For better pedaling, safety and overall riding comfo, positioning the seat at the right height is
impoant. The rider's leg length is used to determine the seat's position. When you pedal, your hips
should remain level and your legs should be almost fully extended at the bottom ofthe pedal stroke, but
not over-extended.
To determine the right seat height, sit on the eBike with one pedal at its lowest point andplace the ball
of your foot on the pedal. Your leg should be almost fully extended(not lockedout) with a slight bend
at the knee.
Adujst the seat and the head of the seat
is parallel with the top tube.

The suspension fork can move up and down up
to 80mm to cushion bumps in the riding suace,
which can make riding on a rough road or trail
smoother and more comfoable.Depending on
a rider’s preference, the suspension fork can be
locked out as a rigid fork, which will typically
yield higher eciency while pedaling.
The lockout lever (1) , located on top of
the right side of the suspension fork, can be
turned counterclockwise until it stops to
completely lock out the suspension fork’s travel.
To unlock the lockout lever, turn the knob clock-
wise until it stops. When the lockout lever is
unlocked, resistance can be adjusted by turning.
The preload adjustment knob (2), located on the top of the left side of the suspensionfork.
To soften the ride, subtract resistance by turning the preload adjustment knob counterclockwise, in
the direction of the small “-” on the knob. To make the suspension stier when going over bumps,
add resistance by turning the preload adjustment knob clockwise, in the direction of the small “+”
on the knob.

NOTICE: Ensure the seatpost and seat are properly adjusted before riding. DO NOT raise the
seatpost beyond the minimum inseion marking etched into the seatpost tube (as shown at
right). If the seatpost projects from the frame beyond these markings (shown far right), the
seatpost or frame may break, which could cause a rider to lose control and fall. Ensure the
minimum inseion markings on the seatpost are inside the seat tube of the frame.
Before using the bike, always check to ensure all latches, levers, and quick releases are properly
secured and undamaged. Check that they are correctly secured before eve ride and after
eve time the bike is left unsupeised, even for a sho time. Otherwise, the handlebar stem
and/or seatpost may come loose and can result in loss of control, damage to the bike, propey,
serious inju, and/or death.

Turn on/o the headlight and taillight. Press the switch to ON/OFF. Note: the headlight will light up
automatically when the light is dim when the display is on even if the switch is OFF.
Select the desired level of pedal assistance (PAS) between levels 0~5 using the + and - on the LCD
display. Level 1 corresponds to the lowest level of pedal assistance, and level 5 corresponds to the
highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Sta in PAS level 0 or 1
and adjust from there.
Long press the “-” button to sta the Walking Mode. The e-bike will travel at 6 km/h (3.73miles/h),
easy to push.
Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your
bike. On a at suace, in a low gear (1 or 2), most riders should be able to begin pedaling the bike with
pedal assist level 0 or 1. You may also use the throttle to accelerate and maintain your desired speed.
The throttle is used by slowly and carefully rotating the throttle backward toward the rider. Do not use
the throttle unless you are on the bike. Do not use the throttle while dismounted. Avoid accidental
application of the throttle while dismounted; anytime you are moving the bike while dismounted,
ensure the bike is powered o to prevent the accidental application of the throttle.

The Cityrun employs 26"*2.5"rubber tires with inner tubes. The tires are designed for durability and safety
for regular cycling activities and need to be checked before each use for proper ination and condition.
Proper ination, care, and timely replacement will help ensure that your bike’s operational characteristics
will be maintained, and unsafe conditions avoided.
Even tires equipped with built-in, at-preventative tire liners, like those that come with bikes from
heybike, can and do get ats from punctures, pinches, impact, and other causes. When tire wear
becomes evident or a at tire is discovered, tires and/or tubes must be replaced before operating the
bike or inju to operators and/or damage to your bike from heybike could occur.
For more information on tire or tube replacement procedures, or questions about tire ination, visit
heybike.com/pages/help-center or contact Heybike Suppo.
heybike recommends 35-65 P.S.I for the stock tires on the heybike. Always stay within the manufactur-
er’s recommended air pressure range as listed on the tire sidewall.
It is critically impoant that proper air pressure is always maintained in pneumatic
tires. Do not underinate or overinate your tires. Low pressure may result in loss of
control, and overinated tires may burst. Failure to always maintain the air pressure
rating indicated on pneumatic tires may result in tire and/or wheel failure.
Inate your tires from a regulated air source with an available pressure gauge.Inat-
ing your tires from an unregulated air source could overinate them, resulting in a
burst tire.
Tire Ination and Replacement
When changing a tire or tube, ensure that all air pressure has been removed from
the inner tube prior to removing the tire from the rim. Failure to remove all air
pressure from the inner tube could result in serious inju.
Using aftermarket tires or inner tubes, not provided by heybike may void your
warranty, create an unsafe riding condition, or damage to your bike. If required by
law, ensure replacement aftermarket tires have sucient reective sidewall
striping.
