RESPONSIBILITY OF THE OWNER!
IMPORTANT:
Reading and following the information and instructions in this manual are essential
to the ability of the owner or any other persons allowed to use this bicycle in order to ride safely.
1. It is the responsibility of the owner or in the case of a younger rider the parents of the
rider to be certain all assembly instructions have been followed, even if the bike has been
assembled by the seller or a professional assembly company.
2. Brakes are essential to safety. Be sure they are checked and working properly before each
use. Remember that any mechanical system changes condition during use and must be
maintained and checked before each use.
3. Rules for bicycle use (bicycle laws) vary from location to location so be certain the rider
knows and understands the rules that apply to bicycle usage in all areas where the bicycle will
be used. Wearing a helmet, light or reflective clothing, using lights and reflectors are examples
of rules which may exist and which make sense as rider safety precautions at all times.
4. Know how to operate the bicycle and all equipment on it before first use and be certain
anyone allowed to use the bike knows how to properly and safely use the bike as well.
5. There are many different types of bicycles and often these types are designed for
different uses. Make sure you know what type unit you have and do not exceed its service
limitations. Be sure you check and understand the bicycle classifications set in this manual,
including size of the unit that is proper for the rider to insure good control during use.
Riders who are too small or large may have control problems. Do not overload a unit with a
rider that is too heavy or too large, and do not attempt to carry extra passengers, packages
or loads on the bicycle. Do not use street bikes for off road riding.
6. Your electric bike is water-resistant, but must be properly maintained to preserve this
condition. Please do not submerge the bicycle or any electric components in water. Water
entering electric components can cause a short circuit and damage the electric components
with possible injury to the rider and others.
7. The battery’s performance can be effected by its environment. Generally speaking, battery’s
discharge performance is better in a higher temperature. Electric power will drop by more
than 1/3 when the temperature is below 32ºF (0ºC). Thus, this e-bike’s riding distance per
charge will become shorter in winter or cold areas. It returns to normal / optimal when the
temperature is higher than 68ºF (20ºC).
8. Do not put any metal objects in charge hole or battery circuit, it may cause a short circuit,
start a fire, or cause an explosion with personal injury or property damage.
NOTE: Max weight of rider+luggage+bike = 220lbs/100kg

CAUTION: For your safety you must carefully read this manual and follow its instructions.
Your bicycle may come with additional instruction sheets that cover features unique to your
bike. Please ensure that you read and become familiar with their contents and retain them with
this manual for future reference. Remember bicycles, in most areas, are subject to the same
laws, rules, and regulations as motor vehicles.
Always wear a CPSC approved helmet when riding your bike.
Learn and follow local and state traffic use laws.
Any major service or adjustments on your bike not covered in this manual should be carried
out by a professional bicycle mechanic. If you wish to make adjustments yourself, this manual
contains important tips on how to do it.
CAUTION: Any adjustments you make are entirely at your own risk. Do NOT use your bike
for freestyle and stunt riding, jumping or competitive events. Even if you are riding a mountain
bike, you should know that off-road use or any similar activities can be dangerous, and you
assume the risk for personal injury, damages or losses incurred from such use. Do not ride
your bike when any part is damaged or not working properly. You must, for your safety and
the safety of other users, consult a professional bicycle mechanic for any questions on
repairs or maintenance.
WARNING: As with all mechanical components, the bicycle is subjected to wear
and high stresses. Different materials and components react to wear or stress
fatigue in different ways. As your bicycle ages, you should inspect it more frequently to
look for deformed, cracked, bent, or loose components. Such conditions may lead to
sudden failure. This may possibly cause injuries to the rider. If something is cracked or
broken, do not ride until repairs have been made.
NOTE: BEFORE TRANSPORTING THE BIKE AND/OR BATTERY, CALL CUSTOMER SERVICE AT

BEFORE RIDING
1. WARNING - ON AND OFF ROAD CONDITIONS: The condition of the riding surface
is very important to your safety. If the surface is wet, or has sand, leaves, small rocks or
other loose debris on the surface where you plan to ride, carefully decrease the speed of
the bicycle and ride with extra caution. It will take a longer time and more distance to stop.
Apply the brakes sooner and with less force. Always apply the rear brake first allowing time
and distance for it to take effect. Then follow by cautiously applying the front brake, in order
to maintain control of the bicycle. Rapid front brake application first may cause a front pitch
over or fall. Learn to use your brakes properly under controlled conditions until you learn
proper braking under all road conditions.
2. NOTICE: State and federal regulations require a full set of reflectors. Some state and
local laws may require that your bike be equipped with a warning device, such as a horn or
bell and most states require a light. The manufacturer and many legal authorities DO NOT
approve or encourage riding at night. Vision is quite limited at dawn, dusk and at night for
bike riders, motorists and by-standers. If you must ride at night, take extra precautions, use
front and rear lights, wear flashers on your arms, wear light-colored clothing, and plan your
route to ride in well lighted areas avoiding heavy traffic areas.
3. NOTE: Always wear shoes when riding a bicycle and avoid loose fitting clothes. Wear a
cuff band or trouser clip to keep pants or other loose clothing from getting caught in the
chain wheel. Long sleeves, long pants, gloves, eye protection, a CPSC approved helmet,
elbow and knee pads are recommended.
Helmet use is required by law in many states and is always a good idea for your safety.
4. CAUTION: WET WEATHER WARNING: Check your brakes frequently. The ability to stop
is critical to your safety. Roads are slippery in wet weather so avoid sharp turns and allow
more distance for stopping. Brakes become less efficient when wet. Leaves, loose gravel and
other debris on the road can also lengthen stopping distance. If at all possible, do not ride in
wet weather. Vision and control are impaired, creating a greater risk of accidents and injury.
5. CAUTION: A bicycle rider’s best defense against accidents is to be alert to road conditions
and traffic in the area. Do not wear anything that restricts your vision or your hearing.
6. When riding, ALWAYS WEAR A CPSC APPROVED BIKE HELMET. It may save your life.
7. Obey all traffic regulations. Most traffic regulations apply to bike riders as well as
automobile operators. Observe all state and local traffic regulations, signs and signals.
Check with your local police station on bicycle licensing and inspection, and where it is
legal to ride your bike.

8
BEFORE RIDING
8. Keep to the RIGHT SIDE of the road. Follow the traffic flow in a straight line close to the
curb. Watch out for opening car doors and cars moving in and out of traffic. Use caution at
intersections.
9. Never carry passengers. This is dangerous and it makes the bicycle harder to control.
Never carry anything that can inhibit your ability to control the bicycle or see the road.
10. When riding in pairs or in larger groups, form a single line along the right side of the
road. Set up a sensible distance between riders. Don’t follow too closely.
11. Always be alert. Animals or people may dart in front of you. Give pedestrians the right-
of-way. Don’t ride too close to pedestrians, and don’t park your bicycle where it can get in
the way of foot/vehicle traffic.
12. Be careful at all intersections. Slow down and look both ways before crossing.
13. Use hand signals. Always let other drivers and pedestrians know what you are going to
do. Signal 100 ft. before turning unless your hand is needed to control the bike.
14.WARNING: NIGHT TIME OPERATION: We do NOT recommend riding your bike at night.
If you have an emergency that requires you to ride at night you must have proper lights and
reflectors. NEVER ride at night without a helmet, taillight, a white front reflector, a red rear
reflector, pedal reflectors and white wheel reflectors. You must be able to clearly see the
surface where you are riding and be seen by others.
15. Never hitch rides. Never hold onto moving vehicles while riding. Never stunt ride or
jump on your bike.
16. ON AND OFF ROAD OPERATION: Avoid the following road hazards: drain grates,
pot holes, ruts, soft road edges, gravel, leaves (especially when they are wet), uneven
pavement, railroad crossings, manhole covers, curbs, speed bumps, puddles, and debris as
all have an effect on your riding and may result in loss of control. Adjust your speed and the
way you use your brakes if you must ride in such areas.
17. If any components becomes loose while riding, (STOP!!) immediately and tighten, or
bring to a mechanic for repair.

BEFORE RIDING
Just a minute spent before each ride can significantly improve your safety and the
enjoyment of your ride. So, EACH TIME before you ride make a habit of performing the
following safety checks:
• Stand in front of the bicycle facing rearward and hold the front wheel securely
between your legs. Try to twist the handlebar and verify that they do not move.
Then pull the handlebars up, trying to lift the bike. There should be no movement.
• Try to push the front wheel from side to side and confirm that it feels tight and
will not wobble. Lift the front wheel up by the handlebars and strike the wheel
downward with the heel of your hand to confirm that it is securely attached to the
wheel. Spin the front wheel and confirm that it does not wobble or contact the fork
or brake pads.
• Try to lift/push down on and twist the seat to confirm it is tight.
• Look at the connection of the pedals to the crank arm. You should not see pedal
screw threads and the pedal should feel firm and be parallel to the ground.
• Apply your brake(s) and make sure they feel firm to the touch, and then spin the
wheel(s). Apply the brakes. The brakes should stop the wheel(s).
• Check to be sure that the fenders and accessories (if equipped) are firmly attached
and will not contact any moving parts. Make sure all reflectors are in position and
not broken.
Now, put on your BICYCLE SAFETY HELMET and enjoy your ride. Your safety is well worth
just a minute. Also, be sure to read and follow the warnings and instructions in this manual.

11
CORRECT FRAME SIZING:
When selecting a new bicycle, the correct choice of frame size is a very important safety
consideration. The ideal clearance will vary between types of bicycles and rider preference. This
makes straddling the frame when off the saddle easier and safer in situations such as sudden
traffic stops. Women can use a man’s bicycle to determine the correct size women’s model.
THERE SHOULD BE A CLEARANCE OF NO LESS THAN
1-2 INCHES BETWEEN THE GROIN AREA OF THE
INTENDED RIDER AND THE TOP TUBE OF THE BICYCLE,
WHILE THE RIDER STRADDLES THE BICYCLE WITH
BOTH FEET FLAT ON THE GROUND.
THE SEAT POST “MINIMUM INSERTION” / “MAXIMUM
HEIGHT” MARK SHOULD NOT BE VISIBLE WHEN THE
SEAT POST IS INSERTED INTO THE SEAT MAST OF
THE BIKE. DO NOT RAISE THE SEAT POST BEYOND
THIS MARK. THE SEAT POST OR FRAME MAY BREAK
CAUSING YOU TO LOSE CONTROL AND FALL. ALWAYS
CHECK TO MAKE SURE THE SEAT POST ADJUSTING
MECHANISM IS TIGHTENED SECURELY BEFORE RIDING.
BEFORE RIDING
1-2”

12
RIDING POSITION:
SADDLE HEIGHT
In order to obtain the most comfortable riding
position and offer the best possible pedaling, correct
saddle height should not allow leg strain from over-
extension, and the hips should not rock from side to
side when pedaling. While sitting on the bicycle with
one pedal at it’s lowest point, place the ball of your
foot on the pedal. The correct saddle height will
allow the knee to be slightly bent in this position.
REACH
To obtain maximum comfort, the rider should not over extend his or her reach when riding.
There should be a slight bend in the rider’s elbows. Refer to the section regarding seat and
seat posts to learn how to adjust the seat post height.

PREPARATION
It is important that you read this owner’s manual before you start to assemble your bicycle.
WE RECOMMEND THAT YOU CONSULT A PROFESSIONAL BICYCLE MECHANIC IF YOU
HAVE DOUBTS OR CONCERNS AS TO YOUR ABILITY TO PROPERLY ASSEMBLE, REPAIR,
OR MAINTAIN YOUR BICYCLE. Remove all parts from the shipping carton. Check to make
sure no parts are loose on the bottom of the carton. Carefully remove the front wheel which
is attached to the side of the bicycle for shipping. Carefully remove all other packing material
from the bicycle. This includes zip ties, axle caps and material protecting the frame.
FRONT WHEEL
1. Remove the nuts, washers and
wheel retainers from the front wheel.
2. Slide the wheel onto the open ends
of the fork. Slip an axle retainer onto each
end of the axle, and hook the retainers
into the holes in the fork end. Loosely
install the washer onto each end of the
axle (serrated end toward the retainer),
then install the hex nut. (Note: there may
be a washer head nut in place of the
washer and hex nut).
3. Center the wheel in the fork and tighten
the axle nuts securely, alternating from one
side to the other to center the wheel.
4. Spin the wheel to make sure that it is
centered in the fork and does not wobble.
If the wheel is not centered, loosen the nuts
and try again.
5. If your bicycle has a quick release mechanism, read and follow the quick release
information on this manual.
Torque requirement: 16-20 ft. lbs.
ASSEMBLING YOUR BIKE

14
QUICK RELEASE FRONT WHEEL
Some bicycles have wheel axles that incorporate a Quick Release (QR) mechanism. This
allows easy wheel removal without the need for tools. The mechanism uses a long bolt (called
a skewer) with an Adjusting Nut on one end, and a lever operating a cam-action tensioner
on the other. With the quick release lever in the open position, insert the front wheel into
the open ends of the fork. Turn the adjusting nut so that the locking lever is moved to the
closed position with a firm action. At the halfway closed position of the quick release lever,
you should start to feel some resistance to this motion. Do not tighten the quick release by
using the quick release lever like a wing nut. If the quick release lever is moved to the closed
position with little or no resistance, clamping strength is insufficient. Move the quick release
lever to the open position, tighten the quick release adjusting nut, and return the quick release
lever to the closed position.
CORRECT QUICK RELEASE AXLE SETTING:
1. To set, turn the lever to the open position so that
the curved part faces away from the bicycle.
2. While holding the lever in one hand, tighten the
Adujusting Nut until it stops.
3. Pivot the lever toward the closed position. When the
lever is halfway closed, there must be firm resistance
to turn it beyond that point. If resistance is not firm,
open the lever and tighten the Adjusting Nut in a
clockwise direction.
WARNING! IF YOU ARE USING A UNIT EQUIPPED
WITH A QUICK RELEASE, ALWAYS MAKE SURE THE
QUICK RELEASE LEVER IS SECURELY CLOSED IN A
LOCKED POSITION. ALSO BE CERTAIN YOUR QUICK
RELEASE LEVER IS ON THE SIDE OPPOSITE TO THE
DISC BRAKE IN YOUR UNIT.
4. Continue to move the lever all the way to the closed
position so that the curved part of the lever faces the
bicycle.
5. The Quick Release is open when you are able to read OPEN. Verify the Quick Release is
closed when you are able to read CLOSED.
6. Repeat process until quick release lever is securley closed in a locked position.

please follow the instructions below:
1. Lean the bike against a wall for support, so that the
right side (chainring side) is facing the wall and the left
side of the bike is facing out.
2. Remove the rear axle nut and washer from the left side rear wheel.
3. Slide the kickstand plate onto the axle, so that it is seated against
the rear dropout.
4. Slide the washer and nut back onto the axle and tighten securely.
5. Leave the leg of the kickstand down so it will support the bicycle during the rest of the
assembly process.
WARNING! THE KICKSTAND IS DESIGNED TO SUPPORT THE
BICYCLE ONLY, NOT THE BICYCLE AND RIDER.
WARNING! Use your kickstand to support the bike when not riding. Allowing your
bike to lay on it’s side can damage the brake levers and cause an usafe riding
condition and could result in injury to the rider.

PEDAL INSTALLATION
1. Apply a small amount of grease to the threads of each pedal. Look for the letter “L” or “R”
on the side or end of each pedal spindle (picture). Turning the spindle clockwise by hand
(Picture), thread the pedal marked “R” into the crank arm on the right (drive) side of the
bicycle. Make sure that you are not “cross-threading”, which can strip the threads in the crank
arm. If the threads do not turn easily, don’t force them. Back the spindle out and start over.
Once the pedal is threaded into the crank arm, tighten the spindle securely to the crank arm
with a 15mm open end or an adjustable wrench.
2. Turning the spindle counterclockwise by hand, thread the pedal marked “L” into the crank
arm on the left side of the bike. Make sure that you are not “cross-threading”, which can
strip the threads in the crank arm. If the threads do not turn easily, don’t force them. Back the
spindle out and start over. Once the pedal is threaded into the crank arm, tighten the spindle
securely to the crank arm with a 15mm open end or an adjustable wrench.
WARNING! IMPROPERLY INSTALLED AND TIGHTENED PEDALS CAN WORK LOOSE,
DAMAGING THE BICYCLE AND CAUSING POSSIBLE SERIOUS INJURY OR DEATH TO THE
RIDER
