First bike ride on the Cortes
Safe on the road
In addition to your skill on the Cortes, which will improve as you use it, it is
important that your bike is in optimum condition when you hit the road. We
recommend that you take the following aspects into account:
•Before each use, check the condition and function of the brakes, tyres,
rims and steering system.
•Bear in mind that the braking characteristics change and the braking
distance may increase if the road surface is slippery.
•Make sure that any luggage is securely fastened and cannot move.
•Ride on flat and firm surfaces and avoid deep potholes, high thresholds,
puddles of water and inclines greater than 10%.
•Ride at an appropriate speed on wet or slippery surfaces, slopes or
precipices. Avoid bumping into kerbs.
Always lock your bicycle when parking it (with a cable lock if desired).
Use the parking brake to avoid the possibility of driving off.
•he Cortes is largely made of steel, which is considered non-flammable.
The other materials used, such as plastic, rubber, etc. are not fireproof.
•When starting off on a steep slope, lean forward if necessary to prevent
the front wheel from lifting. If you are riding backwards on a slope, brake
carefully until you come to a stop.
ADVICE FROM RICHARD Make sure that the handlebars and saddle are
properly adjusted before you start cycling. This way, you can assume the
correct posture on the bike.
The time has come. Your first experience on your own Cortes! Whatever bike ride
you do, your safety comes first! If it is your first time cycling on a Huka tricycle, you
might have to get used to it. The most important tip we can give you is that you
have to relax as much as possible while cycling. To make sure everything goes as
smooth as possible, we give you some instructions.

11
•When you get on, lift your foot to the other side so that your feet are on
either side of the bike. Take a seat on the seat system.
•Stay seated upright at all times and keep your feet on the pedals. Even
when you brake or stand still.
•Descend a slope at a moderate speed so that you can always come to a
stop in time and in a safe manner.
•Wear an appropriate bicycle helmet.
•Wear reflective clothing to increase your visibility on the road.
ADVICE FROM RICHARD When cycling, steer with your arms and not
with your body. Cycling into corners takes some getting used to. In order
to maintain stability, lean your body slightly towards the inside of the
bend. Avoid sudden and violent steering movements. In this way you
can avoid accidents and damage.
Parking brake activation
Boarding and cycling
Always use the parking brake when getting on or off the
bike safely so that the bike remains stationary. Apply the
parking brake by squeezing the right brake lever (of the
rear wheels) and then press the locking pawl. If the hand
brake is now released, the parking brake is on.
To release the bike from the parking brake release the
parking brake, briefly squeeze the brake lever. Put it in

first gear (if important) so you can pedal more lightly. As soon as you are seated
and want to ride, remove the bike from the parking brake.
www.huka.nl/en

12
Cycling with pedal assistance
Your Cortes is equipped with pedal assistance. The electric motor is activated as
soon as you start pedalling. Pedalling then becomes lighter. When you stop
pedalling, the pedalling assistance stops as well.
•The pedal assistance is switched on by pressing the on and off button on the
display for a few seconds. This also switches the pedal assistance off.
•The support can be set at different levels using the buttons on the handlebar.
•By pressing the 'mode' button, you can scroll through the menu on the display.
The distance ridden, range, riding time and speed are shown.
Brakes
The Cortes is equipped with hand brakes. Braking is done by squeezing both
brake levers on the handlebars. The left hand brake operates the front wheel
brake. The right hand brake operates the brakes of both rear wheels. When
cornering, it is best to use the right-hand brake. Practise braking on a large
enclosed area before you hit the road. You will then become familiar with the
system.
Be careful with the front brake when cornering. Using only the front
brake in a corner can cause instability of the bike. This can lead to
personal injury and/or property damage.
Always use the parking brake when getting on or off the bike. This
prevents the bicycle from rolling away. This reduces the risk of falling.
ADVICE FROM RICHARD When changing gears, make sure you stop
pedalling and select the desired gear. Do not continue pedalling when
changing gears. This can damage the gear-shifting mechanism. Damage
to the gear hub as a result of abuse is not covered by the warranty.

Battery display Shimano StepS
Exposure to bright sunlight can make various materials very hot.
The product contains moving parts. These include the steering wheel,
wheels, etc. Be alert to the danger of crushing.
Vigilance is recommended when using electrical equipment such as a
mobile phone when the electric drive is on
Moving and carrying the bicycle
To move or carry the bike, you can grab it by the frame tube at the back and by the
head tube at the front. We recommend that at least two people should be used to
lift the bike. When lifting, also hold the handlebars to prevent the front wheel and
handlebars from turning and possibly causing injury.
The detailed explanation of the pedal assistance can be found in the manual of
the manufacturer of this assistance. First check which brand of pedal assistance
is fitted.
Battery indication
The display shows how full the battery is. Check that the battery is full when
you travel (longer) distances. The white block gets shorter as the battery gets
emptier. When the white block is completely white, the battery is full. There is
also a battery indicator on the battery itself.

Product description
Your Cortes consists of several parts. The most important parts are described in
this chapter.
Bicycle frame
The frame of the Cortes consists of a tubular metal construction complemented by
aluminium and stainless steel components. Most of the metal parts are phosphated
and then provided with an impact-resistant powder coating. This construction and
finish guarantee years of cycling pleasure.
Drive
The tricycle has its own specially designed drive system on the rear wheels. This
drive (by means of a differential) ensures that the bicycle does not twist and that
bends can be taken easily. The
bicycle without
differential
Huka bicycle with
differential
differential means that both
wheels are driven independently of
each other. The bike goes straight
ahead and turns more easily.
Wheels and tires
The wheels are equipped with quality hubs, stainless steel spokes and an
aluminium rim. A-quality tyres are mounted on these rims. These provide good
grip, low rolling resistance and less wear.
ADVICE FROM RICHARD Regularly check tyre pressure and tyre
wear to ensure safe cycling. Tyre pressure and tyre wear has a major
influence on how your bicycle behaves.

15
Spokes
A correct tension of the spokes ensures a stable tricycle. Because of the
functioning of the new spokes, the wheels of your Cortes need to be checked after
200 kilometres or 2 months. Your Huka dealer can take care of that. Should a
spoke break or become loose, consult your Huka dealer as well.
Chainglider & chain
The chainglider is made of impact-resistant plastic. This chainglider protects the
chain from dirt and water and also ensures that the chain cannot soil your legs or
clothing.
With a good chain tension your Cortes will pedal lightly and you won't hear the
chain. If you notice that the chain is too slack, have it adjusted by your Huka
dealer.
Brakes
The basic model of the Cortes is equipped with a V-brake as a front brake. Next to
that the hydraulic disc brakes control the rear wheels. Your Huka is also provided
with a parking brake that you use when getting on and off the bike.
TIP
ADVICE FROM RICHARD In time, brakes can wear out and are very
important for safety while cycling. That is why you should have your
brakes checked regularly and, if necessary, adjusted or replaced. Your
Huka dealer can help you with this.
Always ensure that the parking brake is activated when getting
on or off the bike. This prevents the bike from rolling away.
www.huka.nl/en

16
Bottom bracket, crankset and pedals
•The bottom bracket bearings that Huka uses are completely maintenance-free
and cannot be adjusted. If the bearing does get loose, go to your Huka dealer
immediately. If there is play between the crank and the bottom bracket, take
off the dust cap and tighten the underlying bolt with a socket spanner 14.
•Most pedals are maintenance-free. Is there too much play? Then consult your
Huka dealer. When assembling the pedals yourself, pay attention to the
indications L (left) and R (right) on the pedal axles. You turn the left pedal
counter-clockwise. You tighten the right pedal clockwise. To do this, use a 15
mm spanner or a special (narrow) pedal spanner.
•Various (modified) pedals are available as an option.
Gears
Your Cortes is equipped with gears, with the gear hub sitting between the pedals
and the drive shaft. This is an 8-speed hub by Shimano type Nexus that is geared
to the Cortes. Upon delivery, your Huka dealer checked the gears and adjusted
them correctly. The explanation of the gear hub can be found in the Shimano
manual.
The seat system and handlebars must always be tightened securely.
Check this regularly. A loose seating system and/or handlebar can
create an unsafe situation.
Handlebar
The handlebars of the bicycle can be made of steel or aluminium. This depends on
the model of bike or handlebar chosen. The handlebar is always adjustable in
height. With some handlebar models, the angle and depth are also adjustable.
Adjusting the gear hub is highly specialized work. This should only be
done by a Huka dealer.

17
Luggage adapter
Optionally, the bike can be fitted with a specially designed accessory adapter
where various luggage systems can easily be mounted. Ask your Huka dealer
about this, so the right materials can be used and the whole thing can be mounted
safely.
Lighting
The Cortes is equipped with lighting that is connected to the battery. Therefore, the
Cortes is not equipped with batteries.
Seat system
The seating system provides comfort and stability while cycling and is adjustable
in depth and angle. It is very important to adjust the seating system correctly in
order to cycle efficiently, comfortably and safely. A swivel seating system is
optional and will make getting on and off the bike easier.
ADVICE FROM RICHARD Check regularly that the seating system is
screwed in tightly. A loose seating system can create unsafe situations.
If you use the accessory adapter, distribute the load as well as possible.
The maximum load is 25 kg.
Alterations to the accessory adapter affect its safety and are not
permitted. The accessory adapter is not suitable for a trailer or bicycle
seat.
If the accessory adapter is loaded, this may affect the riding and braking
characteristics of the bike. Always make sure that lamps and reflectors
remain visible.
www.huka.nl/en

18
The luggage must be properly secured and distributed. Incorrectly
secured luggage can be dangerous for the participating traffic. Straps or
belts must be properly secured to prevent them from getting into the
wheel.
Electric pedal assistance
The Cortes is equipped with electric pedal assistance. The bike is equipped
with a mid-motor which is mounted to the frame in a specially designed
adaption. The battery pack and electronics box are mounted to the rear
frame. There is also a clear display with controls mounted on the
handlebar.

Optimal use
Upon delivery of your new Huka, the parts have been adjusted to your body and
to your wishes. To make sure you are comfortable, there are adjustment
possibilities for the seat system and handlebars.
Setting the seat depth
1. Remove the protective caps.
2. Loosen the 3 M8 bolts on both sides of the bike
slightly using an Allen key.
3. Place the seat in the correct position.
4. Tighten the 3 bolts on both sides of the bike.
ADVICE FROM RICHARD A good rule of thumb for the adjustment of
the seat is to sit on the bike without shoes with the crank in line with the
seat frame. With your heel on the pedal, you should barely be able to
extend your leg. From this position, you can adjust the depth of the seat
to the most comfortable position for you.
The height of the seat changes automatically when the seat depth is adjusted,
because the mounting tube runs diagonally upwards. When the seat depth is
adjusted correctly, the seat height will automatically be right. With the seat in
the right position, you will effortlessly pedal away the kilometres.
1. Using an Allen wrench and a size 13 socket wrench,
disassemble the 2 bolts.
2. Tilt the seat to the correct position in terms of its setting
and secure it again with the bolts on the adjustment
strips with the fixing holes.
3. Refit the bolts and tighten firmly.
Setting the seat angle & height
The seat angle is individually adjustable and partly influences
the creation of a good sitting position.
