The Dualtron Thunder II is a personal mobility electric scooter designed and manufactured by Minimotors Co.LTD., a company with a professional production system since 1999. The brand "DUALTRON" is globally recognized for its electric scooters, known for pioneering the world's first dual-drive system and incorporating new rubber suspension technology (patent pending). This luxury Korean brand exports to over 30 countries.
The Dualtron Thunder II is an electric scooter primarily used for personal mobility. It features a dual-drive system, providing powerful acceleration and enhanced performance. The scooter is equipped with an EYE throttle LCD instrument panel, which displays essential information such as battery level, trip distance, odometer, time, speed, and allows for mode changes. The instrument panel also enables various settings, including speed step adjustment, start method (acceleration start or kick start), cruise mode, slow start, battery save mode, electronic brake strength, LCD brightness, auto-off time, and ABS setting.
The scooter's control system includes a main power switch, a POWER button on the instrument panel to turn it on/off, and switch buttons for lights, horn, and driving modes (ECO/Turbo). It also features LED BAR functions, which can be controlled via a remote. These functions include brightness, light speed, number of lamp beads, multicolor light mode selection, and light change mode selection, offering a customizable lighting experience.
Safety features are integrated into the design, such as an electronic brake system with adjustable strength and an Anti-Lock Brake System (ABS) to prevent wheel lock-up during sudden braking, enhancing rider safety. The scooter is designed for a single adult rider, with specific warnings against companion boarding.
To use the Dualtron Thunder II, the user must first unfold it. This involves releasing the QR lever, raising the locking slide, raising the handle post, and then lowering the locking slide. The folding parts are secured by tightening a finishing screw. The handlebar is unfolded by loosening the QR lever, pulling the locking slide inward, raising the handlebar, and then closing the QR lever and tightening the set screw. The handle is locked by placing the locking slide up to the safety line and securing it with the QR lever.
Starting the scooter involves turning on the main power switch and then pressing the POWER button on the instrument panel for two seconds. The instrument panel allows for setting various driving parameters, including start mode, cruise mode, electronic brake, and ABS function.
For stopping, the user should primarily use the rear brake for deceleration, followed by both front and rear brake levers for a smooth and safe stop. The electronic brake can be set for use and strength through the instrument panel, working in conjunction with the brake levers to increase braking force.
The scooter supports a cruise mode for automatic driving, which can be activated by setting the Cruise function on the dashboard and applying the throttle. It is released by holding and releasing the brake.
Charging the scooter involves opening the charging port cap, connecting the charger to the port and a household outlet. The charging status is indicated by an LED (red for charging, green for complete). It's crucial to close the charging port cap when not charging and to use only the genuine charger provided by the manufacturer.
Regular maintenance is crucial for the Dualtron Thunder II's longevity and safety. Before each ride, users should check the throttle and handle for proper return to the home position and ensure the QR lever is fastened correctly. Brake and cable checks are essential, including verifying sufficient braking force, checking for worn pads, loose or damaged cables, and any unusual noises. Tire pressure (45 to 50 psi) and wear should also be inspected, along with ensuring all bolts and nuts on folding and handle parts are tight.
Self-maintenance includes adjusting the brake if braking force decreases due to overheating, oil hose damage, or lever loosening. Tire replacement involves removing calipers, the motor, and then disassembling the wheel to replace the tires, followed by reassembly and tightening. After tire replacement, a test run with appropriate air pressure is recommended. Punctures can be repaired using a patch seal.
The scooter features a variable rubber suspension system (patent pending) that allows for 45-step adjustment. This system can be adjusted by modifying the motor shaft distance (3 steps), arm angle (3 steps), and rubber cartridge replacement (5 steps). Adjustments involve removing the front fender, loosening nuts, and then adjusting the suspension arm components to achieve the desired suspension strength.
The self-diagnosis feature on the dashboard helps identify potential issues, displaying fault types such as system, motor, accelerator, or controller errors. If an error appears, the user should stop using the scooter immediately and take it to a service center.
The manual also provides guidelines for the replacement timing of consumable parts, such as swing arms, hinges, steering tubes, handle stems, locking slides, and batteries, which vary depending on driving habits and environment. External damage inspection is also recommended, especially after heavy driving or exposure to strong sunlight, to check for deformation, cracks, or discoloration.
Proper care for the Lithium-ion battery is emphasized, including using only genuine chargers, charging in well-ventilated, dry places between 0-45°C, and storing at room temperature (10-20°C) with a 70-80% charge level for long periods. Any damage, leakage, or unusual odor from the battery requires immediate discontinuation of use and contact with the service center. Battery disassembly, modification, or repair by unauthorized personnel is strictly prohibited and voids the warranty. Disposal of the lithium battery should be done as industrial waste, ensuring terminals are not short-circuited.
