Charging the Battery
The Juiced U500 V3 features a high-capacity Lithium Ion
rechargeable battery. Charge the battery fully before your first
use. The charger that came with your U500 recognizes the
battery pack’s initial charge and will automatically cease charging
when the battery is fully charged; don’t be shy about topping off
your battery before a long trip!
•Be sure the bike is powered off.
•Plug the 4-pin plug into the charger port at the front of the battery
pack. It can only be inserted one way, so if it plugs in, you’ve
got it right.
•An amber light on the charger indicates that the battery is charging.
•Charging takes between 1 and 6 hours, depending on battery size
and initial charge level.
•When the pack is fully charged, the charger’s light will change from
amber to green and automatically stop charging.
Notice: The
charger can
become warm
during charging.
Do not place
anything over the
charger while it is
charging. Do not
use the charger
in wet areas.

Turning the bicycle ON and OFF
The electric bicycle can be ridden like a normal bicycle with the
power turned ON or OFF. However the throttle will be active only
if the power is turned on.
•Locate the power switch on the front face of the battery.
•Flip the power switch to the "ON" position.
•The power button will illuminate with a green light
•The lights on the display panel will illuminate, giving an indication of
the battery’s charge level.
•The bike can now ride on battery power alone.
•Power should be turned off after each ride to avoid draining the
battery.

Using the twist throttle
The motor speed is controlled with a twist throttle similar to a
motorcycle. The farther you twist the throttle backwards, the faster
the bike will travel.
•Sit with a comfortable position on the bicycle's seat.
•Slowly turn the throttle backwards towards you.
•The front wheel will began turning and the bike will move forward.
•You can pedal along with the motor to increase the riding range of the
battery. However pedaling will not directly charge the battery.

Using the Brakes
The bike comes equipped with front and rear Tektro Dorado
hydraulic disc brakes; the very best available for e-bikes. The
brakes’ main function is to slow down or to stop the bicycle.
•The brake on the front wheel is controlled by the lever on the left-
hand side of the handlebar
•The brake on the rear wheel is controlled by the lever on the right-
hand side of the handlebar
•The front brake provides the majority of the bicycle's stopping
capability
•When slowing down on slippery surfaces, use the rear brake first
before applying the front brake
•A signal wire from each brake lever automatically cuts power to the
motor when either brake is being used. This prevents undue wear to
the electric motor

Shifting the gears
Your U500 V3 comes equipped with a 3-speed internally geared
hub. 1st gear is useful for starting off from a stop or when riding
slowly or climbing steep hills. 3rd is most effective when riding at
speed. 2nd fits into the space between. The internally-geared hub
doesn’t require pedaling while changing gears; you can stop at a
red light in 3rd, switch to 1st while you’re waiting for the green, and
take off in 1st with no clickety-clack, no slow-at-first start, and no
fear of the chain falling off.
•The shifter is located on the left side of the handlebar.
•Twist the shifter completely back to enter the first gear.
•Twist the shifter forward to enter 2nd and 3rd gears.
When starting and going up hills, use the 1st gear.#
When pedaling at higher speeds, use the 2nd and 3rd gears.
Changing gears does not require that the bike be powered by the
battery. The gear shifting system and motor are entirely separate
and neither affects the other’s performance. Both work toward the
goal of propelling the bike, of course, and their contributions are
additive.
Notice: Twist shifters are normally mounted on the right side of the handlebars. On
electric bicycles with right-side twist throttles, the shifter must be mounted on the left
and the numbers may appear inverted. !

Using the cruise control
The cruise control system can be used to maintain a constant
speed. It works similar to a cruise control in an automobile. The
cruise control will deactivate if the brakes are applied, if the
throttle is moved, or if the CRUISE button pushed again. The
bicycle will return to normal operation.
How to use the cruise control feature:
•Use the throttle (with or without pedaling) to attain your desired speed
•Holding the throttle in a fixed position, push the “CRUISE" button
•The LED will illuminate to indicate that the bike is in cruise mode
•Let the throttle return to its initial position (i.e., let go of it)
•The bike will now maintain a constant speed until:
1. The brakes are applied, or
2. The throttle is applied anew, or
3. The CRUISE button is again pressed, or
4. The battery runs down completely

How to read the battery level
There are 4 LED lights on the display panel which will give you an
indication of the batteryʼs voltage. Because the battery gauge
measures voltage, only an approximate estimation of the battery's
state can be obtained. The battery’s voltage can vary greatly
depending on a variety of conditions.
The voltage will decrease temporarily when using the throttle. It may
drop to only 1 light when going uphill regardless of the charge state.
This is normal operation. The voltage will be lower if the battery has
been in a cold environment.
To more accurately read the batteryʼs charge state, let off the throttle.
The display lights will stabilize after 1 second to give an indication of
the battery’s level.
Use this guideline to estimate the battery's charge level:

Let off the throttle to read the Lights !!!! 4 Lights
The battery is between 80% and 100% charged.
!!!!3 Lights!
The battery is between 40% and 80% charged. Speed will feel reduced.
!!!! 2 Lights!
The battery level is low and should be recharged soon.
!!!! 1 Light!
Stop using the throttle, recharge the battery pack.

Understanding Battery Range
All electric bicycles have a riding range that can vary greatly
depending on how it is ridden, terrain, tire pressure, temperature,
payload and wind. After a few rides, you will get a sense of the
electric bicycle’s range capability.
Factors that will decrease your range:
•Rapid accelerations using the motor • Uphill riding
•Heavy payloads
•Headwinds
•Under-inflated tires
•Extreme hot or cold weather
How to increase your range:
•Start by pedaling instead of only using the motor
•Avoid rapidly accelerating using the throttle
•Pedaling to help the motor up steep hills
•Reduce your average speed and pedal along with the motor
•Reduce payload weight
•Properly inflating your tires between 40-50 psi
•Coast to a stop and avoid rapid decelerations
#
Notice: Riding downhill or pedaling when not using the throttle will not recharge
the battery pack. Do not over-inflate the tires.
