Ok. Don't judge. Hahahaha. But my eclipse is decked out like a Christmas tree. I should be embarrassed. But I'm not. (Ok. Maybe I am a LITTLE bit embarrassed. Lol!)
I got tired of trying to find accessories so I improvised.
I have this for a phone holder -

For water (or insert beverage of choice here) I have this -
https://www.amazon.com/gp/product/B000Y ... UTF8&psc=1 I have it attached to the handlebars and have used it with a water bottle or 16 oz tervis tumbler with wine or coffee depending on the time of day.

I have these tethers - one attached to the mirage drive in case I have a bad day and one hanging from the handlebars with a whistle on it in case I have a worse day. Don't judge. I'm old. Hahahaha.

That's pretty much it. Until I find an appropriate mermaid figurehead. Hahahaha. (Ok. Even I wouldn't go that far. Probably.

)
Still using it every morning before work. I have the best gym and I don't mind sharing it with the great blue herons, the turtles and the beavers. Hahahaha.
