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 Kepler, void your warranty and, in some cases, cause your Kepler
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. Ariel Rider shall not be responsible for any and all injuries or
damages resulting from the use of non-original components or spare parts.!

(
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. 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.
Electrical System"
The electrical system on your Kepler 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 Kepler’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 Kepler 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.
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. Do not use
motorcycle tires and/or different size tires on your wheels as the X-52 Ebike is not
designed for it.
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, and Grips
The suspension fork on your Kepler will affect the handling of the bike so you
MUST understand how it works before use. 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.
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.

!$
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:
• Kepler bike,
• Front wheel,
• Front fender,
• Warranty registration card (last page of this manual),
• Charger,
•Headlight,
• Assembly toolkit,

!%
• Pedals,
• Keys,
If there are any missing parts, please contact Ariel Rider E-bikes via our ticketing system
on the website.
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).
!

!&
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 into the pedal axle end, and a smooth exterior on the outside of the pedal axle.
Carefully thread the right pedal onto the crank on the right side of the bike (the side with
the drive train) slowly and by hand.
Dp not cross thread or damage the threads. Tighten securely using a pedal wrench to
avoid damage caused by wider wrenches."

Step 5:
Inflate tires to desired PSI. Recommended tire pressure is
indicated on the tire sidewall. Do not over-inflate or under-
inflate the tires.
