steep slope, use the Pedal to assist as far as
possible to reduce the starting current and
extend the battery life and continuation line
mileage.
c. On rainy days, please pay special attention
to: when the water depth is more than the wheel
center, it is likely for the motor to soak
water, thus resulting in failure.
d. Users must use the charger specified by the
manufacturer for charging the storage battery.
When charging, put the battery and charger
smoothly.
e. It is prohibited that other items are covered
on the battery box and charger to impede heat,
where a good ventilation environment should be

4.1. Introduction to speed boosting system
The speed boosting system is also known as 1:1
boosting system. And the so-called 1:1 automatic
power assisting is that when you ride only by
means of feet, the sensor with you bike will
automatically sense your riding speed and control
the motor to assist you automatically in a
driving force with the same speed, so as to let
your ride easier and make the continuation line
mileage further.
1:1 boosting system comprises a controller,
sensor and induced cartridge.

4.2. Charging
Ezriderz - copyright 2022
As it will last a certain period of time for the
ex-factory, transport and storage of a just
purchased new bike, it is likely to result in
shortage of the battery power, the battery should
be first charged before it is used.
The charger configured or designated by eRider
Cycles must be used for charging otherwise it
might damage the battery, and may even lead to
fire and other danger.
4.2.1. Installation and charging of battery（as
shown in Figure 1 and Figure 2）

4.2.2. Charging steps and method
1. Check carefully whether the rated input
voltage of the charger is consistent with the
voltage of the power grid.
2. The battery can be directly put on the bike
for charging and can also be taken down from the
bike to be charged indoors and at other
appropriate places.
3. Connect first the output plug of the charger
with the charging jack of the battery properly,
and then connect the input plug of the charger
to the AC power supply.
4. At this time, the power indicator light and
the charge indicator light of the charger are
on, indicating that the charging has been
connected.
5. After charging, should first pull out the AC
Ezriderz - copyright 2022
power plug, and then pull out the plug connected
with the battery.
After the battery is fully discharged, the
one-time charging time is 6 to 8 hours, and
after the charge indicator light is red from
green, the power capacity of the battery has
been basically sufficient.
Ezriderz - copyright 2022
Common sense of charging and use:
* The battery should be charged in a spacious
environment, staying away from high temperature,
high humidity and close fire. Because the
battery and the charger are electronic products,
high temperature and humidity will corrode
electronic components, resulting in some harmful
gasses and soot, and even a possible explosion to
wound.
* The charging time should not be too long. A
long charging will lead to shortened life
expectancy of the battery.
* After the battery is fully charged, the power
supply should be pulled out as soon as possible,
and at the same time, the battery is taken out
of the charger.
* When the battery is not used for a long term,
the battery power should be emptied before the
battery is preserved, and must be re-charged once
every month or so.

4.4.1 Position of
Vertical handle stems
The Vertical handle stems can be appropriately
adjusted depending on personal preferred riding
perspective, butthe insertion mark (that is, the
safety line)can not be exposed; in case of
improper use,it may cause serious injury to the
riders.
1 Loosen the handle core screw rod;
2 Move the Vertical handle stems to the
appropriate height, and pay attention to not
exceeding the safety mark (that is, the safety
line);
3 Fasten the core screw rod;

4.5 Braking system
The braking system is an accessory necessary for
each bike and is the key to traffic safety;
before driving, you must understand your braking
system, and do a good job in the inspection and
adjustment work.
The general idea is that upon hard braking, the
bike will surely stop in a short distance, but
that is wrong. Upon hard braking, when the
wheels are suddenly jammed by the brake rubber,
the bike will glide horizontally, and it is not
only dangerous, but the braking distance will be
lengthened. Therefore, the concept should be
established that the braking system is only used
to adjust the speed of the bike.
The braking system typically includes a Brake
handle, brake (disk brake, V brake and many
other types of brakes) and brake cable.
Ezriderz - copyright 2022
4.5.1 Brake handle
The structure of the Brakehandle is as shown (in
the left drawing), and the left Brake handle
controls the front brake and the right Brake
controls the rear brake.
. The adjusting screw is used to adjust the
distance between the brake shoe block and the
Rim.
. The effective stroke of the brake cable is
about a half of the distance between the handle
of the Brake handle and the grip of the Across
handle Stems; if the brake is tight when the
handle of the Brake handle is almost approaching
to the grip of the Across handle Stems, the
distance between the brake shoe block and the Rim
is too large, it needs to be adjusted.

7 Permanent seat of brake line
Adjustment method of the brake shoe block:
1 Loosen the positioning bolt;
2 Adjust the distance of the shoe block through
the left and right knob; when the shoe block
adjusts the left knob of the bolt, the distance
of the brake shoe block is increased, and vice
versa it becomes small (as shown in the disk
chart). Depending on the circumstances, the
braking is adjusted;
4.5.3 Brake cable
．The brake cable of the flat handle
. The bifurcation situation of the internal line
should be avoided, so a tail sleeve had best be
covered on the line end.
. The brake cable should be regularly taken out
to be oiled, to avoid too large resistance
arisen from rust.
. The brake cable in a linear way has the best
Ezriderz - copyright 2022
function, and if it must be bent, the turning
with a small arc should be avoided as far as
possible.
. The length of the brake cable is based on the
principle that it will not be stuck when the
handlebar turns left or right to the limit.
Common sense of the use of braking system：
* When the distance between the brake shoe block
and the Rim is too large, it is adjusted by the
Brake handle or the adjusting screw on the
folder gate device.
* When the lines of the brake shoe block are worn
seriously, replace it timely in order to
maintain traffic safety.
* When not riding for a long time, please loosen
the folder device to avoid fatigue of
flexibility, but pay attention to recovery of the
gate device before riding.
* When riding in rainy days, the function of any
gate device will be weakened, so please keep a
longer safe braking distance and reduce the
speed.
* The surface on the brake disc, shoe block may
not be oiled, so as to avoid serious injury.
* If the brake cable is ripped, it may cause the
brake cable to be broken and this is very
dangerous, please replace it timely.

4.7 Derailleur
Type of Derailleur (as shown)
Ezriderz - copyright 2022
The Derailleur is separately positioned on both sides of the Across
handle Stems, and the left controls the forward speed and the
right controls the backward speed. When the forward speed grip
rotates to the riding direction, big teeth change to small teeth, and
on the contrary small teeth change to big teeth.
When the backward speed grip rotates to the riding direction,
big teeth change to small teeth, and on the contrary small
teeth change to big teeth.

4.7.2 Derailleur
The derailleur is classified into the front
derailleur and Back fender (as shown ).
When the shift cables are loose or too tight, if
the speed controller does not work properly or
the chain falls off, the H, L bolt is adjusted.
H bolt: when the chain speed changes to the
biggest fluted disc, the chain will fall off, and
the H bolt will be locked. But if it is too
tight,the chain can not climb to the biggest
fluted disc.
L bolt: when the chain is toward the inside
fluted disc and the chain
