4.8 DAMPING SYSTEM
Damping can keep the tire buffer in contact with the ground when your bike is running on the uneven road so that the driver feels
more comfortable while driving on the uneven road. Damping hardness can be adjusted by changing the damping coeffici t
according to road conditions and personal preference.
Adjustment method of damping (as shown): Rotate toward the "+" direction to increase the damping coeffici t, thus increasing
the damping hardness; rotate toward the "-" direction to reduce the damping coeffici t thus decreasing the damping hardness.
5. USE AND MAINTENANCE
5.1 ROUTINE INSPECTION BEFORE USE
1. Install the battery box in the battery box slot, open the power supply switch and check whether the functions
of all the electrical components are normal.
2. Safety inspection (see the notes on safe use in the manual)
3. Check whether the throttle rotates and works correctly.
4. Check whether the braking power-off fun tion and braking work correctly
(braking distance on dry pavement: 4 m, on wet pavement : 15 m)
5.2 EVERYDAY USE AND INSPECTION
With everyday use of the electric bike, the mechanical and electrical parts can become worn, screws and other fasteners can also
come loose, resulting in electrical components falling off. If these occurrences are not noted, the e-bike can stop working, and your
safety can be put at risk when cycling. Therefore, it is important to carry out routine inspection and maintenance of your e-bike.
5.3 MAINTENANCE
To ensure road safety, every so often, check that all the electrical parts are in working order and whether there are any loose wires and
whether mechanical parts are functioning normally. Clean, wipe, oil the chain, flu ed disc, fl wheel and derailleur regularly (consult
your supplier for the type of oil product to use). This will ensure that all parts are functioning normally.
6. RIDING SKILLS
Correct cycling posture is essential for safe riding. The riding posture is closely related to the height and size of the cyclist. Proper
cycling posture not only determines the efficie y of muscle movement, but at the same time determines whether the cyclist can
manipulate the handles and brakes safely.
Safety riding skills: Adjust three parts of the e-bike to suit your body; bicycling is just like buying clothes—you need take
measurements and make adjustments. The method of adjusting three parts is a combination of bicycle sports mechanics,
exercise physiology and safe riding.
1. Adjust the position of the seat: Use your heel to push the pedal down and let the muscles in your legs to contract
without forcing them. The legs should be able to bend very slightly.
2. Adjust the height of the handlebar: For the height of the bar, in general, the riser bar is about 30-50 mm higher than the seat,
and the fl t bar is the same high as the seat. The top of the lower curve is the same height as the seat.
After adjusting, pay attention to the direction of the handlebar and then lock.
*Sitting posture on the seat: Similar to the posture on horseback, weight is placed on the handle and pedals and not on the upper
body, to prevent hip pain.
*Pedal position: The top third of your foot should be positioned on the middle of the pedal. Your feet must be parallel with the
center line of the bike to ensure optimal efficie y. You should try to pedal at a uniform speed to avoid fatigue.
*Slowdown skills: The speed change gear is used to slow down but not to accelerate. It stabilizes the number of revolutions of the
pedal, to relieve fatigue arising from uneven force. You should change gears in order to lesson effort and ride more comfortably.
You should change gears when going up a hill; riding on uneven pavement or against the wind; or when feeling tired or uncomfortable.
*Braking skills: As you may be aware, when hard braking you should stop the rear brake then the front brake. But in case of an
emergency, people generally use both brakes at the same time. If the braking distance is adequate, the bike can stop securely; if the
slowdown is too fast, people often would be thrown forward. To prevent this, the best way to stop is through intermittent braking.
On rainy days, increase the braking distance and reduce speed in order to stop safely.
