This is not a malfunction. It is a
safeguard engaged when the
temperature of the battery pack or the
Drive Unit is too high. Power assist will

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).

low (roughly 10 °C or
below)?

pack indoors before use.

battery pack firmly locked in place, there
may be a loose connection with the
battery pack terminals or wires. Have an
authorized dealer inspect your bicycle.
