COMMON BIKE QUESTIONS
Q: Are the sounds my Bike makes normal?
A: Our Bikes are some of the quietest available because they use belt
drives and magnetic resistance. We use the highest grade European
bearings and top quality belts to minimize noise. However, because the
resistance system itself is so quiet, you will occasionally hear some slight
mechanical noises from the drive train. Unlike older, louder technologies,
there are no fans, friction belts, or alternator noises to mask these sounds
on our Bikes. These mechanical noises, which may or may not be
intermittent, are normal and are caused by the transfer of significant
amounts of energy to a rapidly spinning flywheel. All bearings, belts and
other rotating parts will generate some noise which will transmit through
the casing and frame. It is also normal for these sounds to change
slightly during a workout, and over time, because of thermal expansion of
the parts. Keep in mind that while you work out you’re sometimes
exerting the equivalent mechanical energy of a washing machine or dryer!
Q: Why is the Bike I had delivered louder than the one at the store?
A: All fitness products seem quieter in a large store showroom because
there is generally more background noise than in your home. Also, there
will be less reverberation on a carpeted concrete floor than on a wood
overlay floor. Sometimes a heavy rubber mat will help reduce
reverberation through the floor. And finally, if a fitness product is placed
close to a wall, there will be more reflected noise.
Q: When should I be worried about a noise?
A: As long as the sounds your Bike makes are no louder than a normal
conversational tone of voice, it is considered normal noise. If your Bike is
louder than this, you may want to call your service technician. Sometimes
an initial diagnosis can be made over the phone.
