Forks, Handlebars, Grips, and Seat Adjustment
The forks on your bicycle can affect its handling, so it's necessary to
understand how they work before use. Adjust the fork appropriately
according to your weight and terrain. Ensure the handlebars and stem
are aligned to suit the user and tightened to the recommended torque
value. Handlebar grips should not move easily on the ends of worn
handlebars. Damaged handlebars should be replaced before riding, and
the seat and seat post should be correctly aligned. Before riding, the seat
post clamp should be appropriately tightened, fully closed, and secured.
Battery charging and installation
Make sure the battery is sufficiently charged and operates normally.
Ensure the battery charger is unplugged from the socket and stored in a
safe place before riding. Before use, the battery must be correctly locked
in the battery slot. If the battery has been removed, do not operate the
electrical system. When installing the battery into the battery slot, press
it in hard until you hear a "click".
