LC4 / LC4r

Thank you for choosing a test cycle from Monark!

Ideal position is important for a performance to reach its maximum and increases the potential for a perfect performance. The new setting options, along with an upgraded workload adjustment, make Monark's renowned bike even better.

LC4 has a brand new frame that is adjustable in all directions• LC4's new frame also means the Q-factor can be reduced, which increases the opportunities for •

a better workout experience LC4 gives the condition, the rest is up to the rider• LC4 is also prepared for additional equipment - channels behind the covers make it easy to install •

different equipment for different needs LC4 is a great bike as it is, with additional equipment, it can be even better• LC4 can be calibrated, both mechanically and electronically•

Force is a strong word which brings many associations. For us, force is interesting when it can be measured and calibrated. For a brake-force to be correct, regardless of the system, it must be calibrated and controlled. On LC4 the brake system and calibration have been updated so that it is safer and more accurate. LC4 has also a new and more powerful engine for faster workload control.

NOTE! Use of the product may involve considerable physical stress. It is therefore recommended that people who are not accustomed to cardiovascular exercise or who do not feel completely healthy, should consult a physician for advice.

Product Information

NOTE! Before you start using the bike - remember to remove the pendulum locking devices and protective tape on the ﬂywheel.

Serial number

The serial number is located on machine plate (4) according to Fig: Overview.

Power on crank or ywheel

Monark bikes measure the effect of the ﬂywheel, so it will be a friction of 6-8% if you measure the impact of the pedals (measure the effect of the crankshaft, the difference is 4-5 %). These percentages will be primarily due to friction in the chain, pedals and bearings.

LC4 is set to measure the workload at the ﬂywheel. The bike can be set to work with effect in the pedals / crankshaft (the cycle constant).

Initial operation

LC4 is mechanically calibrated in the factory. The user may wish to verify this by performing the mechanical calibration of the pendulum weight. See ‘Electronic calibration’.

Apply power to the test bike by ﬁrst connecting the cable from the power adaptor to the test bike at the power connector (14) at the right side of the bike, see Fig: Overview. Then plug the power adaptor into the wall outlet. Turn on the power switch (10) and a green LED (9) lights up.

The cable from the power adaptor can be locked with the clamp (15) which is placed below the power connection.

Perform the electrical calibration as speciﬁed in section ‘Calibration’. Test by pedalling the bike. If the bike is working properly, it is ready for use.

PC software

If you need a pc software to do exercise tests on the bike, our software is available for free download from our website: www.monarkexercise.se.

Calories

There have been different theories on how to calculate this, since it depends on several factors and this means that it can only be seen as an estimate.

As a standard calculation when we display calories on our calibrated bikes we use: 1 minute with 100W gives 7 kcal. It is easy to convert watts to calories if it was on the ﬂywheel, the formula is 1W=0,2388x10

-3

kcal/s with four decimals. But when you normally show calories you want to show the total amount of calories your body has used during your training, not only the calories "burnt" on the ﬂywheel.

We have chosen the formula given above that we think complies with the results given for a standard cycle position.

Cycle adjustments

Seat height should be adjusted to a comfortable position. The appropriate height is to have the knee slightly bent when the sole of the foot is centred over the pedal axle with the pedal in the bottom position. When adjusting the saddle height and vertical position, loosen the respective locking handles. See Fig: Saddle

adjustment.

The handlebar setting should be in a comfortable position when cycling. During longer exercise sessions it is recommended to occasionally change handlebar position. The handlebar can be adjusted both horizontally and vertically. This is done by loosening the respective locking handles. See Fig: Handlebar

adjustment.

NOTE! Be sure that the stem and seat post are inserted to at least 100 mm in the frame. This is marked with “MAX” on the stem.

Validation

Fig: Saddle adjustment

Fig: Handlebar adjustment

The following procedure ensures that the bike works for daily use.

Check the HR function if you use chest belt, see • section, on 'Heart rate'.

Check the braking force by putting on a certain • workload and check that the load is applied.

Test by pedalling and check that a reasonable • rpm is obtained - verify by a clock. Feel if the pedals move smoothly. Listen for unusual sounds. Remedy if necessary.

Adjust the handlebar and saddle and make sure • they are securely attached and that the adjustment is working properly.

Make sure the support legs are in position by • rocking the bike. Tighten if necessary.

If something unusual is found during the daily inspection that you cannot resolve, please call customer service.

Garmin

LC4 / LC4r

The user's heart rate can be measured with a chest belt that senses the electronic output of the heart. Chest belt ANT+ is supplied as standard.

Fuss-free HR measurement requires that the belt is correctly placed. Make sure that your skin is clean where the chest belt should be placed. When it is correctly ﬁtted the logo on the belt will be central and readable, outward and upright, by another person. The chest belt should be placed with a comfortable tension around the mid section of the chest, just below the breast muscle, see Fig: Placement chest belt. Moisten the electrodes before use, see Fig: Moistening

the electrodes.

NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test.

Pulse standard (chest belts)

The following pulse standard / chest belts can be used:

Standard, uncoded 5K chest belts (5-5.6 kHz)• Chest belts with ANT+•

Short range ANT+: 0.6-0.8 m (24"-31 ½") Long range ANT+: 4-5 m (13-16 ft) Range 5K: 0.8 m (31 ½")

Pairing display and chest belt

Normally the display connects to the ﬁrst ANT+ chest belt in "short range" and shows the heart rate until the chest belt is outside the "long range". If there is no ANT+ chest belt but a 5K chest belt in "short range", the heart rate from the 5K chest belt is displayed until the signal is lost.

ANT+ is prioritized and the ﬁrst choice of the display. 5K is discriminated, but after 30 seconds with only 5K the display is locked to this chest belt as long as you do not lose the signal.

Pulse function

Monark Exercise AB recommend that you

use an ANT+ chest belt for best function.

We recommend to use only the AC adaptor when using the bike. Without the AC adaptor, there will be no workload control and display alarm is activated.

Calibration and basic settings are saved even when the power fails.

(The display can be powered by batteries, 4x1.5V, R14, but only when you make the basic settings.)

If the values for rpm and watt start ﬂashing during use, the set workload requires higher brake power than 7 kp. To solve this, increase the rpm or decrease the set workload.

Alternative power / force display

The meter displays power in watts (default). If you want to display the power in kpm / min instead, press the HEART button for 5 seconds. Then you can switch between WATT, KPM / MIN and current kpvalue using the (+/-) button. Press ENTER or wait 10 seconds to conﬁrm and exit the setting.

NOTE! Even if you select kp as unit, it is the power in watts

which is set in the background when you press (+/-) button.

The displayed kpm / min is a simpliﬁed calculation (1 kp = 10 N) according to Astrand's tables.

(Although the displayed kp value is correct and not rounded as above. For all calculations in the display the exact value is used, 1 kp = 9.80665 N)

Cycle constant

The cycle constant is as default set to 1.00. Change using the (+/-) button.

When the cycle constant is set to 1.00 the power is measured at the ﬂywheel. This is used in Astrand test, YMCA etc.

When the cycle constant is set to 1.05 the power is measured at the crank. This is often used on electronically-braked bikes.

Metronome cadence

Metronome diodes show pedalling revolutions (rpm) relative to the set reference value. The metronome is located at the back of the meter. The default value is 60 and can be adjusted with (+/-) button. The green LED in the middle ﬂashes twice for each pedal revolution which helps to keep the right pedal cadence, see Fig: Display and Fig: Metronome.

The meter can be rotated so that the rider does not see the values in the display, but only sees the ﬂashing diodes (in order to keep the right pedal cadence).

If START STOP is pressed, or if no button is pressed for 20 seconds (in all steps), the changes are saved and the display returns to normal with the new settings active.
