Please observe traffic regulations, and do not lend your bicycle to anyone who is
unfamiliar with it. In the UK the bicycle can only legally be used on the road by a person
aged fourteen years or older.
We strongly advise you to always wear an approved cycle helmet when riding your bicycle.
If you are unfamiliar with cycling, we advise attending a cycle proficiency course prior to
using your new bicycle on the public highway.
When using any bicycle, it is important that you stay within safe limits; if you feel as if
you are travelling too quickly, you probably are.
Always test your brakes prior to using the bike, and remember the bike will not stop as
quickly in the wet as it would in the dry!
Before you use the bike for the first time, please make absolutely certain that it has been
correctly assembled. 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 assembled items have been fitted
correctly.
Avoid consuming alcohol before you ride your electric bike. The use of alcohol greatly
reduces reflexes and limits your ability to ride safely.
If you need to replace your battery, please either dispose of it properly or preferably send
it back to us at Wisper or one of our distributors and we will make sure it is properly
recycled.
Above all, enjoy your Wisper bike, happy cycling!
Amps Electric Bikes Ltd
2. Caring for your Wisper bike and pre-use checks!
Your Wisper bike has been thoroughly tested at the factory prior to delivery, and
undergone a pre-delivery inspection by your Wisper stockist.
It is very important that you check the bike thoroughly before its first use. Equally
important are frequent and regular spot-checks, as they will protect you and your Wisper
bike. The bike should be returned to your supplier after approximately 300 miles/500 km
and have a second safety inspection completed.
Please read this manual carefully. Only on full understanding all of the functions of this
electric bicycle should you attempt to use it.

2.1. Before you set off for the first time!
2.1.1 Check the handlebars and handlebar stem are properly tightened.
2.1.2 Check all other nuts, bolts and fixings are properly tightened.
2.1.3 Check brakes are functioning properly.
2.1.4 Check tyre pressures are correct and tyres are not damaged.
2.1.5 Check reflectors and lights if fitted, are functioning properly.
2.1.6 Make sure the battery is fully charged.
2.1.7 Load the battery into bicycle and turn on with the switch located at the top left
hand side of the battery. (To remove the battery turn the battery key and hinge the
battery out to the right.)
2.1.8 Turn on the bike by pressing the on/off switch by the left hand grip for two
seconds. (Turn off the bike by repeating the same process).
!
The bike will be ready to ride and the LCD will activate showing battery state,
assist level, time, trip and speed. Exerting pressure on the pedals or twisting the
throttle will now activate the motor.
!
7

2.1.9 To avoid unplanned acceleration, always make sure that the LCD assist level is set
to 0 when mounting, dismounting and turn the bike off when leaving it unattended.
!
To set the assist levels, toggle with the + and – buttons
2.1.10 For full information regarding the XT-LCS W108 please refer to separate hand book
available from your Wisper stockist or Amps electric bikes.
2.1.11 Remember to validate your warranty by visiting www.amps.bike and filling in your
details under warranty.!
2.2. Before each use!
It is important you perform a check of your bike prior to each 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).
2.2.1 Check the tyres for any visible damage.
2.2.2 Check the tyre pressures.
2.2.3 Check for any loose nuts, bolts or fixings.
2.2.4 Check the brake functions.
2.2.5 Check the electronic functions.
2.2.6 Check the reflectors are in place and the lights are working if supplied.
2.2.7 Check the battery for any visible signs of damage.
2.3. Battery care!
2.3.1 Your Wisper bike comes with a high quality lithium ion battery. All lithium batteries
need to be looked after to ensure years of full use.
2.3.2 Recharge your battery after ever use if possible. Keeping your battery charged
extends it’s life and your bike is always ready to go.
8

2.3.3 You do not have to “condition” your battery by charging and discharging before it’s
first use. This was the case with old lithium ion technology but is not necessary on
modern batteries
2.3.4 Never leave your battery completely discharged for more than 24 hours. Voltage
dropping below minimum for any length of time will cause serious damage to your
battery cells.*
2.3.5 Recharge your battery every month even if you are not using the bike. Most lithium
Ion batteries will continue to discharge even when the bike and battery are turned off
(see above). If your battery falls below minimum Voltage it may not be recoverable.*
2.3.6 Do not expose the bicycle or battery pack to fire, heat sources, acid or alkaline
substances.
2.3.7 When leaving your bicycle during hot weather, always leave in a shaded well
ventilated area.
2.3.8 For best results, always recharge and store the battery at room temperature.
2.3.9 Before unloading the battery, make sure it is turned off and unload the battery
using its handle.
2.3.10 Further information on user responsibilities and battery maintenance are included
in the warranty section of this manual.
* The most common cause of battery failure the owner not keeping to points 4 and
5 above.!
Thisisthemostcommonreasonforcustomerstoneedtoreplacebatteries.Thisis
particularly noticeable in the spring when customers are using their bike for the
first time in the new year, this is when we get most calls about failing batteries. !
!
IMPORTANT!
If your battery is damaged due to your leaving it discharged, or not recharging
every month your battery is not covered by our warranty.
Battery safety
2.3.11 i. Never leave a battery connected to the charger or mains power over night.
ii. Never recharge a battery outside, in damp conditions or in temperatures
less then 0 degrees centigrade.
iii. Never open a battery case, try and fix the battery or give it to any one other
than a registered Wisper Stockist for maintenance. (Failure to
comply will void the warranty)
iv. If a battery is, or appears to be damaged or overheating for any reason, do
not use the bike and immediately return the battery to your retailer for advice
and a safety check.
IMPORTANT!
Ignoring any of the safety rules above could cause serious injury or fire.

2.4. Recharging your battery
2.4.1 Before charging, make sure the charger is turned off and connect your battery to
the charger at the charging socket. Plug the charger into a mains socket and turn on the
mains. A red lamp on the charger indicates the battery is charging. When the red light
turns green, the battery is fully charged. To optimise battery life, leave the charger
connected for a further hour and then turn off the charger and disconnect it from the
mains after charging. Always disconnect the charger from the mains before
disconnecting the charger from the battery. It is possible that the battery will take up
to twelve hours to charge on the first three charges.
2.4.2 When charging the battery, always do so in a well ventilated area.
2.4.3 Do not leave the charger connected to the mains when not in use. !
2.5. Water!
2.5.1 Your electric bicycle is rain and splash proof and can be used in all weathers.
2.5.2 The electrical components of the bicycle, such as motor, battery, and controller,
must not be submerged in water. !
2.6. Maintenance and adjustments !
2.6.1 IMPORTANT! Do not attempt to open the casings of the battery, motor or
controller. It could be dangerous and all warrantees will become void. If you experience
a problem, contact our service department or your Wisper retailer.
2.6.2 Wheel spokes should be adjusted after 300 miles of riding. Handlebar and saddle
tubes should never be raised beyond the maximum permissible, indicated by a safety line
around the tubes. The recommended torque (tightness) of crucial fixings is as
follows:
Front axle nuts. 46N.m !
Back axle nuts. 70N.m!
Handlebarandstemclampbolts. 12N.m!
Handlebar stem expander bolt. 10N.m!
Seat pillar clamp nut/bolt. 5-8 N.m!
Seat clamp nuts. 24N.m!
Crank axle Allen bolts. 40N.m!
Gearshifternuts. 4N.m
Other general torque settings depend on the thread size. M4: 2.5-4.0N.m, M5:
4.0-6.0N.m, M6: 6.0-7.5N.m.
10

2.6.3 Your bike has a rear derailleur that will automatically tension your chain. However,
if the chain becomes loose or frequently comes off the front chainwheel, please seek
advice from your Wisper dealer.
2.6.4 Brake levers should lock the wheels when compressed half way between their open
position and touching the handle bars.
2.6.5 Warning: Handlebar hand grips or tube end plugs should be replaced if damaged,
as bare tube ends can cause injury.
2.6.6 Front and rear brake pads must be replaced if the pad material wears to
less than 1mm.
IMPORTANT! braking distances increase on wet or icy roads.
2.6.7 Lubrication:
6.7.1. Lubricate all pivot points on the derailleur and chain with light oil or chain
lube on a regular basis.
6.7.2 Once a year, have your dealer re-grease the headset bearings, front wheel
bearings and pedal bearings.
2.6.8 Recommended tools for proper maintenance:
Torque wrench with lb/in or N/m gradations
2, 4, 5, 6, 8mm Allen wrenches

Whentheon/offbuttonispressedfor3secondstheLCDsymbolswillbecome
visible. When the on/off button is pushed again for 3 seconds, the LCD symbols will
disappear - 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 an unpowered
pushbike.
3.1.4 To lock the battery into the bike frame, hinge into the battery holder in the holder
from the bottom until you hear a click. To unlock the battery, turn the key fully
anticlockwise and hold in this position whilst taking the battery out.
3.1.5 The battery can be charged either on or off the bike.!
3.2. The ON/OFF button and LCD back light
3.2.1 To turn the power on so the pedelec system is operational, simply press the on/off
button (marked with a c-) on the handle bar control for 3 seconds - the LCD
symbols will become visible showing the power is on. When the on/off button is pushed
again for 3 seconds and the LCD symbols become invisible 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 an unpowered pushbike. If the bike is left for ten
minutes without being ridden, the bike will automatically turn off. The battery
capacity indicator lights provide an indication of the battery capacity remaining with
four bars indicating the battery is at full capacity. The display also incorporates a
diagnostic function as described above.
3.2.2 The display back light button is the + button found under the on/off button. If you
press and hold down for 3 seconds when the bike’s power is on, the LCD will
illuminate. Press it again for 3 seconds to switch off the lights.
Important note
Do not press the – (minus) button to turn off the LCD back light as this will
activate the walk along mode and the bike will start to move forward.!
3.3. Torque sensor
3.3.1 When you first ride your Wisper bike, you will notice that the motor will start
working as soon as you put pressure on the pedals. The more pressure you put onto the
pedals the more assistance you will receive.
3.3.2 You will find the assist buttons (marked with a +and a -) on the handle bar
control. Each time the +button is pressed, the LCD will move between 0 and H and the
corresponding power level increases in increments of 25%. Setting H provides 100%
power. The default level is set to 1 when the bike is first turned on. We recommend that
you press, the -button once before you mount the bike so the motor and torque
sensor is deactivated. Once on the bike, press the + button once to activate the
15

assistance mode. You can start off in any level, if you are on a hill for instance you may
want to start in 2,3 or H.
3.3.3 Setting H is generally used when you need the maximum amount of assistance from
the motor, but this will drain the battery the fastest. Lower settings are used when you
do not need the assistance at 100% power. In high traffic situations or poor conditions
such as ice and snow, instant full power could be dangerous. Power settings can be
changed when the bike is stationary or when on the move.
IMPORTANT! Make sure your handlebar grips are always intact and in good condition.
Uncovered handlebar tubes can be very dangerous. !
3.4. Battery capacity meter, riding style and affect on range!
3.4.1 The range of the bike (distance covered between recharging of the battery) is
greatly influenced by the level of assist selected, the amount of pedal assistance
provided by the rider.
3.4.2 If a high level of assist is selected, the range of the bike will be reduced compared
to using a lower level of assist.
3.4.3 The Wisper torque system detects the speed the pedal cranks are turning and the
amount of pressure being exerted on the pedals. This information is fed into an on
board computer (controller) to give the rider the most natural riding experience
possible.
3.4.4 The optimum range is achieved when the rider pedal effort is maximized and an
ideal situation is for the rider to aim to match the power being provided by the bike on
an equal basis.
3.4.5 The battery capacity indicator is provided to give an approximation of battery
capacity remaining. Each bar on the LCD approximates to a ¼of the capacity.
However, this indicator relies on sensing battery voltage that will rise and fall
depending on the amount of power being demanded at any given time, ambient
temperatures etc, hence the meter should only be used for indication purposes.
3.4.6 The battery capacity indicator, built into the top of the battery (four LEDs)
provides a similar indication and operates on the same principle.
3.4.7 Under heavy power situations (high levels of assist) the battery voltage will
temporarily dip resulting in the capacity meter showing a lower level of charge.
When the heavy power is reduced, the capacity meter will rise again as the battery
naturally recovers its voltage.
3.4.8 During the discharge period of the battery, the voltage will drop from an initial
voltage of nearly 42 Volts to a minimum of 31.5 Volts. The bulk of the discharge period
will be in the range of 38 to 36 Volts which provides the optimum performance for the
bicycle. Hence due to this wide range in voltage, the performance of the bike will vary
depending on the state of charge of the battery. To achieve the best possible
performance, it is better to start a journey with a fully charged battery and to recharge
16

it at the end of each journey.!
3.5. Brakes!
3.5.1 Hydraulic disc brakes are fitted to the front and rear wheels of the bicycle.
Hydraulic disc brakes offer several advantages over traditional rim brakes,
including 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.
3.5.2 Details of how to adjust and maintain your brakes are as follows:
3.5.3 Regularly inspect the brake pads for wear. If they have reached the wear limit of
1mm, replace them immediately.
3.5.4 For the front brake, remove the caliper from the fork leg, complete with the
mount adapter by removing the two 6mm Allen caliper fixing screws. For the rear
brake, remove the caliper by removing the two 6mm Allen caliper fixing screws on the
bike frame. The pads can then be removed by unscrewing and removing the pad
retaining screw (which passes through the tabs of the brake pads) using a 3mm Allen
wrench. Then lift the pads complete with the spring out of the rotor slot in the
caliper body.
Warning! Do not loosen any other screws on the caliper.
3.5.5 To refit the pads, hold the pads complete with spring as an assembly and insert
into the caliper slot with the metal backing towards the pistons. Refit the pad
retaining screw ensuring it passes through the holes in the pad tabs and through the
hole in the spring and tighten to 3– 5 N.m. Refit the caliper loosely using the two
Allen screws, apply the brake lever and tighten securely to 6 to 8 N.m whilst
continuing to apply the brake lever. (N.B. use of a thread locking compound is
recommended on the caliper fixing screws).
Warning: If you are unsure about any part of the brake installation process you
should seek advice from a Wisper service center or qualified mechanic. !
!
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 disc should be cleaned with a
proprietary brake cleaning solution.!
3.6. Front suspension forks
3.6.1 Your bike has been fitted with Suntour XCM/SR 29 adjustable hydraulic suspension
forkswithpreloadandhydrauliclockout
17

3.6.2 Adjustment can be made by turning the blue adjuster clockwise when turned fully
clockwisetheforkswillbelockedwithnosuspensionmovement.
3.7. The connectors!
3.7.1 All electronic components have individual connectors, this allows for the easy
removal for diagnosis, repair or replacement of any of the electronic parts. The
connectors, being a push fit are simple to disconnect or reconnect and click into
position when fully engaged. Each connector has a different number of pins and an
alignment arrow, so it is important to ensure the connectors are only mated in their
original positions, as damage may occur to the pins if this procedure is not followed. !
3.8. Quick release saddle height adjustment!
3.8.1 Your Wisper bike has been fitted with a quick release saddle post fitting to
facilitate the movement of the saddle height.
3.8.2 It is important that the knurled nut on the fitting is tightened so the post will not
move in the bike tube. Make this adjustment with the quick release lever in the
open position.
3.8.3 Adjust the seat to the correct height and close the lever firmly. When you sit on
the saddle there should be no vertical movement at all in the saddle post beyond the
seat post suspension movement. Never apply grease to the saddle post.!
3.9. Rims and spokes
3.9.1 It is essential to have your spokes checked and tightened after 300 miles. This is a
free service provided by your supplier. If this service has not been undertaken at the
correct time, this may cause damage to the wheels and spokes that will not be
covered under our Warranty.
3.10. Chain and drive wheel removal!
3.10.1 To completely remove the rear wheel, it is necessary to disconnect the main motor
cable connecting the motor to the bicycle electrical system. This operation is best
achieved by turning the bicycle upside down.
3.10.2 Locate the motor cable where it emerges from the centre of the wheel axle on the
left hand side of the bicycle, slide back the top hat protector to locate wheel nut.
3.10.3 Trace the route of the motor cable along the rear stays and locate the quick
release motor cable connector shown in the image above. Disconnect the two halves of
the connector, taking care not to strain the cables, and unclip the motor cable from
the frame. Note the alignment marks on the two halves of the connector.
3.10.5 Loosen the two large motor axle nuts and remove the nut from the right hand side,
taking care to note the position of any tab washers fitted. Unscrew the left hand nut as
18

far as is possible towards the cable exit from the motor axle, being careful not to
damage the cable.
3.10.6 Lift the wheel from the frame dropouts, being careful not to snag or strain the
motor cable.
3.10.7 Installation is the reverse of the above. Take care to locate the tab washers
correctly in the drop out slots and tighten the axle nuts to the torque specified in
the manual. Reconnect the two halves of the quick release connectors, taking care to
ensure the pins and alignment arrows align correctly. Re-clip the cable to the frame,
ensuring that the cable cannot rub against the tyre and that the cable exits in a
downwards direction from the axle to avoid water ingress into the motor. Refit the
rubber top hat cover.

3.11. Derailleur and gear change!
3.11.1 Full details on how to adjust and maintain your derailleur can be found in the
Shimano manual.
If difficulty is experienced with changing gear after initial operation of the bicycle,
it is likely that some cable stretch will have occurred in the gear change cable. To
compensate for this turn the knurled adjuster shown in the centre left hand side of the
image below by pulling it away from the outer cable stop in the direction of the cable
towards the rear of the bicycle and turning it ½turn anticlockwise when viewed from
the rear. This will compensate for the cable stretch. If necessary, repeat the
operation again until smooth gear selection is obtained or return your bicycle to your
Wisper dealer for further adjustment.
3.11.2 To change gear, use the 9 speed rapid fire gear shifter located on the right side of
the handlebar. The two levers located underneath the shifter can be pulled and
pushed to select the gears over the range 1 to 9.
