Transport

To position the bike at the desired location:

1. Grasp the Handlebar with both hands.
2. Tilt the bike toward you until the Transport Wheels contact the floor.
3. Roll the bike to the desired location; tilt it slowly away from you to set down.

Base Stabilizer

The bike must be placed on a flat, level surface. If the sub-floor is not level, the Base Stabilizer allows for stabilization.

To stabilize the bike:

1. Hold the Seat steady, then with your foot, swipe the Base Stabilizer counter-clockwise to drive it back into the base. This will un-stabilize the bike.
2. Slightly push across the Seat, until the Base Feet at all three corners contact the floor, then hold.
3. With the three Base Feet making contact with the floor, swipe the Base Stabilizer clockwise with your foot until the Base Stabilizer makes contact with the floor. This will stabilize the bike.

Test for stability. The bike should sit flat without rocking. Adjust and fine-tune the Base Stabilizer as needed. The bike should not be used until it is stabilized. If the bike is moved to a different location, adjust the Base Stabilizer as needed to stabilize the bike.

Resistance Lever

Resistance is controlled by the Resistance Lever, which can be set to any gear from 1 to 24. The higher the gear number setting, the greater the resistance.

Emergency Brake

Move the Resistance Lever to the most forward position to engage the Emergency Brake. This will stop the motion of the Flywheel within one revolution. Wait until the Pedals come to a complete stop before dismounting.

Seat/Handlebar Height Adjustment Knob

Set the Seat height to align with the top of your hip when standing beside the bike. The Handlebar Height Adjustment Knob operates in the same manner; handlebar height set at, or slightly above, the Seat height is recommended.

⚠️ CAUTION: Do not exceed maximum Seat height adjustment mark "STOP." Tighten all adjustment knobs before bike use.

Seat Depth Adjustment L-Handle

Set the Seat depth (horizontal adjustment) to where the distance between the Seat and Resistance Lever is approximately the same distance between your elbow and fingertips.

Pedal Cage Strap Adjustment

Always secure your feet onto the Pedals using the Pedal Cage before your workout. Place the widest part of foot over the Pedal. Pull up on the Pedal Strap to tighten the Pedal Cage, snug to fit. After workout, push down on the buckle to release the Pedal Strap tension. For cycling shoes, clip cleats at the opposing side of the Pedal Cage. The bike is not designed with a freewheel, but a fixed gear system. When the Flywheel is in motion, the Pedals will also be in motion. Stop by reducing pedaling frequency in a controlled manner or by using the Emergency Brake.

Computer Display

Overview

The computer display provides the following information:

• 1 BACKLIGHT SENSOR: While the computer is awake, the backlight sensor automatically detects ambient light levels in the room and turns on the backlight display when needed.
• 2 RPM (CADENCE): The RPM displays the revolutions per minute of the crank arm, also known as cadence, and is roughly the speed at which the cyclist is pedaling.
• 3 POWER AND ENERGY: The power output is displayed in Watts (currently generating) and Kilocalories (total value for the workout). The computer toggles between Watts for eight seconds and Kilocalories for two seconds. Accuracy for power between 30 and 160 RPM is ±5 Watts for power below 50 Watts, and ±10% for power above 50 Watts.
• 4 HEART RATE: If there is no Heart Rate signal, a steady heart symbol and zero will display. If a user is wearing a Heart Rate strap, the heart symbol will blink and display the heart rate. Compatible Heart Rate Sensors: POLAR® H9, POLAR® H10, or similar devices.
• 5 ELAPSED TIME: Reports total workout time spent and resets to zero after 60 seconds of inactivity or if the computer is reset using the gear shifter.
• 6 GEAR: Gears from 1 to 24 are displayed on the bottom left hand of the screen.
• 7 ODOMETER/TRIP DISTANCE: When activated, the Odometer "ODO" displays distance accrual for the first eight seconds (for service/maintenance). After eight seconds, it displays Trip units for two seconds, then Trip Distance for the remainder of the workout. Trip is a calculated distance value based on power production.

Display Features

Workout Data

To view RPM, Power, and Heart Rate averages, stop pedaling for three seconds. Averages will flash until you start pedaling again or the computer goes to sleep after 60 seconds. To reset all workout data during your workout: Stop pedaling for three seconds, then move the Resistance Lever up/down quickly two times to reset all workout data to zero.

How to Exercise on the Bike

Ride Set Up

Set the three points of contact on the bike to support proper body positioning:

1. SEAT: Set the Seat height to align with the top of your hip when standing beside the bike.
2. HANDLEBAR: Set the Handlebar height at, or slightly above, Seat height.
3. PEDALS: Place the widest part of the foot on the Pedal, or clip in with cycling shoe cleats (SPD). Set the Resistance Lever to a lighter gear and begin pedaling. Slow or stop pedaling and check your ride set up:
   • Knee: A slight knee bend must be present when the foot is at the lowest position. The knee must not be locked (i.e., the seat is too high) or have too much flexion (i.e., the seat is too low).
   • Seat Depth: The front of the knee should be in line with the widest part of the foot when the Pedal is positioned at three o'clock (away from Flywheel). Check for a slight bend at the elbows, neutral spine position, and shoulder blades drawn back and down.

Get off the bike before you make any adjustments.

⚠️ CAUTION: Ensure ride set up supports proper body positioning and all adjustments are secure before your ride. Be sure to stretch and warm up prior to your ride to help avoid injury. Add time to cool down and stretch after your ride to reduce stiffness/soreness. Failure to follow this instruction may result in injury.

Start Your Exercise

1. Set the Resistance Lever down and set the Pedal that corresponds to your leading leg pointing forward.
2. Clip in, or step in, to the Pedal with your leading leg, followed by your trailing leg to mount the bike.
3. Check that the cleats are properly secured to the Pedals, or pull up on the Pedal Strap to tighten the Pedal Cage (snug to fit), before you start your exercise.

End Your Exercise

1. Bring the Flywheel to a complete stop using the Pedals or the Resistance Lever/Emergency Brake.
2. Kick your heel away from the bike to clip out. Pedal Cage Riders: push down on the buckles to release the Pedal Strap tension.
3. Step off of the higher Pedal first, then the lower one, to dismount.

⚠️ WARNING: To prevent injury, always wait until the Flywheel comes to a complete stop before you attempt to dismount the bike.

Posture

As in any activity, proper posture is important. The preferred riding posture is to:

• Maintain a neutral spine and slightly hinge forward from the hips.
• Keep a natural curve in the low back.
• Activate the core (midsection; deep abdominal muscles).
• Open up across the collarbones.
• Draw the shoulder blades back and down.
• Keep the elbows slightly bent when the hands are placed on the handlebar.
• Maintain good lower body alignment from the hip to the knee, down to the second toe.

Ride Positions

Observe the following suggested ride and hand positions for your desired workout. Include a variety of hand positions in combination with the cycling postures to add variety and to help prevent wrist and hand discomfort. Maintain proper ride positioning with control of both the upper and lower body for optimal cycling experience.

Basic (Cadence: 60-110 RPM)

Distribute body weight evenly between the Seat, Handlebar, and Pedals. The basic posture serves as a point of reference for all other riding positions. Keep your upper body relaxed with your shoulder girdle and neck in neutral alignment. Engage the core (midsection, deep abdominal muscles) with the pelvis in a neutral position. Knees are parallel and in line with the second toe. Avoid seat discomfort by ensuring your glutes shift back into the seat. Fine-tune the Seat or Handlebar settings for comfort and to support the basic ride position.

Seated Climb (Cadence: 60-90 RPM)

Add moderate to heavy resistance to simulate a hill climb. This naturally shifts the rider slightly towards the back of the seat. Focus on maintaining a steady cadence; avoid side-to-side body rocking by keeping even pedal strokes. The upper body remains relaxed; keep core engaged. Keep a light grip on the handlebar; hand position 1 or 2 complements the seated climb.

Standing Climb (Cadence: 60-90 RPM | Heavy 60-75 RPM | Faster 75-90 RPM)

Gear up to a higher resistance and transition to a standing position. There is a natural and slight body sway to create momentum and to power each pedal stroke. Keep each pedal stroke smooth and fluid. The center of gravity is low in the body with very minimal body weight on the handlebar; hand position 2 or 3 complement the standing climb. A cadence of 60-90 RPM is recommended for climbing; varying from heavy to light resistance. Heavy climbs: shift weight back, RPM from 60-75. Faster climbs: shift weight slightly forward and over the middle of the seat at 75-90 RPM.

Lifts (Cadence: 70-90 RPM)

Lifts are advanced postures. Riders will alternate from seated to standing positions at the desired pace. Goal: take full advantage of body weight and strength. The resistance is moderate to heavy, and the lift or "attack" is short. Riders should lift the glutes back off the seat versus straight up, keeping the center of gravity low and back. No weight should be on the Handlebar; elbows in front of shoulders. Hand position 2 or 3 complements the lift.

Time Trialing (Cadence: 90-100 RPM)

The time-trialing posture allows cyclists to ride slightly faster. The rider's body is low and in a neutral position with body weight shifted slightly forward. The shoulder girdle and neck are in neutral alignment. Riders should shift slightly forward in the seat. Hand position 4 complements the time trial; keep the elbows raised slightly off the handlebar.

Pedaling

Pedaling utilizes a series of muscle contractions and relaxations that must be coordinated and synchronized. Pedal at an even, steady pace. Be sure to recruit all of the lower body muscles at every phase of the pedal stroke for an effective workout.

Cadence (RPM): Slow (60-80), Moderate (80-100), Fast (100-110).

Gear Ranges: Introduction (1-5), Warm Up (5-10), Easy Flat (8-12), Hard Flat (10-14), Easy Climb (12-16), Hard Climb (14-18), Very Hard Climb (16-24).

Gear ranges are suggested settings to help riders meet their training goals. Instructors may use gear ranges to help direct and coach riders of varied abilities. It is important that the individual rider establish gears based on their current fitness level, goals, and ability.

Maintenance

⚠️ CAUTION: Routine maintenance is an essential part of maintaining the highest level of equipment safety, as well as optimal equipment performance. Immediately replace damaged, worn, or broken parts and do not use the bike until all repairs have been completed and tested by a certified Keiser technician.

Preventative Maintenance Schedule

• Every Workout: Bike is properly stabilized, level to the floor (refer to "Base Stabilizer" section, page 15). Check that parts most susceptible to wear are not damaged or broken (Adjustment Knobs, L-Handle, Pedal Cages, Pedal Straps, and Seat Upholstery). Cleaning: Target areas in the sweat path with a dry soft towel or cloth.
• Weekly (for the 1st Month): Check to ensure that the bike is in safe proper working order (perform the full "Proper Operation Check," page 13). Check that parts most susceptible to wear are not damaged or broken (Adjustment Knobs, L-Handle, Pedal Cages, Pedal Straps, and Seat Upholstery).
• Monthly: Clean the external body/parts thoroughly, targeting areas that come in contact with sweat, using a damp soft towel and a mild detergent (neutral, non-caustic). Wipe dry the equipment.
• Quarterly: Apply wax to protect the paint finish on metal parts: 1. Wipe down and thoroughly clean the bike prior to applying wax. 2. Use an easily applied automotive treatment such as Meguiar's® Quik Detailer Mist and Wipe. 3. Target areas that come in contact with sweat as they are most vulnerable to rust. NOTE: Failure to apply a coat of wax to high-sweat areas at a minimum of four times a year will decrease paint and frame life due to corrosion and will void the warranty.
• Annually: Check to ensure all external visible screws and nuts are not loose and that they are tightened. Check parts most susceptible to wear and replace if damaged or broken (Adjustment Knobs, L-Handle, Pedal Cages, Pedal Straps, and Seat Upholstery). The low battery signal ("LO-BA") will appear on the computer display when it is time to replace the batteries (two AA batteries, refer to "Computer Battery Replacement" on page 23 for complete instructions). NOTE: For establishments with multiple bikes, replacement of all computer batteries at the same time is recommended. Apply LPS 3® Rust Inhibitor or WD-40 Specialist® Corrosion Inhibitor to the Left Bottom Bracket Bearing and to the clip-in portion of each Pedal. Apply lubricant to the Adjustment Knobs: 1. Unscrew and remove the Adjustment Knobs. 2. Clean threads with a lint-free cloth. 3. Apply a moderate amount of lubricant to threads, then replace the Adjustment Knobs. NOTE: Both the threaded stud and the threaded insert nut are stainless steel. It is critical to keep the threads lubricated with a heavy grease (preferably white or clear in color), such as HYDROTEX® Acculube #2 or any compound with equivalent anti-wear and corrosion resistant properties.

Computer Battery Replacement

Do not operate the equipment during battery replacement procedure. "LO-BA" will appear on the computer to indicate that the batteries are low and need replacement. If batteries are dead (depleted), the Computer Display remains blank. To replace the batteries, refer to Figure 23 and follow the instructions below (Tool required: #1 Phillips screwdriver).

1. Remove the screw that secures the Computer Display to the Display Mount (remove Media Tray, if equipped, for easy access the screw).
2. Remove the two AA batteries.
3. Install two new AA batteries, observe the correct polarity (see +/- marking inside the battery compartment). NOTE: R6 (Zinc-Carbon) or LR6 (Alkaline) type batteries are acceptable. Do not use FR6 (Lithium) or similar type batteries.
4. Tuck the Computer Wire back into the Mount as you slide the Computer Display up and onto the Display Mount, then reinstall the screw removed in Step 1.

Immediately after battery replacement, the Computer Display enters a diagnostic mode for approximately 1 minute (system data readout, followed by a series of flashing numbers). After the diagnostic mode, the Computer Display will enter sleep mode (blank screen), and the cycle is ready for use.
