The wheelchair implementation efficiency is not high? Is your rear wheel configuration right?

The rear wheel, as the key component to drive the wheelchair forward, has an important impact on the user's feeling and function.

A wheelchair has four wheels on the ground. Only with the cooperation of front wheel guidance and rear wheel drive propulsion can the wheelchair move smoothly. In the process of traveling, the contact area between the rear wheel and the ground is relatively larger, so the configuration of the rear wheel has an important impact on "whether the wheelchair is smooth and comfortable".

How does the size of the rear wheel affect the user?

At present, the common rear wheel sizes of wheelchairs on the market are 24 inches and 26 inches, which meet the needs of most wheelchair users, but the common size is not necessarily suitable for everyone.

Therefore, the appropriate rear wheel size should be configured according to individual height, hand length and wheelchair rear seat height. The size of the rear wheel will directly affect the range of wheelchair rear seat height that can be set.

Users who are tall and tall need rear wheels with larger diameters, while children and users who are petite prefer rear wheels with smaller diameters.

Effect of unsuitable rear wheel size

If an inappropriate rear wheel size is used, it will lead to unreasonable adaptation of the rear seat height, decreased comfort at the backrest, and long-term use of the unsuitable rear seat and backrest will lead to incorrect sitting posture of the user and affect the body bones.

Improper rear wheel size directly affects wheelchair propulsion. It is difficult for hands to touch the hand push ring, resulting in low wheelchair implementation efficiency, compensatory force of arm muscles, and easy to cause arm muscle strain.
