Names of all structural components

Assembly
Your Revvi arrives almost completely assembled, making it easy to
start riding. The only assembly required is to attach the handlebars.
All cables and controls already hooked up to the bike, so attaching
the handlebars is easy:
1. Using the 6mm Allen key attach the lower parts of the
handlebar clamps to the top of the forks. Do not tighten
until the handlebars are in place!
2. Place the handlebars into position in the lower clamps.
Take care to get the handlebars centered side so side, and
set in your desired upright position.
CAUTION Be careful not to lean the handlebars too far
forward or backward as this will affect the bike’s handling
and comfort of the ride.
3. Place the top parts of the clamps in position over the
handlebars and tighten the four bolts securely to 18-
26N.M. DO NOT OVERTIGHTEN.
4. Now tighten the two bolts holding the handlebar risers
to the forks to 18-26N.M. DO NOT OVERTIGHTEN.

Charge the battery
First, be sure that the toggle switch on the top of the “tank” is
switched to the off position.
Locate the battery charger port which is on the right side of the
bike and flip up the small round black protective cap. Under this
cap you will see a round connector with three small contact posts.
Note that there is a small locating spline at the bottom of the
connector.
On the round end of the battery charger cord, you will see a plug
that has three small holes a notch which fits into the connector on
the bike.
1. Plug the charger into a wall outlet. If the lights on the charger
do not light up. Check the power to the outlet. If necessary, try
a different outlet.
2. Turn the bikes power switch OFF before charging. Plug the
charger into the charger port on your Revvi.
3. The light on the charger should be red. You need to leave it on
charge until the light goes green. The green light indicates that
it is fully charged.
It is important to charge the battery fully before using it for the
first time.

OPERATING CONTROLS
To operate your Revvi you need to be able to operate the throttle,
brake and other controls without stopping to look at them. Please
study the image below carefully to become familiar with the
function and the location each control.

When operating your Revvi there are some key operating controls
and components that allow you to operate your bike.
Their location and operation information is shown below.
1.On/Off Switch 2.Throttle 3.Brake
ON/OFF SWITCH
The ON/OFF switch is conveniently located just
ahead of the driver and is equipped with a flip-
up cover. The cover, when closed also shuts off
the On/Off switch. The switch should be left in
the off position whenever the bike is not being
used to protect the charge that is in the
battery. You will know that the switch is on
when the charge indicator lights on the throttle
are lit.
THROTTLE
The throttle allows the rider to send power to
the motor and make the bike move forward.
The power and speed is variable due to the
twist-grip throttle mechanism.
DANGER When giving the throttle power,
twist it slowly at first to avoid sudden
acceleration
BRAKE
Your Revvi is equipped with a rear disc brake.
The brake lever is hand operated and is on the
left hand grip mounted to the handlebars.
Squeeze the brake carefully with increasing
force to stop the bike.
DANGER Applying the brakes too quickly can
cause the bike to skid and you may lose
control.

2-Stage Safety Speed Limiter
The Revvi is equipped with a special switch that reduces the speed
to accommodate younger, smaller riders. The switch is located
inside the battery case, under the battery in a hard to reach spot to
limit access by inquisitive smaller children.
NOTE: The 2-stage safety speed limiter switch is set at the factory
to the slower speed setting. To switch from slow speed to regular
speed, or vice-versa, follow the steps below.
1. Lift the front of the bikes up or lean the bike on its side.
2. These is a small hole in the bottom of the plastic covers that
protect the batteries. Reach through the hole with your finger
and flick the switch from “I" (slow speed) to “O” (fast speed).
3. Your Revvi is now set to its fastest setting. To return the bike to
the slow speed setting follow these steps but flick the switch
back to "I".

Balance wheels
Your Revvi bike includes a set of balance wheels as shown on the
structural components page. We recommend that you use these
balance wheels for any novice rider who has no previous riding
experience without them.
The balance wheels are easy and simple to fit:
1. Remove the extra nut supplied on each side of the rear axle.
CAUTION! Do not remove the nuts holding the rear axle in place!
2.Fit a balance wheel to each side of the rear axle.
3. Fix the balance wheels in place with the two nuts you removed
from the axle.
CAUTION! Please ensure the balance wheels are done up tight so
they cannot move whilst the bike is been ridden.

MAINTENANCE
Being an electric-powered vehicle, your Revvi is a relatively low
maintenance machine. However, it is important to properly care for
the unit to keep it operating properly and safely. Below are items
that you will need to care for on a regular basis.
STORE INSIDE, OUT OF THE WEATHER
WARNING IT IS EXTEREMELY IMPORTANT TO ALWAYS STORE YOUR
REVVI INDOORS AND OUT OF THE WEATHER. THE ELECTRICAL
SYSTEM IS COVERED BUT SHOULD NOT BE CONSIDERED SEALED.
WATER CAN CAUSE SERIOUS DAMAGE TO THE POWER TRAIN AND
CREATE A DANGEROUS SITUATION WATER DAMAGE WILL VOID
YOUR WARRANTY.
DRIVE CHAIN TENSION
The drive chain transmits power from the motor to the rear wheel.
To work properly it must be lubricated and properly tensioned at all
times.
Check the tension on the drive chain by moving it up and down
approximately halfway between the sprockets. There should be no
more than 1/2” vertical slack in the chain. If the chain seems too
loose, it may be in danger of coming off while riding.
To adjust the chain tension, follow the steps outlined below:
1. Be sure that the Revvi is parked on a flat level surface, is
switched off and leaning on the kickstand.
2. Using a spanner, loosen the rear wheel axle nuts on each side.
3. After the axle nuts are loosened, use a spanner to turn the
sprocket side tensioner bolt clockwise (to tighten) about one
turn, then repeat this process on the other side tensioner bolt.

4. Check the tension on chain and see if it has changed enough. If
not, repeat steps 3 & 4 until the proper tension is achieved.
5. Ensure that the chain tension is set the same on both sides of
the axle.
6. Tighten the axle nuts securely to 35-47 N.M.
NOTE: To loosen the chain tension, follow the steps above except
turn the tensioner bolts counter-clockwise (outward) to loosen the
chain.

LUBRICATING THE DRIVE CHAIN
The driving chain on your Revvi must be kept lubricated often to
avoid excessive wear. To lubricate the drive chain, follow the steps
below:
1. Park the bike on a level flat surface using the kickstand.
2. Lean the bike toward the kickstand so that the rear wheel
comes off the ground an inch or two.
3. As you rotate the rear tire, wipe down the chain with a clean
cloth to remove as much grime and build up as possible.
4. Spin the wheel and apply chain lube. You may need another
person to help you do this.
NOTE: The chain should be thoroughly lubricated but without
buildup of lube, which can collect dirt and grit which causes
damage to the chain.

REPLACING THE FUSE
The bike is equipped with a 30-amp fuse to protect system in the
event of electrical shorts. When a short or overload in the system
occurs, the fuse activates which will protect the wiring and help to
avoid possible fire.
Possible situations that can result in a blown fuse can be:
1. A worn or pinched wire in the system that causes a short.
2. Moisture in the system.
3. Overloaded electrical system.
In the event of a burned-out fuse, your Revvi will not work when
you turn it on and the indicator lights will not light up. To check and
replace the fuse, follow the steps on the following page:
1. Open the plastic battery case by removing both knob screws
(on the front and back of the battery case) and pulling the right
side panel off.
2. Locate the black rubber fuse housing, in the wiring above the
battery.
3. Open the rubber flip top lid and carefully pull out the fuse.
4. Inspect the fuse and replace if necessary.
5. Re-assemble the fuse holder and the body case, making sure it
is clean and dry inside and that all the wring is safely tucked
inside. Watch carefully for pinched wires.
NOTE: IF THE FUSE CONTINUES TO BURN OUT YOU HAVE
ENCOUNTERED AN ELECTRICAL PROBLEM. PLEASE CONTACT
SUPPLIER FOR SUPPORT.

ADJUSTING THE BRAKE
This bike is equipped with a rear disc brake system.
You should check the brake and make sure it is working properly
before each ride. The brake should feel firm when the lever is
pulled. You should not be able to pull the brake lever all the way
back to where it touches the hand grip. If you can squeeze the
brake lever all the way to the hand grip. Your brake needs
adjusting. There are two options to adjust the brakes:
OPTION 1: Adjust using the barrel roller.
1. Loosen the set ring on the barrel adjuster.
2. Screw the barrel adjuster out a few turns and then check the
tension in the lever.
3. If it feels right, re-tighten the set ring.
4. If not, repeat step 2 until the brake feels right and then tighten
the set ring nut.

OPTION 2: Adjust using the actuator arm on the brake caliper.
If you are not able to get enough adjustment using the barrel
adjuster, you may need to adjust the brake using the actuator arm
on the rear caliper.
1. Adjust the barrel adjuster on the brake lever all the way in, and
tighten the set ring.
2. Locate the rear brake actuator arm where the brake cable is
connected to the rear brake caliper.
3. Using an allen key, loosen the brake cable nut that secures the
cable to the actuator arm so that the cable can slide freely
through the bolt.
4. Slide the actuator arm forward until it stops, then back it off
about a half of an inch, making sure the cable slides freely
through the bolt.
5. Holding the actuator arm position, carefully re-tighten the
cable bolt until it is tight.
6. Check the brakes and make sure the work properly.
NOTE: Be sure the brake is not TOO TIGHT, which will impede
performance and cause excessive wear on the brake

CHECK THE TIRE PRESSURE
It is very important to check the tire pressure before every.
Running on low tire pressure can create a dangerous situation as
the bike will not handle properly and could cause the rider to lose
control. To check the tire pressure, locate the air valves inside the
rims on each wheel and remove the black plastic cap. Using a tire
gauge, check to make sure that there is a minimum of 15psi in each
tire, and no more than 30 psi of pressure in each tire.
REMOVING THE BATTERIES
The two batteries on your Revvi can be removed. To remove the
batteries, follow the steps outlined below:
1. Ensure the bike is switched off.
2. Open the plastic battery case by removing both knob screws
(on the front and back of the case) and pulling the right side
panel off.
3. Undo the metal bracket that holds the batteries in place. One
fixing on each side.
4. Unplug the plastic connector between the loom and the
batteries.
5. Once the batteries are disconnected carefully remove them
from the battery tray.
