This is not a malfunction. It is a safeguard enga-
ged when the temperature of the battery pack
or the drive unit is too high. Power assist will
be restored once the temperature of the battery
pack or the drive unit has decreased. Also, you
can make this less likely to occur by shifting to
a lower gear than you would usually use (for
example, by shifting from second to first gear).
During the wintertime, store the battery pack
indoors before use.
Set the display correctly.
Stop charging the battery pack.
Check to make sure the battery pack is locked
in place. If this problem still occurs with the bat-
tery pack firmly locked in place, there may be a
loose connection in the battery pack terminals
or wires. Have an authorized dealer inspect your
bicycle.
