RIDING TIPS
•Maximum weight: 350 pounds (including rider.)
Age requirements: This e-bike is not intended for use by minors
or children. Any use of the e-bike in this manner should be done
under constant parental supervision after the e-bike's systems,
including the electric motor, acceleration, and braking, have been
clearly explained. Kasen Electric Bicycles accept no liability in
event of injury or death caused under such conditions.
•Abilities –Using this product requires basic riding abilities and
using motorized vehicles. Such skills can be learned with this
product, but care should be taken. It is recommended that any
user know how to ride a bicycle before riding a Kasen Electric
Bicycle.
oRiding a bike that has a long wheelbase and can carry cargo
will take getting used to. Practice maneuvering and braking
on a flat, hazard and traffic-free area with and without cargo
before going out into the world. Carrying heavy cargo
involves risks, foremost of which can be decreased braking
power and increased stopping distance.
•Medical limitations –Do not use if you have an existing medical
condition, injury, or other limitation which could affect your
balance or an ability to ride an e-bike. Do not participate activities
that can endanger your health and safety. Kasen Electric Bicycles
accept no liability in event of injury or death caused under such
conditions.
•Usage limitations - This e-bike should be usable almost anywhere
a regular bike can be. You and users should be aware of any local
rules and regulations regarding motorized transportation. If you

or the users have questions, check with local authorities and the
local rules and regulations before riding your Kasen Electric
Bicycle.
•Weather –Your e-bike is designed to be water-resistant to rain
and snow. It is not designed to be subjected to prolonged heavy
rainfall or subjected to the increased water pressure that occurs
when transporting an e-bike on a car or truck during rain or snow.
Please protect your display from rain when transporting by car or
truck.
•When riding on roads and streets, always follow all traffic laws for
bicycles, including speed limits, unless otherwise advised by local
authorities.
•Transporting e-bikes: It is important to check e-bike rack weight
restrictions prior to transporting using a traditional e-bike rack.
Weight limits on bike racks are often not compatible with the
heavier weight of electric bicycles. As a result, special electric e-
bike racks are often required for safe transport. Please follow all
instructions on your e-bike rack or other racks you choose for safe
transport.
•Safety Equipment and Gear: User should always wear a helmet
when riding an e-bike, including on city surfaces in traffic or
trails. In addition to a helmet, User should wear clothing
appropriate and, in preparation for, the weather. When riding in
urban settings, particularly at night, User should wear bright
and/or reflective clothing to increase visibility to drivers.

RIDING INSTRUCTIONS
•Check the e-bike before every use to make sure the e-bike and
components, including, but not limited to, that wheels are secure,
brakes work, and the frame is solid, to confirm they are in working
order.
•Check battery level before every use to confirm it is charged.
General Components and use:
•Handlebars:
oRight side: Rear Brake Lever and Gear Shifter.
oCenter: Full-Color Backlit Display.
oLeft side: Front Brake Lever, Thumb Throttle, Display
Controls & Bell.
•Acceleration: The e-bike can be accelerated via regular pedal
motion and via electric motor by using the throttle.
oWhen starting from a stop, pedal the bike first, then engage
the thumb throttle. Failure to do so may damage the motor.
oWhen riding the e-bike up steep grades for extended
periods of time, use the Pedal Assist (PAS) and avoid using
the Thumb Throttle. Failure to do so may damage electrical
components and the motor.
•Braking: It is recommended that the Rear Brake is the primary
brake used, with the Front Brake being a secondary and support
brake. Rider should not depress Front Brake Lever only or at high
speeds, as an accident and serious injury could occur. The brakes
on your electric e-bike include an automatic motor cut-off, which

means the motor power will be shut off when the brake levers are
depressed.
•Body Position: First, you should have an e-bike in the size that
correctly matches and is appropriate to your body size (primarily
by height). The ideal body positioning is:
oSaddle at a height where you can fully reach the pedals but
not where your legs are cramped.
oWhen leaning forward, you can reach and control the
handlebars, including steering the e-bike.
▪When climbing, you may have to lean forward and
stand up on the pedals.
▪When descending, you may have to shift your body
weight backwards.
▪You need to make sure all these maneuvers are
possible so you can safely maintain control of the e-
bike.
•Speed and Abilities: As you ride more you may become more
comfortable with the e-bike at higher speeds and over challenging
terrain. Please ride within your limits. You agree not to hold
Kasen Electric Bicycles liable for any injuries incurred due to riding
above and beyond your limits and terrain abilities and speed.

SAFE STARTING & STOPPING
Remember that if pedal assist is turned on, the motor will turn on and
begin to push you forward anytime the pedals rotate (even if you rotate
the pedals unintentionally.) This could be unsafe if you weren't expecting
the motor to turn on.
To prevent accidentally engaging the motor on your e-bike, you
should turn off pedal assist (by setting the display to level zero) when
you are not using it.
The motor interrupt brake levers on Kasen e-bikes stop the motor from
running when they are squeezed. This adds an additional measure of
safety - when you are sitting on the bike but not moving (for example,
when stopped at a stoplight), get into the habit of squeezing the brake
levers. This habit stops you from accidentally engaging the motor.
Release the brake levers when you begin riding and intend to use pedal
assist again.
The motor interrupt brake levers can also control your speed in areas
where pedal assist is not desired. For example, if you are riding at slow
speed through a pedestrian mall, you can pedal to propel the bike
forward while simultaneously lightly dragging the brakes. This allows you
to ride without the motor turning on at all.
To prevent accidentally engaging the motor when you're done riding
your bike, power it off. Never leave your e-bike powered on when
parking, hanging from a hook in the garage, or while loading your e-bike
onto a car or truck rack for transport.
If your e-bike ever needs repairs or maintenance (for example, fixing a
flat tire), always completely power down the e-bike before starting work.

BATTERY AND CHARGING
The eTrike uses a Lithium-Ion battery, which can be charged either on or
off the bike. We recommend charging the battery indoors, in moderate
temperature conditions. To charge the battery, plug the charger into the
charging port and then connect it to a wall outlet. The LED indicator light
will be red when charging and will turn green when charging is complete.
When finished, unplug the charger from the wall outlet.
Taking proper care of the battery will ensure a long service life:
• Charge and store the battery indoors whenever possible. The
battery can be removed from the bicycle for this purpose.
• Avoid extreme hot and cold temperatures.
• DO NOT submerge your bike or any of the components in water.
This action will void the warranty.
To optimize the battery's performance over time, do your best to use
it (discharging and charging) at least monthly. If you won't be riding
your eTrike for an extended period, it's best to store the battery fully
charged. The lifespan of the battery is about 1000 charge/discharge cycles.
Battery capacity will reduce range and runtime over time.
Replacement batteries are available from Kasen to extend the life of
your e-bike.
When you install the battery on the eTrike, lock it into place with the
supplied key. To remove the battery, pull the lever located under the
saddle upwards and flip the saddle forwards. Turn the key on the left side
of the battery to the unlock position. Pull the handle, then gently lift the
battery out of its mount. Do not ride the bicycle if the battery rattles or
moves - it should be firmly attached.

ADJUSTING THE SUSPENSION FORK
The eTrike features a mechanical suspension fork to help you ride with
more comfort and control. You can use this adjustment to customize your
riding experience.
LOCKOUT
The lockout knob is located on top of the right (from the rider's
perspective) side of the fork crown. Engaging the lockout stops the fork
from moving at all. This is useful on smooth roads or extended uphill
pavement when no suspension is needed. If you find the fork movement
undesirable for the conditions, turn the knob counter-clockwise to engage
the lockout. Turn the knob clockwise to disengage the lockout when done.
Avoid riding the bike on rough terrain with the lockout engaged.

MAINTENANCE AND SERVICE
Properly maintaining your eTrike ensures its longevity and smooth
operation. Before assembling your bike, please watch the "How To
Assemble" video we've prepared for you. If you have questions during
the assembly process, please contact Kasen at [phone] or email
KasenBikeCustomerS[email protected]
Once you're up and running, please make sure:
• When cleaning your e-bike, use a damp cloth and gentle dish soap.
Note: DO NOT use a pressure washer or sprayer .
•Periodically apply a light bicycle lubricant to moving parts,
including the chain, derailleur pivots, and shifter cable inner wire
where it enters the cable housing.
•If you ride in wet or humid environments, clean and dry electric
connections and apply an anti-corrosive substance.
All bicycles will need a periodic tune-up or adjustments by a professional.
An annual "check-up" is beneficial. Your bike's service schedule will
depend on the frequency of its use. In between expert services at a bike
shop, we suggest:
•Keep tires inflated to their recommended pressure found on the
sidewall and check weekly.
•Clean the drivetrain and lubricate the chain (monthly)
For more information about further recommended maintenance, we
suggest the excellent video series offered by Park Tool on YouTube.

SAFETY
You should wear an approved bicycle helmet every time you ride a
bicycle, regardless of the legal requirement to do so. Additionally, some
jurisdictions require helmet use when riding Class II e-bikes like the
eTrike. You should comply with local law when riding your Kasen bicycle.
Your eTrike comes with reflectors and an LED reflective taillight; we
encourage you not to remove them. You should use the front and rear
lights when riding in dim or dark conditions.
Some jurisdictions restrict where e-bikes can and cannot be ridden.
These limits may include specific speeds and motor wattages. Your eTrike
is a Class II e-bike, 500 watts with pedal assist up to 21 MPH and throttle
up to 21 MPH. You should only ride it where it's legal and safe.
Your eTrike will run without the throttle plugged in. You can remove the
throttle to comply with local regulations if needed.

TROUBLESHOOTING
Having trouble with your eTrike? Most problems are easy to correct.
1. Start by making sure you have a charged battery. You may wish to
leave the battery on the charger overnight to ensure a 100%
charge before troubleshooting.
2. If your bike's motor will not engage or only engages intermittently,
double-check the cable connection where the rear wheel motor
plugs into the rest of the system. To function correctly, this
connector must be firmly and fully plugged in. If necessary, loosen
the clips holding the cable to the frame to create additional slack
in the cable, then re-tighten the clips after the motor cable is firmly
plugged in.
3. If you bent the derailleur hanger on your eTrike in a fall, don't
worry. It's actually designed to fail, sparing damage to the more
expensive frame, and is inexpensive to replace for this reason. If
you need more, they are available on Kasen.com or at partner bike
shops.
4. If your bike powers up normally and shows no error messages but
will not run when you turn the pedal assist on, check to ensure the
cadence (PAS) sensor under the crank arm is plugged in.

BATTERY TROUBLESHOOTING
Your e-bike battery uses several sophisticated monitoring systems to
prevent damage from overcharging, overheating, deep battery discharge,
charging with the wrong voltage, and other errors.
Please use the specific charger supplied with your bike. Other chargers
may not supply the correct voltage required for charging. Even if another
charger has the required voltage, it may not be programmed to initiate the
charge cycle. To resolve this:
1. Remove the battery from the bike.
2. Plug the charging tip into the battery.
3. Plug the charger into wall power.
4. Tap the power button on the battery once to turn it on.
5. Charge the battery overnight.
6. When charging is complete, put the battery back on the bike and
check for proper operation.
If a situation occurs that could damage the battery, the battery can go
into a protective "sleep mode" - the battery cells inside are OK, but the
battery won't turn on and won't take a charge. To "wake up" the battery,
please follow this procedure:
1. Put the battery on the bike.
2. Plug the charging tip into the battery.
3. Plug the charger into wall power.
4. Tap the power button on the battery once to turn it on.
5. Press and hold on the controls to turn on the display.
6. Allow the battery to charge overnight.

7. Once charged, remove from wall power and check for proper
operation.
Under specific circumstances, you might see one single LED flashing
constantly on the battery. One blinking LED is a warning of excessive
strain on the battery for its charge level. To correct this issue:
•Reduce the strain on the battery and charge the battery. If it will
not take a charge, please take the previous steps to resolve the
issue.
