Welcome to Cyberbike
Introduction
Congratulations on your purchase of America’s most exciting new electric mountain bike– Cyberbike is
the Electric Bike That Shreds! While your Cyberbike includes the best warranty in the industry,
maintaining your bike is necessary for safety, and is entirely your responsibility. Your Cyberbike is a
machine, and with any such machine, hardware may loosen and components may wear out over time.
Therefore you must understand the fundamentals of how your eBike works, and you must maintain
your bike for your own safety. You should read and understand this manual completely before operating
your Cyberbike. IF YOU ARE UNFAMILIAR OR UNSURE, CONSULT A BIKE SERVICE
PROFESSIONAL BEFORE RIDING.
WARNING: When your bike is turned on, it is ON, so the torque sensor in the powerful, reliable, and
quiet Dapu motor will provide power if it senses movement in the pedal, which can happen easily. When
your bike is on– or any time– keep fingers out of any moving parts and be ready to operate and control
your bike. Your hands should be on the handlebars with fingers positioned over the brake levers.
Always turn off your Cyberbike when performing any service or maintenance.
Remember to always wear a quality helmet at the bare minimum, and other protective gear appropriate
for your type of riding. Specifically, trail or aggressive riding warrants a pair of gloves. We recommend
Kali Protectives.
Turning the Cyberbike on.
Touch the power button and your Cyberbike comes to life. It is now on and the pedal assist sensor
will apply power whenever the pedal is moved forward! Touching the power button again toggles
the display backlight on and off, and holding the power button down for 2 seconds turns the bike off.
Power is applied to the rear wheel via the drive chain through both your own pedal effort and
torque-sensing pedal assist of the powerful motor. Your bike will start at PAS (Power Assist Level) 1.
Your Cyberbike offers power settings of 0 through 5, from no pedal assist at Level ) to full Turbo Power
at Level 5. The higher pedal assist you choose the more power assist you will get, but at a more rapid
battery consumption. Always turn the bike off when you are done riding.
Operation

4
The LCD control panel display provides real-time information on PAS level, power consumption,
remaining battery level, voltage, along with a light status indicator and odometer/trip meters.
When controlled through the handlebar-mounted switchpack, you are able to access settings, toggling
between MPH and KPH for the speedometer, maximum speed at which pedal assist will be applied,
turning the display light and headlights on and off. Use the settings and controls as follows:
1. Power. To turn on touch the power button once. To turn your bike off, hold down the Power
Button for 2 seconds.
2. To enter the Settings Menu, hold down the Set Button for 2 seconds until the Settings menu
engages. Toggle through these settings by pressing the Set Button:
a. Reset Trip meters
b. Wheel diameter, do not change as his is set at the factory
c. Toggle MPH/KPH by touching the +/- buttons
d. Max PAS speed
3. Exit setting menu by holding the Set button for 2 seconds
4. To toggle display on and off, touch the power button once
5. Wheel diameter should be left as set at the factory, but if you accidentally change it, use “2199.”
6. To turn your headlight on (if installed) use the Light button
7. PAS levels are 0-5. 1 through five are the level of pedal assist. The higher the number, the more
available pedal assist power, and the more battery consumption. Likewise, a lower power level
will provide lower pedal assist level and longer range
8. Pedal Assist Level 0 is used to engage throttle (if installed) or “human effort only” riding.
9. Notes: The voltage indicator and bar graph will go down and then sometimes come back up as
you ride, this is normal. Don’t get range anxiety. Enjoy! When you get down to a constant one
bar indication you still have approximately 20% range. The voltage and bar graph may fluctuate
throughout the ride and this is not unusual.
Battery charging
Your battery is one of the most expensive components on your Cyberbike and should provide
many hundreds of charges. Proper care will ensure that you get the most life from your battery.
To charge with the battery installed, simply plug the charger into your battery using the round
charging plug, behind the waterproof seal on the lower left of the battery, and remember to
replace that seal when removing the connector. Do not store the bike for long periods with the
battery fully charged or uncharged as this will decrease the life of your battery. Never ride with
the key in the lock as this can damage the battery mounting mechanism. To remove the
battery, insert the key and turn to the LEFT. Carefully and firmly pull on the battery handle,
towards the left. The battery is heavy, don’t drop it or this may cause an internal breakage
or failure. Batteries damaged from hard impact will not be covered by your Cyberbike’s
2 Year Powertrain Warranty.
When the LED indicator on the smart charger unit turns from Red to Green, your bike is fully
charged. Your bike does not have to be fully charged to ride, but as with all rechargeable
batteries repeatedly draining the battery to zero will reduce the charging capacity somewhat.

5
The charging port is the plug behind the moisture seal in the bottom left of the battery. Your battery will
fully charge in approximately 3.5 hours from 10% to 100% using the included smart charger.
The USB port on your battery can be used to power certain devices.
The LED graph indicator on the battery will show at the push of the button the approximate level
of charge. Also reference your Cyberbike’s display screen.
Tires:
When we ride, the only contact point between us and the ground is the contact patches of the tires.
Consequently, tires have more of an effect on the ride characteristics and performance of our bikes
than any other component. This performance starts with tire pressure. Periodically inspect your tires for
wear and check the tire pressure. If you ride aggressively or get lots of flats, consider “going tubeless”
to reduce rotational mass and improve the handling of your bike. Check your Cyberbike model’s
specifications to see if your tires are tubeless ready, or consult your local bike shop.
Inflation. Proper inflation has a great effect on how your bike rides and performs.
a. Do not use a compressor unless it is regulated and you are familiar with the job.
Using a compressor can be dangerous and may very easily damage suspension
components, tires, and tubes. Use only appropriate pumps designed specifically
for bicycle tubes or shocks, and consult your local bike shop if you are unsure.
WE DO NOT RECOMMEND PRESSURIZED FILLING CARTRIDGES.
EVER.
These can be dangerous and are not worth it, There are mini-pumps
which have no chance of ripping a hole in your cornea. Screw those
things. Just our opinion.
b. Your eBike’s range, top speed, acceleration and tire wear, along with handling and
suspension performance are all impacted by tire pressures. Too high or too low tire
pressures can result in more flat tires. Full time pavement riding requires higher

6
pressures, and full time trail riding requires lower pressures. Your body weight, and
riding style are also considerations.
The right tire pressure depends on you
Your perfect tire pressure is something that is unique to you, the rider. However, in order to find
your perfect tire pressure, you have to consider several factors:
Your weight
A rider’s weight influences their tire pressure the same way it influences their suspension – a
lighter rider can get away with running less pressure and a heavier rider will have to run slightly
higher pressures to get the same result.
The trails where you ride
The terrain you ride will have a massive effect on your perfect tire pressure. If you mainly ride
smooth hard packed flow trails then you can get away with running slightly lower pressures,
provided your tires maintain their shape through the corners. If you frequently ride rocky trails,
you’ll want higher pressures to protect your tires and rims.
How hard do you ride?
Your riding style also plays a part here. If you find yourself “catching air” and running
aggressively over obstacles, you should run slightly higher pressures to protect your
components. If your riding style is a little more precise, you may benefit from the extra grip,
stability, and comfort gained by running lower pressures. Tires are a part of your suspension
and getting the air pressure correct will help your whole bike perform better- from
suspension, to handling, to traction, to braking.
Baseline Recommendations
The chart below is recommended pressure only as a baseline. Actual, proper pressures for your
personal ride will depend upon personal preference, weight, riding style, terrain, tires, and weather
conditions. The below chart is only a basic guide from which you should derive a conclusion based
upon all of these factors:

Care, Maintenance, and adjustments
Wheels and axles
Periodically check the tightness of all spokes and axles. Adjustments are not uncommon and
may be necessary for the continued performance and safety of your Cyberbike. Check your bike
every time you ride and throughout the day when riding aggressively or offer rough trails. You will soon
become familiar with and accustomed to the areas that require regular and/or periodic attention.
To ensure the proper tightness of Skewer axles:
1. Start with the lever open and facing towards the front and downward.
2. Holding the lever, loosen/turn the nut on the other side counterclockwise 2 - 3 turns.
3. Close the lever. It should be very easy, and the wheel is not properly attached.
4. Turn the nut clockwise until finger tight
5. Open the lever.
6. Tighten the nut clockwise one turn.
7. Close the lever. It should be quite firm. You are clamping your wheel on and in a position to
operate the brakes and cover terrain without falling ff, so this is very important! IF YOU ARE
UNFAMILIAR OR UNSURE, CONSULT A BIKE SERVICE PROFESSIONAL BEFORE RIDING.
8. If the lever is too hard to close, back the nut off a small amount and try again.
9. If the lever is too loose, tighten the nut up a small amount and try again.
The QR lever should always point backwards and/or upwards. That makes it less likely to catch on
anything and be pulled open or throw you off the bike.
Adjustments, adjustments, and more adjustments:
eBiking is incredibly fun. Once you’ve gotten familiar with the basics, make your rides even more fun
and rewarding through the many adjustments and modifications available to you. Make your Cyberbike

8
YOUR Cyberbike by adjusting the controls, brakes and suspension components in many different ways,
or replacing components with upgrades that more perfectly suit your riding style.
Brakes
Cyberbike Mullet and Frisco models all come with the high performance Tektro E350 hydraulic
brake calipers. These are seriously good brakes. Familiarizing yourself with the operation of
your brakes before you ride is essential. Your bike may have the front brake lever on the right
handlebar lever, or the left, with the other lever controlling the rear brake, depending upon
which version of the Cyberbike you have. Brake operation is arguably the most important
aspect of your bike, so your brakes must operate properly and be checked regularly.
Remember, brakes do a lot of work so they are not perfectly silent. You must have the wheel
and brake calipers adjusted properly for the most safety and for best performance from your
eBike. BRAKES ARE CRITICAL! IF YOU ARE UNSURE OF THE OPERATION AND
ADJUSTMENT, YOU MUST CONSULT A PROFESSIONAL BICYCLE MAINTENANCE
TECHNICIAN.
Adjusting Position of Brake Levers, shifter and display:
Control adjustments are best done while seated on or standing alongside your eBike.
1. Adjust your handlebar sweep, forward or back:

9
Adjust your shifter (right) and brake lever positions up and down (left and right bar):
Adjust the brake lever position. Too close and it will hit the bar before fully engaging brakes,
too far and it will be difficult to reach:

10
After rotating the handlebar in the stem, adjust the position of the brake levers, shifter, and
display control module on the bars, and adjust the reach of the brake levers for your own
liking. You may loosen, adjust, then retighten the pinch bolts and clamps which hold on your
grips, levers, control head (power and settings buttons) display. Adjusting your “cockpit” to
fit your size and comfort zone is important to maximizing your control of your
Cyberbike! Make sure you tighten everything back up before riding! Remember if
mounting Cyberbike aftermarket accessories including cell phone holders, lights, or other
accessories on your handlebars to make sure they’re adjusted properly to not move around.
This may result in distractions or crashes.
Brakes:
Remember, some sound from the brakes is normal. Only clean the disks with alcohol or
another suitable disk cleaner. Worn or contaminated pads may need to be replaced to improve
your performance or quiet a persistent squeak.
Adjusting Brake Calipers:
If your wheel is mounted and tightened correctly and straight, and you get what seems to feel
like intermittent rubbing on the disk, the slotted mounting points on the brake calipers allow you
to loosen the caliper mount slightly, engage the brake lever, and position the caliper to clear
the brake disk slightly between the brake pads and either side of the brake rotor. Tighten and
recheck for alignment. A little rubbing is natural, especially when new, but if you hear a coarse
or grinding sound when the wheel turns, immediately check this important system and do not
ride until you are certain it is adjusted and operating correctly- AND ALL HARDWARE IS
PROPERLY INSTALLED AND TIGHTENED. See these adjustments in your Cyberbike
Assembly Manuals. IF YOU ARE UNFAMILIAR OR UNSURE, CONSULT A BIKE SERVICE
PROFESSIONAL BEFORE RIDING.
Your Riding Position, Refined
Finding your “just right” riding position will greatly improve your comfort and control. How your
bike came from the factory is only your starting point on a quest for your perfect riding position!
There is nothing more customizable on your Cyberbike than the position of your handlebar and
controls. Among the myriad adjustments and changes you have:
1. Steering tube height. This is the tube in the center front of your Cyberbike that comes
up from the forks through the steering head. From the factory there will be a number of
spacers which can be removed and the fork/steering tube cut down for a more
aggressive riding position. You may also add a riser for a more upright riding position.
2. Steering stem length. This is the bracket that holds your handlebar to the steering
tube. These are short or long and sometimes adjustable within a certain range.

11
3. Bar width. Your handlebars may be long enough to cut down if there is too much
pressure on your shoulders or wrists. Thios an area of personal preference that varies
among riders.
The steering tube height, stem length, and handlebar width are meant to be modified to your
personal preference. Again, finding the “just right” riding position will greatly improve your
comfort and control.
Your head tube/steering tube is left high from the factory, but you can cut it- or have your local
bike shop cut it- and remove spacers to your personal preference.. Remember, once you cut it
down you can’t get it back so have your bike shop help fit you for the right steering tube stem
height.
Using a shorter stem gives the bike quicker handling characteristics and a more responsive
feel. This will give you more leverage and make steering quicker, but for some riders this may
be too “twitchy.” A longer stem shifts your body weight towards the front of the bike and puts
you in a better pedaling position, especially on those steep climbs.
Handlebar width and height is a personal preference and can result in much improved comfort
for you, especially on longer rides. A shorter or longer reach may put weight on or off your
wrists; a narrower grip may be more comfortable, or a wide grip may l provide you with more
control in tough terrain. You will find that all of the above adjustments can combine to make
your Cyberbike the perfect bike for you!
Suspension.
Cyberbike models come equipped with high quality suspension components from Suntour,
Rockshox, EXEform, and Sträva. These components may be adjusted to fine-tune your eBike
to perform best for you and the way you ride. These adjustments vary by model, and may
include spring preload (air pressure or mechanical spring), compression damping, and
rebound damping. Research to learn what effects these adjustments may have on your eBike’s
performance. Basic adjustment practices are provided here. (Some suspension comes with
an O Ring to use as a guide for how much suspension travel is being used or to set
“sag.” The O Ring you see on the stanchion tubes is supposed to be there and not a
part of the shock that is falling out!) If your shock or fork doesn’t have an O Ring, you
can use a zip tie. A little liquid on the stanchions when new is generally assembly
lubricant, but of course your shocks should not leak. DO NOT OVER PRESSURIZE AIR
SUSPENSION COMPONENTS AS THIS MAY RESULT IN BLOWN SUSPENSION SEALS.
Only use a proper suspension pump from companies such as Bontrager or a quality bike pump
can sometimes work. Do not use a high powered compressor because you will likely
blow out seals.

12
Available adjustments:
Frisco
Front fork: Suntour spring preload only (left knob) with lockout (right knob)
Rear Shock: EXAform A5. Adjust your air spring for your weight and riding style. We
recommend no more than 150 psi, although the manufacturer recommends up to 180 psi. Do
not not use a powerful compressor unless it is equipped with a regulator! It is best to use a
shock valve-specific pump such as those offered by Bontrager and others. It is easy to over
pressurize and consequently damage your air shock.
Mullet 2927
Fork:
Rockshox Recon Fork Coil Spring. Left knob offers spring preload; right knob controls lockout,
and the right bottom tube adjustment is for compression damping. Rockshox “Trailhead” App is
a manufacturer’s tool for dialing in your setup.
Rear Shock:

13
Rockshox Monarch. Your Monarch rear shock has 2-position compression adjustment
(open/lock) with external rebound adjust, highly tunable DebonAir™ spring offers a coil-like
consistent feel throughout the travel. A label on it that tells you to not inflate to over 275 psi.
That, from our experience, is an insanely high pressure. Start low and then add pressure until
you feel your suspension providing you the necessary firmness for your type of riding and the
terrain.
Setting “Sag.” Source: REI
Measure Static Travel
Start by measuring and noting the length of both the front and rear shocks in millimeters. You'll
use these numbers later.
Next make sure the shocks are switched open or are in descend mode. To make the next
steps easier, find a bench or tree to lean against or have a friend handy to hold your bike
steady.
Check both stanchions on your front fork for an O-ring. If you don't have one you can attach a
zip tie to show how far the stanchion travels. It's important to set sag according to your riding
weight so make sure to wear all your normal riding gear.
Now sit on the bike and bounce the suspension up and down several times to warm up the
shocks. Get into your riding stance with all your weight over the bike then slide the O-ring
down the stanchion on the fork and up the shaft on the rear shock. Carefully dismount the bike
without bouncing the shocks. Now you can measure and record the distance between the
O-ring and the body of the shock. This measurement is the shock’s static travel.
Set the Sag
To calculate your sag percentage, divide the static travel by the total length of the shock and
multiply by 100. Most manufacturers recommend that you set your sag somewhere between
25 to 35 percent. If your sag is higher or lower than that, you need to make some adjustments
by attaching your shock pump and increasing or decreasing the air pressure in the shock and
running the calculation again.
Sag is mostly a matter of personal preference, but if you ride fast over aggressive terrain, you'll
want to keep your sag lower and on the firm side by adding air pressure. For a smoother ride
on easier terrain, go for a softer setting by keeping the air pressure lower and the sag higher.
Each time you change the pressure in the shock, repeat the measuring process until your sag
is just where you want it.
Derailleur and shifter:

14
Most mass-produced Cyberbike models come with Shimano derailleurs. In any case, and in
addition to the information provided here, the manufacturer of these parts and many third party
sources provide a litany of information which is readily available.
The Shimano Altus and Deore SLX gear changing systems are precise and durable systems
which can provide many years of high performance use. Note that periodic adjustments,
cleaning, and lubricate will help to maintain the high performance shifting these systems
provide. Note the Deore SLX system comes with an on and off clutch tensioning switch.
For riding, use the “ON” position and use the “OFF” position for removing the rear
wheel. (Ships from factory typically in the “OFF” position)
Reflectors:
Check your local requirements. Generally, bicycles must have a colorless front reflector,
recessed colorless or amber reflectors on the back and front sides of the pedals, and a red
reflector on the rear. They must also have a reflector mounted on the spokes of each wheel, or
reflective front and rear wheel rims or tire sidewalls. Your Cyberbike may or may not have
shipped with the reflectors required by your local ordinances. If you are riding at night, please
use appropriate lighting equipment, it may be required by law where you ride.
Pre-ride checklist and other notes:
Rear derailleur adjustments can be found online or your bike shop can help you with this.
Make sure your pedal and all other hardware is secure whenever riding.
Keep your motor dry. Submerging or exposing your motor to heavy moisture will void the
warranty.
Please check the condition and air pressure of your tires before every ride and during the day
when riding hard or on rougher terrain. Remember higher air pressure will make your bike go
faster and extend the range but may result in popped tubes. Many Cyberbikes come with
tubeless ready tires which are more resilient to impact and sharp edges because there is no
risk of a pinched/punctured tube.
Warranty and Return Policy.
All terms and conditions are subject to retroactive revision at any time and without notice
(sorry, the lawyers wrote that).
