Back pain while biking is usually caused by poor biking posture. I
would suggest you to improve your posture riding bike. If you still
have the back pain, then you should consult a chiropractor. You can

treatments.

Reduced flexibility also. Stretching the various muscle groups that
attach direct to the spine and hips (assuming it's lower back) may
alleviate discomfort.

The psoas muscle in particular, can get shortened and cause poor posture
and back pain.

You often see professional racers stretch on the bike. They're not immune.
