Introduction
E-Bikes
Using an electric bicycle is a great way to ride around town conveniently and economically.
E- Bikes represent a natural progression in the development of urban transportaon.
Using only small amounts of electricity, e-bikes have the potenal to radically reduce the
amount of polluon in our cies. They are also very quiet, so they do not add to the high
levels of noise polluon which we oen take for granted. They are easy, and usually free
to park. They are unobtrusive and highly praccal addions to the urban landscape.
E-bikes are also inexpensive. They (currently) require no registraon, no insurance, no
licence and do not incur parking charges. Compared to internal combuson engines, the
engines in electric vehicles have fewer moving parts and require far less maintenance.
Your Daymak e-bike is the result of Daymak’s years of experience, the highly trained
technical skills of our sta, and careful ongoing design work by our engineers. We hope
you enjoy using this product and welcome any feedback that you may have.
New Laws
Most provinces in Canada, most states in the U.S.A, the United Kingdom and many
European countries have new laws that permit cyclists to use electric motors to assist the
regular operaon of bicycles. Please check with your provincial or state government to
learn about your local laws.

Riding Instructions
This guide assumes that you already know how to ride a standard bicycle. Before you try
to ride an electric bicycle, you should be very familiar with controlling and balancing a
normal bicycle.
Cauon
If you do not have cycling experience, an e-bike is too dangerous to ride. Do not begin
learning to ride a bicycle using an e-bike.
Important Notes
• Ebikes are Fast! E-bikes are capable of traveling at higher speeds than many bicycle
riders are accustomed to. Use cauon at all mes, especially when travelling in mixed
trac. Always take into account driving and traveling condions.
• Obey the Law. Be sure to follow all provincial and city trac laws. This includes
obeying stop signs, checking carefully when turning, and riding defensively.
An e-bike is a motorized vehicle, even though it is classed as a bicycle. You must
follow the law.
• Stay Sober. Never ride your bicycle while intoxicated. An e-bike is capable of
traveling faster than a normal bicycle, and you should always be in control of it.
• Share the Road. Be careful in mixed trac. Let vehicles that are faster than you
• Overtake you and give ample room for vehicles travelling slower.

8
Items to Carry with the Electric Bike
It is a good idea to carry the following items with you at all mes when you ride your
e-bike.
• The charger, to charge the bike in case the baery power runs out.
• 30 Amp Fuse, spares for the baeries, in case the fuses blow (if applicable).
• A lock, to secure your e-bike when you park it.
• A helmet, as required by safety laws.
Inspecting your Electric Bike
Always inspect your e-bike before you ride it, to make sure its safety features are
operang properly. Many accidents can be avoided with roune inspecons. Once you
are comfortable with your e-bike, you will be able to detect small changes in the way it
feels. If anything changes between uses, make sure to have it properly examined. Also, be
sure to listen for changes in the sounds your e-bike makes over me. Any mechanical or
power issues may have eects on the sounds the bicycle makes.
Holding the Handlebars
As with a normal bicycle, place your ngers over the brake levers, using the palms of your
hand and your thumbs to wrap around and under the handlegrips. Doing this allows you
to acvate the brakes easily, by squeezing your hand, in case you have to stop quickly. This
is the safe way to control your electric bicycle.
Turning your E-bike On and Off
To turn on your e-bike, insert the key into the “ignion”, located just below the dash
board, and turn the key to the right. When your e-bike is acvated, the power indicator
will light and the baery charge indicator will jump, showing you how much power your
e-bike has. To turn o the e-bike, simply turn the key to the le, and remove the key.

9
Warning
When you acvate the e-bike, the electrical system becomes live. Do not try to aect
changes to the E-Bike (such as removing the baery or repairing electrical components)
while the E-Bike is acvated. Turn the E-Bike o and remove the key before you aempt
to access any of the electrical components. Also, the baery carries a signicant electric
charge and can injure people if not treated properly and with respect.
Accelerating and Decelerating
The throle is found on the right-side hand grip on the handlebars. Turn rotate the grip
counterclockwise (towards from you) to accelerate. To decelerate, release the grip (turn
it away from you). Don’t over-rotate the accelerator, as this could damage the baery and
electrical components.
Warning
Do not acvate the accelerator unl you are seated on the bicycle and are ready to
accelerate. The e-bike can easily escape from your control, possibly injuring you or others,
and the e-bike may be damaged by being dropped.
Stopping
Your e-bike has two sets of brakes, at the front and at the rear. The levers aached to
the handlebars, on the le and right, acvate the brakes. Pull the levers toward you to
acvate the brakes.
You can use both brakes to come to a stop more quickly, or you can use one of the brakes
to come to a gentle stop, depending on your riding needs at the moment. When the
brakes are acvated, the power to the engine is automacally turned o, unl you release
the brakes. This allows you to stop safely.
Safety Tips
• When you are traveling in wet weather, water may cause your brakes to funcon
less eciently because it reduces fricon between the brake pads and the wheels.
• Take care to slow down and give yourself more room to stop or slow if necessary.
• It is a good idea to have your brakes and brake pads checked regularly. The brake
pads will eventually wear down through fricon, and aer signicant use will have to
be replaced.
• Engage the rear brakes rst before the front brakes to avoid ipping the unit.

10
Signalling
The Horn
The e-bike has a horn. The horn buon is on the le handlebar. Simply press it to acvate
the horn.
Turning Signal Lights
Your e-bike has turn signal lights. The turn signal acvator is on the le handlebar. Push
it le or right to acvate it to indicate that you are turning in the appropriate direcon.
Lights
The headlight and tail light are useful features when you are riding at night or in dark areas.
They radically improve your safety in mixed trac. The lights on your e-bike consume
some electricity. Keeping them on may reduce the maximum distance you can travel on
one charge by about 5 %.
Pedaling
This e-bike is designed to be a motor-assisted bicycle. You can use the motor by itself,
but ideally, you can work with the motor by pedaling. This increases the distance you can
travel on your e-bike, because it assists the motor and reduces the amount of electricity
you draw from the baery.
Riding in Wet Weather
Your e-bike is designed to funcon in wet condions, such as when it is raining. However,
because the motor is on the rear wheel, it is easy to slip when moving at high speeds. If
it is very wet, be sure to avoid high speeds. When you are traveling in wet weather, water
may cause your brakes to funcon less eecvely because it reduces fricon between the
brake pads and the wheels. Take care to slow down and give yourself more room to stop
or slow if necessary.
The Motor and Water
Your e-bike is not designed to be immersed in water. Always ensure that the water level
does not go above the middle of the re, to prevent water from geng inside the motor.
Water in the motor can cause short-circuits and may damage the electrical systems in
your e-bike.

11
Riding in Cold Weather
Your e-bike is designed to operate year-round. However, in very cold condions or when
there is a lot of snow or slush on the ground, it is possible for the motor in the e-bike
to get wet or for the brakes to funcon less eecvely, just as it can happen in wet
weather. Below 10 degrees Celsius, the baery will not work as well as it would in warmer
temperatures. While Lithium-Ion baeries perform beer than Lead-Acid baeries in
temperature extremes, both will experience reduced performance in cold temperatures.
Also, riding the e-bike in cold temperatures may require you to replace the baery sooner
rather than later.
Maximum Load
Do not exceed the maximum load capabilies of your e-bike. You can nd the exact loading
capacity listed in the technical specicaons in this guide.
If you exceed the maximum load, the performance of the bike will suer.
Exceeding the maximum load of your e-bike could cause damage to the shocks, to the
mechanism and, ulmately, even to the frame. It could also cause your motor to work too
aggressively, and may cause it to burn out.
Disconnecting the Circuit Breaker
When the circuit breaker is disconnected, all power from the baery to the e-bike is
blocked. This is useful if you are going to store your e-bike or if it is damaged and you wish
to bring it to be serviced.
Note: The circuit breaker must be on for the alarm system to work. Do not leave the
circuit breaker o in an unsafe locaon if you are worried about the.
Long-Term Storage of your E-bike
If you are storing your bike for a long period, disconnect the circuit breaker. This is a safer
way to store the electric bicycle, as it prevents accidental acvaon of the e-bike and
makes it impossible to acvate it even with the key.
Please see the secon tled “The Baery” for instrucons on baery maintenance while
your e-bike is being stored.

12
The Battery
This secon details what you need to know about the baery that powers your e-bike.
Always remember to treat your e-bike’s electrical systems with respect.
Battery Power
The dashboard has a baery charge indicator. When the e-bike is acvated, the guage
will jump and indicate the currently available baery power. If the power has dropped
signicantly, you should charge your e-bike.
Distance and Power
Your baery has the capacity to carry you anywhere from 35+ km before it must be
recharged. The ability of your baery to power your bicycle depends on many variables.
These variables include the weight of the rider, the prevailing wind resistance, the rider’s
driving habits, the presence of steep hills and inclines, and other issues such as proper air
pressure in the res.
Saving Power
If you are traveling long distances, you can save a lot of electricity by using beer driving
habits:
• Coasng: When going downhill or over long, at road surfaces, try using your e-
bike’s momentum and allow it to coast, without drawing power from the motor.
• Stopping and Starng: Try to avoid stop and go movements. The motor draws
more power when starng from a full stop.
• Weight: Remove unnecessary weight from the bike. This reduces the amount of
power the motor must draw.
• Air Pressure: Make sure your res have the proper air pressure. Proper pressure
reduces drag on the res and radically increases the eciency of any vehicle.
• Head and Tail Lights: Turn o the lights to conserve power, if it is safe to do so.
The lights will reduce the distance you can travel by about 5%.
• Pedalling: When accelerang from a full stop, you might want to try pedaling to
help acceleraon.

13
Charging your E-Bike
Charging your e-bike is a simple process. You require the following:
• The charger that came with your e-bike.
• A 110V household electrical outlet.
Charger Warning
Only use the chargers that were supplied with your e-bike. Using chargers that do not have
specicaons idencal to those which came with the e-bike could irreparably damage
your e-bike’s baery and electrical systems, and may cause injury.
To charge your e-bike, follow these steps:
1. Turn o the e-bike and remove the key from the “ignion.”
2. Plug the female end of the charger cable into the charging slot on the e-bike.
3. Plug the male end of the charger power cable into your wall socket. This should be
a110v household electricity supply. You can also use a portable generator, if necessary,
but make sure it provides 110V current.
4. Allow the e-bike’s baery to charge for the appropriate amount of me
(6-12 hours).
5. Disconnect the charger when the LED light on the charger is green. The baeries
have been fully charged.
If your charger’s LED status light does not change from red to green over an extended
period of me, for perhaps more than 14 hours, and the baery is very hot, the baery
or charger may need replacing. Stop charging and bring both to your Daymak dealer
immediately. Do not charge the baery.

14
Understanding your voltage
Electric scooters primary power is displayed on your unit as a voltage. This number in
short shows how powerful your unit is, and as it dips down when the unit will no longer
be able to perform. Depending on your unit’s voltage and baery type (Lithium vs Lead
Acid) will eect the range of voltage between what is fully charged and when it exceeds
the low voltage threshold.
Low Voltage Threshold
Your unit will try to protect the baery by prevenng the motor from drawing power below
the Low Voltage Threshold. By doing this it will signicantly increase the life expectancy of
your unit. If you nd that your motor starts cung o at a certain speed or not engaging
at all it may be because your voltage is dropping past the threshold point and needs to be
charged. To see what your voltage threshold you can check on it via the bluetooth APP (if
applicable) and you can check it out using this chart.
Voltage Chart
LITHIUM Full/Low Voltage Reading
Depending on the way your lithium baery’s composion will impact what the low
voltage and full charge reading should be. Underneath each reading on the above chart
shows a number and a “S” this represents how many series are in your baery pack. To
know the exact series of your baery contact your local Daymak dealer.

15
Charging the Em4 (direct)
The EM4 comes with two lithium Ion ba ery packs that can be charged together or
individually. These can be done both in and out of the bike. To charge the EM4 directly in
the unit look for the charge port underneath the seat. It will be covered with a  ap that
you must li up and then plug the female end into that port.
Once the bike is charging the charger will glow red. When the unit is fully charged the
charger will glow green and then your bike is ready to go.
Warning
Do not leave the EM4 charging for long periods of  me a er it is fully charged. Once the
bike is charged unplug it ASAP.
Accessing your Circuit Breaker
To prevent surges, we have installed a circuit breaker.
If you are unable to get power to your bike more
than likely your circuit breaker has been triggered
and needs to be switched to the on posi on.
To do this:
Unlock the glove compartment, and li up the
holding container. (See next page for more info)

16
Charging the Em4 (Out of unit)
With the EM4, you can remove the ba eries and charge them outside of the unit. You can
operate the unit with only one ba ery inside the bike allowing you to charge and ride at
the same  me. This can be done by doing the following:
Locate the keyhole on the le side of the bike just
under the seat of the unit. Put the key in here and
then turn it to unlock the glove compartment.
Locate the keyhole on the le side of the bike just
under the seat of the unit. Put the key in here and
then turn it to unlock the glove compartment.
Once the glove compartment is unlocked and li ed
up, you can li this sec on up as well to reveal
both lithium ba eries and the circuit breaker.
Battery Compartment
1. Circuit Breaker - Use this to stop all power to the unit.
2. Charge port - Use this charge port to charge each ba ery individually.
3. Anderson Connector - These are used to connect the ba eries to the bike.
One must be plugged in for the bike to work.
4. Handle - Li the ba ery from here to take it out / put in the bike.

17
Charging the EM4 (Out of Unit) continuted
Once the ba eries are out of the unit you can charge them directly in the charging
ports that are on the ba ery. This will allow you to charge one ba ery while the other is
powering your bike. You can see the charge port on the pictures below.
Note: If you buy an addi onal charger, you can
charge the EM4 outside of the unit in half the  me!

18
Battery Care
Follow these suggesons to maintain your baery’s opmal performance. If you do not
follow these suggesons, your baery may lose its ability to maintain a charge and might
have to be replaced sooner than would otherwise be necessary.
• Charge it: Charge your baery immediately aer riding it.
• Full Charge: Do not allow the baery to run down completely and lie in storage
without a charge. This signicantly reduces the baery’s lifespan and may cause
damage.
• Keep it Charged: When being stored, charge the baery occasionally to make
sure its power supply does not run down. Charging it once every 21 days should be
sucient.
• Storage Condions: Store the baery on a at, cool, dry surface. Do not allow the
baery temperature to drop below 10 degrees Celsius for extended periods of me.
Warning
DO NOT place your Lead-Acid baery on concrete. Concrete drains the baery’s power
and will neutralize the lead-acid. Placing the baery on concrete for any length of me
will likely result in the baery being drained of power and possibly losing its ability to
store electricity.
Cold Weather and your Battery
Below 10 degrees Celsius, the baery will not work as well as it would in warmer
temperatures. While Lithium-Ion baeries perform beer than Lead-Acid baeries in
temperature extremes, both will experience reduced performance in cold temperatures.
Also, repeatedly riding the e-bike in cold temperatures may cause your baery to have to
be replaced sooner.
Replacement and Disposal
Aer approximately 300 charges, a lead-acid baery will need to be replaced. A lithium-
ion baery will last approximately 1000 charges. When the baery has to be replaced,
you will noce that your baery cannot carry as much of a charge as it could inially.
Contact your local Daymak dealer to purchase a new baery.
When replacing your baery, dispose of it at a proper municipal baery recycling facility.
If none is available, please contact your local Daymak dealer.
