Safety Basics: Do’s and Don’ts
The Do’s
oAlways conduct a Safety Check before you ride your XB-490. Be thoroughly familiar with
the controls of your XB-490.
oAlways wear an approved helmet when riding your XB-490. Follow the helmet
manufacturer’s instructions for fit, use and care of your helmet.
oAlways keep body parts and other objects away from the spinning wheels of your XB-490.
oAlways wear shoes that will stay on your feet and will stay on the floorboard.
oWear bright, visible clothing that is not so loose that it can catch on moving parts of the
XB-490 or objects at the side of the road or trail.
oThink about your speed, and keep your speed consistent with safe operating conditions.
The Don’ts
oNever ride with headphones. They mask traffic sounds, distract you from concentrating on
your surroundings, and their wires can tangle in the moving parts of the XB-490, causing you
to lose control.
Never carry a passenger. The maximum carrying capacity is 350 lbs.
oNever ride barefoot or wearing sandals.
oDon’t jump with your XB-490. It puts great stress on everything from frame and forks to drive
train. Riders who insist on jumping their XB-490 risk serious damage to their XB-490 as
well as to themselves.
oNever carry anything which obstructs your vision or your complete control of the XB-490 or
which could become entangled in the moving parts of the XB-490.
oNever hitch a ride by holding on to another vehicle.
oNever ride your XB-490 while under the influence of alcohol or other drugs.
oIf possible, avoid riding in bad weather, when visibility is obscured, at dusk or in the dark, or
when you are very tired. Each of these conditions increases the risk of accident.
oNever allow children to ride. Never allow others to ride without reading and understanding
these instructions.
Operating Reminders and Suggestions
oReview all instructions carefully before riding the XB-490.
oFollow all rules and regulations in your area for operating a motorized bicycle. Obey the same
road laws as all other road vehicles, including yielding the right-of-way to pedestrians, and
stopping at red lights and stop signs.
oRide predictably and in a straight line. Never ride against traffic.
oRide defensively. To other road users, you may be hard to see.

5
oConcentrate on the path ahead. Avoid potholes, gravel, dirt, wet road, oil, curbs, speed
bumps, drain grates and other obstacles.
oBe alert for unexpected events, such as opening car doors or cars backing out of concealed
driveways.
oBe extra careful at intersections and when preparing to pass other vehicles.
oDon't carry packages or passengers that will interfere with your visibility or control of the
bike. Don't use items that may restrict your hearing.
oMaintain a comfortable stopping distance from all other riders, vehicles and objects. Safe
braking distance and forces are subject to the prevailing weather and road conditions.
Wet Weather Riding
Wet weather impairs traction, braking and visibility, both for the rider and for other vehicles
sharing the road. The risk of accident is dramatically increased in wet conditions. In wet
weather you need to take extra care. In wet conditions, the stopping power of your brakes (as
well as the brakes of other vehicles sharing the road) is dramatically reduced. This makes it
harder to control speed and easier to lose control. To make sure that you can slow down and
stop safely in wet conditions, apply your brakes earlier and more gradually than you would
under normal, dry conditions.
Decrease your riding speed, avoid sudden braking, and take corners with additional caution.
Keep in mind that there is a direct, but inverse, relationship between speed and controllability.
Be more visible on the road. Wear reflective clothing and use safety lights.
Potholes and slippery surfaces such as lane markings and train tracks all become more
hazardous when wet.
Night Riding
A rider is very difficult for motorists to see at dusk, at night, or at other times of poor visibility. If
you must ride under these conditions, check and be sure you comply with all local laws about
night riding; follow the Rules of the Road, and take the following precautions:
Make sure that your XB-490 is equipped with correctly positioned and securely mounted
reflectors. Make sure your clothing or cargo does not obstruct a reflector or light.
Wear light colored, reflective clothing and accessories, any reflective device or light source that
moves will help you get the attention of approaching motorists, pedestrians and other traffic.
Ride slowly. Avoid hazards, such as potholes and curbs.
Avoid areas of heavy traffic, dark areas, and roads with speed limit over 35 mph. If possible, ride
on routes already familiar to you.
Ride at night only if necessary. Slow down and use familiar roads with street lighting, if possible.

6
Other Important Reminders
The battery does NOT require deep discharging. If your XB-490 is put into storage, re-charge its
battery at least once every 30 days.
Do not store your XB-490 in direct sunlight for an extended time.
Store your XB-490 in a dry place. Exposing your XB-490 to rain, snow, or other precipitation may
result in damage.

Operation
Your new Electric Bicycle/scooter is a revolutionary new transport product using a sealed lead
acid batteries and a super high efficiency electric hub motor designed to ASSIST in the propulsion
of you and your bicycle. It is important to note the following riding guidelines to ensure you get
the best possible experience from your electric bicycle.
Riding tip checklist
When starting off from stand still, pedal bicycle up to speed then engage throttle for best
results.
On inclines pedaling will be required to maintain momentum.
Ensure Tires are fully inflated to 30-35 PSI for bikes.
Remember performance of the bike is directly related to weight of the rider and any
baggage/load together with the charge in the batteries.
Ensure batteries are fully charged prior to riding.
Charge overnight prior to riding the next day.
Never let the batteries go fully flat. This will reduce battery and bike performance.
Apply chain oil periodically and clean if dirty or gummed up using a degreaser then wipe
clean and apply bicycle chain oil.
If your bike is equipped with lights we recommend you ride with them switched on at all
times to increase visibility for you and other road users.
It’s important to start pedaling for a few revolutions THEN slowly turn the throttle control
and gradually bring on the power. This ensures the battery and motor is not overloaded.

Battery Care and Maintenance
Removing the battery box
Removing the battery is useful to transport the Bicycle to reduce lifting weight or to charge in a
location where the bicycle may not fit etc.
1. To remove the battery box from the bike, unlock the seat first and then open it,
see figure 1-1
figure1-1
2. unplug the battery. see figure 1-2, take out the battery box, see figure 1-3
figure 1-2 figure 1-3
Charging
figure 1-4
1. To charge the batteries insert power plug on the battery charger into power outlet
2．Connect to the battery-charging socket located under the seat, see the above picture

11
ONLY CONNECT THE BATTERY CHARGER LEAD TO THE BIKE. NEVER
CONNECTANY OTHER POWER SOURCE TO THE BIKE.
3. Charge for 4~8 hours then unplug from wall outlet
4. If the bike is ridden everyday or very frequently, longer battery life will result from a longer
charge period once per week for 10+hours
5. If the bike is ridden less frequently then a long charge each month will assist battery life.
6. Do not leave the battery with a small amount of charge in it always keep topped up
7. Charge after each use.
8. Red light= on charging
9. Green light= fully charged
1) While charging the Battery, keep the key switch OFF.
2) Verify that you are using the correct charger for your vehicle, and that the charger input
power is compatible the “house current” in your area.
3) Keep the charger and battery away from water to prevent electrical shock and shorting.
The charger is intended for indoor use only.
4) Plug the end of the charger’s cord into the socket of the adaptor first. Next connect the
adaptor to the XB-490 (the charger port in located below the front of the seat). Then plug
the chargers’AC cords into the wall outlet.
5) Read the charger label to learn about the charger indicator lights, and their meanings.
6) Generally, a short drive will require a short time to re-charge, and a long ride will require
a longer time. A complete (90%) discharge may require 6 hours to recharge. To
prevent electrolysis (battery fluid loss by hydrogen generation,) do not charge for longer
than eighteen hours.
Before riding the electric bike for the first time, you must charge the batteries for 4-6 hours using
the enclosed charger. To charge, pull the protective cover from the charging sockets. Then plug
the charger into the charging sockets, and plug the chargers into a wall outlet.
WARNING
