RIDING TECHNOLOGY
1 The correct riding posture
：
Body: Back and arms slightly bent, the waist keeps straight;
Hands: The hand with the shoulder width and can not see from behind;
Saddle Height: Sitting on the saddle, Legs straight, heels is stepped on the pedal；
Legs: Keep straight and parallel, not inward or outward；
Feet: Pedaling with front feet.
2 Should pay attention to when riding
：
a Different speed shall cooperate with the different gear, same as the car, starting should use chain wheel.
b Emergency brake：The principle of the emergency brake is brake the front one after the rear one. But in an
emergency, shall work together. If the braking distance appropriately, it is safety to break. If the speed is too
fast, people often will be thrown forward. To avoid this risk, the best method is intermittent brake, while the
hips move back. Particularly, much more is on the rainy day or small stone road.
c Control Speed: In the downhill, especially to turn on the occasion, to prevent career off the road or fall, you
must control the brake.
d Climbing technique: When sloping, besides electric power, pedal assistant is also need. When feel hard, the
solution is:
(1) Switching the speed, you could make the flywheel toward the larger one when you feel comfortable.
(2) Using the upper body strength: waist slightly back, hold the handle to the chest and pedal, so you can
naturally applied to the upper body muscles, reducing the hardship. Do not let the waist leave the saddle, if so,
it is easy to fatigue. At the same time on the slope, it is best to use the two suction breathing methods to
increase oxygen intake.
3 Safety using instructions
：
a. When riding, please obey the traffic rules, to avoid danger.
b When on high speed or downhill, do not use the front brake, in order to prevent the center of gravity
forward.
c The bike for single riding, to prevent the center deviation, please avoid carrying people or carrying more
than 25 kg of goods.
d Please keep the proper air pressure on tire, so as to avoid increase resistance, easy wear of tire and out of
shape when riding.

：
This bicycle only provide rear transmission system, the control part is shifting system on the right of handle.
a When switching to increase the flywheel tooth, please shifting gradually.
B When switching to decrease the flywheel tooth, please press the back button gradually.
2 The instruction of transmission system.
：
a Internal transmission, should choose the sliding speed; the outer transmission should be changed the
speed when pedaling, otherwise the transmission damage easily. Do not astern pedaling, to prevent the chain
drop down.
b Don't change the gear wheel sharply, you should adapt to the changes of terrain, in order to avoid foot
and leg fatigue.
c Uphill before about 60 meters, depending on size the slope, you should switch the transmission. People
often switch the transmission when they can't get up the uphill, not only affect the speed, sometimes improper
operation will also lead to fall, and wearing the machine parts.
d When resting for a long time, please switch the chain to the minimum freewheel tooth, to prevent the
fatigue of machine parts.
e Please do not switch any device of the transmission system when not using.
f Chain, gear, flywheel, transmission, should always clean, wipe the oil with the principle of less oil and

required fit, and then lock the quick release fastener ②.
2): Handlebar Adjustment
See in reference illustration A:
Insertion depth of the stem cannot be less than the minimum depth, to make sure that the safety line
on the stem is adjusted to be hidden.
Attention: During the adjustment of the handlebar stem up or down, please do not disconnect any plug
or electrical parts.
