Troubleshooting, fault clearance and repair
9.1.1 Sitting discomfort
Around 50% of all pedelec riders experience
sitting discomfort:
• Pressure pain in the sitting bones
• Pain in the lower back
• Pressure pain and numbness in perineal region
9.1.2 Pain in hips
Lower back pain is often not caused by the back
muscles, but by the iliopsoas muscle instead. This
muscle is part of the inner hip musculature and
flexes the hip. It is attached to the thigh bone and
reaches up to the spine. Pain can occur in the
back if this muscle is strained too much or
shortened.
9.1.3 Backache
Riding a pedelec strengthens the back
musculature. The greater the saddle-to-bar drop
is, the greater the strain on the back musculature
is. At the beginning, a posture where you lean too
far forward can lead to pain in the back, arms and
wrists. The abdominal muscles are the
counterpart to the back muscles and stabilise the
pelvis and the back. Back pain is thus often
caused by weak abdominal muscles.

Solution
• Adopt an optimal riding position (see
Section 6.5.2).
• Adjust the saddle height and tilt (see
Section 6.5.4).
• Wear cycling shorts and use chamois
cream (see Section 6.12).
• Use an ergonomically adjusted saddle
(see Section 6.5.4).
• Ride standing up now and again.
Solution
• Strengthening exercises for the iliopsoas
muscle
• Stretching exercises for hip flexors and
extensors.
Solution
• Contact specialist dealer. You need to
adopt a more upright sitting position (see
Section 6.5.3).
• Stretching exercises for the back and
abdominal muscle ligaments and
moderate bicycle training will lengthen the
tendons and build new back and
abdominal muscles.
The desired position can be adopted after
a period of training.
