20 inch foldable strong beach electric fat bike for girls
Before riding an electric bicycle, check the tire pressure, the
steering flexibility of the handlebar, the flexibility of the front
and rear wheels, the circuit, the battery power, the working
condition of the motor, and whether the lighting, horn, and
fasteners meet the requirements for use.
(1) Insufficient tire pressure will increase the friction between
the tire and the road surface, thus shortening the mileage. It will
also reduce the flexibility of the handlebar and affect the ride
comfort and safety. When the air pressure is insufficient, the air
pressure should be replenished in time. The tire air pressure
should be in accordance with the recommended air pressure in the
"Electric Bicycle Instruction Manual" or the specified air pressure
on the surface of the tire.
(2) When the handlebar is inflexible, if it is stuck, stiff or
tight, it should be lubricated or adjusted in time. Lubricating
generally uses butter, calcium-based or lithium-based grease; when
adjusting, first loosen the front fork lock nut, rotate the front
fork upper block, when the handlebar rotation flexibility meets the
requirements, lock the front fork lock nut.
(3) The flexibility of the front and rear wheels is not good, which
will increase the rotational friction and increase the power
consumption, thus reducing the mileage. Therefore, in the event of
failure, lubrication and maintenance should be timely. Lubrication
generally uses butter, calcium-based or lithium-based grease. If it
is a shaft failure, the steel ball or shaft can be replaced. If it
is a motor failure, it should be repaired by a professional
maintenance unit.
(4) When the circuit is inspected, turn on the power switch, check
whether the circuit is unblocked, whether the connector is plugged
firmly and reliably, and whether the fuse is working properly,
especially if the connection between the battery output terminal
and the cable is firm and reliable. The fault should be found out
in time.
(5) Before traveling, check the battery's power and determine
whether the battery is fully charged according to the mileage of
the trip. If the power is not sufficient, it should be supplemented
by human riding to avoid undervoltage operation of the battery.
(6) The working condition of the motor should also be checked
before traveling. Start the motor and adjust its speed to observe
and listen to the motor. If there is any abnormality, it should be
repaired in time.
(7) Before using the electric bicycle, check the lights, speakers,
etc., especially at night. The headlights should be bright, and the
beam should generally fall within 5-10 meters in front of the front
of the car; the horn should be loud and not hoarse; the turn signal
should be flashing normally, the steering indication is normal, and
the flashing frequency of the light is 75-80 times/min; The display
should be normal.
(8) Before the trip, check whether the main fasteners are fastened,
such as the horizontal tube, the riser, the saddle, the saddle
tube, the front wheel, the rear wheel, the middle shaft, the lock
nut, the ankle, etc. It should not be loose. If the fastener is
loose or loose, it should be tightened or replaced in time. The
recommended force distance of each fastener is generally: the
horizontal pipe, the riser pipe, the saddle, the saddle pipe, the
front wheel and the ankle are 18N.m, and the middle axle lock
mother and the rear wheel are 30N.m.
