Congratulations on the purchase of your eZee bike. You’re
one step closer in realizing a whole new way of commuting that is
fast, fun and friendly to the environment.
The hub motor is brushless and uses a technology called
Pulse Wave Modulation control, so that its not subject to wear like
a regular DC motor. Planetary reduction gears incorporated into its
hub gives it a very strong torque, working in unison with your leg
power to atten out those hills and to overcome headwinds.
Under normal cruising conditions (26 kmh, 16 mph), the motor draws about 5 amps at 140 watts with 5 Nm torque and has an
efciency about 80%. Its electric consumption is about 1.0 kwH for
100 km / 62 miles in ebike mode - even less energy than the food
you would consume riding by leg power alone. Making it by far the
most efcient vehicle ever made.
While the eZee pledge to quality means our components are
high value and reliable. Its your part to understand safety implications and the possible risks of cycling. So please take some time and
read this manual. It explains the bike in detail, how to take care of it,
so that you can enjoy using the bike for many years to come.

Legal Regulations
EU regulations state that your vehicle is an Electric Powered
Assist Cycle (EPAC) when the following conditions are met.
[ EU directive 2002/24/EC Chapter 1 Article 1 1(h) ]
“Cycles with pedal assistance which are equipped with an
auxiliary electric motor having a maximum continuous rated power
of 0.25 kW, of which the output is progressively reduced and nally
cut off as the vehicle reaches a speed of 25 km/h or if the cyclist
stops pedaling.”
With EU compliant conguration, the power assist of an eZee
bike only functions while the rider is pedalling. The means of controlling the assistance is provided with either a dial or throttle system.
USA regulations allow a power assisted maximum speed of
20 mph. eZee bike made for the USA has a motor speed of 250 rpm
for a 20 mph top speed and a maximum rated power of 700 watts.
The power assist can function without the aid of pedalling, however
there’s nothing to stop you from doing so. Putting in some effort will
greatly increase the mileage you get from your battery.
This means you do not require a license or moped certicate,
there is no age limit and you can take cycling paths. It conforms to
regulations of normal bicycles. Legal requirements concerning insur-
ance of your bicycle may differ, so do nd out about the rules and
regulations in your country.

Sometimes after temporary disconnection, the charging status light may give a false green reading. To verify that your battery
is fully charged, switch the charger off, wait for the charger lights
to go out and switch it back on again. The charging status light
should quickly return from amber to green, when the battery is fully
charged.
The battery may be also charged on the bicycle, do make
sure that the bicycle is switched off so as to not waste electricity.
If the battery refuses to accept a charge, refer your eZee
dealer for more information.
Battery charging is automatically regulated, there is no
danger of overcharging. It is advised that you disconnect the
battery and switch the charger off as soon as the charging process
is completed.
Do not charge the battery in wet conditions.
Never allow children to play with the battery or charger.
Do not leave your battery in a fully discharge state for long
periods of time. The battery will continue to self-discharge,
resulting in damage.

How eZeebike works
Your rst ride Before you wheel your bike out into the world,
we recommend you practice handling the bike in a safe area away
from obstructions and trafc. The motor may look small, but it’s
powerful! You’ll be riding faster than you think.
Turn the key to the ‘ON’ position. A red LED
will illuminate below the key socket. If the light
ashes, read the Troubleshooting section of
this manual. If it shines steadily, you’re ready
for the next step.
EPAC / Pedelec As you pedal, rotation on the crank is picked
up by a sensor in the bottom bracket. This allows the drive system
to be engaged. A twist of the throttle then provides power-ondemand, reducing the pedalling effort required.
E-Bike The motor runs as soon as you turn the
throttle. Ensure that you are seated and ready to ride off before
you use the throttle. You may toggle the throttle on and off with the
switch located on it.
In E-bike mode, the range of your bike will be approximately 40
kms (25 miles). The hillier the terrain, the less you pedal, shortens
your range. While EPAC, judicious use of gears, power assistance
all contributes to increasing the mileage you can get out of your
ride. 40 - 60 kms (25 - 40 miles).
16
Page 17

How eZeebike works
Variable Power Assist (VPA) In lieu of a throttle, you may
have received or chosen a potentiometer dial. This set-up is only
compatible with EPAC mode eZeebikes.
The dial settings from 0 - 8 correspond accordingly to the level of
continous power assistance acheived by the motor during
pedalling. The level of assistance remains the same throughout
regardless of road conditions until you re-set the dial to another
position. This is especially useful for long treks or when you do not
wish to fuss about with a more sensitive throttle.
You can always choose to ride your bicycle as an ordinary bicycle.
Battery level gauge When riding a fully charged
bicycle, the battery level gauge shows ‘green’. Powerful
acceleration or uphill riding causes the battery voltage to drop and
may bring the level gauge to ‘amber’ or even ‘red’ (in the cases of
very steep hills).
As you continue to cycle and the battery power drops, the level
gauge will correspond to the state of charge remaining. When it re-
mains in ‘amber’ and dips into ‘red’, you have approximately a 1/3
of the charge left. Best to recharge the battery soon.
To prevent the battery from deep discharge, the controller has a
low voltage protection cut-off set at 30.0 V. You may reboot the
bicycle if it cuts off however,
‘Pulsing’, or straining any capacity left in the battery will
deteoriate its quality fairly quickly. Charge often!

How eZeebike works
Lighting system eZee bikes features wide angle high
performance reectors at the front, sides and rear. Front and rear
LED lights are powered by the main battery, electrical consumption
is negligible, be safe, use them often.
Lock When parking your bicycle, turning the key to
the ‘OFF’ position and removing it will shut the system off and lock
the battery in place. Use a chain lock to further secure your bicycle
when necessary. We also recommend you insure your bike against
theft. Consult your eZee dealer or LBS for more information.
Central support stand This spring loaded stand supports your
eZeebike straight up. Use your feet to depress the stand
downwards and pull the bike in reverse. Ensure the stand is rmly
rested on the ground before leaving the bike.
Do not sit on the bike with the stand parked. The central
support stand is made of aluminum alloy and meant to only take
the weight of the bicycle and not with the rider on it.
Luggage rack The luggage rack provided comes equipped
with a spring loaded catch and elastic strap. If you plan to carry
luggage on the rear, make sure everything is securely fastened
and clear from the rear wheel. There are many useful accessories
that can be tted on the rear rack, from panniers to child seats. Do
however, take note that the load limit is 25 kgs

Maintenance
Maintaining your bicycle ensures you’ll get the most out of
every ride and out of the entire life of your eZee bike. How much of
your bike’s maintenance you can do yourself will depend on your
knowledge, skill, experience and whether you have the necessary
tools for the job.
Learning from available cycling literature and joining cycling
communities can be an enjoyable way of improving your skill and
knowledge about maintaining bicycles. Beyond this manual, it is
good to consult your LBS and eZee dealer for advice regularly.
Before every ride Mechanical safety checks, use a fully charged
battery, visual inspection for damages.
Every 150kms (100 miles) Clean the bike, incl. chain rings and
sprocket. Clean and lightly oil the chain and gears.
Every 20 - 30 hours of riding Squeeze the brakes and rock the
bike to check for any looseness with each forward of backward
movement. If the headset is loose, have your dealer check it.
Lift the front wheel and rotate handlebars to check for tightness of
steering, it may be necessary to lubricate ball bearings.
Check and recalibrate the brakes, replace if worn out.
Squeeze spokes in adjoining pairs between your thumb and index
nger. They all should have the same tension. Have your dealer
respoke or true the wheel if necessary.
Check cables for rust, kinks and fraying, have your dealer replace
them if necessary.
<
Page 20
Maintenance
Repairing a punctured tyre If you have a punctured tyre, we
recommend that you get a specialist to carry out the repairs. You
can always of course consult a specialist and carry out the repairs
on your own.
As the rear wheel contains the hub motor, there are additional
steps in the case you require the entire wheel to be removed from
the bike. Located on the underside of the bike, unplug the wires
than run from the motor to controller. There should be 1 x 6 pin
connection and 3 colour coded wire connections (Blue, Yellow,
Green). Unplug these before proceeding to remove the front wheel.
Be mindful of the tightening assembly sequence of washers, nuts
and spacers.
Hub motor and general inspection
After 5,000 kms (3,000 miles) of cycling. We recommend you
arrange to have a thorough inspection of your bicycle by an eZee
dealer. This includes opening up the hub motor to inspect and
lubricate the gears.
Electronic self-diagnostic system
When the bicycle is functioning normally, the red LED that is
situated by the controller is lit continually.
In the case of an electronic malfunction, the controller comes
programmed with diagnostic capabilities to determine where the
fault lies. The red LED will emit a series of blinks, count them and
refer to the table below for its explanation and solutions.

The faults listed may not cover every possible failure. In the event of
moisture or water entering the controller, haphazard signals might
appear. We’ve designed the eZeebike to repel water as much as
possible, encapsulating circuit boards with silicone resins and connections with silicone grease.
Since this manual simply cannot cover every detail that
might occur during the lifetime of your product. Check our websites
and dealers website routinely for updates, or contact us directly for
more detailed questions you might have.
Serial Numbers Record the serial numbers found on your
motor, frame, controller, charger and battery here for reference.
This are important datas for us to understand and troubleshoot
