o Never ride with headphones. They mask traffic
sounds, distract you from concentrating on your
surroundings, and their wires can tangle in the moving
parts of the Expresso, causing you to lose control.
If you find problems that you cannot solve them yourself
during your inspection and maintenance, please send your bike
to your servicing dealer for help. Never take apart or repair the
bike by yourself. If it causes any problem and voids the
warranty, a service fee will be imposed.

4) When proper chain tension is achieved, tighten the
axle nuts and re-secure the rear brake housing to
the frame.
If the chain needs to be taken off from the Expresso, for
instance for rear tire replacement, be sure to re-orient the
chain properly when put it back on.
If the chain ever falls off spontaneously, this indicates
either a mis-alignment of the sprockets, or a lack of
proper chain tension.
Cleaning
1) Never wash the bike using high-pressure water, as
it will cause damage to the electric bike.
2) Never use lubricant to clean the metal parts of the
bike and never apply lubricant to the drum brake
and the tire.
o Never carry a passenger. The maximum carrying
capacity is 300 lbs.
o Never ride barefoot or wearing sandals.
o Don’t jump with your Expresso. It puts great stress on
everything from frame and forks to cranks and pedals.
Riders who insist on jumping their Expresso risk
serious damage to their Expresso as well as to
themselves.
o Never carry anything which obstructs your vision or
your complete control of the Expresso or which could
become entangled in the moving parts of the
Expresso.
o Never hitch a ride by holding on to another vehicle.
o Never ride your Expresso while under the influence of
alcohol or other drugs.
o If possible, avoid riding in bad weather, when visibility
is obscured, at dusk or in the dark, or when you are
very tired. Each of these conditions increases the risk
of accident.
o Never allow children to ride. Never allow others to ride
without reading and understanding these instructions.
Operating Reminders and Suggestions
o Review all instructions carefully before riding the
Expresso.
o Follow all rules and regulations in your area for
operating a motorized bicycle. Obey the same road
23
4
laws as all other road vehicles, including yielding the
right-of-way to pedestrians, and stopping at red lights
and stop signs.
o Ride predictably and in a straight line. Never ride
against traffic.
o Use the signal lights to indicate turning or stopping.
o Ride defensively. To other road users, you may be
hard to see.
o Concentrate on the path ahead. Avoid potholes,
gravel and dirt, wet road, oil, curbs, speed bumps,
drain grates and other obstacles.
o Be alert for unexpected events, such as opening car
doors or cars backing out of concealed driveways.
o Be extra careful at intersections and when preparing
to pass other vehicles.
o Familiarize yourself with all the bike's features.
Practice signal lights, braking and use of the horn.
The changing method of the front tire is the same as
common bicycle. It is more complex to change the rear
tire because of the motor and brake assemblies, and
associated wiring and cabling. If you are not comfortable
with undertaking this operation, you can ask your
servicing dealer or mechanic to change it.
Lubrication
You should inspect and maintain your Expresso and
lubricate the mechanical power transmission components,
and chain. The brake cables may also need lubrication
Lubricate the brake cables with silicone or graphite
lubricant. Maintenance period: one month.
Lubricate the fork Shock Absorber tube, axle rim, and the
axle ball bearing with SH/T0386 lubricant, bicycle or
lithium grease. Maintenance period: one year.
Chain Adjustment
Adjusting the chain
o Don't carry packages or passengers that will interfere
with your visibility or control of the bike. Don't use
items that may restrict your hearing.
1) Put the Expresso up on its Kickstand.
o Maintain a comfortable stopping distance from all
other riders, vehicles and objects. Safe braking
distance and forces are subject to the prevailing
weather and road conditions.
3) Adjust the nuts on the chain-tensioners (eyebolts).
Turning the nuts clockwise will pull that side of the
axle rearward, tightening the chain. The nuts
should be adjusted together, so that the rear wheel
is aligned with the direction of travel, and so that
the two chain sprockets remain parallel.

2) Loosen the rear axle. Loosen the fasteners for the
rear brake.
22
Expresso after each ride. You should charge your
Expresso if it has not been used for 30 days or more.
WARNING
Do not place the battery near heat or fire. Do not expose
the chargers to water.
OTHER MAINTENANCE
Your Expresso should be returned to your servicing dealer
or bicycle/scooter mechanic once a year for a thorough
inspection and adjustment. This can guarantee the
comfort, safety and the normal operating life of the
Expresso.
Front and Rear Brakes
The adjustment of the front brake is the same as in a
common motorcycle. It is very important to brake
effectively and to be sure that the battery shut-off device
is in good condition. When the brake lever is released, the
wheel should spin without resistance. If it drags, it will
waste a lot of electric power. You should change the
brake’s shoes when they are worn to one-third of their
original thickness.
The rear drum brake is very similar to the brakes on
electric scooter products. When this brake is exhausted,
a squealing sound will be heard upon brake application.
Front and Rear Tires
21
Wet weather impairs traction, braking and visibility,
both for the rider and for other vehicles sharing the
road. The risk of accident is dramatically increased in
wet conditions. In wet weather you need to take extra
care. In wet conditions, the stopping power of your
brakes (as well as the brakes of other vehicles sharing
the road) is dramatically reduced. This makes it harder
to control speed and easier to lose control. To make
sure that you can slow down and stop safely in wet
conditions, apply your brakes earlier and more
gradually than you would under normal, dry conditions.
Decrease your riding speed, avoid sudden braking, and
take corners with additional caution. Keep in mind that
there is a direct, but inverse, relationship between
speed and controllability.
Be more visible on the road. Wear reflective clothing
and use safety lights.
Potholes and slippery surfaces such as lane markings
and train tracks all become more hazardous when wet.
Night Riding
A rider is very difficult for motorists to see at dusk, at
night, or at other times of poor visibility. If you must ride
under these conditions, check and be sure you comply
with all local laws about night riding; follow the Rules of
the Road, and take the following precautions:
Make sure that your Expresso is equipped with correctly
positioned and securely mounted reflectors. Make sure
your clothing or cargo does not obstruct a reflector or
light. Ensure that the front lights are on.
6
Wear light colored, reflective clothing and accessories,
any reflective device or light source that moves will help
you get the attention of approaching motorists,
pedestrians and other traffic.
Ride slowly. Avoid hazards, such as potholes and curbs.
Avoid areas of heavy traffic, dark areas, and roads with
speed limit over 35 mph. If possible, ride on routes
already familiar to you.
Ride at night only if necessary. Slow down and use
familiar roads with street lighting, if possible.
Other Reminders
The Expresso works best on level ground. Use caution
while going down an incline, such as a hill or a ramp. Hill
climbing and repeated acceleration/braking will exhaust
the battery much more rapidly.
The Expresso has an electrical brake cutoff system.
When you engage either brake, the throttle becomes
inoperative. Release the throttle before braking. Do not
“ride” the brakes.
The battery does NOT require deep discharging. If your
Expresso is put into storage, re-charge its battery at least
once every 90 days.
Do not store your Expresso in direct sunlight for an
extended time.
Store your Expresso in a dry place. Exposing your
Expresso to rain, snow, or other precipitation may result
in damage.

3) Keep the charger(s) and battery away from water
to prevent electrical shock and shorting. The
charger(s) is intended for indoor use only.
4) Plug the end of the 2 charger’s cords into the
sockets of the adaptor first. Next connect the
adaptor to the Expresso. Then plug the chargers’
AC cords into the wall outlet.
5) Read the charger label to learn about the chargers’
indicator lights, and their meanings.
6) Generally, a short drive will require a short time to
re-charge, and a long ride will require a longer
time. A complete (90%) discharge may require 6
hours to recharge. To prevent electrolysis (battery
fluid loss by hydrogen generation,) do not charge
for longer than eighteen hours.
7) ALWAYS CONNECT BOTH CHARGERS WHEN
RECHARGING.
Before riding the electric bike for the first time, you must
charge the batteries for 4-6 hours using the supplied 2
chargers. To charge, pull the protective cover from the
charging sockets. Then plug the charger into the
charging sockets, and plug the chargers into a wall outlet.
IMPORTANT
The electric bike is powered by four 12V/14Ah batteries
wired in series to provide 48 volts of potential. All
batteries charge simultaneously. You should charge your
20
Frequent braking and acceleration, driving into
headwinds, up hills or with cargo will all cost a lot of
battery energy. In these conditions, the Expresso will not
reach its normal range.
Battery Charging
Be sure to charge the battery completely if you will not
use it for a long period. Ideally, you should charge it
every 20 days. Even a healthy battery will discharge itself
slowly. Even with its power off, the Expresso Battery
state-of-charge will decline gradually over time.
Remember to fully charge the battery before your first
ride. The battery may be low when you receive your new
Expresso.
1) While charging the Battery, keep the key switch
OFF.

COMPONENTS
Replace the battery if there are leaks, visible breaks or
cracks.
Dispose of used batteries by taking them to a recycling
center, or according to state and local laws.
Battery Temperature Sensitivity
Ambient temperature will affect almost every kind of
battery. Usually, the battery shows good discharging
capability at higher air temperature. When the air
temperature is under 0 ºF, the battery power will decline
more than one third. So it is natural that the Expresso will
not reach its normal mileage in winter or in cold weather.
When the air temperature is up to 68 ºF, the Expresso
will achieve its normal range capability.
When the ambient temperature is over 110 ºF (as when
exposed to summer sunshine for a long period), batteries
and other electric components usually run in an abnormal
fashion.

What Does “Maximum Range” mean?
To determine the Expresso’s maximum per-charge
distance, the testing environment was:
Under these conditions, the Expresso’s maximum range is
up to 35 miles.

What’s Inside Your Expresso Battery
The Battery is composed of four 12 Volt, 14 Amp-hour
capacity batteries, in series, for a total capacity of 48 V,
14 Ah.
The component batteries are a standard, commercially
available size. Keep three things in mind, however,
should you choose to service your battery.
1) The batteries are soldered into place. Replacing
batteries will require soldering equipment and
skills.
2) Batteries can be extremely dangerous. If allowed
to short-circuit, they can cause burns, create
blinding arcs, or explode, causing serious injury. If
you accept this risk, work slowly, and exercise
utmost care! Work with only one wire at one time.
3) Batteries, solder, and soldering vapors contain
lead, a toxic substance that can build up in your
body. Minimize your exposure to lead by wearing
gloves, providing good ventilation when soldering,
and washing hands after soldering or handling
batteries. You should NEVER simultaneously solder
and eat snack foods!

Battery Care and Maintenance
ASSEMBLY AND SETUP
If your Expresso was removed from its carton and “set
up” by retail store personnel, there is no guarantee it was
properly set up. Please observe and follow this checklist,
even if your Expresso was out of its carton when you
purchased it. This will ensure its safe and reliable
operation.
1) Remove your Expresso from its shipping carton. The
Expresso weighs about 145 lbs, so get help, and use care.
Cut away any residual packing materials with a sharp
knife or scissors. Tools needed for setup are included in
the Expresso tool kit.
2) Inflate the front and rear tires to 35 psi.
3) To make sure the alignment is correct, stand in front
of the vehicle, using both legs to hold the front wheel in
straight-forward position. Use both hands to grab the
handle bar and turn it into normal driving position (90
degree angle from the front wheel).
4) Locate the Cargo Box. Find 4 bolts and 4 washers for
mounting the box onto rear frame.
What to Expect of Your Batteries, Ideally
The battery is a sealed lead-acid type, with a gel
electrolyte. With normal use, it can last for well over 300
charge/discharge cycles.
Know that normal use should mean partial, and not
complete discharging. If you employ “shallow” discharge
cycles, using less than 30% of battery’s capacity, the
battery can achieve up to 1,200 charge/discharge cycles.
Thus, it is good to charge the battery after each ride.
A
partial discharge will require less time on the chargers.
What to Expect, Realistically
The battery can keep its performance for about 200
charge/discharge cycles, with high current and deep
(80%) discharging. The storage capacity of the battery
will decline after 200 times recharging. If you re-charge
the battery before it is exhausted, you dramatically
extend the battery’s cycle life.
In Summary
Always try to recharge the Battery Pack within 24 hours
after use to maximize battery cycle life and prevent
damage.

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.
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.
15
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.
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:
12
•
At the cable end bracket, just before the lever,
with 8 and 10 mm wrench adjustments, and
•
At the end of the lever, with a 10 mm nut fastener.
The front brake is adjusted
at the end of the cable, at
the saddle nut.
ROUTINE OPERATION
A) Pre-Ride Check
1) Be sure the tires have enough air. Low tire
pressure risks rim pinching (tube failure) and
lowers your range (distance per charge).
2) Be sure the battery is fully charged. Riding on a
low state-of-charge will reduce range, and can
damage the battery.
3) Verify the proper adjustment and function of the
brakes.
9) Check that the crank and rear chain sprockets are
aligned, and that the chain has proper tension. Proper
chain tension allows for a slight (±½ inch) movement up
and down, when pulled with fingers at the point between
the sprockets. Lubricate the chain with chain or lithium
grease, not with a spray oil.
10) Your Expresso has been in transit and storage. You
must charge the batteries before riding it. Charge the
battery by plugging in the 2 included charger cords into
the Expresso’s Charger Ports.
4) Make sure the Expresso is in good mechanical
order. Visually inspect and hand-check the vehicle,
and snug any loose bolts, screws, or other
fasteners.
5) With the Expresso on its Kickstand, turn the key
switch and apply the throttle, to verify the motor’s
smooth operation. Apply the brake to stop the
motor. Verify that the throttle is inoperative when
either brake is applied.
B) Steps to Startup
1) Roll the Expresso off its Kickstand. Mount the
Expresso. Adjust the Rear View Mirrors so that you
can see clearly behind you.
2) Insert the key into the key switch and turn the key
from OFF to ON.
