General Info
Assembly and Fit
Correct assembly and fit are essential elements of ensuring your bicycling safety,
performance, and comfort. Even if you have the experience, skill, and tools to complete
these essential steps before your first ride, Ariel Rider E-bikes recommends having a
certified, reputable bike mechanic check your work.
NOTICE: If you do not have the experience, skill, and tools to complete assembly and fit,
Ariel Rider E-bikes highly recommends having a certified, reputable bike mechanic
complete these procedures as well as any future adjustments or tuning.
NOTICE: A critical aspect of assembling your bike from Ariel Rider E-bikes is securing the
front wheel and checking the tightness of the rear wheel axle nuts. Both wheels need to
be properly secured before operating your bike, and these nuts are to be checked every
45-50 miles.

Mandatory Equipment and Use Locations
Before all rides, ensure you have all required and recommended safety equipment and are
following all laws pertaining to using an electric bike in your region. For example, these
laws may specify the need for mandatory equipment, use of hand signals, and where you
can ride.
Changing Components or Attaching Accessories
The use of non-original components or spare parts can jeopardize the safety of your X-
Class, void your warranty and, in some cases, cause your X-Class to not conform with
laws pertaining to your bike.
The replacement of original components or installation of third-party accessories
or accessories from Ariel Rider E-bikes not explicitly recommended for your bike
model, is at your own risk. Using aftermarket accessories or components that
have not been tested by Ariel Rider E-bikes for safety and compatibility may void
your warranty, create an unsafe riding condition, damage your bike by Ariel Rider
E-bikes, or result in serious injury and/or death.

6
Safety Check Before Each Ride
Always check the condition of your bike before you ride in addition to having regular
maintenance performed. If you are unsure of how to conduct a complete check of the
condition of your bike before every ride, you should consult a certified, reputable bike
mechanic for assistance. See the Pre-Ride Safety Checklist for more information.
Electrical System
The electrical system on your X-Class offers various levels of power assistance and
lighting for different operating conditions and user preferences. It is critical that you
familiarize yourself with all aspects of your X-Class’s electrical system and check to see
that it is working correctly before every ride. The front and rear brake levers contain
safety power cutoff switches, which disable the hub motor’s assistance when applied,
and both levers should be checked for correct operation. The throttle should provide
smooth acceleration when gradually applied. If the throttle, brake lever cutoff switches,
pedal assistance, or lighting is not functioning normally, intermittent, or not working,
please discontinue using your X-Class immediately and contact the Ariel Rider E-bikes
Technical Support team for assistance.

7
Brakes
Ensure brakes are working correctly, all braking system components are free from
damage, and properly secured. When you fully squeeze the brake levers, ensure neither
the front or rear brake levers touch the handlebar. Take your bike to a certified,
reputable bike mechanic to have the brakes repaired if you find a problem.
Tires and Wheels
Your wheels should always spin straight and must be repaired or replaced if they
wobble side to side or up and down when spinning. If your wheels become untrue or
spokes loosen, do not attempt to true or tighten unless you have adequate knowledge,
tools and experience. It is recommended that a certified, reputable bike mechanic
performs all wheel tuning and truing operations on your bike from Ariel Rider E-bikes.
Ensure your tires and inner tubes are in good working condition without any visual
damage and have the correct amount of air pressure. Always replace tires and inner
tubes with punctures, cuts or damage before you ride. Tires without the correct amount
of air pressure can reduce performance, increase tire and component wear, and make
riding your bike unsafe.

8
Accessories, Straps, and Hardware
Ensure all hardware is secured and all approved accessories are properly attached per
the specific component manufacturer’s instructions. It is good practice to look over all
hardware, straps, and accessories before each ride and if you do discover something is
wrong or find something you are not sure about, please have it checked by a certified,
reputable bike mechanic.
Suspension, Handlebar, Grips, and Seat Adjustments
The suspension fork on your X-Class will affect the handling of the bike so you MUST
understand how it works before use. The suspension fork should be properly adjusted
for your weight and terrain. Check to ensure the handlebar, handlebar stem, and seat
post are properly fastened, aligned, and fitted to the user. Ensure all hardware securing
the handlebar and seat are properly tightened including all quick release levers. Loose,
worn, or damaged handlebar grips should be replaced before you ride.
Battery Charged, Secured, and Unplugged
Ensure the battery is fully charged and operating properly. The battery gauge on the LCD
Display and battery mounted charge status indicator should read similarly. The battery
MUST be locked onto the frame battery mount properly before use. Ensure the battery
charger is unplugged from the battery, outlet, and stored in a safe location before you ride.

Assembly Instructions
NOTICE: The following assembly steps are only a general guide to assist in the assembly of your
bike from Ariel Rider E-bikes and is not a complete or comprehensive manual of all aspects of
assembly, maintenance, and repair. We recommend you consult a certified, reputable bike
mechanic to assist in the assembly, repair, and maintenance of your bike.
Step 1: Unpack bike from the carton and carefully set out all contents of the box.
Remove packaging material protecting the bike frame and components. Please recycle
packaging materials especially cardboard and foam (all #6 EPS foam). Ensure you have
received the correct frame size before assembling the bike and that all pieces are
included in the package including:
•X-Class bike,
•Front wheel,
•Front Fender,
•Warranty Registration Card,
•Charger,
•Headlight,
•Assembly toolkit,

11
•Pedals,
•Keys
If there are any missing parts, please contact Ariel Rider E-bikes.
Step 2: Install handlebar onto stem. Be sure to center the handlebar and ensure hardware
is properly secured. Before fully securing the handlebar to the stem, adjust the stem angle
using the Allen bolts on the side of the stem. Install the handlebar so the grips are
approximately parallel to the ground, and secure them to the recommended torque value
(22-29 Nm).

12
Step 3: Install the front wheel components. Ensure front
wheel is properly secured before moving on to the next
step. When properly installed, the front wheel should be
fully seated in the dropouts of the front fork, and the
washers and nuts should be on the outside of the fork,
please make sure everything is fully and properly secured.
Step 4: Install the pedals. Locate the pedal marked with
an “L” at the pedal axle end and notches on the outside of
the pedal axle (1, at right). The pedal marked “L” with
notches goes on the crank on the left side of the bike
(which is the same as a rider’s left side when riding). The
left pedal is reverse threaded and tightens
counterclockwise. Carefully thread the pedals by hand
slowly. Do not cross thread or damage the threads.
Tighten securely using a pedal wrench to avoid damage
caused by wider wrenches, as shown in assembly video.
The right pedal is threaded so that it is tightened by turning clockwise, has an “R”
stamped

13
into the pedal axle end, and a smooth exterior on the
outside of the pedal axle (2, above). Carefully thread the
right pedal onto the crank on the right side of the bike
(the side with the drivetrain gears) slowly and by hand.
Do not cross thread or damage the threads. Tighten
securely using a pedal wrench to avoid damage caused
by wider wrenches.

14
Step 5: Inflate tires to desired PSI. Recommended tire
pressure is indicated on the tire sidewall. Do not
overinflate or underinflate tires.
Step 6: Always check that the battery is locked to the
frame of the X-Class before riding. The Start-Up Procedure
section of this manual has more information on the key
positions of the battery; on and locked to the frame, off
and locked to the frame, and off and unlocked (ready for
removal from the frame).
Step 7: Review the remainder of the manual. Once the bike has been assembled per the
above instructions and the assembly video available from website read, understand, and
follow the procedures outlined in the remainder of the manual before operating the bike.
