ASSEMBLY INSTRUCTIONS
For Front wheel
CAUTION: Your Electric bike is equipped with a front disk brake. Be careful not to
damage the disk, caliper or brake pads when reinserting the disk into the caliper.
Never activate a disk brake’s control lever unless the disk is correctly inserted in the
caliper.
Your bicycle may be equipped with a different securing method for the front wheel
(1) With the steering fork facing forward, insert the wheel between the fork blades so
that the axle seats firmly at the top of the fork dropouts. The cam lever should be on
rider’s left side of the bicycle (fig. 4-1)
(2) While pushing the wheel firmly to the top of the slots in the fork dropouts, and at
the same time centering the wheel rim in the fork:
With a cam action system, move the cam lever upwards and swing it into the CLOSED
position (fig. 4-1). The lever should now be parallel to the fork blade and curved
toward the wheel. To apply enough clamping force, you should have to wrap your
fingers around the fork blade for leverage, and the lever should leave a clear imprint
in the palm of your hand.
NOTE: If, on a traditional cam action system, the lever cannot be pushed all the
way to a position parallel to the fork blade, return the lever to the OPEN
position. Then turn the tension adjusting nut counterclockwise one quarter
turn and try tightening the lever again.
WARNING: Securely clamping the wheel with a cam action retention device takes
considerable force. If you can fully close the cam lever without wrapping your fingers
around the fork blade for leverage, the lever does not leave a clear imprint in the
palm of your hand, and the serrations on the wheel fastener do not emboss the
surfaces of the dropouts, the tension is insufficient. Open the lever; turn the tension
adjusting nut clockwise a quarter turn; then try again.
Spin the wheel to make sure that it is centered in the frame and clears the brake pads;
then squeeze the brake lever and make sure that the brakes are operating correctly.
(3) Hex nuts or hex key bolts which are threaded on to or into the hub axle. (bolt-on
wheel, fig. 4-4 )

ASSEMBLY INSTRUCTIONS
For seat post and pedals
Make sure the seat is tight enough so that you can’t twist it out of alignment.
Pull the seat clamp handle away from the seat post and slide the seat up
or down to adjust it . Move the clamp handle inward toward the
seat post so it is held tight by the clamp.
If necessary, tighten the clamp by twisting the clamp handle clockwise while in the
unclamped position. Then, fold the handle in toward the seat post. This should
require a fair amount of force to ensure the seat post is held tight. If necessary, the
clamp can be further tightened with a 5 mm allen wrench while in the clamped
position. Make sure the seat is not set with the vertical maximum height marks above
the clamp.
Using the 15 mm wrench provided in the tool
kit, attach and tighten the pedals. PLEASE
NOTE –The pedals are marked “L”for Left
and “R”for Right. The left pedal is attached
by turning it counterclockwise and the right
pedal is tightened by turning it clockwise.
Make sure the pedals are tightly attached
to the crank arms to prevent stripping.

BATTERY AND CHARGER CARE
The charger will charge a fully depleted battery in 5—6 hours. The indicator light on
the charger will be red when battery is charging and will turn green when fully charged.
Avoid subjecting the battery to high temperatures, such as directly
under the sun, for prolonged periods of time.
Recharge the battery before it becomes completely discharged. Completely
discharging will reduce the numbers of recharging cycles during the battery’ s life and
limit the capacity. Never store the battery in a discharged state. After much use, your
battery’s charge-holding capacity will decrease. If you find that your battery does not
hold a sufficient charge, you should contact us to order a replacement.
If the battery will not be used for an extended period of time, charge it fully and
recharge it every 2 months. Store it in a cool, dry place. Your battery is engineered
with precision for high capacity and a long, useful life. Do not use it to power other
electrical devices. Improper use of the battery will damage the battery and shorten its
useful life and may cause ire or an explosion. If you experience unusual sounds or
odors coming from the charger or the battery, unplug charger immediately and
contact customer service.
Recharge battery after every use.
•Do not disassemble or alter the battery or battery charger.
•Do not place the battery near ire or corrosive substances.
•Do not allow any liquids on or inside the battery/charger.
•Do not expose the battery/charger to extreme weather conditions.
•Do not operate the battery/charger if damaged.
•Recharge the battery only with a charger specified by the manufacturer.
•Do not use the battery/charger for any use other than its intended purpose.
•Only use the battery/charger on approved products.
Please instruct your children to keep away from the charging place.

SAFETY
Helmet:
Always wear an approved helmet while riding your bike and
follow the helmet manufacturer’s instructions for it, use and
care of your helmet.
It is your responsibility to familiarize yourself with the laws of
where you ride your Bike and to comply with all applicable
laws.
Mechanical Safety Check:
Check the condition of your Bike before every ride. Make sure no nuts, bolts or fixing
are loose, with particular attention to the axle nuts and handlebar stem. Make sure
the tires are correctly inflated with the recommended air pressure that is located on
the side wall of every tire. Check the brakes for proper operation. You must take your
bike in to be serviced and checked by a qualified bike mechanic before 100 miles (161
kilometers) of riding. This is a standard good practice for any new bike as cables will
stretch and components will "bed in". The service must include spoke tensioning for
both front and rear wheels.
Your First Ride:
When you buckle on your helmet and go for your first ride, be sure to pick an area
away from cars, other cyclists, obstacles or other hazards in order to become familiar
with the controls, features and performance of your new Bike.
Additional Passengers:
The Bike bikes are designed for one passenger only (excluding Tandems).DO NOT
carry any additional passengers on the front or rear of the bike.
Weight Capacity:
Bike Electric Bikes are designed with a maximum weight capacity of 220 pounds for
all models. The rear rack maximum weight capacity of a Bike (if applicable) is 25
pounds. Exceeding the maximum weight capacity can result in damage of the bike
which can lead to serious injury.
Tires & Wheels
Make sure tires are correctly inflated. Check by putting one hand on the saddle, one
on the intersection of the handlebars and stem, then bouncing your weight on the
bike while looking at tire deflection. Compare what you see with how it looks when
you know the tires are correctly inflated; and adjust if necessary. Tires in good shape?
Spin each wheel slowly and look for cuts in the tread and sidewall. Replace damaged
tires before riding the bike. Wheels true? Spin each wheel and check for brake
clearance and side-to side wobble. If a wheel wobbles side to side even slightly, or
rubs against or hits the brake pads, take the bike to a qualified bike shop to have the
wheel trued.
