1. ASSEMBLY INSTRUCTIONS
1.1 Carefully take the bicycle out of the box and remove all
bubble wrap and other protective elements.
If the box is badly damaged, please take pictures and contact us
immediately as we will use this to file a claim with the shipping
company IMMEDIATELY.
Open your HPC accessory box. In this box you will find your
pedals, charger box, rotor, rotor bolts, product manuals and any
optional accessories.
1.2 Look carefully inside the box for your pedals (L=left,
R=right)
“L” goes on the left side and “R” goes on the right side. MAKE
SURE YOU PUT THE THREAD IN
CORRECTLY. It is always advised to use a proper pedal
wrench to tighten the pedals properly. HPC will NOT be
responsible for stripped pedals. Right pedal has a traditional
right hand thread, while the Left pedal has a left hand thread.
1.3 Install Magura rotor onto front wheel hub. There are 6
rotor bolts. Pay attention to the rotor placement and line up the
arrow with the correct front wheel rotation (forward). Install all
6 rotor bolts crosswise, and do not fully tighten. Rotate rotor
clockwise, then tighten bolts to 4Nm.

1.4 (Optional) Install supplied fender. Using a 3mm allen key
(ball end recommended), carefully thread in the 2 snap-in bolts
into the lower holes on the rear of the arch and torque to 3Nm.
Once these have been installed these bolts do not have to be
removed. *Be careful to not scratch the stanchions during
installation.
Line up the fender with the snap-in bolts and press down until
secure. Fender will “snap” into place. BE SURE TO APPLY
PRESSURE OVER THE MOUNT BOLT AND NOT THE
TAIL OF THE FENDER.
Using a 3mm allen key, insert the fender mount bolt into the
center of the arch and torque to 3Nm. There should be no play
between the fender and the arch.
1.5 Slide the 15mm Axle through the drive side fork leg drop
out until it engages the threads of the non-drive side drop out
1.6 Use a 6mm hex wrench to tighten the thru axle. Torque
clockwise to 7Nm.
1.7 Install the handlebars. Use the four 5mm allen screws to
secure the stem to the handlebar to 9Nm torque. Alternate bolts
while tightening. Your brakes should be angled downward at
around 45 degrees, so they are comfortable to grab while you
are in your standard riding position.

1.8 Both Trailblazer and Trailblazer PRO feature an adjustable
dropper seatpost already installed. The seatpost should be
inserted all the way in. Make sure it is tightened with a 5mm
allen key to 5Nm.
1.9 Install the saddle onto the dropper post. Place saddle rails into
clamp, adjust angle and fore/aft position per bike fit, and tighten
bolts with 5mm allen wrench to 8-10NM
1.10 Make sure brake cutoffs are properly plugged in.
CAREFULLY make sure you plug in the connectors and follow the
white mark as your guide. Since these are not keyed, you must take
extra precaution
1.11 Configure the cockpit and clean up the wiring like in the
photo below. Use the supplied Velcro straps to keep the wires neat
and out of the way when you turn the handlebars

1.13 Make sure the display is plugged into the main wiring
harness. The green triangular connector on the 750W/1200W will
be by the handlebar and plugs directly into the back of the display.
The display connector for the 1600W can be found on the right
side of the headtube as shown.
Congratulations! Your assembly is complete!

2. Battery Safety (Brief Overview)
If you ever suspect a battery problem, please contact us immediately by email or phone so we can go
through the appropriate steps/procedures to make sure everything is okay with battery system.
At Hi Power Cycles, safety is our number one concern. We want our customers to enjoy a great product that will give those customers’
years of trouble free operation. As much effort as we do to minimize the risk of these state of the art batteries, there is always safety concerns
when it comes to Lithium batteries that we want our customers to be aware of. All of the new portable electronics, including cell phones and
laptops, contain lithium batteries which have the same chemical properties, although bike batteries are just on a much bigger scale. We make
every effort to have the highest quality battery cells and best battery protection (called a
BMS or Battery Management System) to minimize any risk associated with these high
power batteries.
We have gone through extensive research and testing to get the best electric bike
batteries in the world. The battery chemistry we use is the same that large car
manufactures (such as Nissan) use in their vehicles. This state of the art battery
chemistry is called Lithium
Nickel Manganese Cobalt (LiNiMnCoO2) or NMC for short. We felt that this is the best
overall combination of power, safety, performance, and life span compared to the other
options available.
Due to the nature of lithium cells, which have a lot of energy stored in a small
package, there is always a possibility this energy can be suddenly released and can cause
fire and/or serious injury if not taken care of immediately. With a state of the arm Battery
Management System that is found on all of our battery packs, the cells and pack are
protected from failure. The only time a pack will fail will be a result of a BMS failure and
attempting to charge, short circuit, over discharge, or somehow puncture the battery pack.
The main cause of failure in lithium batteries occurs during the charging
portion, when cells can be overcharged. This is the number one failure and can lead to batteries which vent and eventually release all of
their energy at once (or can even cause the battery pack to ignite on fire). Due to a BMS failure, cells can get out of balance and certain cells
may become overcharged as a result. This is why we always recommend monitoring the charging process in the extremely rare event
something should happen. Charging on a concrete floor, such as in a garage, away from debris and material is always recommended as a
safety precaution.

2.1 Safety Precautions:
We recommend keeping the following immediately accessible
where you charge your battery:
-Class D Fire Extinguisher: can be used in the event of a
lithium fire
-ABC Fire Extinguisher: If you cannot get a Class D, this will
do the job by preventing other materials around the ruptured
battery from catching on fire.
If your charger typically takes 4 hours to charge your battery,
but it seems to be taking much longer than usual, unplug the
battery and investigate. If there is a burnt smell, it is a failed
BMS or wiring issue which you should stop charging
immediately. Do not leave your battery unattended on the
charger.
If, for whatever reason, your bike suddenly has a loss of power
and you are not getting the same performance, STOP
IMMEDIATELY. Turn the bike off and inspect your battery
system. Smell for a burnt smell and inspect there are no melted
or shorted wires. This would be indicative of a shorted or failed
BMS which you will need to contact us directly to take care of.
If you notice that your battery system has a strange smell,
looks damaged, or is leaking, contact us immediately and we
will walk you through the appropriate steps to take in this
instance.
2.2 Catastrophic Failure
Although extremely rare, all lithium batteries are capable of
catastrophic failure if mishandled or treated. The following are
guidelines for a battery pack failure. Great caution needs to be
exercised during a catastrophic battery failure.
As soon as a problem is detected (battery is hissing, you
smell a burning smell, it is billowing smoke etc), take
battery system or bike outside immediately, away from all
structures and people, preferably on concrete (like a
driveway). Observe the battery pack from a safe distance to
see if it is a pertinent problem that needs to be addressed
immediately. Monitor the battery pack until the cells drop
below critical temperature and start to cool off. Contact local
authorities if necessary!
2.3 Battery Safety (In Depth)
Main reasons a battery pack will fail:
-Short-circuit
-Charging
-Forced over-discharge
-Excessive heat or incineration
-Crush, puncture, or disassembly
While we have designed our cells and batteries to be tolerant of
adverse conditions, these very active chemical systems have
limitations. Certain hazards are associated with exposure to heat
and its subsequent effects on sealed cells. These hazards
include the potential for cell venting, explosion, and/or fires.
The initial source of heat can be external (welding, soldering,
etc.) or internal such as heating caused by short circuiting,
excessive running currents for prolonged periods of time,
forced over-discharge, charging, or excessive mechanical
abuse. Specifically, mechanical abuse in the form of excessive
shock or vibration can result in case deformation, crushing, and
damage to the electrode materials.
Not guarding against these conditions may result in a hot cell or
a battery pack that could vent or explode.

The intent of this section is to provide a general knowledge of
how to handle cells and batteries that have been subject to these
adverse conditions. This document will focus on the following:
-
-Hot cells
-Leaking or venting cells
-Cells that have exploded
-Fires involving lithium batteries
The guidelines in this document are minimum recommendations.
Only trained and equipped emergency responders shall be allowed
to respond to a vented cell incident. Consult federal, state, and
local regulations for emergency response regulations.
Hot Cells
A hot cell is a condition that arises due to a short circuit of the cell
or battery, either internal or external. The cell/battery temperature
rises as the event continues which can lead to the cell reaching
critical temperature and the potential to vent or explode.
Vented Cells
It is unlikely that any lithium battery would explode.
These events are rare and are usually the result of an
abusive condition or misuse that raises the cell
temperature above its critical point.
In the event of a lithium battery explosion, a room
can quickly fill with a dense white smoke that can
cause severe irritation to the respiratory tract, eyes,
and skin. Precaution must be taken to limit exposure
to these fumes.
Response Procedure
-Monitor the temperature from a safe distance using a non-
contact thermometer or thermal imager
-If temperature monitoring equipment is not available, keep the
area evacuated and secure and do not handle the cell/battery for
at least 24-hours
-If the battery cools, continue to monitor until it reaches ambient
temperature
-Remove the battery from the area once it is cool
-Dispose of the cell in accordance with waste or recycling
protocols

Univeristy as a source of information!

3. How to Charge Your Trailblazer
* All Bikes are shipped at a USA legal 750 Watts or less, depending on where we are
Shipping the bike. Any power level above this, you must abide by all laws and ordinances *
3.1 How to Charge Your Battery
1. Make sure your charger is the correct voltage for your
country’s power requirement. USA buyers make sure
the charger is in 115v operation mode by setting the
switch on the back of the charger. European owners
make sure to select 230v mode.
2. Plug your battery charger into the proper wall outlet. Use
only the included AC power cord plugged directly into your
wall receptacle.
DO NOT ATTMPT TO USE ANY OTHER POWER
CORD TO CHARGE YOUR BATTERY AS YOUR
CHARGER USES SPECIAL HEAVY GAUGE WIRES TO
HANDLE THE CURRENT AND POWER REQUIRED BY
OUR POWERFUL CHARGERS.
DO NOT UNDER ANY CIRCUMSTANCES EVER
ATTEMPT TO USE AN EXTENSION CORD OF ANY
KIND.
Using a non-OEM supplied power cable or extension cord
may substantially increase internal resistance in your wires
and may cause wires to get dangerously warm and could pose
a hazard to you or your personal property.
3. One green light and one red light will light up when the
charger is first powered on
DO NOT LEAVE CHARGER PLUGGED INTO WALL
AFTER CHARGING. YOU MUST UNPLUG CHARGER
WHEN IT IS NOT IN USE.
4. Plug in the charger plug into the built in charge port on the
drive side of the Trailblazer frame as shown in the photo.
If it is operating correctly, you should see the charger light go
from one red and one green, to both red, and an audible fan
should kick in, indicating charging. Your charger will charge
quickly up to about 95% and then slowly charge the last few
percent as the battery self-balances each cell. Once charge is
complete, the fan will turn off, and one of the red lights will go
back to green.

Cycle Satiator Electronic Charger
If you purchased the Cycle Satiator electronic charger, your
charger has already been programmed for your bike! The three
profiles are written on top of the charger so you know which
profile to choose.
1. Plug in your Satiator to your outlet
2. Select charge profile you want to use (100%/90%/50%)
3. Hold the bottom button down to select
4. Plug the charger into the battery
5. Battery will start charging. The Satiator will indicate what
voltage the battery is currently at and how many amps it is
charging with.
Which charge profile should you use?
For most people, we recommend sticking to the 100% charge
profile for you normal, everyday rides.
If you want to maximize your battery life cycles and you do not
need the full range capacity for your ride, we recommend using
the 90% charging profile.
IMPORTANT: Do not use the 90% charge profile more
than 4 charge cycles in a row, you must do at least 1 full
100% charge for every 4 90% charges so the battery will
stay in balance.
Storage Mode
If the battery is low, and you want to store over the winter, use
the 50% charge profile. We recommend taking the battery off
the bike and storing it in a climate controlled environment.
In order to maximize storage life and performance, you will
want to charge the battery using the 50% profile and disconnect
it when it is finished.
Every 2 months, we recommend using the 50% charge profile
to top the battery off so it maintains a safe voltage for the cells.
It may charge for only a few minutes as most packs have
minimal cell drain. Make sure once it is done charging,
disconnect the charger from the battery.
Even though these are state of the art batteries with built in
Battery Management System, safety is always our number one
priority. It is always good to monitor these batteries when
charging and never leave these fully charged for more than
24hrs.
NEVER LEAVE YOUR BATTERIES CHARGING
UNATTENDED.
NEVER attempt to use a battery that is damaged or not
performing properly.
ONLY charge using supplied power cables and never use
extension cords to charge
Can you unplug your battery before it is fully charged?
You do not need to wait for a full charge, you can use your
batteries whenever, since they have no memory. With that
being said, for extended use, it will always be better to get a full
charge so that you do not deplete your batteries down too far
when you ride. It is better in the long run to use less than 80%
capacity the battery when riding if possible.

4. Installing/Removing Battery
TheTrailblazer features a quick change battery that take less than
10 seconds to change!
Your battery will arrive plugged in, inside the downtube of the
carbon frame. To remove the battery,
1. Insert the key on the left side of the battery tube
2. Rotate key clockwise to unlock the battery. The battery will
drop about 1 inch towards the top of the underside of the
downtube.
To reinstall the battery, just angle battery in the downtube at the
bottom of downtube, and make sure the bottom of battery is mated
it up to the locater tab. Then rotate the top of the battery until it
clicks securely into the frame and it looks like the photo to the
right.

5.1 Before You Ride
1) TAKE THE BIKE TO YOUR LOCAL BIKE SHOP
FOR FINAL TUNING AND ADJUSTMENT
HPC requires the bicycle to be tuned
professionally once you receive it
Note: We do get each and every one of our complete bikes
professionally tuned up prior to shipping. During shipping,
shifters, brakes and other mechanical parts may come out of
alignment. If you are capable, you are welcome to do it yourself
if you are confident in your abilities.
2) Make sure you battery is in the locked position. If it is not
locked, you run the risk of the battery falling off while riding
and damaging your battery. REMOVE YOUR KEY FROM
YOUR BIKE
3) Press the power button on the control console. Your bike and
computer display will turn on.
4) Use the up/down arrows to turn your display to level “0”.
Lift up the rear wheel and make sure the bike is operational by
using the throttle
5) Check both front and rear brakes for integrity. Your
hydraulic brakes should stop the bike with minimal effort
6) Learn the power delivery characteristics of the motor by
gently easing into the throttle and pedaling as you. There will
be a delay going from using the throttle back to pedal assist. It
is extremely important to assist the motor with your pedal
power under demanding situations such as hills or off-road
trails. *This is vital, especially in steep terrain*
7) ENJOY your new HPC e-bike! A lot of time and hard
work is spent on getting these bikes just right, so enjoy it!
8) When you are done riding, simply park it in safe,
preferably cool place, press the power button to turn the bike
off. If you are not going to use the bike for more than 2
weeks, use the key to remove the battery from the bike and
store in a cool/dry place. It is always best to store your
batteries at their nominal voltage, preferably 40-60%.
** Although wheels are professionally trued and
dished prior to shipment, you might need to have
your wheel re-trued after your first couple of
rides**

6.1 Riding and Maintenance Tips
1. If you do not wish have pedal assist active, start with the
electric system in level “0”.
2. Never shift under load! If you are in a pedal assist mode
and you want to shift your rear gears, slightly tap on
either brake lever (to activate the cutoff), shift to the gear
you want, pedal through so the derailleur shifts to the
correct gear, and then left of the brake and re-engage
pedal assist. If you shift under load you can severely
damage your chain and your derailleur.
3. Always start in your low gears (biggest rear gears 1-4)
for less stress on electronics and less wear and tear on the
bike
4. Make sure you are in the right gear for the right situation.
If you are climbing a steep hill, you want to be in the
lowest gear (largest ring on the rear cassette). If you
want to cruise on moderately flat terrain, leave it in the
middle gears. For pure speed and the least hill climbing
torque, the smallest cassette ring (or high gear) would be
appropriate but be advised that this will cause more stress
on the drivetrain and more stress on the electronics.
5. Make sure to keep your rear derailleur adjusted! Failure
to do so will increase the likelihood of chain skip which
will lead to poor shifting performance and potentially
damage your drivetrain.
6.2 Battery Care:
You have state of the art Lithium Batteries that have different
characteristics than SLA batteries. MAKE SURE TO CHARGE
IN A COOL, DRY AREA! If the batteries or charger get too
hot while charging (you
can’t hold your finger on either the BMS, battery, charger for
more than 5 seconds), immediately stop charging and check for
connection problems.
Standard charge time for our 12.4Ah batteries is approximately
4 hours with the 3A charger. When you are through riding your
bike for a while, always store your batteries in an
UNCHARGED STATE (40-60% of full charge capacity), you
will greatly prolong the life of your batteries. Only fully charge
the batteries when you will be using them soon after. Store
batteries in a cool, dry place, and where temperature does not
ever exceed 90 degrees F. That is pretty much all there is to it!
IT IS IMPORTANT THAT THE BATTERY CHARGER
GETS AIR FLOWING OVER THE HEATSINK AND IS
OUT OF DIRECT SUN TO AVOID OVERHEATING OR
BATTERY FAILURE
Long Term Storage:
We have designed these batteries and our bike system to be as
maintenance free as possible. In the event you will need to store
these batteries it is advised you store them with ~50% charge. If
you are storing them long term (for the winter) it is best to store
in a cool place and completely unhooked from your bicycle.
Every month it is advised to hook the battery up to the charger
for 5-10 minutes or so as the battery will lose charge over time
and this will allow you to put some extra charge in the battery
and balance the cells. We advise you keep the battery as close
to the nominal voltage of your system as possible (36V for
750W system, 48V for 1200W/1500W system)

6.3 Prolonging the Life of your Battery:
Your HPC bicycle features a state of the art Lithium based
battery system built right here in the USA. Our kits feature the
most powerful, lightest weight and best performing batteries on
the market. NMC based systems should expect around 3 years
of use depending on how you take care of your battery.
Remember that these batteries do have a shelf life so even if
you are not using the pack, the battery will only be good for so
long.
To prolong the life and performance of the pack, it is best to not
drain the pack to zero capacity (like when the battery
management system shuts it off). Going from 100% to zero
capacity will adversely affect your life cycles. It is much better,
for instance, to go from 100% to 50%. Keeping the depth of
discharge less than 80% (so from 100% to 20%) will make help
to extend the life of the battery.
Heat and discharge rate also will adversely affect the life and
performance of the battery. If you want more life from your
battery and system, it is best to use lower amps. The lower the
amps that the system drains from the battery, the less stress
(and heat) it puts on the battery cells and battery management
system. This equates to a longer cycle life and higher
performing battery. If you, for instance, use your system at full
throttle and high amps continually (like climbing long, steep
hills), you will notice a degradation of your performance and
range a lot sooner than someone who is not pushing the system
as hard.
6.4 Bike Operation:
1. DO NOT use FULL throttle for prolonged periods of time
if you are not in the correct gear for the mid drive motor. This
will result in excessive heat buildup in the motor, throttle and
batteries. Think about what would happen to your car if you
used full throttle in the incorrect gear for prolonged periods of
time... It will not last very long and put excessive wear and tear
on your drive train. Do not abuse your system, and it will last
you a long time!
2. DO NOT cruise long distances over 80% of the stated top
speed due to heat buildup in the components. For instance, if
you bikes top speed is 30mph, do not cruise over 24 mph. This
is a rule of thumb to prolong the life of your system.
3. NEVER fully rely on the motor for power when climbing.
Pedal along to assist the motor. This will increase range and
prolong the life of the components
4. DO NOT operate in excessive heat (over 100 degrees
Fahrenheit) for a prolonged period of time. Doing so may result
in excessive heat buildup and some components may shut down
due to thermal protection.
5. If you notice a decrease in performance or abnormal
operation, cease electrical operation immediately. Failure to do
so may result in damage to electrical components.
6. DO NOT apply the brakes abruptly when going downhill
as this may result in loss of control. Use consistent, gradual
braking.
8. NEVER use the throttle and brake at the same time. Doing
so will potentially damage the controller and the bike itself due
to the immense rotational forces of the motor.
9. ALWAYS help your system out by pedaling up steep
inclines. If you hear your motor struggling or your system is
going less than 5 mph at full throttle, either help out by
pedaling more, or simply get off your bike and walk it up the
hill. We will not be responsible for burnt motors due to willful
neglect.
10. Ride the bike at a level and speed you are comfortable
with. Do not push the boundaries of your skill level or the bike!
11. ALWAYS follow local laws regarding your electric bike.
If your bike is over legal power limits, bikes equipped with
bicycle computer must make sure to program your system to
federal legal limits when riding on public roads or property.

6.5 Storage and Charging:
1. ALWAYS store and charge your batteries in a cool, dry
place. Failure to do so will decrease performance and the life
of the batteries.
2. DO NOT store lithium batteries at a fully charged state
(40%-60% is ideal)
3. ALWAYS check motor is securely fastened to the bike’s
frame. Due to the incredible torque these motors can
produce, over time the motor may work itself loose. If the
motor is loose, take off external lock ring and use spanner
tool to properly tighten inner lock ring
4. ALWAYS check the integrity of the front and rear thru axles
to make sure the wheels are secured to the bike frame
5. ALWAYS check the integrity of the bike battery. Make sure
it is securely fastened to the frame. If you suspect excess
play, take the battery off the bike, inspect the rack for
damage and tighten the two M5 screws.
6. Check spokes on both wheels. The rear wheel often requires
more attention due to the torque of the motor. Spoke and
wheel maintenance are part of a normal bicycle
maintenance procedure and will be accelerated with an
electric motor. Do not take chances with the spokes and if
you think they are loose, chances are you are correct. The
spokes should all have the same tension. If they are loose,
tighten them yourself, or take it to your local bike shop to get
fixed.
7. Check the pressure in your tires. The required pressure can
be found on the sidewall of the tire. Normal pressure is 25-
30PSI. Tires lose an average of 2-3 PSI per week. Low
pressure will cause sidewalls to collapse, and that is how
most blowouts occur. HPC IS NOT RESPONSIBLE FOR
FLAT TIRES!
8. Check all electrical connections making sure that they are all
tight. Bad contact means energy is wasted as heat, which can
cause a breakdown of wire insulation. Any wire with melted
insulation indicates a poor connection nearby. Disconnect the
batteries and do not operate if insulation is melted or wire is
exposed.
6.6 Safety:
1. ALWAYS wear proper safety equipment
2. NEVER operate at speeds that exceed your ability to operate
the bike safely
3. ALWAYS know your surrounding and actively scan the
terrain for obstacles
4. DO NOT wear loose fitting clothes or articles
5. NEVER ride with more than 1 rider
6. Suitable for riders 18 and older. NO EXCEPTIONS!
7. Know your bike and personal limits
IF ANY INJURIES OR HARM OCCUR WHEN YOU USE
THE PRODUCT, THE MANUFACTURER OR
DISTRIBUTOR WILL NOT BEAR ANY RESPONSIBILITY
6.7 Getting the Stated Range out of Your System
In the electric bike world, most manufactures quote maximum
range at 20 watt hours per mile for an electric system. This is in
the BEST CASE SCENARIO in the real world, with little to no
pedaling. When giving our range estimates, we are talking
about a 170lb rider, totally flat ground, smooth surface, no wind
and cruising in the most efficient range of the system.
For instance, on our 750W system with 10.5ah battery, using
this calculation we would get 25.2 miles maximum range (48v
x 10.5ah = 504wh. 504wh watt-hours divided by 20 watt-
hours/mile = 25.2 miles range). Our range estimates are
slightly more conservative although many of our customers
frequently beat these range estimations.

If you are using pedal assist, especially in level 1 which is
approximately 40% of maximum power, you can get up to
twice this range.
If you are not getting the range, there are many factors at play.
If you are a heavier rider, it will adversely affect your range. If
you do a lot of starting/stopping on your ride, your range
numbers will plummet since accelerating takes the most juice
out of the battery. If you are riding on hills or rough terrain, you
will decrease your range number as the system will draw much
more battery juice under these circumstances. Tire PSI and
weather also can affect your range.
6.8 Using your E-Bike Computer
The HPC Trailblazer comes with an intelligent LCD display
which gives an abundance of information including: speed
relative battery level, trip, odometer, pedal assist level, and
current time.
-To enable walking mode, hold down the “-“ arrow which
will assist the bike up to 3mph if you need to walk it up a hill.
-The operation of the computer is very simple and you can
easily scroll through the different screens by short pressing
the power button
-The display offer 5 level of pedal assist which you can
choose by pressing the + or –buttons on the display. Each
mode (starting from level 1) will increase the amount of
power the motor will deliver.
-Pedal assist level 0 means there will be no motor
assistance given when you are pedaling.
-1600W models will have a special color DPC 18 display. It is set
up to read voltage instead of percentages of battery. 58.8V is a
fully charged battery, while around 42V it will be dead. Roughly
52V is 50% battery charge left.
6.9 USB Charging Capability
The DPC 18 color display found on the 1600W system features
a built in USB port on the bottom of the display. . In order to
use the USB charging function, start with the electric system
completely off, plug in the device you want to charge and then
turn on your system. Your devices will begin charging! (5V,

1. Always wear a helmet and protective gear while riding your
mountain bike. This includes a helmet, gloves, and knee and
elbow pads.
2. Stay within your skill level. Don't attempt trails or stunts that are
beyond your ability.
3. Keep a safe distance from other riders. This will give you plenty
of room to react to any unexpected situations.
4. Use hand signals to indicate your intentions to other riders. This
will help them to anticipate your movements and make it easier
for everyone to share the trail safely.
5. Stay visible to other trail users. Wear bright or reflective
clothing, and use a bell or horn to alert other riders of your
presence.
6. Check your bike before each ride. Make sure that the tires are
properly inflated, the brakes are working, and all other
components are in good working order.
7. Don't ride under the influence of drugs or alcohol. Riding while
impaired can impair your judgement and reaction times, making
it more difficult to ride safely.
8. Be prepared for unexpected obstacles. This includes roots, rocks,
and other hazards that are common on mountain bike trails.
9. Take breaks if you start to feel tired or overwhelmed. It's better
to be safe than sorry.
10. Follow the rules of the trail. This includes staying on designated
trails, yielding to hikers and other non-motorized users, and
respecting the environment.
On Road Riding Tips
1. Always wear a helmet and protective gear while riding your
electric bike. This includes a helmet, gloves, and knee and elbow
pads.
2. Keep a safe distance from other vehicles and pedestrians.
Electric bikes can go faster than traditional bicycles, so it's
important to give yourself plenty of space to react to any
unexpected situations.
3. Use hand signals to indicate your intentions to other riders and
drivers. This will help them to anticipate your movements and
make it easier for everyone to share the road safely.
4. Stay visible to other road users. Wear bright or reflective
clothing, and make sure that your bike has lights and reflectors.
5. Check your bike before each ride. Make sure that the tires are
properly inflated, the brakes are working, and all other
components are in good working order.
6. Don't ride under the influence of drugs or alcohol. Riding while
impaired can impair your judgement and reaction times, making
it more difficult to ride safely.
7. Learn and follow the rules of the road. This includes stopping at
all stop signs and red lights, and yielding to pedestrians.
8. Stay alert and be prepared for unexpected obstacles. This
includes potholes, debris on the road, and other hazards.
9. Don't overdo it. Take breaks if you start to feel tired or
overwhelmed. It's better to be safe than sorry.
10. Be wary of rain. Slick roads can make you susceptible to washing
out and can also damage your electronics

Battery Level Indicator
750W/1200W
The 750W/1200W Trailblazer come with the low profile DPC 240 display. This display features a battery indicator that shows
percent battery level which is simply based off the voltage. It is a relative gauge of how much battery you have left based on the
voltage of your battery.
When you are accelerating or going up a steep hill, a phenomenon call voltage sag (the voltage of the battery is lower under
load than at rest) will show a lower battery level than what you actually have. If you are using the bike’s power system, let the
bike sit idle for one minute and then look at the battery gauge to get a better indication.
1600W
The 1600W Trailblazer come with an advanced DPC 18 color display. This display features a battery indicator which is simply
based off the voltage and shows the current battery voltage. Because the bike is running a higher voltage 52V battery, you do
not want to pay attention to the battery indicator but focus on the voltage readout since that is the most accurate metric.
This is a breakdown of the battery % left when the bike is at rest:
100%- 58V
75%- 55V
50%- 52V
10%- 46V
0%- 42V
