Using this manual:
This manual contains important details of the product, components and equipment, and information and
tips on operation and maintenance. This manual contains many warnings and cautions concerning safe op-
eration and consequences if proper setup, operation and maintenance are not performed. Carefully review
all information in this manual and immediately contact Euphree if you have any questions.
The note “WARNING” within this manual should be given special care. Users should also pay careful atten-
tion to information in this manual that begins with NOTICE.
Keep this manual along with any other documents that were included with your ebike for future reference.
All content in this manual is subject to change or withdrawal without notice. Assembly and rst adjustment
of your ebike from Euphree requires special tools and skills. It is recommended that assembly and rst ad-
justment be completed by a certied, reputable ebike mechanic unless you are mechanically inclined.
General information:
Euphree recommends having a certied, reputable ebike mechanic to assemble your ebike. If you are not
sure you have the experience, skills, and tools to correctly perform all assembly steps, consult a certied
reputable bicycle mechanic. Even if you have the experience, skill, and tools to complete assembly, Euphree
recommends that a certied, reputable ebike mechanic completes and/or checks your assembly before
your rst ride. We recommend that a certied, reputable ebike mechanic complete future adjustments,
maintenance or tuning. The cables, spokes and chain will stretch and bolted connections can loosen af-
ter an initial 50-100 miles (80-160 km) (depending on riding conditions such as total weight, terrain, riding
style). Regular inspections by a certied, reputable ebike mechanic are important for ensuring the safety of
your ebike.
Be sure to follow all laws for using an electric ebike in your region. These laws may limit where you can ride
your ebike and may specify mandatory equipment and use of hand signaling when riding.
Changing components or attaching accessories: The use of non-original components, spare parts, or acces-
sories can jeopardize your safety, the safety of your ebike and can void your warranty.
Replacing original components or installation for third-party accessories or accessories from Euphree not
explicitly recommended for your ebike model is at your own risk. Using aftermarket components or ac-
cessories may void your warranty. Using aftermarket components or accessories may create unsafe riding
conditions, damage to property or to your ebike, or result in serious injury and/or death.
Safety check before each ride: Inspect your ebike prior to every use. Failure to thoroughly inspect could re-
sult in serious injury or even death. If you are unsure of how to conduct a complete check of the condition
of your ebike before every ride, consult a certied, reputable ebike mechanic.
Electrical system:
In addition to a complete safety check, it is critical that you familiarize yourself with all aspects of your
ebike’s electrical system and check for proper operation before every ride. The front and rear brake levers
contain safety power cuto switches. When the brake levers are applied, the hub’s motor assistance is dis-
abled. Both levers should be checked for correct operation before every ride. The throttle should provide
smooth acceleration when gradually applied. If the throttle, brake lever cuto switches, pedal assistance or
lighting are functioning abnormally or not working, immediately discontinue use of your ebike and contact
Euphree for assistance. Before every ride, ensure the battery is adequately charged and operating properly.
Ensure that the battery charger is unplugged from the outlet and battery, and make sure to store the char-
ger in a safe location before riding. The battery MUST be locked onto the frame battery mount correctly
before use. Do not operate the electrical system if the battery is removed.

Accessories and hardware:
Before every ride, ensure all hardware is secured and approved accessories are properly attached per man-
ufacturer’s instructions. If you do discover something you are unsure about, have it checked by a certied,
reputable ebike mechanic.
Tires and wheels:
Your wheels should always spin straight and must be repaired or replaced if they wobble when spinning. If
you notice a side-to-side wobble or up-and-down wobble, or if your wheels become untrue or spokes loos-
en (which can happen with normal use), we recommend a certied, reputable ebike mechanic to perform all
wheel tuning operations. Do not attempt to true wheels or tighten spokes unless you have adequate knowl-
edge, tools and experience. Even if you have adequate knowledge, tools and experience, we recommend
that a certied, reputable ebike mechanic check your work. Before every ride, always ensure the tires and
inner tubes have the correct amount of air pressure and are in good working condition without any visual
damage.
Always replace tires and inner tubes with punctures, cuts or damage before you ride. Tires without the cor-
rect amount of air pressure can increase tire and component wear and make unsafe riding conditions.
Suspension, handlebar, grips and seat adjustments:
The suspension fork on your ebike will aect your ebike’s handling and should be properly adjusted for
your weight and terrain. Ensure the handlebar and handlebar stem are properly aligned, secured to rec-
ommended torque values and tted to the user. Loose, worn or damaged handlebar grips should be re-
placed before you ride. The seat and seatpost should be properly aligned and tted to the user with seat-
post quick release properly tightened, fully closed and safety secured before riding.
Any major or minor impact to your City Robin can compromise the integrity of the frame, electronics and
components. If your City Robin has experienced an impact, do not ride your ebike until it has been inspect-
ed by a certied, reputable ebike mechanic.
Hydraulic braking systems must be “bedded in” upon rst use. When fully squeezing the brake levers, en-
sure that neither the front nor the back brake lever touches the handlebar.
The City Robin has been designed with a maximum weight limit of 286 lbs (130 kg) for total payload (rider,
clothing, luggage, ebike accessories, cargo). Exceeding the weight limit will void all warranties and may re-
sult in unsafe operating conditions, damage to ebike or property, injury and/or death.
To reduce the risk of damage to your ebike and injury to yourself and/or others, keep children away from
the ebike and under close supervision when the product is in use near children.
Safeguard against corrosion and rust.
Your ebike has electric components. Damage to the electrical system caused in any manner, including
water damage, can lead to electrical system malfunction, failure of battery, or electrical re and consequent
injury, property damage or death.
Minimize the chance of water damage by following all recommendations.
Tore ebike in an upright position and under shelter.
• Do not leave the ebike in the rain.
• Do not leave the ebike exposed to corrosive substances.
Corrosive substances can include water, salt, or de-icing substances.
If your ebike is exposed to rain or other weather elements, dry your ebike immediately afterward and apply
anti-rust treatment to the chain.

WARNING: Ensure that all hardware is properly tightened, all components are secured, and perform all
safety checks before your rst ride. Failure to properly assemble your bike can cause damage to property,
serious injury and/or death. Check that all components including handlebar stem, seatpost or seat saddle
DO NOT extend beyond any minimum insertion marking etched in components.
WARNING: Both wheels must be properly secured before operating your bike. It is critical to check the
tightness of the rear wheel axle nuts, as mechanisms and components may become loose during shipment
or over time. Upon arrival and on a regular basis, you should inspect the torque and security of all wheel
mounting hardware.
WARNING: After assembly, before your rst ride, before all rides and after any time your ebike is left un-
supervised, always check to ensure that all latches, levers and quick releases are secured and undamaged.
Handlebar stem and/or seat post may become loose and can result in loss of control, damage to property,
serious injury and/or death.
Adjusting the seat height:
For most users, the seat height should be set by placing the ball of their foot on the pedal when the crank
is at its lowest point. In this orientation, the leg should be almost fully extended, with a slight bend at the
knee. Correct seat height should not allow leg strain from overextension and hips should not rock from side
to side when pedaling.
To adjust seat height:
1. Open the quick release lever by swinging the lever open and outward fully (pictured below).
2. Move the seat up and down by sliding the seatpost in or out of the seat tube to set to desired seat height.
3. After tightening the adjustment nut (located opposite of the quick release lever), close the quick release
lever fully so that the seat cannot move up, down or to the left or right.
WARNING: A loose seat clamp or seatpost adjustment bolt can cause damage to the ebike, loss of control,
serious injury and/or death. Regularly check to make sure that the seat clamp is tightened. Prior to rst use,
properly tighten the seat clamp via the seat adjustment bolt.
WARNING: DO NOT raise the seatpost beyond the minimum insertion marking etched into the seatpost
tube If the seatpost is raised beyond the minimum insertion point, the seatpost or frame may break, which
could cause a rider to lose control and fall, resulting in damage to the ebike, to property, or serious inju-
ry and/or death. Ensure the minimum insertion markings on the seatpost are inside the seat tube of the
frame.
Adjusting the seat position and angle is critical for rider comfort and posture. please use side adjustments
on the seat post to achieve the optimum angle. the seat should be horizontal or slightly downward.
Adjusting the suspension fork: the suspension fork can move up and down up to cushion bumps in the rid-
ing surface. if desired, the suspension fork can be locked out as a rigid fork which will generally yield higher
pedaling eciency.
• The right suspension fork has a actuator dial on it for adjusting the suspension rigidity
• A rigid suspension fork is not as comfortable as a compressible fork

Rider comfort:
• Depending on the rider’s preference, ability and experience with ebike riding, lowering the seat so the
rider can put one or both feet on the ground without dismounting from the seat may oer a safer and
more comfortable riding experience.
• For maximum comfort, the rider should not overextend arms’ reach when riding. ensure the handlebar
and brake lever angles allow for a comfortable arm position and relatively straight line from forearms,
wrists and hands. ensure handlebar angle allows the handlebar to remain clear of the rider’s body while
turning.
• A ebike tting professional should be consulted to ensure a proper t. if you have questions regarding
proper t, consult a certied, reputable ebike mechanic.

BRAKES:
WARNING: Do not touch the brake rotor. The brake rotor has sharp edges and can get hot while riding.
Touching the brake rotor can cause serious injury, slicing damage, or burns. Do not touch the brake rotor
with bare skin, as natural oils can transfer to the rotor, decreasing braking performance. Touch the brake
rotor only for necessary maintenance, only while wearing gloves or protective equipment, and only when
the brake rotor is cool and not moving.

WARNING: Never use the front brake by itself. First apply the rear brake, then second apply the front
brake. Use both brakes for all braking operations. Braking with only the front brake can cause loss of con-
trol, injury and/or death. Braking with only the front brake excessively stresses components and can cause
damage to the ebike and parts.
WARNING: Ensure brakes are working correctly and that all braking system components are free from
damage. Ensure that when you fully squeeze the brake levers that neither the front nor the rear brake le-
vers make any contact with the handlebar. Perform this check before every ride. If you nd a problem, take
your ebike to a certied, reputable mechanic to have the brakes repaired.
WARNING: Hydraulic brake uid can be an irritant when it contacts human tissue. If contact with skin
occurs, immediately wash o brake uid. If contact with eye(s) occurs, immediately ush eyes with fresh
water continuously for 15 minutes. Consult with medical personnel.
Operation section:
Do not attempt to operate your ebike until you have read and understood all sections of this manual. The
safety warnings throughout the manual must be followed to prevent accidents, damage to ebike and/or
property, injury and/or death. Damage caused by failing to read, understand and follow all instructions is
not covered under warranty. Contact Euphree if you have questions regarding assembly or operation.
Users must fully understand the ebike’s power systems before operating. Users must take extra care when
rst applying the throttle mechanism. Throttle allows for full power to be applied from a stop. Pedal assis-
tance should also be fully researched and understood before rst use. Failure to take care and familiarize
yourself, and failure to practice the operation of the power systems on your ebike can lead to damage,
serious injury and/or death.

Start-up procedure:
• After the e-bike has been properly assembled, all components are secured correctly and the user has
read this entire manual, user may turn on the e-bike and select a power level as outlined below:
• Test the battery lock security. Ensure the key port is locked indicating the battery is securely in place
inside the frame.
• Remove the key. Carefully use both hands to test that the battery is securely locked into place.
• Make sure that handlebars and seats are properly adjusted. Note that lowering the seat so that the
rider can put one or both feet at on the ground without dismounting from the seat may oer a safer
introduction to operating the e-bike.
• Ensure handlebar faceplate bolts and seatpost quick release are fully secured.
• Turn the e-bike on by holding the M on the mode selector on the left hand side of the handlebar.
WARNING: The key must be removed from the battery before mounting or operating the ebike. Leaving the
key inserted in the key barrel while mounting or dismounting, while removing an unlocked battery from the
frame, and/or while operating the ebike can cause damage to the key or battery, and can cause damage to
property, serious injury and/or death.
1. Turn on the headlight and taillight if needed by holding down the up arrow. A light indication will appear
on the screen indicating that the lights are now on.
2. Select the desired level of pedal assistance between level 0 through 5 using the up and down arrows on
the LCD display remote. Level 0 indicates pedal assistance is inactive. Level 1 corresponds to the lowest
level of pedal assistance. Level 5 corresponds to the highest level of pedal assistance. Start in PAS level 0
and adjust from there.
3. Begin riding carefully. With proper safety gear, prior experience in bicycle riding, and after reading this
manual in its entirety, the rider may now operate the Euphree ebike. On a at surface, most riders
should be able to begin pedaling the ebike with pedal assist level 0 or 1. You may also gently use the
throttle to accelerate or maintain desired speed.
4. The throttle is used by slowly, gently and carefully pressing down the thumb into the throttle lever. The
throttle is active when the ebike is turned on. Do not use the throttle unless you are riding the ebike.
WARNING: Never use the throttle while dismounted. While dismounted and moving the ebike, ensure that
the ebike is powered o to prevent application of the throttle.
Power system
How pedal assist works:
The user can engage the pedal assist system (PAS) while pedaling. Use of the PAS will recruit assistance
from the motor and will help propel the ebike forward. PAS uses a cadence sensor built into the drivetrain.
This cadence sensor detects when the user is pedaling and signals the electric motor to provide assistance.
The user selects ve levels of pedal assistance (PAS 0, 1, 2, 3, 4, 5). PAS 0 indicates no pedal assistance will
be provided.
How the throttle works:
The throttle is located on the right side of the handlebar. The user can engage the throttle by pushing down
with the thumb. To engage the throttle while riding, slowly push the throttle lever down with the thumb.
The more you push, the more powerfully the throttle will propel the ebike forward. Once you release the
throttle or apply the brakes, the throttle will no longer be engaged. Always keep on hand on the brake lever
and be prepared to squeeze the brake lever when using the throttle. You should not use your throttle if
local regulations prohibit the use of throttle on ebikes. It is the user’s responsibility to research, understand
and follow ebike regulations and all trac law.
WARNING: Even if you are an experienced ebike user, all users must read and implement the procedures
and information described in the owner’s manual and any manuals included with each subcomponent.
Headlight and brake light features turn on by holding the up arrow for 5 seconds.
