Strider is originally based off a manga series published in 1988 co-owned by Capcom.
When the SAM Coupé computer (which was derived from the Spectrum but had similar graphics power to 16-bit machines) was launched, US Gold declared that "If, as with Strider, we've already produced a games across all common formats, all we have to do is simply take the code from the Speccy version and the graphics from the ST and sort of mix them together. This should take one bloke around two weeks at most". Whether this was the case or not (and it doesn't sound like good programming practice), the game was never converted to the system.
Strider for the Playstation is a port of the original arcade game, and is included on a separate bonus disc with Strider 2.
