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.
