Instructions
1. Please read the manual carefully before using your EMOJO electric bic ycle.
2. Make sure all parts are locked tightly, such as the frame joint, handlebar, seat post and pedal, etc. Before using. Do
not use the electric bicycle before carefully reading the instructions and knowing about the performance of the electric bicycle.
Do not lend the electric bicycle to anyone who does not know how to operate it.
3. Develop a habit of charging when the power of the battery pack shows a red light. Please charge and maintain the battery
pack consistently to have longer service; if the bicycle is not to be used for a long period, it is suggested to turn power of the
battery pack to the OFF position and charge-discharge the battery once per month.
4. Frequent braking, starting, uphill, still starting, muddy and uneven ground, overloading of people and goods will assume larger
electricity, thus influencing the travel mileage. If you want to get the best travel mileage, we suggest you follow the following
instructions:
Ride the bicycle to a certain speed by pedaling prior to turning on pedal-assist or throttle power.
Try to decrease the frequency of braking and starting while maintaining safe riding habits.
Please assist with pedal when the slope angle is steep, or the wind speed is fast.
5. When you lift the battery, please do not insert any metal objects (such as wires, keys, etc) into the charging socket or bridge the
negative and positive poles of the battery cell. This can cause battery short-circuit, resulting in a fire and putting your safety at risk.

Hand Throttle Control
Your electric bike is equipped with a power and throttle control on the
right hand side. To power on your bike first make sure to turn on your bike
by pressing and holding the M button on the left side.
You control the throttle by pushing with your thumb the paddle, the farther
you push from its resting position, the more power is delivered to the
motor to accelerate. When you want to slow down, you simply release the
throttle and let it return to its resting position and simultaneously apply the
brakes.
When the pedal assist mode is set to "0", the pedal assist and throttle function(s) do not engage. When the pedal assist mode is set to "5" the
pedal assist function will engage to the maximum speed level and the throttle will accelerate the bike forward. The throttle control is operated
on the right hand side.
When you want to slow down, you simply release the throttle and let it return to its resting position and simultaneously apply the brakes.

Mechanical gears
This EMOJO electric bike is equipped with 7 mechanical gears in addition to the pedal assist levels. The first gear is for eas ier and uphill pedaling,
the last gear is for maximum speed on leveled ground or downhills. Change gears only when pedaling. The rear wheel c ontains seven chain
sprockets. When the chain is around the largest sprocket, you are in the 1st gear which is the "lowest" gear. The high gear wi ll have the dérailleur
positioned so that the chain is directed around the smallest gear selector and cause it to change gear. Adjustments require fine tunning and should
be made by a qualified technician.
Avoid changing gears rapidly from 1st to the 7th gear or vice-versa. If you change multiple gears too quickly, you could have the chain come off the
front sprocket.

Caliper
FFree rotation between
disc and caliper.
Your electric bike is equipped with disc brakes for maximum
reliability. Applying hand pressure to the brake levers will
engage the brake pads against the brake rotor, creating friction
and slowing down the wheel. The more hand pressure applied
to the brake lever, the faster the bike will come to a stop.
Check the front disc handle gap by depressing the brake lever
about 10 times to check that everything is operating correctly
(Fig. 1 ) If necessary you can ad j ust the brake by turning the
dial on cable (shown with a red arrow). Your front wheel must
spin free at all times without any friction from the brake when
not applied.
The rear brake should always be applied before or along with
the front brake. Applying only the front brake to slow or stop at
high speeds may result in the rider being ejected from the
saddle and continuing forward over the handlebars. It is best to
apply even pressure to both brake levers when slowing or
stopping.
Bicycles equipped with disc brakes will occasionally make a
slight scraping noise when the wheels are turning without the
brakes being applied. This is normal.
Make sure that the brake lever does not contact the handlebar
when full hand pressure is applied (b) The contact point should
feel firm and solid. If the lever travels all the way to the
handlebar or feels spongy, they may require service by a
qualified bicycle technician.
If the brakes are still not operating correctly, they may require
further adjustment by an experienced bicycle mechanic.
WARNING:
• Disc brake rotors become hot during use. Do not touch
or come in contact with the disc rotor shortly after use.
• Wet weather will require a longer distance to stop. Brake
earlier and avoid sudden stops when riding in wet
conditions.
New Brakes Bed-in Procedure
New brakes will require a "bed-in" procedure prior to your
first ride which will ensure the most consistent and powerful
braking feel.
Find a safe riding area that will allow for moderate
speed. Remain seated during the entire procedure for optimal
results.
IMPORTANT:The caliper might need to be adjusted and
aligned to ensure there is no constant friction when the brake
is not applied avoiding unpleasant noises, premature wear or
poor braking. If necessary, adjust your calipers by loosening
the sockethead bolts, and gently moving the caliper with your
hand until is centered and aligned with the disc. While holding
with your hand the caliper in the correct position, tighten the
adjustment bolts again.

4. Pedal Installation and Adjustment:
Take out pedals from the accessory box, install one of the pedals (pedals are marked with the letters "L" and "R" to indicate the side they
belong to). When installing the pedals, insert the wrench stuck on the flat end of pedal axial head, and twist into the crank in clockwise direction.
5. Check and Adjustment of Tire Pressure
Keep proper air pressure, the space between tire and ground contact is about 4 inches long when riding on the electric bicycle.
6. Brake Adjustment
A. When brake lever reaches 1/3 of unstressed state, the power will be cut out completely, when it is at 1/2, bike can brake completely.
B. The distance between brake pad of front wheel and rim should not be more than 2mm, when the brake pads wear down, timely adjustment is
possible, after adjustment, the brake pad should not interfere with other spare parts. When a worn brake pad reaches 1/2 of its thickness, it must
be replaced.
