OPERATION INSTRUCTIONS
Exercise cycle 915E
This testing cycle is provided with a brake system, which
power can be read in watts at two different speeds, 24
km/h (60 rpm) and 28 km/h (70 rpm). See fig 8.
This model is also equipped with an electronic meter
which – on one big display – at the same time shows:
PULSE (heart rate), SPEED (km/h), TIMER, CALO-
RIES and DISTANCE (km). See more under Fitness
Computer.
When pedalling the test person supplies the flywheel
with a certain kinetic energy. This kinetic energy is
braked by means of a brake belt which runs around
the bigger part of the brake surface of the flywheel.
The brake power is changed either by using another
pedalling speed or by increasing or decreasing the ten-
sion of the brake belt against the flywheel by means of
the tension handwheel. See fig 8.
The height of the saddle is adjusted so that, when you
sit comfortably with your foot exactly above the pedal
axle and with the pedal in its down position, your knee
is only slightly bent.
The adjustment of the handlebar should give a com-
fortable ride. When cycling for a long time, it may be
suitable some time during the exercise to change the
position of the handlebar.

SETTING OF WORK LOAD
If you intend to exercise with a work load of 50 watts
and a pedalling speed of 24 km/h (60 rpm), do as fol-
lows:
Check on the RPM-display of the meter that you have
achieved the correct pedalling speed.
After that the tension handwheel should be adjusted
so that 50 watts are shown on the scale for 24 km/h.
Power conversion table at other pedalling speeds
The conversion table below shows the conversion into
watts at other pedalling speeds than 24 and 28 km/h
respectively. The result is achieved according to the fol-
lowing example:
Chose as work load any of the watt numbers on the
scale for 24 km/h at the same time as you pedal with
this speed.
Let us imagine that you have chosen 120 watts as work
load. If you now increase the pedalling speed to 90
rpm the table should be read as follows:
Start from the line 24 km/h and continue to 120 watt
and further to the line for 90 rpm. You can then read
that the actual power is 180 watts. See the markings in
the table below.

BRAKE BELT CONTACT SURFACE AND BRAKE BELT
Deposit of dirt on the brake belt and on the contact
surface may cause the unit to operate unevenly. The
brake belt contact of the flywheel surface should then
be ground off with a fine abrasive cloth, see fig 13, and
any dust be removed with a clean dry cloth
Remove the brake belt before the grinding. Grinding
off any build up of dust etc is easier if a second indivi-
dual cautiously pedals the cycle
Irregularities on the brake belt contact surface are also
removed by means of a fine abrasive paper or an abra-
sive cloth. Otherwise unnecessary wear on the brake
belt may occur and the unit can become noisy.
We recommend you to replace the brake belt when
cleaning the contact surface. See fig 14.
Always keep the brake belt contact surface clean and
dry.
REPLACEMENT OF BRAKE BELT
Loosen the screws (2 pcs) of the cover. See fig 14.
Remove the left chain cover as described on page 12.
Adjust the handwheel so that there is no tension in the
brake belt.
Loosen the screw underneath of the joint clamp. See
fig 14.
Loosen the screw for the fastening of the brake belt.
Replace the brake belt and assemble the other parts in
the reversed order according to the above.
Note! Too big a play in the bearing of the watt scale may
cause an uneven operation of the load device, The nut for
the bearing bolt should then be tightened. See fig 14. Make
sure that it is not tightened too much as it may then ope-
rate slowly.

CHAIN 1/2” X 1/8”
Fig 16
Fig 15
Fig 17
Check the lubrication and tension of the chain at re-
gular intervals.
In the middle of its free length the chain should have a
minimum of 10 mm of play. See fig 15. When the play
in the chain is about 25 mm (1 inch) the chain should
be tightened.
To change the tension of the chain the lower cover
bracket should be loosened by means of a screwdriver.
See fig 16. Remove the screw of the right and left co-
ver. Move the covers backwards, in order to remove
them. Loosen the axle nuts. The hub and axle are then
moved forward or backwards by loosening or tight-
ening the nuts of the chain tensioners. Then tighten
the nuts on the hub axle again. See fig 15.
Please note! The spring of the chain lock should be assem-
bled with the closed end in the movement direction of the
chain. Use a pair of tongs for dismantling and assembling
the spring. See fig 17.
When the chain has become so long that it can no
longer be tightened with the chain tensioners it is worn
out and should be replaced with a new one.
Please note! The wheel must be straightened parallel to
the center line of the frame. Otherwise the chain will get
caught on the tops of the sprocket and cause noise.

REPLACEMENT OF THE FREEWHEELING SPROCKET
Fig 20
Dismantle the covers and the chain. Loosen the axle
nuts as described on page 12.
Lift off the wheel and remove the axle nut, washer,
chain tensioner and spacer on the freewheel side.
Place the remover (our part no 9100-14) in the adap-
ter and place the spacer and axle nut outside. See fig
20 and 21.
Please note! Do not tighten the axle nut completely. It must
be possible to loosen the adapter–sprocket half a turn.
Replace sprocket–adapter and assemble the other parts
in reverse order according to above points.
The sprocket should be lubricated with a few drops of
oil once or twice a year. Tilt the cycle somewhat to
make it easier for the oil to reach the bearing. See fig
22.

General
It is important that you keep your exercise cycle clean
and properly lubricated. Periodically wipe the surface
with a rust preventive, especially when it has been cle-
aned and the surface is dry. Most important is to pro-
tect the chromed and zinced parts, but also painted
parts benefit from the same protection.
When cleaning and lubricating be sure to check that
all screws and nuts are properly tightened.
Please note: The production number of your exercise
cycle is placed according to fig 4, page 6.

THE IMPORTANCE OF REGULAR EXERCISE
The human body is built for action – not for rest. Once
upon a time this was a necessity: the struggle for survi-
val demanded good physical condition. But optimal
function can only be achieved by regularly exposing
the heart, circulation, muscles, tendons, skeleton and
nervous system to some loading, i.e. training.
In the old days the body got its exercise both in work
and at leisure. In our modern society, however, mach-
ines have taken over an ever increasing share of the
tasks which were formerly accomplished with muscu-
lar power alone. Our life has at an accelerated tempo
been dominated by sitting, riding and lying. Thus the
natural and vital stimulation that tissues and internal
organs receive through physical exercise has largely dis-
apperard. Certain tissues such as muscles, bone and
blood and also a number of bodily functions can adapt
to inactivity – and to stress. Studies have proved that if
you use 30 minutes for exercise like brisk walking, run-
ning, bicycling, swimming or skiing 2-3 times a week,
your condition has been improved by some 15 per cent
after a few months. The efficiency of the heart muscle
will increase and joints and muscles grow in strength.
The capillary density increases in the trained muscle
and their enzymatic activities are enhanced. The body
adapts to the new demands. The perceived exertion at
a given rate of exercise becomes reduced.
With increased physical activity fatness is counteracted,
the appetite functions ”safer”, you can eat more with-
out risk for overweight and thereby the risk of lack of
important essential food nutrients decreases. For many
individuals the effect of habitual physical activity also
improves the wellbeing and it is a good feeling to have
a potential to cope with straining situations.
What kind of exerciswe to choose?
1. You should have fun when exercising. Choose
something you find pleasure in doing regularly.
2. To get a good effect out of the training you should
choose a form of exercise that engages large muscle
groups. Then the demand of increased blood flow
and oxygen transport will be so great that heart will
increase its pump capacity. Jogging, calesthenics,
aerobic dancing, bicycling, swimming, skiing and
walking are excellent examples of exercises meeting
this requirement.
In a few months you can get 10-15 years younger
If you cycle 30 minutes a few times a week you can
lower your condition age with 10-15 years! Scientifi-
cally this is described as a reduction of the biological
age. Externally, you are your usual self. Internally, how-
ever, you feel much younger. In other words: You can
work harder. You fell more alert and healthy. Your ability
to handle stress and problems increases.
There are few better ways to improve you physical con-
dition than to cycle. It does not over-tax your joints. It
builds up your condition progressively and at your own
pace and – you make your training fit weather condi-
tions.
Do I loose weight when I cycle?
Yes! You do use calories. A few miles on your bike eve-
ry day over one year, you will have lost the equivalent
of 20 pounds of body fat. You will achieve best results
if you combine exercise with healthier eating. A little
less sugar, less butter on your bread or less fat in you
frying pan. An a few miles on your bike every day. In a
year you will have lost 20 pounds.
Do I get stronger?
Cycling strengthens the muscles of the back, abdomen
and legs. Daily chores become easier. Cycling also ma-
kes your heart stronger. Your pulse rate gets lower even
when you exert yourself a little extra. Regular exercise
also has a favourable influence on high blood pressu-
res.
How do I train?
Condition training:
1. Warm up 3-5 minutes with a low pedal resistance.
Pedal at about 12 mph (20 km/h).
2. Increase the resistance until you feel the training
”somewhat hard”. Keep the speed for 2-5 minutes.
Get off the exercise cycle and rest a few minutes.
Cycle again and then rest. Train at your own pace
and with a comfortable pedal resistance. After a few
weeks you can increase the resistance.
3. Before ending, pedal a few minutes with a light re-
sistance, in order to step down your training.
Strength training:
1. Give yourself a thorough warm-up.
2. Pedal with a heavy resistance for 5-10 seconds, then
rest 45-60 seconds. Repeat this 5-10 times.
Elderly people and physically weak persons should
consult a doctor before starting their training.
