4.3 Gear box
Your A2B is equipped with a
derailleur actuated by the two
pressure levers at the right-
hand side of the handlebar.
To facilitate pedalling (e.g. at
gradients), you operate the
large lever located in front of
the handlebar and marked with
A in the drawing. In this way,
you shift down and have to
pedal faster to maintain your
speed. If you want to go faster
(in plain or downhill), you shift
up one gear using the smaller
lever which is marked as B
in the opposite figure and
located behind the handlebar
from the driver's point of view
and may pedal slowlier, but
you have to use more efforts.
Do not ever move the pedals backwards when shifting into
another gear. The chain might jump off and you might lose the
control over the bicycle which could lead to accidents with severe
or even fatal injuries and/or material damage. Always pedal evenly
and in forward direction when shifting into another gear.

The derailleur operates independently from the motor. Using the
derailleur, adjust a gear which enables pleasant pedalling and helps
the motor at the same time.
4.4 Lighting
Turn the on/off switch located on the headlamp into the respective
direction to switch on or off the lighting.
