GENERAL WARNINGS
Like any sport, cycling involves risk of injury and it is the rider’s responsibility to assume
potential risks and injury involved when riding. By choosing to ride a bicycle, you assume the
responsibility for that risk. You need to know and practice the rules and safety regulations of
riding this bicycle. Proper use and maintenance of your bicycle reduces risk of injury. Check
your local state or country regulations for electric bike laws. For example, check the minimum
age for using an electric bike as this differs in various regions.
Riders must have the physical condition, reaction time, and mental capability to ride and
manage traffic, road conditions, and sudden situations. Also, respect the laws governing
E-bike use in accordance with each region. If you have an impairment or disability (i.e. visual
impairment, hearing impairment, physical impairment, cognitive/language impairment, seizure
disorder, etc.), consult your physician before riding any bicycle.
• When riding, obey the same road laws as all other road vehicles, including giving right
of way to pedestrians and stopping at red lights and stop signs.
• For additional information, contact the road traffic authority, police department or
Department of Motor Vehicles in your state or country.
• Use correct hand signals to indicate turning or stopping.
• Concentrate on the path ahead. Avoid potholes, gravel, wet or oily roads, curbs,
trains, tracks, speed bumps, and other obstacles.
• Walk your bike across all train tracks.
• Expect the unexpected, such as opening car doors or cars backing out of driveways
• Be aware at intersections and when preparing to pass other vehicles or other
cyclists.
• Familiarize yourself with all the bike features. Practice using the brakes and throttle.
• If you are wearing loose pants, secure the bottom using leg clips or elastic bands to

SAFETY
The following safety notes provide additional information on the safe operation of your Super73
and should be closely reviewed. Failure to review these notes can lead to serious injury or
death.

19
1. BEFORE AND AFTER EACH RIDE
Check the alignment of the wheels.
Check the state of charge of the battery.
Check that brakes function properly.
Check tires for any punctures, and wheels for proper alignment.
Store the bike carefully in a clean and dry place.
Check that your kickstand is tightly secured.
Check for loose cables or wires that may be strained when turning the
front wheel from left to right.
2. EVERY MONTH
Inspect the handlebar and steer tube for any unusual movement.
Check the cables, tires, handles.
Check the wear of brake rotors, brake pads (see section on brakes), and
replace them if necessary.
Check the tension of the spokes, and ensure that the wheels are true and
properly dished.
Lube the chain and check the tension in the chain. It 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.
3. EVERY SIX MONTHS (depending on frequency and type of use)
Inspect the frame, fork and look for signs of cracks in the metal.
Check the bottom bracket and crankshaft and tighten the bolts on each
crank.
Check and grease the wheel hubs, headset, all parts in friction.
For your own safety, if any of the recommended maintenance procedures are not within
your skill set, we advise taking your Super73 to an E-bike specialist or professional cycle
mechanic for inspection.
!
DANGER!
Intensive use of the Super73 may cause possible damage to the frame and the fork. It is
important to inspect the frame and the fork and look for signs of cracks. A broken or
cracked frame and fork can cause an accident and injury. Refer to the Intended Use
section of this manual.
MAINTENANCE SCHEDULE
In order to prolong the life expectancy of your bike, here is an example of a maintenance
schedule, under intended use, that we recommend the following:
TIP
WASHING AND CARING FOR YOUR BIKE
Dirt, salt, and other elements can damage your bike. Regularly clean your Super73 and
protect it against corrosion. Use clear water for cleaning and a gentle soap if necessary
to dissolve grease and other residues. Do not spray water directly onto your Super73.
Instead, use a lightly damp cloth to wipe down any dirt or debris. After drying
your bike, treat surfaces with a care product. Finally, wipe all parts with a clean, soft
cloth.
Do not clean your Super73 with a strong water jet or steam jet from a short distance.
The water can get passed the seals and get inside the bearings. Lubricants are then di-
luted, increasing friction. In the long run, the bearing surfaces will deteriorate.

MAINTENANCE & COMPONENTS
Before performing any work on your Super73 electronics system, turn off the system.
Involuntary activation of the Super73 system poses a risk of injury.
The Z/ZG has tire sizes of 20” x 4.25” rubber tires with inner tubes and a rim liner.
The tube size for both the front and rear tires is 20” x 4.25” or 20” x 4”. 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 18 and 25 psi (1.24 - 1.72 bar). Check the condition of the tires and
rims for damage, cracks or deformation. The recommended tightening torque of the
wheel nuts is 25ft/lb (34 N m).
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.
!
DANGER!
TIRES / WHEELS
CHAIN TENSION
There should be approximately one half inch of movement in the chain up and down at a
point halfway between the front and rear sprockets. To change the tension loosen one
of the axle-nuts and move the wheel forward or backward to adjust and then tighten the
bolts when proper tension is achieved.
