Adjusting the seat clearance to the pedals: Sit with your rear as tight as possible to the backrest.
You should be able to step through the pedals with the legs slightly angled.
Adjusting the backrest tilt: Adjust the backrest so that the steering wheel can be reached with slightly angled arms.
The shoulders should also have backrest-contact when steering.
Adjusting the seat inclination: Adjust the seat surface inclined slightly upwards so that the thighs rest loosely on the seat surface and the pedals can be pushed through without much effort.
Adjusting the headrest: To avoid whiplash injury to the cervical spine, there should be no more than 4 cm between the back of the head and the headrest, and the top of the head should be flush with the top of the headrest.
2. Change body posture
Dynamic sitting means to continuously change your sitting posture and leg position.
The adjustment of the lumbar support should be changed from time to time in order to prevent fatigue and maintain a relaxed posture.
