there was a show in the early 90s i thik it was maybe even earlier about a cop who was a time travellor on a mission to arrest criminals who had escaped through time back to the 1990s. I can't recall the name but I loved the show.

also i clearly remember a show about a guy who was dressed up in souped up moto gear riding around on a motorcyde saving ppl. It was Saban show I dont think I think it was a prime time show. I could be wrong and it might be a show from Saban.
