Data analysed SmartPLS 4.0.
 Findings: study found that two factors TPB- attitudes perceived behavioural control- positively impact while subjective norm does not. Three diffusion innovation (DOI)- trialability, compatibility, observability- attitude towards EV adoption.
 Unique Contribution Theory, Practice Policy: Findings explain electric vehicles Rwanda. They can serve as an objective basis for policymakers upscale uptake Rwanda brings perspective context on adoption.
