After two big victories against lesser sides, Orgryte presented Reading with a higher class of opposition, even if they are rooted to the bottom of the Swedish top-flight.
American midfielder Bobby Convey and Korean forward Seol Ki-Hyeon got Reading's goals, with Bikey sent off on the stroke of half-time following an off-the-ball incident.
That denied the Cameroonian a further 45 minutes in which to impress manager Steve Coppell, who has been considering making an offer to Lokomotiv Moscow for the versatile 21-year-old.
Reading also lost defender Ibrahima Sonko to injury in the second half, leaving them potentially short with less than two weeks remaining before their first Barclays Premiership match against Middlesbrough.
