Please use the pedal assist mode.
Do not brake frequently under the premise of ensuring safety.
Do not overload.
Before riding, please check the tire pressure; the tires shall have enough pressure,
generally between 35PSI-65PSI (280KPA-450KPA).
1. Precautions for users
Avoid exposure to sunlight or rain for a long period, and avoid storing our
electric bicycle at a hot place or a place with corrosive gas to prevent damage to
electroplated parts and painted surfaces.
For the safety of others and avoid bike damage, please do not lend the bike to
someone who cannot ride it.
Frequent braking, driving against the wind, carrying people or objects and
insufficient tire pressure, etc., will consume a lot of power and reduce the endurance
mileage.
To obtain the best endurance mileage, follow the following instructions:
Please keep the two keys properly. You would not be able to start the electric bike or
change the battery if the only key is lost. You shall get more backup keys if necessary
(we do not provide them). Please turn to professional institutions in case of loss and
the user shall bear the whole responsibility.
The electric bicycle is a means of transportation with certain risk factors. Please
be sure to observe the traffic rules. In case of emergencies such as riding too fast,
please brake the rear wheel first and then brake the front wheel. If the front wheel is
suddenly braked, there is a danger of tipping over. Please ride with care.
Do not ride the electric bike on highways.
This electric bike is not suitable for riding on motorway or at any other inappropriate place.
Before riding this electric bike, please carefully check the state of the body. You shall
be responsible for any consequences caused by your improper operation or use.
Your current insurance may not cover the situations that you may encounter while
riding the electric bike, please contact your insurance company or insurance broker
for relevant consultation.
The user shall be solely responsible for the safety problems caused by improper use.

6.6 Adjustment and Use of Brake
Before aligning the mechanical disc brake, make sure that the brake cable is properly
inserted into the brake lever. If the disc rotor is bent or damaged, replace the rotor first.
The brake is used to control the speed, not just to stop the bike. The maximum braking
force of the wheel is available before the wheel "lock" (standstill) and subsequent
slip. Once the tires skid, you will lose most of your braking power and any control of
the bike. You must practice braking and stop gently, without jamming the wheel. This
technique is called progressive brake modulation.
If the brake is not sensitive, loosen the
fixing bolt of the brake cable, shorten the
braking distance of the brake cable, and
then tighten the bolt. Or, when the brake
is too sensitive, increase the distance of
the brake cable.
If the rotor is always rubbing against the
brake pad or has excessive clearance,
loosen the two centering adjustment
screws, but do not remove them. Turn
the wheel slowly and check the space
between the rotor and the brake pad;
adjust the position of the brake pad and
rotor to avoid friction between the the
rotor and pad. After the adjustment,
tighten the screws.
Leave the same clearance on
both sides of the disc rotor

6.6.1 Adjustment of Brake
6.6.1 Adjustment of Brake
Push the brake lever towards the handlebar to gradually increase the braking force.
If you feel the wheels get stuck, reduce the braking force so the wheels can continue
to spin without being stuck.

6.8 Charging: Safe operation guide
For safe and comfortable riding, the distance from the ground to the rider's crotch
shall be 76 cm/30 inches when the rider is standing on the ground. In addition, there
should be at least 3-8 cm/1-3 inches between the crotch and the bike's top tube.

6.9 Instructions for Use of Shift Lever
The shift lever shall be used during riding. When the bike is stationary, do not turn
the shift lever to avoid damaging your bike.
6.9.1 Use of Left Shift Lever
6.9.2 Use of Right Shift Lever
When the left shift lever is shifted forward, the front shift lever will move outward,
and the shift chain will move from the small piece of the fluted disc to the large
piece, which will increase the riding speed and increase the pedaling strength;
When the lever is turned back at the maximum position, the front shift lever will
move from outside to inside, and the shift chain will move from the large piece of
the fluted disc to the small piece at the same time, which will reduce the speed of
riding and the pedaling strength of riding, so as to realize the shifting process of
the front shift lever.
When the right shift lever is shifted forward (the tap position is changed from
position 7 to position 1), the rear shift lever will move inwards, and the shifting
chain will move from the small piece of the rear Cassette to the large piece at the
same time, which will reduce the riding speed while reducing the pedaling strength
of riding;
When the lever is at the maximum position (tap position 1), press the acceleration
button on the right shift lever. The rear shift lever will move from the inside to the
outside, and the shift chain will move from the large piece of the Cassette to the
small piece position, which will increase the speed of riding and will also increase
the pedaling strength of the riding, so as to realize the shifting process of the rear
shift lever.
