Bicycling is an active sport with inherent risk. A wide range of injuries are
possible. Due to the nature of bicycle riding, the situations you encounter
while riding, you will be exposed to the risk of serious injury, paralysis or
death. This risk cannot be eliminated. You can minimize the risk in many
ways. Begin by reading the complete Charge Bicycle Owner’s manual
accompanying this bike and available online at .chargebikes.com,

ADJUSTMENT INSTRUCTIONS:
Adjustable Stem Instructions,
in your Charge Bicycle Owner’s
Manual.
1. The handlebars are located
in a cardboard sleeve on the
right side of the bike. Slide the
handlebars out of the sleeve and
place them on the tray made by
the top of the cardboard shroud.
Make sure the wires and cables
running from the handlebars to
the bike frame aren’t twisted.
2. Ensure the power is OFF
before continuing assembly by
confirming the handlebar display
is blank. (If power is on, press
and hold the power buton until
the display shuts of.)
3. Find the stem faceplate and the
four, 4mm stem bolts located in
the parts box.

are tight against the bike stem.
5. While holding the bars against
the stem, place the faceplate
on the opposite side of the
handlebars and loosely thread
the four, 4mm bolts into the four
holes on the stem (two above
the handlebars and two below).
6. Move to the back of the bike and
slide the cardboard wheel block
of the rear wheel, then put the
kickstand down.
7. Move to the front of the bike and

8. Grab the torque wrench from the
parts box.
9. Use the positioning guide sticker
to center the handlebars. When
looking at the bike from the front,
the sticker should be just to the
let of the stem and the “Center”
mark should be in-line with the
gap between the stem and
faceplate. No part of the sticker
should be under the stem.
10. If you prefer the handlebars to be
a bit closer or a bit farther away,
you can rotate them forward or
backward to the desired position,
using the face of the stem and
the positioning guide sticker as
reference.
11. Once the handlebars are in the
desired position, turn the two
top faceplate bolts clockwise,
tightening them just until the
rubber O-ring makes contact
with both the stem and stem
faceplate.

Congratulations!
Your New Charge Bike is Now Assembled
Before going for your first ride, review this assembly
checklist and the pre-ride checklist in your Charge
Bicycle Owner’s Manual
• Remove any remaining packaging material
• Check tire pressure – Tires must be inflated to the recommended
pressure (See Section TECHINICAL INFORMATION: Tires and Tubes in
your Charge Bicycle Owner’s Manual).
• Check brakes are working properly – Check that the lever feels
firm and doesn’t move too close to the handlebar grip. With any disc
brakes, the brake pads must make firm contact with the rotor without
the brake levers hiting the handlebar grip (See Section TECHINICAL
INFORMATION:Brakes in your Charge Bicycle Owner’s Manual).
• Is your stem securely fastened? Twist the handlebars firmly from
side to side while holding the front wheel between your knees. The
stem must not move in the steering tube (See SectionADJUSTMENT
INSTRUCTIONS: Adjustable Stem Instructions in your Charge Bicycle
Owner’s Manual).
• Is your seatpost securely fastened? Using the seat for leverage, twist
the seatpost. The seatpost must not move in the seat tube (See Section
ADJUSTMENT INSTRUCTIONS: Saddle/Seatpost in your Charge Bicycle
Owner’s Manual).
• Are your wheels properly fastened? Be sure to read the section on
proper wheel installation (See Section TECHNICAL INFORMATION:
Wheels in your Charge Bicycle Owner’s Manual).
• Ensure the fender stays are atached and fenders are not rubbing
on tires.
• Make sure your headlight is upright and pointing forward
• Power up the bike – Press and hold the power buton on the display or
the batery pack (marked with the [power symbol]) to power on the bike.
The LCD display will come to life.
• Verify batery charge – The Charge display will not only tell you how
much batery power is let as a percentage, but will also estimate range
in miles/km, so you can always be sure you have enough power to get
you where you’re going… and back again!

18
1. Turn Batery Power on: Press
the switch located on the
batery to the ON (-) position.
NOTE: This switch can be let
in the ON position at all times,
except when removing the
batery from the bike. Leaving
the batery switch ON allows
you to control the bike’s on / of
status from the display on the
handlebars.
2. Turn the Display on: Find the
power buton on the backside
of the handlebar display. Press
and hold the buton until the
display comes on or goes of
(about 2 seconds).
1. Shiting Gears: The Comfort is
also equipped with a 7-speed
manual shiter, so you can shit
gears just as you would on a
regular bike. Simply twist the
gear shiter on the handlebar
to select a gear – the lower the
number, the easier it is to pedal.

1. The Charge Comfort 2 is
equipped with Electric Assist,
Throtle and Walk Assistance
Mode. Choose your level of
electric assist from the display
by pressing the +/- butons: +
moves you to a higher level of
assist; - reduces the assist level.
The display will register the level
of assist: 1 = the lowest assist
level; 5 = the most assistance.
When the batery reaches 25%
- 30% of life remaining, the
system will enter a power-saver
mode, which will disable the
throtle and limit the level of
assist being provided in order
to maximize eficiency.
Level of assistance provided will
continue to decline as batery
charge is further depleted.
Once recharged, system will
return to full assist and throtle
function.
2. Using the Throtle: When you
don’t want to pedal, you can
use the thumb throtle on the
let-hand grip. Pressing down
with your thumb accelerates
the bike. Release to stop assist.
For safety reasons, the bike
must be moving forward at 1
mph or greater for the throtle
to engage. This is to prevent
accidentally engaging the
throtle and losing control of
the bicycle.
3. Using Walk Assistance Mode:
Walk assist mode propels the
bike forward at 2 mph making it
easier for you to move your bike
when you’re not riding.
Press and hold the “-” buton
on display. The “insert icon” will
display and the bike will begin
rolling forward. To disengage
Walk Assistance, release the “-”
buton.
