I am a senior and I ride an adult e-trike. Can i ride that on the trail? My family wants to do this trail but I do not have good enough balance to ride a two wheel bike.

yes. I saw quite a few people riding those.

Yes my mother-in-law used her when we rode the trail this last summer and the bus does take your kind of bike

It is a very wide road. The only problem that you might run into is getting it back to the top of the mountain in the bus. I do not think you will run into a problem but i would give them a call to double check

Yes, the trail is nice and wide enough for a tricycle without worrying about taking up too much space. However you may need to do additional planning as far as how you will transport it to and from the trail.
