Battery and Service Safety
Remove the battery before attempting to service, make adjustments, or perform any
maintenance on your eBike. Removing the battery will help ensure that the motor does
not start inadvertently while service or maintenance is being performed.
The battery should be removed anytime the eBike is stored or left unattended to prevent
unauthorized use or accidental engagement of the motor. Keep the battery out of reach of
children. Failure to remove the battery may result in severe injury or death.
Never use a battery that is cracked or broken. Battery acid is highly corrosive and can
cause severe burns! Battery acid can burn you if it makes contact with your eyes or
skin. It can also damage personal property.
Brakes and Stopping Power
Ensure that the brakes and their system components are free from damage, properly secured, and
working correctly. When fully squeezed, both front and rear brake levers should not be touching
the handlebar. Take your bike to a certified, reputable bike mechanic to have the brakes repaired
if you find a problem.
10

Improper use of the braking system, including over-use of the front brake, can cause
you to lose control and fall. Avoid improper braking by understanding and practicing
the proper application of your brakes as explained in this manual.
Fission Cycles™ bikes come equipped with disc brakes. These brakes are different from other
general types of brakes associated with bikes. Most bikes typically use rim brakes which operate
by squeezing the wheel rim between two brake pads. Disc brakes squeeze a hub-mounted disk
between two pads. Stopping power on your bike can vary depending on adjustments and pad
thickness and wear. Consult your local bike shop about brake options and adjustments based on
your specific needs.
Front and rear brake levers contain safety power cutoff switches, which disable the hub
motor’s assistance when applied. Both levers should be checked for correct operation
before each ride. If the brake lever cutoff switches are not working, please contact
Fission Cycles™ Support.
Brake Reach
Some bikes have adjustable brake levers. These can be adjusted to fit each rider’s specific needs.
For example, if you have a short reach you may need the levers adjusted closer to the handlebar.
This adjustment or brake lever replacement should be done by a certified bike technician or bike
shop.
Disc brakes and discs get very hot during use and could burn skin. Also, the disc edges
may be sharp and could cut skin. Avoid touching the disc or disc brake when hot, or
when rotating.
Disc brakes may have sharp edges that could cut you. Also, after extended use, your
disc brakes may get extremely hot, take special care not to touch them until they have
cooled.
Additional Brake Warnings
Disc brakes have varying amounts of stopping power depending on adjustments and pad
conditions. Use extreme caution when applying the brakes. Never apply the brakes too hard or
too quickly which could cause you to lose control and fall. The excessive or sudden application
of the front brake could pitch the rider over the handlebars which may result in severe injury or
death.
Never ride with worn brake pads or improperly adjusted brakes.
11

Throttle on Demand
With throttle on-demand, you can throttle the bike from a complete stop. This feature is to help
give you that extra push when you need it on a steep hill when arresting at multiple stop signs,
etc. However, we strongly recommend pedaling first and throttling second to ensure proper
stability and preparedness.
Handlebar Stem and Front Wheel Alignment
Make sure the front wheel and handlebar stem are aligned in the proper orientation of each other.
Turn the handlebar from side to side with the front wheel locked between your knees to test the
stem connection of the fork. If any movement is noted do not ride the bike until this is corrected.
Inspect cable routing to be sure the handlebars can turn freely without binding or pinching the
cables.
Check to be sure that your handgrips on the handlebars are in good condition and the bars are not
protruding through the grip.
Suspension, Handlebar, Grips, and Seat Adjustments
The suspension fork on your ebike will affect the handling of the bike so you must understand
how it works before use. The suspension fork should be properly adjusted according to your
weight and terrain. Ensure the handlebar and handlebar stem are properly aligned, fitted to the
user, and secured to their recommended torque values. Handlebar grips should not move easily
on the handlebar end. Loose, worn, or damaged handlebar grips should be replaced before you
ride. The seat and seat post should be properly aligned, fitted to the user, and the seat post quick
release should be properly tightened, fully closed, and secured before riding.
The seat should be adjusted for proper fit and is an important factor in riding safely.
Place pedals at 6 o’clock and 12 o’clock positions. Your bottom leg should be very slightly bent
when the ball of your foot is placed on the lower pedal. If your leg is bent too much you need to
raise the saddle. If you have to rock your hips to reach or can’t easily reach, you must lower the
saddle. Ensure that the saddle is straight and level.
12

Check that the seat is securely mounted on the seat post by lifting and pushing down on the seat.
This should not tilt or move. Next, check the security of the seat post in the frame by attempting
to rotate the seat. If the seat rotates, then the seat tube is not properly clamped into the frame.
Tires and Wheels
Check the tire inflation. Use a tire pressure gauge to check the tire pressure. The tires should be
set between the factory’s recommendation that is printed on the tire.
Check before you ride:
●Spin each wheel and check that the tires are in good shape with no cuts or abrasions. If
these are found, replace the tire immediately.
●Inspect the rim for trueness by spinning it and watching for any side-to-side or
up-and-down wobble. If any movement is noted do not ride this bike until the rim is
repaired.
Wheel Retention System:
Some bike wheels are designed with quick-release attachments and others are bolted directly on
using a hex-nut. There are 3 main methods of attachment as listed below:
· A hollow axle with a “skewer” shaft running through it which has a nut on one end and an
over-the-center cam on the other end.
· A hollow axle with a “skewer” shaft running through it which has a nut on one end and a
hex-key or tightening device on the other end.
Hex nuts or Hex key bolts are threaded into or on the hub axle
A wheel attachment device that is not properly adjusted and closed may allow the
wheel to be loose or come off unexpectedly, causing you to lose control and fall
causing severe injury or death! Make sure the wheels are properly attached before
riding the bike
Your wheels should always spin straight and must be repaired or replaced if they wobble side to
side or up and down when spinning. If your wheels become untrue or spokes loosen, which can
happen with normal use, we recommend that a certified, reputable bike mechanic performs
all-wheel tuning and truing operations on your Fission Cycles™ Bike. Do not attempt to true
wheels or tighten spokes unless you have adequate knowledge, tools, and experience. Ensure the
tires and inner tubes are in good working condition without any visual damage and have the
13

correct amount of air pressure. Always replace tires and inner tubes with punctures, cuts, or
damage before you ride. Tires without the correct amount of air pressure can reduce
performance, increase tire and component wear, and make riding your bike unsafe.
Fork and Frame
Check the frame, fork, and components. If you notice that the frame or fork has any visible
damage, cracks, dents, or you hear any unusual noise while riding or other problems, do not ride
your bike. If at any time you notice a shimmy or wobble, immediately slow down and take your
bike to your local bike shop for inspection and/or repair. Carefully inspect your bike before and
after each ride.
Certain types of riding significantly increase stresses and abnormal wear and tear on
your bike. This can include competition or stunt riding, downhill racing/riding, or
jumping your bike.
Certain types of impacts can affect the components of your bike and cause them to fail
unexpectedly. After any impact or crash, thoroughly inspect all the parts of your bike for
damage. A crash or other impact can put extraordinary stress on the bike. An impact or high
force is any situation such as hitting a hole or obstacle in the road, such as a bump or curb.
An eBike is a mechanical device. Materials and mechanisms are subject to fatigue and
stress. Over time, components can fail once they have exceeded their useful limits and
life. Product life is often related to the kind of treatment and riding you submit your
bike to. Hard and aggressive riding along with neglect will shorten the projected
lifespan of your bike and its components. If not properly maintained, your bike and its
components can fail to cause severe injury or death.
A shimmy or steering wobble can cause you to lose control and fall. If you experience a
shimmy, slow down immediately. Take your bicycle to a certified, reputable bike
mechanic for inspection and repair.
Helmets
When riding a bike, always wear a properly fitted helmet that covers the forehead. Many
locations require specific safety devices. It is your responsibility to familiarize yourself with the
local laws, rules, and regulations where you ride and to comply with all applicable laws,
including equipping yourself and your bike as the law requires.
14

General Warnings

bike, you assume the responsibility for that risk, so you need to know, and practice the rules of
safe and responsible riding and the proper use and maintenance of this bike. Proper use and
maintenance of your bike reduces the risk of damage, injury, and death.
Biking and controlled substances do not mix. Never operate a bike while under the influence of
alcohol, drugs, or any substance or condition that could impair motor functions, judgment, or the
ability to safely operate a bike or other vehicles.
The FM 750x is designed for use by persons 18 years old and older. Riders must have the
physical condition, reaction time, and mental capability to ride safely and manage traffic, road
conditions, and sudden situations, as well as respect the laws governing electric bike use where

Assembly
The following steps are only a general guide to assist in the assembly of your ebike and are not a
complete or comprehensive manual of all aspects of assembly, maintenance, and repair. Consult
a certified, reputable bike mechanic to assist with the assembly, repair, and maintenance of your
ebike.
Step 1: Unpack the bike.
Open the bike box. With the help of another person remove the ebike from the bike
box.Carefully remove the packaging material protecting the bike frame and components. Locate
and remove the smaller boxes. These smaller boxes contain your charger and accessories. Please
recycle packaging materials especially cardboard and foam whenever possible.
Do NOT install the battery until the bike has been completely assembled.
Step 2: Preparing the stem.
Remove the stem rubber cover, loosen the bolt using a 5mm hex key, and discard the packing
protective material.
Loosen the screw in the stem and turn the stem so that it is oriented in the correct direction
and aligns with the front fork.
Step 3: Handlebar Installation.
Loosen and remove the four hex bolts from the mounting bracket cap located on the stem.
Remove and set aside the cap from the mounting bracket along with the four hex bolts. Locate
the handlebars, they will be attached to the frame by several cables.
18

Orientate the handlebars so that the cables are not twisted and adjust the position.
Set the handlebars into the mounting bracket and reattach the cap with the four hex bolts.
Make any final adjustments and alignments then tighten the hex bolts so that the handlebars
are secure. Check all the cables to ensure that they have not lost connection during the
assembly.
Cables can work loose and disconnect during shipping. Check all the cables to
ensure they have not come loose. If a cable is loose, apply gentle pressure to each
19

side to reconnect. If cables are completely disconnected, use the arrows on the side of the
connector to align the pins before connecting. DAMAGE TO THE PINS CAUSED BY
MISALIGNMENT WILL VOID THE WARRANTY
Step 4: Front-wheel installation.
1) Locate the front wheel and remove the black protective guards.
2) Remove fork protective cover and all other plastic protective inserts.
3) Loosen the front axle nuts and slide the front wheel into the front dropout on the fork.
Ensure the brake rotor is between the brake pads of the brake caliper.
4) Use 15 mm open wrench to tighten the front axle nut, recommended torque at 25 - 30
Nm.
A critical aspect of assembling your bike is securing the front wheel and checking
the tightness of the rear wheel axle nuts. Fission Cycles™ bikes use bolted on,
through axle, or quick release front wheel mounting mechanism, and the rear wheel
is bolted on. These mechanisms may become loose or unsecured during shipment or
over time. The torque and security of the mounting hardware should be inspected upon
arrival and on a regular basis. Both wheels need to be properly secured before operating
your bike.
Never touch the brake rotor, especially when the wheel and/or bike is in motion, or
severe injury could occur. Hand oils can cause squeaking and decrease brake
performance.
An improperly secured front wheel and/or handlebar stem can cause loss of control,
accidents, severe injury, or death. Check that the front wheel and handlebar stem are
properly secured to the bike during assembly and before each ride.
