GENERAL NOTES ABOUT RIDING

Motor Assistance

• The motor provides assistance when the cranks are rotating. The amount of assistance increases depending on the amount of pedaling frequency. The slower you pedal, the lower assistance will be provided.
• Your CYKE bike can also be ridden like a regular bicycle with-out motor assistance by switching the assist level to PAS0 (OFF) on the display.
• As mentioned in this manual, with the system powered up, the motor support will activate as soon as the cranks are rotating. This can also happen when not actively riding the bicycle, e.g., when the bicycle is in a work stand or flipped upside down and the cranks are turned or the chain is moved (which then turns the cranks), when walking alongside and pushing the bicycle and the cranks are turned, or any other scenario where the cranks are turned, and the wheels are moving, whether intentionally or unintentionally. What this means is that the system should be powered off when motor assist is not desired to avoid any unintentional engagement of the motor.

WARNING! The system must always be powered off when not in use or performing any maintenance on the bicycle.

Brake
Sometimes the motor doesn’t stop working immediately when you stop pedaling, you need to cut off the power by pinching the brake.

WARNING! CYKE bike is equipped with brake sensors, so do not replace the brakes.

WARNING! Be careful to keep body parts and other objects away from the moving disc brake rotors to avoid injury. Also, disc brake rotors can get extremely hot with extended use. Be careful and do not touch a rotor until it has plenty of time to cool.

CAUTION: Do not allow any oil or grease to get onto the disc brake rotor and the brake pads. Riding the bicycle with oil or grease on the disc brake rotor and brake pads may prevent the brakes from operating correctly.

Changing Gears

When pedaling, pull the upper lever with your index finger to shift your bicycle into a higher gear (harder/small cog) and push the lower lever with your thumb to shift your bicycle into a lower gear (easier/large cog).

CAUTION: Do not shift gears when applying full force on the pedals. Change one gear at a time and only when pedalling.

Electric Bicycle Riding Tips
Because of the electric motor assist, your electric bicycle offers a unique riding experience compared to a normal bicycle.

Below are some riding tips and information that may reduce component wear and increase battery range:

• Please pay attention to your speed going into a corner and stop pedaling before entering it. Otherwise, you may carry too much speed which may cause you to lose control and fall.
• Ride at a comfortable, efficient cadence and look ahead.
• When braking force is applied, more energy is needed to get the bicycle back up to speed.
• Shift gears regularly to stay in an optimal cadence range and downshift before coming to a stop.
• Reduce pedal force before initiating a gear shift to reduce drivetrain wear.
• Braking while steering may reduce the ability to control your bicycle.
• Only carry the cargo you need. More weight drains the battery faster.
• Do not expose your bicycle to prolonged excessive heat.
• Check the tire pressure regularly as low pressure can cause the tires to roll inefficiently.

WARNING! Check your bike as soon as possible after partial or complete submersion. Most likely its electrical system has been damaged and is unsafe to use. Carefully remove the battery pack from the-bike and take it to a safe location OUTDOORS, away from flammable materials. To properly dispose of the battery, place it in a clear plastic bag and take it to your municipal household hazardous waste drop-off center. To find the closest facility in your area check with your local City Hall or Fire Department.

WARNING! UNDER NO CIRCUMSTANCES should you attempt to charge a battery pack that has been partially or totally submerged in water. Attempting to charge a compromised battery can result in a very dangerous fire that generates significant heat, toxic gasses and is extremely difficult to control.

Battery Storage
If the E-bike or the battery will not be used for a long time, comply with the following instructions during storage:

• Do not store the battery in an environment with temperatures below -20C(-4F) or above 45 C(113 F).
• Do not expose the battery to an environment with fluc-treating temperatures. The ideal storage temperature range is between 10C (50F) and 25C (77F).
• Store them in a dry environment to protect the battery against moisture to avoid the corrosion of electrical contacts.
• Do not store the battery near the flammable items.

The battery will switch to offline if not be charged in time under the following circumstances:

• When the battery level reaches to 0%, it will enter sleep mode within 10 minutes.
• When the battery level is between 0%~10%, it will enter sleep mode in 48 hours.
• When the battery level is above 10%, it will enter the sleep mode in 14 days.

Please completely charge before returning battery and bike to normal use.

WARNING! Deep discharge of the battery may cause the internal short circuit. Heating the battery to very high temperature may cause fire. Avoid deep discharge during the use and storage of battery. When not in use, the battery shall be fully charged once every 2 months at least. Do not carry a deep-discharged battery on the E-bike.

When the battery switches to offline, you need to long press this button or charge the battery to wake up the power supply before restoring the normal use of your e-bike.

MAINTENANCE

Basic Bike Care
To ensure safe riding conditions you must properly maintain your bike. Follow these basic guidelines and consult a certified bike mechanic at regular intervals to ensure your bike is safe for use and fun to ride.
Properly maintain batteries by fully charging them every two weeks or more often. Please check the Long-Term Battery Storage section for information about storing the battery for longer than two weeks before the next rides.

• Never immerse or submerge the bike or any components in water or liquid as the electrical system may be damaged.
• Periodically check wiring and connectors to ensure there is no damage and the connectors are secure.
• As for cleaning, wipe the frame with a damp cloth. If needed, apply a mild non-corrosive detergent mixture to the damp cloth and wipe the frame. Then wipe it with a clean, dry cloth.
• Store the e-bike under shelter and avoid leaving it in the rain or exposed to corrosive materials. If it’s ex- posed to rain, dry your bike and apply anti-rust treatment to chain and other unpainted steel surfaces.
• Special care should be given to extend the life of your bikewhen used in coastal areas or areas with salty air or water as riding there exposes your bike to salt, which is very corrosive. Wipe down your bike frequently and wipe or spray all unpainted parts with anti-rust treatment as damage from corrosion is not covered under warranty
• If the hub and bottom bracket bearings have been submerged in water or liquid, they should be taken out and regreased. This will also prevent the bearing from accelerated deterioration.
• If the paint has become scratched or chipped off, use touch-up paint to prevent rust. Clear nail polish can also be used as a preventative measure.
• Regularly clean and lubricate all moving parts, tighten components, and adjust them as required. Regularly in-spect all pre-attached and optional component hardware to ensure proper torque spec, secure attachment, and good working condition.

Cleaning Your CYKE

• Remove the battery pack from your bike first before cleaning the e-bike. Use a damp cloth with mild soap as needed to clean the outside of the battery. Do not insert anything into the electrical connector on battery for any reason as it should remain clean and dry when the bicycle is properly cared for.
• The e-bike body can be cleaned with water from a garden hose, mild dish soap, and a damp cloth. But avoid spraying electronics on the handlebars, electrical connectors, ends of the hub motor where axle protrudes, rear cassette, front sprocket and chain. Rinse the dish soap away thoroughly with low pressure water and thoroughly dry the bike while paying extra attention to remove any water from electrical components or connectors. A hair drier or a vacuum can also be used to remove water from places that are difficult to reach.
• Reinstall the battery after the e-bike has been cleaned and thoroughly dried. Make sure the battery is properly installed and locked into the e-bike.

WARNING! Never immerse the bike or any of the components in water or other liquid. This can damage the electrical system and will void your warranty.

WARNING! Never clean the bike with high pressure jetted water as it can enter the electrical components and damage them.

WARNING! Always store the bike in a dry location. Thoroughly dry the bike after riding in the rain or washing it. For standing water can enter electronics or cause corrosion resulting in damage to the electrical system.

Tire Inflation and Replacement

• Select proper-size tires according to the side wall of your e-bike tires. These tires use a rubber inner tube to retain air pressure. The tires on your e-bike are designed for cycling on typical terrains and surfaces. Please only replace the tyres with a similar tire design of the same size. Always check all items related to Tires and Wheels listed in the Pre-Ride Check before each ride. Properly inflated tires will help ensure the maximum tire lifespan, the best bike performance, and the possible longest riding range.
• Keep your tires inflated at 5-30 P.S.I. all the time. Never exceed the maximum pressure listed on the tire side wall. Tires will lose air pressure over time., so always check the tire pressure before operating the e-bike. Low tire pressure can result in damage to the wheels that will be more difficult and expensive to repair.
• When replace the tires, always choose equivalent tires with reflective side walls. All the CYKE e-bikes are equipped from the factory with this type of tires to provide the most visibility of you and your bike in low light conditions. Keep the tires clean to ensure the reflective side wall can function properly.

Recommended Service Intervals
Regular inspection and maintenance are key to ensure the e-bike function and last as intended, and to reduce wear and tear on their systems. Recommended service intervals are only used as guidelines. Real-world wear and tear, and the need for service, will vary with conditions of use. We generally recommend inspections, service, and necessary replacements to be performed at the time or mileage interval that comes in the following table.

WARRANTY POLICY

Length of Warranty

• Every bicycle has a useful product lifespan. This limited warranty is not meant to suggest or imply that the frame or components can never be broken or will last forever. This limited warranty covers manufacturing defects that occur within the normal lifespan and use of the product.
• For CYKE bikes, the serial number is the singular certificate for after-sales (warranty).
• Before purchasing, please check the serial number in detail. In case of a worn serial number, please do not purchase the E-bike.
• The electric bicycle serial number is noted on the Master Carton and the bottom tube of the frame. The battery serial number is noted on the battery pack.

Warranty Conditions
This limited warranty applies only to the original owner of the bicycle and is not transferable to subsequent owners or other transferees of the electric bicycle. Only the original owner of an electric bicycle purchased from CYKE online or CYKE authorized distributor or retailer is covered by Limited Warranty. The Warranty Period begins upon your receipt of the electric bicycle and shall end immediately when any sale or transfer of the electric bicycle is made, and under no circumstances shall the Limited Warranty apply to any subsequent owner or other transfer of the electric bicycle.

• Bike Frame: 5-year warranty
• All other mechanical components: 1-year warranty
• Electrical components: 2-year warranty

For any warranty claim to be considered, the E-bike must be in an assembled, reasonably clean and sanitary condition and accompanied by the original, dated sales receipt for the bicycle (be sure to keep your receipt in a safe place!).
This limited warranty is void if the bicycle is subjected to abuse, neglect, improper repair, improper assembly, lack of proper maintenance according to the owner’s manual, alteration, modification, installation of incompatible parts, corrosion, an accident or other abnormal, excessive, or improper use. This limited warranty is void if the bicycle is used in a rental or bike sharing program.

Damage resulting from normal wear and tear, including the results of fatigue, is not covered. It is the owner’s responsibility to regularly inspect and properly maintain his/her bicycle. Some items that typically exhibit damage from normal wear and tear include:

• Bearings
• Bearing Races
• Chain Rings
• Cassettes
• Tires
• Tubes
• Saddles
• Chain
• Brake Pads
• Brake Disks
• Wheel Hubs
• Spokes
• Handlebar Grips
• Cables and Housing
• Bushings

Damage to a Covered Component during shipping is not covered by this Limited Warranty, but CYKE will replace such damaged Covered Components if you:

• Notify CYKE of a Covered Component damaged in the shipping process within thirty (30) days of your receipt of the electric bicycle;
• Provide CYKE with a dated picture of the damaged Covered Component;
• Return all original packaging and paperwork included with the electric bicycle;
• Note any immediately recognizable damage on the shipper’s Bill of Lading prior to signing off on the ship-ment. Shipping damage claims are very time sensitive and it is your responsibility to immediately inspect the electric bicycle for damage upon receipt.
• Paint fading caused by the effects of ultraviolet light (UV) or outdoor exposure is not covered by this limited warranty. All labor charges for warranty service, including the transfer of components and/or any installation of new components, are the responsibility of the bicycle owner.
• Due to product evolution and obsolescence (such as products that have been discontinued or are no longer kept in stock), some frames or components may not be available for older or limited-edition models. In these cases, CYKE may elect to provide a replacement that it determines to be the most nearly comparable model, but sourcing and paying for components is the responsibility of the bicycle owner.
• All determinations under this limited warranty will be made in the sole discretion of CYKE, including but not limited to the decision to repair or replace a defective product, and what replacement product is the most nearly comparable product then available.
• The remedies stated above are the exclusive remedies under this warranty. Any and all other remedies and damages that may otherwise be applicable are excluded, including, but not limited to, incidental or consequential damages, damages to other property, or any punitive damages.
• This is the only warranty made by CYKE on its frames and components, and there are no warranties which extend beyond the description herein. Any warranties that may otherwise be implied by law including, but not limited to, any implied warranty of merchantability or fitness for a particular purpose, are excluded.
• Please refer to the documents included with your bicycle for possible further restrictions.
• This limited warranty gives the consumer specific legal rights. The consumer may also have other legal rights which vary from state to state or country to country. Some states and countries do not allow the exclusion or limitation of incidental or consequential damages or warranties, so the above limitations or exclusions may not apply to you. If it is determined by a court of competent jurisdiction that a certain provision of this limited warranty does not apply, such determination shall not affect any other provision of this limited warranty and all other provisions shall remain in effect.
