1Introduction
Thank you for choosing Ratikon electric bicycle.
Before you use your Ratikon electric 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 do not lend your bicycle to anyone who is unfamiliar with it.
We strongly advise you to always wear an approved cycling 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,
handlebars 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 or one of our distributors and we will make sure it is properly recycled.
Above all, enjoy your Ratikon bike, happy cycling!

3Controls and equipment
In this section, the functions and any specific maintenance needed on all the main controls and
ancillary equipment are described.
3.1 Battery on/off switch and lock
3.1.1 Your Ratikon bike is supplied with two identical keys. The keylocks the battery to the bike.

11
3.1.2 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, Press down the button
directly above the frame to turn on the power, press the button again to turn off the power
Fig 2
3.1.3 When the battery has been turned on, the bike is now ready for use. The on/off button on
isolates the power from the bike.
When the on/off button is pressed for 1 second the LCD symbols will become visible. When
the on/off button is pushed again for 1 second, 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, slide the battery into the battery holder in the rack
until you hear a click. To unlock the battery, turn the key fully anticlockwise and hold in this
position whilst siding the battery out.
3.1.5 The battery can be charged either on or off the bike.
3.2 The ON/OFF button and Light button
3.2.1 To turn the power on so the pedelec system is operational, simply press the ON/OFF button
on the handle bar control for 1 second - the LCD symbols will become visible showing the power is
on. When the on/off button is pushed again for 1 second 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.
3.2.2 To switch on bike light, hold the UP button for 1s. The lighting icon comes out and display
backlight brightness is automatically reduced.

12
Likewise, hold the UP button for 1s again, the bike light switches off. The lighting icon is gone and
display resumes backlight brightness.
The power for the lights comes from the bike battery, but due to the low power consumption of the
LED lights, you will not noticeably reduce your range.
3.3 Pedal assist power
3.3.1 When you first ride your Ratikon bike, you will notice that the motor will start working when
you have turned the pedals through between 90 and 180 degrees.
3.3.2 You will find the assist buttons (marked with + and -) on the handlebar control. Each time the
UP button is pressed, the LCD will move between 1 and 5levels and the corresponding power
level increases in increments of 25%. Setting 5provides 100% power. The default level is set to
1 when the bike is first turned on. We recommend that you only turn on the bike after you
have mounted the bike so the motor is deactivated. Once on the bike, press the on button for
one second and the assistance will be turned on. You can start off in any level, if you are on a
hill for instance you may want to start in level 2,3,4 or even 5.
3.3.3 Setting 5 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 and the use of the throttle.
3.4.2 If a high level of assist is selected, then the range of the bike will be reduced compared to
using a lower level of assist.
3.4.3 The cadence sensor system detects the speed the pedal cranks are turning and the 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.

13
3.4.5 The battery capacity indicator is provided to give an approximation of battery capacity
remaining. 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 provides a similar
indication and operates on the same principle.
3.4.7 Under heavy power situations (full throttle or 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 usage 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 it at the end of each journey.
3.4.9 Be aware that recommended temperature range of use of the bike with battery is -10 ~ 40
°C.
3.5 Brakes
3.5.1 Disc brakes are fitted to the front and rear wheels of the bicycle. The braking direction is left
for front and right for rear. Disc brakes offer several advantages over traditional rim brakes,
including better braking in wet, muddy or other adverse conditions and less braking power
fade over extended downhill braking.
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 the front brake pads have reached the wear
limit of 1mm, replace them immediately. The rear brake blocks should be checked by a
bicycle mechanic and replaced when necessary.
3.5.4 Front brake, remove the caliper from the fork leg, complete with the mount adapter by
removing the two 6mm Allen caliper fixing screws. 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.
3.5.5 After braking during riding, do not touch the disc brake disc with your hands immediately to
avoid burns.
Warning! Do not loosen any other screws on the caliper.

14
3.5.6 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 8N.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 Ratikon 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 The connectors
3.8.1 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, damage may occur to the
pins if this procedure is not followed.
3.7 Quick release saddle height adjustment
3.9.1 Your Ratikon bike has been fitted with a quick release saddle post fitting to facilitate the
movement of the saddle height.
3.9.2 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.
3.89.3 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. Always check the minimum
insert mark on the seat tube to avoid injuries and frame damage.

15
3.8 Rims and spokes
3.10.1 It is essential to have your spokes checked and tightened after 400km. 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.
3.10.2 Check the rims before riding. You need to confirm whether the rim or steel wire is damaged
and whether the hub rotates smoothly. Once you find damage or poor rotation, you need to
find the cause in time and use it after maintenance.
3.10.3 Rim Care and Rim danger: It is strictly forbidden to lubricate the front and rear brakes and
the tires during maintenance of the rim; regularly check the tire wear and tear, and if it is
found that the tread wear is serious, the tire needs to be replaced in time.
3.9 Derailleur and gear change
3.12.1 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 ½ turn 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 Ratikon dealer for further adjustment.
3.12.2 To change gear, use the 8 speed gear shifter located on the right side of the handlebar.
4Warranty, battery maintenance and user responsibilities
Repair or replacement of components
Only use this product in accordance with this user manual. Ratikon offer a limited warranty on the
bicycle.
Exceptions to Limited Warranties
Your Ratikon bike may not be covered by our warranty for any of the following reasons:

16
1.
Damage resulting from misuse, not maintaining the bicycle or not following the guidelines
within our user guide or using the bicycle for any kind of competitive sport.
2.
Accidental or deliberate damage.
3.
Damage due to private repair or alteration by user or unauthorised service centre.
4.
Failure to produce invoice or proof of purchase.
5.
Spare parts and components worn in normal use.
6.
Failure to have your bike safety checked and the spokes tightened within 400km or three
months of purchase.
4.1 Battery maintenance and user responsibilities
4.1.1 Your Ratikon bike is equipped with a powerful, high quality lithium ion battery. Lithium ion is
recognized as being the very best type of battery for electric bicycle use.
4.1.2 All lithium ion batteries must be well cared for to optimize useful life and range. It is the
responsibility of the bike owner/operator to ensure the battery is looked after properly.
Incorrect use or storage of your battery may cause damage and void your warranty.
4.1.3 It is not unusual for a well-maintained battery to last for several years. Though your bike will
feel less powerful as the battery gets older, and the range will diminish, you can continue
using the battery for many years to come.
A key point to remember when choosing a battery is to check the battery capacity (V x Ah =
Wh the battery’s capacity) i.e.16Ah x 36V = 576Wh. When such a battery loses 30% of its
capacity, it will still have nearly 400Wh left, still more than a new 36V 10Ah (378Wh)
battery. Choosing a larger battery not only gives you more power and range but is often
more economical in the long term.
4.1.4 The key to having a long lasting battery is to look after it. This means never leaving your
battery fully discharged and always conditioning the battery when not in use i.e. in the
winter.
4.1.5 If a battery is not cared for as per our instructions, it will not reach its optimum performance
and may not be covered by our warranty.

17
We reserve the right to check batteries claimed under warranty to ensure they have been
maintained as per our instructions.
