• Check wires and connectors regularly to ensure that the connectors are secured and undamaged.
• Clean this e-bike with a damp cloth and dry it with a clean dry cloth. If necessary, clean the frame by applying a mild, non-corrosive detergent mixture to a damp cloth.
• Do not expose this e-bike to rain or any other corrosive materials. Once exposed to rain, it should be dried. The chain and other unpainted steel surfaces should be treated with rust protection.
• Be careful when cycling on beaches or coastal areas, as salt can corrode your e-bike. Keep the unpainted parts clean and rust-proof.
• If the paint on the metal is scratched or chipped, use a patch to prevent it from rusting. Clear nail polish can also be used as a backup.
• Clean and lubricate all moving components regularly, and tighten and adjust them as required. Check all hardware periodically to make sure they are securely connected and working well.

Recommended Service Intervals

Safety Checklist
We recommend you follow this safety checklist before each ride or after every 20-50 miles (32-80 km).

Tire Inflation and Replacement

• This e-bike uses 26″ x 1 .95″ rubber tires, which are safe for regular riding. Check their inflation level before each ride. Correct inflation, maintenance, and timely replacement can ensure that your electric bicycle functions properly. We recommend 40-65 PSI (2.8-4.5 BAR) for both front and rear tires.
• It is essential to maintain proper air pressure in the tire at all times. Do not underinflate or overinflate tires. Low pressure can cause losing control, and over-inflated tires can burst. Failure to always maintain the air pressure level indicated on the tire sidewall may cause tire and/or wheel failure. Inflating a tire from an unregulated air source can overinflate the tire, which can cause the tire to burst.
• Even tires equipped with built-in flat-preventative tire liners can get flats from punctures, pinches, or other causes. When tire wear becomes evident or a flat tire is discovered, you must replace the tires and/or tubes before operating this bike, or injury to operators and/or damage to your bike may occur.
• When changing a tire or tube, ensure that all air has been removed from the inner tube before removing the tire from the rim. Failure to remove all air pressure from the inner tube could result in serious injury, unsafe riding conditions, or damage to your bike.

TROUBLESHOOTING

Please follow these listed rules and contact a certified bicycle mechanic regularly to ensure that your e-bike is safe and comfortable to ride. For more detailed information, see “Recommended Service Intervals” and “Safety Checklist” in this manual.
