Please read all information in this manual
carefully in order to gain maximum
performance, safety and enjoyment from your
Lafree electric bicycle.
Congratulations! You have just pedalled into
the exciting world of electric power assistance
for bicycles. In addition to being a full-featured
bicycle, Lafree has an integrated on-board
electric power assist unit. The power assisted
pedal and Variable Power Control (VPC
Throttle) systems are both easy to use and
understand. However, due to their
sophisticated technology, it is extremely
important that you follow the directions for
their operation carefully and completely.
Failure to do so could cause damage to the
motor, energy set (battery pack/charger unit),
VPC Throttle components, or the entire
bicycle.
Even though Lafree functions as a standard
bicycle, you should still review the chapters on
bicycle operation, especially if you haven’t
ridden/owned a bicycle within the last 10
years. Component performance and
configuration has changed dramatically, and
while they are easy to use and understand,
they may not look quite the same as what you
are familiar with! Taking a few moments now
to understand Lafree’s operating procedures
will help you get the most out of every ride.
Please read chapter 6, “Charging the Energy
Set” before operating Lafree’s electric
powered functions. Lafree’s Energy Set
(Battery Pack/Charger Unit) must be charged
completely before motor (power assisted
pedal, Variable Power Control) can be
operated.

The Lafree power assisted electric bicycle is a
new approach to cycling, bringing together
human power and the power of electronic
technology to create a totally new cycling
experience!
Lafree’s exclusive power assisted pedal
system and Variable Power Control (VPC
Throttle) enhance the enjoyment of riding an
ordinary adult bicycle by giving you an extra
boost for climbing hills or riding into a
headwind-all automatically, efficiently, and
instantly.
Lafree’s advanced on-board torque/speed
sensor automatically adjusts to rider input and
determines how much assistance is needed.
The VPC Throttle feature allows you to
manually override power assisted pedal for
extra and/or prolonged assistance.
PAP: Power-Assisted Pedal
Simply turning the power on activates Power-
Assisted Pedalling. A torque sensor, housed
within the gearbox, “senses” the rider’s input.
The electric motor then responds with
measured power. Pedal input is required for
motor output.
VPC: Variable Power Control
(VPC Throttle)
Variable Power Control allows you to fine-tune
the features already available in the Power-
Assisted mode. You control the amount of power
output simply by twisting the VPC Throttle.
3.1 Frequently Asked
Questions (FAQ’s)
Q: Do I need any special skills or licenses to
ride Lafree?
A: Special permits or licensing may be
required to operate Lafree. Check with your
national regulations. In all instances, it is
essential that you know how to ride a
standard bicycle before attempting to ride
Lafree.
Q: What is the “range” of Lafree’s Energy Set?
A: Your range will vary depending on the road
surface and how much you use the
Variable Power Control (VPC Throttle). The
range of the Energy Set at full VPC Throttle
output on flat terrain with no headwind is
approx. 30-40 km.
Q: How long does it take the Energy Set to
fully charge?
A: Approximately four hours (when battery
has less than 1% remaining energy).
Q: Will the motor assist continue when I put
on the brakes?
A: No. This important safety feature shuts the
motor off any time the brakes are applied.
To resume power assist, simply start
pedalling.

WHAT IS LAFREE ?
2.3 Position of the Serial
Numbers
Please record Lafree’s bike serial number and
battery serial number for future reference. The
serial number of the bike is stamped into the
left rear “dropout” of the frame. The dropout is
the piece of frame that holds the left-side axle
of the rear wheel (Fig 2E).
FIGURE 2E
0288 Opm Binnenwerk 11-02-2000 10:46 Pagina 6

Q: How many charges will the Energy Set
accept before needing replacement?
A: Lafree’s lead acid battery can be charged
from 300-400 times before replacement.
Q: What are the advantages of the sealed
lead acid battery set that Lafree has
chosen?
A: The lead acid battery uses “deep cycle”
technology, allowing the chemical reaction
to occur within the battery without the need
for an alternator, such as with a car or
motorcycle. This means that the energy is
recycled through the battery each time it is
charged, making it more efficient and safer
to handle.
Q: Can I ride Lafree without the battery?
A: Although Lafree can be ridden as a
standard bicycle, it is strongly
recommended that you do not ride without
the Energy Set in place. If you DO choose
to ride without the Energy Set, do not place
any items in the energy set compartment
other than the energy set as damage may
occur to the battery leads.
Q: Where can I charge my Lafree?
A: Lafree’s Energy Set can be charged at any
110/240 volt grounded electrical socket.
Q: What happens when the Energy Set
becomes depleted?
A: When the energy level in Lafree’s battery
reaches one percent of maximum capacity,
the battery needs to be re-charged. Simply
plug Lafree’s power cord into any approved
power outlet (see Section 6.1,Charging the
Energy Set).
Q: Will temperature effect the range of
Lafree’s Energy Set?
A: Extremes in heat and cold may effect
maximum energy range (see Section 6).
Q: What is the maximum speed of Lafree?
A: The maximum speed under full VPC
Throttle assist is 25km/h. Once Lafree has
reached or exceeded 25km/h, the motor
will automatically disengage until the speed
falls below 25 km/h.
Q: Can I ride my Lafree in the rain or through
puddles?
A: Yes. However, you should not spray water
directly at any of the electrical components,
which include the Energy Set, motor, VPC
Throttle, and energy indicator.
Q: Does an electric bicycle require any special
maintenance?
A: The standard bicycle parts can be serviced
by the owner if the correct tools are used.
However, there is no user serviceable
components in the Energy Set, drive motor,
or VPC Throttle components. We
recommend that you follow the service
schedule and take your Lafree to an
authorised Lafree dealer periodically.

which you’ll be riding, and with feet shoulder
(pedal) width apart. If the top of your inseam
(crotch) touches the frame, the bike is too big
for you.
4.1.2 Saddle Position
Saddle height and position are extremely
important factors in determining your comfort
and performance. Due to Lafree’s unique
hinged saddle, fore/aft saddle position is fixed.
However, the most important aspect of saddle
position - saddle height - can and should be
adjusted for maximum comfort and pedalling
efficiency.
4.1.2.1 Height Adjustment
Put your heel on the pedal at its lowest
position. Your leg should be stretched with a
slight bend in the knee. Use this as a rule of
thumb. If you do not feel comfortable, slight
adjustments may be necessary.
To adjust the saddle height: Loosen the seat
binder quick-release cam lever (Fig. 4B; see
also Section 7.8 on Seat Post Quick-Re-
leases) and move the seat post up or down as
required. Re-tighten the seat binder, securing
it so that the post does not twist. Check the
adjustment as described above. Under no
circumstances should the seat post protrude
from the frame beyond its “Minimum Insertion”
or “Maximum Extension” mark (Fig. 4C).

BIKE SIZING AND SAFETY
FIGURE 4B
4.1 Size
WARNING: A bike that is too big or too
small for the rider can be difficult to
control and can be uncomfortable. If
your bicycle does not fit properly, you
may lose control and fall.
4.1.1 Frame size
Lafree’s sloping “primary frame tube” allows
for greater standover clearance for a wide
variety of riders (clearance between primary
frame tube and top of inseam while straddling
the bike just in front of the saddle). Your
dealer will have made sure you had the
correct standover clearance, based on
physical examination. If someone else
selected a Lafree for you, as a gift, for
example, it is important to have the correct
standover clearance before attempting to ride
it (Fig. 4A). If you cannot stand flat-footed with
feet at shoulder width without coming into
contact with the primary frame tube, we
strongly suggest that you do not attempt to
ride Lafree.
To check for safe standover height, straddle
the bike while wearing the kind of shoes in
FIGURE 4A
0288 Opm Binnenwerk 11-02-2000 10:46 Pagina 8

WARNING: If the seat post protrudes
from the frame beyond the Minimum
Insertion or Maximum Extension mark
(see Fig. 4C) the seat post may break,
which could cause you to lose control
and fall. Riding Lafree with the seat
post protruding from the frame beyond
the Minimum Insertion or Maximum
Extension mark can also damage the
frame.
WARNING: After any saddle
adjustment, be sure to tighten the
saddle adjusting mechanism properly
before riding. A loose seat post binder
can cause damage to the seat post, or
can cause you to lose control and fall.
Periodically check to make sure that
the saddle adjusting mechanism is
properly tightened.
4.1.3 Handlebar Height and Angle
4.1.3.1 Handlebar position
The position of the handlebar is important for
comfortable cycling. When adjusting handle
bar position, refer to torque setting table at
section 8.2.
WARNING: The stem’s Minimum
Insertion Mark must not be visible
above the top of the headset (see Fig.
4D). If the stem is extended beyond the
Minimum Insertion Mark the stem may
damage the fork’s steerer tube or
break, which could cause you to lose
control and fall.
9
Handlebar position can be adjusted as follows
4.1.3.2 Handlebar stem height
There is no general rule for the height of the
handle bar. For a more sportive riding
position, choose a lower position. For a more
recreational riding position choose a higher
position. To adjust the handlebar height:
loosen the stem binder bolt (Fig 4D) three or
four turns. Tap the bolt carefully down, using a
plastic or wooden hammer. Set the handlebar
stem at the correct height and perpendicular
to the front wheel. Fasten the bolt to the
correct torque.
4.1.3.3 Handle bar angle
By tilting the handle bar you can direct the
grips more upward or downward. This is a
matter of personal taste. Loosen the bolt at
the front side of the handle bar stem. Tilt the
handle bar to the required position. Fasten the
bolt to the correct torque. Check and if
required adjust the position of the brake
levers.
4.1.3.4 Handle bar stem angle
Some models are equipped with an adjustable
handle bar stem. This allows you to adjust the
angle of the handle bar stem extension.
Loosen the inclination bolt and set the
extension to the required inclination. Fasten
the bolt to the correct torque. Check and if
needed adjust the position of the brake levers.

4.2 Safety Equipment
WARNING: Many countries require
specific safety devices. It is your
responsibility to familiarise yourself
with the laws where you ride and to
comply with all applicable regulations,
including properly equipping yourself
and your bike as the law requires.
4.2.1 Reflectors
Reflectors are important safety devices which
are designed as an integral part of Lafree.
The reflectors are designed to pick up and
reflect street lights and car lights in a way that
helps you to be seen and recognised as a
moving bicyclist.
CAUTION: Check reflectors regularly to make
sure that they are clean, straight, unbroken
and securely mounted. Have your dealer
replace damaged reflectors and straighten or
tighten any that are bent or loose.
4.2.2 Lights
If you ride your bike after dusk, your bicycle
must be equipped with lights so that you can
see the road and avoid road hazards; and so
that others can see you. Vehicle laws treat
bicycles like any other vehicle, which means
an illuminated white front, and a red rear light,
not just reflectors, if you are riding after dusk.
A properly fitting lighting system is being
offered as a Lafree optional accessory.
Please ask your dealer.
4.3 Mechanical Safety Checks
Lafree is equipped with several unique safety
features, described in more detail in section 7.
• Speed Actuated Motor Shut-Off-
Automatically disengages motor when
Lafree reaches 25 km/h.
• Brake Actuated Motor Shut-Off-
Automatically disengages motor when one
or both brakes are applied.
• Automatic Key Lock-Locks Energy Set into
place when ignition is at ON position.
• Self Diagnostic Sequence-Automatically
checks that VPC Throttle, Brake Actuated
Motor Shut-off, and the torque sensor are
functioning.
• Safety switch disables the motor-electric
assist simply by flipping the handlebar
mounted switch to the off position.
Please be sure to familiarise yourself with
these features before operating Lafree. Here
is a simple, sixty-second mechanical safety
check which you should get in the habit of
making every time you’re about to get on
Lafree.
4.3.1 Diagnostic Readout
Lafree is equipped with a five-point diagnostic
check of the electronic features:
• front and rear brake motor cut-off function
• VPC Throttle function
• torque sensor function
• speed sensor function
To initiate diagnostic sequence, turn ignition to
ON position and push Self-Diagnostic button.
4.3.2 Nuts & bolts
Inspect the bike closely from front to rear for
any obvious signs of worn or broken
components. Grasp the handlebar with both
hands and lift the front wheel off the ground
about 5-10 centimetres, then let it drop firmly
on the ground while still holding the
handlebar. If anything sounds, feels or looks
loose, do a quick visual and tactile inspection
of the whole bike. Try to find the source of
noise or any obvious loose components, and
secure them. If you’re not sure, ask someone
with experience to check, or take your Lafree
to your authorised service centre.
4.3.3 Tyres & Wheels
Check proper tyre inflation by placing your
hand directly on top of each individual tyre.
With a straight arm and direct downward
pressure, push on the tyre with downward
body weight and watch the spot where the
tyre is contacting the ground. There should be
very little tyre compression. If your tyres need
10
0288 Opm Binnenwerk 11-02-2000 10:46 Pagina 10

inflating, use a standard bicycle floor pump. If
you must use a high-volume compressor like
those found at automotive service stations,
add air in small amounts as these
compressors are designed to fill auto tyres
which have much larger volumes than bicycle
tyres. A surge of pressure could cause the
innertube to explode, which can cause severe
damage to the tyre and serious injury.
Spin each wheel slowly and look for cuts in
the tyre’s tread and sidewall. Replace
damaged tyres before riding the bike.
Spin each wheel and check for brake
clearance and side-to-side wobble of the rim. If
a wheel wobbles side to side or contacts the
brake shoes (front brake only), take the bike to
a qualified dealer to have the wheel aligned.
CAUTION: Wheels must be “true” (aligned)
for the brakes to work effectively. Wheel truing
is a skill which requires special tools and
experience. Do not attempt to true a wheel
unless you have the knowledge and tools
needed to do the job correctly.
4.3.4 Brakes
Lafree offers models with rim brakes (Fig 4E,
4F) and with disc brakes. Visually inspect for
proper cable routing.
Squeeze the brake levers. Brake levers
should engage hoes/rear roller brake at
approximately half way through their arc, or
within about 2,5 centimetres of handlebar grip.
To check proper brake lever travel, encircle
the hand grip with your thumb and forefinger,
then squeeze the brake lever with the
remaining three fingers of each hand. If you
can squeeze the levers so that they touch
your forefinger, you should have a qualified
service centre adjust your brakes.
Make sure that the front brake’s brake shoes
are contacting the rim’s braking surface fully
(Fig. 4H). Also check that the shoes are not
coming into contact with the tyre’s sidewall
whilst applying the brake. Riding the bike with
brake shoes contacting the sidewall can
cause the tyre to be damaged and the
innertube to puncture, which may cause you
to lose control and fall. Do not ride the bike
until the brakes are properly adjusted. See
Section 7.9 for details.
WARNING: Riding with improperly
adjusted brakes or worn brake shoes is
dangerous and can result in serious
injury.
Please see the attached owners manual for
information on disc brakes.
11
FIGURE 4E
FIGURE 4F
0288 Opm Binnenwerk 11-02-2000 10:46 Pagina 11

4.3.5 Quick-Releases
Check to see that the front and rear wheel
and seat post quick-release levers are
properly adjusted and in the CLOSE position.
See Section 7.7+ 7.8 for details.
WARNING: Riding with an improperly
adjusted wheel quick-release can
cause the wheel to wobble or
disengage from the bicycle, which can
cause damage to the bicycle or serious
injury.
4.3.6 Handlebar and saddle alignment
Are the saddle and handlebar stem correctly
in line with the bike’s top tube and tight
enough so that you can’t twist them out of
alignment?
4.3.7 Handlebar ends
Are the handlebar grips secure and in good
condition? If not, replace them. Are the
handlebar ends plugged? If not, plug them
before you ride.
You are now ready to safely ride your Lafree.
However, we suggest that you take a few
moments to review the following chapters on
riding tips and safety, especially if you have
not ridden a bicycle in a long time.

NOTE: Riding a bicycle involves certain risks,
including damage and injury. By choosing to
ride a bicycle, you assume personal
responsibility for those risks. The people who
sold you the bike, the manufacturer, the
distributor, and people who manage or
maintain the roads and trails you ride on are
not responsible for your actions. Therefore, it
is extremely important that you understand-
and practice-the rules of safe and responsible
riding, and to use common sense whenever
possible and applicable.
5.1. The Basic
Carry out the Mechanical Safety Check
(Section 4.3) before you attempt to ride
Lafree, In addition, make sure that you always
follow the electronic diagnostic procedure for
Lafree’s power assist features.
5.2. Rules of the Road
1. Learn the local bicycle laws and
regulations. Many countries have special
regulations about licensing of bicycles, riding
on sidewalks, laws regulating bike path and
trail use, and so on. Many countries have
helmet laws, child carrier laws and special
bicycle traffic laws. In most countries, a
bicyclist is required to obey the same traffic
laws as the driver of a car or motorcycle. It is
your responsibility to know and obey the laws.
2. Some Lafree models are equipped with a
front suspension (suspension fork). When
braking, the front suspension compresses and
the front end may drop noticeably. You could
lose control and fall if your riding skills are not
sufficient to negotiate this mechanical function
of the suspension fork. Familiarise yourself
with your suspension by practising braking in
a safe area on flat ground before riding at
higher speeds over varied road surfaces.
5.3 Wet Weather Riding
Under wet conditions, the stopping power of
your brakes (as well as the brakes of other
vehicles sharing the road) is dramatically
reduced, and tyre-to-surface adhesion
(“traction”) is also compromised. This makes it
harder to control speed and easier to lose
control. Whenever wet conditions are present,
reduce speed and apply your brakes earlier
and more gradually than you would under
normal, dry conditions.
5.4 Night Riding
Riding a bicycle at night is much more
dangerous than riding during the day.
WARNING: Riding at dusk, after dark or
at times of poor visibility without a
bicycle lighting system which meets
national laws and without reflectors is
dangerous and can result in accidents.
Before riding at dusk or at night, take the
following steps to make yourself more visible:
• Make sure that your bicycle is equipped
with correctly positioned and securely
mounted reflectors (see Section 4.2.1,
“Reflectors”).
• Make sure that lights and reflectors are not
obstructed by your clothing, accessories, or
anything you may be carrying on the
bicycle.

6.1 Charging the Energy Set
(lead acid battery)
Lafree’s portable Energy Set has a self-
contained charger, allowing charging of the
battery virtually anywhere, with or without the
bicycle. Although Lafree can be ridden as a
standard bicycle, it is strongly recommended
that you do not ride without the battery pack in
place.
CAUTION: If riding Lafree without the Energy
Set, do not place any items in the energy set
compartment other than the energy set as
damage may occur to the battery leads.
To charge the battery while Energy Set is
on the bicycle:
Turn ignition to the OFF position.
Park Lafree by placing Lafree’s support stand
in its down and locked position. Charging area
should be level, with good ventilation. Do not

place Lafree or the Energy Set in direct
sunlight, near a heat source (water heater,
furnace, fireplace, etc.), or in contact with
moisture while charging (Fig. 6A).
CAUTION: Do not attempt to charge Lafree’s
Energy Set in temperatures below 0 degrees
Celsius or above 40 degrees Celsius.
WARNING! Do not touch battery while
charging is taking place as battery can
reach temperature of up to 50 degrees
Celsius.
Lift the Energy Set’s charging cord cover,
grasp the plug, and pull to extend cord. If the
cord is difficult to extend or is jammed, do not
pull on plug with force.
Insert the plug into the electric outlet, making
sure that all pins are inserted fully into the
socket. Keep outlet area well ventilated and
free from debris to avoid fire from sparks or
overheating.
When plug is inserted into outlet, the Energy
Set’s red power light (located on right side of
Energy Set below charging cord) will
illuminate, indicating that electricity is flowing
to the battery. This also indicates that energy
level is at or below 80 percent of full charge.
When charging is at or above 81 percent, the
green power light (located next to red power
light), will illuminate. Battery will reach full
capacity after approximately four hours. See
chart in this section for charging times.
Lafree’s Energy Set is equipped with “floating
charge” circuitry. Charging Energy Set after
maximum capacity has been reached will not
harm the battery.
Be aware that the output of a fully charged
battery set may vary approx. 10%. As a
consequence this varies the autonomy.

Release the saddle’s hinge mechanism by
pushing on the lever located under the rear
portion of the saddle (Fig. 6B). Lift up on the
saddle and tilt it forward until the saddle is
vertical (Fig. 6C).
Lift the Energy Set’s retractable sliding
carrying handle and pull up with one hand,
supporting the bottom of the Energy Set with
the other hand once it clears the Energy Set
compartment (Fig. 6D).
Tilt the saddle back to its horizontal and
locked position.
When replacing the Energy Set, make sure
the charger cord/power lights are on the right
side (visible from the riding position) as you
slide the Energy Set into its compartment.
Carefully align the guide plate on the rear of
the Energy Set with the compartment’s
grooves and slowly slide the Energy Set into
place. You will hear a “click” indicating the
base of the Energy Set is contacting the
bottom of the compartment and battery leads.
To store the Energy Set
Before storing, charge the battery to its
maximum capacity. The Energy Set will
discharge automatically and completely after
three months. If you have stored the Energy
Set for longer than two months without
charging, discharge and recharge the battery.
(Please repeat this every two months.)
In case you forgot to discharge your battery
after 2 months, a new recharge will be
necessary. Your dealer will have the
necessary equipment available in order to
carry out this task for you.
WARNING: Leaving the Energy Set in a
discharged state for longer than three
months may effect the long-term life of
the battery. Store Lafree/Energy Set in
the OFF position. However, if left in the
ON position, “automatic sleep” will
engage after 10 minutes.
CAUTION: Store Energy Set in a low, cool,
dry, level, secure area with good ventilation
and away from any heat source.
If storing Lafree with Energy Set in place, turn
ignition to OFF position. Leaving ignition in the
ON position while stored or parked will result
in more rapid energy loss.
6.2.2 Transporting Lafree
When transporting Lafree, it is best to remove
the Energy Set as it is easier to lift and
manoeuvre the bicycle.
CAUTION: Never lay Lafree on its side with
the Energy Set in place as damage to the
lead acid battery can occur, as well as
leakage of acid that can cause injury to body
FIGURE 6D
FIGURE 6C

parts or damage to items and surfaces it may
contact. It is also best not to lay Lafree on its
side in any case, as doing so can cause
damage to the control components, motor
housing, pedals, crank arms, and wheels.
6.3 Care & Maintenance
There are no user-serviceable parts in the
Energy Set. If you suspect a problem, take
Lafree and Energy Set to your authorised
Lafree dealer.
When cleaning the Energy Set casing, use a
cloth moistened with water only. Do not use
solvents or cleaning solutions of any kind.
Lafree’s lead acid battery must be disposed of
or recycled properly. When the battery will no
longer hold a charge, you must take it to your
authorised Lafree dealer for replacement.
Your authorised Lafree dealer is equipped to
dispose of the battery according to local and
other laws.
CAUTION: Please read the following general
safety tips for care and maintenance of
Lafree’s Energy Set:
• Do not place Energy Set into a fire or near
intense heat source as it can explode and
cause serious injury.
• When cleaning the Energy Set casing, use
a cloth moistened with water only. Do not
use solvents or cleaning solutions of any
kind.
• Do not attempt to open Energy Set’s battery
case or charging unit. There are no user-
serviceable parts in the Energy Set. If you
suspect a problem, take Lafree and Energy
Set to your authorised Lafree dealer.
• Inspect the Energy Set periodically for
cracks, unusual residue, or other abnormal
appearance. Do not operate Energy Set
with cracks or breaks in the casing.
• Do not attempt to use Energy Set as a
power supply for anything other than Lafree.
• Always pull gently on the charging cord.
Never yank or extend past its full length. To
remove from power outlet, pull on the plug,
not on the cord.
6.4 Radius of action
The radius of action is the distance you can
cycle using the power assistance. The Lafree
radius of action depends on two factors:
• the battery capacity
• the cycling circumstances and maintenance
of the bicycle
Under the best possible circumstances, you
can cycle approx. 30-40 km using the power
assistance system. However, the following
factors can influence the radius of action of
your Lafree:
• the temperature
• the wind
• the weight of the rider and loading
• the number of stops and starts
• the terrain (flat, steep hills or slopes,
pavement)
• the quality of tyres and chain

It is extremely important to the performance,
enjoyment and safety of Lafree and yourself
to understand how many of the features of
Lafree operate. You should not assume that
the way things have worked on previously
owned bicycles operate similarly on Lafree,
even if you’re an experienced bicyclist. Be
sure to read - and to understand - this section
of the owner’s manual. If you have even the
slightest doubt about how any of the
mechanical features of Lafree operate, talk to
your authorised Lafree dealer.
7.1 Variable Power Control
(VPC Throttle)
Lafree’s Variable Power Control (VPC) Throttle
gives you instant access to the motor’s power
for going up hill or into a headwind, or if you
simply don’t want to use any of your own
power! You control the amount of power output
simply by twisting the right VPC Throttle.
Twisting the VPC Throttle in a
counterclockwise direction against the grip’s
spring tension (rearward) applies power from
the electric motor, while releasing the grip in a
clockwise direction (forward) decreases power
from the electric motor (fig. 7A).
The ignition-lockset and safety switch must be
ON. Lafree requires pedal input for motor
output. This means that under any pedal
exertion, Lafree will respond with electrical
assistance. You can control the amount of
power output simply by twisting the VPC
Throttle, which is located on the right side of
the handlebars.
When your speed reaches or exceeds 25 km/h,
Lafree’s motor will automatically disengage and
stop assisting until the speed drops below 25
km/h. You must pedal to enable the motor to
engage VPC Throttle. If you stop pedalling
while VPC Throttle is in the ON (twisted
counterclockwise) position, motor assist will
cease until pedals begin turning again. The
throttle must also be twisted completely
clockwise (no power) then twisted counter
clockwise again for VPC Throttle to engage.
For safety, do not pedal Lafree while the bike
is leaned over in a turn and VPC Throttle
engaged, as the pedal may come in contact
with the ground or other elevated obstacle. It
is best to put the pedals parallel to the ground
at nine and three o’clock, or with the inside
pedal (side the bike is leaning toward) at 12
o’clock and the outside pedal at six o’clock.
WARNING: For safety, do not pedal
Lafree while the bike is leaned over in
a turn and VPC Throttle engaged, as
the pedal may come in contact with the
ground or other obstacles and cause
you to lose control and fall.
CAUTION: Using VPC Throttle exclusively
drains energy more quickly. Use VPC Throttle
sparingly for optimum energy range and
consumption.
7.2 Power Assisted Pedal
Lafree’s power assisted pedal system utilises
a fuzzy logic CPU (central process unit) to
provide constantly monitored power
assistance based on speed and pedal force.

19
To engage power assisted pedal, turn ignition
switch to the on position (please read Section
6.2.1, Charging the Energy Set, before
operating Lafree’s electric functions). Begin
pedalling as with a traditional bicycle. Power
assisted pedal will automatically engage. Be
sure to sit down on the bicycle first with both
hands placed on the handle before riding
away. Other ways of getting on and riding
away could lead to dangerous situations.
To attain higher or lower speeds, shift the rear
derailleur into the smaller or larger cogs as
described in Section 7.10, “Shifting The Gears.”
When your speed reaches or exceeds 25
km/h, Lafree’s motor will automatically
disengage and stop assisting until the speed
drops below 25 km/h. You must pedal to
enable the motor to engage power assisted
pedal.
7.3 Energy Set Ignition
For the functioning of power assistance and the
diagnostic features, the energy set ignition
must be switched to the ON position. Please
read Section 6, “Charging the Energy Set”
before operating Lafree’s electric powered
functions.
7.3.1 The ignition switch
Your Lafree comes standard with two ignition
keys to operate the ignition switch. Lafree’s
ignition switch has three positions; OPEN, ON
and OFF (fig. 7B):
• OPEN-Lafree’s electronic features will not
function. The Energy Set can only be
removed when the ignition is in the OPEN
position.
• ON-The Energy Set provides power to the
motor and electric features. The Energy Set
is automatically locked into the Energy Set
compartment when ignition is in the ON
position.
• OFF-Lafree’s electronic features will not
function. The Energy Set is locked into the
Energy Set compartment and the key can
be removed. (Use this feature for maximum
security.)
7.3.2 The safety switch
Aremote ON/OFF switch, mounted to the
handlebars, is integrated into the ignition
system. This is called the safety switch. The
safety switch must be turned to the ON
position before electric assistance can be
provided form Lafree’s motor. The switch can
also be used to momentarily turn the Lafree’s
electric assistance off during use.
Start Lafree by turning the key to the ON
position. Following this, turn the safety switch
to the ON position. You should hear an
audible “Beep.” The amount of stored energy
will then appear as 1-5 lights on the energy
indicator located on the top front of the motor
housing. Five lights on the indicator represent
that Lafree’s Energy Set is fully charged.
CAUTION: When leaving Lafree unattended,
turn ignition to OFF position and remove key.
Leaving ignition in the ON position while
parked will result in more rapid energy loss,
and the potential for theft.
7.4 Self-Diagnostic Check
Lafree is equipped with an on-board five-point
self diagnostic-check of the electronic
features:
• front and rear brake-actuated motor shut-off
function (audible beep sound)
• speed sensor function (audible beep sound)
• VPC Throttle function
• torque sensor function
To initiate self-diagnostic mode, engage
Lafree’s support stand in its down position.
Turn ignition to ON position (there will be a
short beep). The Lafree keys are equipped
FIGURE 7B
0288 Opm Binnenwerk 11-02-2000 10:46 Pagina 19

20
with a pin to activate the self-diagnostic check.
Push and hold Self-Diagnostic switch, the
small black rubberised button located to the
left of the LED string/energy indicator (Fig.
7C). Release pressure on the button after
hearing a long beep, indicating Self-Diagnostic
check is ready to be performed. To perform
diagnostic check, follow the directions below:
• Brake Actuated Motor Shut-Off-Pull on each
brake lever individually. If functioning, a
beep will occur each time the lever is pulled.
•Speed sensor: With the support stand in the
down position, lean the bike over slightly until
the rear tyre comes off the ground. Pedal the
crank arm to get the rear wheel turning. If
speed sensor is functioning, an audible beep
will sound repeatedly as the magnetics on
the magnetic “pie” plate are detected by the
sensors until the wheel stops. Stop the rear
wheel with the rear brake. Do not place the
tyre back in contact with the ground while the
rear wheel is moving.
• VPC Throttle: Rotate the right-hand twist
grip. The VPC-throttle functions properly if all
LED’s light up from 1 to 5, depending on how
far the VPC-throttle is turned up. Should one
LED be skipped or fail to light up completely,
your dealer needs to be contacted.
• Torque sensor: Place Lafree on its support
stand. With one hand, put light pressure on
either pedal while holding the rear tyre with
the other hand and rotate the crank arm
forward until an audible beep is heard.
Some or all of the LEDs may illuminate
depending on how much pressure (torque)
is being applied.
CAUTION: If any of these features fail the
diagnostic check, take your Lafree to an
authorised Lafree dealer immediately.
Operating Lafree with the Energy Set on, but
with any or all of these features inoperable
could cause severe damage to the electronic
circuitry and could cause you to lose control
and fall.
To a) cancel Self-Diagnostic mode, b) re-set
Self-Diagnostic mode, c) to turn on Lafree’s
power assist features after using the Self-
Diagnostic mode - turn the ignition or the
safety switch to the OFF position, then back to
the ON position.
WARNING: Never ride Lafree in the
Self-Diagnostic mode as it could cause
severe damage to the electronic
circuitry. Lafree’s power assisted pedal
and VPC Throttle will not work while in
the Self-Diagnostic mode.
7.5 Light Emitting Diode (LED)
Energy Level Indicator
Available energy is indicated via a Light
Emitting Diode (LED) string, located on the
top front of the motor housing. When fully
charged, all five LEDs will be illuminated.
LEDs will only illuminate when ignition is on.
As energy is used, fewer LEDs are
illuminated. When only one lit LED remains,
energy level is one percent. If energy level
drops below one percent, motor will
automatically shut down and one LED will
flash. If motor shuts off and single LED begins
flashing, turn ignition to OFF. Do not operate
electric functions until at least a 40 percent
charge (three LEDs illuminated) has been
attained. Charge time for this level is
depending on age of battery and how many
times battery has been charged/discharged.
See Section 6 for more information on battery
charging times.
