How is a four wheeler electric scooter? Is it expensive?

I saw a guy riding one of those in a four-lane heavily traveled road that was a feeder road to I-95. He was quite elderly and it was surely illegal. Cars were dodging around him at 40 or more mph. It was impossible to see him up ahead. Just saying—they aren’t intended for road use.

Is this for you or grandmom and how old is grandmom. You first need to research. As said have an evaluation done. I know there was a post where someone spent thousands for a scooter that kept falling backwards because of the way it was constructed. There are all types and weights. Some now just fold down and can be put in a trunk of a car. Others are pretty heavy and need a special ramp for towing it.

Install? Do you mean putting them together? I think its fairly easy on the ones that you may need to take apart for easy transporting. But I don't think there isn't any installing. What you may want to do is find a durable equipment store near you that sells scooters and see what is available and how they work.

Be careful. My friend told me her dad, who had Alzheimer's, would use it as a car, and go off disappearing, using it as a car, because he wanted to visit friends.

Also, check size. While four wheels are generally more stable, you also need to consider the body/frame size of the scooter. If you are looking at a small frame you should be fine regardless of the number of wheels, but if the reason you are considering four wheels is to support a more substantial body weight - and the actual frame of the scooter is also wider as a result - you can run into more usage problems.

My FIL is a larger man (6'2" and over 300lbs) and when he was still able to get out and about with his scooter he insisted on switching from 3 wheel to a 4 wheel. When he had the 3 wheel, he never had any problems with getting in and out of places that I can remember. Once he got the 4 wheel scooter, it did come with a substantial size increase and with that he ran into all kinds of problems with getting in standard doors and even some oversized doors, getting down typical aisles in stores and restaurants. And maneuvering bathrooms became a nightmare.

He essentially limited himself drastically to where he could and could not go with that one choice.

Also, listen carefully to the OT's recommendations. They know a lot about what does and does not work for people. They rarely steer people wrong.

Have an OT do an assessment between 3 and 4 wheels to make sure it can be safely driven including backing up. The 3 wheelers can tip over. Once you buy, you cannot return.
