CALIFORNIA PROPOSITION 65
WARNING: Operating, servicing, or maintaining a passenger vehicle or off-highway motor
vehicle can expose you to chemicals including engine exhaust, carbon monoxide, phthalates,
and lead, which are known to the State of California to cause cancer and birth defects or
other reproductive harm. To minimize exposure, avoid breathing exhaust, do not idle the
engine except as necessary, service your vehicle in a well-ventilated area and wear gloves or
wash your hands frequently when servicing your vehicle. For more information go to
www.P65Warnings.ca.gov/passenger-vehicle.

LET’S GET READY TO RIDE
Okay you are super tempted to ride the bike, but
let’s get the bike fully charged and ready to ride
before you go ride off into the sunset. Your bike
should come nominally charged when shipped. If
you ride the bike uncharged you could cause
problems with operating the bike. So let’s get
started!
PRE-RIDE SAFETY CHECK
Before every ride, it is the owner responsibility to check
and maintain your vehicle according to the schedule
below unless service is needed otherwise:
Check the Headlight, Tail Light, & Any Other Installed
Lighting for Proper Operation
Check Tire Rotation – Should Spin Smooth & Straight
Check Tire Pressure (32 psi F&R)
Check Front & Rear Brake Operation
Check Battery Charge Level
Check & Torque Fork, Axle, Handlebar, and Suspension
Nuts and bolts (see General Information > CTY2
Torque Specifications, page 27)
Whether you are a seasoned cyclist or new to the
electric motorbike scene, riding an ONYX CTY2 is
an awesome experience every time and
everywhere you get to ride one. Pedaling your heart
out is great exercise and gets the blood flowing for
sure, but being able to twist the throttle to give you
power whenever you need it gives you a rush and
a thrill like nothing else! However, there are some
general riding considerations to understand and
keep in mind your CTY2 that will keep you and
others around you safe and happy.

PREPARING FOR THE FIRST RIDE
Wear properly fitting protective gear including at minimum:
full-face helmet, gloves, long pants, long sleeve bright
colored shirt, full-toed shoes, and a reflective vest. Do not
wear loose fitting pants or shoes that can get caught in the
chain, pedals, or wheels. Additional items that can make
your riding experience safer, better, and more comfortable
can include sunglasses (that will fit and work with your
helmet) and a jacket. Be careful wearing anything that can
limit your flexibility, mobility, or vision.
If your locale does not require you to obtain and maintain a
valid motorcycle/moped driver’s license, ONYX strongly
recommends that you do so anyway. In addition to learning
more about and being tested on knowing the rules of the
road for safety reasons, having a moped/motorcycle
driver/rider license will help put any law enforcement agent
at ease in case they question your ride or ability to ride…
Additionally, even if your locale does not require you to
complete any formal training, ONYX strongly recommends
that you take a moped or motorcycle riding course for
proper training, especially if you are new to motorbikes in
general. Contact your State or local Department of Motor
Vehicles or law enforcement agency for any
recommendations or suggestions on training programs or
courses. These courses will often count as partial or full
credit for obtaining your motorcycle/moped driver’s license!
Be sure to attend to the following before your first ride:
Be sure to switch on headlight at low visibility. When
your bike is on there will always be a running light
halo on.
Obey all traffic regulations.
Use hand signals when turning or changing lanes.
Please respect property of others and ride carefully.
Keep your feet on the pedals at all times. Keep the
pedals level, especially on turns.
After reaching maximum speed, reduce the throttle
opening to 3/4. While the reduction in speed will hardly
be noticeable, energy consumption nonetheless will be
considerably reduced.
Remember that regenerative (regen) braking is very
strong and can sometimes slow the bike to a stop alone
but it can be unreliable especially at a full battery
charge. So always use the regen brake feature with
caution.

10 BASIC BATTERY + CHARGING GUIDE
Getting the maximum performance out of the Onyx CTY2 requires taking great care of its battery.
For detailed battery and charging information see OPERATING INSTRUCTIONS, BATTERY OPERATION, page 44.
CHARGING THE BATTERY
Your Onyx CTY2 will include a 5 amp charger
and a 23ah 60v battery.
1. Remove the seal cover from the charging
port located at the bottom right of the
battery carriage
2. Align the plug to the charging port. Note:
Charging port will only go in one way.
3. Once charging plug has been inserted, turn
the connector counter clockwise.
4. To ensure proper charging, the yellow tab
must fall into place. You will hear a click
once it’s in place. CONSTANT VOLTAGE CHARGING
When the Standard 5 Amp Onyx CTY2
charger light turns green that means 97%
(69.2 volts) of the charge is complete. The
remaining 3% to charge to 100% (71.4 volts)
takes 95 more minutes after the charger light
turns green. This last 3% is called “constant
voltage” and is done through trickle charging.
It is okay to charge the Onyx CTY2 to
97% (69.2 volts) (charger light turns
green) and go for a ride. Charging to
100% is not necessary every time.

PRO
TIP
+ Riding faster consumes more battery.
+ Become familiar with how many miles away your destination is going to be.
+ Keep your battery charge levels above 20 percent which is 57 volts on the display voltmeter.
+ How well the battery is taken care of directly impacts the CTY2’s performance, battery sag and top speed.
BATTERY SAG
Become familiar with the amount of battery sag full throttle
causes in eco mode, normal mode, and sport mode. Sag
is described as the amount of electricity drawn depending
on how much throttle is given. On a colder day it is not
uncommon at full throttle for the voltage sag to be 7 volts
and on warmer days for it to be between 4 volts to 5 volts.
Each mode limits the amount of sag.
Eco mode will help prevent cut offs by reducing battery
sag.
The amount of throttle given directly controls the
amount of battery sag.
BATTERY CUT OFF
When the amount of battery sag falls below 51
volts with a 23ah battery, the Onyx CTY2 will turn
off.
Cut off occurs because the battery management
is protecting the batteries from damage. If it
completely cuts out your battery will reset within 10
seconds. You will need your key fob to unlock the
bike.
One way to prevent the Onyx CTY2 with 23ah
battery from completely cutting off is to immediately
activate regenerative braking by using your rear
brake.

Research and understand your local laws and
classifications where you live as well as where
you intend to ride!
ONYX Motorbikes recommends that you register
and insure your CTY2 in one way or another if
you want to and IF YOU NEED TO. Please consult
your local laws.
Respect the environment, and tread lightly. Don’t
tear up or ride off of designated roads and trails. It
is cool to blaze your own trail sometimes, but
make sure it is OK to do so without damaging the
local vegetation or animal population!
Be aware of your surroundings. Remember that
e-bikes are quiet. Be aware of joggers, people
pushing strollers, and other cyclists that may be on
or near the paths and lanes that you may be using.
BEFORE YOU RIDE...

GENERAL SAFETY INFORMATION
The high performance CTY2 should be treated with
extreme caution. Proper safety gear, including a
regionally approved helmet, eye protection, riding
boots, gloves, and protective clothing should be
worn while riding to reduce the risk of potential
injury.
Never permit a guest to ride your electric motorbike
without proper instruction. Never use alcohol or
mind-altering drugs before operating your CTY2.
The owner assumes all responsibility while
operating their CTY2. The seller assumes no
liability for misuse or operator negligence.
Prior to each use the rider must check everything
in the “Pre-Ride Safety Check” section of the
Quick Start Guide.
Modifications and additional loads may affect your
bikes performance, handling, range and operation.
Use caution.
SAFETY INFORMATION
OPERATING SAFETY
INFORMATION

balancing of each and all battery cells as a system to maintain battery life and performance)
ONYX Battery BMS Management Scheme The BMS has an overcharge voltage protection function that detects and protects single cells in ad-
dition to serial groupings that will cut off charging to 4.25 V +/- 50 mV (recover at 4.15 V +/- 50 mV).
The over-discharge cutoff is 2.8 V +/-80 mV (recover at 2.85 V +/- 150 mV). Also each cell incorpo-
rates PTC and CID protections. PTC (Positive Thermal Coefficient) provides external short condition
cell protection, and CID (Current Interrupt Device) provides overcharge condition cell protection.
