2. Key indicators of maneuverability test
Steering flexibility
Test method: Two methods can be used: in-situ steering test and driving steering test. The in-situ steering test mainly measures the force and steering angle required to turn the steering wheel or handle the vehicle in the in-situ state; the driving steering test is to perform steering operations when the vehicle is driving at different speeds to observe the vehicle’s response speed, steering accuracy and stability. For example, let the vehicle drive at different speeds such as 10km/h and 20km/h, turn the steering wheel to the left and right by a certain angle, and record the vehicle’s steering response and driving trajectory.
Importance: Good steering flexibility can make it easier for the elderly to control the vehicle in narrow streets, parking lots and other places, avoid collisions and scratches, and improve driving safety. At the same time, it can also make the elderly more handy during driving and reduce fatigue and discomfort caused by steering difficulties.
Acceleration and deceleration performance
Test method: The acceleration performance test can be evaluated by measuring the time required for the vehicle to accelerate from a stationary state to a certain speed, such as the time required to accelerate from 0 to 30km/h. The deceleration performance test can be evaluated by measuring the time and distance required for the vehicle to decelerate to a stop after applying the brakes at a certain initial speed, and the stability of the vehicle during deceleration and the sensitivity of the brakes should also be observed.
Importance: Excellent acceleration performance can make the elderly tricycle more rapid and powerful when starting and overtaking, reduce waiting time on the road, and reduce the risk of being hit by other vehicles. Good deceleration performance can ensure that the vehicle can stop in time and smoothly in an emergency, effectively protecting the safety of the elderly.
Braking performance
Test method: In addition to the above-mentioned deceleration performance test, the response time of the braking system, the size and distribution uniformity of the braking force can also be tested. For example, professional testing equipment is used to measure the time difference from the moment the brake pad contacts the brake disc to the moment the vehicle stops completely, as well as the distribution of braking force between the front and rear wheels during braking.
Importance: Braking performance is one of the key factors to ensure the safety of elderly tricycles. A reliable braking system allows the elderly to control the speed of the vehicle more confidently during driving, avoiding traffic accidents caused by untimely braking or insufficient braking force.
Riding comfort
Test method: The riding comfort can be tested from multiple aspects, such as the shock absorption effect of the vehicle, the comfort of the seat, the position design of the handlebars and pedals, etc. By simulating different road conditions, the test personnel can take the vehicle for actual riding experience, make subjective evaluations of the vehicle’s bumpiness, vibration frequency, etc., and combine professional measuring instruments to collect objective data on the vehicle’s shock absorption performance. At the same time, ergonomic analysis is conducted on the material, hardness, support of the seat, and the height and angle of the handlebars and pedals.
Importance: When riding a three-wheeled scooter for the elderly for a long time, if the comfort of the vehicle is poor, it is easy to cause physical fatigue, backache and other problems in the elderly, affecting their use experience and willingness to travel. Good riding comfort can improve the satisfaction and happiness of the elderly, making them more willing to choose a three-wheeled scooter for the elderly as a means of travel.

Tester training: Select a group of testers with rich driving experience and professional knowledge, and conduct unified training for them to familiarize themselves with the test process, master the test methods and instrument operation skills, and ensure the accuracy and reliability of the test results. During the test, the testers are required to operate strictly in accordance with the test standards and operating procedures, and record the test data and observed phenomena truthfully.
Actual test operation: According to the test methods of the above key indicators, each elderly three-wheeled scooter is tested in turn in terms of steering flexibility, acceleration and deceleration performance, braking performance and riding comfort. During the test, attention should be paid to controlling variables, such as maintaining the same load and the same road conditions, to ensure the comparability of the test results. At the same time, the entire test process should be recorded, including taking videos and photos, so as to be used in subsequent data analysis and report writing.
Data collation and analysis: The data obtained from the test are collated and summarized, and the data are deeply analyzed using statistical methods and data analysis software. By comparing the test results of various indicators of vehicles of different brands and models, the excellent performance and deficiencies can be found to provide strong data support for subsequent evaluation and decision-making.
IV. Evaluation and analysis of test results
Horizontal comparative analysis: Compare the test results of different brands and models of elderly three-wheeled scooters on various key indicators horizontally to analyze the gaps and advantages between the products. For example, vehicles of brand A are outstanding in steering flexibility, with light steering and quick response; while vehicles of brand B are more excellent in braking performance, with strong braking force and short braking distance. Through this comparative analysis, wholesale buyers can intuitively understand the characteristics and performance levels of each product, so as to choose the most suitable products for purchase and sale according to market demand and the preferences of target customer groups.
Vertical comparative analysis: For elderly three-wheeled scooters of different models and configurations of the same brand or manufacturer, a vertical comparative analysis is conducted. This helps to understand the improvements and innovations of enterprises in product design and R&D, as well as the impact of different configurations on the lightness of vehicle handling. For example, the new models of a certain brand have significantly improved the acceleration and deceleration performance compared with the old models, which may be due to the use of more advanced motor technology and the optimization of the vehicle’s transmission system.
