M3i INDOOR GROUP CYCLE

04

It is the sole responsibility of the purchaser of Keiser Corporation 
equipment to instruct all individuals, whether they are the 
end user or supervising personnel, on proper usage of the 
equipment. Keiser Corporation recommends that all users of 
its equipment be informed of the following information prior 
to use.

1.         Read these instructions. Keep these instructions. 
2.  Heed all warnings. Follow all instructions. 
3.  Use the Keiser M3i Indoor Group Cycle (herein referred 

to as “bike”) for its intended purpose as described in this 

manual. Do no use attachments/accessories that have 
not been recommended by the manufacturer.

4. 

Maximum user weight limit: 350 lbs (159 kg). User height 
range: 58–84 inches (1,473–2,134 mm).

5.  Consult your physician before beginning any exercise 

program. 

6.  Heart rate monitoring systems may be inaccurate. Over-

exercising may result in serious injury or death. If you 
feel faint, stop exercising immediately and consult your 
physician.

7.  The bike is intended for use in training areas of 

organizations where access and control are specifically 

regulated by a person responsible for determining the 
suitability of use and maintenance. 

8.  Wear proper shoes. Dress shoes, sandals, slippers, or 

bare feet are not suitable for use on the bike. Quality 
athletic shoes are recommended for proper support 
and comfort. Do not wear clothing that might catch on 
any moving parts. Tie long hair back.

9.  Distractions, such as watching television, reading, using 

a computer device, or talking on the telephone while 
using the bike affect the ability of the user to safely 
exercise on the bike. Pay attention to and focus on your 
exercise while using the bike. 

10.  Routinely check and pay special attention to components 

most susceptible to wear. Refer to the “Preventative 

Maintenance Schedule” (page 22) for further instruction.

11.  Immediately replace damaged, worn, or broken parts and 

do not use the bike until all repairs have been completed 

and tested by a Keiser-certified technician.

 

12.  Only use replacement parts recommended by Keiser 

Corporation. Attempting to repair or replace any 
damaged, worn, or broken parts on your own is not 

recommended. A Keiser certified technician should be 

consulted.

13.  Proper posture and body position is necessary to achieve 

a safe, comfortable, and effective workout. Correct foot 
placement and arm reach must always be maintained 
during every workout. Refer to the sections under “How 

to Exercise on the Bike” (page 19) for further instruction 

and safety information.

14. 

The cycle is not designed with a freewheel, but a fixed 
gear system. When the flywheel is in motion, the pedals 

will also be in motion. For this reason, never remove your 

feet from the Pedals while the Flywheel is in motion as 
serious user injury may occur.

15.  Always secure your feet on the Pedals with the clip-in 

system or the Pedal Cage before your workout.

16.  It is recommended that the bike be pedaled in the forward 

direction.

17.  The Resistance Lever also functions as an Emergency 

Brake, allowing you to safely slow or stop the motion of 
the Flywheel. Move the Resistance Lever forward to slow 
the motion of the Flywheel. Move the Resistance Lever 
to the most forward position to engage the Emergency 
Brake.

18.  Do not make adjustments during exercise. Use the Pedals 

or the Resistance Lever to slowly bring the Flywheel to 
a controlled stop prior to making adjustments.

19.  Before dismounting the bike, push the Resistance Lever 

to the most forward position to engage the Emergency 
Brake. Wait until the Pedals come to a complete stop 
before dismounting.

20. Pedaling at high speeds or in the reverse direction  

or pedaling while standing are considered advanced 
techniques and should only be performed when the user 
has reached an advanced level or under supervision by 
a person that has reached an advanced level. 

21.  The bike is not a toy. Children shall not play with the 

bike. Children under 14 years old should not use the bike. 
Keep children and pets clear from the bike at all times, 
especially while in use. Cleaning and user maintenance 
shall not be performed by children. 

22.  The bike can be used by children age 14 years and above. 

Persons with mental disabilities, reduced physical, 
mental, or sensory capabilities, or lack of experience 
or knowledge should not use the bike without constant 
supervision by a spotter/supervisor.

23.  The bike should not be positioned in direct sunlight, in 

areas of extreme temperature and humidity, or where 

the bike may be splashed with water or fluids. The bike 

is intended for indoor use only.

24.  The minimum amount of free area around the bike is 

24 inches (610 mm) on all sides. Refer to the “Training 
Space” section (page 6) for further placement direction.

 

25.  The bike is suited for both home and commercial use. 

To ensure your safety and to help prevent damage to 
the bike, read all instructions before operating. Seek 
professional installation technicians if you are not able to 
safely perform the work necessary to unpack, assemble, 
and set the bike in a desired exercise location.

26. 

Failure to perform the “Proper Operation Check” (page 14) 

prior to normal use of the bike will void your warranty and 
could result in serious injury.

27.  The use of any exercise equipment, including, without 

limitation, Keiser’s strength training equipment in which 
resistance can be changed at anytime during the repetition, 

and any fixed gear bike, including, without limitation, the 

Keiser bike, without proper instruction and/or supervision
