Bike as service vehicle?
 

A few years ago my Parkinson's became bad enough that I had to walk with a cane or walker. However, I could always ride a bicycle. So I was wondering... could a bike be considered a service aid in this instance, i.e. take into hotel room or into zoo's, etc. for use as a walking aid - places you can take a wheelchair

BTW, I've since had brain surgery and am able to walk unaided. And cycle too.

I believe so, at least in my area. I know of a guy who had a nasty fall and had to have brain surgery. He rides a trike and the zoo allows him to ride inside. More power to you with your physical issues!

I use both Trek 800 Singletrack, and TiLIte Aero Z wheelchair. The former for longer exploration and outdoors, the latter for indoors and shorter distances. I deal with hip issues, mixed type Cerebral Palsy, and Spina Bifida. I hop sometimes, push sometimes, pedal sometimes.

Shouldn't be an issue.

I had started boxing four years ago, haven't looked back.
DBS in 2016.
Last year decided it was time to run, so I've done 5Ks. Not the fastest.
I can ride a bike, but when I took my hands off to shift, tremor city! Can not control a bike with hand when pushing it.
Finally discovered I qualify to use a Catrike for Triathalons as a Parathlete, so learning to swim.
Did my first sprint Triathalon. Dead last, but I finished.
