WELCOME
First off, welcome to the Wattwheels family! We’re so happy to have you on board! You have picked a great model and, in this manual, we’re going to
break down the basics to make sure that your bike remains in top shape and performs to the highest standard.
You’re about to experience the ride of your life. To get you out and having fun as quickly and as safely as possible please read entire the manual
carefully, paying close attention to the safety section.

TRIP/ODO & TIME
To toggle between the various modes short press the M key to switch between them.
BATTERY DISPLAY CAPCITY
The LCD readout on the handlebar of your Omnia features a battery capacity gauge (much like the fuel gauge on a car). It is recommended that users
stop operating the bike on electric once the indicator starts flashing on the last bar and recharge. Remember you can still ride without using the
motor or display.
PAS (Pedal Assist Modes)
Pedal assist modes (shown at the top of your display) start from 1 and goes up to 3. PAS level 1 is the first pedal assist level and will give you some
slight assistance. Press the up and down arrows on the control panel to toggle between the levels. As you select the higher levels, the assistance will
increase with level 3 basically doing all the work for you. Using higher levels of PAS will drain the battery faster. The recommended level is PAS 1-2 to
ensure good battery life. Note- PAS 0 means no assistance from the motor and you would have this on if you wanted to ride without assistance but
measure distance/speed etc.
If the bike is stationary for a period of 5 minutes or longer without any movement it will automatically turn off. These are safety features employed on the bike.
If transporting the bike on the back of a vehicle, please ensure the display is covered with a waterproof cover. Although they are designed to be ridden in wet
conditions traveling at high speeds in wet weather can cause water to get past the display seals.

BRAKES
The Omnia electric bikes are equipped Tektro hydraulic disc brakes. Please be aware the hydraulic disc brakes are very strong, so care is to be taken
braking while getting familiar with the bike. The front wheel brake is located on right hand side with the rear wheel brake on the left. For riders which
prefer the brakes the other way around please get your nearest bike shop to switch over if required.
TYRE PRESSURE
To avoid flats, keep tyre pressure at the recommended PSI. You will find the pressure range written on the side of the tyre. For good all round use we
recommend 60-70PSI
Gates Carbon Belt Drive
Your Omnia is equipped with a Gates CDX carbon belt drive system. Unlike a normal bike with a chain, The Gates carbon belt does not have any
moving parts and does not require any form of lubrication. It is important to get familiar with the instructions and care details of the Gates carbon
belt for proper use and maintenance.
Instructions can be found here: https://www.gatescarbondrive.com/resources/manuals-and-tech
Shimano Nexus Hub
The Omnia is fitted with a Shimano Nexus 3 speed hub gearing system. Unlike a regular derailleur system, the gears are on the inside of the rear hub
shell and does not require a derailleur. To change gear on a Shimano Nexus gearing system requires you to stop pedalling, use the grip shifter to
change gear then resume pedalling again. Failure to do this may cause the gears to “clunk” and wear prematurely.
More info can be found here: https://bike.shimano.com/en-EU/product/component/nexus-inter3/SG-3D55.html

DRIVING RANGE
The range of your Omnia is the distance the bike will travel on a single full charge of the battery pack. The range values in this manual are estimates
based on expected usage characteristics. Some of the factors which effect range include changes in elevation, speed, payload, and acceleration,
number of starts and stops and ambient air temperatures. Tyre pressure and terrain are also important variables to consider.
We suggest that you ride conservatively when you first get your Omnia Bike to get to know your bike and travel routes.
Once you become familiar with the range requirements of your travel routes, and the capabilities of your Omnia Bike you can then adjust your riding
characteristics if you so desire.
The following table provides general estimates and outlines various factors effecting range and their combined estimated effects on range. This table
is meant to help owners understand the factors that can increase or decrease range, but Wattwheels makes no claims to the range that individual
users might obtain.
RANGE EXTENDERS
Range extenders are available for purchase to extend the range of your Omnia. The range extenders are battery packs that look like drink bottles and
fit inside of a bottle cage on the seat tube and plug into the frame near the charging port. The range extenders will double the battery capacity of your
Omnia. The range extenders are easy to install and only require plugging in and can be taken with you and used as a battery bank if you wish.
With the battery gauge located on the bottom of the display please take note on new bikes the gauge can drop quite quickly initially. If this happens don’t be
alarmed as this is normal and is due to the BMS (battery management system) we use in the bikes, and it will take a few charges for the cells to balance out.
There will also be instances of voltage sag where the voltage drops when using a high level of PAS, biking up hills or under a heavy load which again is normal.
As mentioned, it is good to do a few smaller rides first to get familiar with the bike and the range you can get depending on what settings you have the bike on.
Pay close attention to the section in looking after your battery to prolong and maximise its life.

ADJUSTING THE SEAT HEIGHT
Loosen the seat clamp using a 5mm hex key to raise or lower the seat height to the required position.
Ensure the seat post and seat are properly adjusted before riding. Do not raise the seat post beyond the MINIMUM INSERTION marking etched onto the seat
post. If your seat post extends from the frame beyond these markings, the seat post or frame may break, which could cause you to lose control and fall. Prior
to first use, be sure to tighten the seat clamp properly. A loose seat clamp or seat post binding bolt can cause damage to the bicycle or can cause you to lose
control or fall. Periodically check to make sure these the seat clamp is properly tightened.
RIDER COMFORT
To obtain maximum comfort, the rider should not overextend his or her arms reach when riding. To obtain the most comfortable riding position and
offer the best possible pedalling efficiency, the seat height should be set correctly in relation to the rider’s leg length. The correct saddle height should
not allow leg strain from over extension, and the hips should not rock from side to side when pedalling. While sitting on the bicycle with one pedal at
its lowest point, place the ball of your foot on that pedal. The correct saddle height will allow the knee to be slightly bent in this position.

BATTERY & CHARGING
To charge the battery first open the rubber cap located on the seat tube above the motor and plug the charging pin into the port, then plug the
charger into the wall socket. It is important to always plug the charger into the bike first and then the wall socket.

WATTWHEELS LTD
12
The charge left in the battery should be 50%-75% for long storage times.
Cleaning the battery and battery housing should only be done while disconnected and powered off. Use a dry rag or if needed a lightly damp rag.
DO NOT spray with high-pressured water as it may cause damage or possible short-circuiting. Only charge the battery with the supplied charger as others may
not function properly, and this increases the possibility of fire or explosion.
Do not store the charger or battery in a wet/damp place or in direct sunlight.
Lithium-ion batteries can last longer if you recharge with 10-15% of the charge remaining to prevent damage to the cells. Keep both the battery and charger
out of the reach of children and if there appears to be an issue with the charger or battery, stop use immediately and contact either the manufacturer or
Wattwheels at [e-mail]
BEST PRACTISES FOR EXTENDING BATTERY LIFE
o Avoid sudden starts and stops.
o Use low levels of PAS
o Keep within the recommended weight limit

WATTWHEELS LTD

CHARGING
•Firstly, insert plug of the charger into charging socket on the bike/ battery.
•Second, Insert the charger into the socket of the home power supply. It shows the power has already been put through when the indicator lamp of
the charger is on.
•It is charging when the indicator light is red. When the light turns from red to green, it indicates that the battery is fully charged.
•After the green light is on, the charger is “fill slowly mode". It will not be harmful to the battery if left to charge for a longer period or overnight. We do
recommend not leaving for longer than 48hours if possible
DO NOT use the charger of other brands to charge. The charger may not be compatible with some brands

USEFUL TIPS
• This specified load of the Omnia is 130kg, please don't exceed this otherwise it will void the warranty
• While riding, if the level of charge shows only one bar flashing is recommended to ride without power, in PAS 0 and charge as soon as you can.
• Turn off the display while parking or storing the bike.
• Inspect the bolts on a regular basis, to ensure that they are tight, and all components are secure. Pay close attention to crank bolts, cranks, stems,
front, and rear wheel nuts.
This is especially important if you are riding in demanding conditions.
• Regularly check the brake pads. The provided pads should be replaced if they have:
-Been contaminated
-Have less than .8mm of material
-Cracks or deformation
• To replace the brake pads or perform other maintenance please take it to a qualified bicycle mechanic at your local bike shop.
• Properly inflate your tyres according to riding conditions. Under-inflated tyres are prone to get flats, especially if riding off-road.
• Please don't dismantle and repair parts by yourself. Please go to your local bike shop. This bike comes with a manufacturer’s warranty (document
included) so for warranty claims please contact Wattwheels and we will arrange a service agent close to you to look at the bike. We carry spare parts
so anything electrical that a standard bike shop doesn’t have we will ship to your nearest retailer

PARKING, STORAGE & TRANSPORT
Please follow these basic parking, storage, and transport tips to ensure your bike is well cared for on and off the road.
o When pushing the bike manually, turn off the power to avoid accidental acceleration from the motor.
o It is recommended to park indoors.
o Switch off the power to conserve battery. Remove the range extender battery (if installed) from the bike and take with you for security if needed.
o in public places, your Omnia Bike must be parked in accordance with local rules and regulations.
o If you must park outdoors in rain, or wet conditions you should only leave your Omnia Bike outside for a few hours and proceed to park the bike in
a dry location afterwards to allow all the systems to dry out. It is recommended to dry the bike off with a towel prior to storage. Never put your Omnia
away wet. Much like a regular bike, using in wet conditions mandates a more regular maintenance schedule to ensure your bike does not become
rusty, corroded and to ensure all systems are always working safely.
o Do not park, store, or transport your Omnia Bike on a rack that is not designed for the size and weight of the bike.
o Locking up your bike is recommended to ensure your bike is secure and the chance of theft is reduced. Wattwheels makes no claims or
recommendations on the proper lock, hardware, or procedures to secure your bike, but we do recommend you take the appropriate precautions to
keep your Bighorn bike safe from theft. Consult your local Wattwheels dealer for their lock recommendations.
