OWNER’S MANUAL

We want to thank you for purchasing a Bakcou eBike and would like to
welcome you as one of our newest Tribe Members. We know that you
are going to love your new eBike as much as we love ours and it will no
doubt change the way you access the backcountry!
We want you to know that customer service is at the center of our
business model. We encourage you to email, call, or use the online chat
on our website to contact us with any questions, concerns, or assistance.
We are committed to the design and manufacturing of the best electric
bicycles, bicycle components, and related products on the market. To
ensure that our bikes are of the highest quality we are uncompromising
in our choice of materials, manufacturing processes, development of
new products and commitment to innovation.
Our company was founded on a few basic principles. First, was our love
for the backcountry and the desire to access these remote areas with
minimal disturbance to wildlife and their habitat through quiet and non-
pollutant means. Second, was to design and build the most durable and
efcient, yet affordable, electric bikes on the market. Our goal wasn’t
to create a mountain bike conversion kit by simply adding a motor to a
bicycle frame that wasn’t designed and intended to operate with one.
Instead, we designed the eBike around the motor and the drive train
with the necessary framework and durability needed to withstand the
abuse and demands placed on it. Third, Bakcou was built by sportsmen
and outdoor enthusiasts for those that want the same thing we do,
which is to climb higher, go farther, and explore more without
adding stress to the environment.
Welcome to the Tribe. Now get out and enjoy the backcountry,
like you’ve never done before!

An electric bicycle can be a great way to access terrain that may be impossible by any other means. It can
also be dangerous, especially if you ride terrain above your ability or beyond the capability of the eBike
itself. If you are headed into the backcountry, be prepared. Bakcou recommends riding with a rst-aid
kit and a Trailside Repair Kit that includes a bicycle pump, at repair kit, chain links, chain tool, and bike
multi-tool. Bring water, food and clothing appropriate for the season and the environment. A dry trail with
good traction may turn impassable with a little rain. If this occurs, you may need to walk the eBike. Always
practice proper backcountry safety protocols.
The eBike will not protect you in an accident. There are no seat belts or air bags, and therefore a crash,
even at low speeds, can result in injury or death. If you are in an accident, inspect the eBike thoroughly
before continuing with your ride. If you aren’t sure, do not ride the eBike. Take it to a professional bicycle
mechanic or repair shop for a professional inspection.
If you experience any mechanical problems while on a ride, immediately turn off the electric power at
the battery prior to attempting any repairs. Repairs include anything such as putting the chain back on,
adjusting brakes, or adjusting accessories. Attempting to replace or re-engage the chain while the power
is on could result in serious injury.
Secure all cargo and ensure loose straps are secured to avoid interference with the moving parts on
the eBike. Be aware of loose clothing, especially on the drive side (right side) of the bicycle, to avoid
interference between your clothes and the drivetrain. Be sure the wheels spin freely and there is nothing
that could get caught in the spokes or prevent the wheels from turning freely. If you get a piece of clothing
or equipment caught in the front chainring, immediately turn the power off. You may need to be prepared
to cut or remove clothing that gets caught in the drivetrain in order to remove it from the system.
The Bakcou eBike is a fun and exciting ride! Always be aware of your surroundings and your environment.
Be cautious of other riders and pedestrians. Always stay in control and within your ability. Bakcou
recommends the use of a DOT (Department of Transportation) rated helmet at all times.
FOREWORD ON SAFETY

VISIT US AT BAKCOU.COM | 3
Your Bakcou eBike comes with a tremendous amount of torque and power. It is equipped with gearing
for steep climbing, as well as higher speed straightaways. The larger cogs, on the rear cassette, are for
climbing and the smaller cogs, are for atter ground and higher speeds. This makes riding your eBike
correctly, even more important. Sometimes riders get caught up in “throttle only” riding, to such a degree,
that they forget to shift gears. Similar to driving a car, it is important to shift into the appropriate gear for
the terrain you are riding. As with driving a car, you certainly wouldn’t start from a standstill in 6th gear.
This would cause a tremendous amount of stress on your drivetrain. An eBike is no different. Make sure
your eBike is in 1st or 2nd gear when you start off, and then shift into higher gears, as you pick up speed.
Then, as you prepare to stop, down shift into 1st or 2nd gear, so that you are once again in a lower gear
for when you take off.
Just to be clear, the largest cog on the rear cassette is 1st gear and is thus for climbing, and the smallest
cog is 9th gear and is for atter ground and higher speeds. The signicantly increased torque, created by
your electric motor at take-off, can be easily distributed across a large cog. Whereas, a small cog does not
have enough teeth to appropriately distribute the increased torque. Starting in a higher gear will cause
premature wear and tear on your chain and gears, among other drivetrain components.
In addition to the proper shifting described above, we strongly encourage using pedal assist to start rather
than throttling from a standstill. Using the throttle at a standstill is similar to pushing the gas pedal to the
oor in your car when taking off. While this may create some excitement, it’s also very stressful on the drive
train components of your eBike.
You will notice while riding that your eBike has shift and brake sensors. For obvious reasons, the power to the
motor is cut off when the brakes are applied. However, power to the motor is also cut while shifting gears.
This sensor allows for tension on the chain to be relieved so that proper and smooth shifting can occur.

TIRE PRESSURE
Pump tires to desired pressure. The range for the tires is from 5 psi to 30 psi, with 5 psi being the lowest
the tire is rated for. Lower pressures can provide more traction, however increase the risk of pinch ats,
and decrease the range of the motor. Higher pressures can decrease the possibility of pinch ats, but
also can decrease grip on softer and varied terrain. We recommend using a 2 psi difference between the
front tire and rear tire (+2 psi in the rear tire) to maximize traction in the front and stability in the rear, for
example 15 psi front, 17 psi rear.
If you are riding in an area with a lot of thorns, we recommend puncture proof tire liners and/or a
tube/tire sealant.
POWERING THE UNIT ON

LITHIUM ION BATTERY
The battery typically has a partial charge straight from box. We recommend fully charging your battery
prior to initial use. Your battery can be charged while on your bike, or it can be charged off your bike.
To charge the battery, remove the circular rubber plug from the LEFT side of your bike. Plug the charger
into a power outlet and wait until the light on the charging unit is illuminated red. Plug the other end of
the cord into the battery. The light will change to green once it’s fully charged. Allow approximately 4-8
hours for a full charge (depending on battery size). Always charge in dry, ventilated conditions away from
sunlight, ideally 50-80 degrees Fahrenheit.
To remove the battery from your bike, insert your key, turn it 90 degrees and pull the battery out.
During normal use, you can charge it after every ride regardless of battery level, there is no battery
memory and therefore consistent charging won’t damage the battery. For safety, the charging unit will
automatically stop charging once the battery is full. It’s never good to completely run the battery dead.
The charger will get hot, so make sure to keep it away from all ammable materials and surfaces. Only use
the original charger, DO NOT use any aftermarket chargers or charging accessories.
For long term storage, it is best to leave the battery at about 50%-80% (2-3 lights) state of charge (SOC).
Always store the battery in a cool place. For best results, do not store for longer than 4 months
without cycling the battery.

RIDING TIPS TO MAXIMIZE YOUR BATTERY
To increase battery life and reduce wear on the
components, follow these tips:
» Use the pedals as often as possible, especially
when starting.
» DO NOT simply rely on the throttle for power.
» Start in a low gear and low power. This means
looking ahead, and possibly shifting to a lower
gear before coming to a stop so you are in the
right gear to resume riding again.
» Use low gears for climbing steep hills. Avoid
putting unnecessary torque on the transmission.
» Minimize starts and stops by looking ahead and
planning your route.
» Use higher tire pressure.
In the rst 20 miles or so, the cables and system
components will settle and therefore may need to
be adjusted. If you are unfamiliar with adjusting the
derailleur, Google, “Derailleur Adjustment Video”
or reach out to your local bike shop for help.
HOW TO ADJUST THE FRONT SUSPENSION FORK
The dial over the right fork is to lock out the fork.
Turn clockwise to lock suspension travel. Turn
counter-clockwise to unlock suspension, and allow
the suspension to travel.
The cap over the left fork covers a valve to adjust
the pressure in the air forks. Use a high-pressure
shock pump to adjust the air pressure. (Given the size
of the valve, do not use a compressor or any other
type of pump). You may purchase a shock pump at
www.bakcou.com on the Accessories page.
Recommended air pressure is 140 psi and then
adjust accordingly to rider weight, terrain and
personal preference.

IMPORTANT SAFETY INFORMATION
Read this important safety information before riding your ebike.
AN EBIKE CANNOT PROTECT YOU IN AN ACCIDENT
The most common cause of injury on an eBike is falling. In a crash or impact, it is not uncommon for your
eBike to sustain damage and for you to fall. Cars have bumpers, seat belts, air bags, and crumple zones.
eBikes do not. If you fall, your eBike cannot prevent injury. If you are involved in any kind of impact, crash,
or accident, check yourself thoroughly for injuries. Then have your eBike thoroughly inspected by a local
bike shop before you ride it again.
KNOW YOUR LIMITS
An eBike can be dangerous, especially if you try to ride beyond the limits of your ability. Know your skill
level and don’t ride beyond it.
KNOW YOUR EBIKE’S LIMITS
Your eBike is made to withstand the stress of rough, rugged conditions but within “normal” riding
conditions. If you misuse your eBike by riding outside those conditions, it can be damaged by stress or
fatigue. Any damage can drastically reduce the life of the frame, fork, or other parts.
HANDLE WITH CARE
Some parts of your eBike can injure you if mishandled. There are sharp points, for example, on the teeth
of the chainrings and some pedals. Brakes and their parts get hot. Rotating brake rotors can cut skin and
even break bones. Clamps and pivoting parts such as brake levers can pinch, as can the chain where it
runs onto sprocket teeth. eBike components are especially vulnerable. Electric cables, connectors, battery
dock, battery, and the controller can be easily damaged if handled incorrectly.

VISIT US AT BAKCOU.COM | 11
LIFESPAN
An eBike is not indestructible, and its parts will not last forever. Our eBikes are made to withstand the
stress of “normal” riding because those stresses are well known and understood.
However, we cannot predict the forces that might occur if it is involved in an accident. With damage, the
life of any part can be drastically reduced and may fail without warning. The life of a part is determined
by its construction, materials, use, maintenance, rider weight, speed, terrain, and environment (humidity,
salinity, temperature, etc.), so it is not possible to give an accurate timetable for replacement. Any
crack, scratch, or change of color in a high-stress area indicates the part (including the frame or fork)
has reached the end of its life and should be replaced. If you are not sure or you don’t feel comfortable
inspecting or repairing your eBike, consult your local bike shop. Regular maintenance, frequent
inspections, and frequent replacement of parts are necessary for a high-performance eBike.
THINK SAFETY
Stay tuned to your environment and avoid dangerous situations which are usually obvious (trafc,
obstacles, drop-offs, and so on) but sometimes are not. Many of those situations are shown in this
manual. Some of the high-risk stunts and jumps seen in magazines or videos are very dangerous; even
skilled athletes get severe injuries when they crash, and they do crash. Modications to your eBike
can make it unsafe. Each part of your new eBike has been carefully chosen and approved. The safety
of accessory or replacement parts, and especially how those parts attach and interface with other
parts of the eBike, are not always apparent. For this reason, you should only replace parts with original
equipment or parts that are approved. If you are not sure what parts are approved, ask your bike shop.
Some examples of modications include physically altering existing parts (sanding, ling, drilling, etc.),
using adapters for brake systems, installing accessories, and changing parts.

For the most possible enjoyment from your eBike, familiarize
yourself with the pedals, brakes, shifting, and suspension. You
will enjoy yourself more if you are condent with your eBike.
BEFORE EVERY RIDE
Before riding your eBike, perform a safety check on level ground
and away from trafc. If any part doesn’t pass the safety check,
x it or have your eBike serviced before riding.
PRE-RIDE CHECKLIST
CHECK THE HANDLEBAR
1. Make sure the bar is at 90 degrees to the wheel.
2. Check that the handlebar is tightened sufciently so that
it will not twist out of alignment and does not rotate in
the stem.
3. Make sure that no cables are pulled or caught when you
turn the handlebar from side to side.
ADJUST YOUR HANDLEBAR AND STEM
Handlebar position is important for control and comfort. Special
tools and training are necessary to align, adjust, and torque your
stem, so only your eBike shop should do this. Do not attempt
to make the adjustments yourself as these changes may also
require adjustments to the shift levers, brake levers, and cables.
CHECK THE SADDLE AND SEAT POST
1. Make sure the saddle is in line with the center of the eBike.
2. Check that the saddle rails or collar is tightened sufciently
so that it will not twist out of alignment or move up or down.
ADJUST YOUR SADDLE
Test that you have the right height by sitting on the saddle with
your heel on the lower pedal and your leg slightly bent. If your
leg is bent more than slightly, your seat should be adjusted up.
If you can’t reach the pedal, your seat should be adjusted
down. To avoid damage to the seat post or eBike frame, do not
position the saddle beyond the minimum insertion line on the
seat post. If you can’t properly position your saddle, see your
bike shop.
GET TO KNOW YOUR EBIKE

14
WARNING: A wheel attachment device, including a quick-release, not correctly adjusted and
closed can move independently and catch in spokes or a brake rotor. In addition, the wheel may
become loose or come off, suddenly stop the wheel, decrease your control, and cause you to
fall. Make sure your wheel is correctly installed and rmly attached before you ride your eBike.
CHECK THE WHEELS
1. Check rims and spokes for damage. Give the wheel a spin. It should spin straight through
the fork (front) and chainstays (rear).
2. Check that the axles are fully seated in the dropouts.
3. Lift your eBike and hit the top of the tire with a solid blow. The wheel should not come off,
be loose, or move from side to side.
4. If your wheel is equipped with a quick-release, make sure the lever is properly closed and
positioned (in-line with the chain stay or front fork) and does not interfere with the spokes
or disc brake system as the wheel rotates.
WARNING: Securely clamping the wheel with a quick release system takes considerable force.
If the wheel is not properly secured, the wheel can become loose or fall off causing serious
injury. The nut should be tightened enough that you need to wrap your ngers around the fork
to close the lever.
CHECK THE TIRES
Use a tire pump with a gauge to make sure your tires
are inated within the recommended pressure range.
Do not exceed the pressure limit as stated on the side
of the tire or rim; whichever is lowest.
NOTE: It is better to use a hand or foot pump than a
service station pump or electric compressor. The latter
are more likely to allow for over-ination, which can
cause the tire to blow out.

VISIT US AT BAKCOU.COM | 15
CHECK THE BRAKES
1. While standing still, make sure you can apply
full braking force without the brake lever
touching the handlebar. (If the lever touches,
your brakes may need adjustment.)
2. Check that the front wheel brake is working
properly. Ride the eBike at slow speed and
apply the front wheel brake. The eBike should
come to an immediate stop. Repeat the
process with the rear wheel brake.
WARNING: Brake force applied to the front wheel
suddenly or too fully could lift the rear wheel off
the ground. This could decrease your control
and cause you to fall. For best results, apply both
brakes at the same time.
CHECK THE CHAIN
1. Make sure your chain has the correct tension
so that it can’t fall off. If you’re unsure of the
correct tension, see your bike shop.
2. Check that the chain has no kinks, rust, broken
pins, plates, or rollers.
CHECK THE CABLES
Make sure all cables and housings are properly
secured to the frame or fork so that they cannot
interfere with or get caught on moving parts.
CHECK REFLECTORS, LIGHTS, & ACCESSORIES
1. Make sure your reectors, lights and any
other accessories are securely attached,
properly positioned, and working properly.
2. Position your lights parallel to the ground.
Make sure your batteries are charged.
CHECK YOUR BATTERY AND CONTROLLER
Check that your battery is locked in the dock and
fully charged, and your controller and eBike system
are functioning properly.
CHECK YOUR SUSPENSION
Adjust your suspension for your use, and make
sure that no suspension component can “bottom
out” or be fully compressed.
CHECK YOUR PEDALS
1. Make sure your pedals and shoes are clean and
free of debris that could affect your grip or
interfere with the pedal system.
2. Grab your pedals and crank arm and wiggle to
see if there’s any looseness. Also spin the
pedals to make sure they rotate freely.

SAFETY PRECAUTIONS
Follow these essential safety precautions to reduce your risk of harm when riding your eBike.
GEAR UP
1. Always wear a helmet when riding your eBike to reduce the risk of head injury in an accident.
2. Make sure your helmet ts you properly and meets the required safety standards.
3. Dress appropriately. Loose clothing or accessories can get caught in your wheels or other
moving parts and cause you to fall (e.g. pants leg in the chainring).
4. Make sure all loose straps & accessories are secured (backpack, tie-down, bungee cord, panniers, etc).
5. On an eBike, the unique up and down pedaling motion is what makes you recognizable on the road.
At night, highlight your feet, ankles, and legs with products that feature reective material.
6. When on the road use front and rear lights, day and night.
7. Make sure your reectors are clean and properly positioned.
WARNING: Reectors, which function only when light shines on them, are not a substitute for lights.
Riding in dark conditions or at times of poor visibility without adequate lighting is extremely hazardous.
RIDE SMART
1. Know your skill level and do not ride above it.
2. Do not ride distracted. Using a mobile phone, music player, or other devices while riding can lead
to an accident.
3. Do not ride too fast. Higher speed creates higher risk, and results in higher forces if a crash occurs
(you may be surprised at the power of your Bakcou eBike).
4. Do not ride hands-free. Always keep at least one hand on the handlebar.
5. Do not ride while intoxicated or while using medications that can make you drowsy or less attentive.
6. Always obey all laws, rules and/or regulations regarding the use of electric assisted bicycles.

VISIT US AT BAKCOU.COM | 17
KEEP IT CLEAN
Clean your eBike with water or mild detergent and a non-abrasive sponge if your eBike is very dirty. Never
spray your eBike using high pressure, and never spray directly onto bearing points or electrical parts.
Never use harsh chemicals or alcohol wipes to clean your eBike.
PART REPLACEMENT
If you need to replace any eBike parts (worn brake pads, for example, or broken parts from an accident),
visit your bike shop or the Accessories page of www.bakcou.com. Use only genuine replacement parts. If
you use anything other than genuine replacement parts you may compromise the safety or performance
of your eBike.
Your safety depends on the correct maintenance of your eBike. After any repair or accessory installation,
check your eBike as shown in the Before Every Ride section on page 13 of this manual.
PARKING, STORING, AND TRANSPORTING YOUR EBIKE
Prevent theft! Do not park your eBike unless you secure it to a xed object with a bike lock that resists bolt
cutters and saws. Lock the battery in place and remove the controller, if necessary. When using a bike rack
ensure that the rack is rated to carry the increased weight of an eBike.
MAINTENANCE
Technological advances have made eBikes and eBike parts more complex, and the pace of innovation is
increasing. It’s impossible for this manual to provide all the information required to properly repair and/or
maintain every eBike. To help minimize the chances of an accident and possible injury, it’s critical that
you have your bike shop perform any repair or maintenance not specically described in this manual.
Many variables, from your riding style to geographic location, will determine your maintenance
requirements. The longer you neglect maintenance, the more it becomes critical. Your bike shop can
help you decide your maintenance requirements. After initial use, new eBikes should be checked.
As an example, cables stretch through use, and this can affect the operation of shifting or braking.
Approximately two months after you purchase your new eBike, have your bike shop fully check it. Have
your bike shop fully service your eBike each year even if you did not ride your eBike much. Before each
ride, perform an inspection as outlined in the Before Every Ride section. If a part malfunctions, check
and service it immediately, or consult your bike shop. If a part has wear or damage, replace it before you
ride your eBike again.
SAFEGUARD YOUR EBIKE
Follow these safeguards to keep your eBike in good shape for the long haul.

18
INSPECTION
Perform the following inspections and maintenance when indicated.
CHECK TIGHTNESS
Your new eBike left the shop with bolts and connections properly tightened — but those bolts and
connections loosen over time and sometimes even during shipping. This is normal. It’s important to check
and adjust them to make certain they are tight.
KNOW YOUR TORQUE SPECS
Torque is a measure of the tightness of a screw or bolt. Too much torque can stretch, deform, or break
a bolt (or the part it attaches). Too little torque can allow the part to move and may lead to fatigue and
breakage of the bolt (or the attached part). A torque wrench is the only reliable method of determining
correct tightness. If you do not have a torque wrench, you cannot properly inspect for tightness and
should consult your bike shop. The torque specication is often written on or near the bolt or part. If a
part does not have a specication on it, ask your local bike shop or contact the Bakcou customer service
department. It shouldn’t take more than a few minutes to check the following and adjust as necessary to
proper torque specs:
HANDLEBAR
Check that the handlebar grips are secure (they shouldn’t move or rotate).
WARNING: A handlebar end that is not plugged or covered can cut the rider in a crash. Inspect regularly.
FRAME AND FORK
Examine your frame and fork, especially near junctions, and clamping or attachment areas. Look and feel
for signs of fatigue: dents, cracks, scratches, deformation, discoloration, unusual noises (e.g. chain slap or
brake rub during acceleration). If you nd any, contact your bike shop before riding the eBike.
BRAKES
1. Check the brake pads for wear.
2. On the disc brakes, replace brake pads that are thinner than 1mm.
3. Check the thickness/wear of the rotors.
4. The minimum thickness is often printed on the disc.
