Qelectric Expresso S Owner's Manual - page 13
3) The Expresso has an onboard Voltmeter, indicating
the Battery’s approximate state-of-charge. It is
normal for this reading to “sag” somewhat during
acceleration. Excessive Voltage “sag” is a sign of a
depleted or damaged battery. When a battery is
exhausted, if you force it to supply energy, it will
dramatically damage the battery. At this time, the
low-voltage protector will shut off the power
automatically, protecting the battery from further
damage.
5) Put the 4 bolts and washers into the pre-drilled holes
at the bottom of box (A), and through the cargo rack.
Thread the nuts on from below the cargo rack (B). Use a
screwdriver to tighten the bolts, holding the nuts below
with a wrench (C). To avoid breaking the ABS material of
the box, do not over-tighten the bolts.
4) Hold onto the handlebars with both hands. Assume
a well-balanced position on the scooter and push
off with your foot. Your right hand will control the
accelerator. Twist the accelerator slowly to avoid a
sudden rush of speed forward. The speed of the
bike will increase as you twist the accelerator
more. Release the accelerator and apply the
brakes to stop your bike. You will control the
speed of the bike by using both the accelerator and
the brakes. When the brake handle is squeezed it
cuts power to the accelerator.
5) Give the Expresso some acceleration and speed by
first using your feet, then apply the throttle. Try
not to brake and accelerate needlessly. When you
drive against a wind or up an abrupt slope, use
your feet to give the Expresso additional power.
6) Return the key to the OFF position and take out
the key after riding, to secure your property and to
save battery power.

6) To lock the cargo box, insert the key (different from
ignition key) and turn it counter-clockwise to the vertical
position. To open the box, turn the key clockwise into the
vertical position.
7) Attach the Rear View Mirrors to the mounting holes. A
wrench can be used to tighten the lock-nuts at the base
of each mirror.
8) Check if the brakes are properly adjusted. The brake
handles should stop short of touching the hand-grip,
when fully engaged. The rear brake cable can be
adjusted in two places:
