ABS function setting guide

All electric motorcycles are subject to sudden braking, causing the wheels to stop spinning. As a result, the slip of tire causes the driver to fall down, which can cause accidents. This product is equipped with ABS brake function to hold the tire lock, enabling more secure braking.

  1. ABS function ON
    Set the ABS function part Pd of the dashboard to 1.DUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-36
  2. ABS function OFF
    Set the ABS function part Pd of the dashboard to 0.
    * Pd – When the ABS function is ON, the PA -electronic brake function is canceled.
    ABS brake is an abbreviation of Anti-Lock Brake System. It uses the principle that maximum static friction force is larger than kinetic friction, so that braking distance (distance from breaking to stopping) is shorter than that of normal brake. It has the advantage that the vehicle does not slip well when wheel is rotating.andit is a brake assist system that can stop more safely without wheel lock and slip.

    • Check throttle and handleDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-44
      • Operate the accelerator throttle lever about 2 ~ 3 times to check whether it returns to the home position.
      • Be careful that excessive throttle leaning and manipulation of the throttle can cause malfunction due to internal parts damage.
      • Check the fastening condition and clearance of the QR lever on the handle.
    • Check brake and cableDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-45
      • The brake braking force is sufficient to check the operating condition. If the braking force is significantly lowered, use it immediately after inspection and action.
      • Check that the brake pad is not worn, that the cable is not loose, that the cable is not damaged, or that there is no leakage in the case of hydraulic brakes.
      • If there is an unusual feeling or noise during operation, check for breakage, wear, and deformation of the inner wire of the brake cable.
      • Check that the bolts and nuts of the brake fixing parts are not loose and that the disc is not deformed or damaged.
    • Check tire pressure and uniaxial conditionDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-46
      • Check the front and rear tires for wear and punctures and check the proper air pressure (45 to 50 psi) for the tire. When the shortage of air is shortened, the possibility of puncture increases, so check always.
      • It is necessary to judge the replacement time by observing the appearance of the tire such as tire damage, and uneven wear.
    • Tightening check such as folding part and handle partDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-47
      • Make sure that the bolts and nuts of all parts of the product are tight and free from loosening. Check the fastening condition and clearance of the folding and fixing parts of the handle (QR lever, fixed slide, hinge center bolt, headset nut, swing arm, etc.)

* If there is a folding clearance,
If there is a folding clearance, it can be adjusted with a tongue bolt. However, if you pull it too hard, it will become stiff without a gap, but it may sound ‘crackling’. In this case, if you adjust the tune bolt properly, the noise disappears and the clearance is also adjusted.
* In this case, stop driving immediately.
If you encounter any of the following situations while driving, stop driving immediately and contact your nearest branch or service center for proper measures. If you provide pictures and videos to get accurate diagnosis, professional counseling is available.

  • Unusual heating of the motor

Important noticeDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-52

* Metal vibration may occur due to motor vibration, vibration of the brake disc and pad during the load section that accelerates during driving. (About 15 ~ 30Km, different for each product)
This is a phenomenon in which all revolutions (fans, automobiles, ships, etc.) are vibrating at a specific rotational frequency (rpm) rather than the product. However, if the continuous noise or metal noise is large, there is a possibility that the disk is bent and deformed.
* Please note that after running, there is a risk of burns due to the heat on the motor and brake (especially disk rotor) side.
* Be careful that the bolts of the motor, rim and motor shaft due to the ABS function may be loosened.

Maintenance by self-maintenance
  1. Brake adjustment methodDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-53If the braking force decreases due to overheating of the oil, damage of the oil hose, loosening of the brake lever, oil leakage, etc. after using the brake for a long time on the downhill road, stop using and use after checking it.

(Patent pending)
Causes and countermeasures of disc brake noiseDUALTRON-THUNDER-04-Personal-Mobility-Electric-Scooter-526

The disc braking method uses a disc brake method with many electric kickboards because braking power is good. However, if you get a sharp hissing sound when you hold the disc brake, dust or sand particles on the ground will spill out on the surface of the disc, causing foreign substances to be on the brake pads or disc surface, or bending due to heat or external impact. At this time, clean the inner surface of the disc by turning the wheels with a clean, dry cloth, or straightening the bent discs.
If the above measures are not taken, please visit the nearest branch and take a safety check. There may be another problem.
