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.
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.
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.
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. Ariel Rider shall not be responsible for
any and all injuries or damages resulting from the use of non-original components or spare parts.

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.
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.
Make sure to check your motor cable is not hanging, loose, and/or rubbing any of the moving parts. Failure to
do so may end up damaging the motor cable, which is not repairable, and will result in needing to replace the
motor itself, which is not covered under warranty.
See the PRE-RIDE SAFETY CHECKLIST for more information.

8
ELECTRICAL SYSTEM
The electrical system on your X-Class 52V 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 52V’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 52V immediately and contact the
Ariel Rider E-bikes Technical Support team for assistance.
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 nor 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.

9
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 damaged tires and inner tubes 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.
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.

10
SUSPENSION, HANDLEBAR, AND GRIPS
The suspension fork on your X-Class 52V will affect the handling of the bike so you MUST understand how it
works before use. Check to ensure the front wheel, handlebar, and handlebar stem are properly fastened,
aligned, and fitted to the user. Ensure all hardware securing the handlebar and seat are properly tightened.
Loose, worn, or damaged handlebar grips should be replaced before you ride.
BATTERY CHARGED, SECURED, AND UNPLUGGED
Ensure the battery is fully charged and is 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
securely before use. Ensure the battery charger is unplugged from the battery, the power 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. It is normal and expected
for the parts to be loose out of the box, we highly recommend checking all of nuts and the bolts
even if they’re already assembled on the bike itself upon delivery.
Check out the assembly video at https://youtu.be/5nbB0XxGYU0
STEP 1: Unpack the 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 52V bike
•Front wheel
•Front fender
•Charger
•Warranty registration card"
(last page of manual),
•Headlight
•Assembly toolkit,
•Pedals
•Keys
If there are any missing parts, please contact Ariel Rider E-bikes via our ticketing system on our
website.

STEP 2: Install handlebar onto stem.
•Remove the faceplate from the stem.
•Make sure that the control cables from the handlebar are
not twisted or wrapped around the fork when you mount
them to the stem.
•When affixing the faceplate, tighten the faceplate bolts
incrementally and evenly in an “X” pattern. When fully
clamped down, the gap between the faceplate and the
stem should be even from left to right, and from top to
bottom.
•Before final tightening, adjust the angle of the handlebars
so that the grips are close to being level with the floor, and
the brake levers are tilted downward at a 30-40° angle.
•Once tightened down, check that the handlebars are
secure and won’t move when you push on them.
STEP 3: Install the front wheel components.
•When properly installed, the front wheel should be fully seated in the dropouts of the front fork, with the
washers and axle nuts on the outside of the fork. Tighten axle nuts to 40 N m.
•Ensure that the front wheel is well secured before moving on to the next step. !

14
STEP 4: Install the pedals.
It is very important to install the pedals onto the correct sides of the bike. The pedals are
not identical. The threads on each are different, and they will damage the crank arms if they
are installed on the wrong sides.
•With both pedals in hand, look carefully at the threaded part of each pedal. When comparing this
area of the two pedals, one will have ridges and will be marked with an “L” on the end. The other
one will be smooth and marked with an “R” on the end.
•This corresponds to the side of the bike they go on. The left side of the bike is the same side that has
the brake calipers. The right side is the side that has the chain. It is the same as your left and right side
when sitting on the bike.
•The left pedal is reverse threaded and tightens counterclockwise. Carefully thread the pedal into
the left crank arm 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 normally and tightens by turning clockwise. Carefully thread the pedal
into the right crank arm by hand, slowly. Do not cross thread or damage the threads. Tighten
securely with a pedal wrench.

15
STEP 5: Inflate tires to recommended PSI indicated on the tire sidewall (30 psi).
•Do not over-inflate or under-inflate the tires. This is important with fat tire bikes as underinflated tires will
want to pull the handlebars to one side or the other while riding.
STEP 6: Always check that the battery is locked to the frame of the X-Class 52V before riding.
STEP 7: Install the headlight and front fender in place.
•Make sure the bike is not turned on while installing the headlight as this may damage the
controller.
•While plugging the headlight cable in, align the arrows first & push the connectors together without
twisting.
•The headlight should be aimed at a slight downward angle. This is to keep from blinding other drivers
and riders at night.
STEP 8: Final checks:
•Double check all fasteners are tightened to correct torque values.
•Verify that the brake levers feel firm when brakes are applied and that they do not pull back to the
handlebar grips when applied.
•If the levers can be pulled all the way back to the grips, DO NOT RIDE THE BIKE, seek out a
qualified bike mechanic, or contact Ariel Rider product support .
•Check that all the cables are secured and that nothing is going to rub on the chain or the tires.

16
STEP 9: 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.
NOTICE: If you have any questions regarding the assembly of your bike, contact Ariel Rider E-
bikes. If you are not able to ensure all the assembly steps in the assembly video are performed
properly, or you are unable to view the assembly video, please consult a certified, reputable local
bike mechanic for assistance in addition to contacting Ariel Rider E-bikes for help.
NOTICE: Ensure all hardware is tightened properly following Recommended Torque Values and all
safety checks in this manual are performed before the first use of the bike. Do not extend the stem
beyond the maximum angle markings on the stem which is etched into the side of the stem. Ensure
that all hardware is properly tightened (to the recommended torque values included in this manual)
and components are secured before moving on to next step otherwise damage to the bike,
property, serious injury, or death could occur. Ariel Rider shall not be responsible for any and all
injuries or damages resulting from hardware not being tightened correctly or components that are
not properly assembled.

Before using the bike, always check to ensure all latches, and levers, are properly secured and
undamaged. Check that they are correctly secured before every ride and after every time the bike is
left unsupervised, even for a short time. Otherwise, the handlebar stem and/or or another
component may come loose and can result in loss of control, damage to the bike, property, serious
injury, and/or death. Ariel Rider shall not be responsible for any and all damages resulting from any
