as others have stated, there is no such thing as truly easy beethoven, but in terms of movements that I have played and found more manageable, here goes:
op 13 Adagio cantabile (the famous pathetique 2nd mvt). have someone show you the fingering, because it's not intuitive based on the way the score is written (specifically how the hands are distributed)
op 14 #1, mvts 1 and 2. certainly some challenges to be had here, hand crossings, octave passages in the first mvt, but one of the easier fast movements to play. the second movement is not technically challenging, but as others have mentioned, difficult musically. Andras Schiff called the whole sonata "frightfully difficult."
op 27 #2, mvts 1 and 2. doesn't need much explanation here, discussed exhaustively elsewhere.
op 28 pastoral, mvt 1...some of it. the development section is quite challenging, with some difficult contrapunctal work, but the main theme is really quite fun and you can dabble with this for a while without getting frustrated. just save the tougher bits for later.
op 31 #2, mvt 2...some of it. once that broken arpeggio figure enters, it's pretty challenging, especially balancing the hands.
op 57 mvt 2...the theme and first 2 variations. the 3rd variation is significantly harder. but it's pretty fun to play in my opinion.
I would say that all of these are more challenging than op 49, and that several have moments that are quite challenging by most standards. the question is, do you want to play some, but not "finish" the piece? I actually find it enjoyable to dabble with the easier bits of a hard piece of music, but for completists that's not a good way to go about life. anyway, good luck with it.
