Positioning the seat at the right height is key for better pedaling, safety, and overall comfo.
The rider’s leg length is used to determine the seat’s position. When pedaling, your hips should
remain level and your legs should not over-extend. To determine the right seat height, sit on the
eBike with the pedal at its lowest point and place the ball of your foot on the pedal. If your knee is
slightly at this position, the seat is at the right height. Additionally, when placing your heel on the
pedal, your leg should be nearly straight.

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.

Sta-up Procedure
After the bike has been properly assembled according to the assembly video, all components are
secured correctly, a ceied, reputable mechanic has checked the assembly, and you have read this
entire manual, turn on the bike and select a pedal assist level following the steps below:
Familiarize yourself with the batte power positions. Turn on the batte rst, then be ready for a
ride.
Ensure proper handlebar and seat adjustment. Note that lowering the seat so the rider can put
one or both feet at on the ground without dismounting from the seat may oer a safer and more
comfoable introduction to operating the bike. Ensure the handlebar faceplate bolts and seat
post quick-release are fully and properly secured.
Turn on the bike. With the batte locked in place. Locate the LCD display controls (near the left
handlebar grip). Hold down the power button for approximately 3 seconds until power is
delivered to the LCD display and turned on.
Select the desired level of pedal assistance (PAS) between levels 0 through 5 using the + and - on
the display remote. Level 1 corresponds to the lowest level of pedal assistance. 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.
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 throt-
tle while dismounted; anytime you are moving the bike while dismounted, ensure
the bike is powered o to prevent the accidental application of the throttle.
Turn on the headlight and taillight if needed. Once the batte is on, press button (located
on the light remote).

Notes: do not clean the bike with alcohol, gasoline, kerosene or other corrosive and volatile chemical
solvents to prevent dire damage. Do not wash the bike with a high-pressure water spray. During
cleaning, make sure that the bike turned o, the charging cable is unplugged, and the rubber ap is
closed as water leakage may result in electric shock or other major problems. When the bike not in use,
keep it indoors where it is d and cool. Do not put it outdoors for along time. Excessive sunlight,
overheating and over cooling accelerate the batte pack's life span.
1. Use original batte packs, use of other models or brands may bring about safety issues;
2. Do not touch the contacts. Do not dismantle or puncture the casing. Keep the contacts away
from metal objects to prevent sho circuit which may result in batte damage or even injuries and
deaths;
3. Use original power adapter to avoid potential damage or re;
4. Mishandling of used batteries may do tremendous harm to the environment. To protect natural
environment, please follow local regulations to properly dispose used batteries.
5. After eve use, fully charge the batte to prolong its life span.
1. Please t to store the bike in a cool and d place between 50 °F – 77 °F (10 °C – 25 °C). In
extremely humid environments the interior of the bike may suer condensation or even water
accumulation, which may damage the batte rapidly. Devices are not intended for use at elevations
greater than 2000m above sea level prolonged exposure to UV rays, rain and the elements may
damage the enclosure materials, store indoors when no tin use.
2. In daily use, t to avoid recharging the bike after completely exhausting the batte. If the
batte is low, charge it as soon as possible.
3. Please charge the bike eve other month to presee the batte.
Regular inspection and maintenance are key to ensure bikes from heybike function as intended, and to

connections can loosen. Always have a ceied, reputable bike mechanic peorm a tune-up on your bike after your
initial break-in period of 50-100 mi (80-160 km) (depending on riding conditions such as total weight, riding
characteristics, and terrain). Regular inspections and tune-ups are paicularly impoant for ensuring that your bike
remains safe and fun to ride.
The Ranger S employs 20"x4.0" rubber tires with inner tube. 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.
It is recommended 20 PSI for Heybike’s stock tires. Always stay within the manufacturer’s recommend-
ed 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-
ating 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.
