MAINTENANCE & COMPONENTS
DANGER!
Before performing any work on your Super73 electronics system, turn off the
system and remove the battery. Involuntary activation of the Super73 system
poses a risk of injury.
TIRES / WHEELS
The ZX has tire sizes of 20” x 4.5” rubber tires with inner tubes and a rim liner. The
tube size for the tires is 20” x 4.5” The tires are designed for durability and safety
for regular cycling activities.
However, tires must be checked before each use for proper inflation and condition.
Proper inflation, good maintenance, and quick replacement will help ensure that the
operational characteristics of your bike will be maintained and dangerous conditions
avoided.
Tires must be inflated using a pump with a Schrader valve tip with a recommended
pressure between 20-25 psi (1.38-1.72 bar). Check the condition of the tires and rims
for damage, cracks or deformation.
The minimal tightening torque of the wheel nuts is 16ft/lb (21.69 Nm).
It is essential that the proper air pressure is maintained in the tires all the time. Do
not under-inflate or over-inflate your tires. Low pressure can cause loss of control
and tires that are too inflated can burst. Failure to maintain proper air pressure
rating indicated in the handbook may at any time result in tire and / or wheel failure.
Inflate your tires from a regulated air source with an available manometer. Inflating
your tires with an unregulated air source could over-inflate them, resulting in an
exploded tire. When tire wear becomes obvious or a hole in the tire is found, you
must replace the tires and / or tubes before using the bike, otherwise injury to
operators and / or damage to your bike could occur.
In addition to proper inflation, correct wheel alignment helps to decrease tire
wear. If you find a tire is worn unevenly, have a professional cycle mechanic
check the wheel alignment.
CHAIN TENSION (USA)
The ZX is equipped with a chain tensioner. It is recommended that you inspect the
chain tensioner for wear and periodically lube the chain to extend its service life. The
chain should be tight enough that it only allows you to move it up and down about
one inch. If it is sagging or much looser than that, you need to tighten the chain or
replace it.
To applybike chain lube, deposit a drop on the top of each link asyouslowly
backpedal for a few revolutions, so thelubehas a chance to work its way in. Wipe off
excesslube—ifyoudon’t, itcanattract more dirt to yourchain.Be careful to not get
lube in the brake calipers or pads.
