Maintenance - Velotric Thunder 1ST Manual

Maintenance

Regular maintenance is important to your safety and the longevity of your ebike. Any part of
a poorly maintained ebike can break or malfunction leading to an accident. Velotric strongly
recommends that you follow a regular maintenance schedule based on normal use. If you
ride your ebike more than the time indicated, perform maintenance more frequently than
recommended. If a part malfunctions, check and service it immediately, or seek help from a
qualified mechanic. If a part has worn or damaged, replace it before the next time you ride the
ebike.
Read and understand the recommendations and the recommended service schedule below.
Basics
■ Always store the ebike in a clean dry place to avoid rust and damage to the battery.
■ If storing your battery for long periods, follow the recommendations in "Battery Storage" .
■ Clean the frame of the ebike with a damp cloth and mild non-corrosive cleaner. For more
detailed information, refer to "Cleaning" .
■ Do not submerge the ebike in water as the electrical system may be damaged. Be sure to store
the ebike under shelter and avoid leaving it out in the rain. For more detailed information, refer
to "Storage" .

■ Ensure that the tires of the ebike are always inflated to a pressure
within the recommended range printed on the tire sidewall.
■ Ensure that all components of the ebike are in good working condition
before each ride. For more detailed information, refer to "Before Every
Ride" .
