sit on the
saddle there should be no vertical movement at all in the saddle post.
18 Saddle post suspension
18.1 For your comfort your bike has been fitted with saddle post suspension it has been
set for a person weighing 75kg. If you are lighter than this you may not feel any
benefit and if you are heavier you may feel the suspension bottoming out.
18.2 The suspension post can be adjusted by removing the whole post with saddle
attached from the bike. On the bottom of the post you will find an allen key
adjuster. Simply turn it clockwise to tension the spring for heavier people and
anticlockwise to release tension for lighter people.

- 17 -
IMPORTANT never raise the saddle past the point where the maximum marks on the
saddle post are visible above the quick release collar
19 Rims and spokes
19.1 It is essential to get your spokes checked and tightened after 300 kms or three
months riding. If this service has not been undertaken at the correct time this may
cause damage to the wheels and spokes that will not covered under our guarantee.
20 Chain and drive wheel
20.1 The chain and drive wheel are made from rust proof materials.
20.2 Lightly oil with bicycle chain oil the chain at least once a month.
20.2 Because your bike has a rear derailleur the chain will be automatically adjusted.
