ASSEMBLY INSTRUCTIONS

Do NOT ride your SUPER73 if it has been assembled incorrectly. Riding an incorrectly assembled e-bike will give rise to a risk of injury, death and/or property damage. Before you ride your e-bike (including before the first use and before all subsequent uses), perform the Pre-ride Safety Check.

HANDLEBAR INSTALLATION

1. Use the 5 mm hex wrench to remove the bolts from the handlebar clamp.
2. Once the clamp is open, place the lower crossbar of the handlebar in the groove of the top crown.
3. Loosely tighten the handlebar clamp with the 5 mm hex wrench, and adjust the angle of the handlebar to the rider's comfort.
4. Cross-tighten the handlebar clamp from corner-to-corner making sure the clamp is tight and the handlebars do not move.

INSTALL PEDALS

1. Install and tighten the pedals using the 15 mm open wrench. Look for a letter marking "L" or "R" on each respective pedal and make sure to install the left pedal on the left crank, and the right pedal on the right crank.
2. The right pedal is screwed on in a clockwise direction. The left pedal is screwed on by turning it counter-clockwise.

TIRE INFLATION

For transport purposes, tires are packed partially inflated. Tires must be inflated using a pump with a Schrader valve tip to a recommended 20-25 psi (1.38-1.72 bar).

1. Inflate the tube to a max pressure of 35 psi in order to ensure that the tire is properly seated in the rim.
2. Once properly seated, deflate the tube to a recommended 20-25 psi (1.38-1.72 bar). PSI will vary based on the weight of the rider and the type of terrain.

The inner tube size is 20" x 4.5" for the rear and the front tire.

REAR DERAILLEUR AND GEARING

Make sure to check that your chain and derailleur are properly aligned by looking at the derailleur from the rear.

1. The two pulleys should be lined up exactly underneath one another, so that the chain runs straight up from the tension pulley to the jockey pulley, with no sideways slant.
2. Compare the line of the pulleys with that of the sprockets above them.

CHARGE THE BATTERY

We recommend charging the battery for 6-8 hours on the first charge. This will help condition the lithium-ion cells for optimal performance.

The battery can be charged both mounted on the bike or separately from the bike. Two keys are supplied to unlock and lock the battery.

1. Plug the charger into a 220v EU wall outlet.
2. Connect the charger cable to the battery charging port. Make sure to properly align the charge cable to the charging port.
3. Turn the battery on by pressing the power button. The power button will illuminate when pressed to indicate it is on. The battery will not charge unless it is switched on.
4. If you have a throttle, it is disabled during the charge sequence and a charge icon will appear on the display during the charging process.

When the charging process starts, the charger LED turns red. Once the battery is charged, the LED turns green.

1. Turn the battery off.
2. Remove the charger cable from the battery charging port.
3. Remember to put the protective cap back onto the battery charging port after charging to protect it from dirt and moisture.
4. Unplug the charger from the socket.

Always make sure that there is plenty of ventilation and a dry, fireproof environment for the charger, including before and after connecting the charger.

In addition:

• Do not leave the battery connected to the active charger for more than 10 hours.
• Do not leave the charger connected to a socket for more than 24 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 has any visible signs of damage, or if you are aware that they have been damaged.
• After being charged, if the battery remains connected to the charger, it will turn on and off 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 10 hours.

More information on range and battery care can be found in the Maintenance and Components section of this handbook.

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 first. When a battery leaves the factory, it's not fully charged as required by international air and sea legislation.

The battery is fully charged when the LED light on the charger is green.

SUSPENSION ADJUSTMENT GUIDE

The S2 defaults to a baseline setting. Follow the guides below to adjust the suspension to your desired comfort level. The S2 is equipped with an inverted coil-spring fork with air assist and the ability to adjust lockout and rebound damping.

FRONT SUSPENSION ADJUSTMENTS

Adjusting Air Assist Pressure
Adjustment of air assist pressure will require a shock pump. Use Figure 1 "suggested starting air pressure" to find your recommended air pressure.

• Remove the valve cap on the top left stanchion and connect your shock pump to the pressure valve.
• Review the current air pressure and adjust according to Figure 1. finetune the pressure with the shock pump to your desired comfort.
• Be sure you remove the shock pump in between adjustments as leaving it on can affect the active pressure in the suspension. After completing adjustment, reinstall the pressure valve cap.

Measuring Sag
The recommended sag of the front fork is 20mm into the travel, which can be measured with the bumper found on the lower portion of the right stanchion. To measure sag, place your bike somewhere level where you can safely put your full weight on the bike while balanced. It is recommended to have a friend help balance the bike during this portion of adjustment.

• Slide the bumper all the way down to the top of the air chamber. Then seat yourself on the bike, engage the brakes, and move into an aggressive standing position with your feet on the pedals.
• Dismount from the bike and measure the amount of travel between the bumper and the air chamber. If the measurement is more or less than 20mm, adjust the air assist pressure appropriately.

Adjusting Lockout
Lockout is adjusted with the dial on the top right stanchion.

• Turning the preload dial clockwise (+) will decrease compression on the suspension.
• Turning the dial counterclockwise (-) will increase compression on the suspension.

Adjusting Rebound

Rebound is adjusted with the dial located on the bottom of the right stanchion.

• Turn the rebound dial clockwise to slow your suspension rebound (damper increase).
• Turn the rebound dial counterclockwise to speed up the rebound (damper decrease).

We recommend keeping the air pressure between 70 PSI - 130PSI.

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 comply with 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.

MAINTENANCE SCHEDULE

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.

In order to prolong the life expectancy of your bike, here is an example of a maintenance schedule, under intended use, that we recommend. It is important to note that component wear is primarily caused by the distance over which the bike is ridden. As such, these time periods are indicative only, and will vary depending on the frequency of the use of the bike:

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.
• 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.
• Inspect all hardware to ensure it is properly tightened.

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, 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.
• Inspect suspension components for wear and make any necessary adjustments.
• Inspect all hardware to ensure it is properly tightened.

3. EVERY SIX MONTHS (depending on frequency and type of use)

• ‡ Inspect the frame and 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. ‡
• Grease suspension components and tighten hardware.

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.

Do not continue to ride your SUPER73 if any failure of hardware including bolts and fasteners integral to the brake system or wheel assembly should occur. Riding your SUPER73 with failed or missing hardware may put you at risk for potential injury or death.

MAINTENANCE & COMPONENTS

Before performing any work on your SUPER73 electronics system, turn off the system and remove the battery. Involuntary activation of the SUPER73 system will give rise to a risk of injury, death and/or property damage.

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, and take particular care not to spray water on or near the battery. This can damage the battery and create a risk of fire. In addition, the water can get past the seals and get inside the bearings. Lubricants are then diluted, increasing friction. In the long run, the bearing surfaces will deteriorate.

TIRES / WHEELS

The SUPER73-S2 has tire sizes of 20"x4.5" in the front and 20"x5" in the rear with inner tubes and a rim liner. The inner tube size for the tires is 20"x4.5" or 20"x5".

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 e-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 1.38-1.72 bar (20-25 psi) dependent on the weight of the rider and the type of terrain. Check the condition of the tires and rims for damage, cracks or deformation. The minimal tightening torque of the wheel nuts is 21.69 Nm (16ft/lb).

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 e-bike, otherwise, serious 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 that is worn unevenly, have a professional cycle mechanic check the wheel alignment.

HELMETS / REFLECTORS

A properly fitting 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 fitted helmet that covers the forehead when riding a bicycle. Further, local requirements may require specific safety devices. It is your responsibility to familiarize yourself with the laws of the country/state where you ride and to comply with all applicable laws, including properly equipping yourself and your bike as the law requires.

Reflectors are important safety devices that are designed as an integral part of your bicycle. Certain regulations require every bicycle to be equipped with front, rear, wheel, and pedal reflectors. These reflectors are designed to pick up and reflect street-lights and car lights in a way that helps you to be seen and recognized as a moving bicyclist. Check reflectors and their mounting brackets regularly to make sure they are clean, straight, unbroken, and securely mounted.

BRAKES

Brakes are an integral part of the operation of your e-bike and must be properly maintained, adjusted, and replaced when necessary. If any of these tasks are not within your skill set, we recommend taking your SUPER73 to an e-bike specialist or professional cycle mechanic.

The hydraulic brake system requires proper maintenance to be performed on the pads, rotors, and also on the hydraulic brake line. Always verify that your brakes are in good condition in order to maintain safe riding.

For optimum braking performance, SUPER73 e-bikes are equipped with Tektro disc brakes. Tektro brake adjustment manuals are available on www.tektro.com.

The SUPER73 brake orientation is as follows:
Rear brake = right lever
Front brake = left lever

Brake Models: Tektro Hydraulic brakes HD- E350,
https://tektro.com/en/product/5

Brake Pads: Tektro A10.11
Resin Pad, 2 Piston

On a hydraulic disc brake, pad wear is compensated automatically. Simply check the alignment of the pads with the disc and check that the wheel is aligned too. Good alignment ensures the absence of noise and normal wear of the pads.

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 rotors are only compatible with "resin" pads. Do not use a metal pad with rotors marked "resin".

For better ergonomics and safety, we advise you to adjust the brake levers in a position that feels natural. If you have any questions or concerns, please contact SUPER73.

NEW BRAKE PAD & ROTOR BED-IN PROCESS

Any time you replace your brake pads, rotors, or both, it is important they are properly bedded for optimal performance. To bed your brakes properly after replacement, accelerate your e-bike up to 25kmh and then engage your brakes to bring the e-bike to a near stop, then repeat the process up to 8-10 times. This process allows your pads to wear evenly as well as remove surface glaze and contamination from installation. Surface glaze on pads may cause "squealing brakes."

REPLACING THE PADS

When pads are worn, make sure to adjust both clearances between the rotor and pad so that they are equal and balanced. If only one side is adjusted, it may cause braking failure.

1. Pads and pad springs 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 an Allen wrench.
2. Once free of the caliper, the pads may be easily removed from the pad holder.

The brakes on your SUPER73 are Tektro brand brakes. For any manufacturing problems or questions related to Tektro brakes, you can contact a local Tektro representative. The contact details of the distributors and places of service can be found at the following link: https://www.tektro.com/en/global?area=2&brand=1

BATTERY

The battery is one of the most important components of your SUPER73 e-bike. By following the best practices below, you can optimize its life:

• Do not store a discharged battery. It could go into deep discharge which will reduce its life. Batteries in deep discharge are not covered under warranty.
• Do not use more than one battery at a time.
• Make it a habit to recharge the battery at the end of each ride, so that your e-bike will always be ready to go again.
• Even if the battery can withstand storage temperatures between -10°C and 40°C (23°F - 104°F), you can optimize its shelf life by storing it at room temperature between 18° - 23°C (65°-75°f).
• Observe operating conditions between 4°C - 30°C (40°F - 85°F).
• 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 of the battery in general waste disposal. There are proper disposal methods for lithium-ion batteries. Please check your local waste management regulations.

Do not open the battery or charger. There is a risk of short circuit. Opening the battery or charger will void the warranty. Protect the battery and charger against mechanical damage, heat (in case of prolonged exposure to sunlight), fire, and immersion in water. There is a risk of explosion and/or a risk of injury, death and or property damage. In case of damage and improper use of the battery or charger, vapors may emanate. Keep children away from the battery and charger.

Please follow proper charging instructions before charging the battery. To charge the battery, use only the original charger or charger approved by the manufacturer. Remove the battery from the charger and disconnect the charger from the power supply when charging is complete.

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 pressure.

Range in cold weather:

• Battery capacity will be temporarily reduced when it is cold. This is a normal phenomenon and is not indicative of a damaged or defective battery. Once the battery has been warmed up, the battery capacity should return to normal.
• The battery should be stored and charged at room temperature during cold days. The power consumption warms the battery and you benefit from a good battery life, even when it is cold outside.
• During cold weather, plan for shorter trips or pedal with a lower level of assistance.

Conditions that affect your battery's range:

• Temperature: Extreme cold and heat can affect the battery's capacity.
• Total Number of Charge Cycles: As the battery ages, total capacity can decrease.
• The battery has a total of 1,000 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 cargo on the bike or in a backpack will use more energy.
• Rider Weight: please observe the max weight of 147kg (325 lbs).
• Repeated acceleration from a standing start.
• Poor Maintenance: Under-inflated tires, maladjusted brakes, and/or a dry or dirty chain can decrease range.

Tips for Maximizing Range:

• Charge the battery at a temperature range between 18.3°C- 23.9°C (65°F - 75°F).
• Lithium-ion batteries have no chemical memory, and it is not necessary to discharge the battery completely for the best performance. Charging a partially full battery should have no negative effect.
• Maintain proper tire pressure and clean/lube the chain regularly.
• Operating temperatures between 4°C - 30°C (40°F - 85°F) should increase range.

LIGHTING SYSTEM

The SUPER73 S2 includes a lighting system that is directly connected to the bike's electrical system. If either the rear or front light is no longer operable, please contact SUPER73 for troubleshooting and parts orders. Replacement components should be purchased directly from SUPER73. Please avoid the use of any third-party component that connects directly to the e-bike's electrical system. There are no batteries in the lights. Make sure the front and rear lights are clean before riding. If they are dusty, or dirty, clean them with a damp cloth for optimal visibility and safety.

SEAT

It is not possible to adjust the seat height of the SUPER73 e-bike. It is fixed to the frame by bolts. The minimum seat clamping torque on the frame is 6.78 Nm (5lb /ft). For maintenance, use a cloth and water with a gentle soap for cleaning. Avoid leaving the seat too long in the sun, as the fabric can be damaged by the sun's UV rays. Avoid wearing clothes that may puncture or tear the seat.

The e-bike and its parts are subject to wear and tear, like other mechanical products and parts. Moreover, various materials and parts react differently to wear and abrasion. If the life of a component is exceeded, it is possible that it will suddenly fail, which may present hazards to the rider. Any type of cracks, streaks, or color changes in highly stressed components could indicate the failure of the component. It is highly recommended that use of the e-bike is suspended until all failed components are replaced. It is important to use genuine, properly specified parts for safety-critical components during the replacement of worn parts.

SUSPENSION

Suspension components will require regular maintenance, cleaning, and greasing in order to keep the movement of these components fluid and in good working order. It is recommended to regularly inspect the suspension for signs of damage or wear.

Failure to maintain, check, and properly adjust the suspension system may result in suspension malfunction, which could result in serious personal injury or damage to the e-bike.

STORAGE, PARKING, AND TRANSPORTATION

• Park in accordance with all applicable laws and regulations if you're in a public place.
• Park indoors whenever possible. If you must park outdoors in wet conditions, do not do so for an extended period of time, and afterward park in a dry location to allow the e-bike systems to dry out. When any e-bike is exposed to wet conditions, it requires more frequent maintenance and cleaning to prevent rust and corrosion, and to ensure that all systems work safely.
• Avoid parking or storing your e-bike in direct sunlight and/or excessive heat, such as inside of a parked car on a hot day.
• Switch the power and any lights off to conserve battery power. Remove the key from the e-bike and ensure the battery is locked to the frame in the off position or use the key to remove the battery and bring it with you for security.
• Lock up your e-bike to reduce the risk of theft.
• When pushing or carrying the e-bike, turn off the power to avoid accidental acceleration from the motor, (e.g., by mistakenly engaging the throttle).
• Only use racks (i.e., a bike rack for your car or other vehicle) designed for the size and weight of your e-bike. Pay particular attention to whether the rack can accommodate the width of the tires.
• When carrying your e-bike on a rack for transport, remove the battery beforehand, and place/wrap it securely inside your vehicle, making sure it can't roll around and that its connectors are protected. This will reduce the weight of the e-bike, make lifting and loading it easier, and keep your battery safe.
• Do not leave a battery in direct sunlight or any location that is or may become excessively hot or cold, like a parked car, for extended periods.
• Before using public transportation—buses, trains, etc.—to transport your e-bike, check with the relevant transportation authority for any rules governing weight limits, tire widths, lithium-ion batteries, or any other rules that might pertain to e-bikes.
• Avoid transport of any SUPER73 e-bike on a vehicle rack during rain, which may cause water damage to the electrical components. Contact SUPER73 support if you have questions.
