Below is a comprehensive guide for evaluating the quality of elderly mobility scooters, covering core dimensions such as safety performance, configuration quality, and compliance:

1. Safety Performance Evaluation

Vehicle Body Structure

Prioritize metal monocoque stamped bodies or high-carbon steel frames, with welds that are uniform, full, and free of cracks

Paint quality ranking: Pearl paint > Metallic paint > Standard paint. A solid sound when tapping the body indicates proper paint thickness

Braking System

Standard dual disc brakes or front disc/rear drum brakes are required. Electromagnetic brakes (instant stop when released) are mandatory

Braking distance test: Should be ≤5 meters when braking at 25km/h

2. Core Configuration Quality

Power System

Prefer brand-name brushless DC motors, recommended power range 1000-3000W

Controllers should use sine wave (superior to square wave) for smoother operation

Battery Performance

Lithium batteries preferred (LiFePO4 with 2000+ cycles). Lead-acid batteries must have ≥60Ah capacity

Test capacity degradation at full charge - normal rate should be ≤15%/year

3. Detail Quality Inspection

Wheels & Suspension

Brand-name pneumatic tires outperform standard inner tube types. Higher hardness indicates better wear resistance

Hydraulic suspension + pneumatic tire combination improves shock absorption

Function Testing

Check steering accuracy and brake alignment during test rides

All instrument panel indicator lights should function properly with smooth control system operation

Recommend on-site test rides with professional tools (e.g., battery testers), focusing on brake responsiveness, seat comfort, and operational stability.
