The main difference between the big wheel and the small wheel is that the users of the big wheel can push it by themselves or let others push from behind, while the wheelchair of the small wheel can only be pushed by others. 

 

    Considering in general, the elderly are unlikely to push themselves. Then the choice of big wheel and small wheel mainly depends on whether you need to move upstairs and downstairs. If you need to move to the third floor or above, it is recommended to buy a small wheelchair wheels, which is relatively light. If it is an elevator room or the ground floor, there is no problem of moving. It is recommended to buy a large wheels. Relatively speaking, the large wheelchair wheels is a little labor-saving. 

 

     If you want to consider putting in a car trunk, if it is a sedan, you can put a general wheelchair. If the space in the trunk is small, you can buy a wheelchair with a foldable back function. Hope it helps you. If you have any questions, please contact us freely.
