Do you want a true wheelchair or a mobility scooter ?
There's a big difference.
Here's what I currently consider the best and most affordable mobility scooter available.

ask the pros!
talk to your health care’s physical therapy and/or prosthetics departments. no one should be thinking of assistive devices without professional oversight.
fyi: whether single tip cane, walker, quad-cane, wheelchai…to scooters, these are decisions that need medical input.
what’s more: they should be paid by your healthcare providers
after 22 years with a quad-cane, I now worship my power-assist wheelchair (max 2 miles) and scooter (up to 10 miles). 😎
