HOW TO PRONOUNCE "NIKE" IN ENGLISH? - 10 POINTS?

I'm a Spanish boy, and I want to know how to really pronounce the name of the sports brand "Nike".

I know American people pronounce it like /NY-KEE/, but I'm not not sure if it's the same for the Britain (and real) English.

Thank you!
Update: You can find the pronounciation I told about before (/NY-KEE/) by watching this video (just in case I didn't explain myself right...):
