I have very few details about it but here I go:
I watched a few episodes on French television (Canal+ I think) during late 90s/early 2000s but it was definitely not a French series
It was about some sort of vigilante
It took place in some future dystopia
Most of the scenes took actions during the night (or in a dark environment)
The hero was a white male who wore a special suit and had a futuristic bike
The suit and the bike were in a secret hideout, it felt really Batman-inspired
Alas, I don't remember anything about the plot, but if you have questions I will try to answer them.
