5. Adjust the brakes. The distance between the brake shoe and the rim should
not be more than 2mm. If the brake pad becomes worn, it should be
replaced immediately. Read below section on brake testing.
Brake Testing
Squeeze the brake levers. The brake levers should be easy for you to reach,
and engage the brakes completely when pulled in. You should not be able to
pull the brake lever in until it touches the handlebar or grip. Test the brakes
and the brake lever adjustment; you should be able to comfortably control
your brakes. If the brake is adjusted too loose, the extra play will cause
insufficient braking power. The play is properly adjusted if the brake pads
meet the rim fully when the brake lever is pulled one-third of the way.
If you have any questions about the operation or adjusting the brakes, contact the
IES Service Department at 1-866-726-6856.
Local bicycle shops are usually willing to assemble bicycles for a fee. They will often
check a bicycle for safety at no charge.
If you have any questions please call the IES Service Department at 1-866-726-
6856.

OPERATING INSTRUCTIONS
Before You Ride
Make sure all parts, components and accessories are in good working order. Check all
fittings and be sure that they are tight and secure. Inspect your bike completely.
Batteries
CAUTION: DO NOT ATTEMPT TO OPEN OR TAMPER WITH THE
BATTERY IN ANY WAY. DOING SO MAY CAUSE CHEMICAL,
ELECTRICAL AND/OR FIRE HAZARDS.
Batteries that lay dormant for an extended period of time will lose their ability
to accept charge. Please make sure you ride and recharge your bike periodically
to prevent this from happening. Charge the batteries every two months, even if
the vehicle is not being used.
You should recharge the batteries after every use for optimum performance and
battery life. One cycle is one complete charge and discharge of the battery. You
will need to replace your batteries when they no longer hold a sufficient charge.
RECHARGING THE BATTERIES
It is important that you charge your batteries after every use. This will extend
the total life of your battery. Once the charger has indicated that the battery is fully
charged, unplug the power source from the bicycle and from the electrical outlet and
store in a cool (59°- 86°F or 15°- 30°C), dry (10% - 70% humidity) place. WARNING:
Do not leave the battery charger plugged in for long periods of time. This can
damage the batteries.
The battery does not have to be removed from the bike for recharging. If you choose to
remove the battery box from the bicycle frame during recharging, exercise care to avoid
damaging the charging cables.
To charge your batteries:
1. Turn the on/off switch to the “off” position.
2. Insert the charger’s plug into the battery box charging port.
3. Plug the battery charger into the wall outlet.
4. Turn the charger on. The first time you charge the battery, you must charge for a
minimum of 10 hours, but do not charge for more than 20 hours. After the initial
battery charge, your Centaur battery can be completely charged in 4 hours.
5. The charger will take up to 4 hours to recharge the battery completely. When the
green light appears the battery is sufficiently charged.
6. Do not charge for more than 4 hours (after the initial charge) to avoid
overcharging and damaging the battery, especially in hot weather.
7. Charge the bike in a dry and clean place. Keep the charger dry and clean. The
charger will become warm during charging.

OPERATING INSTRUCTIONS – Recharging the battery (continued)
PRECAUTIONS WHILE RECHARGING THE BATTERY
1. Using your power source incorrectly or leaving the power source
connected to the bicycle and plugged into an AC power source
for extended periods of time can result in a fire.
2. Always use your charger as instructed.
3. Do not use any other charger than the one that came with your Centaur.
4. Avoid any contact with water when recharging your battery. If a plug or
socket should get wet, dry it thoroughly before proceeding.
5. Do not recharge your battery in direct sunlight or in any very hot
environment.
6. Be sure to keep pets and small children away from the area where you are
recharging.
7. To avoid damage to the integrated charger, never subject it to intense
physical shock or constant vibration.

BICYCLE COMPONENTS
Wheels
Wheels should be centered in fork or dropouts. Whenever you hear any
irregular noise from the wheels or the brakes, the wheels should be checked
and repaired. Wheels should be checked regularly for spoke tightness and rim
alignment. Wheels should rotate smoothly without wobbling from side to side.
Check the bearing play of the hubs by lifting the bicycle and spinning the wheel.
The wheel should continue to spin for several turns and finally cease spinning.
To check the play of the hubs, try to move the rim from side to side between the
forks. During this test, no substantial play should exist. If you detect play or if
the wheel is difficult to turn, the hub bearings must be adjusted.
Please contact a local bicycle dealer to have the hub bearings adjusted or call
the IES Service Department at 1-866-726-6856.
Rims
The rims must be smooth and without cracks, breaks or bulges.
Spokes
Check spoke tension regularly. Approximately the same tension should be
applied to all spokes. If there is minor loosening of the spokes, you may tighten
the nipples, but it is recommended that you take the bicycle to a bicycle
mechanic. If you detect a loose spoke or if the rim has a side play of more than
4mm (1/8 inch), immediately have the wheel trued by a bicycle mechanic or
call our IES Service Department at 1-866-726-6856.
RIDING WITH LOOSE SPOKES MAY CAUSE THE WHEEL TO FAIL
Tires
Inflate your tires to the pressure embossed on the sidewall before the first use
of your new bike. The recommended tire pressure for the Centaur is 40-PSI.
Every time you ride, make sure that the tires are inflated according
to pressure indicated on tire sidewall. Improper tire pressure will cause
excessive wear, causing premature replacement. Low tire pressure will also
make riding more difficult. The tire should be properly seated in the rim and
the fitting of the tire bead and rim bead should be checked. If the tube is
pinched between the tire and the rim, it will fail when inflated. Ensure that the
tire is not cracked or unevenly worn. Check for bulges. Check that the valve is
straight in the rim. Irregular tires should be replaced immediately.

BICYCLE COMPONENTS (continued)
Handlebar and display
We have created and designed this handlebar assembly so that everything you
need is within easy reach and sight while riding. To adjust the height of your
handlebar, loosen the stem binder bolt by turning it counterclockwise 4 or 5
turns with your Allen wrench. Adjust the height position as desired, and
remember to align the stem with the wheel before retightening the stem bolt.
Make sure you cannot twist the handlebars after tightening.
CAUTION: LOOSE OR DAMAGED GRIPS ON YOUR HANDLEBARS
ARE DANGEROUS. IF YOUR GRIP COMES OFF, YOU COULD LOSE
CONTROL OF YOUR BICYCLE. A GRIP WITH THE END MISSING
CAN ALLOW HANDLEBARS TO SERIOUSLY INJURE A RIDER
DURING AN ACCIDENT. PLEASE CHECK THAT BOTH
HANDLEBAR ENDS ARE PLUGGED. BE SURE THAT YOUR GRIPS
ARE IN GOOD REPAIR AND SECURELY GLUED OR FASTENED TO
THE HANDLEBARS.
Brakes
Riding with brakes that are damaged, have worn brake shoes or cables, or are
on wheels that are in poor condition or damaged may result in losing control of
your bicycle. Wet weather detracts from brake performance. You will require
more distance to stop safely in the rain or on a wet or icy street. Check to be
sure the brake cables are not wrapped tightly, and are free of obstructions. It is
important to check that your brakes work properly before operating your
vehicle. Test before every use.
Power ON/OFF
Your Power On/Off switch is a key switch located on the right side of the bike
frame, beneath the handlebar assembly.

BICYCLE CARE
We recommend having your Centaur serviced once a year by a bicycle
mechanic for regular bicycle maintenance in order to ensure safety and keep
components in proper working order.
Throughout the year, there are simple steps you can take to inspect and
maintain your Centaur:
1. Every week or two, tighten all nuts and bolts. Check all hardware to see
that no parts are worn, damaged, or missing. Make certain that the frame
and fork alignment are true and that all components are seated in the right
position.
2. Clean the frame and all parts regularly with a moist cloth or sponge.
Remove the optional midpoint battery and turn off the power before
cleaning. Do not completely immerse the bicycle in water and avoid using
the hose and/or soaking the battery and motor area. Be sure to completely
dry bike with a soft towel to prevent rusting and corrosion. Your Colt is
water resistant, but not water-proof.
3. Reflectors should be kept clean, securely fastened and positioned for easy
visibility at night from the front, rear and side. Immediately replace any
damaged reflectors. ALWAYS USE A FRONT AND REAR LIGHT
WHEN RIDING AT NIGHT. Check your local regulations for specific
requirements.
4. Replace worn or damaged cables. Do not kink cables. Cables stretch with
use - adjust accordingly. Keep control cable lubricated.
5. Replace worn grips. Make sure they fit snugly.
6. Check the chain tension frequently and keep it adjusted.

SAFETY RESPONSIBILITY
Know the laws of your state. It is your responsibility to know and obey the laws of your
local area concerning the operation of an electric bicycle. In most cases, cyclists must
obey the same laws that apply to motorists. This may include the use of proper protective
equipment – in many states children and youths are required to wear helmets.
There are also some common sense rules to keep in mind as you are preparing to ride
and as you are riding.
1. Wear your helmet at all times. This is required by law in some states and is
an important precaution in all states. Always use a helmet that fits and is
approved for such use. Keep the chinstrap fastened. HELMETS CAN HELP
PREVENT HEAD INJURIES IN THE EVENT OF AN ACCIDENT.
2. Only one rider at a time. Riding double or carrying large objects that obstruct
your vision or interfere with your control of the vehicle can result in loss of
control.
3. Ride with traffic and obey all traffic laws.
4. Do not perform tricks or stunts. Maintain complete control, caution and a
reasonable speed at all times. This bicycle is not suited for stunt jumping,
competition or racing. Never allow other vehicles to tow the bicycle.
5. When riding at night or in inclement weather, always use lights that are bright
and in good working order. Use a clear light on the front and a blinking red light
on the back. Wear light colored and/or reflective clothing. Assume motorists are
unable to see you and ride in a very defensive, cautious manner.
6. Take special precautions when riding in the rain, ice or snow. Give yourself more
time and room to brake. Ride slower than normal in order to keep full control of
your bicycle. It is also difficult for motorists to see you when it is raining or
snowing; take care when riding in inclement weather.
7. Watch for cars pulling out in front of you and the sudden opening of car doors.
8. Give pedestrians the right of way and be sure to (bell, horn, voice, etc.) alert them
to your presence to avoid any type of collision.
