EWheels has introduced yet another new
specially designed folding power assisted
mountain bicycle, The “EW-475 ”. The EW475 offers a comfortable and affordable
alternative when normal cycling becomes too
strenuous or the daily trip too long.
The EW-475 Electric Folding Mountain Bike
provides extra energy without much effort
along with the ability to “fold” the bike for
easier transportation or storage making it
unique in design and use.
Cycling is a sport that fits easily into anyone’s
daily routine. Utilizing the bikes optional
power assisted mode, you can cycle to work,
cycle with the children to school, to the mall,
to visit friends for coffee or just to enjoy the
fresh air and nature without the effort of a
traditional bike.
Like any sport, electric bike carries the risk of injury and
damage. By choosing to ride the EW-475, you assume
all responsibility for these risks. Thus, you need to
know and practice the rules of safe and responsible
Safety Basics: Do’s and Don’ts
The Do’s
o Always conduct a Safety Check before you ride your
EW-475. Be thoroughly familiar with the controls of
your EW-475.
o Always wear an approved helmet when riding your
EW-475. Follow the helmet manufacturer’s instructions
for fit, use and care of your helmet.
o Always keep body parts and other objects away from
the spinning wheels of your EW-475.
o Always wear shoes that will stay on your feet and will
stay on the pedals.
o Wear bright, visible clothing that is not so loose that it
can catch on moving parts of the EW-475 or objects
at the side of the road or trail.
o Think about your speed, and keep your speed
consistent with safe operating conditions.
The Don’ts
o Never 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 EW-475, causing you to lose control.
o Never carry a passenger. The maximum carrying
capacity is 350 Lbs.
o Never ride barefoot or wearing sandals.
o Don’t jump with your EW-475. It puts great stress on
everything from frame and forks to drive train. Riders
who insist on jumping their EW-475 risk serious
damage to their EW-475 as well as to themselves.
o Never carry anything which obstructs your vision or
your complete control of the EW-475 or which could
become entangled in the moving parts of the EW475.
o Never hitch a ride by holding on to another vehicle.
o Never ride your EW-475 while under the influence of
alcohol or drugs.
o If 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.
o Never allow children to ride. Never allow others to ride
without reading and understanding these instructions.
Operating Reminders and Suggestions
o Review all instructions carefully before riding the EW475.
o Follow 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.
o Ride predictably and in a straight line. Never ride
against traffic.
o Ride defensively. To other road users, you may be
hard to see.
o Concentrate on the path ahead. Avoid potholes,
gravel, dirt, wet road, oil, curbs, speed bumps, drain
grates and other obstacles.
o Be alert for unexpected events, such as opening car
doors or cars backing out of concealed driveways.
o Be extra careful at intersections and when preparing
to pass other vehicles.
o Don'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.
o Maintain 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 EW-475 is equipped with correctly
positioned and securely mounted reflectors. Make sure
your clothing or cargo does not obstruct a reflector or
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.
Other Reminder
The battery does NOT require deep discharging. If your
EW-475 is put into storage, re-charge its battery at least
once every 90 days.
Do not store your EW-475 in direct sunlight for an
extended time.
Store your EW-475 in a dry place. Exposing your EW475 to rain, snow, or other precipitation may result in

Pre-Ride Check
1) Be sure the tires have enough air. A low tire
pressure risk rim pinching (tube failure) and lowers
your range (distance per charge).
2) Be sure the battery is fully charged. Riding on a
low state-of-charge will reduce range, and can
damage the battery.
3) Verify the proper adjustment and function of the
4) Make sure the EW-475 is in good mechanical
order. Visually inspect and hand-check the vehicle,
and snug any loose bolts, screws, or other
5) With the EW-475 visually inspected, turn the key
switch and apply the throttle, to verify the motor’s
smooth operation. Apply the brake to stop the
motor. Verify that the throttle is inoperative when
either brake is applied.

Battery Care and Maintenance
What to Expect of Your Batteries
The battery is a sealed lithium type. With normal use, it
can last for well over 400 charge/discharge cycles.
Know that normal use should mean partial, and not
complete discharging. If you employ “shallow” discharge
cycles, using less than 30% of battery’s capacity, the
battery can achieve up to 600 charge/discharge cycles.
Thus, it is good to charge the battery after each ride. A
partial discharge will require less time on the chargers.
What to Expect, Realistically
The battery can keep its performance for about 400
charge/discharge cycles, with high current and deep
(80%) discharging. The storage capacity of the battery
will decline after 200 times recharging. If you re-charge
the battery before it is exhausted, you dramatically
extend the battery’s cycle life.
In Summary
Always try to recharge the Battery Pack within 24 hours
after use to maximize battery cycle life and prevent
What’s Inside Your EW-475 Battery
The Battery is composed of four 3.7 Volt, 10 Amp-hour
capacity batteries, in series, for a total capacity of 36V,
10 Ah.
The component batteries are a standard, commercially
available size. Keep this in mind, however, should you
choose to service your battery.
1) The batteries are soldered into place. Replacing
batteries will require soldering equipment and
2) Batteries can be extremely dangerous. If allowed
to short-circuit, they can cause burns, create
blinding arcs, or explode, causing serious injury. If
you accept this risk, work slowly, and exercise
utmost care! Work with only one wire at one time.
Battery Trouble
Should a battery ever leak, do not touch the battery
liquid. If you are exposed to the solution, flush the
affected area with water. If you must handle the battery,
wear disposable gloves.
Replace the battery if there are leaks, visible breaks or
Dispose of used batteries by taking them to a recycling
center, or according to state and local laws.
Battery Temperature Sensitivity
Ambient temperature will affect almost every kind of
battery. Usually, the battery shows good discharging
capability at higher air temperature. When the air
temperature is under 0 ºF, the battery power will decline
more than one third. So it is natural that the EW-475 will
not reach its normal mileage in winter or in cold weather.
When the air temperature is up to 68 ºF, the EW-475 will
achieve its normal range capability.
When the ambient temperature is over 110 ºF (as when
exposed to summer sunshine for a long period), batteries
and other electric components usually run in an abnormal
Battery Charging
Be sure to charge the battery completely if you will not
use it for a long period. Ideally, you should charge it
every 20 days. Even a healthy battery will discharge itself
slowly. Even with its power off, the EW-475 Battery
state-of-charge will decline gradually over time.
Remember to fully charge the battery before your first
ride. The battery may be low when you receive your new
1) While charging the Battery, keep the key switch
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 EW-475 (the charger port islocated 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 supplied
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.
Do not place the battery near heat or fire. Do not expose
the chargers to water.
Front and Rear Tires
The changing method of the front tire is the same as
common bicycle. It is more complex to change the rear
tire because of the motor and brake assemblies, and
associated wiring and cabling. If you are not comfortable
with undertaking this operation, you can ask your
servicing dealer or mechanic for assistance.
You should inspect and maintain your EW-475 and
lubricate the mechanical power transmission components.
The brake cables may also need lubrication
Lubricate the brake cables with silicone or graphite
lubricant. Maintenance period: one month.
Lubricate the fork Shock Absorber tube, axle rim, and the
axle ball bearing with SH/T0386 lubricant, bicycle or
lithium grease. Maintenance period: one year.
1) Never wash the bike using high-pressure water, as
it will cause damage to the electric bike.
2) Never use lubricant to clean the metal parts of the
bike and never apply lubricant to the drum brake
and the tire.
Scheduled Maintenance
EW-475 should be checked from time to time. Refer to
the maintenance schedule in the following chart:
Check ●
Bolts, nuts, screws etc-to ensure that
nothing is loose.
Tire pressure-to ensure good tire
Drive equipment-to ensure good
position; not too loose, nor too tight.
Brake pads-to ensure it is not worn
Wheel rim- to ensure it is not distorted.
Steering Linkage- to ensure it is not
Brake-to ensure it is working properly.
Throttle- to ensure that it is working
Steering system-to ensure operation is
