4.7 SPEED CONTROL SYSTEM
Designed to be used in combination with physical strength, the speed control system takes into account different terrains and high
and low pressure wind conditions. The entire speed control system includes a derailleur, front and back fenders, chain plate, and
flywheel and shift cables. The number of speed change series is the number of fluted discs × the number of flywheel pieces.
For example: three pieces of chain plate × 7 flywheel pieces = 21 speed change series, and so on.
4.7.1 GEAR SHIFTS AND DERAILLEURS
TYPE OF GEAR SHIFT: DIAL TYPE (as shown)
The gear shifts are separately positioned on both handles.
The left controls the front derailleur, the right controls the rear one.
4.7.2 ADJUSTING THE GEAR SHIFTS
The gear shifts control the front derailleur and back derailleur.
If the shift cables are loose or too tight, the speed controller doesn't work properly or the chain falls off, the H, L bolt must be 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't climb to the biggest fluted disc.
L bolt: When the chain is toward the inside fluted disc and the chain falls off, the L bolt is locked.
But if it is too tight, the speed can't decrease. Therefore, you must adjust the H, L bolt to a suitable position.
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 coefficient
according to road conditions and personal preference.
Adjustment method of damping (as shown): Rotate toward the "+" direction to increase
the damping coefficient, thus increasing the damping hardness; rotate toward the "-"
direction to reduce the damping coefficient 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 function 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, fluted disc, flywheel and derailleur regularly
(consult your supplier for the type of oil product to use). This will ensure that all parts are functioning normally.
