Absolutely not!
A 4-wheeled rollator is a "walking aid," not a "transportation tool."
Its design purpose is to help users walk independently and maintain balance, not to be pushed by others or to be sat on and propelled.
Push the bike first, then step – but don't push too far.
The correct sequence is:
1) Push the bike forward slightly.
2) Step with one foot.
3) Step with the other foot.
4) Repeat.
Simply put, "bike first, feet follow."
The answer often points to a tool that assists walking while providing stable support—a four-wheeled walking aid.
When a person can still walk but is unsteady, a four-wheeled walking aid helps them walk more safely and further, while maintaining physical function, compared to using a wheelchair directly.
