Electric Bike
The electric bike of Darad Innovation is an electrically assisted bike that provides assistance when
you are pedaling. The rpm sensor located on the pedal crank bearing detects how hard you are
pedaling the bike and determines how much power the motor should provide to give you a ride. The
electric motor is turned off as soon as you stop pedaling. At the maximum aided speed, the motor
starts to reduce its power output until the aided pedals are turned off. For example, the maximum
aided speed is 25km/hr (15.5mph) in European countries. You may ride faster than this maximum
aided speed if you turn off the assisted pedaling function.

Pre-riding Check Check
the Tires and Wheels
While riding an electric bike, the tire valve may break if you sit one-sidedly on the bike. If this
happens, the tire will lose pressure and there is a risk of accident. Therefore, always check that the
valve is at the correct location. It has to extend from the edge of tire inclining towards the right hand
side. Correct the valve immediately if the position is off. Check the following every time before you
mount your bike:
•
Check that the tires and wheels are intact without damage and whether the tires are pierced by
any foreign object. Damaged tire will lose pressure and further damage.
•
The depth of tire treads.
•
Normal activation refers to the two wheels rotating freely. If a wheel is not rotating in a perfect
circle, it is possible that the tire broken, has a damaged axle orworn spoke.
In addition, investigate the source of any unusual noise if necessary, and check the loads carried
and the tightened connection.
Check the Chain and Chain Cover
While riding an electric bike, the chain and cover that are not tightened may be slacking and cause
accident and injury. Make sure that the chain is engaged and tightened and that the cover is
secured every time before riding the bike. Check also that the chain and chain cover are installed
correctly to prevent falling off or sliding.

Check the Operation of Brake System
Test the brakes before riding the bike every time. Check
the brake lever with 2 fingers. Pull the lever to make sure
the amount of force is adequate. The brake levers should
not touch the handle bar. The brake levers should always
keep a proper distance with the handle even with the
largest force your hands can provide.
Check braking system wearing
The brake discs, motor, couplings that spin rapidly and the nuts of axle become very hot after
frequent braking particularly on a descending road for an extended period of time, and there is a risk
of injury. Do not touch them until they are cooled off. Check that the brake shoes are installed and
test the brakes every time before you ride the bike:
•
A good disc has to be free of any wearing, grease and dirt.
•
All bolts shall be fastened at the current positions.
•
Make sure that brake cables are not entangled and check the cables for signs of cracking.

Notes for rear luggage carrier (optional)
A loaded luggage carrier will alter the characteristics of riding the bike. The ability of riding or
braking will be weakened, and the braking distance, as well as the risk of accident, will increase.
•
Keep the center of gravity of your load as low as possible. Riding a bike with lower center of
gravity of a heavier load is faster than with a lighted load.
•
Bend you body when making a turn and be careful while doing it.
•
Consider a longer braking distance.
•
Keep in mind the added weight when stopping or parking the bike.
Poorly placed load may fall off the carrier, and worse, the falling object may get caught by the rear
wheel or chain, causing serious accident and injury.
•
Transport loads only using an electric bike with a luggage carrier or wire net.
•
Always secure the object you are about to carry, or the object may fall off causing accident and
injury.
•
Always check before every trip that the rear luggage carrier is securely fastened, or the carrier
may separate from the bike and fall off, causing risk of accident and injury.
•
Check that the screws holding the luggage carrier are secured before every trip.
•
Do not modify the luggage carrier and its fixing points.
If the luggage carrier is overloaded, the cargo may fall off the bike, causing the risk of accident

Riding Manual Electric Power
Levels for Electrically Assisted Riding
In case of slippery pedals or riding on a slippery surface, the rear wheel may skid and lose traction
when you accelerate, and there is a risk of accident. Please turn the pedaling assistance off when
on a smooth or slippery surface. The Darad Innovation electrically assisted bike is designed to
provide assistance when you pedal hard. The motor is turned off when you stop pedaling.
The pedaling assistance is turned off if you exceed the maximum aided speed (depending on
countries). The assistance power depends on the level of assistance you select. The higher the
level you select, the less force you have to apply to maintain a specific speed. By pushing the left
pedal, the rpm sensor will receive the pedaling force more effectively and the power controller
system is activated more quickly for your aid. This gives you an advantage when riding on an up
slope.

Brake System
The Darad Innovation Electrically Assisted Bikes are all equipped with mechanical disc brake of the
same level. It brings you quick and safe stop if necessary. The disc brake reacts much quicker than
drum brake particularly on slippery roads. The mechanical disc brake gives you very good braking
results with only very little force from your hands. To evenly distribute the braking force in both
wheels, please brake both wheels at the same time. The following are some notes for braking the
bike:
•
On a slippery road, the friction is reduced between the surface and tires. The water reduces the
braking effects of the brake shoes and disc. As a result, the braking distance will be longer and
there is a risk of accident.
•
When riding ona wet surface, brake early to keep a longer braking distance. Beextra careful not
to allow the brake to lock the wheels up.
•
The rear wheel may be airborne when you hit the front brake too hard, and there is a risk of
accident.
•
Always slow down or stop the bike with both the front and rear brakes. Carefully maintain your
balance during a sudden brake.
The motor-assisted pedals are brake-controlled (or if you stop pedaling) for interruption. If you are
not yet familiar with the braking power of the mechanical disc brake, please do so on a surface with
good traction and away from traffic. Avoid braking consecutively. When on a long down slope, use
both brakes in a steady burst of short braking actions. The brakes will cool down when you apply
them intermittently. Stop the bike at any sign of overheating. The symptoms of overheating include
extra braking force required, a concentration of burning smell and loud noises.
Allow the braking system to cool down before riding. A wet condition reduces the braking effect and
easily causes the tires to skid.
Always keep a longer braking distance on a wet road surface. Ride slowly and brake carefully.
Wearing of Brake System
The wearing of brake shoes and discs is the result of friction. The more you ride the bike in a
mountainous terrain or in rain or mud, the more worn the bike will be. The wearing of brake shoes
and discs cannot be evaluated from the brake rods alone. Therefore, it is necessary to check before
riding. Always go to a qualified distributor for replacement of brake shoes.
Replacement of new brake pads
New brake shoes must be inserted when they reach their best braking performance. To do that, you
need to accelerate the bike up to 25km/hr (15.5mph) and apply the brakes. The replacement is
done when the force you apply to the brakes stop reducing.

Batter y Protection Mode
For any of the following, the battery will switch to the protection mode:
•
The bike has not be used for two months.
•

When the battery is in the protection mode, you need to start the battery after a complete charging
cycle.
Notes for Battery
The following instructions helps improve the longevity of battery:
•
Ideally, the battery should becharged at20°C (68°F). Please allow plenty of time for the battery
to reach this temperature before charging.
•
Avoid frequent discharging completely. It is preferred to discharge locally. Li batteries are not
known for the memory effect. Loss of capacity after a period of use is common in every Li
battery. The oxidation of cores occurs as the result of long period of use and aging, and leads to
loss ofcapacity.
•
Deep discharging of a battery will lead toirreversible damage and loss of capacity. If the battery
is expected not to be used for an extended period of time, it is advised to charge the battery to
its full capacity at least every 3 months.
