e-Bikes Introduction
MEANINGS OF WARNINGS:
This symbol is important. See the word “CAUTION” or “WARNING” which follows it.
The word “CAUTION” is before mechanical instructions. If you do not obey these
instructions, mechanical damage or failure of a part of the bicycle can occur.
The word “WARNING” is before personal safety instructions. If you do not obey these
instructions, injury to the rider or to others can occur.
Riding an e-bike is similar to riding a regular bike but oers a motor that provides assisted
power when pedalling.
WARNINGS:
• When mounting your e-bike, always apply full front and rear brake lever pressure to keep
the unit from moving while mounting and do not put feet on the pedals until you are
sitting on the seat.
• Your e-bike travels at higher speeds than most riders are used to when pedaling a
traditional bike. It is very important that you are aware of your surroundings and obstacles
around you and be extra careful when you rst start moving. It’s important to watch the
path surface you are on which can cause tires to slip or atten.
• An electric bike is heavier and requires more time to stop due to weight and faster
speeds. Practice starting, riding and stopping in a closed space with no other vehicles and
always ride with hands near the brake levers.
• Before riding, familiarize yourself with the products operation.
• Do not become distracted by the Display. Change Display settings only when stopped.
• Never ride at speeds faster than you are comfortable with.
• Always start riding with the lowest assist speed.
• Avoid riding this product on wet, frozen, oily or unpaved surfaces or under the inuence of
drugs and/or alcohol. Avoid uneven surfaces, potholes, surface cracks and obstacles.
• Avoid riding in rain and wet weather and always store e-bike indoors.
• Always obey State and Local Laws when using this product. Serious injury can result
from the unsafe operations of this vehicle.
• This product is not designed to be jumped. If jumped, even from the curb, The e-bike
Frame could break causing serious injury or death. If jumped, the warranty is void.
e-Bike Range:
• Higher assist setting will shorten the distance your e-bike can travel.
• Always keep tires at proper ination pressure (shown on side walls).
• Heavier riders will shorten riding range.
• Hills or rough terrain will shorten riding range.
• Starting and stopping eects riding range.
• Always fully charge your e-Bike before each ride.
This “Class 1” e-Bike complies with Federal Governments guidelines, with regard to total
watts and top speed.

Maintenance
Inspection of the Bearings
Maintenance:
Frequently check the bearings of the bicycle. Have a bicycle service shop lubricate the
bearings once a year or any time they do not pass the following tests:
Headset Bearings:
The fork should turn freely and smoothly at all times. With the front wheel o the ground,
you should not be able to move the fork up, down, or side-to-side in the head tube.
Crank Bearings:
The crank should turn freely and smoothly at all times and the front sprockets should not
be loose on the crank. You should not be able to move the pedal end of the crank from
side-to-side.
Wheel Bearings:
Lift each end of the bicycle o the ground and slowly spin the raised wheel by hand. The
bearings are correctly adjusted if:
• The wheel spins freely and easily.
• The weight of the spoke reector, when you put it toward the front or rear of the
bicycle, causes the wheel to spin back and forth several times.
• There is no side-to-side movement at the wheel rim when you push it to the side with
light force.

26
Maintenance
Lubrication
WARNING:
• Do not over lubricate. If oil gets on the wheel rims or the brake shoes, it will reduce
brake performance and a longer distance to stop the bicycle will be necessary. Injury to
the rider or to others can occur.
• The chain can throw excess oil onto the wheel rim. Wipe excess oil o the chain.
• Keep all oil o the surfaces of the pedals where your feet rest.
• Using soap and hot water, wash all oil o the wheel rims, the brake shoes, the pedals,
and the tires.
• Rinse with clean water and dry completely before you ride.
• Using a light machine oil (20 W), lubricate the bicycle according to the following table:
Lubrication Table (as equipped)
What When How
Pedals every six months Put four drops of oil where the axles go into the
pedals.
Chain every six months Put one drop of oil on each roller of the chain.
Wipe all excess oil o the chain.
Derailleurs every six months Put one drop of oil on each pivot point of the
derailleurs.
Brake Levers every six months Put one drop of oil on the pivot point of each
brake lever.
Wheel Brakes every six months Put one drop of oil on the pivot point of each
cantilever brake.
Brake and cable every six months Put four drops of oil into both ends of each cable.
Allow oil to soak back along the cable wire.
Rear Sprocket
Cluster
every six months Lay the bicycle on its left side. Slowly turn the
rear wheel clockwise. Put four drops of oil in the
crack between the rear sprockets (which are
stationary) and the freewheel body (which is
turning clockwise).
Shock Fork every six months Lift up the rubber fork boot and dab a small
amount of grease on the fork leg just above the
plastic bushing.

Introduction
Fitting the Rider to the Bicycle:
A bike which you ride only on paved surfaces, should give you a minimum
stand-over height clearance qof 2 inches (5 cm). A bike that you’ll ride on
unpaved surfaces should give you a minimum of 3 inches (7.5 cm) of stand-
over height clearance. And a bike that you’ll use o road should give you 4
inches (10 cm) or more of clearance.
NOTE: See Assembly sections for Seat adjustment.
Adjust the seat height so that you can put the heel of one foot
on a pedal with leg extended straight A- and so the opposite
foot can reach the
ground with tip of
foot B. This will give
your knees a slight
bend when pedalling
with the ball of the
foot.

Maintenance
Tires (as equipped)
MAINTENANCE:
• Frequently check the tire ination
pressure because all tires lose air slowly
over time. For extended storage, keep
weight o of the tires.
• Do not use unregulated air hoses to
inate the tire/tubes. An unregulated
hose can suddenly over inate tires and
cause them to burst.
• Replace worn tires.
WARNING:Do not ride or sit on the unit if a
tire is under inated. This can damage the tire, inner tube
and rim.
INFLATING THE TIRES:
• Use a hand or a foot pump to inate the tires.
• Service station meter-regulated air hoses are also
acceptable.
• The maximum ination pressure is shown on the tire sidewall.
Before adding air to any tire, make sure the edge of the tire (the bead) is the same distance
from the rim, all around the rim, on both sides of the tire A. If the tire does not appear to be
seated correctly, release air from the inner tube until you can push the bead of the tire into
the rim where necessary. Add air slowly and stop frequently to check the tire seating and the
pressure, until you reach the correct ination pressure.
