Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: 1. Minimum age of 65 years 2. Body length between 170 and 195 cm (to be able to cycle on bicycle) 3. Problems looking behind while cycling and remaining seated on saddle 4. Regular cycling experience (2-3 times per week 15 min); 5. The ability to cycle for 20 minutes continuously; 6. Adequate visual and aural functions to understand the experiments, follow instructions, and give feedback to the researchers.

Exclusion criteria

Exclusion criteria: 1. Serious visual impairments that limit normal road traffic participation. 2. Serious aural impairments. The subjects should be able to hear and understand instructions given in a loud voice; 3. History of bicycle falls resulting in serious injuries.

Design outcomes

Primary

Measure	Time frame
The main study parameters of the kinematic study is the van der Laan technology acceptance scale. This scale has two sub-scores: one for usefulness and one for satisfaction.	—

Secondary

Measure	Time frame
Secondary study parameters are the cycling speed and bicycle lateral acceleration and steer angle, which represent cycling behaviour and bicycle stability. The bicycle lateral acceleration is assessed from the accelerometer in an inertia sensor attached to the frame of the bicycle. A speed measurement device is mounted to the rear wheel. The steer angle is calculated from the position of the inertia sensor attached to the steer relative to the one attached to the bicycle frame. Furthermore, from the semi-structured interview: Perceived usefulness, Perceived ease of use, Subjective norm (opinion of others) and Identity to get a better understanding of the underlying considerations and reasoning of the older cyclist.	—
