How soon you can ride a bicycle after lumbar spine surgery depends on the age of the patient, the type of surgical treatment taken and the specific circumstances of recovery. For example, patients with fractures in the lumbar spine, or those who have undergone open surgery for disc herniation, nucleus pulposus removal, or intervertebral fusion, need to wait for the fracture to heal or the fused bone to heal before they can engage in more vigorous sports. Cycling requires the patient to lean forward, which has a greater impact on the lower back. However, for some lumbar surgeries, such as simple herniated disc nucleus pulposus removal without fusion or internal fixation, patients can return to normal in about 4-6 weeks after surgery. Therefore, it is possible to ride a bicycle for 4-6 weeks, or at most 8 weeks, after surgery for this group of patients. Therefore, for patients of different ages and with different conditions, the duration of bicycling will vary.
