Both wheels need to be properly secured before operating your bike.

Mandatory Equipment and Use Locations

Before riding, ensure you have all required and recommended safety equipment and are following all laws pertaining to use an electric bike in your region. For example, these laws may specify the need for mandatory equipment, use of hand signals, and where you can ride.

Changing Components or Attaching Accessories

The use of non-original components or spare parts can jeopardize the safety of your ebike, void your warranty and, in some cases, cause your ebike to not conform with laws pertaining to your bike.
The replacement of original components or installation of third-party accessories or accessories not from Fafrees explicitly recommended for your bike model is at your own risk. Using aftermarket accessories or components that have not been tested by Fafrees  for safety and compatibility may void your warranty, create an unsafe riding condition, damage property or your bike, or result in serious injury or death.

Safety Check Before Each Ride

Always check the condition of your bike before you ride in addition to having regular maintenance performed. If you are unsure of how to conduct a complete check of the condition of your bike before every ride, you should consult a certified, reputable bike mechanic for assistance.
Electrical System
The electric system powers several components on your ebike. It is critical that you familiarize yourself with all aspects of your ebike’s electrical system and check to see if it is working correctly before every ride. The front and rear brake levers contain safety power cutoff switches, which disable the hub motor’s assistance when applied. Both levers should be checked for correct operation. If the brake lever cutoff switches, pedal assistance, or lighting functions abnormally, intermittently, or not working, please
discontinue the use of your ebike immediately and contact the Fafrees Support team for assistance.
Brakes
Ensure that the brakes and their system components are free from damage, properly secured and working correctly. When fully squeezed, both front and rear brake levers should not be touching the handlebar. Take your bike to a certified, reputable bike mechanic to have the brakes repaired if you find a problem.
Tires and Wheels
Your wheels should always spin straight and must be repaired or replaced if they wobble side to side or up and down when spinning. If your wheels become untrue or spokes loosen, which can happen with  normal use, we recommend that a certified, reputable bike mechanic performs all wheel tuning and truing operations on your bike. Do not attempt to true wheels or tighten spokes unless you have adequate knowledge, tools, and experience. Ensure the tires and inner tubes are in good working condition without any visual damage and have the correct amount of air pressure as stated on the tire.

TIRE INFORMATION

F28 MT uses 27.5*2.125″ rubber tires with inner tubes. The tires are designed for durability and safety for regular cycling activities and to be checked before each use for proper inflation and condition. Proper inflation, care, and timely replacement will help to ensure that your bike’ s operational characteristics will be maintained, and unsafe conditions avoided.
Fafrees recommends 40-65 PSI for the stock tires on F28 MT. Always stay within the manufacturer’ s recommended air pressure range as listed on the tire sidewall.
It is critically important that proper air pressure is always maintained in pneumatic tires. Do not underinflate or overinflate your tires. Low pressure may result in loss of control, and overinflated tires may burst. Failure to always maintain the air pressure rating
indicated on pneumatic tires may result in tire and/or wheel failure.
Inflate your tires from a regulated air source with an available pressure gauge. Inflating your tires from an unregulated air source could overinflate them, resulting in a burst tire. Even tires equipped with built-in flat- preventative tire liners can and do get flats from punctures, pinches, impact, and other causes. When tire wear becomes evident or a flat tire is discovered, you must replace the tires and/or tubes before operating the bike or injury to operators and/or damage to your bike could occur.
When changing a tire or tube, ensure that all air pressure has been removed from the inner tube prior to removing the tire from the rim. Failure to remove all air pressure from the inner tube could result in serious injury.

STORAGE INSTRUCTION

If storing your bike for longer than 2 weeks at a time, follow the instructions below to maintain the health and longevity of your battery.

  • Charge(or discharge) the battery to approximately 75% charged.
  • DO NOT leave the battery attached to the bike frame. Remove it from the bike during long-term storage.
  • Store the battery in a dry, climate controlled, indoor location between 0℃– 40℃ (32℉–104℉).
  • Check the battery every month to 75% charged.
  • If stored for a long time, keep the battery cool and dry, and charge the battery for 2 hours every other 3 months.

Failure to follow proper battery storage procedures can result in a non- functional battery. Replacement will not be covered under warranty.
DO NOT cover up the charger while it is charging. The charger air cools and needs to be on a hard, flat surface in an open space. Use the charger with the indicator lights facing upward.
DO NOT open the battery housing, which will void the warranty and can result in damage to the battery, property or cause serious injury and/or death.

Parking, Storage, and Transport
Please follow these basic parking, storage, and transport tips to ensure your bike is well cared for on and off the road.

  • When pushing or carrying the bike manually, turn off the power to avoid accidental acceleration of the motor.
  • Turn off the power to conserve power.
  • Ensure the battery is locked to the frame or use the key to remove the battery and bring it with you for security or storing in a temperature-controlled location.
  • Park indoors when possible. If you must park outdoors in rain or wet condition, leave your ebike outside for only a few hours and then park it in a dry location as soon as possible to allow all of the systems to dry out. As with a regular bike, an ebike used in wet conditions needs more frequent maintenance to prevent rust, corrosion, etc. and to ensure all systems are working safely.
  • Locking up your bike is recommended to ensure your bike is secure. Fafrees Bikes makes no claims or recommendations on the proper lock hardware or procedures to secure your bike, but we do recommend you take appropriate precautions to keep your bike safe from theft.
  • Do not park, store or transport your bike on a vehicle rack not designed for the bike’s size and weight.
  • When carrying your bike an a vehicle rack, remove the battery. This will reduce the weight of the bike, make lifting and loading easier, and allow you to protect the battery by transporting it in the cab of a vehicle.
