3.3 Pedals Installation
Attach the pedals by screwing them on to the crank.
Note, there are Left and Right pedals. Left pedal is attached to the left side crank by screwing it counter-
clockwise. Right pedal is attached to the right side crank by screwing it clockwise.
Note: Correct side stamped on the pedal edge
3.4 Seat adjustment
3.4.1 Height:
Proper saddle height occurs when your leg is at the bottom of the stroke and your leg is almost fully
extended. The knee should not lock, nor should your hips have to rock over to one side to fully depress
the pedal. There should be a natural bend in your knee, just as if you were standing. There is some
variation to this measurement; some people prefer to be slightly higher, others lower. This variation is
on the order of millimeters, never as large as centimeters and there is a generally accepted “correct”
saddle height.
Loosen quick release handle and adjust height as necessary

3.4.2 Position:
The angle of the saddle should be almost parallel with the ground. Again, as with saddle height,
there is some subtle variation (1 - 2 degrees), but it is never extreme. If the rise is too steep, this
will cause numbness and discomfort, especially on longer distance rides. A negative slope will
result in the rider constantly slipping forward, forcing more pressure on the palms and increased
neck and back pain. This is uncomfortable and is to be avoided. A saddle that is almost parallel
to the ground is ideal, as it supports the weight of the rider without causing numbness or
putting excess pressure on the hands.
Loosen hex bolt underneath the seat and adjust angle and/or length as necessary
3.5 Brake Adjustment
Your bike is equipped with front and rear disc brakes. Properly adjusted brakes are an essential thing.
You don't want them to fail at the last minute.
Take note that the rear brake is on the left side of the handlebar, and the front brake is on the right side
of the handlebar.
Please use extra caution to keep your fingers away from the rotating disc brake rotor.
The disc brake rotor is sharp enough to inflict severe injury to your fingers if
caught within the openings of moving disc brake rotor also the rotor becomes hot after
usage therefore let it cool before performing any post ride adjustments.
Note: front and rear brakes are identical therefore following instructions are related for
both sides

c. Loosen the two mount adjustment bolts that hold the main body of the brake onto the
mounting yoke or fork. These bolts aim forward along the axis of the rotor, with one above and
below the calipers. The holes for these bolts allow for some side-to-side "play" that positions
the caliper mechanism. (Don't take the bolts out; just back off the tension in the bolt enough to
allow the rotor to "shift" a bit on its mounting.)
Once these bolts loosen, squeeze brake lever (brakes are applied) and tighten adjustment bolts
equally –release brake lever only after making sure the bolts are tighten.
d. Loosen cable pinch bolt and screw in barrel adjuster.

14
e. With the cable loose, push the brake arm upward a bit until it stops moving. (At this point, it has
pushed the pads against the rotor.) Now back off about 1/2 to 3/4 inch of cable length.
Tighten the cable down. Grasp the brake lever to see if the brake engages at a comfortable spot.
Usually, you should have at least one inch between the handlebar and the brake lever when the
brake is "full on." If necessary, readjust the position of the brake arm on the cable, until the
brake engages at a reasonable point in the lever-pull. (It doesn't need to be exact -- you can fine-
tune with the barrel adjuster on the brake lever or on the caliper.)
3.6 Rear Derailleur (gear shifter) Adjustment
Properly adjusted derailleur will benefit enjoyable ride and prevent rider from over-shifting hints
• On the rear cog set (cassette), the largest gear offers the lowest gear ratio and the most torque.
• The best gear combination for steep uphill is the largest rear cog.
• On downhill use the smallest cog.
• In general, find the right combination of gears to allow you to maintain a steady pedal stroke.
• Always pedal forward while shifting, reducing pedaling pressure slightly to avoid jamming or straining
the chain.
• If you hear any rubbing or grinding noise after shifting, refer to this manual or see your local dealer.
Drivetrain misalignment may result in a broken chain, derailleur moving into spokes, or chain jamming,
potentially causing serious injury. If you are at all unsure of your abilities to properly adjust the
derailleurs on your bicycle take it to your dealer to have your bike's drivetrain inspected and adjusted as
necessary.

4.3 Pre ride inspection –checklist
4.3.1 Tires and Wheels
Before you get on your bike, check your tires to make sure they are properly inflated (recommended
pressure ≈40 PSI. Take a quick look all the way around for places where the rubber might be cracked,
gouged or worn.
Check nuts or/and quick release mechanisms that hold your wheels in place. Verify that your wheels are
securely fastened so they don’t come out while riding.
4.3.2 Brakes
Squeeze your brake levers to make sure that they apply enough pressure to stop your bike and that you
don’t have any problems with fraying or stretched cables.
4.3.3 Seat & Handlebar
Check to make sure that your handlebar is set at the right height, that the stem is fastened tightly and
that your seat is at the correct height and angle.
4.3.4 Helmet
As you get ready to put on your helmet, look it over once to make sure there are no cracks on the outer
shell or inner surface. Check too, that the straps are adjusted so that the helmet fits snugly, and sits
down on your forehead.
4.3.5 Chain and Gears
Check that your chain turns smoothly through your front and rear sprockets and doesn't rub against the
derailleurs. You can do this as you pedal when you first set off. At the same time, quickly run your bike
through its range of gears to make sure there are no problems with rough shifting, chain slippage etc.,
and that the drive train is free from excessive grime and doesn’t need lubrication.
Quick, Easy, and Very, Very Important
All told, these checks should take you less than 30 seconds, and really just require a visual inspection of
your bike’s main components. This is smart and easy way to make sure you stay as safe as possible when
you’re out on your bike.
ATTENTION: After the power is on, if the rider twists the throttle the bike will lurch forward! Do not
turn the power on until you are ready to go. The hand brake will automatically cut the power to the
motor as also will releasing the throttle. While starting or climbing a hill, pedal as much as possible, so
that the electric power will not be drained too much. At the same time, it can lengthen the life of the
battery and motor.

18
ATTENTION: When riding down hills, do not turn off the power, otherwise the controller and motor will
be easily damaged which is NOT covered under warranty.
While running, if the battery power is getting low, the battery meter will lessen. At this time you should
pedal your e-bike like a regular bike and charge the battery as soon as you get to an electrical outlet.
Turn off the power while parking. If you decide to push your bike for any reason, make sure to turn the
power off, so you don’t accidentally turn the throttle making the electric bicycle start suddenly and
cause an accident. To help get the best distance out of your electric bike, refrain from a lot of braking
and coast as much as possible.
5Important Instructions
Safeguard your battery to insure continued high performance.
The normal full-cycle battery life, if it is continuously discharged and recharged, is between 400–600
cycles) after which the storage capacity of the battery will gradually decline.
CAUTION! Fully charge the batteries before the first use!
Failure to do this can result in decreased battery performance for the life of the bike.
Make sure battery is fully charged before you use the bike.
Battery performance is affected by the temperature and is generally better in warm temperatures.
When the temperature is below 32º F (0º C), the battery current may decrease by a third. Consequently,
the travel range on a full charge in cold environments is much less, but will return to normal when the
temperature is back to room temperature.
Frequent stopping and starting, riding uphill, traveling against a strong wind, starting from a standstill,
riding on rough or muddy roads, and carrying more than one person or heavy loads will consume extra
battery power and shorten the range.
A few tips to prolong the battery life during these conditions is as follows:
Frequent braking –try to look ahead and coast rather than frequently stopping and starting.
Riding uphill or against a stiff wind –pedal to supplement the battery power
When starting from a standstill, use the pedals to help bring you up to speed.
When the battery meter indicates the voltage is low, switch to manual power and avoid using the
battery, so you don’t shorten the battery life.

19
To prevent premature failure of your battery and for your warranty to remain in effect on your battery;
YOU MUST CHARGE THE BATTERY AT LEAST ONCE PER 6-8 WEEKS!
Always turn off the bike before and during charging to prevent serious damage to the controller and to
the batteries!
This electric bicycle can be used in the rain. However, the motor and other electrical parts must not be
submerged in water. The controller, motor and other electrical devices may be short circuited causing
damage, which is NOT covered by warranty, and creating possible dangerous situations.
DO NOT use chargers or other components other than that which has been approved by this company.
This company is not responsible for damages caused by the use of other products not specifically
designed and tested for use with this electric bike.
Battery chargers contain sensitive electronics. Improper use, dropping, or sudden jolts can damage the
charger and its internal electronics which is NOT covered by warranty. Do not leave the charger on for
more than 10 hours!
Check all nuts, bolts, screws, and spokes to make sure they are tight before riding. If any screws, nuts, or
bolts are loose, put some thread lock on the threads and then tighten.
6Safety Precautions
Before operating your bicycle, inspect it carefully to avoid accidents or damage.
Do not drive close to other vehicles.
ALWAYS keep the power switched OFF until you are seated on the bike and ready to ride.
Turning the power on and then accidentally twisting the throttle can result in the bike lurching
forward and may cause an accident, damage, or injury.
NEVER attempt to disassemble the motor, battery, controller or throttle. This can result in
injury, fire, or damage to the bike.
ONLY use the charger supplied with your bike to charge the battery. Using the improper charger
can result in fire or explosion.
KEEP the batteries out of the reach of children.
Obey all traffic laws relevant to the operation of bicycles and electric bicycles.
Use the turn signals (if equipped) or hand signals at all times when making turns.
KEEP both hands on the handlebars at all times.
DO NOT hang objects on or under the handlebars.
DO NOT brake suddenly in the rain or on slippery, wet surfaces.
USE extreme caution when riding near other vehicles. Assume they do not see you, and be
careful at intersections and when starting from a stopped position.

20
When cleaning your electric bike, do not use a steady direct stream of water from a hose. Use a
cloth to avoid short-circuiting any electrical components. Your electric bike has a durable finish
and does not need to be waxed. Clean with a mild detergent and buff to restore its original
shine.
Please wear a safety helmet and glasses for your own protection whenever riding.
Wear bright clothing to help make you visible to other motor vehicles.
Do not wear loose clothing that can become caught on the bicycle.
Do not leave the charger connected to the battery for more than 10 hours.
7Battery charging and precautions
It is important to charge your batteries after every long use (battery gauge 50% or less). This will extend
the total life of your battery. Once the charger has indicated that your battery is fully charged the green
light will come on, unplug the power source from the bicycle and the electrical outlet and store in a cool,
dry place. Do not leave the charger plugged into the battery for long periods of time as this can damage
the battery.
1. Turn off the display
2. Insert plug of the charger into charging port of the battery. You can charge your battery while
still in the bike or you can take it out of the bike and charge where it is most convenient.
3. Insert the charger into the wall outlet. Do not plug charger into outlet until you first plug the
charger into the battery charging port. A red light will come on. It can take up to 8 hours to
recharge the battery completely. On most chargers, a green light will appear when it is fully
charged.
4. When the light turns from red to green, it indicates that the battery is full. If possible, charge for
an additional 2-3 more hours to fully balance the battery. After the green light comes on, the
charger is in trickle charge mode. If you will be gone for many hours, you should unplug the
charger. This is especially true in hot weather. Avoid overcharging and damaging the battery.
The charger will become warm during charging, so keep charger away from any flammable
materials. You can also charge the battery when it is removed from the bicycle. This is especially
convenient during cold nights or when your bike is not parked near an electrical outlet. Because
specifications of the charger may change in the process of production, please read the
information on the charger itself or the charger manual (if included) in detail before using.
Always charge the bike in a dry and clean place. Keep the charger dry and clean.
7.1 Battery Precautions
Do not touch the two poles of the battery with your hands when the battery is removed for
charging. Also, the two battery poles should not be touched with any metal or other material
that conducts electricity.
While charging, put the battery in a secure place where children can't reach.
