5. Recommendations and Maintenance
5.1 General Requirements
E-bikes use metal shells to cover the electric components, so we strongly advise against the use of exces-
sive water to wash the shells and parts around them. Use a soft cloth with a neutral solution to wipe the dirt
off the shells. Afterward, wipe everything dry with a clean soft cloth.
Do not use high-pressure water or air hoses for cleaning; this can force water into electrical components,
which may cause malfunctioning.
Do not wash plastic components with excessive water. When the internal electrical parts are affected by
water the insulator may corrode, leading to power-drain or other problems.
Do not use soap solutions to wash the metal components. Non-neutral solutions may cause discoloration,
distortion, scratching, etc.
Avoid leaving the bike outdoors
When not riding, keep the bike in a location where it will be protected from snow, rain, sun, etc. Snow and
rain can cause the bike to corrode. Ultraviolet rays from the sun can cause unnecessary fading of paint or
crack any rubber or plastic on the bike.
5.2 Maintenance Schedule
To keep your E-bike in optimal condition and your riding experience at its most enjoyable, we strongly
recommend following the suggested maintenance schedule.
