Introduction
Read all information in this manual carefully before using the Quattrocycle.
The Quattrocycle is an innovation in the area of 4-wheel bikes. It combines the joy of
cycling together on a bike with the comfort level that is also delivered in normal
modern bikes:
Everyone has a freewheel, so you don’t have to pedal all the time.
Each rider can choose its own gear independent from the others
Both front wheels and rear wheels have suspension
The front riders are riding leaned back as in modern recumbent bikes
The design of the Quattrocycle is protected by a patent and design rights and may
therefore not be copied without the written permission of Quattrocycle BV.
This guide describes instructions for use, safety and maintenance of the
Quattrocycle.
In case of lending or renting of the Quattrocycle, the person providing the
Quattrocycle has to instruct the user on the safe use of the Quattrocycle.
Quattrocycle BV is not liable for personal injury or damage arising from use of the
Quattrocycle if regulations as contained in this manual are not observed.
Keep this manual for future reference.

Instructions for use and safety
2.1 Who sits where on the Quattrocycle
The Quattrocycle has 4 adult seats. The seats can be shifted on the frame, with the
distance to the pedals to fit the leg of the rider. Older children can also sit on the
Quatrocycle. The front seats are about 40 cm adjustable so that children from about
6 years can already ride. The rear seats are about 30 cm adjustable, so here kids
can ride from about 8 years.
The person who sits left at the rear left seat has to brake and steer. This should
always be an adult with enough length to have good visibility to the entire bike,
road and other traffic. Controlling the Quattrocycle without sufficient overview
is dangerous for the riders of the Quattrocycle and for other road users.
The adult seats do not have seat belts. People who cannot ride safely without
belts (eg children under 6 years) should not sit on these seats.
Only 1 person should sit on a seat. This also applies for children or one adult with
one child.
Adults are only allowed to ride the Quattro Cycle in the four adult seats. Riding in a
different location (e.g. on the luggage rack) is dangerous.
2.2 Adjustment of the seats
The seat must be placed at a distance from the pedals such that can you can ride
comfortably. This goes as follows:
1. Unlock the clamp by pulling the clamp arm toward you and then moving it down.
The seat is now loose on the frame
2. Move the seat to the desired position
3. Lock the clamp by pushing the clamp arm back.
4. Make sure the seat is firmly on the frame
Warning:
Do not adjust seats while riding! It can cause dangerous situations which
could result in personal injury.
2.3 Getting on the Quattrocycle
Getting on the Quattrocycle is done as follows:
1. Stand near the pedals belonging to the place where you want to sit
2. Move one leg over the frame beam to which the pedals are attached
3. Move back to sit in the seat

Quattrocycle BV
User Manual Quattrocycle 5
Do not step on sensitive parts as the steering mechanism or the chain covers. These
can deform if you do this.
2.4 Taking young children on the Quattrocycle
As described in Section 2.1, children who can ride independently can sit on the seats
of the Quattrocycle. Smaller children can ride on the back of the Quattrocycle in child
seats mounted in the square holes in the luggage rack. There are two types of child
seats:
For children up to 15kg a special approved child seat (eg Bobike) with three point
belts should be used. This seat can be mounted on the luggage rack by using a
special bracket that is mounted in one of the square holes in the luggage rack.
Children between 15 and 25kg can ride in child seats mounted on the luggage
rack. These have a lap belt. Besides separate child seats one can also use a
bench for three children with lap belts.
Warning:
Children should always wear safety belts to prevent they can stand while
driving and to prevent that they can fall off the bicycle during braking or taking
turns.
Children should never ride the Quattrcycle on a different place than in a child
seat (e.g. on the luggage rack).
Always lock the child seat with the included spring clip. The child seat can
never be detached from the frame of the Quattrocycle then.
2.5 Taking luggage on the Quattrocycle
The Quattrocycle has a luggage rack at the rear side for carrying luggage. Luggage
should be secured on the rack such that it cannot fall off during riding.
No other places on the Quattrocycle are suitable for taking luggage because the
drive system, steering system or brakes can be blocked by this.
2.6 Maximum load of the Quattrocycle
The Quattrocycle is designed for people till 100 kg. The use of the Quattrocycle by
heavier persons can lead to damage to the Quattrocycle and accidents.
The child seats on the luggage rack are suitable for children till 25 kg.
The maximum total weight on the luggage rack is 75kg. This means one can take
75kg of luggage, reduced by the weight of the children on the child seats on the
luggage rack.
2.7 Steering the Quattrocycle

Quattrocycle BV
User Manual Quattrocycle 6
Steering of the Quattrocycle is done by two handle bars. To steer left, move the left
handle bare to the rear and the right handle bar to the front. To steer right, move the
left handle bar to the front and right handle bar to the rear.
The brakes in the front wheels are operated by pushing both handle bars to the front.
The rear brakes are operated by the brake levers on the handle bars. These brake
levers should always be operated simultaneously to prevent the Quattrocycle to pull
to one side.
The braking distance is minimal if all brakes are operated simultaneously by
operating the brake levers and pushing the handle bars to the front.
Warnings:
As steering and operation of the brakes are different compared to normal
bikes, riders should get acquainted to this while standing still before riding.
Always check that the Quattrocycle is fully OK before riding; the functioning
of the steering and brakes in particular.
Always check before riding that everyone is well seated, with the children in
the child seats having their seats belts fastened.
2.8 Riding in reverse
For maximum comfort and safety, the Quattrocycle has a freewheel. By application of
this freewheel, one cannot ride in reverse by pedaling in reverse. If riding in reverse
is required, it can be done by the persons on the rear seats by stepping with their feet
on the ground.
Warning:
Ride in reverse only at a very low speed! The freewheels only work when riding
forward. When riding in reverse, people can get trapped by pedals and chains
turning in reverse. Never ride down on a slope in reverse!
Riders are warned for this danger by warning stickers on the Quattrocycle. The
standard warning stickers are in Dutch. Replace these by warning stickers in
other language(s) depending on the nationality of the riders. Always check that
riders do understand the warning stickers before riding. Make sure the stickers
are well readable en replace them when they are damaged.
2.9 On the road with the Quattrocycle
The Quattrocycle complies with all requirements to vehicles in the Netherlands. In
this way, the Quattrocycle is permitted as vehicle in the Netherlands. Other countries
or even areas may have different requirements. You need to check if the
Quattrocycle fulfills all requirements in the area you want to use the Quattrocycle.
When riding the Quattrocycle, normally the same traffic rules apply as for a normal

Quattrocycle BV
User Manual Quattrocycle 7
bike. You should check however that this is the same in you area.
For riding the Quattrocycle safely, follow the following rules:
Everyone should remain seated with feet on the pedals during riding. If feet are
not on the pedals, they can get trapped between the Quattrocycle and the ground.
If people cannot keep their feet on the pedals (e.g. handicapped), you should tie
their shoes to the pedals. (Special foot pedals are for sale in our webshop).
Children in the child seats on the luggage rack should remain seated while riding.
Always fasten the seat belts to enforce this.
Take curves at low speeds to prevent capsizing of the Quattrocycle and people to
fall off.
Do not ride on steep hills or uneven terrain. The Quattrocycle is designed to ride
on terrain with a maximum unflatness of 30 cm. At a higher unflatness, the frame
can be damaged.
A Quattrocycle without lighting (standard model) may not be used at night or at
daytime with bad visibility.
Do not use alcohol or drugs before or during riding the Quattrocycle.
2.10 Parking
Always park the Quattrocycle on flat terrain and use the park brake. The park brake
is applied by applying the brake levers on the handle bars and then blocking them by
pushing the grey button. You can release the park brake by applying the brake levers
once again.
The Quattrocycle does not come with a lock standard. To prevent theft, you can use
standard locks as used for bikes, mopeds or motor cycles.
If you do not use the Quattrocycle for a long time, you can choose to store it upright
to save space. To do this, remove the child seats from the luggage rack and place
the storage bracket (option) in the square tubes in the luggage rack. Lock the storage
bracket with spring clips. Apply the park brake and lift the front of the Quattrocycle till
it rests on the storage bracket.
Warning:
When the Quattrocycle is stored upright, it can easily fall. Always secure it to
e.g. a wall using a rope or chain.
2.11 Other points of attention
Wear suitable clothes to ride the Quattrocycle. Do not wear a long coat or scarf; they
can easily get trapped between the chains or under the wheels. Always wear shoes
to ride the Quattrocycle.
A Quattrocycle is not a toy for children. Do not let hem climb on it or play with it in any
way.

Chapter 3
Maintenance
The Quattrocycle should be checked by a bike mechanic after transportation and
after each 500 to 1000 km of riding. The check points are described in the following
chapters.
3.1 Tensioning the chains
The chains will gradually elongate during riding. Therefore they need to be checked
and tensioned time by time. In particular new chains will initially elongate
considerably. Therefore, tensioning the chains for the first time will be needed quite
soon, typically after something like 20 km.
Tensioning the chains is done as follows:
1. Tensioning of the two rear chains:
Remove the gear shifter from the rear gear hub using an allen key.
Loosen the nuts of the gear hub
Move the gear hub to the front until the chain is tight and tighten the nuts.
Put the gear shifter back on the gear hub.
2. Tensioning the chains between the two gear hubs. This is done by moving the
front gear hub to the front, in the same we as done for the rear hub in step 1.
3. Tensioning of the four chains between the gear hubs and the crank stets:
Loosen the M4 bolt that connects the chain cover to the frame a couple of
turns so that the chain cover can move through the slotted hole in the frame.
Loosen the M8 bolts that connects the crank shaft housing to the frame a
couple of turns.
Move the crank shaft housing to the front till the chain is tight.
Tighten the M8 bolts.
Tighten the M4 bolt at the rear of the chain cover.
Starting 2009, Quattrocycles have automatic chain tensioners on all chains except
the chains between the rear crank set and the rear gear hubs. The above procedure
is then only needed for these chains and for the other chains once the automatic
tensioners are at the end of their range.
3.2 Checking of the brakes
The Quattrocycle has 4 mechanically operated drum brakes. The brakes need to be
checked frequently, also the park brakes on the brake levers. After some time the
brake cables will elongate somewhat and the brake shoes will wear, then the brake
cables need to be readjusted using the adjustment screws at the wheels to keep the
right braking performance. Brake cables that show wear and worn out brake shoes
need to be replaced in time to keep a good braking performance.
3.3 Checking of the steering

Quattrocycle BV
User Manual Quattrocycle 9
Check the steering mechanism. The steering mechanism may only have little play. If
the play becomes too large, the ball joints or the nylon bearing bushes need to be
replaced.
The alignment of the front wheels needs to be checked as well. Badly aligned front
wheels cause a higher rolling resistance and accelerated wear of the front tires.
Check the alignment by measuring the distance between the wheels at the front and
at the rear. If these distances are not the same, the alignment can be fixed by
elongating or shortening the steering bars that run parallel to the front axle. The
length can be changed by loosening the ball joint at one side and than rotating it.
3.4 Tires
The right tire pressure is important for the rolling resistance of the Quattrocycle. The
recommended pressure is 2.5 bar.
Tires with insufficient profile should be replaced by new ones of the same size.
3.5 Checking of the freewheels
The Quattrocycle has six freewheels. Four freewheels are integrated in the gear
hubs. The other two are on the rear axle. These freewheels are needed for safety. If
a rider would get trapped between the chains (e.g. with his cloths), the chains will
stop turning while the Quattrocycle is still riding. Therefore the Quattrocycle may only
be used with well operating freewheels. In particular the freewheels on the rear
axles may be blocked at no time.
3.6 Reflectors
The Quattrocycle has the following reflectors:
2 white reflectors at the front
4 yellow reflectors at the sides
2 red reflectors at the rear
2 reflectors in each pedal
These reflectors improve the visibility of the Quattrocycle in traffic and are required by
law. Check that all reflectors are clean and undamaged. Replace damaged or
missing reflectors.
3.7 Fixation of the seats
The seats on the Quattrocycle are clamped on the frame beams by means of a cam
clamp. During clamping, the seat is first pulled down on its feet on the frame beams.
Subsequently the seat is clamped horizontally against the side of the frame beam.
The seat clamp may need to be adjusted later because of wear or overload.

Quattrocycle BV
User Manual Quattrocycle 10
If the vertical clamping is insufficient, follow these steps:
Loosen the seat clamp
Loosen the 2 M8 nuts of the clamp a couple of turns (see photo below)
Move the part of the seat clamp that is located in the frame beam up
Fasten the 2 M8 bolts firmly
Tighten the seat clamp again
If the horizontal clamping is insufficient, follow these steps:
Loosen the seat clamp
Tighten the long M6 bolt under the frame beam somewhat
Tighten the seat clamp again
If the seat is clamped with high force to the frame, but it can still move sideways, the
horizontal clamping only happens at the top or bottom of the clamp block. One can
check with a feeler gauge whether the clamp block is in contact with the frame beam
over the full height. If one side is not touching the frame beam, use the M8 nuts at
that side to push the clamp block further to the frame beam.
Check that the clamping force is sufficient to mount the seat stably on the frame.
Also check the connection of the child seats on the luggage rack.
Check the condition of the seat belts. Only use the child seats with properly working
seat belts.
3.8 Adjustment of the gears
In order to shift gears, the shifter cable needs to be well adjusted. You check the
adjustment by shifting to the second gear. On the gear shifter the yellow bracket
inside should be exactly between the two yellow stripes on the housing (see photo).
The adjustment can be made with a cable adjustment screw on the gear shifter.
