1. GENERAL
1.1 Welcome
We would like to thank you for your purchase of an NCM E-bicycle and welcome you to our fast-growing family of E-bike
enthusiasts. Bicycles offer unparalleled practicality and excitement, and our E-bikes at NCM are supercharged versions of
this amazing invention. As bikes have evolved so have we, standing at the forefront of innovation in E-cycling technology,
aiming to offer something new and thrilling while keeping and promoting the soul of cycling.
1.2 Use of the Manual
We encourage you to read this manual thoroughly before you take your new NCM E-bike for a ride. It is important not to
overlook the safety instructions and explanations of both traditional and non-traditional bike parts, as this will offer you a
general understanding of your new NCM E-bike. This manual is designed to help you get the most out of your E-bike, and
so we have attempted to answer as many of your potential questions as possible. Please take a moment to read through
the various sections before you get in the saddle.
1.3 Service and Technical Support
This manual is intended as a general overview of your new NCM E-bike, and is therefore not an extensive reference. For
technical support, including information about service, maintenance and repairs, please consult your dealer. You can visit
our website (www.ncmbikes.com) for more information about our products and technology, or to find a dealer close to you.
You can also email us your inquiries at [email protected].
1.4 Choosing the Right Size
An important consideration when selecting the size of your new bike is the stand-over clearance: the distance between you
and the top tube of the bike when you stand over it with your feet flat on the ground. For most bicycles, this distance
should be at least 1"(25 mm). If you are choosing a mountain bike, it is recommended to have at least 2"(50 mm) of
space. Your bike dealer can assist you in finding a bicycle with the correct dimensions for you.
Figure 1
H = stand-over clearance
Minimum: 1"for most bicycle types
2"for mountain bicycles
H
GENERAL

02
For some bicycles, like low-step cruisers, stand-over clearance measurement cannot be used as they either do not have a
top tube or it is sloped very low. For these bikes the height of the seat post should be used to select the correct size. You
should be able to touch the ground comfortably while sitting in the saddle when it is at its lowest point in the seat tube.
Adjusting the saddle can further improve the comfort, fit and performance of your bike.
The valid total weight of the electric bike states the load of the bike itself and the driver. Certain parts have their own load
limits, such as the rear carrier; please consult your dealer if you are unsure of the load limits of your bike’s parts.

1.6 Range
The range on one battery charge strongly depends on several conditions, such as (but not limited to):
● Road conditions, such as road surface and slope.
● Weather conditions, such as temperature and wind.
● Bike conditions, such as tyre pressure and maintenance level.
● Bike usage, such as acceleration, shifting, and motor assistance level.
● Weight of rider and cargo.
● Number of charge and discharge cycles.
1.7 Shifting Recommendations
For improved range, we advise shifting according to speed. For setting off and traveling at low speeds, a lower gear is
best. At higher speeds a higher gear should be chosen. Releasing pressure from the pedals while shifting will allow for
smooth support and improved range.
● High speed, high gear
● Low speed, low gear
● Reduce pedal pressure when shifting

SAFETY
2. SAFETY
2.1 Battery & Charger
● Keep the battery and charger away from water and heat sources.
● Do not connect positive and negative terminals.
● Keep the battery away from children and pets.
● Use the battery and charger only for their intended purpose as part of your E-bike.
● Do not cover the battery and charger, place objects on top of it or rest objects against it.
● Do not subject the battery and charger to shocks (e.g. by dropping).
● Stop the charging procedure immediately if you notice anything unusual.
In the unlikely event of the battery catching fire, DO NOT attempt to put it out with water. Use sand or another fire
retardant instead and call emergency services immediately.
Avoid contact with the battery and charger during the charging procedure; the charger heats up considerably.
Please take note of the additional information on the rear of the battery case.
2.2 Bike Usage
Try all settings on the E-bike and become accustomed to their various results in a safe and controlled environment before
you try riding the bike on the open road. Bicycles with pedaling support may handle somewhat differently depending on the
settings being used.
IMPORTANT SAFETY INFORMATION
1. Always wear a helmet while riding. Make sure your helmet complies with local laws.
2. Keep body parts and other objects away from moving bicycle parts which may cause you harm, such as the wheels and
chain. Do not rest any objects on the battery or motor. Do not impede the drivetrain in any way.
3. Always wear shoes that will stay on your feet and will grip the pedals securely. Never ride barefoot or when wearing
sandals.
4. Be thoroughly familiar with the controls of your bike.
5. Wear bright, visible clothing that is not so loose that it may accidentally catch on moving parts of the bike or be snagged
by objects at the side of the road or trail.
6. Do not jump with your bike. Jumping with a bike puts incredible stress on most components, such as the spokes and
pedals. One of the most vulnerable parts to jumping-related damage is your front fork. Riders who insist on jumping a bike
risk serious damage to the bike as well as to themselves.
7. Be mindful of your speed and keep it at a level which is consistent with conditions. Always keep in mind that there is a
direct relationship between speed and control, and also between speed and component stress.
8. Always follow local traffic laws.
9. Never ride while under the influence of alcohol, medication or drugs.
10. If you suffer from any health conditions, please consult your doctor before riding.
11. Never endanger yourself or others through reckless riding.
12. Please keep in mind that braking distance increases with imperfect road conditions, such as gravel or wet surfaces.
13. Please check the cable routing of the brakes before cycling. Ensure that both brakes are operational and in good
condition.
14. The e-bike is mainly suitable for rides on paved roads and paths. It is recommended not to use the e-bike for extreme
mountain tours with multiple climbs, as the system is not designed for these climbs due to the torque of the motor.
15. Failure to follow this instruction manual may result in serious damage to the bike. Keep the manual. If passing the
cycle on to a third party, it is essential that you include this manual along with it.

It is customary for countries with right-hand traffic to have the front brake on the left-hand brake lever and the rear brake
on the right-hand lever. The opposite is generally true for countries with left-hand traffic. The table below shows several
examples.
WARNING:
● Please follow local laws regarding age restrictions for cyclists.
● Please do not touch the hot surfaces after heavy use, such as the disc
brake rotor or V-brake rim side edge.
● When folding out the kickstand, always ensure that the stand is secure
and that the base is solid, so that a fall of the bicycle is prevented.

SAFETY
Child Seat and Child Trailer
Never carry a passenger. Installing a child seat on the bike is not allowed.
Please check with us before installing a child trailer on the bike.
Refer to and follow national and regional regulations on the use of child seats and child trailers.
Never attach a child seat to handlebars, seat, or front luggage carrier.
WARNING:
The weight of a child seat or trailer can affect the handling of a bicycle by altering the center of gravity, weight and
balance. Use of a child carrier or rack can result in a loss of control, resulting in serious injury and/or death.
Rear Carrier Rack Payload:
The maximum payload of the rear carrier rack is already engraved on the carrier. Please check if you want a more
detailed number.
Total Weight:
The valid total weight of the electric bike states the load of the bike itself and the driver. Individually valid is the information
printed on the sticker on the frame. See example below:
Inflating the Tyres
WARNING:
You should always check the tyre pressure before you start riding, or once a week at the minimum. Check the side wall of
the tyre for the minimum and maximum inflation pressures, and always ensure that your tyres are inflated to a pressure
within the indicated range. If the pressure is too low, your wheel may be damaged, or the inner tube may be pinched,
resulting in a flat tyre. If the pressure exceeds the maximum recommended number, the tyre may blow off the rim,
resulting in damage to the bike and injury to the rider and those nearby.
To ensure that you always have the correct and desirable tyre pressure, use a bicycle pump with a built-in pressure
gauge.

2.4 Keys
Each NCM E-bike comes with two copies of the battery lock key.
Bikes with rim locks are delivered with extra keys (not the same key as the battery). Onboard charging of the battery will
likely lead to infrequent usage of the battery lock key; it is needed for maintenance and repair, however, so please keep
this in mind when storing the key.
● Make sure to always have at least one spare key.
● Keep spare key(s) in a safe place for repairs, maintenance and emergencies.
● Please bring the key when going to your NCM dealer for maintenance or repairs.
2.5 Liability Disclaimer
You are responsible for your own actions while using an electric bike. NCM Bikes is not responsible/nor liable for any
accidents or injuries (whether caused by you or others) that may occur during your use. This is especially valid for cases
of ungranted modifications to the setup of the bike, e.g. tuning motor or electronic parts, replacing the brake systems or
other modifications that affect ride stability or safety. We recommend contacting your insurance provider to determine if
your current insurance policy would cover you in the event of an accident.

Do not make any further changes to the suspension fork.
WARNING:
To avoid discomfort, the saddle should generally be set as horizontal as possible.
There is a minimum insertion line marked on the seat post
(Failure to observe the minimum insertion line can result in
serious injury); please ensure the seat post is always inserted
into the seat tube beyond this line (the line must be inside the
seat tube).
- Loosen the quick release lever at the top of the seat tube,
determine the appropriate saddle height and tighten the clamp.
- The clamping force can be adjusted by adjusting the bolt on
the quick release lever.
- The quick release lever must be closed with considerable
counter pressure.
3.8 Brakes
3.8.1 General
In most countries, bicycles are made so that the left brake-lever controls the front-wheel brake; to change this, please
contact your dealer for help, Keep in mind Section 2- Important safety information.
If your bicycle has two hand brakes, apply both brakes at the same time for optimal stopping distance.

INSTALLATION AND ADJUSTMENT
3.8.2 Brake Adjustment
Disc brakes
When the wheel is out of the frame, do not operate the brake lever. With some brakes,
the pads automatically adjust their clearance such that you will not be able to re-insert
the disc.
Aligning a hydraulic disc brake
1. Loosen the two alignment bolts but do not remove them.
2. Slowly rotate the wheel and check the space between rotor and brake pads; adjust the
position of the brake pads so that the rotor is not rubbing and is slightly closer to the
outer pad (the clearance between rotor and pad should be just enough to prevent
rubbing). Make sure the rotor and pads are parallel to each other. Tighten the bolts when
the adjustment is finished.
WARNING:
If the disc rotor is curved or broken, please replace the rotor first.
WARNING:
Overuse or incorrect use of a front-wheel brake can cause the rear wheel to lift off the ground, resulting in decreased
control of the bike or even flipping the bike and rider in the forward direction; this can lead to serious injury and bicycle
damage. Be careful when applying the front brake, and avoid using it without also using the rear brake. Ideally, both
brakes should be applied at the same time, with the rider moving rearward on the bicycle depending on the amount of
braking pressure applied.

3.9 Shifter and Derailleur Adjustment
Rear Derailleur Adjustment
Step 1: Make sure the rear derailleur is shifted all the way down to the smallest
cog.
Step 2: Turn your barrel-adjuster all the way tight so that you have room to
adjust it later.
Step 3: Adjust the high limit by rotating the screw marked "H" on your derailleur
so that it lines up with that smallest cog.
Step 4: Tighten the tension in your cable by unscrewing the cable anchor,
pulling the cable tight, and screwing the anchor back on tight.
Step 5: Shift your rear derailleur to the 4th or 5th cog.
Step 6: To adjust the index, turn your barrel-adjuster so that the derailleur pulley
lines up underneath the correct (chosen) cog. With a Shimano rear derailleur,
you want to line up the pulley slightly inboard of the cog. Perform some practice
shifts to make sure it is adjusted properly.
Step 7: Shift your rear derailleur to the largest cog.
Step 8: Adjust the low limit by rotating the screw marked "L" on your derailleur
so that it lines up with the largest cog.
Step 9: Adjust the B-tension screw so that the pulley on the rear derailleur is as
close to the largest cog on the cassette as possible without dragging.

4. E-PARTS OVERVIEW
4.1 Explanation
NCM E-bikes are equipped with components that work together to give you a smooth, powerful and effortless riding feel.
Our pedal-assist system consists of the following:
Battery
NCM E-bikes’ integrated lithium-ion battery packs are some of the highest capacity packs available on the market, with the
NCM T7 step storing up to 960Wh of energy. The packs consist of high-density cells, meaning that our designs remain
sleek and light without any sacrifices to battery capacity.
Motor Powered by Das-Kit
With a reliable, compact but powerful X16 Das-Kit motor, you will always have the required assistance on hand when you
want it. Delivering a smooth and quiet ride at all assistance levels, this motor is perfect for helping the rider navigate busy
city streets as well as peaceful parks and nature areas.
Display
The Das-Kit control panel gives the rider full command over the electric system, and its simple setup provides all the
information you may need about your E-bike at the quick touch of a button, allowing you to spend more time enjoying the
world around you. The display provides the following information:
● Battery level indicator
● Support level indicator
● General indicators: speed, distance etc.
Throttle
The throttle is located on the right handlebar and propels the e-bike forward without having to pedal. When the throttle is
engaged, it will start the motor and help generate a speed boost.
When the customer steps on pedal, the force will cause the voltage change of the torque sensor. The higher the torque
force, the higher the voltage.
When the voltage is higher, the controller will increase the output of the motor.
When the voltage is low, the controller will reduce the output of the motor.
When the customer stops pedaling, the controller will stop the output of the motor.
The bike can also be used without electrical support from the motor; by setting the support level to 0, the E-bike will
behave like a traditional bicycle. An empty battery will not render your bike unusable.

4. Disconnect the charger from the AC outlet first and then from the battery.
5. Your NCM E-bike is ready for use.
4.2.5 Usage
When the battery power level drops to 1 bar, assistance from the motor will stop. If there are lights connected to the
battery, they will remain in operation for approximately two hours.
Remaining power in the battery can be checked by pressing the power button on the battery next to the LED indicators.
The handlebar mounted display will also indicate remaining power level when the bicycle is in use.
Perform a complete discharge of the battery (by riding your E-bike until the battery is completely empty) after 15 normal
charges or every three months; this will help increase the life of the battery. The charging time will be around 7 hours per
one time. Please do not charge the battery for more than 14 hours at a time (the battery will be fully charged much
sooner).
ATTENTION:
For 36V battery: fully charged voltage: 42V, low voltage: 31V.
For 48V battery: fully charged voltage: 54.6V, low voltage: 42V.
This means the customer needs to charge the battery when the display shows voltage no less than 31V or 42V
respectively.
4.2.6 Storage
If the bike is not in use for a period of longer than one month, it is best to store the battery:
● At 40%-60% of its capacity, charged once a month for 30 minutes.

If your missing item isn’t nearby, the Find My app can still help you track it down using the Find My network — hundreds of
millions of iPhone, iPad, and Mac devices around the world. Nearby devices securely send the location of your missing
device to iCloud, then you can see where it is in the Find My app. It’s all anonymous and encrypted to protect everyone’s
privacy.

4.3.3 FAQ
A. When can the device be located?
When an item is separated from its owner for a period of time, it can be found by other Apple devices that are part of the
Find My network, and the owner can start to get the location of the device.
B. How to confirm whether the device has been turned on?
Double-click the device button, the device will beep, and the light will flash three times, indicating that the device is
working. If the device does not ring, the device is off. Long press the button for five seconds to turn it on.
C.How is my privacy protected?
Only you can see where your item is. Your location data and history are never stored on the item itself. Devices that relay
the location of your item also stay anonymous, and that location data is encrypted every step of the way. So not even
Apple knows the location of your device or the identity of the device that helps find it.

D. What is the Find My network? And how does it work?
The Apple Find My network provides an easy, secure way to locate compatible
personal items on a map using the Find My app on your iPhone, iPad, iPod
touch, Mac, or the Find Items app on Apple Watch. Simply pair your compatible
product with the Apple Find My app to view it right alongside your Apple devices.
If your item ever goes missing, you can put it in Lost Mode to display a message
and contact information to anyone who might find it. The Find My network is
encrypted and anonymous, so no one else, not even Apple, can view its
location.
