Why Scyther can't learn Fly?

In the Pokédex entry of FireRed, X, etc. it is mentioned that it very rarely spreads it wings to fly. It also had flied in the anime. Why it can’t learn fly? Even a Pidgey can learn Fly why Scyther not? Please don’t tell Game Freak logic. It makes sense that Scizor can’t learn as it is now part steel, it is now heavier and much slower. But is not Scyther blindingly fast as mentioned in Pokedex entries?

I think it is more about Bug types not learning Fly in general. The only bug types that can learn fly are Genesect, which has been shown to be strong enough to carry Ash and fly in the Anime, Vikivolt, and Volcorona, both of which kind of glides around like Whimiscott/Eldegoss as well as being heavier Bug type; heavy enough to carry a ten year old but light enough to float. :P

Also, if Scyther can Fly, so can Scizor, despite being unable to fly. :P

Hope I helped!

Scyther is fast,but it’s wings are for acceleration,not for taking a human on it.

U see,what can those thin membranous wings do? It is like a glass cannon.Easily gets OHKOed. So it cannot learn fly

You partially answered the question yourself. The only reason why it would make any sense for Scyther to NOT learn fly is because it’s evolution Scizor can not possibly fly.
