Are the handlebars at the same height relative to the saddle on both
bikes? You might have a more upright posture on the MTB (handlebars
higher than saddle) and are not used to bending over further on the Trek.

In addition, I would also compare the distance from the saddle to the
handlebar grips to see whether that is causing you to reach further.

I assume 'crippling back pain' is muscular and goes away after a short
time off the bike and not sciatic/ pinched nerve pain that drops you to
the floor (speaking from experience).
