Modern powerful models such as , are complex engineering solutions designed for speeds of 100+ km/h and off-road. They are equipped with motorcycle-grade components.

Let's analyze the design and rate the complexity of the repair on a scale from 1⭐ (very easy) to 5⭐⭐⭐⭐⭐ (for professionals only).

1. Electrical System: Heart, Brain, and Muscles

A. Battery (Battery, AKB)

• Purpose: "Fuel tank". High-quality cells are used (Samsung/LG 21700). Can be built-in (GTR MAX) or removable (GTR 35Ah).
• Consumable: Yes (has a limited cycle life).
• Repair/Replacement: Caution! Only by specialists due to high voltage (72V) and risk of fire.
• Repair difficulty: ⭐⭐⭐⭐⭐ (5/5)

B. Controller (Power Board)

• Purpose: "Brain". The GTR uses an integrated dual-channel sine wave controller (Kaabo 72V 100A, peak 160A), which ensures smooth running and high efficiency.
• Configuration: Power and acceleration settings are available via the display.
• Repair/Replacement: Requires access to the inside of the deck.
• Repair difficulty: ⭐⭐⭐⭐ (4/5)

C. Motor-wheel (Engine)

• Purpose: "Muscles". All-wheel drive (2 x 2000W).
• Possible problems: Bearing wear, Hall sensors failure.
• Repair/Replacement: Requires special tools.
• Repair difficulty: ⭐⭐⭐⭐ (4/5)

2. Chassis and Mechanics: Skeleton and Joints

A. Frame and Deck

• Purpose: "Skeleton". High-quality models use durable aluminum alloys (6061, 6082, 6063). Protection against moisture (IPX5).
• Repair/Replacement: Difficult, often requires frame replacement.
• Repair difficulty: ⭐⭐⭐⭐⭐ (5/5)

B. Suspension (Damping) – Motorcycle Level

• Purpose: Comfort and traction. The GTR features a motorcycle-style double wishbone front suspension and a hydraulic shock absorber at the rear.
• Configuration: It is critical that the suspension is fully adjustable (front and rear). You can adjust the stiffness and rebound speed to suit the rider's weight and surface type.
• Repair/Replacement: Basic maintenance (cleaning, adjustment) is simple. Hydraulics overhaul is complex.
• Repair difficulty: ⭐⭐ (2/5) for maintenance; ⭐⭐⭐⭐ (4/5) for repair.

C. Brake System

• Purpose: Safety. Only hydraulic disc brakes (160mm disc) are used. The MAX model is additionally equipped with reinforced 4-piston calipers. It is supplemented with an electronic brake (EABS).
• Consumables: Yes (pads, discs).
• Repair/Replacement: Replacing pads is easy. Bleeding the hydraulics requires tools.
• Repair difficulty: ⭐ (1/5) for pads; ⭐⭐⭐ (3/5) for hydraulics.

D. Wheels and Tires

• Purpose: Traction. The GTR uses large 12-inch CST tubeless (vacuum) tires with "run stability control" technology (usually this means increased puncture resistance or the presence of an internal sealant).
• Consumables: Yes (tires).
• Repair difficulty: ⭐⭐⭐ (3/5).

E. Folding Mechanism and Steering Rack

• Purpose: Compactness and control.
• Possible problems: The appearance of backlash is very dangerous! Requires regular monitoring.
• Repair difficulty: ⭐ (1/5) for adjustment; ⭐⭐⭐ (3/5) for bearing replacement.

3. Electronics Control and Safety

A. Throttle Trigger and Display

• Purpose: Control and information. Modern models use bright TFT displays with a high level of moisture protection (IPX7 in GTR).
• Repair/Replacement: Modular replacement (plug-and-play).
• Repair difficulty: ⭐⭐ (2/5)

B. Light and Signal

• Purpose: Safety. Equipped with bright LED headlights, turn signals, deck lighting, and a loud motorcycle-grade horn.
• Repair difficulty: ⭐⭐ (2/5)

C. Advanced Systems (ABS, ESP/Traction Control, Damper)

• Purpose: Electronic aids. ABS (often via EABS) prevents wheel lock. ESP (traction control) prevents skidding. Steering damper (hydraulic stabilizer) – a critical tuning for powerful scooters, prevents "wobble" at high speed.
• Repair/Replacement: Diagnostics is complicated, requires service.
• Repair difficulty: ⭐⭐⭐⭐ (4/5)

4. Consumables: Planning and Purchasing

These parts wear out and need regular replacement.

1. Brake pads: Wear out the fastest (every 500-1500 km).
2. Tires: Wear out after 2000-5000 km. Have a tubeless tire repair kit (harnesses).
