Bicycles that drag are a drag, is all. John rides motorcycles, and has different priorities.
Any bike with a motor is technically a motorcycle, and anything you ride on with 2 inline wheels is technically a bicycle. If you want to talk about arbitrary legal definitions then it depends on where you are, and the definitions vary widely. While my more recent high power ebikes would need registration and plates in much of the world but thankfully no here, the benefits of regen are the same, and those are:
1. Recovering some of the kinetic energy produced by the electric drive, and putting it back in the battery instead of wasting it as heat dissipated to the outside world. There is no valid argument against increased efficiency, and the only way any ebike won't be more efficient without regen is if the ebike is just a bicycle with electric assist and the primary drive is leg power. Only then would the added drag of a motor capable of regen be a negative in terms of efficiency.
2. Reduced maintenance time and cost- I use my ebikes as primary transportation, and want them to be absolutely reliable and as trouble free and convenient as possible. Just put the key in and go, and plug in to charge upon arrival, so it's always ready to go. I put lots of time into builds, but once finished I hate fiddling with them. Despite the lower traction I even opt for longest wear bicycle tires. Most builds though I use motorcycle tires, despite the greater rolling resistance, because they result in far fewer flats and in every case so far I've been able to ride the flat home or to a tire shop for repair. That means no carrying tools or tubes on my rides, and never getting stuck in the hot sun or rain dealing with a flat.
3. Increased safety- Having fresher and cooler mechanical brakes for emergency stops is always a good thing, especially going fast or down hills.
BTW, my ebike where I've noted regen regen recovery rates of 20-25% on a regular basis is just as much a bicycle as any on the forum even by Chalo's very prejudiced definitions. It's got functional pedals that I use to assist the motor on every ride. Sure it's a drag to ride if I run out of juice, but in 10 years of service that happened only once. That was back when I knew almost nothing and miscalculated how much battery to carry for a 80 mile ride, and I came up just a mile short. I had no Cycle Analyst back then to know my battery pack's status, but had I taken a bit more time for lunch and opportunity charge, the motor drag during pedal only operation would be a 100% non-issue for 10 years. I sometimes use the motor drag for some extra exercise. I tried pedaling against regen once, but that was a bit too intense of a workout...I'm by no means a cyclist though I am an ebiker through and through.
