Are recumbent bikes better than upright bikes for back pain?

Across the reviewers and communities we read, the consensus is that recumbent bikes put significantly less stress on the lower back because the seat provides lumbar support and a reclined position, where an upright bike offers none. Multiple r/cycling threads specifically cite reduced lower-back strain as the main reason riders switch. They are widely recommended for rehab, joint issues, and seniors, though they generally burn fewer calories per session than aggressive upright or spin riding.
