Introduction: Biking has been linked to upper extremity nerve entrapment, namely ulnar nerve entrapment at the wrist. This is usually known as Guyon canal syndrome. Cycling palsy, often known as handlebar palsy. Carpal tunnel syndrome and median nerve entrapment at the wrist are both possible.

CASE DESCRIPTION
A 36-year-old right-handed analyst with no medical history reported periodic numbness in his left thumb for one year, with no nocturnal worsening. This was associated with atrophy of his left thumb muscles. He can still grip stuff without difficulty. He has experienced neck ache for the past 6 months without receiving arm irradiation. There is no muscle weakness or alterations in bowel or bladder function. His MRI of the left wrist and hand was normal. He has been using kettlebells to develop his muscles for several years. For 3-4 years, he practiced shooting and mountain biking sans gloves for 2 hours once a week, covering approximately 10 kilometers.
