Best Bike to ride before a good listening session

I have a friend in his mid-70s who is still quite a strong road rider.  He also has an e-mountain bike that he rides both around here (MI) and at his place in Colorado.  He really enjoys it.  Not sure on the brand but it is probably a good one - I would suggest checking out what is available at your LBS.  Having good tech support may be more critical for an e-bike than for purely mechanical bikes.
Interesting to see this thread come up again.  I wouldn't change what I wrote 10 years ago....

Any bike I am riding at the time is the best. There is no bad ride.

Interesting thread, and glad it was resurrected.

Cycling has been my passion and my livelihood for a long long time. I’ll share a joke:

Q.What’s the difference between a large
pizza and a bike shop owner?

A. A large pizza can feed a family.

The bike(s) you currently own are the best ride before a listening session. I happen to be partial to Scott Mtn bikes and Giant for road and gravel.

Live in NYC ridding a bike you could get killed.

Riding my bike before a listening session results in me sleeping through my listening session. I love riding and still try to put in a couple thousand miles per year, but age is creeping up on me..... Don't really care which of my bikes I ride, depending on the type of ride. I enjoy any of 3 road bikes, my MTB, my gravel bike, or either of my 2 cruisers. 

Yamaha YDX Moro Pro. WAY FUN mountain bike.
