I have a RYCA seat and rear sets on my bike.  The pegs are high and also rearward.  I am in good shape for my age and I do not have any issues with the pegs - but they certainly were not built for comfort.  Getting your feet up on the pegs does require mobility and a bit of determination.  The low mounted clip on handlebars on my bike require you to lean forward which does help a bit with the seating position.....if you have a more standard height handlebar it likely would make the leg position more uncomfortable.

Also the RYCA seat padding is made from layers of thin foam that appears to have been some kind of repurposed game board.  The sharp edge is uncomfortable when you put your legs down when stopped - I took the seat apart and built one with a lot better padding so I could do 200-300 mile rides in a day.
