Notes: do not clean the bike with alcohol, gasoline, kerosene or other corrosive and volatile chemicals solvents to prevent dire damage. Do not wash the bike with a high-pressure water spray. During cleaning, make sure that the bike turned off, the charging cable is unplugged, and the rubber flap is closed as water leakage may result in electric shock or other major problems. When the bike not infuse, keep it indoors where it is dry and cool. Do not put it outdoors for along time. Excessive sunlight. overheating and over cooling accelerate the battery pack’s life span.
Battery Maintenance

1. Use original battery packs. use of other models or brands may bring about safety issues:
2. Do not touch the contacts. Do not dismantle or puncture the casing. Keep the contacts away from metal objects to prevent short circuit which may result in battery damage or even injuries and deaths;
3. Use original power adapter to avoid potential damage or fire;
4. Mishandling of used batteries may do tremendous harm to the environment. To protect nature environment, please follow local regulations to properly dispose used batteries;
5. After every use, fully charge the battery to prolong its life span.

Devices are not intended for use at elevations greater than 2000m above sea level prolonged exposure to UV rays, rain and the elements may damage the enclosure materials. store indoors when no tin use.
2. In daily use, try to avoid recharging the bike after completely exhausting the battery. If the battery is low. charge it as soon as possible.
3. Please charge the bike every other month to preserve the battery.

Recommended Service Intervals

Regular inspection and maintenance are key to ensure bikes from jasion function as intended. and to reduce wear and tear on their systems. Recommended service intervals are meant to be 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 be performed at the time or mileage interval that comes first in the following table.

Your cables, spokes, and chain will stretch after an initial break-in period of 50-100 mi (80-160 km). and bolted connections can loosen. Always have a certified, reputable bike mechanic perform a tune-up on your bike after your initial break-in period of 50-100 mi (80-160 km) (depending on riding condi­tions such as total weight, riding characteristics, and terrain). Regular inspec­tions and tune-ups are particularly important for ensuring that your bike remains safe and fun to ride.

Tire Inflation and Replacement

• The EB5 Romer ST employs 26″x2.25″rubber tires with inner tubes. The tires are designed for durability and safety for regular cycling activities and need to be checked before each use for proper inflation and condition, Proper inflation, care, and timely replacement will help ensure that your bike’s operational characteristics will be maintained, and unsafe conditions avoided.

• Jasion recommends 45-60 PSI for the stock tires on the Jasion. 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. like those that come with bikes from jasion, can and do get flats from punctures, pinches, impact, and other causes. When tire wear becomes evident or a flat tire is discovered, tires and/or tubes must be replaced before operating the bike or injury to operators and/or damage to your bike from Jasion 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.
  Using aftermarket tires or inner tubes, not provided by jasion may void your warran­ty, create an unsafe riding condition, or damage to your bike. If required by law, ensure replacement aftermarket tires have sufficient reflective sidewall striping.

• For more information on tire or tube replacement procedures, or questions about tire inflation, visitjasionbike.com/pages/help-center or contact Jasion Product Support.
