Bicycle Owner‘s Manual
For E-Bike Models
This manual contains important safety,
performance and service information. Read it
before you take the first ride on your new bicycle,
and keep it for reference.

Bicycles Cannot Protect You
Bicycles are lightweight, human-powered vehicles, even Ebikes. Unlike a car, much like a
motorcycle, there is no restraint system for your body, no protective structure around your body.
Crash worthiness cannot be a design criterion. A rider sits on a bicycle and can be easily thrown
of for many reasons including overly hard use of the front brakes or striking an obstacle.
Like any sport, bicycling involves risk of injury and damage. By choosing to ride a bicycle, you
assume the responsibility for that risk, so you need to know — and to practice — the rules of safe
and responsible riding and of proper use and maintenance. Proper use and maintenance of your
bicycle reduces risk of injury.
Many of the Warnings and Cautions say, “You may lose control and fall”. Because any fall can
result in serious injury or even death, we do not always repeat the warning of possible injury or
death.
Because it is impossible to anticipate every situation or condition that can occur while riding, this
Manual makes no representation about the safe use of the bicycle under all conditions. There are
risks associated with the use of any bicycle which cannot be predicted or avoided, and which are
the sole responsibility of the rider.
Safety Messages
In this manual, particularly important information
is presented in the following ways:
Indicates a hazardous situation which, if not avoided, may
result in death or serious injury.
CAUTION
Indicates special precautions that must be taken to avoid
damage.

Charge Bicycle Owner’s Manual Important Safety Information
Teaching Your Child the Rules
137381 Rev 1 (02/20)
Teaching Your Child the Rules
We cannot over-state how import this entire owner’s manual is to the rider’s safety.
We also understand Kids need to be taught ... and to have frequently reinforced ... the following rules
and lessons which adults are already expected to know.
We urge you to take the time to familiarize yourself with this owner’s manual and the rules in this
section.
Teach the rules to your child before you let your child ride unsupervised.
1.Rules
• No playing in the road or in the street.
• No riding on busy streets.
• No riding at dawn, dusk or at night.
• Stop for all STOP signs.
• Ride on the right of trafic.
2.Lessons
The lessons that follow relate to some of the most common real situations that children encounter
when riding their bikes. Go over these situations with your child and make sure the lesson objective is
accomplished.
a. Driveway Ride out
When a youngster rides out of the driveway and is struck by a car, that is called a ride out accident.
What can you do? First, realize the danger of your own driveway. If there are obstructions to the view
of passing motorists (like bushes or trees), trim them back. You might park your car in front of the
driveway, if local ordinance permits. This way, your child can’t use the driveway as a launching pad. But
the most important thing you can do is teach your child about driveway safety. Take your child outside
to the driveway and have him/her practice the following steps:
1) Stop before entering the street.
2) Look let, right and let again for trafic.
3) If there’s no trafic, proceed into the roadway.

17
Important Safety Information
Teaching Your Child the Rules
b. Running a Stop Sign
Car/bike crashes can happen when a cyclist runs a stop sign. Most cyclists who get hit riding through
stop signs know that they were supposed to stop. They just thought it would be OK this time; or they
may have been distracted. The thing to impress upon your child is that while he/she may not get hit
every time, running stop signs will eventually result in an accident.
What can you do? Take your child to a stop sign near home. Explain what it means by emphasizing
the following points:
1) Stop at all stop signs, regardless of what is happening.
2) Look in all directions for trafic.
3) Watch for oncoming cars making let turns.
4) Watch for cars behind you making right turns.
5) Wait for any cross trafic to clear.
6) Proceed when safe.
In order to make this lesson stick, you may have to change your own driving habits. If you creep
through intersections controlled by stop signs, you are showing your child that you don’t really believe
what you preach. For your child’s sake, stop at stop signs.
c. Turning Without Warning
Another major accident type involves cyclists who make unexpected let turns. They neither look
behind for trafic, nor do they signal. The key factor here is neglecting to look to the rear. If the cyclist
had looked, he/she would have seen the danger coming up from behind.
What can you do? Of course, you ought to teach your child not to ride across busy streets - at least
until the child has had some advanced training and is old enough to understand trafic. But in the
meantime, for residential street riding, you can teach your child to always look and signal before
turning let. A big part of this lesson is teaching the child how to look to the rear without swerving.
Take your child to a safe area away from trafic or obstructions to practice riding along a straight line
while looking behind. Stand alongside and hold up a diferent number of fingers on your hand ater the
child rides by. Call his/her name. Ater 15 minutes of practice, a ten year old should be able to look
behind his/herself and identify how many fingers you are holding up - without swerving.

Teaching Your Child the Rules
137381 Rev 1 (02/20)
d. Riding at Dawn, at Dusk or at Night
Most car/bicycle accidents happen at night where an overtaking car hits a bike. (An overtaking car is
one that comes up from behind and passes the cyclist on the let.) These overtaking accidents can be
very serious.
What can you do? First, you should keep your child from riding at dawn, dusk or at night. It requires
special skills and equipment.
Few children have either. Secondly, make sure your child understands that if he/she gets caught out at
dusk or ater dark on a bike, the thing to do is to call you for a ride home. One suggestion is to have
your child carry a cell phone, and as an added precaution, tape a phone number to the bike so that, in
an emergency, an adult will be able to call home.
e. Following the Leader
There is increased risk of car/bike collision if children are following each other, because if the first one
does something dangerous, those following may do it too.
What can you do? Teach your child to always assess the trafic situation for him/herself. When riding
cyclists are riding in a group, each cyclist should stop for stop signs; each cyclist should look to the
rear before making let turns; and so on. One way to get the message across is to play a game with the
child similar to ‘Simon Says’. In this game, however, the emphasis should not be on doing what ‘Simon
Says’, but rather have the child make a decision based on the situation. The child should learn to
ignore what ‘Simon Says’. Children need to learn to think for themselves to ride safely.
Summary
Teach your child early - the earlier the beter. Learning skills such as looking and avoiding hazards
takes time. Be prepared to repeat lessons until your child understands what you’re trying to get across.
Be patient. Your eforts will be rewarded, knowing that your child is aware of safe riding skills.

Important Safety Information
Intended Use of the Bike
Intended Use of the Bike
The intended use of Charge City, Comfort, and XC models is ASTM CONDITION . A description of the
standard is described in the following table:
Condition 2, General Purpose Riding
Bikes designed for riding Condition 1, plus smooth gravel roads and improved
trails with moderate grades where the tires do not lose ground contact.
MAXIMUM WEIGHT LIMIT: Rider: 300 lbs /136 kg , Luggage: 30 lbs/ 14 kg,
Total 330 lbs/ 1250 kg.
Touring Trekking Bikes: Rider: 300 lbs /136 kg , Luggage: 55 lbs/ 25 kg,

relatively narrow tires that are best suited to faster riding on pavement. If you ride on gravel or dirt
paths, carry heavier loads or want more tire durability talk to your dealer about wider tires.
Understand your bike and its intended use. Choosing the wrong bicycle for your purpose can
be hazardous. Using your bike the wrong way is dangerous.
Refer to the drive assist system manufacturer’s manual for instructions regarding all the components
of the drive assist system (e.g. Batery, Drive Charger, Display/e-bike Computer). Always follow the
manufacturer’s instructions for intended use and limitations.

Understanding E-bikes
What is an E-bike?
Electric bikes, also known as “E-Bikes” are bicycles equipped with an electric pedal assist drive
system. An E-Bike IS NOT a moped or motorcycle. E-bikes share components common with pedal-
only bikes.
What is a Drive System?
The drive-assist system consists of a drive unit, a batery, a computer control, and various electronic
components (harness wires, sensors, and switches). There are many diferent drive-assist systems for
difering uses and bike types. Likewise there are various drive-assist system manufacturers (Shimano,
BOSCH, Bafang, Yamaha, etc.)
How does the Drive System work?
A Drive System can be throtle based, pedal assist based, or both.
Throtle Controlled Drive
For a drive system equipped with a throtle, it is important to know that when the drive-assist system is
turned ON, the drive unit engages to provide power when the throtle is pressed.
Pedal Assisted Drive
For a drive system that is pedal assist only, It is important to know that when the drive-assist system is
turned ON, the drive unit engages to provide power only while you are pedaling. The amount of power
provided by the drive unit depends on your pedaling force and the assistance mode/level you set with
the handlebar control unit. With a pedal-assist system, if you stop pedaling, the drive-assist will
disengage.
Limit Assistance / Maximum Speed Allowable
The drive-assist system power reduces progressively and cuts of as the bike reaches a the maximum
allowable speed. The drive-assist re-engages when speed drops below the maximum allowable speed
as long as the pedals are turning. Whenever the drive-assist system is turned OFF, you can pedal the
bike normally. The drive system will not engage.
