OPERATION OF YOUR ELECTRIC BIKE

Your e‐bike is driven by a motor embedded in the hub (centre) of the rear wheel. The motor is powered by a
battery. The amount of power delivered to the motor, and hence the accelerating force on the e‐bike, is controlled
by you.

There are two systems to activate the motor: Throttle and Pedal Assist.

The throttle can be twisted by hand and activates the motor (Figure C1).

In Pedal Assist mode (Figure C2), the motor is triggered when you pedal forward, and power assist will stop when
you stop pedaling. In other words, power assist happens as long as you pedal. You don’t need to pedal hard. All you
need is to apply a light force to the pedals continuously to maintain continuous rotation. When you apply one of the
brakes, power‐assist will automatically stop, allowing the e‐bike to slow down or stop. Power assist will turn itself
off before the e‐bike has reached the maximum speed of approximately 25 km/h

You should use the gear shifter at the handlebar to set the gears appropriately according to road conditions and
pedal as usual. Please refer to relevant section in this manual how to use gears.

Note that the Battery level indicators on the display (Figure C2, 5) will only show an estimate of the battery charge
level when power is not being drawn from the battery (bike standing still). While using motor assistance voltage will
decrease.

Figure C1:

The

twist‐and‐go throttle (2)

is located on the right hand side of the

handlebar, next to the

handle‐grip (3)

. Push the

red button (1)

IN to switch

the throttle on. Push the red button (1) again, so that it moves OUT to disable
throttle.
Grabbing the throttle with your right index finger and thumb wrapped around
it and twisting it down in the direction of the white arrow will activate the
motor and the ebike will move forward. The twist acceleration is gradual: Twist
it down only a little bit for moderate acceleration. Twist it down all the way for
maximum acceleration. The throttle will accelerate the bike to a maximum
speed of about 6 km/h (walking speed). If your throttle overrides the pedal
assist system meaning if you twist the throttle you can only go 6km/h, even if
you use pedal assist, then release throttle to use the pedal assist system.
The throttle can be unlocked to about 25 km/h for use on private property. If
the throttle is unlocked the bike must not be ridden on public roads. Please
refer to the relevant section of this manual how to unlock the throttle.

WARNING! 

Only switch throttle ON if you intend to ride the bike. Always switch throttle and bike OFF when walking 

next to bike and pushing the bike to prevent accidental acceleration. Always be ready to press 

brake lever (4)

to stop 

bike.

The display panel (Figure C2)

controls a number of

features on your ebike.

WARNING!

Only switch Pedal Assist ON if you intend to

ride the bike. To disable Pedal Assist push the “‐” button
(8) until all three pedal assist lights (9) are off. Do not
pedal when turning! Always switch bike and Pedal assist
OFF when walking next to bike and pushing the bike to
prevent accidental acceleration. Always be ready to
press

brake lever (Figure C1, 4)

to stop bike

.

‐Switch bike ON

: switch battery ON (refer to relevant

section in this manual). Voltage display: Four red lights
(Figure C2, 5) will light up if the battery is full. When the
battery discharges less lights will show as the battery
voltage decreases. The voltage will drop while the bike
is used. Stop the bike to read voltage. Voltage reading is
just and estimate and approximate. Voltage may not
drop in a linear fashion. Check battery power by pushing
the white button on top of the battery. Refer to
relevant section in this manual.

‐Switch bike OFF

by turning the key on the battery into

the OFF position. Always switch bike OFF if it is not
used.

‐Turn on the front and rear light of bike:

push the lights

‐ To activate “Pedal Assist”

push the “+” button (7)

to increase the power and speed. Push the “‐”
button (8) briefly to decrease the power and speed.
“Pedal assist” means that the motor will be
activated when you start pedalling and the bike will
move forward with motor assistance while you are
pedalling. The three pedal assist LEDs (9) show the
level of pedal assist: No red light: No pedal assist. 1
red light: LOW pedal assist. 2 red lights MEDIUM
Pedal assist. 3 red lights: HIGH Pedal assist. At lower
assistance levels the motor will accelerate to lower
speeds. At maximum assistance the motor will
accelerate to approximately 25km/h.
