1UNPACK
Open the packaging with caution. Unpack your Super73 over a large at clean area, with a
padded or soft surface like carpet to place bike parts without damaging them. Remove the
frame from its packaging. Stabilize the bike upright on the kickstand.
Do not sit on the bike with kickstand engaged.
DANGER! Please follow the instructions carefully to ensure the proper functioning of the
Super73. Failure to do so could result in serious personal injury and / or death.
2CHARGE THE BATTERY
1. Plug in the charger cable wall plug into a regular wall
outlet.
2. Then plug the charging cable to the battery port located
on the lower side of the seat.
3. Turn on the battery switch. Press the button, and the light
will come on. The button will stay pressed in.
We recommend charging the battery for 6-8 hours on the
rst charge. This will help condition the lithium-ion cells for
optimal performance.
When the charging process starts, the charger LEDs turns
red. Once the battery is charged, the LED turns green. Remove the charger cable from the
battery and then unplug it from the socket. Remember to put the protective cap back onto
the battery charging socket after charging to protect it from dirt and moisture.
Always make sure there is plenty of ventilation and a dry, reproof environment for the
charger and follow these operating instructions:
• Do not leave the battery connected to the active charger for more than 48 hours.
• Do not leave the charger connected to a socket for more than 48 hours.
• Charge the battery and use the bike at least once every 90 days
• Do not store the bike for more than 24 hours with an empty battery. This prevents a deep
discharge with irreparable consequences from occurring.
• Do not use the charger if the charger, main cable or connector cable have any visible signs
of damage.
• After being charged, if the battery remains connected to the charger, it will turn on and o
again in short spurts of green light. This is not a defect. It simply indicates that individual
battery cells are being slowly charged. Nevertheless, make sure that the battery is not
connected to the charger for more than 48 hours

ASSEMBLY IS FINISHED!
You’re almost ready to ride. Before each ride, it is important to do a full system check, such as
checking the tightness of all nuts and bolts. Make sure you follow every step in the next section
“Before the rst ride”.
BEFORE THE FIRST RIDE
If you have purchased your bike from a specialist dealer, they must provide the electric bike
in a condition ready to ride in order to ensure safe operation. The dealer must perform a nal
inspection and a test ride.
SAFETY CHECK
1. WHEELS
Check the tires’ condition, alignment and air pressure. Check the tires and wheels for damage,
cracks and deformation.
2. BRAKES SYSTEM
Pull both brake levers. You should feel an obvious pressure point and the levers should not be
able to touch the handle.
• Make sure that the disks are not rubbing against each other.
• If they do rub at the beginning, it’s normal because they are not broken in.
• To learn more about adjusting brakes go on our website, our YouTube channel, or visit your
local bike shop to have them professionally adjusted and tuned.
•
Check that the conguration of the brake lever matches what you are used to. Otherwise
your specialist dealer should adjust the conguration of the brake levers. More information on
brakes in our maintenance and components section on this manual.
3. CABLES: Look out for any loose cables
• Make sure the male and female plugs are properly connected.
• There should be no strain on any wiring near the fork when turing the handlebars from left
to right.
• Verify that the wiring on the frame is secure and free from any moving parts that may
damage the wiring. For example, the motor wire should be secure.
4. DISPLAY: Check that your display turns on and functions properly.
5. KICKSTAND: Make sure that the kick stand is tightly secured, and not rubbing against
the ground or tires. DO NOT SIT ON A BIKE WITH THE KICKSTAND ENGAGED.
!
DANGER!
Make sure the brakes have already been applied prior to getting on to your bike. If the assistance
mode is turned on, your E-Bike will start moving as soon as you push on the pedal. The unfamiliar
push can otherwise cause a fall, hazard, or accident.

THE FIRST RIDE
Riding off-road (sand, gravel, dirt, uneven terrain)
Please note that the Super73 is designed primarily for riding on at, paved roads. Riding on any other
surfaces including sand, grass, gravel, dirt, rocks, or various uneven terrain may signicantly decrease
battery life and motor performance.
Battery Range
Power output will vary depending on battery capacity. If your battery is at 20%, for example, it won’t have
as much power as a fully charged battery. If your Super73 has been shipped to you along with the battery,
please fully charge the battery rst. When a battery leaves the factory, it’s not fully charged as required by
air freight legislation. Battery is fully charged when the LED light on the charging cable converter is green.
More information on range and performance in the Maintenance and Components section of this manual.
DANGER!
If the user rides the Super73 in situations beyond its intended use, there may be a risk of an
accident, serious injury or death and the risk of injury to those around the user.
BRAKES
Your Super73-Z comes with mechanical disk brakes that are easily adjustable.
Go to www.super73.com/pages/owners for videos and tutorials on brake adjustment
DANGER!
Do not place any metal objects into the charging port as this can result in a short circuit and
render your battery non-chargeable and in need of replacement. This will void the warranty.

15
MAINTENANCE SCHEDULE
We recommend sourcing a local ebike specialist or professional cycle mechanic to perform basic
maintenence needs. In order to prolong the life expectancy of your bike, here is an example of a
maintenance schedule, in the case of regular use, that we recommend following:
1. Before & after each outing
- Check the brakes
- Check the tire pressure and any damage
- Check the alignment of the wheels
- Check that the battery is locked on the frame
- Store your bike carefully in a clean and dry place
- Check that your kickstand is tightly secured
- Check for loose wires
- Charge your battery
2. Every month
- Inspect the possible presence of play in the steering tube
- Check the cables, tires, handles
- Check the wear of discs, brake pads, replace them if necessary
- Check the sail of the wheels, the tension of the spokes
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 play of the bottom bracket.
- Check and grease the wheel hubs, headset, all parts in friction.
For a more ecient control, it is advisable to go to your authorized dealer, in order to make a
thorough check. For your own safety, take your E-Bike for its rst inspection with your specialist
dealer after 200 to 400 km (125 to 250 miles) or at the latest after three months.
WASHING AND CARING FOR YOUR BIKE
Sweat, dirt and salt from winter road maintenance or sea air can damage your bike. You should
therefore regularly clean your Super73 and protect it against corrosion. Use clear water for
cleaning and a little bit of soap if necessary to dissolve grease residues. Do not spray water
directly onto your Super73. Instead, use a lightly damp cloth to wipe down any down any dirt
or debris. After drying your bike, treat surfaces with a care product. Finally, wipe all parts with a
clean, soft cloth.
ATTENTION!
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 diluted, increasing friction.
In the long run, the bearing surfaces will deteriorate.
!
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 a fall, danger or accident.

16
GENERAL WARNINGS
Like any sport, cycling involves risk of injury and damage. 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 diers in various regions.
Riders must have the physical condition, reaction time and mental capability to ride
and manage trac, road conditions, and sudden situations. Also, respect the laws
governing E-bike use with accordance to 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.
NOTICE: It is recommended that users pay special attention to all of the general
operating rules below before operating their Super73 bike.
• When riding, obey the same road laws as all other road vehicles, including giving way to pedestrians
and stopping at red lights and stop signs.
• For additional information, contact the road trac 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, train tracks, speed
bumps, drain gates, 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 power system.
• If you are wearing loose pants, secure the bottom using leg clips or elastic bands to prevent them

MAINTENANCE & COMPONENTS
!
!
!
TIRES/WHEELS
The Super73 has 20’’x 4.25 ‘’ (51cm x10.7 cm) rubber tires with inner tubes and a tube liner. The
tires are designed for durability and safety for regular cycling activities. However, tires must be
checked before each use for proper ination and condition.
Proper ination, good maintenance and quick replacement will help ensure that the operational
characteristics of your bike will be maintained and dangerous conditions avoided.
Tubes are 20”x4”-1/4 but 2”0x4” also work.
Super73 recommends 20-25 PSI (1.37 and 1.7 bar) for street riding for the front and rear tires on
the Super73. The minimal tightening torque of the wheels is 25 ft/lb (33.89 N m).
It is essential that the proper air pressure is maintained in the tires all the time. Do not under-
inate or over-inate your tires. Low pressure can cause loss of control and tires that are too
inated can burst. Failure to maintain the air pressure rating indicated on the tires may at any time
result in tire and / or wheel failure.
Inate your tires from a regulated air source with an available manometer. Inating your tires with
an unregulated air source could over-inate 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.
To avoid serious injury, make sure all air pressure has been removed from the inner tube before
removing the tire from the rim.
In addition to proper ination, correct wheel alignment helps to decrease tire wear. If you nd a
tire is worn unevenly, have your dealer check the wheel alignment.
CHAIN TENSION
There should be approximately one half inch of movement in the chain up and down at a point half
way between the front and rear sprockets. To change the tension loosen one of the axle-nuts and
move the wheel forward or backward slightly and tighten it up again.
HELMETS / REFLECTORS
A properly tting ANSI or SNELL, (or CE if you are located in Europe), approved bicycle safety
helmet should be worn at all times when riding your bicycle, or recommended per your local
laws. Always wear a properly tted helmet which covers the forehead when riding a bicycle. Many
states require specic safety devices. It is your responsibility to familiarize yourself with the laws
of the state where you ride and to comply with all applicable laws, including properly equipping
yourself and your bike as the law requires.
Reectors are important safety devices which are designed as an integral part of your bicycle.
Federal regulations require every bicycle to be equipped with front, rear, wheel, and pedal
reectors. These reectors are designed to pick up and reect street-lights and car lights in a way
that helps you to be seen and recognized as a moving bicyclist.
Check reectors and their mounting brackets regularly to make sure they are clean, straight,
unbroken and securely mounted.
DANGER!
Before performing any work on your Super73 electronics system, turn o the system and remove
the battery. Involuntary activation of the Super73 system poses a risk of injury.

19
BRAKES
For optimum braking performance, Super73 bikes are equipped with Tektro mechanical or
hydraulic disc brakes. See video on our website on how to adjust: www.super73.com/pages/
owners or Tektro brake adjustment manuals on www.tektro.com. The Super73 bikes are
assembled as follows:
For North America: front brake = right lever, rear brake = left lever
For Global/EU: front brake = left lever, rear brake = right lever
Using the same disc, braking performance is similar between a mechanical or hydraulic disc
brake, but there are some dierences in operation:
The wear of the pads on a mechanical disc brake can be regulated by unscrewing the cable
tension knob. There is a complementary adjustment of the inner pad which can be tightened
closer or removed from the disc by screwing it in or out with a 5 mm Allen key.
To ensure maximum service life of the brake components, avoid contamination of the pads and
the disc by greasy substances.
Regularly check the condition of your cables, ducts or harness and the wear of your pads. Some
discs are only compatible with “resin” pads. Do not use a metal pad with discs marked “Resin”.
For better ergonomics and safety, we advise you to adjust the brake levers in a position that
places it as a natural extension of the user’s arms. If you have any questions or concerns, please
contact us or your local bike shop.
Break-in period: Disc brakes have a 30-40 miles break-in period to achieve optimal pad seating
and performance. Exercise caution for the rst 30-40 miles each time your replace the brake
pads. If you notice a squeal-like sound at the beginning, it’s normal. The brakes are naturally
adjusting. Depending on the frequency of use, you may need to replace the brake pads.
Replacing the pads
When pads are worn, make sure to adjust both clearances between the rotor and pad so that
they are equal to 0.3 mm. If only one side is adjusted it will cause braking failure.
1. Pads and pad holders are held in place by a 3 mm pad retainer bolt on the caliper. To remove
the pads and pad holder, unscrew the retainer bolt, then gently push out the pads and holder.
This may be easier to achieve by using the Allen wrench.
2. Once free of the caliper, the pads may be easily removed from the pad holder.
Warning
- Do not adjust the cable tension only to compensate pad wear.
- After you replace with new pads, check to see if the rotor and pads have contact with each
other. If so, go back to step 1 and 2 to adjust until a 0.3 mm clearance is visible.

BATTERY
The battery is the most important component on your Super73. Following a few simple rules, you can
optimize its life. Here are a few tips :
• Do not store a discharged battery. It could go into deep discharge which will reduce its life.
• Make it a habit to recharge at the end of each ride, so your bike will always be ready to go again.
• Even if it can withstand storage temperatures of 14°F to 104°F (-10°C to 40°C), you can optimize its
shelf life by storing it at room temperature 68°F (20°C).
• Observe operating conditions between 23°F to 104°F (-5°C to 40°C).
• Do not leave your battery exposed to high temperatures or direct sunlight for long periods of time
(for example, on the back of a car in direct sunlight).
• Please ensure that the contacts are always clean and do not insert metal objects.
• Do not dispose the battery in your trash. There are proper disposal methods for lithium-ion
batteries. Please check your local waste management regulations.
Warning: Lithium-ion battery transportation is subject to certain rules.
RANGE
The maximum range of a full charge depends on many variables such as: age of battery, type of
terrain and incline, rider weight, speed, outside temperature, driving style, amount of pedaling, or tire
ination.
Conditions that aect your battery’s range:
• Temperature: Extreme cold and heat can aect the batteries capacity.
• Total Number of Charge Cycles: As the battery ages, total capacity can decrease. The battery has a
total of 1000 full cycles when it’s new.
• Wind: Riding into a strong headwind can decrease range.
• Road Conditions: Excessively rough or hilly terrain requires the consumption of more power.
• Load: Carrying extra weight on the bike or in a backpack will use more energy.
• Operator Weight
• Repeated Acceleration from a standing start.
• Proper Gear Usage: Taking full advantage of the available gear will signicantly increase range.
• Poor Maintenance: Under inated tires, mis-adjusted brakes, a dry or dirty chain, can decrease
range.
Range in cold weather:
• In case of extreme cold, the range of your electric bike is reduced. It is a normal physical process,
and in no case a damage or defect of the battery. If you use your battery when temperatures rise,
its energy will increase again.
• We advise you to store the battery and charge it at room temperature during cold days and to use
your E-Bike immediately after installing the battery. The power consumption warms the battery
and you benet from a good battery life, even when it is cold outside.
• In winter however, plan for shorter trips or pedal with a lower level of assistance.
Tips for Maximizing Range:
• Charge the battery at room temperature (20°C, 3°-74°F)
• Lithium-ion batteries have no chemical memory, and it is not necessary to discharge the battery
completely for best performance. Charging a partially full battery will have no negative eects.
• Maintain proper tire pressures and lube the chain regularly.
• Operating temperatures between 4°C and 30°C (40°F and 85°F) will signicantly increase range.
• Get your bike a regular tune up (every 6 months) at your local bike dealer.
