The fine print says it all, and it is restrictive. But, as someone who has lived in France for about 16 years, I have certainly met people that meet the requirements. Do they want to have an e-bike? Maybe. I could see someone trading their vehicle and taking advantage of this but probably get another vehicle within the year. There are plenty of e-bike options in France though, and individual cities also offer interesting refunds.
Also, something else we think about a lot in France is the annual cost:
A car costs about €6,000/year (financing, insurance, repairs, tolls, fuel, etc.)[1].
