Wheels, Tires And Tubes - ElliptiGO 8S Owner's Manual

Wheels, Tires and Tubes

Your ElliptiGO® bike comes equipped with a 20" spoked
wheelset, high-pressure clincher-style tires and presta-
valve tubes. These comprise the system that actually
connects the bike to the ground, so it is important that
you understand how they function and how to take care of
them.
Wheels
Your wheels are a critical part of your bike. You should pay
particularly close attention to the following parts of your
wheels:
True
To perform safely on the road, your wheels must
be "true." A wheel is true when all of the spokes
are tensioned such that there is no side to side
wobble when the wheel is rotated about the hub.
Truing a wheel requires special tools and skills
and should always be done by a trained bicycle
mechanic.
WARNING! A wheel that is not true can present a very
dangerous situation because it interferes with the proper
functioning of the brakes. It requires skill and proper
tools to correctly true a wheel. As a result, we strongly
recommend taking the ElliptiGO bike to a professional
bicycle mechanic to have your wheel trued prior to riding.
Riding on a wheel that is not true could cause you to lose
control and suffer a fall.
Rim Surface
Your rim should have no visible signs of wear and be
free from damage, including cracks, ruts or chips. To
check for wear, find the wear indicator groove on
the rim and ensure that it is still easy to feel depth
in the groove below the rim surface. If you cannot
locate the groove, DO NOT RIDE your bike. Instead
contact service@elliptigo.com or take your bike to
a certified bicycle mechanic.
WARNING! Never ride on a rim that is worn below the
wear indicator groove, a rim that is bowed, or a cracked
rim. Not only does a worn, bowed or cracked rim reduce
stopping power, but it will eventually break, likely without
warning. If your rim breaks it will almost certainly cause
the tire to come loose and the rider to suffer serious
injuries or death from a resulting fall.
Spokes
Each spoke plays a critical role in providing wheel
strength, performance and alignment. Loose spokes
and over-tightened spokes can both present dangers
to the rider. Ensuring that your spokes are in proper
tension requires special tools and skills and should
always be done by a trained bicycle mechanic.
