Bike Fitting - Keiser m3 User Manual

• The resistance shifter allows you to safely slow or stop the motion of the flywheel. Move the
resistance shifter away from you to increase the gear and slow the motion of the flywheel. This
method can also be used as an emergency operation to stop the motion of the flywheel. To use the
resistance shifter as an emergency brake, move the lever all the way forward to stop all motion within one
revolution. With any braking procedure, wait until the pedals and flywheel come to a complete stop
before dismounting.
• The Keiser M3/M3 + is intended for cardiovascular fitness training. Consult a qualified physician or
fitness professional to determine an appropriate training routine and determine if cardiovascular training
should be a part of your exercise program. Serious injury or death can occur from over-training and
should be taken very seriously.
• The Keiser M3/M3 + is to be operated in a commercial fitness environment, all use should be
supervised by a qualified fitness professional.
• Keep children and pets clear from the unit at all times, especially while in use.
• The Keiser M3/M3 + should be positioned on a stable, level, horizontal surface with a recommended
clearance of 18-24"/45-60cm on all sides.
• Movements such as pedaling at high speeds or pedaling while standing are considered advanced
techniques, and should only be performed when the rider has reached an advanced level and has
practiced basic cycling and pedaling techniques at slow to normal speeds.
• Ensure that all adjustment handles that could interfere with the user's movement are not left
projecting as to come in contact with the rider during operation.
• Before dismounting, push the resistance lever to the most forward position to bring both the
flywheel and pedals to a complete stop. Loosen each pedal clip strap, remove your feet from the
pedals and dismount the bike.

WARNING: Maximum weight of the rider shall not exceed 300lbs / 136kg.
SEAT POST HEIGHT POSITIONING
• Stand beside the cycle, close to and beside the saddle.
• Position the seat so that the top of the saddle is level with your iliac crest (hip), then
re-tighten the T-Handle after adjustment.
• Sit on the saddle with the balls of each foot over the center of the pedals, with your
toes in the pedal cage.
• Begin to pedal very slowly. There should be a 5-15 degree bend in the knee as it
extends down into the six o'clock position.
WARNING: If your hips are rocking back and forth in the saddle with each pedal
stroke, the seat position may be too high. Uneven rocking from side to side may
result in hip or back injuries.
WARNING: If a participant's knees are bowed outward (beyond their normal ergonomic
position), the seat may be too low. If the knees are too flexed, unwanted stress is placed
on the knee caps. The knee should never be in a locked-out (overextended) position.
