Not esk8 but PEV related.
Gist of it:
"France does not look kindly upon e-bike owners that hot rod their wheels. The country has just introduced a law that could see “offenders” slapped with a maximum fine of €30,000 (US$34,000), and up to a year in jail. And they could have their driving license suspended for up to three years.
There are no caveats or loopholes, either – do anything to tune your e-bike for more speed or power and you could feel the wrath of the new law, known as French statutory provision L317-1. The rules also apply to importers, distributors and dealers."
