Congratulations!
You are now the proud owner of a
Fifield Electric Bicycle!
Your electric bicycle is like any
other bike, but with electric pedal
assistance and throttle. The same
precautionary steps while biking
should be taken to prevent any
accidents or injuries.
“Electric” means that your e-
bike will assist you when you are
pedaling if you so choose. You may
also pedal normally with no
assistance at all or twist the
throttle to get moving with no
pedaling necessary.
The electric bicycles’amount
of assistance will depend on what
level you set it to; the speed varies
from 0 to 5. The fastest speed this
bicycle travels is 20 MPH (32 Km/h).
Know your electric bicycle
If misused the features of your
electric bicycle may cause you to
lose control of the e-bike. Before
riding in fast or more difficult
situations, learn the function and
performance of all the mechanisms
of your bike by riding at slower
speeds in a flat, empty space.
The maximum weight is 286lbs
(130 kg). When riding, please pay
attention to the weather and load
on your bike; if any changes are
noticed adjust your riding style
accordingly. When it is raining or
snowing, please increase braking
distance as a safety precaution.
This e-bike is not afraid of rain
or snow, but it cannot be
submerged in water. When water
submerges the motor it can cause
a short circuit to occur and
damage the electric apparatus.
Specifications
The Jetty comes standard with
sleak black (metal) spokeless rims
and aluminum alloy rims to match
the frame.
The 10.4 Ah lithium battery can
propel the bike at speeds up to
20mph using its 250W brushless
rear-drive motor. The range varies
from 25-35 miles, based upon
dependent variables.
Chain driven, the Jetty is also
equiped with shimano Alfine 8-
speed external gearing. This is
paired with Shimano disc brakes
and Kenda reflective tires with

kevlar belt.
All together the bike weighs 48
pounds and folds to near half its
size.
Accessories
The jetty comes with a headlight
and tailight that can both be
operated through the LCD control
screen (page 10).
Also, a foldable kickstand and
rear cargo rack.
A USB charging outlet can also
be found under theblack rubber
cover next to the charging port
(page 13).
A bell can also be found on the
left handle bar infront of the
throttle.
A built in bike lock can also be
found on the rear wheel beneath
the seat stem.

Check your e-bike before riding
everytime
Before operating your electric
bicycle, inspect it carefully to avoid
accidents or damage. Inspect your
bike completely before each ride.
Turning the power on and then
accidentally twisting the throttle
can result in the e-bike lurching
forward and may cause an
accident, damage, or injury.
If the battery was removed,
place the battery back into its
location and be sure to lock it and
remove key. Check to see that the
battery is fully charged (battery
level indicated on screen) before
riding and check the air pressure of
the tires (45 –50 psi). Be sure to
test the front and back brakes, as
well as the condition of the
handlebars and the front and back
wheels.
Make sure that everything is
fastened and secure. Be sure to
check that all quick releases are
locked and in good working order.
Taking off
As the bike starts, accelerate
slowly; do not try to get to your
maximum speed right away
because doing so could damage
the electric components.
If applied, the hand brake will
automatically cut the power to the
motor as well as release the
throttle. You should avoid using
the throttle while brakes are
being applied so that you do not
overload the motor. When starting
from an elevated path, pedal as
much as possible so that the
electric power will last longer.
Pedaling more than using solely
the throttle will lenghten the life of
the battery and motor.
Going downhill
When going downhill, please
do not turn the power off. If you
are not pedaling or using the
throttle, there will be no power
assist when traveling downhill. If
CAUTION
Always keep the power switched
OFF before riding. Turn on only
after you are ready to ride.
WARNING
Do not leave the key in the
battery lock while riding to avoid
breaking the key.

you turn the power off, it could
easily damage the controller and
motor.

BEFORE YOUR FIRST RIDE

As you continue to ride, the
battery will decrease
porportionally based on the
amount of power you are using. As
the battery decreases, the bar will
go down one by one. If the bar
goes out completely, you can still
pedal your e-bike just like a regular
bike. Be sure to charge your
battery when you get to an
electrical outlet.
To get the best distance out of
your electric bike, refrain from
excessive stop and go braking and
coast as much as possible.

SAFE RIDING
7
Local riding laws
Most state and local areas
have specific laws for cyclists.
Please check with your local
Department of Motor Vehicles for
clarification. Again, these e-bikes
are not considered motor vehicles,
but may be subject to additional
regulation based on the state you
live in. Some of the common laws
include mandatory lights and
reflectors on the bikes.
Safety precautions
Be sure to ride an appropriate
distance away from cars,
pedestrians, and other obstacles.
In addition, try to avoid potholes,
drain grates, and other
imperfections in the road which
may affect your ability to ride. A
bell is provided to alert others of
your approach.
OBEY all traffic laws relevant to
the operation of bicycles and
electric bicycles.
KEEP both hands on the
handlebars at all times and do not
hang objects from the handlebars.
RIDE predictably and in a straight
line. Never ride against traffic.
USE the correct hand signals when
turning or stopping. If you do not
know the proper hand signals, it is
important you learn them before
riding on the road.
USE extreme caution when you are
near other vehicles. Ride
defensively and assume that other
people on the road do not see you,
and be careful at intersections
when starting from a stopped
position.
DO NOT suddenly brake in the rain
or on slippery surfaces.
WEAR a helmet for your protection
and bright or reflective clothing to
make you more visible.
DO NOT wear lose clothing
because it can get caught in the
bicycle.
When going over train tracks, be
sure to ride perpendicular to the
tracks or walk your bicycle across.

SAFE RIDING

Varying riding conditions
Wet conditions
Like any other moving object,
when it is wet or snowing, there is
less traction. This applies
specifically to the brakes on the
bike; they will not perform as well
as they do in dry climates. Be sure
to brake earlier because it will take
a longer distance to come to a full
stop. Ride at a slower speed and
try to be more visible.
Low visibility
Even though your bicycle
comes with headlights, rear lights,
and reflectors, in situations where
there is low lighting it may make it
difficult for people to see you. Be
sure to see and be seen in your
environment. Wear reflective and
bright colored clothing to enhance
visibility for others.

ASSEMBLY

1. Handlebars: When your e-bike is first shipped the handlebars be
properly attached, but in the folded position. This can be seen in the
left side image. There are two steps to resolve this. First, simply
straighten the handlebar frame until it is perpendicular to the
ground. When this is complete, use the metal clasp on the side of the
frame to lock the collapsible joint in place. If done properly, there
should be no movement of the handlebars.
Next, use the depicted tool below to loosen the 2 screws on the
handlebar clamp just enough for you to roll the handlebars toward
the seat until they are in the correct position (shifters facing you at
the fight level and the LCD facing up toward your face). Make sure to
then tighten down the screws.

ASSEMBLY
10
2. Frame: In addition to the handlebars being out of place, the middle of
the bike will also be in the collapsed. To correct this, simply unfold
the bike until the frame is perfectly straight and use the metal clasp
on the frame to lock the joint together. Once closed make sure to
push in the black lock found above the clasp (shown in the image on
the right. There should be no movement at the collapse point if done
properly.
3. Pedals: The pedals will come in their own wrapping. Once unwrapped
look inside the threaded section to determine what side of the bike
the pedal goes on (depicted below). Attach the pedals by putting a
washer on the threaded part o the pedal and using the provided
wrench to tighten the pedals in their place. The pedals are also
collapsible for ease of storage. To do this, simply push the pedal
inwards and fold it either up or down. This is best done using your
foot.

ASSEMBLY
11
4. Registration: When assembly is complete, please refer to our website
(www.fifieldebikes.com) to register your new electric bicycle! On the
site, you will be prompted to answer a few brief questions and
provide two serial numbers. The first, the frame serial number is
located directly below the handlebars and above the front wheel on
the front of the bike. The second, the motor serial number is written
on the motor which is located in the center of the rear wheel.

Battery Indicator
The five battery bars represent
the capacity of the battery. When
the battery is low the battery
frame on screen will flash to notify
that it needs to be recharged
immediately.
Error Code Information
If an error code appears, take
note of what code is displayed.
Contact a service center to get
your bicycle repaired. An error
code will be displayed in the
bottom right corner in place of the
normal “WATT” display.
For more information on the LCD
screen, refer to our website to
download the extended version of
the manual.
Pedal assistance
Your pedal assist will start
once you start to pedal and stop
once you stop peddling. You are
able to adjust the amount of
assistance on the LCD screen by
adjusting the + / - button. If you do
not want any assist, bring your
bike to a stop and power off the
system. If the handbrakes are
applied, the pedal assist will cut
automatically. You do not need to
turn the power off when going
downhill.
Throttle
The throttle is located on the
left side of your handlebars. It is a
one speed throttle which does not
engage unless the bike is pedaled
to engage the motor, and then the
throttle can be used and pedaling
can stop. To engage the throttle,
turn the throttle towards you
while seated on the bike. There is
an automatic SHUT OFF of the
throttle on the brake levers. Every
time the brake lever is pressed, the
power from the motor is
disconnected.
Gears
There are 7 external gears on
your bicycle. The gears are located
on the right side of your
handlebars. In order to shift
between gears, simply move the
shifter up and down until you find
a suitable gear to ride in.
Battery
The battery supplied is the top
quality 10.4 amp Lithium Battery
and was designed specifically for
this electric bicycle. The battery is
sealed safely within the frame of

the bike to ensure no damage can
come to it.
Your battery should be
recharged after each use. The
normal lifecycle of the battery, if
continuously discharged and
recharged, is about 3-5 years or
800-2000 recharges, after which
the storage capacity will decline.
Again, be sure to fully charge the
battery before the first use.
The range in distance on a full
charge is approximately 25 –35
miles depending on your weight
class and terrain. Higher weight
classes and uneven surfaces will
require more power than lighter
weights and flatter surfaces. This
equals to 5 –6 hours of continuous
riding, again depending on your
weight class and terrain.
Battery performance is
affected by temperature, and will
perform better in warmer
temperatures. When the
temperature is below 32°F (0°C),
the battery current may decrease
by 1/3. Consequently, the travel
range in cold environments is less
than in warmer environments, but
will return to normal when it the
battery returns to room
temperature.
Frequent braking/starting,
riding uphill/against strong winds,
starting from a standstill, or riding
on rough/muddy roads will use
extra power and lower range.
Here a few tips to prolong the
battery life under these conditions:
Frequent braking/starting –try
to look ahead and coast rather
than stop and go frequently.
Riding uphill/against strong
winds –pedal to supplement the
battery power.
Starting from a standstill –use
pedals to help bring you up to
speed, not just the throttle.
When battery meter indicates
low power remaining, switch to
manual power and avoid using
the battery.
If the bicycle is being stored,
remove the battery and recharge
it every month.
WARNING
Do not attempt to access the
Lithium battery in any way. Doing
so may cause chemical, electric,
and/or fire hazards.
